It’s been a little over four years since a major fire ravaged France’s iconic Notre Dame de Paris cathedral, causing an estimated $865 million of damage to the majority of its roof and recognizable spire. Since then, the French government, engineers, and a cadre of other dedicated restoration experts have been hard at work rebuilding the architectural wonder, which is currently slated to reopen to the public by the end of 2024.

It’s a tight turnaround, and one that would be much easier to meet if carpenters used modern technology and techniques to repair the iconic building. But as AP News explained earlier this week, it’s far more important to use the same approaches that helped first construct Notre Dame—well over 800 years ago. According to the recent dispatch, rebuilders are consciously employing medieval era tools such as hand axes, mallets, and chisels to reforge the cathedral’s hundreds of tons’ worth of oak wood roofing beams.

Although it would progress faster with the use of modern equipment and materials, that’s not the point. Instead, it’s ethically and artistically far more imperative to stay true to “this cathedral as it was built in the Middle Ages,” explained Jean-Louis Georgelin, a retired general for the French overseeing the project.

Thankfully, everything appears to be on track for the December 2024 reopening. Last month, overseers successfully conducted a “dry run” to assemble and erect large sections of the timber frame at a workshop in western France’s Loire Valley. The next time the pieces are put together will be atop the actual Notre Dame cathedral.

As rudimentary as some of these construction techniques may seem now, at the time they were considered extremely advanced. Earlier this year, in fact, researchers discovered Notre Dame was likely the first Gothic-style cathedral to utilize iron for binding sections of stonework together.

It’s not all old-school handiwork, however. The team behind Notre Dame’s rebuilt roofing plans to transport the massive components to Paris via trucks, and then lifted into place with help from a large mechanical crane. Over this entire process, detailed computer analysis was utilized to make absolutely sure carpenters’ measurements and handhewn work were on the right track. Still, the melding of bygone and modern technology appears to perfectly complement one another, ensuring that when Notre Dame finally literally and figuratively rises from the ashes, it will be as stunning as ever.

What to consider when choosing a travel drone

When shopping for a travel drone, you should consider your budget and how you will be using the drone first and foremost.

Camera

We live in a 4K world at the moment, but camera tech doesn’t necessarily stop there. Some higher-end drones can capture 5K and beyond, allowing oversampled 4K footage with more detail or simply a bigger frame so you can crop in later while maintaining a full-res picture. Ideally, you’ll get 4K footage at 60fps with a reasonable megapixel count for photos. Of course, you’ll want to think about how you will use that footage later on. You may not need 4K at a high framerate if you’re trying to make a simple travel blog. In fact, it may hinder your editing process. Find a balance between easy edibility and high quality, then stick with it.

Weight

You’re traveling with these machines, so you want them to be as light as possible. Most only weigh a few pounds at most. But be sure to note the 250g threshold. A drone weighing 250 grams or more requires registration with the FAA before you can fly. Conveniently, our top pick on this list weighs 249 grams for this exact reason.

Obstacle avoidance

While drones have gotten easier to fly in recent years, you still have to navigate the learning curve. Unfortunately, tons of trees, houses, and power lines are littering that learning curve. Higher-end drones offer dedicated object avoidance systems that automatically stop a craft from smacking into something it shouldn’t. Top-tier models offer object avoidance in almost every direction, but more consumer models typically only see in front of them and sometimes to the side. It’s a nice touch if you’re learning and want to minimize possible damage.

Range

Some high-end drones can go nearly 20 miles away from their pilots, but local regulations and practical considerations make that unlikely for most users. If you’re considering two drones and opting toward one because it has a longer range, just be sure you will need that range. If all you plan is to fly it up into your neighborhood or over the lake, you don’t need a massive flight area.

Flight time

Drone batteries are small, and the juice inside can fade fast if conditions are less than perfect. Every gust of wind or fancy maneuver requires more power to execute. Our top pick, the DJI Mini 3 Pro, promises “up to 34 minutes” of flight time, but that “up to” is doing a lot of work. Add wind or complex movements, and that will drop quickly. You also couldn’t stay fully airborne for 34 minutes unless you’re cool with the craft falling out of the sky once the battery is exhausted.

Should you buy the Fly More combo?

DJI typically offers its drones on their own or as part of a Fly More combo, which includes a carrying case, extra rotors, and (most importantly) extra batteries. The Fly More combos typically offer a better deal than buying all the products together. And since you’re definitely going to want extra batteries (and a dedicated charger that can handle more than one cell at once), we recommend you invest upfront.

Keeping a portable charger in your car, bag, or pocket prepares you if an emergency arises as you’re running out of power. Say you’re stuck in a raging blizzard, your car in a snowbank on the highway, and you need a tow if you don’t want to stay where you are overnight. No problem, you can just call for roadside assistance, right? That isn’t the case if your phone happens to run out of power and you have no way to charge it back up again. It’s not the case unless you carry a portable power bank, that is. A battery pack to charge your phone, laptop, and other devices can make all the difference when your battery’s nearly dead and draining fast. The right power bank will let you top off all your essential gear to get your devices through the day (or longer). Fortunately, we’ve collected some of the best portable chargers available and sorted them into categories that should fit most people’s needs.

As the best multipurpose portable charger, the Anker PowerCore Fusion 10,000 is especially convenient, even among power banks. It’s a fairly small portable charger with two ports and a 10,000mAh battery, but you can also plug it into an outlet and draw power from there. This is extremely convenient for travelers and rolls two devices into one well-crafted package. Its only downside is that it’s a little larger and heavier than a standard wall-based charger. The shape can also make it awkward to fit into some places, and the weight might cause it to fall out of a loose socket.

Best for travel: Belkin Gaming Power Bank with Stand

SEE IT

Why it made the cut: Belkin’s gaming charger with a stand lets you power up your phone while watching media or playing games.

Specs

• Charging speed: 12W

Pros

• Stand makes continuing to use the phone while charging more convenient
• Stand is retractable

Cons

• Fast charging is hit or miss

It seems like combining a portable charger and a stand would be a no-brainer, but surprisingly few companies have actually made them. Belkin’s Gaming Power Bank with Stand is the best portable charger for travel. It offers a retractable shelf with a lip that makes it easy to continue enjoying media or games on your phone as it charges. Unfortunately, its fast-charging seems to be hit-or-miss: Some users report speedy refueling, while others aren’t as impressed with how quickly their devices get juiced up. It’s a great charger when you have a few hours to kill and need to top off your phone’s power, but not the most efficient option.

Best with flashlight: superallure Solar Charging Power Bank

You can get 48 extra hours of battery depending on what you’re charging, and a USB port allows you to charge another device while using wireless charging. Our only complaint? It tends to show dirt easily. Its powerful charging and wireless transcendence across brands make up for this.

Best large: Goal Zero Sherpa Wireless Portable AC Power Bank

Goal Zero

Why it made the cut: This large portable charger is like a mini generator in your pack.

Specs

• Dimensions: 7.69 x 5.49 x 1.02 inches

We’ve reviewed Goal Zero’s Yeti 1000 Core generator in the past and gave it kudos for its durability and battery capacity. Goal Zero took both of those aspects and packed them into an ever smaller package with its Sherpa Wireless Portable power bank. It’s great if you need major power on the go without needing an entire solar generator. And you’ll get plenty of use out of it: this power bank can charge a smartphone 8 times; a tablet three times; a laptop two times; and a GoPro 18 times. It also supports wireless charging. Talk about a multi-hyphenate. Its aluminum unibody is durable, and it easily integrates with other Goal Zero products, like solar panels. It’s pricey, but we think it’s worth it if you’re looking for a tough portable charger that’s made to last.

Best for laptops: Anker 747 Power Bank

Reports suggest that INIU customer service has done right by users who reported getting a nonfunctional unit, though, shipping out replacements quickly.

What to consider when buying the best portable chargers

Portable chargers come in a variety of shapes and sizes. For many, they’re just random bricks that you plug stuff into, with little to differentiate between them. While they may look the same, there are aspects of a charger’s design that vary, which you should keep in mind when picking one out. 

How much power can it hold? Will it fit in my pocket or my backpack? Does it have the ports to charge all my devices or just my phones? If you know these things, you can buy the right portable charger for your needs:

How big is the battery?

Portable chargers are really just fancy plastic and a circuit board wrapped around a battery. The most important thing you need to know about any portable charger is how big that battery is. Portable chargers measure their power storage in Milliamp Hours (mAh), a unit of measurement that shows how much power a battery can hold. The number of charges it can provide will depend on the specific device, but it’s a good way to get a general sense. 

If you plan to keep a laptop going through your workday or charge many devices simultaneously, you will likely want the largest battery possible, which tends to range between 2,000mAh and 10,000mAh for most users, depending on the devices they cart around.  If you’re just looking to top off your phone to get through a busy day, you can probably get something smaller. More storage translates to a larger, more expensive charger, so that’s definitely good reason to go small if that’s all you need.

How much space does it take up?

As we said, more power means a bigger battery pack. It doesn’t matter how impressive a portable charger’s specs are if it’s a pain to carry around. Power banks range in size from slim and pocket-sized to whopping boxes as big as a book. They can get heavy, too. While it can be tempting to get the biggest, most powerful charger, you will make a better choice if you’re realistic about your needs.

What are you charging?

When you choose a portable charger, you’ll want to remember what you will be using it for. Most people tend to buy chargers to top off their best tablet, new iPhone, Bluetooth headphones, or noise-cancelling earbuds: As a result, most portable battery packs are made for that purpose. If you’re looking to charge something bigger, like a laptop, you should make sure to get a charger that has the right ports for the job. For larger devices, you will also need to make sure the charging rate is actually high enough to replenish your laptop’s battery.

How quickly can it charge your devices?

The second major consideration when buying a portable charger is how fast it charges. Different batteries can charge devices at different rates, depending on the device and the cable used to charge. In general, portable chargers tend to be slower than plugging a device into a wall, but some are faster than others. Check the maximum charging rate, measured in watts (W), to determine how quickly most devices will charge.  For a portable charger, 18 watts is considered a good charging speed. 27 watts is excellent.

Sometimes companies will show a battery’s voltage and amperage rather than a rate in Watts: In that case, multiply the two numbers to get the rate in watts. For example: If a charger serves 5 volts at 2 amps (5V/2A), its charging rate is 10W. (5 x 2 = 10).

How fast does the battery pack charge itself?

It’s also important to look at how long you need to juice each charger back up to full capacity. When you’re in a pinch and pressed for time, knowing you can fall back on a fast-charging portable device offers peace of mind. A good charging rate, for example, is anywhere from 3 hours (111.11 mAh/min) to 4 hours (111.48 mAh/minute), though there have been packs that have charged back up to 100% in just 20 minutes or so. The larger the battery bank, the longer it will need to charge, especially when you factor in larger capacities. This rate may differ from pack to pack if the charger can power other devices.

Possessing the best portable charger can be a real lifesaver under the right circumstances. There isn’t that much to the tech, but there’s still a surprising amount of variation from device to device. It pays to learn their ins and outs to tell the difference, whether you need a slim power bank to get a quick jolt or something massive that can keep a laptop going for days. No matter what, we can all agree on one thing: Nobody likes having a battery die on them.

Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now.

Our writers and editors have combined decades of experience covering and reviewing consumer electronics. We each have our own obsessive specialties—from high-end audio to video games to cameras and beyond—but when we’re reviewing devices outside of our immediate wheelhouses, we do our best to seek out trustworthy voices and opinions to help guide people to the very best recommendations. We know we don’t know everything, but we’re excited to live through the analysis paralysis that internet shopping can spur so readers don’t have to.

The Federal Trade Commission’s ongoing attempt to rein in Amazon entered a new phase this week, with the regulatory organization recommending both the company and its home surveillance system subsidiary Ring receive multimillion dollar fines in response to alleged monopolistic practices and data privacy violations.

According to an FTC statement released on Wednesday, Amazon disregarded children’s privacy laws by allegedly illegally retaining personal data and voice recordings via its Alexa software. Meanwhile, in a separate, same-day announcement, the commission claims Ring employees failed to stop hackers from gaining access to users’ cameras, while also illegally surveilling customers themselves.

Amazon relies on its Alexa service and Echo devices to collect massive amounts of consumer data, including geolocation data and voice recordings, which it then uses to both further train its algorithms as well as hone its customer profiles. Some of Amazon’s Alexa-enabled products marketed directly to children and their parents collect data and voice recordings, which the company can purportedly retain indefinitely unless parents specifically request the information be deleted.  According to the FTC, however, “even when a parent sought to delete that information … Amazon failed to delete transcripts of what kids said from all its databases.”

[Related: End-to-end encryption now available for most Ring devices.]

Regulators argued these privacy omissions are in direct violation of the Children’s Online Privacy Protection Act (COPPA) Rule. First established in 1998, the COPPA Rule requires websites and online services aimed at children under 13-years-old to notify parents about the information collected, as well as obtain their consent.

According to the complaint, Amazon claimed children’s voice recordings were retained to help Alexa respond to vocal commands, improve its speech recognition and processing abilities, and allow parents to review them. “Children’s speech patterns and accents differ from those of adults, so the unlawfully retained voice recordings provided Amazon with a valuable database for training the Alexa algorithm to understand children, benefitting its bottom line at the expense of children’s privacy,” argues the FTC.

“Amazon’s history of misleading parents, keeping children’s recordings indefinitely, and flouting parents’ deletion requests violated COPPA and sacrificed privacy for profits,” said Samuel Levine, Director of the FTC’s Bureau of Consumer Protection, in Wednesday’s announcement. “COPPA does not allow companies to keep children’s data forever for any reason, and certainly not to train their algorithms.”

[Related: Amazon’s new warehouse employee training exec used to manage private prisons.]

The FTC’s proposed order includes deleting all relevant data alongside a $25 million civil penalty. Additionally, Amazon would be prohibited from using customers’ (including children’s) voice information and geolocations upon consumers’ request. The company would also be compelled to delete inactive children’s Alexa accounts, prohibit them from misrepresenting privacy policies, as well as mandate the creation and implementation of a privacy program specifically concerning its usage of geolocation data.

Meanwhile, the FTC simultaneously issued charges against Amazon-owned Ring, claiming the smart home security company allowed “any employee or contractor” to access customers’ private videos, and failed to implement “basic privacy and security protections” against hackers. In one instance offered by the FTC, a Ring employee “viewed thousands” of videos belonging to female Ring camera owners set up in spaces such as bathrooms and bedrooms. Even after imposing restrictions on customer video access following the incident, the FTC alleges the company couldn’t determine how many other workers engaged in similar conduct “because Ring failed to implement basic measures to monitor and detect employees’ video access.”

[Related: Serial ‘swatters’ used Ring cameras to livestream dangerous so-called pranks.]

The FTC’s proposed order against Ring would require the company to pay $5.8 million in fines to be directed towards consumer refunds. The company would also be compelled to delete any data, including facial information, amassed prior to 2018.

Amazon purchased Ring in 2018, and has since vastly expanded its footprint within the home surveillance industry. In that time, however, the company has found itself under fire on numerous occasions for providing video files to law enforcement entities without consumers’ knowledge, lax security, as well as promoting products via its much-criticized found footage reality TV show, Ring Nation.

Best for campers: Wise Owl Outfitters Hammock  

Wise Owl Outfitters

SEE IT

If your favorite grad is equipped with just about everything they need to make it through a backcountry trip, get them camping gifts to introduce even more relaxation and fun to their next outdoor escape. A camping hammock is a perfect way to sit back, take a nap, read a book, or drink a calming beverage outdoors. This is the best hammock from Wise Owl and weighs under 2 pounds, including the hanging straps, so it’s perfect for campers who prioritize portability. When packed down, it’s about the size of a grapefruit, so your grad should be able to easily carry it with them or keep it stashed away in their car. Each hammock comes with tree straps and carabiners for easy setup, with no need for any additional equipment. It comes in over 10 colors so that you can choose their favorite. It’s 9 feet long and 4.5 feet wide, with a 400-pound weight limit, which should be suitable for just about any user. You can even grab a two-person hammock (weighing only 5 ounces more) if they tend to go camping with a partner or friend.

Best for grad parties in the backyard or backcountry: Ultimate Ears WONDERBOOM 3

Brandt Ranj

SEE IT

No graduation gift guide would be complete without some great speakers. If your recent grad is always on the go—heading out for day hikes, camping trips, beach hangouts, long bike rides, and more—you can’t go wrong gifting them a portable Bluetooth speaker. No matter where they are or what they are doing, a smartphone and a compact speaker will provide the perfect soundtrack for any outdoor activity. The Ultimate Ears WONDERBOOM 3 is an excellent option, weighing under 1 pound and equipped with a flexible handle that can easily attach to a backpack, bike basket, or belt loop. It’s only 4 inches tall, but the small, compact design doesn’t mean you sacrifice anything when it comes to sound. The portable speaker can reach up to 87 decibels (equivalent to standing next to a loud blender or vacuum) and produces full 360-degree sound coverage. This powerful Bluetooth speaker can also withstand the elements and is one of our favorite waterproof speakers for a good reason; it has an IP67 rating, which means it can survive being dropped into a body of water up to a meter deep for half an hour, plus it’s dirt/dust-resistant. In addition, the battery lasts a full 13 hours, so your grad can jam outside all day long. And, if they want to be a party-goer and a party-thrower, you can up the energy with a portable party speaker.

Best for hikers: Smartwool Hiking Crew Socks  

Smartwool

SEE IT

A hiker is only as good as their socks are strong, so give a grad who loves to ramble amongst the rocks a pair that will last. While socks may seem like a simple gift, a quality pair or two is one of those hiking gifts that can go a long way. You’ll be taking care of an essential need any avid hiker has and investing in their overall outdoor experiences. Take it from us: nothing ruins a hike faster than angry blisters and constant friction. Smartwool hiking socks come in various colors and sizes, both men’s and women’s. From a tried and true brand, these socks are designed for rugged day hikes and moderate backpacking. An elasticized arch brace provides extra support, medium cushioning absorbs impact, and a flat-toe seam keeps things comfortable. Made from Merino wool and nylon, these socks will keep their feet warm even during cold winter hikes. If your loved one likes to embark on a variety of adventures, you can check out Smartwool’s other socks specifically designed for activities like running, cycling, skiing, and more. There’s a reason we listed them as our favorite wool socks.

Best for interval training to interviews: Garmin epix Pro and Garmin fēnix 7 Pro

Garmin

SEE IT

Whether your grad is thinking more about the backcountry or the boardroom, they could use a smartwatch that helps them get where they need to be when they need to be there. And when it comes to multi-band GPS smartwatches, Garmin makes the best adventure accessories out there. Endurance athletes to purposeful wanderers can benefit from the rugged, sensor-embedded case, metrics-rich displays, and accurate navigation resources found in Garmin’s newest Pro editions of the company’s multisport timepieces—available in multiple sizes and colors with different types of scratch-resistant/solar-charging glass.

Best for your grad’s new apartment: Fuzzy Ink Wilderness Print

Fuzzy Ink

SEE IT

The perfect grad gifts for outdoor lovers aren’t always the ones they’ll bring on their adventures—they can be ones they’ll appreciate before and after an excursion. A woodsy print or poster is a great present for a graduate who needs a little help decorating their new apartment. At this point, they might have all the gear they need, but what they probably don’t have are elegant pieces that express their personality but also provide a sense of maturity for an adult abode. This print from Fuzzy Ink is an artistic way for your grad to stay inspired. It measures 18 inches by 24 inches and is printed on coated paper with a matte finish, so they won’t have any trouble finding a great spot to display it. This print quietly depicts the beauty and awe that many outdoor enthusiasts find so mesmerizing about being in nature. From the crackling campfire to the expansive display of fir trees, this piece will surely bring joy to a grad who longs to roam around the forest.

Best for outdoor athletes: CamelBak Octane Dart Hydration Pack

CamelBak

SEE IT

Any outdoor lover knows how important it is to stay hydrated. Whether hiking, cycling, or running, drinking water is key to preventing heat stroke, dehydration, fatigue, and other issues. Of course, a water bottle is the first thing we think of when it comes to H2O on the go; however, bottles can be bulky and cumbersome. So, if you want to get your grad a great outdoor gift that prioritizes function and efficiency, we recommend a CamelBak Hydration Pack. This multisport hydration backpack can hold 50 ounces of water and easily straps to your back with a long drinking tube and trap management to make hydrating hands-free. All they need to do is bite down and suck to get as much water as necessary—no need to stop during a long run or bike ride to grab a water bottle. The 3D vent mesh provides lightweight comfort and airflow, while front harness pockets can hold snacks, sunscreen, and other essentials. Reflectivity strips are added for extra safety during early morning or nighttime exercise. Your grad will be able to get a run in anytime, anywhere, and stay hydrated all the while. If you’re looking for more options, consider our list of the best hydration packs.

Best personalized gift: Engraved Compass

Etsy

SEE IT

A personalized gift is always a good idea, especially when you’re celebrating a significant achievement. Giving a gift designed specifically for them—something special that only they will have—will let your grad know how much you care for and support them. If you want to give a personalized gift suited for the outdoors, check out these engraved compasses. You can choose from existing mountainscapes or upload your own favorite photos and illustrations to be perfectly recreated on the compass’s cover. Practically any part of the compass can include etching, so you won’t have to choose between a picture or a message. You can even ask for your own handwriting to be impressed on the metal so your graduate can take a piece of you with them no matter where they travel.

A useful graduation gift for the outdoors: Victorinox Swiss Army One-Hand Trekker Knife

Victorinox

SEE IT

Outdoor enthusiasts know that it’s essential to prioritize gear that is lightweight, portable, and multipurpose. You will rarely find a seasoned camper lugging around a toolbox, though the need for various utensils and instruments is frequent. From quick repairs to food preparation, a survival tool or multipurpose knife is a helpful gift for anyone who spends a lot of time outside (they can also be pretty practical for indoor use). A Swiss Army knife is practical, classic, and cool. A household name when it comes to compact knives, the Trekker lives up to the hype. Its attached tools include a wood saw, large blade, 3-millimeter and 5-millimeter screwdrivers, wire stripper, can opener, tweezers, toothpick, and more. It’s one of those camping gifts that offer pretty much everything you need to make it through the trek without any issues. A knife like this is a thoughtful graduation gift that they are guaranteed to use for years to come.

Best thoughtful: Paddywax Candles Parks Collection

Paddywax Candles

SEE IT

A candle is a fantastic gift for any graduate, signifying new beginnings and ordaining their adult apartment, or childhood bedroom, with sophisticated, balanced scents to keep them calm as they figure out their next steps. We’re a fan of scented gifts in general. But if your recent grad pines for the outdoors but doesn’t have time to travel just yet, a candle that brings nature to them is even more highly recommended. Paddywax has created a National Park Service-inspired collection that features the complex aromas of our country’s natural wonders. “Yellowstone” has hints of sagebrush and fir, the “Great Smoky Mountains” features Maplewood and moss, “Acadia” has seagrass and driftwood, while the “Grand Canyon” smells like cactus flowers and fern. Each candle is 11 ounces and has a burn time between 50 and 60 hours. When they’ve used up every drop of wax the candle has to offer, grads can upcycle the jars and repurpose them as plant pots, beauty tool holders, catch-alls, and more. Best of all, Paddywax donates a minimum of $25,000 per year to the National Parks Foundation, so your gift will not only go to your graduate but support the beautiful natural landmarks they love so much.

Best for day trips: YETI Packable Lunch Bag

YETI

SEE IT

There is only one thing better than a day outdoors, and that is a day outdoors with snacks. Whether they plan on packing a lunch for a mountaintop picnic or bringing a few celebratory drinks to a grad party on the beach, beverages, and munchies are a must-have for your graduate’s next outside hang. A cooler is the best way to keep their tasty treats fresh all day long, so they never have to worry about their food heating up in the sun while they hike or swim. This YETI lunch bag is the perfect gift for grads to take food outside or pack a tasty lunch for their new job. Available in two sizes, a standard box or larger bag, and a variety of colorways, this pack uses Coldcell Flex insulation” technology and a “thermosnap” closure to keep food at the correct temperature, hot or cold. The adjustable grid means you can set the size by simply closing the top hook into any one of the available hoops. That way, the lunch bag can easily fit under a desk or be stuffed with snacks and drinks using all of its available 15.75 inches. This bag will pair well with just about any outdoor excursion, so your grad will be able to pack all the necessities and then some.

Best wearable: Outdoor Life Tee

540Brands

SEE IT

If you want to get sweet, versatile graduation gifts guaranteed to make them smile, go with cute graphic tees like this one from Outdoor Life. Available in both men’s and women’s sizes, the “Go Play Outside” slogan is a fun way for you to tell everyone you see where your priorities lie. Made from 100-percent cotton and available in five colorways, this T-shirt will complement any hunter, angler, hiker, camper, surfer, sailor—just about any outdoor enthusiast you could think of. The soft material makes these tees particularly great for lounging around a campfire, though we recommend sizing up for maximum coziness—your grad will thank you.

Best for dirty hiking clothes: STNKY Bag Pro Wash Bag

STNKY

SEE IT

STNKY’s Bag Pro Wash Bag is the simple gift our adventurous grad didn’t know they needed. The zip-up laundry bag can hold all of their dirty clothes during multi-day camping and hiking trips to prevent unwanted odors and bacteria from getting onto their clean ones. When it’s time to wash their clothes, the STNKY bag can be unzipped and turned inside out, at which point the clothes will fall into the washing machine without being touched. The bag itself is also machine washable, which is a nice bonus. Anyone who struggles to stay organized and sanitary during their next outdoor trip will love this gift.

Best portable firepit: Colsen Tabletop Portable Fire Pit

Colsen

SEE IT

Sometimes setting up a big outdoor fire pit isn’t feasible or reasonable, but that doesn’t mean giving up s’mores for the night. Colsen’s Tabletop Portable Fire Pit runs on the company’s odorless liquid fuel, can be set up and ignited within a few minutes, and produces flame up to one foot tall for roughly 45 minutes. This is the ideal gift for someone who’s into glamping or wants a fire pit they can use indoors and out at any point during the year. The fact that you don’t need firewood to ignite it is particularly important because rainy weather can make dry fuel hard to find. And if you happen to have a grad living somewhere with a sizeable backyard/patio, you can give them a tasteful taste of the campfire life at home with a Solo Stove Bonfire firepit.

Best firestarter: Pull Start Firestarter

Pull Start Fire

SEE IT

On the other hand, if you’re shopping for someone who spends days upon days out in the woods, they’re going to need Pull Start Firestarter. The fire starter is literally ignited by pulling a string built into its small box. Smoke will begin to billow from the box, indicating that the fire starter will be fully ignited within three seconds. It lasts up to 30 minutes once fully ignited. Beyond the convenience of not having to strike a match, keeping a pack of these around can be helpful during an emergency. It’s very difficult to light wet wood with a match, but prolonged exposure to a fire starter can do the trick. Whether they’re trying to save time or their own life, your grad will appreciate having a three-pack of Pull Start Firestarter in their pack.

Best hard cooler: RTIC Ultra-Light 55 Quart Hard Cooler

RTIC

SEE IT

No campsite or boat is complete without a cooler that can reliably keep foods and beverages cold for hours—or days—at a time. If you’re shopping for a grad who’s planning a big summer trip, there’s a good chance Ultra-Light 55 Quart Hard Cooler is the perfect gift. The high-capacity cooler has three inches of insulation to maintain a consistent temperature inside, but it was engineered to be nearly a third lighter than the competition. This means it’ll be easier to carry when filled with ice, food, and dozens of cans. A cooler is one of the few gifts that may actually last your grad a lifetime, so it’s important to make the right choice. If you know they tend to pack extra light, RTIC also offers a 32-Quart model of this same cooler. Want more options? Check out more of the best coolers for camping.

Best for post-trail drinks: Hydro Flask 25 oz Ceramic Reusable Wine Bottle

Hydro Flask

SEE IT

Enjoying a bottle of wine on a mountain sounds like a dream—but wine bottles and hiking don’t exactly mix. Give your grad the gift of sneaky boozing with this ceramic reusable wine bottle from Hydro Flask, which fits one 750 mL bottle of wine. It’s dishwasher-safe for easy cleaning and BPA-free for peace of mind. TempShield double-wall vacuum insulation keeps whites chilled and reds at room temp, and a ceramic-lined interior prevents flavor transfer. Although it’s advertised for wine, we think it’s also perfect for any spirit: Our favorite nature-inspired aqua vitae is Tin Cup Whiskey, cut with water from the Rocky Mountains and named after the tin cups miners used to drink. Need a more traditionally shaped option? Check out our favorite insulated water bottles.

Best unbreakable glasses: Silipint Silicone Pint Glasses

Silipint

SEE IT

We’ve included the Silipint in our best camping gifts guide, but we think it makes a great gift especially for someone who may be too transient for real drinkware. These shatterproof “glasses” are made of 100% food-grade silicone, meaning you don’t have to deal with dangerous broken glass. Plus, they’re a fun, bright way to reduce the amount of plastic your grad may use between graduation and their very first job.

Best for ski lodge lounging: Chaco Ramble Puff Ankle Boot

Amanda Reed

SEE IT

Chaco is known for its rugged and arch-supporting sandals, but we think their covered shoe offerings deserve some praise. The Ramble Puff Ankle Boot feels like a down parka for your feet, and they’re perfect for throwing on after a day of skiing or hiking. And, water-resistant rip-stop nylon means they’re not just indoor shoes—they can hold up in the great outdoors. If you’re looking for something that slips on, the Ramble Puff also comes in a clog style just as comfy and dreamy as its boot brethren. Our staff writer lives in both the clog and boot for women—don’t ask her to pick her favorite. Speaking of puffy stuff …

Best for camp comfort: Therm-a-Rest Honcho Poncho Down

ThermaRest

SEE IT

We all know the importance of having appropriate layers for hiking—but what if you want to stay warm without having to wear the same jacket you’ve worn all day. The Honcho Poncho from Therm-a-Rest (also makers of excellent sleeping pads) combines the lightweight, warm properties of 650-Fill Nikwax Hydrophobic Down with a water-resistant 100% recycled polyester shell for a wearable sleeping bag. You can wear it around the campsite or campfire or lay it out in your tent and use it as a blanket. Its front pocket doubles as a stuff sack to make it easy to stow away back into your pack (or to use it as a lite pillow).

Best for camp chefs: Opinel Nomad Camping Kitchen Utensil Kit

Opinel

SEE IT

These knives are great for a grad who trying to step up their outdoor cooking game. The kit comes with a serrated folding knife, a folding corkscrew knife, a pocket peeler, a beechwood cutting board, and a microfiber cleaning cloth that doubles as a travel pouch. A Virobloc safety ring is attached to all knives/peelers to make it safer to open and transport the kit. Your grad never has to struggle to cut a piece of campfire-cook beef or a hunk of crusty bread again.

Best hiking boot: Vasque Breeze Waterproof Hiking Boot

Tony Ware

SEE IT

Your grad deserves a new pair of hiking boots for successfully climbing the mountain that is college. This one from Vasque is comfortable—our assistant managing editor (his ankles and dog shown above) says, “Lightweight, breathable, and comfortable to … boot … the Vasque Breeze immediately impressed me by requiring zero break-in, then continued to impress me with its stability and traction.” This means grads can climb the highly-graded mountain of post-grad life and worry more about their rent than getting blisters. They’re waterproof and made of sustainable, durable materials for years and years of adventures.

Best headlamp: BioLite 800 Pro

BioLite

SEE IT

Grad gifts are all about shiny new things, and this new headlamp from BioLite should excite your night crawler. It packs 800 powerful, bright Lumens to illuminate any dark trails … or the way to the bathroom at night. Your grad will get 150 hours of power on low; seven hours on high; and 8 hours on reserve. It recharges using a micro USB port, and includes a Constant Mode for full illumination without auto-dimming. Plus, 3D SlimFit tech gives you bounceless, slipless, and near-weightless wear. Being comfortable and able to see where you’re stepping? Sounds like a win.

Best solar generator: Jackery Portable Power Station Explorer 300

Jackery

SEE IT

Jackery topped our list of the best solar generators, and we love the company’s small-but-mighty portable power station that can be charged by a wall outlet, car outlet, and the sun (!!!). The solar panel isn’t included, but you can get this bundle that solves the lack of solar panel upon purchase. It’s easy to carry at 7.1 pounds and can charge up to six devices while your grad is on outdoor adventures. Your grad may go outdoors to unplug, but you’ll get peace of mind that their phone or other powered essentials won’t die out in the wilderness.

Things to consider when picking gifts for folks who love the outdoors

From lite hiking gifts to entertaining accessories to full-on camping gifts, you can help recent graduates prepare for whatever their next exploration entails. Or, for graduates moving to a new city or starting a new job and unsure they’ll get out much in those early post-grad days, give graduation gifts that remind them of what they love, from naturally scented candles to beautiful nature prints. The key is determining their favorite outdoor activities, skills, comfort level, and existing accouterments, allowing you to match the grad with the gift.

Cold weather is prime time for humans to stay inside and snuggle up with loved ones. For our primate cousins, cuddling may even keep them healthy, as frosty temps and social bonds seem to go together like hot chocolate and marshmallows. Chilly temperature behavior, as it turns out, may also alter the course of evolution.

A study published June 1 in the journal Science found that a species’ long-term adaptation to life in extremely cold climates led to the evolution of successful social behaviors. Asian colobines living in colder regions saw genetic changes and adaptations to their social behaviors including extended care by mothers, which increased infant survival and the primates’ ability to live in the large complex multilevel societies we see today.

[Related: These primate ancestors were totally chill with a colder climate.]

An international team of researchers from the United States, China, the United Kingdom, and Australia studied how langurs and odd-nosed monkeys adapted over time. These members of the colobine family are leaf-eating monkeys that have been on Earth for about 10 million years. Their ancient ancestors dispersed across the planet’s continents and learned to live in tropical, temperate, and colder climates. 

“Virtually all primates are social and live in social groups,” study co-author and  University of Illinois Urbana-Champaign anthropologist Paul A. Garber said in a statement. “But the groups differ in size and cohesiveness. There are those that live in units of two or three individuals and others living in communities of up to 1,000 individuals.”

According to Garber, genomic studies suggest that the harem unit of organization—one male with two or more females and their offspring—was the ancestral norm for Asian colobines. Males are intolerant of other rival males and will fight to protect their turf. In some species, the females will stay with their natal group, while in others, both sexes leave to join or form new harems.

More complex societies formed over time. Some odd-nosed monkeys still form harems, but aren’t territorial. “This means their group territories can overlap and there are times they may come together to forage, rest and travel,” said Garber. 

Snub-nosed monkeys form a multilevel or modular society where multiple harems remain together throughout the year and create a large, cohesive breeding band. The team on this study recorded a society of about 400 individuals and breeding between individuals from different harems was common in golden snub-nosed monkeys. This inter-harem breeding happened roughly 50 percent of the time.

The study used ecological, geological, fossil, behavioral, and genomic analyses, and found that the colobine primates that lived in colder places tended to live in larger and more complex social groups. The glacial periods over the past six million years likely promoted the selection of genes that are involved in cold-related energy metabolism and hormonal regulation in the nervous system.

Black-and-white snub-nosed monkeys in some parts of China live in low-oxygen elevations up to about 13,500 feet where night time temperatures can drop below zero on the coldest evenings. The Odd-nosed monkeys living in extremely cold locations developed more efficient pathways for dopamine and oxytocin. Oxytocin particularly is an important neurohormone for social bonding and this hormonal efficiency may lengthen the time a mother monkey takes care of her baby. This led to longer periods of breast-feeding and increase in infant survival.  

These adaptive changes appear to have further strengthened the relationships between individual monkeys, increased tolerance between males, and encouraged the evolution of more complex and larger multi level societies that go a long way. Strong social bonds can even help gut bacteria health in some monkeys.

In future studies, the team is interested in studying how changes in mating and social behavior may be the result of genetic changes from past environments and other social factors from the past. 

“With climate change becoming an hugely important environmental pressure on animals, it is hoped that this study will raise awareness for the need to investigate what course social evolution will take as the prevailing climate changes,” study co-author and University fo Western Australia biological anthropologist Cyril Grueter said in a statement. “Our finding that complex multilevel societies have roots stretching back to climatic events in the distant evolutionary past also has implications for a reconstruction of the human social system which is decidedly multilevel.”

If you’ve bought shoes, torn into beef jerky, or taken certain medication recently, you have likely handled at least one tiny silica gel packet. After briefly wondering why your new backpack contained a squishy little warning-labeled pillow, you probably chucked it into the garbage with the rest of the packaging.

Yet those little packets are as useful as they are ubiquitous, and you can find plenty of uses for silica gel around your home. It’s better to give them a second, third, or fourth life instead of sending them directly to the landfill. 

Although silica beads are not gems, the porous mineral does come from the ground. Silica is harvested through a “straightforward” mining process using open pits or dredging, according to Robert Goodin, a mineral commodity specialist with the US Geological Survey’s National Minerals Information Center. He says this usually removes vegetation and disturbs the ground’s top layer, and adds that explosive charges will occasionally be used to break apart the rock.

[Related: Which expiration dates actually matter?]

“These little silica gel packets, they’re in everything, but [use in desiccation is] actually a very small percentage of what this industrial sand is used for,” Goodin explains. “It’s less than 1 percent of the eventual end use.” He estimates that over 60 percent of silica sand—similar to regular sand but with much more silica—goes to the oil and gas industry for fracking and other needs. Glass production uses up another roughly 10 percent.

“Recently, [the US has] been the top producer, a major exporter and self-sustaining in a lot of these end-uses for silica, so we have a strong silica—or industrial sand—mining industry” in this country,” Goodin says.

What happens if you eat silica gel?

Despite their ominous, all-caps warnings about consumption, silica gel packets are generally considered non-toxic. The real concern is the size of the beads—it’s pretty easy for a child to choke on the packet or the beads within it, although some beads are large enough for adults to choke on, too. Swallowing silica gel can also lead to dehydration, which could irritate your throat and nose, and cause stomach pains, vomiting, constipation, or nausea.

Even so, spending a lot of time up close with silica can lead to health problems. According to Goodin, industrial workers exposed to silica dust may develop respiratory illnesses if inhaled.

And Britta Baechler, senior manager of ocean plastics research at Ocean Conservancy, notes that some silica gel packets feature a color-changing moisture indication. These aren’t supposed to be used near food and contain a compound known as cobalt chloride, which several chemical manufacturers list as an irritant and a carcinogen.

“Overall it seems that when they do not contain cobalt chloride, silica gel packets are relatively safe to use,” Baechler says. Nevertheless, you should avoid reusing these packets for any food-adjacent uses, just in case.

How to use silica gel around your home

Even if you shouldn’t use silica gel packets around food, there are still plenty of ways to safely reuse the desiccant, but you’ll have to reactivate the packets first.

Paper-based heirlooms—think old books, Gramma’s wedding photo album or your children’s handmade holiday decorations—are also frequently threatened by insidious moisture, leaks, or humidity. Tuck some silica packets into your memory box and breathe a little easier.

Protect—or revive—electronics

You’ll need quite a few to be effective, but keeping silica gel packets packed away with cameras, film, smartphones, video tapes, laptops, and other water-sensitive electronics and accessories can keep them safe until subsequent use. Dropped your phone or tablet in the bath? Try using a slew of silica gel packets to adsorb the water and bring the device back from its watery doom.

Keep moisture-prone areas dry

Your bathroom, basement and attic, are all places that can accumulate moisture easily. Adding silica gel packets near areas that might fog up, like windows and mirrors, can help prevent that slightly-annoying or even damaging condensation and slow down the growth of mold.

[Related: The right way to wash your waterproof clothes]

Preserve unique, special-purpose, or expensive materials

Leather and sports gear might be fine in a bit of rain, but prolonged exposure to moisture can ruin, stain or mildew different specialty fabrics. And any boxes of seasonal clothing or items you only use once a year (think: holiday sweaters and decor) might get wet long before you open them up and realize it. Silica gel packets tucked into pockets and between layers of fabrics can adsorb water before anything is ruined. Other water-sensitive materials such as seed packets can benefit from nearby silica gel packs, and you can even speed up drying flowers with silica. 

What happens to silica beads in the environment?

For most silica gel packets, a single use is all they’re likely going to get. Still, the packets that encase the silica gel beads are a relatively understudied source of single-use plastic pollution, Baechler explains.

“By function, [silica gel packets are] a desiccant,” Baechler says. “So if these packets are being dumped into waterways, or even onto land, it can dry out whatever environment ends up in, which can be problematic.”

[Related: How to go zero-waste at the grocery store]

Additionally, silica works as an insecticide for indoor and outdoor uses in powdered form on “stored grain, other food, feed and ornamentals; in food handling areas; and on pets and their living/sleeping quarters,” according to a US Environmental Protection Agency fact sheet.

“That means it’s being applied in an environmental setting,” Baechler adds. “I would surmise that if silica is used in this way and released into the environment, especially in large quantities that could have some impacts in terms of water retention in ecosystems and, perhaps, impacts on [animal and plant life] as well.” 

For now, at least, the environmental effects of silica gel are uncertain, but we think it’s better to be safe than sorry.

We live our entire lives surrounded by them. They slam into us constantly at more than 700 miles per hour, sometimes hurting, sometimes soothing. They have the power to communicate ideas, evoke fond memories, start fights, entertain an audience, scare the heck out of us, or help us fall in love. They can trigger a range of emotions and they even cause physical damage. This reads like something out of science fiction, but what we’re talking about is very much real and already part of our day-to-day lives. They’re sound waves. So, what are sound waves and how do they work?

If you’re not in the industry of audio, you probably don’t think too much about the mechanics of sound. Sure, most people care about how sounds make them feel, but they aren’t as concerned with how the sound actually affects them. Understanding how sound works does have a number of practical applications, however, and you don’t have to be a physicist or engineer to explore this fascinating subject. Here’s a primer on the science of sound to help get you started.

We can experience sound waves in ways that are more physical, not just physiological, too. If sound waves reach a microphone—whether it’s a plug-n-play USB livestream mic or a studio-quality microphone for vocals—it transforms them into electronic impulses that are turned back into sound by vibrating speakers. Whether listening at home or at a concert, we can feel the deep bass in our chest. Opera singers can use them to shatter glass. It’s even possible to see sound waves sent through a medium like sand, which leaves behind a kind of sonic footprint. 

That shape is rolling peaks and valleys, the signature of a sine (aka sinusoid) wave. If the wave travels faster, those peaks and valleys form closer together. If it moves slower, they spread out. It’s not a poor analogy to think of them somewhat like waves in the ocean. It’s this movement that allows sound waves to do so many other things. 

It’s all about frequency

When we talk about a sound wave’s speed, we’re referring to how fast these longitudinal waves move from peak to trough and back to peak. Up … and then down … and then up … and then down. The technical term is frequency, but many of us know it as pitch. We measure sound frequency in hertz (Hz), which represents cycles-per-second, with faster frequencies creating higher-pitched sounds. For instance, the A note right above Middle C on a piano is measured at 440 Hz—it travels up and down at 440 cycles per second. Middle C itself is 261.63 Hz—a lower pitch, vibrating at a slower frequency.

Understanding frequencies can be useful in many ways. You can precisely tune an instrument by analyzing the frequencies of its strings. Recording engineers use their understanding of frequency ranges to dial in equalization settings that help sculpt the sound of the music they’re mixing. Car designers work with frequencies—and materials that can block them—to help make engines quieter. And active noise cancellation uses artificial intelligence and algorithms to measure external frequencies and generate inverse waves to cancel environmental rumble and hum, allowing top-tier ANC headphones and earphones to isolate the wearer from the noise around them. The average frequency range of human hearing is 20 to 20,000 Hz.

We measure amplitude in decibels (dB). The dB scale is logarithmic, which means there’s a fixed ratio between measurement units. And what does that mean? Let’s say you have a dial on your guitar amp with evenly spaced steps on it numbered one through five. If the knob is following a logarithmic scale, the volume won’t increase evenly as you turn the dial from marker to marker. If the ratio is 4, let’s say, then turning the dial from the first to the second marker increases the sound by 4 dB. But going from the second to the third marker increases it by 16 dB. Turn the dial again and your amp becomes 64 dB louder. Turn it once more, and you’ll blast out a blistering 256 dB—more than loud enough to rupture your eardrums. But if you’re somehow still standing, you can turn that knob one more time to increase your volume to a brain-walloping 1,024 decibels. That’s almost 10 times louder than any rock concert you’ll ever encounter, and it will definitely get you kicked out of your rehearsal space. All of which is why real amps aren’t designed that way.

Twice as nice

We interpret a 10 dB increase in amplitude as a doubling of volume. 

Parts of a sound wave

Timbre and envelope are two characteristics of sound waves that help determine why, say, two instruments can play the same chords but sound nothing alike. 

Timbre is determined by the unique harmonics formed by the combination of notes in a chord. The A in an A chord is only its fundamental note—you also have overtones and undertones. The way these sound together helps keep a piano from sounding like a guitar, or an angry grizzly bear from sounding like a rumbling tractor engine. 

[Related: Even plants pick up on good vibes]

But we also rely on envelopes, which determine how a sound’s amplitude changes over time. A cello’s note might swell slowly to its maximum volume, then hold for a bit before gently fading out again. On the other hand, a slamming door delivers a quick, sharp, loud sound that cuts off almost instantly. Envelopes comprise four parts: Attack, Decay, Sustain, and Release. In fact, they’re more formally known as ADSR Envelopes. 

• Attack: This is how quickly the sound achieves its maximum volume. A barking dog has a very short attack; a rising orchestra has a slower one. 
• Decay: This describes how fast the sound settles into its sustained volume. When a guitar player plucks a string, the note starts off loudly but quickly settles into something quieter before fading out completely. The time it takes to hit that sustained volume is decay. 
• Sustain: Sustain isn’t a measure of time; it’s a measure of amplitude, or volume. It’s how loud the plucked guitar note is after the initial attack but before it fades out. 
• Release: This is the time it takes for the note to drift off to silence. 

Sound’s velocity, or the speed it travels at, differs depending on the density (and even temperature) of the medium it’s moving through—it’s faster in the air than water, for instance. Generally, sound moves at 1,127 feet per second, or 767.54 miles per hour. When jets break the sound barrier, they’re traveling faster than that. And knowing these numbers lets you estimate the distance of a lightning strike by counting the time between the flash and thunder’s boom—if you count to 10, it’s approximately 11,270 feet away, or about a quarter-mile. (Very roughly, of course.) 

A stimulating experience

Anyone can benefit from understanding the fundamentals of sound and what sound waves are. Musicians and content creators with home recording set-ups and studio monitors obviously need a working knowledge of frequencies and amplitude. If you host a podcast, you’ll want as many tools as possible to ensure your voice sounds clear and rich, and this can include understanding the frequencies of your voice, what microphones are best suited to them, and how to set up your room to reflect or dampen the sounds you do or do not want. Having some foundational information is also useful when doing home-improvement projects—when treating a recording workstation, for instance, or just soundproofing a new enclosed deck. And who knows, maybe one day you’ll want to shatter glass. Having a better understanding of the physics of sound opens up wonderful new ways to explore and experience the world around us. Now, go out there and make some noise!

An independent security researcher has found malicious code in 18 Chrome extensions currently available in the Chrome Web Store. Combined, the extensions have over 57 million active users. It’s yet more evidence that Chrome extensions need to be evaluated with a critical eye. 

Chrome extensions are apps built on top of Google Chrome that allow you to add extra features to your browser. The tasks that this customizable feature can do are wide-ranging, but some popular extensions can auto-fill your password, block ads, enable one-click access to your todo list, or change how a social media site looks. Unfortunately, because Chrome extensions are so powerful and can have a lot of control over your browsing experience, they are a popular target for hackers and other bad actors. 

Earlier this month, independent security researcher Wladimir Palant discovered code in a browser extension called PDF Toolbox that allows it to inject malicious JavaScript code into any website you visit. The extension purports to be a basic PDF processor that can do things like convert other documents to PDF, merge two PDFs into one, and download PDFs from open tabs. 

It’s that last feature that leaves PDF Toolbox open for bad intentions. Google requires extension developers to only use the minimum permissions necessary. In order to download PDFs from tabs that aren’t currently active, PDF Toolbox has to be able to access every web page you currently have open. Without this feature, it would not be able to pseudo-legitimately access your browser to the same extent.

While PDF Toolbox seemingly can do all the PDF tasks it claims to be able to, it also downloads and runs a JavaScript file from an external website which could contain code to do almost anything, including capture everything you type into your browser, redirect you to fake websites, and take control of what you see on the web. By making the malicious code resemble a legitimate API call, obfuscating it so that it’s hard to follow, and delaying the malicious call for 24 hours, PDF Toolbox has been able to avoid being removed from the Chrome Web Store by Google since it was last updated in January 2022. (It is still available there at the time of writing, despite Palant lodging a report about its malicious code.) 

Palant had no way of confirming what the malicious code in PDF Toolbox did when he first discovered it. However yesterday, he disclosed 17 more browser extensions that use the same trick to download and run a JavaScript file. These include Autoskip for Youtube, Crystal Ad block, Brisk VPN, Clipboard Helper, Maxi Refresher, Quick Translation, Easyview Reader view, Zoom Plus, Base Image Downloader, Clickish fun cursors, Maximum Color Changer for Youtube, Readl Reader mode, Image download center, Font Customizer, Easy Undo Closed Tabs, OneCleaner, and Repeat button, though it is likely that there are other infected extensions. These were only the ones that Palant found in a sample of approximately 1,000 extensions.

In addition to finding more affected extensions, Palant was able to confirm what the malicious code was doing (or at least had done in the past). The extensions were redirecting users’ Google searches to third-party search engines, likely in return for a small affiliate fee. By infecting millions of users, the developers could rake in a tidy amount of profit. 

Unfortunately, code injection is code injection. Just because the malicious JavaScript fairly harmlessly redirected Google searches to alternative search engines in the past, doesn’t mean that it does so today. “There are way more dangerous things one can do with the power to inject arbitrary JavaScript code into each and every website,” writes Palant.

And what kind of dangerous things are those? Well, the extensions could be collecting browser data, adding extra ads to every web page someone visits, or even recording online banking credentials and credit card numbers. Malicious JavaScript running unchecked in your web browser can be incredibly powerful. 

If you have one of the affected extensions installed on your computer, you should remove it now. It’s also a good idea to do a quick audit of all the other extensions you have installed to make sure that you are still using them, and that they all look to be legitimate. If you not, you should remove them too. 

Otherwise, treat this as a reminder to always be vigilant for potential malware. For more tips on how to fight it, check out our guide on removing malware from your computer.

The Nines are the latest in Klipsch’s wildly popular family of retro-modern, media-friendly powered speakers, which launched in 2020 with The Fives, compact powerhouses that claimed the first HDMI-ARC connection in a bookshelf speaker. Like The Fives and The Sevens before them, a pair of Klipsch The Nines speakers ($1,499) aims to deliver an expressive audio experience that seamlessly integrates with just about any entertainment setup, while exuding a heritage-inspired aesthetic that pays homage to mid-century elegance.

Sarah Jones

SEE IT

Overview

• The Nines are the top of three models in the Klipsch line of Heritage-inspired powered bookshelf (or standmount) speakers.
• The brand’s signature horn-mounted driver delivers a fleshy, high-fidelity presence across an almost multidimensional soundstage.
• These are a great pair of speakers if you have numerous sources but can’t find the space or budget for discrete components.

Pros

• The sound—classic Klipsch concert-like sound
• Plentiful inputs and robust internal amps mean you can skip the added expense of an AV receiver
• HDMI-ARC makes integration in a home theater with a modern TV easy
• Can decode most digital files up to 24-bit/192 kHz resolution
• A built-in phono preamp means no external hardware is needed with moving magnet cartridge turntables
• Dynamic Bass feature can provide enough low-end that a subwoofer is a bonus, not a requirement (a plus in apartments)

Cons

• Price (though they’re a relative bargain compared to many connected stereo speakers)
• Height, weight, and vibration produced mean you need an extremely sizable, sturdy bookshelf, so it’s just better to pay extra for stands
• An external phono preamp can still outperform the build-in signal path

Verdict: Klipsch The Nines speakers exude retromodern style and hypermodern versatility, making them a, well, sound investment for audio-video audiophiles.

The build

The Nines’ warm-and-cozy retro exterior belies their high-tech innards. Vintage-inspired cabinets are finished with handcrafted wood veneers and top-mounted brushed-metal input-selection and volume dials. Speakers are available in walnut or ebony and feature removable magnetic grilles; I left mine off. (A collectible McLaren Edition, designed in partnership with McLaren Racing, is finished in the vibrant orange and white motif of the McLaren F1 dynasty.)

When you describe “the Klipsch sound,” anyone familiar with the brand will immediately think of the visually and audibly recognizable horns, with their clear, commanding presence. The Nines are two-way powered speakers featuring 1” titanium tweeters on Klipsch’s proprietary Tractrix horns. These 90° x 90°, silicone-composite horns stretch from edge to edge, a design optimized for the most efficient high-frequency transfer, for more detailed, accurate sound. (This proprietary technology also aims to minimize reverb from sound reflecting off walls.) Woofers are all-new 8” long-throw fiber composite cones, and cabinets feature rear-firing bass-reflex ports.

Minimalists, rejoice: Because The Nines are self-powered speakers, there’s no need to connect an external amp, receiver, or even a phono preamp. The Nines use a bi-amped design, featuring a built-in 240W RMS (480W peak) amplifier—100 watts to each woofer and 20 watts to each tweeter—optimized with a sophisticated DSP package integrating crossovers, limiters, and EQ.

When it comes to connecting all your favorite sound sources, from your TV to your turntable, these speakers are truly ready to rock (or jazz or hip-hop or house, etc.). Inputs include integrated HDMI-ARC, USB-B, optical, and analog 3.5mm; high-res aficionados will be happy to learn that digital-to-analog conversion is at 192 kHz/24-bit. (One caveat: The Nines do not accept files in the MQA or FLAC formats, so you’ll need to decode them to PCM at your source.) The Nines also have a built-in phono preamp, with a switchable phono/line RCA in and a ground connection, plus a subwoofer out (with a 60Hz crossover). Finally, the Nines offer Bluetooth 5.0 connectivity, including aptX, aptX HD, and AAC support (the former two commonly found on Android devices and the latter the native Apple protocol). However, there is no built-in WiFi/AirPlay/Chromecast/Spotify Connect, etc.

Everything you need to connect your speakers is in the box, including a proprietary four-conductor cable that connects the powered speaker to the secondary speaker (either speaker can serve as left or right); an extension speaker cable; and HDMI, USB-B to USB-A, and AC power cables, plus a no-frills remote (AAA batteries included, though we always recommend rechargeables).

These are big, brawny boxes, measuring 19 x 9.5 x 13 inches, weighing around 28 pounds each, and approaching the size of commercial studio monitors. It’s advisable to place these musical monoliths on stands for optimal response and to avoid vibrations interfering with your turntable. (Klipsch stands feature hidden cable channels and threaded inserts for securing your speakers.) 

Setup is plug-and-play simple and takes just minutes. (A quick note, however, about connecting turntables: When running a phono signal directly from a turntable to your speakers, you might face longer cable paths than you would if you were connecting your turntable to a receiver; be aware that phono cable lengths longer than three feet can degrade sound quality, and plan accordingly.)

Once you’re physically up and running, pair the speakers with your smartdevice and use the Klipsch Connect App as a virtual remote and to access EQ controls and firmware updates. I found the app clumsy and sluggish to connect and update, but very easy to operate. Functions include a customizable three-band graphic EQ with presets, which can be useful if you need to boost mids to hear movie dialog better or crave extra-deep bass in your gaming soundtrack, for example, but listening to music, I left the EQ flat at all times. The app also offers processing compensating for wall or corner speaker placement, a Night Mode that adjusts dynamic range for quieter listening, and a Dynamic Bass function, which boosts low end at low volume levels.

The sound

Decades ago, Klipsch founder Paul Klipsch identified four design principles that he felt led to the most lifelike recreation of the live concert experience at home: high efficiency, low distortion, controlled directivity, and flat frequency response. Together, these principles provide the foundation for the signature “Power Detail Emotion” focus in premier Klipsch towers, and they are well-represented in The Nines.

I used The Nines in a music-only setup, streaming TIDAL over USB from my laptop and over Bluetooth on my iPhone 13 Pro. l connected an Audio-Technica AT-LP140XP direct-drive turntable, A/B-ing a direct phono in using The Nines’ built-in phono preamp and a path through an ART DJ Pre II phono preamp to The Nines as line-in. Spoiler alert: The external preamp won out, delivering slightly cleaner, slightly more dynamic sound, especially at higher volumes. But given the convenience factor, I doubt many Nines users will find their internal preamp (which only supports moving magnet cartridges, FYI) a deal-breaker. It’s just one of several signal paths you can take. These speakers could easily flank the plinth of a quality turntable (with or without a built-in preamp) to create a relatively compact, aesthetically and aurally pleasing listening station in a single connection; a quick flip of the Line/Phono switch and you’re in business.

Because the cabinet is a rear-ported design, for optimal bass response and imaging it’s best to set speakers at least 12 to 18 inches away from the wall, which I did; another selling point for stands. This two-way speaker package produces a wide frequency range of 34 Hz to 25 kHz. I found The Nines’ bass output so deeply extended and articulate that a subwoofer was unnecessary for my music-listening setup. Gamers, hip-hop fans, and action-movie junkies may seek a bigger boom. Still, given how much air these beefy 8” woofers can move, I recommend trying the speakers without a sub first, especially if you are in a shared-wall living situation.

In my large (15×20-foot) listening space, The Nines sounded balanced and natural out of the box. I never felt the need to tinker with the response, choosing instead to dive right in. (That said, if you’re hoping to tease out some nuances, the Connect App gives you access to a three-band graphic EQ with bands centered at 200 Hz, 1 kHz, and 4 kHz; you can save your preferences as custom settings.)

Feeling inspired by The Nines’ bass for days, I queued up Crystal Waters’ classic house banger, “100% Pure Love.” I was instantly transported to the clubs of my youth, triggering the muscle memory of clambering atop massive PA speakers in the days before I knew better. Everything—the bone-melting bass, the silky-smooth, snaking vocals, those knife-edged cowbell clanks—sounded incredibly clear and balanced, with deep, defined lows and ultra-clean, pinpoint-precise highs, even at blow-the-roof-off levels, which is what this track demands. Think of The Nines’ sound as effortless meets in-your-face.

The Nines showcased the modal intricacies of Miles Davis’ “Nardis,” as realized on Bill Evans’ landmark 1968 live recording Bill Evans–At the Montreux Jazz Festival, in astonishing clarity. Every textural detail was brought to life, from the sandpapery slide of bassist Eddie Gomez’ virtuosic fingers traveling down the neck of his instrument to the crisp counterpoint of Jack DeJohnette’s drums as they cascaded into a kaleidoscopic solo.

Because Klipsch speakers are highly efficient, their drivers don’t have to work very hard, which helps bring dynamic range to levels comparable to a live performance. And because they’re bi-amped, they offer great separation between high and low frequencies. To me, the overall effect was that of sitting in the front row, an expansive soundstage washing over me, each instrument presented with remarkable depth and distinct separation.

And although I generally listen at old-lady conservative levels, with The Nines, I never heard compression at high volumes or experienced fatigue over long listening sessions. I found I didn’t need the Dynamic Bass turned on to feel every articulate attack, but YMMV.

The conclusion

More and more, powered home speakers are morphing into entertainment hubs, dishing out everything from built-in streaming to sophisticated DSP to inputs that support every device you own (think the wireless network-enabled KEF LS50 Wireless II and JBL 4305P, among others). Although the all-in-one system is somewhat at odds with the audiophile “mix and match components until it’s perfect” ethos, as The Nines demonstrate, that doesn’t mean you can’t enjoy amazing sound in a convenient package without the expense and learning curve (and clutter!) of building a hi-fi system. The Nines even add the vinyl-friendly preamp that those other WiFi-connected speakers lack.

Considering their lineage and the success of their predecessors, it’s almost a given that The Nines sound amazing. Their sound signature can be characterized by its exceptional coherence, impressive imaging, and a sense of depth that draws you into the heart of the music. Bass is punchy and defined, and the midrange is rich and textured, for a warm and lifelike audio experience. Highs are crisp and detailed, a sparkling presence with no edgy harshness. The Nines’ comprehensive features and seamless connectivity make them standouts in their class.

Using these speakers feels a bit like enjoying the ease and convenience of a soundbar while experiencing the sonic separation, imaging, chest-thumping bass, and room-filling energy of component speakers. Add in their gorgeous vintage looks, and Klipsch The Nines speakers strike an ideal balance between versatility and charm and are sure to satisfy discerning listeners seeking to bring a new dimension of fun to gaming, movies, and, of course, music.

Last month, engineers at Georgia Institute of Technology unveiled a creepy, crawly centipede-inspired robot sporting a plethora of tiny legs. The multitude of extra limbs wasn’t simply meant to pay homage to the arthropods, but rather to improve the robot’s maneuverability across difficult terrains while simultaneously reducing the number of complicated sensor systems. Not to be outdone, a separate team of researchers at Japan just showed off their own biomimetic “myriapod” robot which leverages natural environmental instabilities to move in curved motions, thus reducing its computational and energy requirements.

[Related: To build a better crawly robot, add legs—lots of legs.]

As detailed in an article published in Soft Robotics, a team at Osaka University’s Mechanical Science and Bioengineering department recently created a 53-inch-long robot composed of six segments, each sporting two legs alongside agile joints. In a statement released earlier this week, study co-author Shinya Aoi explained their team was inspired by certain “extremely agile” insects able to utilize their own dynamic instability to quickly change movement and direction. To mimic its natural counterparts, the robot included tiny motors that controlled an adjustable screw to increase or decrease each segment’s flexibility while in motion. This leads to what’s known as “pitchfork bifurcation.” Basically, the forward-moving centipede robot becomes unstable.

But instead of tipping over or stopping, the robot can employ that bifurcation to begin moving in curved patterns to the left or right, depending on the circumstances. Taking advantage of this momentum allowed the team to control their robot extremely efficiently, and with much less computational complexity than other walking bots.

As impressive as many bipedal robots now are, their two legs can often prove extremely fragile and susceptible to failure. What’s more, losing control of one of those limbs can easily render the machine inoperable. Increasing the number of limbs a lá a centipede robot, creates system redundancies that also expand the terrains it can handle. “We can foresee applications in a wide variety of scenarios, such as search and rescue, working in hazardous environments or exploration on other planets,” explained Mau Adachi, one of the paper’s other co-authors.

Such serpentine robots are attracting the attention of numerous researchers across the world. Last month, NASA announced the latest advancements on its Exobiology Extant Life Surveyor (EELS), a snake-bot intended to potentially one day search Saturn’s icy moon Enceladus for signs of extraterrestrial life. Although EELS utilizes a slithering movement via “rotating propulsion units,” it’s not hard to envision it doing so alongside a “myriapod” partner—an image that’s as cute as it is exciting.

Monitors with built-in webcams can make life a lot simpler for people who need to spend time on video calls but don’t want a lot of clutter or devices strewn about their desks. For most people, a dedicated webcam is still the way to go to ensure a sharp feed in meetings, but there’s a growing number of high-end productivity-focused monitors built with video conferencing in mind. Using a monitor with an internal webcam eliminates the unsightly clutter of a larger, standalone webcam. If you’re a laptop user, there’s a good chance you’ll get both a bigger screen to look at and better picture quality when on video calls.

For monitor shoppers, however, a webcam heaps extra factors onto an already-complicated world of specs you need to understand when picking out your next PC display. If you need a bit of guidance, we have some thoughts on how to pick the best monitor with a built-in webcam, including a set of recommendations with awesome options for every kind of PC user.

How we picked the best monitors with built-in webcams

Most monitors do not have a built-in webcam, so we’re working with a much smaller number of monitors than we usually do. That said, all the usual rules for picking a great one still apply.

As a freelance writer who’s covered technology for publications including Engadget, Popular Mechanics, and Reviewed, I’ve spent a lot of time using, researching, and staying up to date on the latest monitors. In addition to testing, I surveyed a wide range of professional reviews and consumer impressions to determine the best monitors with built-in webcams on the market today.

The best monitors with built-in webcams: Reviews & Recommendations

Our list of the best monitors with built-in webcams consists of monitors that make the fewest trade-offs possible while offering all-in-one convenience. We focused on the overall monitor quality first and the webcam quality second, but we ruled out any models that were consistently noted to have poor webcam quality. We also paid attention to other features like connectivity and built-in speakers that can help to further simplify your setup.

Best overall: Dell S2722DZ

Dell

SEE IT

Buy it used or refurbished: eBay

Why it made the cut: Dell’s S2722DZ is an incredibly well-rounded display, making it a perfect pick for home office workers looking for a monitor with a built-in webcam.

Specs

• Size: 27-inch
• Resolution: 2560 x 1440
• Refresh rate: 75Hz
• Ports: USB-C (65W), DisplayPort, HDMI, USB 3.2 (2), 3.5mm audio out
• Panel type: IPS
• Webcam: 5-megapixel IR pop-up camera
• Webcam resolution: 1080p

Pros

• Great value
• Ample connectivity 
• Full-featured webcam

Cons

• Not 4K

Dell makes quite a few monitors with built-in webcams but the 27-inch S2722DZ hits a sweet spot for generalist office workers. The 1440p, “QHD” resolution will be more than adequate for non-visual arts work, watching videos, and even gaming. Its 5MP pop-up webcam can stream in 1080p at 30fps and is compatible with Windows Hello. Though it looks large, you can conveniently tuck it away when it isn’t in use. A pair of built-in 5W speakers and noise-canceling microphones round out the all-in-one package. There are also plenty of ports and connection options, including USB-C (with 65 W of power delivery), HDMI, DisplayPort, and a pair of USB 3.2 ports—plus a 3.5mm audio out if you do decide to upgrade the speakers. Considering its often discounted price tag, it’s an overall value that’s tough to beat.

Best 4K: Samsung M8 Smart Monitor

Amanda Reed

SEE IT

Buy it used or refurbished: eBay

Why it made the cut: The Samsung M8 Smart Monitor stands out in more ways than one, offering all the features you’d expect from a smart TV in a sleek package that’ll look great on your desk. 

Specs

• Size: 32-inch
• Resolution: 4K
• Refresh rate: 60Hz
• Ports: USB-C (65W), micro HDMI 
• Panel type: VA
• Webcam: Detachable webcam with privacy cover
• Webcam resolution: 1080p

Pros

• Built-in processor allows you to use it for basic functions without a PC
• Magnetic webcam that’s removable and adjustable
• Multiple color options

Cons

• Connectivity options may be limited for some
• No Windows Hello support

Plenty of people use their monitor as a TV, whether it’s for console gaming or video streaming, but Samsung’s 32-inch, 4K M8 Smart Monitor goes the extra mile and throws in an onboard processor, allowing to perform basic productivity functions, including video calls, without connecting to a PC. You could call it a smart TV dressed up as a monitor.

When disconnected from other devices, you control the M8 through a smart TV-esque smart hub, complete with a range of streaming apps (plus support for Amazon Alexa and Apple AirPlay), a remote control, and, naturally, built-in speakers.

Wired connectivity options are considerably more limited, however, with only upstream and downstream USB-C ports, plus a micro HDMI port on offer (no DisplayPort or additional USB ports for connecting multiple peripherals). You can also connect wireless devices via Bluetooth.

As for the webcam, it isn’t built-in, so much as it is a fully removable webcam that comes baked into the monitor. That gives you the ability to tilt the Full HD (1080p) webcam to get the right angle when you need to. The webcam also comes with a camera cover, an always-welcome feature to let you prevent people from seeing you when you aren’t ready for them.

Best 27-inch: HP E27m G4

HP

SEE IT

Buy it used or refurbished: eBay

Why it made the cut: With plenty of connectivity options, HP’s E27m G4 monitor is an ideal all-in-one hub for anyone with lots of peripherals.

Specs

• Size: 27-inch
• Resolution: 2560 x 1440
• Refresh rate: 75Hz
• Ports: USB-C (65W), DisplayPort, HDMI, USB 3.2 (4), Ethernet, 3.5mm audio out
• Panel type: IPS
• Webcam: 5-megapixel IR pop-up camera
• Webcam resolution: 1080p

Pros

• Loads of ports
• Pop-up, adjustable webcam
• Front-facing speakers

Cons

• Expensive for its feature-set

The HP E27m G4 has a lot in common with our top pick, the Dell S2722DZ. It’s a little pricier but comes with a few advantages that may give it an edge depending on your needs. The form factor is similar: Both monitors are 27-inch QHD displays with pop-up 5MP webcams: The E27m G4 features larger forward-facing speakers that provide better sound, and even more connectivity options than the Dell, though. It too has a 65W USB-C port, DisplayPort, and HDMI, but also has a whopping four USB-A ports and Ethernet. A monitor is already front and center in your setup: The HP E27m G4 lets it serve as a connectivity hub as well.

Best curved: Philips Brilliance 499P9H

Walmart

SEE IT

Why it made the cut: An ultrawide display designed with productivity in mind, the Philips Brilliance 499P9H is perfect for dual-computer setups.

Specs

• Size: 48.8-inch
• Resolution: 5120 x 1440
• Refresh rate: 70Hz
• Ports: USB-C (65W), DisplayPort, HDMI (2), USB 3.1 (3), Ethernet, 3.5mm audio out
• Panel type: VA
• Webcam: 2-megapixel IR pop-up camera
• Webcam resolution: 1080p

Pros

• Huge display
• Built-in KVM switch
• Plenty of connectivity options

Cons

• Webcam falls short of other monitors
• Hard to find

The Philips Brilliance 499P9H can easily take the place of two standard 27-inch displays. Its curved 49-inch 5120 x 1440 resolution display gives you a huge canvas to work on. A built-in KVM switch also makes it a very strong choice for work-from-home power users who regularly switch between using personal and professional PCs.

At only 2MP, the pop-up webcam on the 499P9H leaves something to be desired. It does, however, support Windows Hello. A 49-inch curved ultrawide monitor won’t be for everyone, but the Philips Brilliance 499P9H is a unique offering and a great fit for the right kind of office workflow optimizer.

Best budget: ​Dell S2422HZ

Dell

SEE IT

Buy it used or refurbished: Amazon

Why it made the cut: An affordable option that doesn’t compromise where it counts, the ​Dell S2422HZ is ideal for anyone with more modest needs or a smaller space.  

Specs

• Size: 24-inch
• Resolution: 1920 x 1080
• Refresh rate: 75Hz
• Ports: USB-C (65W), DisplayPort, HDMI, USB 3.2 (2), 3.5mm audio out
• Panel type: IPS
• Webcam: 5-megapixel IR pop-up camera
• Webcam resolution: 1080p

Pros

• Affordable
• Ample connectivity options
• Full-featured webcam

Cons

• 24-inch display may be small for some

Technically, you can get a cheaper monitor with a built-in webcam than the Dell S2422HZ, but this smaller counterpart to our top pick offers a better all-around value than you’re likely to find in more basic models, at a similar price point. The 24-inch, 1920 x 1080 display has basically all of the same great features as the Dell S2722DZ, including a 5MP pop-up webcam, 5-watt speakers, and USB-C connectivity with 65 watts of laptop-charging power. Dell also offers one of the best warranties around on monitors and includes a Premium Panel Exchange policy that will replace a panel for free if you find even one faulty pixel.

Best for Mac: Apple Studio Display

Bestbuy

SEE IT

Buy it used or refurbished: eBay

Why it made the cut: It’s expensive, and not without issues, but Apple’s Studio Display is an attainable 5K display with all the design flourishes you’d expect from an Apple product.

Specs

• Size: 27-inch
• Resolution: 5120 x 2880
• Refresh rate: 60Hz
• Ports: Thunderbolt 3/USB-C (96W), USB-C (3)
• Panel type: IPS
• Webcam: 12-megapixel fixed camera
• Webcam resolution: 1080p

Pros

• 5K display with great color accuracy
• Impressive sound from built-in speakers
• 12-megapixel webcam with Center Stage support

Cons

• Expensive
• Webcam picture quality issues require an upcoming firmware update

Eagerly anticipated by Mac lovers, the new Apple Studio Display finally delivers on the promise of a high-end monitor made by Apple for its desktop fans and Macbook Pro aficionados. While it isn’t as performant as Apple’s obscenely priced Pro Display XDR, you do get a great 27-inch, 5K display for the money and most of the features you’d expect from a pro-level monitor, including a Thunderbolt 3 port that delivers 96W of power, three USB-C ports, and one of the best speaker systems you’ll find in a monitor. 

Unfortunately, the monitor’s 12MP webcam has been the monitor’s one big point of contention at launch, with a number of reviews finding its performance to be lackluster given the monitor’s hefty price tag. Apple is promising a fix in a future software update, however, and we did find the webcam to still at least be usable in our testing.

What to consider before buying a monitor with a built-in webcam

While the webcam is the distinguishing feature of the monitors in this guide, it does not change the core requirements of what makes for a great monitor. Ultimately, finding a monitor with the right resolution, refresh rate, and other features are all prerequisites for making this list, and you probably shouldn’t compromise on any of them for the sake of a feature that can be easily tacked on for an extra $100 or so.

We have many, many guides on picking specialty monitors—for Macs, color grading, gaming, etc.—so we’ll only cover the basics here. You’ll want to get one that’s the right size for your needs—likely at least a 24- or 27-inch monitor for most people, or even larger for some uses—but don’t compromise on technical performance for the sake of buying bigger. If some features are particularly important to you, like color accuracy for creative professionals or refresh rate for gamers, it’s probably a good idea to broaden your choices and consider monitors both with and without a webcam to see which option makes the most sense for you. 

Monitor specs 101

In order to get the sharpest possible picture, you should treat picking your monitor’s resolution and size as a single decision. Bigger and higher-res always look better, but there’s a sweet spot for getting the best possible picture from a display if you pair the right resolution and size. A 1920 x 1080 (or 1080p) monitor looks great on a 24-inch display, but that same resolution will look noticeably less sharp on a 27-inch display, where a 2560 x 1440 (or QHD resolution) will be a much better fit. Likewise, 4K resolution can also provide a bump in picture quality on a 27-inch display, but starts to feel essential when you move up to a 32-inch monitor, or something even larger.

You’ll also want to pay attention to the monitor’s refresh rate, which controls how often the screen draws and redraws what it shows on-screen. A higher refresh rate makes anything that moves on your screen look more fluid. Whether or not you need a high refresh rate, however, comes down to what you’re doing: Gamers will want to look for a high refresh rate monitor—144 Hz or more (scroll back up and click on our gaming monitors round-up for examples)—while most productivity monitors are 60Hz, which is fine for basic office work, though a slightly higher 75Hz display will make things feel more fluid.

If you specialize in creative work—image and video editing—there are other factors you’ll want to focus on to ensure the most accurate picture, such as color accuracy, which determines just how true the colors you see on the monitor are to real life. There are a number of different standards that different manufacturers use to measure color reproduction. Scroll back up and click through to our round-up on the best monitors for color grading has an explainer if you want to get into the nitty-gritty but, fair warning, it gets very technical, very fast.

What a built-in webcam brings to the table

Webcams built into monitors run the gamut of quality. Some monitors have a tiny webcam built into the bezel just like a laptop. Others have larger pop-up webcams, which can be both more full-featured and flexible. You can conveniently hide them when they’re not needed, and some also let you adjust or tilt the camera to get just the right angle. One of our picks even lets you remove it altogether. 

Larger built-in webcams are generally better. They feature larger lenses that can take in more light, leading to better picture quality. This is especially important for poorly or unevenly lit rooms, where a little light has to go a long way. They’ll also be able to house a sensor supporting more megapixels (MP), another factor contributing to a better broadcast.

Lastly, keep in mind that built-in webcams have utility beyond video conferencing and streaming. For Windows users, we recommend looking for monitors with infrared webcams that support Windows Hello, so you can log into your computer using facial recognition instead of a password.       

Other features to pay attention to

Since the appeal of a monitor with a built-in webcam is all-in-one convenience, most also go one step further and include built-in speakers, as well as a built-in microphone (or often multiple microphones for the best performance). As you’d expect, there is a trade-off in sound quality compared to standalone speakers, but they can often be more than adequate if you’re only watching or listening to the occasional video or podcast, and some of the more premium monitors with built-in speakers can sound surprisingly good. 

If you’re connecting a laptop to your monitor, another way to keep your setup as simple as possible is to look for one with USB-C connectivity. That will let you use a single cable to charge your laptop while it’s connected to the monitor, while your peripherals can remain permanently connected to the monitor USB ports instead of your laptop.

FAQs

Final thoughts on the best monitors with built-in webcams

Given the growing importance of video calls in our hybrid remote lives, one can only assume that a wave of new and exciting monitors with built-in webcams is on the way. For now, the options are still somewhat limited. That said, you don’t need to wait and hope for good options, because there are already a few good ones to choose from.

The beginning of summer is a great time to finally get around to those home projects that have been piling up since November. But to do that, you’ll need the right tools for the job, and DeWalt has you covered if you’re stuck with a rusty, crusty screwdriver or a cheap corded drill with barely any torque. The company has discounted its Cordless Drill / Driver Kit to $99—an $80 discount that makes it accessible to many more people (and, coincidentally, makes it an amazing Father’s Day present).

DeWalt Max Cordless Drill / Driver Kit $99 (Was $179)

DEWALT

SEE IT

We like that DeWalt offers this deal on a full kit instead of just a drill because it will likely be a one-and-done purchase. The company has bundled an extra battery, charger, half-inch drill driver, and carrying case. The only accessory we recommend getting is the company’s 45-piece bit set, which will prepare you for any home repair task. The drill itself has all the features we look for in a tool: power (it rotates up to 1,500 times per second); safety (a locking mechanism); ergonomics (a 3.8-pound weight and grippy handle for easy maneuverability); and thoughtful extras (a front-facing light that shines when the drill is activated). This model is also cordless, meaning you can safely carry it up a ladder or use it in places without an outlet.

Given DeWalt’s reputation and this tool’s power—likely more than you’ll need, but helpful to have when necessary—this is probably the last drill you’ll ever need. The company is confident enough to recommend using it on stone, metal, and wood. Whether you’re attaching new gutters to your home, setting up outdoor security cameras, or want to go overkill when tightening screws on cabinet handles, this drill is up for the task. Just remember to keep at least one battery fully charged, and to store it inside the carrying case when it’s not in use to ensure it lasts a lifetime.

If you’ve got a bone to pick with the way traditional audio devices disconnect you from the world, there is another option: bone-conduction headphones. Headphones, in general, can play many valuable roles, no (or some) bones about it: they let you jam out to music, dive into podcasts, or dial into phone calls while blocking out environmental noise. This can help you concentrate on tasks, but there are some circumstances when being cut off from what’s around you isn’t optimal. The best bone-conduction headphones let you enjoy all your favorite listening experiences with your ear canal exposed so that you can drive, walk, run, bike, swim, etc.—all while remaining completely aware of your surroundings.

Following extensive research, we selected pairs that address the specific needs of athletics, work environments, and age. We chose units that were easy to use, incorporated the features we love about traditional headphones, and prioritized sound quality.

The best bone-conduction headphones: Reviews & Recommendations

Sitting right outside the ear on the jaw, bone-conduction headphones are a different physical and acoustic experience than most people are used to. But different can be good. Here are our picks for the best bone-conduction headphones to help keep you in the hear and now.

Best overall: Shokz OpenRun

SHOKZ

SEE IT

Why it made the cut: Shokz is dedicated to producing top-tier bone-conducting headphones, and the OpenRun is the company’s most advanced model, employing eight-generation technology to boost sound quality.

Specs

• Frequency response: 20Hz-20KHz
• Battery life: 8 hours
• Charge time: 2 hours

Without a doubt, Shokz has cornered the bone-conduction headphone market. The company produces thoughtfully engineered, top-quality products, creating an audio experience to complement the activities you enjoy. The OpenRun (formerly the AfterShokz Aeropex) is an excellent pair of bone-conduction headphones overall. Available in four colors and two band sizes, the OpenRun fits gently, yet securely, around the back of the head, looping around the ears and resting against the temples. The headphones employ patented eight-generation bone-conduction technology, are equipped with Bluetooth 5.0 SBC, and feature PremiumPitch 2.0+ signal processing, which prevents bleed, minimizes distortion, and produces a more dynamic bass with minimal vibrations. The battery lasts eight hours, and each pair comes with two magnetic USB charging cables, which can provide a full charge in just two hours. A dual noise-canceling mic will let you make clear calls, and included earplugs can help you tune things out when the time is right. An IP67 rating means this pair can withstand dirt, dust, sweat, and rain, while a built-in moisture detector will let you know when it’s getting wet. However, while the OpenRun is water-resistant, it’s not designed to be fully submerged in the pool.

Best waterproof: Shokz OpenSwim

SHOKZ

SEE IT

Why it made the cut: The OpenSwim have an IP68 rating, which means they can be fully submerged in water for up to two hours; you can swim with them without making terrible sacrifices regarding audio quality.

They even come with a noseclip.

Best for calls: Shokz OpenComm

SHOKZ

SEE IT

Specs

• Frequency response: 20Hz-20KHz

The OpenComm system also lets you bypass your car’s choppy stereo if you have to make a call on the road, without cutting yourself off from the sound of traffic. You can also stay on the call when you’re at a job site or keep connected during a busy commute, all without losing situational awareness. You can get up to 16 hours of talk time or 8 hours of listening, and with Quick Charge, you’ll get a replenished two hours of battery life in just five minutes.

What to consider when buying the best bone-conduction headphones

If your mom always warns you not to listen to your headphones while walking home at night, or you need to hear the traffic behind you as you pedal to work, try out the best bone-conduction headphones. To determine which pair will work best for your needs, you’ll want to consider where and when you’ll be using them the most. You’ll also want to make sure you understand how they work, especially if this is your first pair of bone-conduction headphones.

First of all, what is bone conduction, and how does it work?

Bone-conduction headphones allow you to experience audio sans any direct interaction with your ear canal or eardrum. While this may sound like some new-fangled, tech-heavy sorcery, there is evidence that bone conduction has been around for centuries. It is rumored that Beethoven relied on bone conduction to compose music after losing his hearing by attaching a metal rod to his piano and biting down on it as he played. But how does it work? 

Typically, sound waves travel through the air and are funneled through the ear canal to the eardrums, where they are then decoded into vibrations and sent to the inner ear (or cochlea), which is connected to the auditory nerve. When the vibrations hit the inner ear fluid, tiny hair cells start to convulse, creating electrical pulses that travel up the auditory nerve to the brain. This process is called air conduction. Bone conduction completely avoids the eardrum and relies on a transducer—like headphones, or a metal conductor’s rod in Beethoven’s case—to convert sound waves into vibrations and send those through the facial bones to be received by the inner ear. Essentially, the vibrations received by the cochlea are the same no matter which way you receive them; they are simply sent via a different pathway. 

This concept has even been used in reverse. The Sony WF-1000XM4 earphones include a bone-conduction sensor that picks up the vibrations from your voice during calls to help enable clearer speech without picking up ambient sound.

Who should use bone-conduction headphones?

Medically, the best bone-conduction headphones benefit those experiencing conductive hearing loss, a condition that directly affects the transmission of sound through the eardrums. Conductive hearing loss is just one way the auditory system can be disrupted, so bone-conduction headphones won’t work for everyone with hearing difficulties. 

Bone-conduction headphones are also helpful for those who need to maintain situational awareness while they enjoy their music. These headphones provide an additional layer of safety for bikers, hikers, drivers—essentially anyone who needs to be aware of their surroundings. Active in dense urban environments? Bone conduction makes for great running headphones. Bone-conduction headphones are also particularly great for swimmers. Air conduction is heavily suppressed when we are underwater, but the vibrations created by bone conduction can still be transmitted, which means a pair of bone-conduction headphones with an Ingress Protection rating of IP68 (a.k.a. waterproof) can keep you connected to your workout playlist lap after lap. 

Now, bone conduction won’t make your entire face shake, rattle, and roll, so you don’t need to worry about experiencing discomfort while you listen. In fact, many report that these headphones are secure, comfortable, and easy to wear. However, if you are sensitive to pressure, there is a chance that you may experience dizziness or headaches after a long stretch of listening.

How’s the sound quality?

If you’re an audiophile searching for your next pair of headphones, chances are bone conduction isn’t going to be what you’re looking for. That being said, the overall audio quality of these headsets can certainly get you through a tough training session or walk to work. At high volumes, audio can start to distort or get crunchy and an expansive mix isn’t really possible. However, with a quality model, you will still get to experience impactful bass; you’ll feel the vibrations instead of highly pressurized waves from over-ear cans. 

Just remember that even the best bone-conduction headphones aren’t meant to fit or even necessarily sound like traditional headphones or earbuds. If you haven’t used bone-conduction headphones before, you might feel inclined to turn up the volume as loud as it can go in an attempt to recreate that natural, passive noise cancellation that every other type of headphone relies on. Remember that nothing is blocking your ear canal, which means that you will purposefully be able to hear your surroundings clearly; maxing out the volume won’t affect that, but it could lead to hearing loss down the road.

Can bone-conduction headphones use Bluetooth?

Yes, there are wireless bone-conduction headphones that use Bluetooth 4.2 and higher to connect to smart devices such as cellphones and computers. Set up and pairing is no different with Bluetooth bone-conduction headphones than connecting any other type of Bluetooth headphones, and some may even have onboard controls like play, pause, and skip for your streaming services. Other models are more like a portable MP3 player, with the ability to store hours of songs internally that you can then play through without any wires involved. Remember the iPod shuffle? That’s what you’ll be getting—an excellent option for folks who want to jam out to a curated playlist while they focus on working out or a walk about the town.

Can you take phone calls with bone-conduction headphones?

Yes, some bone-conduction headphones are equipped with a microphone so you can answer calls on the go. While the headphones themselves can’t employ any passive or active noise cancellation to enhance your listening experience, some models can use technology to make calls crisp and clear. The headphones with mic use various means to minimize outside sound—like wind, traffic, etc.—ensuring that the person you’re talking to can hear you without interruption. Just remember that bone-conduction headphones are subject to more sound bleed than traditional units, so you’ll want to be conscientious about volume when it comes to private calls.

The fictional and deadly Jurassic Park has nothing on the real-life Dinosaur Cove on the southern tip of Victoria, Australia. Using bones from the fossil-filled hotspot, a team of paleontologists have confirmed that pterosaurs—more commonly known as pterodactyls—flew over Australian skies as far back as 107 million years ago. Their findings are detailed in a study published May 31 in the journal History Biology.

[Related: This pterosaur ancestor was a tiny, flightless dog-like dinosaur.]

The team examined two pieces of prehistoric bone that were extracted from Dinosaur Cove over 30 years ago. The bones belonged to two different pterosaurs, and were examined by experts from Curtin University in Perth and Melbourne’s Museums Victoria. A partial pelvis bone belonged to a pterosaur with a wingspan over 6.5 feet, and the smaller wing bone belonged to a juvenile pterosaur. These bones turned out to be the oldest remains of the giant winged reptiles ever recovered in Australia, which is better known for its larger sauropod fossils. 

Closely related to dinosaurs, pterosaurs soared through the skies during the Mesozoic Era, about 252 million years ago.

“During the Cretaceous Period (145–66 million years ago), Australia was further south than it is today, and the state of Victoria was within the polar circle—covered in darkness for weeks on end during the winter. Despite these seasonally harsh conditions, it is clear that pterosaurs found a way to survive and thrive,” study co-author and Curtin University PhD student Adele Pentland said in a statement. 

According to Pentland, remains of pterosaurs are a rare find worldwide. Even fewer remains have been discovered at regions that were once high paleolatitude locations, including Victoria. She told CNN that less than 25 sets of pterosaur remains from four species have been found in Australia since the 1980s, compared to more than 100 sets in countries like Argentina and Brazil.  

“So these bones give us a better idea as to where pterosaurs lived and how big they were. By analyzing these bones, we have also been able to confirm the existence of the first ever Australian juvenile pterosaur, which resided in the Victorian forests around 107 million years ago,” said Pentland.

The specimens were found in the 1980s in a Dinosaur Cove expedition led by paleontologists Tom Rich and Pat Vickers-Rich. Their discovery of big-eyed dinosaurs along this area of coastline helped spark a major shift in how dinosaurs were more generally perceived. These “dinosaurs of darkness” gave paleontologists a glimpse of survival without sunlight and reframed questions about whether dinosaurs were warm-blooded creatures. 

“These two fossils were the outcome of a labor-intensive effort by more than 100 volunteers over a decade,” Tom Rich said in a statement. “That effort involved excavating more than 60 meters [196 feet] of tunnel where the two fossils were found in a seaside cliff at Dinosaur Cove.”

The biggest pterosaur scientists know of so far is Quetzalcoatlus northropi, which was found in Texas. Since everything is bigger in Texas, this pterosaur had a wingspan of about 32 to 36 feet. Australia’s largest pterosaur is the Thapunngaka shawi. It was discovered in 2021 by a team from the University of Queensland and boasts a wingspan of roughly 22 feet.

No matter your operating system, Mozilla Firefox makes a great default browser. The free program is quick, intuitive, and packed with features. And you can customize it in all kinds of ways, from tweaking the look of the software to changing the appearances of individual websites.

Once you dig past the surface-level options, you’ll find you can do even more with this privacy-focused browser. These features include app troubleshooting, expert tab management, and entirely new ways of surfing the web. Check out the tips below to ensure you’re taking advantage of all Firefox has to offer.

1. See tabs on your other devices

If you’re using Firefox on multiple devices—maybe a laptop, a desktop, and a phone—and you’re signed into the same Firefox account on all of them, you can see open tabs across all of them through a feature called Firefox View.

First, click the three horizontal lines (top right), then Settings and Sync to make sure you’re signed in. As long as you’re signed in on at least one other device, you can click the Firefox icon on the far left end of the tab bar to see the tabs you’ve got open elsewhere.

2. Customize your address bar

You can turn the Firefox navigation bar into a search powerhouse. That way, when you type keywords (rather than URLs) into the address bar, you’ll be searching for those terms across the web. First, choose the search engine you prefer, whether that’s Google, Bing, DuckDuckGo, or something else. Then set it as Firefox’s default, so search terms in the navigation bar will yield results from that search engine. To do so, open the application menu (click the three horizontal lines on the top right of the page), then choose Settings and Search to set the default.

The address bar can act as more than a standard search engine, too. By typing in special keywords, you can launch custom searches within pretty much any site you like, including Wikipedia, IMDb, Amazon, and more. To set this up, navigate to the site you want to search and find its search box. Right-click inside the box and choose Add a Keyword for this Search. A dialog box will pop up. Next, type something short but unusual in the keyword box. This is the term that will trigger your site-specific search when you type it in the Firefox address bar, so you don’t want it to resemble any normal keywords you might search for on a regular basis. For example, you might choose to trigger an IMDb search with the term “imdb”, because you’re not likely to run a general search for that word.

Click Save, and you can then search within that site by entering your keyword, followed by your search terms, in the address bar at the top of the browser. To stick with our previous example, type “imdb Tom Cruise” into the navigation bar to search the IMDb website for Tom Cruise.

3. Watch videos in picture-in-picture mode

When you’re watching a video in Firefox, you’ll see a small overlay button that looks like two rectangles with an arrow pointing from one to the other. Click on this, and your video will pop out of Firefox. Then, you can carry on browsing while the video continues to play.

Click and drag the pop-up window to move it, and drag in (or out) from its edges to resize it. Click the X to close the picture-in-picture video, or the back to tab button (an arrow pointing to a box) to continue playback inside Firefox again.

4. Delete browsing data when Firefox is closed

Keeping on top of cookies and other browsing data saved by the sites you visit in Firefox can be tricky. This data saves information such as your location and your settings for particular sites, and while it can streamline your browsing experience, you may not feel comfortable with websites knowing this much about you.

If you’d like to stay a little more private, click the three horizontal lines (top right) in Firefox, then choose Settings and Privacy & Security. There, you can check the box labeled Delete cookies and site data when Firefox is closed. Every time you shut down the browser, these files will be automatically wiped, so you won’t need to worry about them.

5. Turn on mouse gestures

Clicking and scrolling is fine, but Firefox lets you supercharge your online navigation with mouse gestures that allow you to trigger specific actions by moving your mouse a certain way. Give it a trial run, with the help of the Gesturefy add-on, and there’s a good chance you’ll never look back.

First, install the extension inside Firefox and restart your browser. To explore the available gestures, open the main menu (the three horizontal lines in the top right) and choose Add-ons and themes. Find Gesturefy, click the three dots next to it, then Options, and you’ll find the configuration panel.

Under the Settings tab, you can set the trigger button, which is a button you need to hold down while making a mouse gesture. Gesturefy’s default trigger is the right mouse button, but you can change it if you’d like. Switch to the Gestures tab to see some of the gestures already in place. For example, dragging the mouse quickly to the right, then the left (with the right mouse button held down) closes the current tab. You can add more gestures to the extension’s repertoire here, too.

It may take you some time to get the hang of these gestures, but once you do, you may find that a quick hand movement feels much more intuitive than fishing around for toolbar buttons or scrolling through menus.

6. Manage your tabs

Tabs make up the core of your browsing experience—but you don’t have to settle for the default options Firefox gives you. Check out the Tree Style Tab extension, for example, which introduces a new tab panel on the left and lets you organize your open tabs into hierarchies, almost like a family tree.

Then there’s Tab Stash: This extension lets you save batches of tabs together as bookmarks inside Firefox. If you’re researching a particular topic, for example, and want to come back to it later, you can quickly save all your open tabs as a group that you can open up again later.

You should also check out Simple Tab Groups. This extension does exactly what its name suggests, enabling you to organize open Firefox tabs into color-coded groups in—you could have one group for work stuff and another for personal stuff, or whatever you like.

7. Take screenshots of webpages

There are all kinds of reasons you might want to take screenshots—for posterity, or maybe to refer to in a separate document—and this is really easy to do in Firefox. Just right-click on a blank part of a page, then choose Take Screenshot. You can either click on an element (like an image) to grab it, click and drag across a region to capture, click Save full page to screenshot the entire page, or click Save visible to just capture what you can currently see on screen.

8. Snooze tabs for later

You might be familiar with snoozing your alarm—hitting a button to postpone your wakeup call and sleep for a few extra minutes. Now you can do the same with Firefox tabs, thanks to a third-party extension called Snooze Tabs.

The extension is pretty simple to use: Click the extension button on the toolbar (it looks like a jigsaw piece), then pick Snooze Tabs. You can send the tab you’re currently viewing, or all your Firefox tabs away until a later time and date—choose a preset option like Tomorrow morning or specify your own with Custom time.

9. Search through your tabs

Browser tabs seem to multiply like magic, and you likely have dozens of them open at any one time. That can make navigation tricky, but there is a tab search trick that can help: Click inside the address bar at the top of the Firefox interface, then type the percentage symbol (%)and a space. You’ll then be able to search through the titles of the tabs that you currently have open.

10. Refresh Firefox

If you find your software bogged down with a bunch of extensions, or behaving sluggishly for no specific reason, most programs require that you uninstall and reinstall them to restore their factory settings. Firefox offers a built-in refresh feature that easily resets the browser back to its factory settings and gets it running as good as new. As Mozilla explains, a refresh will return most Firefox settings back to their default state, but it won’t affect your saved bookmarks, stored passwords, browsing history, or even open windows. What it does scrub are third-party extensions, website permissions, modified user preferences, and any customizations you’ve made to the Firefox toolbar.

To access the refresh feature, type “about:support” into the address bar and hit Enter. This takes you to the master troubleshooting page. Click the Refresh Firefox button on the right, and instructions will guide you through the short process.

If you’re really having problems with Firefox, you may not be able to start it at all, which will prevent you from performing a refresh. So try running it in Troubleshoot Mode, which disables everything except the core Firefox program. To open the browser in Troubleshoot Mode, hold down the Shift button (Windows) or the Option button (macOS) while clicking or double-clicking the program icon. As Firefox starts, you’ll see the Troubleshoot Mode window appear. You can continue to browse in Troubleshoot Mode, or go ahead and run that refresh right away.

11. Switch to dark mode

Firefox comes with its own dark mode, which you may prefer. Click the three horizontal lines in the top right, then pick Settings. Open the General tab, and you’ll find Dark under the Web site appearance heading. This will be applied to Firefox’s own settings and new tab screens, but will only darken a website if the site has been coded to respond to a dark mode request from the browser.

BEING SORE SUCKS. Anyone who’s exercised to an extent can probably complain about the stiffness, pains, or—worse—injuries the next day. But as annoying as the achiness gets, it’s a critical part of the recovery process. 

Under your skin, the all-important muscle fibers that push and pull bones to move you around tear slightly during a workout—a phenomenon called microtrauma. Combined with inflammation, these tiny ruptures may cause soreness, which your body alleviates by replacing the cells around the wound.

There are actually two kinds of muscular soreness that you feel after a workout, and they come from different sources. The microtrauma-based discomfort is known as DOMS, short for delayed-onset muscle soreness. You might feel it most between 24 and 48 hours after the workout—and for as long as three to five days. The other type, acute muscle pain, happens after you overwork your body. These pangs go away in about a day or two, just in time for the DOMS to peak. 

So are there surefire ways to get rid of your soreness? Not exactly. The problem is that to ease the aches, your body has to heal the microtears, which isn’t a process you can speed up. There is some good news, though: A solid post-workout ritual could have a placebo-like effect on your mind, blunting some of the pain you feel. And there could be other perks too.

For example, stretching does not lead to faster recovery, but it does make you more flexible and less prone to injury in the future, especially during high-intensity workouts. And while warm-ups don’t help with the healing process either, they do raise your heart rate, preparing you for the sudden jump in activity. 

Then there are the various salves, tools, and self-care schemes people try. A few studies show that proper use of compression gear could confer some benefits for blood flow and enzyme production. Some gymgoers pregame the pain with anti-inflammatory drugs like aspirin and ibuprofen, though they have no proven power against soreness. Elite swimmers might tolerate the bruises that come with cupping therapy—without any science to confirm the benefits of the practice. Even ice baths and far-infrared saunas (featuring high heat and low humidity) have minor, inconsistent results, according to researchers.

In general, getting a massage a day or two after a workout offers short-term relief for muscle tenderness. You will likely feel a little worse with a pair of hands or a percussive therapy device kneading into you, but as soon as it’s done, your pain will be more manageable for the next few hours. In certain circumstances, massages might even help reduce inflammation and DOMS.

There are three surefire things you can do, however, to soothe your soreness a bit. The first is to rest. Your body needs time to rebuild your muscle fibers, so getting a good night’s sleep and using the sore body parts less when you’re awake will help you recover faster. Weightlifters know this well and will work a different muscle group each session. If you’re a regular at the gym, commit to triceps one day and focus on a different group (biceps, maybe) the next.

The second is to make sure you’re eating well. Your body requires nutrients like proteins and carbohydrates to patch up your muscles, so enjoy a big bowl of pasta or a tall glass of chocolate milk a few hours after training. 

The third thing you can do is keep at it. DOMS hits harder when you try a new form of exercise because your body is not used to the strenuous activity. The first time will always be the most painful. But if you set a schedule and habit around the workouts you like best, it should hurt less after you crush all your reps.

The race to electrify the world’s vehicles and store energy will require batteries — so many of them, in fact, that meeting the demand we will see by 2040 will require 30 times the amount of critical minerals like lithium, cobalt, and nickel that those industries currently use.

That presents an enormous challenge, one exacerbated by the mining industry’s alarming allegations of labor crimes, environmental destruction, and encroachments on Indigenous land. There are ways to mitigate electrification’s extractive impacts, one of which may seem obvious: Recycle every battery we make. 

Doing so would reduce the world’s need to mine these minerals by 10 percent within 16 years, because the critical materials in batteries are infinitely reusable. Eventually, a robust circular battery economy could all but eliminate the need to extract them at all.

Of course, that would require recovering every EV pack at the end of its life, a sizable undertaking as the United States prepares for hundreds of thousands of electric vehicles to retire by the end of the decade. A nascent ecosystem of startups is working toward that goal, and the Inflation Reduction Act includes tax credits to incentivize the practice. But some electrification advocates say those steps do not go far enough. While the European Union recently passed a regulation mandating EV battery recycling, there is no such law in the U.S. Proponents of a federal recycling standard say that without one, batteries that could be recycled might get left behind, increasing the need for mining and undermining electrification’s environmental benefits. 

“We need a coordinated federal response to truly have a large-scale impact on meeting our demand,” said Blaine Miller-McFeeley, a policy advocate at Earthjustice, which favors a federal recycling requirement. “If you compare us to the EU, we are woefully behind and need to move much more quickly.”

That movement would have to come from Congress, according to Miller-McFeeley. Historically, however, regulating recycling has been left up to the states and local jurisdictions. The Biden administration has instead been supporting the country’s budding EV battery recycling industry, mainly by making it good business to recover critical materials. 

The Department of Energy wants to establish a “battery ecosystem” that can recover 90 percent of spent lithium batteries by 2030. It has granted billions in loans to battery recyclers to build new facilities. Automakers are incentivized to buy those recyclers’ products, because part of the federal EV tax credit applies only to cars with batteries that include a minimum amount of critical minerals that were mined, processed or recycled in the U.S. or by a free-trade partner. Manufacturers also get a tax credit for producing critical materials (including recycled ones) in the U.S.

Daniel Zotos, who handles public advocacy at the battery recycling startup Redwood Materials, said in an email that a healthy market for recycled materials is emerging. “Not only is there tremendous value today in recycling these metals, but the global demand for metals means that automakers need to source both more mined and recycled critical minerals.”

Zotos said Redwood Materials agrees with the approach the federal government has taken. “The U.S. has in fact chosen to help incentivize, rather than mandate, recycling through provisions established in the Inflation Reduction Act, which we’re deeply supportive of.”

During a pilot project in California last year, the company recovered 95 percent of the critical materials in 1,300 lithium-ion and nickel metal hydride EV and hybrid batteries. The cost of retrieving packs from throughout the state was the biggest barrier to profitability, but Zotos said that expense will subside as the industry grows.

A tiny but growing secondary market for EV batteries is also driving their reuse. Most batteries will be retired once their capacity dwindles to about 70 to 80 percent, due to the impact on the car’s range. But they’re still viable enough at that point to sustain a second life as storage for renewable energy like wind and solar power. 

B2U Storage Solutions used 1,300 retired batteries from Nissan and Honda to create 27 megawatts hours of storage at its solar farm just north of Los Angeles in Lancaster, California. Photovoltaic panels charge the packs all day, and B2U sells the stored power to the local utility during peak demand in the evening. “There is more value in reuse,” said company president Freeman Hall, “and we’re not doing anything more than deferring recycling another four or five years.” 

Homeowners and hobbyists are embracing second-life batteries, too. Henry Newman, co-owner of the auto dismantler EV Parts Solutions in Phoenix, said customers buy his Tesla and Nissan Leaf batteries to convert classic cars or create DIY power storage at home. Any batteries that Newman can’t sell are picked up by Li-Cycle, a lithium-ion battery recycler with a plant in Gilbert, Arizona. 

Newman said dismantlers and customers seem to want to do the right thing. “I know there will be people who don’t follow regulation, but my experience in the last six to seven years is that the industry is pretty conscious of it and tries to mitigate throwing these things in the trash,” he said. A law could help prevent mishandling, but Newman worries about any overreach or added costs that would come with more regulation. 

But relying on the market to ensure proper stewardship is risky, said Jessica Dunn, a senior analyst in the clean transportation program at the Union of Concerned Scientists. “The recycling of cars has traditionally been a market-based environment,” she said. “But we’re dealing with a completely different system now. EV batteries are big and have a lot of critical materials in them that we need to get out of them no matter if it’s economical or not.” 

Transporting EV batteries, which can weigh more than 1,500 pounds, is expensive (as much as one-third of the cost of recycling them), dangerous, and logistically challenging. Packs can catch fire if improperly handled, and they are classified as hazardous material, which requires special shipping permits. If the battery is in a remote location or is damaged, a recycler could deem it too much trouble to retrieve without a mandate to do so.

Dunn also said that not all batteries contain enough valuable materials for it to make financial sense to go through the trouble of recovering them. While most EV batteries currently contain high-value cobalt and nickel, a new generation of cheaper lithium-ion-phosphate, or LFP, batteries don’t use those metals. Tesla, Ford, and Rivian all recently announced they will use LFPs in some models.

“Just because there aren’t nickel and cobalt in them doesn’t mean that the lithium isn’t something that we should be recovering,” said Dunn. Redwood Materials said it collects lithium-ion phosphate batteries and uses the lithium within them to assemble new battery components, and that they collect all battery packs no matter their condition.

Finally, without guidelines in place, viable batteries may not be repurposed before being recycled, which Dunn said undermines their sustainability. “You’ve already put all that literal energy — and the environmental impacts that go along with that — into manufacturing these batteries,” she said. “So if you can squeak an extra five to 10 years out of them, that’s a really good option.” 

With the U.S. poised to see about 165,000 electric vehicle batteries retire in 2030, Dunn said the time to ensure no batteries are stranded is now. “We’re not seeing a big wave now, but that’s coming, and so we need to be prepared for that.”

There has been some federal movement toward a recycling requirement. The 2021 bipartisan Infrastructure Investment and Jobs Act directed the Department of Energy to establish a task force to develop an “extended battery producer responsibility framework” to address battery design, transport, and recycling.

Extended producer responsibility, or EPR, is the approach that the EU took in its battery regulation that passed last December. EPR puts the onus on the manufacturer to ensure that what they produce is properly repurposed and then recycled, either by compelling them to pay for the recycling or to handle it themselves. 

Thirty-three states have such laws, covering 16 products ranging from mattresses to packaging. “It is a paradigm shift for how waste is managed in the United States,” said Scott Cassel of the Product Stewardship Institute. But Congress has never passed such a law. 

EV battery recycling might be the issue that could garner bipartisan support for one. Access to critical materials is a foreign policy and national security issue: China processes more than half the world’s lithium and cobalt, which means a steady domestic supply from recycling would help alleviate dependency on a geopolitical rival. 

Building out the infrastructure to dismantle, recover, and process battery materials could also create thousands of jobs, an accomplishment most lawmakers are happy to align themselves with.  

Republican senators alluded to both benefits when supporting the bipartisan Strategic EV Management Act of 2022, which passed as part of the National Defense Authorization Act last year. It requires multiple agencies to work on guidelines for “reusing and recycling” batteries from vehicles retired from the federal fleet. 

Republican Senator Bill Hagerty of Tennessee said in a statement that the bill would ensure agencies could “reap the full economic benefits of EV investments … and do so in a manner that lessens our dependence on communist China.” 

These laws set in motion efforts to design recycling frameworks, but the timelines to develop them span years. In the meantime, a few states are weighing their own mandates. “The states don’t want to wait for any of these bills to move,” Cassel said. “They’re ready to act right now.”

In California, a Senate bill would require battery suppliers to ensure that all “vehicle traction batteries” be recovered, reused, repurposed, or recycled. The bill passed unanimously this week and is headed to the Assembly. Senator Ben Allen, who introduced the bill, said there is bipartisan political and industry support for creating a framework. “You need a system in place,” he said. “That’s like saying, ‘Oh, the people will drive just fine to and from work. We don’t need traffic laws.’” 

As it has been with other clean-vehicle targets, California could be a bellwether for a standard that would eventually take hold nationally.

“We’d love to create a system that could help to inform national policy,” said Allen. “And in this case, with this industry support and bipartisan backing, there actually may be a blueprint here.”

Atlantic hurricane season officially begins on June 1—and a disturbance in the Gulf of Mexico is already brewing. Tropical wave Invest 91-L only now has a 70 percent chance of becoming the first named system of the 2023 Atlantic hurricane season—Arlene—but it will likely bring downpours and gusty thunderstorms to parts of Florida by the end of the work week whether or not it becomes a named storm.

[Related: What hurricane categories mean, and why we use them.]

For the 2023 season, NOAA forecasts a pretty average amount of hurricane activity. In their annual outlook, NOAA predicts a 40 percent chance of a “near-normal season”, a 30 percent chance of an “above-normal season”, and a 30 percent chance of a “below-normal season”. 

The forecast calls for 12 to 17 total named storms—those with winds of 39 MPH or higher. NOAA anticipates that five to nine of these storms could become hurricanes (winds of 74 MPH or higher), including one to four major hurricanes. Major hurricanes are category 3, 4, or 5 storms with 111 MPH winds or higher.

Some of the names for this year’s storms include Cindy, Harold, and Sean among others.

The 2023 season is anticipated to be less active than recent years, partially due to a tug-of-war between some factors that suppress storm development and some that fuel it. This is the first year in three years without a La Niña pattern present, and the latest forecasts say there is a 90 percent likelihood that El Niño will develop by August and then remain strong in the fall. 

El Niño’s influence on storm development may be offset by favorable conditions in the tropical Atlantic Basin. Those conditions include a potentially above-normal West African monsoon that helps create some of the Atlantic’s stronger and longer-lived storms, all while creating  warmer-than-normal sea surface temperatures in the Caribbean Sea and tropical Atlantic Ocean. 

These warm waters are pure hurricane fuel, and those temperatures have been incredibly high this spring. But the temperatures in the North Atlantic basin, where the storms are born and intensify, and the eastern-central tropical Pacific Ocean, where El Niño forms, are the places to watch.

“This year, the two are in conflict—and likely to exert counteracting influences on the crucial conditions that can make or break an Atlantic hurricane season,” Iowa State University atmospheric scientist Christina Patricola writes in The Conversation. “The result could be good news for the Caribbean and Atlantic coasts: a near-average hurricane season. But forecasters are warning that that hurricane forecast hinges on El Niño panning out.”

[Related: El Niño is probably back—here’s what that means.]

Ocean temperatures in the Atlantic’s tropical regions were unusually warm during the most recent active hurricane seasons. In 2020, the Atlantic produced a record 30 named storms and the 2005 season produced 15 hurricanes including Hurricane Katrina.

The tropical Pacific Ocean influences the Atlantic hurricanes by forming teleconnections—a chain of processes that change the ocean or atmosphere in one region which then leads to larger scale changes that can influence the weather in other places.

“During El Niño events, the warm upper-ocean temperatures change the vertical and east-west atmospheric circulation in the tropics,” Patricola writes. “That initiates a teleconnection by affecting the east-west winds in the upper atmosphere throughout the tropics, ultimately resulting in stronger vertical wind shear in the Atlantic basin. That wind shear can tamp down hurricanes.”

Atlantic hurricane season ends on November 30. In the meantime, NOAA encourages those who could be affected by tropical systems to understand watches and warnings for their area and prepare emergency supplies ahead of time.

Love it or hate it, sleeping naked hits different. Not only is it less laundry to wash, but taking off those pajamas can do wonders for your health. While you may feel self-conscious at first, the openness of resting in the nude can actually boost your confidence and help you look your best self. 

There’s no right or wrong way to get ready for bed—it’s all a matter of preference. And while nakedness won’t miraculously cure all your sleep problems, experts say there are some modest benefits to going au naturel.

1. Younger-looking skin 

James Walker, a medical advisor for the healthcare platform Welzo, says sleeping without clothes gives your skin an opportunity to breathe, allowing for better airflow. He explains that clothes, especially tight-fitting ones, can restrict blood circulation, making it harder for your skin to receive vitamins and minerals needed for collagen production. Certain materials also might add to your discomfort in bed. Aditya Kashyap Mishra, a sex educator and relationship expert for Lustyboy, says synthetic fibers like spandex and nylon trap moisture in your skin—the added heat can make it hard to fall asleep. Other synthetic fabrics and pajamas with dyed cotton may cause skin irritation and acne from the fabric rubbing against you.

[Related: 5 surprising beauty benefits of running]

Tossing and turning from wearing the wrong clothing can affect your quality of sleep and your skin. The body makes collagen during sleep, which is essential for supple and younger-looking skin. Research shows that getting less than the recommended seven hours of sleep for adults increases skin aging and slows down recovery from sun damage.

2. A cooldown for your body

As you might expect, sleeping with your skin exposed helps regulate your temperature at night, says Walker. The drop in body temperature can prevent overheating—a real concern in summer and in places where winter is virtually non-existent. Research shows that feeling extremely hot at night increases wakefulness. Even if you manage to land some shut-eye, it will likely be less restorative with shorter cycles of slow-wave sleep and REM sleep. 

Feeling colder, on the other hand, can also help you fall asleep faster. Your body temperature is synced up with the light-dark cycles outside; it normally falls when the sun goes down. A lower body temperature from sleeping nude tells your biological clock it’s time to shut down.

3. Fewer fungal infections

Fungi and bacteria thrive in warm and damp areas like your nether regions. Mishra explains that trapped sweat from moisture-wicking clothing increases the risk of microorganisms building up, resulting in yeast infections and jock itch. Jock itch can also come from constant friction from clothes. Stripping down to nothing will allow more air circulation and keep your intimate parts from getting overheated.

4. Better emotional intimacy

Skin-to-skin contact between partners can strengthen your relationship. Research shows touching among consenting adults releases the “love hormone” called oxytocin. This chemical reduces stress and encourages openness and social bonding with others. One US marketing poll of more than 1,000 adults found that 57 percent of couples who regularly snoozed in the nude were happy in their relationship compared to 48 percent of pajama wearers. Getting used to baring it all in front of a partner can counteract self-consciousness of how you look in bed. Mishra says this openness is a huge stress reliever, and the added relaxation can help you sleep better.

What if you want to sleep in clothes?

If you’re still not convinced about sleeping naked, there are other ways to improve your slumber. Avoid tight or constricting apparel that would restrict your movement, irritate your skin, or otherwise cause discomfort. Walker recommends going to bed in loose-fitting and breathable fabrics like cotton or bamboo, or one simple layer like an oversized T-shirt and shorts to avoid overheating.

There’s nothing wrong with slipping on a pair of socks before bed, Walker adds. Some people find it comforting and helpful in keeping their feet warm, especially during colder seasons. However, he warns against sleeping in socks that are too tight as they could restrict circulation. 

Whether you go to bed nude or in clothes, you should always remove your makeup and any heavy jewelry. Snoozing with makeup on can clog pores and lead to future breakouts. “It’s best to cleanse the face thoroughly before sleeping to allow the skin to breathe and regenerate,” advises Walker. Additionally, laying down in chunky necklaces, bangles, and other jewelry can be painful and might even leave abrasions on the skin.

“Ultimately, the key is to prioritize comfort and choose sleepwear that allows for optimal relaxation,” Walker says. “It’s always a good idea to listen to your body and make choices that help you feel comfortable and at ease during sleep.”

Out in the Atlantic Ocean, roughly 100 kilometers off the northwest coast of Africa, lies an archipelago known as the Canary Islands, created millions of years ago by intense volcanic activity. The biggest and most populated island, Tenerife, rises from the deep-ocean floor to a series of peaks, one of which is the third-largest volcano in the world. Tenerife’s interior highlands are a moonscape, while its coastline of lava rock and sheer cliffs is pounded by surf. In contrast to most of the island’s stark geology, north of the island’s capital, Santa Cruz, is a long crescent-shaped beach of soft yellow sand, with groves of palm trees and a calm bay created by a long breakwater. This is Playa de las Teresitas, a magnet for northern European tourists craving winter sun.

But most of the people sunbathing on Teresitas are likely unaware of what lurks in the shallow waters lapping the shoreline. The bay—engineered and less than 10 kilometers from the Canaries’ second-largest city—is a surprising haven for pups of one of the world’s most critically endangered fish: the angelshark.

When the Spanish took control of the Canaries in the 1400s, they began cultivating cash crops: cochineal and sugar cane in the beginning, and later adding bananas, tomatoes, and other valuable commodities. For centuries, the islands’ economy thrived, but it was a fragile wealth. Over the years, livelihoods were threatened by cycles of crop disease, competition from cheaper markets, and lava flows that wiped out harvests and turned good agricultural land into barren terrain. In the 1950s, the boom in package tourism showed promise as a new cash crop. But while the islands had the sunshine, warm climate, and ease of access from Europe needed for this new industry, they were missing a vital element: picture-postcard sandy beaches.

Cue planners on Tenerife, who concocted an audacious plan to make over one of the island’s exposed lava-rock beaches. They chose a stretch of coastline close to Santa Cruz and expropriated the avocado farms and other smallholdings. Earthmovers leveled the foreshore and intertidal zone, and they constructed a breakwater over a kilometer long. And then, from the Western Sahara on Africa’s northwest coast, they shipped in the pièce de résistance: 240,000 tonnes of sand.

By 1973, this gargantuan project, environmentally questionable from today’s viewpoint, was complete. As anticipated, tourists arrived. Unanticipated was what their presence gave to one of the world’s most endangered fish species—visibility. Maybe angelsharks always gathered here, but until recently, no one really knew.

Along Playa de las Teresitas, rows and rows of tourists lounge on beach chairs under umbrellas or pad across soft sand to cool down in the water. The breeze creates tiny sapphire-tipped waves on the water’s surface, a magical cover for what lies beneath—an angelshark nursery.

Female angelsharks regularly migrate to these ideally sheltered waters to give birth to anywhere between eight and 25 live pups, who remain in the shallows for about a year. Feeding on cuttlefish and other small prey, they grow to around 50 centimeters, about the same length as a newborn baby. Then they disappear for years until they are mature. Where they go is a mystery.For centuries, angelsharks had been common along the Atlantic coast of North Africa and Europe, as well as the Mediterranean. The ancient Greeks fished them; Pliny the Elder described the use of their skin to polish wood and ivory. On the British Isles, they were called monkfish for their resemblance to a monk’s hooded robes. With the advent of industrial bottom trawling in the late 1800s, they were easily caught and became a common food fish. By the 1960s, aggressive fishing of angelsharks, coupled with their extremely low reproductive rate, led to a dramatic decline in their populations. Targeting them eventually became commercially unviable and the name monkfish was relegated to another species, the anglerfish.

But angelsharks were still by-catch in other fisheries, and by the early 1970s, as developers barged Saharan sand to Tenerife, the fish were pushed close to extinction in most parts of the North Atlantic and the Mediterranean.

In the European Union and the United Kingdom, it has become illegal to fish or retain angelsharks. If one is accidentally caught, fishers must return it alive to the sea. But the main threat to angelsharks remains the powerful bottom-trawling industry, which accounts for over 30 percent of fish landed in the European Union.

The story in the Canary Islands is slightly different. Michael Sealey, a marine biologist with the Angel Shark Project (ASP) in Tenerife, says that bottom trawling has never been as viable in the Canaries as in most of Europe and the Mediterranean. The seabed is mostly too deep, he explains, the underwater topography laced with jagged seamounts and reefs where fishing gear can get hung up. On top of that, the European Commission has halted all trawling in the Canaries since 2005.

But biologists only became aware about a decade ago that the Canaries host an angelshark population. Subsequently, in 2014, the Universidad de Las Palmas de Gran Canaria, Museum Koenig Bonn, and Zoological Society of London collaborated to establish ASP. The project’s goal: to gather data on critical habitats, movement patterns, and reproductive biology of angelsharks, and work with local communities and officials to protect the fish. Life history information is crucial for developing effective conservation strategies and protecting valuable, if improbable, habitat—like Playa de las Teresitas.

But angelsharks are not the easiest of research subjects. They are masters of disguise, so spotting them is a challenge. They have a peculiar flattened shape and spend most of their time lying on the ocean bottom partially covered by sand. Their coloring—reddish- or greenish-brown scattered with small white spots—helps them blend into the seabed.

Gathering data on such elusive animals, with low population densities spread over a huge area, is labor intensive. Help has come in the form of citizen science: everywhere in the Canary Islands, recreational divers and fishers are invited to make online reports of any sightings or accidental catches of angelsharks. Through an ASP initiative, dive operators conduct friendly competitions to see which company can record the most sightings, thereby increasing data collection, particularly from citizen scientists.

Rubén Martinez, a dive instructor in Lanzarote, the easternmost island of the Canaries, is a keen advocate of angelsharks and regularly volunteers for ASP surveys. He helps with procedures such as tagging the fish with either spaghetti tags—an easily attached plastic loop—or acoustic tags. Both are done on the spot without having to catch the fish or lift it out of the water. “We work in a team and practice beforehand,” Martinez says. After an angelshark has been spotted in the sand, the team places a mesh attached to a sturdy frame over the animal. They take a small sample of fin for DNA analysis and attach a tag to the base of the dorsal fin. The whole procedure, when done properly, takes less than a minute.

Surveys have shown that other beaches in the Canary Islands are also potential nursery sites. Interestingly, most of them have been altered, like Teresitas, to make them more attractive to people. On Lanzarote, Playa Chica boasts another long sweep of imported sand. It’s a magnet for divers—as well as a spectacular and easily accessible site—so the number of sightings of mature angelsharks off this shoreline is one of highest in the whole archipelago. How do the sharks react to these shoals of wetsuited humans? Alba Esteban Pacheco, a biologist and former dive instructor with Euro Divers Lanzarote, admits that while there have been instances of divers getting too close to the sharks, most dive companies are sensitive in this regard and brief their clients well. They have little choice: in 2019, Spain introduced legislation in the Canaries that made disturbing the sharks or harming their habitat and breeding grounds a criminal act subject to large fines.

Pacheco is very clear that she keeps her dive clients at least the recommended one meter distance from any angelsharks they find hiding in the sand. “Also,” she says, “these days, with everyone videoing everything and posting it on social media, it’s hard for divers to step out of line.”

But is this enough? Eva Meyers, a cofounder of ASP, acknowledges that the diving community plays a crucial role in conservation of the species. But she adds that much more needs to be done to ensure the long-term survival of angelsharks in areas like Playa Chica.

A recovery plan ASP developed with local authorities is in the final stages. It will include measures such as signage along sensitive coastlines and establishing a code of conduct for divers throughout the Canaries.

Among international dive communities, the word is out about the chance to see mature angelsharks in the Canaries, and this is a growing part of the tourism sector. Indeed, shark diving all over the world is a boon to economies. It generates over US $24-million yearly in the Canaries. Globally, shark-diving tourism generates over $300-million yearly, and local communities benefit much more from shark diving than from shark fishing. In some cases, this has led to the creation of marine reserves, such as in Fiji, which help other marine species as well.

Many divers may now be cognizant of the fragility of the angelshark population, but what about all those people splashing about and swimming in the all-important nursery areas just off the beaches? Sealey thinks that human activity in the shallow nursery areas influences angelshark behavior. On busy beaches like Teresitas, juveniles normally retreat to deeper water during the day when lots of people are around. During the COVID-19 pandemic, restrictions kept people off the beach. After almost two years of peace, angelsharks seemed unprepared for the people wading back into the water, as swimmers reported an unusual number of bites soon after restrictions lifted. The fish rely on their camouflage for protection, but when stepped on, they might lunge up from their hiding place and bite, though they usually swim away. Known locally as “gummings,” the bites are not serious and rarely draw blood. But the increase in gummings was an indication that the juveniles had adapted to remaining hidden in the shallows 24/7 to conserve energy. Post-pandemic, angelsharks have adapted again, by heading into deeper water earlier in the day and avoiding interactions with humans, as do many other urban wildlife species.

Back in the 1970s, did angelsharks also adapt to the Canaries’ headlong efforts to redesign itself for tourists? It’s intriguing to think that the massive, environmentally disruptive projects to remake beaches could have accidentally enhanced the habitat for one of the world’s rare fish species. But what’s clear is that after the breakwater was built and the sand arrived, people followed, and in the calm, shallow waters they began to see baby angelsharks. And unlike how many an association between humans and wildlife ends—in conflict and dead animals—this time it led to conservation.

After decades of the US government generally avoiding discussion of UFOs, NASA and the Department of Defense have embarked on investigations into mysterious, unexplained sightings, aerial or otherwise: what are now being dubbed unidentified anomalous phenomena, or UAPs. NASA launched a nine-month UAP investigation in October. In the spirit of the space agency’s goal of transparency for that work, on Wednesday it live-streamed a public meeting of its independent UAP study team. The panel concluded it needed quality data, noting the fragmentary nature of what was available to analyze has restricted research into UAPs.  

The subject of UAPs “has captured the attention of the public, the scientific community, and the government alike,” said Daniel Evans, assistant deputy associate administrator for research at NASA’s Science Mission Directorate, at the meeting’s outset. “It’s now our collective responsibility to investigate these occurrences with a rigorous scientific scrutiny that they deserve.” 

The 16-person study group includes planetary scientist David Grinspoon, former NASA astronaut Scott Kelly, and science journalist Nadia Drake. It’s chaired by David Spergel, an astrophysicist and president of the nonprofit science organization the Simons Foundation.

[Related: Is the truth out there? Decoding the Pentagon’s latest UFO report.]

The NASA team will write a final report by sometime in July. The study team’s mission is not to render a verdict on the nature of UAPs, Spergel said, but to set the stage for later research. They aim to clarify how NASA can go about scientifically investigating UAPs. To that end, in Wednesday’s meeting, they discussed the current knowledge about UAPs (these are not extraterrestrial), standards of evidence for determining just what they might be, and the difficulty of obtaining high-quality human reports. 

“Our role here is not to resolve the nature of these events, but rather to give NASA guidance to provide a roadmap of how it can contribute to this area,” Spergel said. 

The team has sifted through available UAP data and found that many reports can be pinned down to known sources, such as distant aircraft, sensor artifacts, high altitude balloons, or atmospheric events. When it comes to learning more about the persistently unidentifiable phenomena on record, though, the team found the information lacking. 

“The current data collection efforts regarding UAPs are unsystematic and fragmented across various agencies, often using instruments uncalibrated for scientific data collection,” Spergel said. “Existing data and eyewitness reports alone are insufficient to provide conclusive evidence about the nature and origin of every UAP event.”

[Related: The truth about Area 51 UFO sightings, according to a local expert]

It’s possible that more direct, targeted observations of UAPs could help, using everything from FAA radar installations to sensors on commercial aircraft to government spy installations. But as Sean Kirkpatrick, the director of the Department of Defense’s All-domain Anomaly Resolution Office (AARO) told the team, “Most people, including the government, don’t like it when I point our entire collection apparatus to your backyard.”

“We’ve got to figure out how to do this only in the areas that I can get high confidence there’s going to be something there,” Kirkpatrick continued, “and high confidence I’m not going to break any laws.”

While AARO may deal with some classified UAP data, the NASA team is only working with unclassified information so that its report can be made fully public. But that doesn’t necessarily mean that the data NASA has to work with is inferior to the Department of Defense’s information—many times, the classification of a UAP sighting has nothing to do with UAPs, according to Nicola Fox, associate administrator of NASA’s Science Mission Directorate, and everything to do with what snapped the photo.

“Unidentified anomalous phenomena sightings themselves are not classified. It’s often the sensor platform that is classified,” she said, to prevent foreign adversaries from understanding those sensor’s capabilities. “If a fighter jet took a picture of the Statue of Liberty then that image will be classified, not because of the subject in the picture, but because of the sensors on the plane.”

There are drawbacks for the NASA investigators working in public, however. Although he did not specify exactly what happened, Evans noted that members of study team “have been subjected to online abuse due to their decision to participate on this panel,” adding that “any form of harassment towards our panelists only serves to detract from the scientific process, which requires an environment of respect and openness.”

Harassment of NASA study team members also highlights another problem with seriously studying UAPs, according to Spergel: the stigma associated with reporting a UAP sighting, especially among some professionals. ”Despite NASA’s extensive efforts to reduce the stigma, the origin of the UAPs remain unclear, and we feel many events remain unreported,” he said. “Commercial pilots, for example, are very reluctant to report anomalies, and one of our goals in having NASA play a role is to remove stigma and get high quality data.”

One of the world’s busiest airports will soon showcase an innovative, undeniably cute way to speed up travelers’ entrances and exits. First announced earlier this month, Dallas Fort Worth International Airport (DFW) is partnering with EV Safe Charge to demonstrate how the company’s mobile electric vehicle charging station, ZiGGY, could be deployed in public spaces to economically and conveniently power up consumers’ parked cars.

[Related: Electric cars are better for the environment, no matter the power source.]

Electric vehicles are an integral component of the societal shift towards clean, renewable energy. Unfortunately, battery shortages stemming from supply chain issues alongside a need for evermore charging stations is hampering a wider adoption of green transportation. ZiGGY obviously isn’t a catch-all fix, but it’s still a novel tool that both its makers and DFW hope to highlight over the summer as part of the airport’s series of EV charging solution demos.

“We know that electric vehicles will be a big part of the future of transportation,” Paul Puopolo, DFW’s Executive VP of Innovation, said in a statement, adding their air hub is “leaning into emerging technology now so that we are prepared to meet the needs of the airport community well into the future.”

ZiGGY itself resembles a large vending machine on wheels, which makes a certain amount of sense given it dispenses electric fuel on demand. Using geofencing technology, app-based controls, and on-board cameras, ZiGGY can be deployed directly to the location of your parked EV, where a user can then connect the charging bot to their ride. To court additional revenue streams, each ZiGGY also features large video screens capable of displaying advertisements. Don’t worry about getting stuck behind it if someone is using a ZiGGY, either—its dimensions and mobility ensures each station can park itself behind an EV without the need for additional space.

Speaking with Ars Technica on Tuesday, EV Safe Charge’s founder and CEO Caradoc Ehrenhalt explained that the idea is to deploy ZiGGY fleets to commercial hubs around the world, such as additional airports, hotels, and shopping centers. “What we’re hearing from people… is the common thread of the infrastructure being very challenging or not possible to put in or not cost effective or takes too much time. And so there really is the need for a mobile charging solution,” said Ehrenhalt.

[Related: Why you barely see electric vehicles at car dealerships.]

Of course, such an autonomous vehicle could find itself prone to defacement and vandalism, but Ehrenhalt apparently opts to look on the sunnier side of things. “Ziggy is fairly heavy because of the battery,” they cautioned to Ars Technica. “It has cameras all around and sensors, including GPS, and so there potentially could be [vandalism], but I’m always hoping for the best of humanity.”

When a friend asks you to share your WiFi password, how long is your explanation? Saying “Oh, it’s a mess of letters and numbers taped to the router behind the refrigerator in the rental unit upstairs” doesn’t make things easy for them. 

There are better ways to share your WiFi. And sure, each of these tips requires some minimal hoop-jumping, but it’s a heck of a lot easier than trying to dictate a password like “dD^#i16HJ9vD” to someone while they fumble with the password field.

It’s also worth noting that if you often find yourself needing to share your WiFi password, you should set up a guest network to allow people to access your internet while keeping other devices in your home safe. We’ll explain how below, but for now let’s satisfy your immediate needs.

How to share your WiFi password on Android

Google’s operating system allows you to share WiFi passwords via scannable QR codes, so you won’t have to watch your friends hunt and peck on their phone keyboards. 

1. Unlock your phone and open the Quick Settings menu—swipe down with two fingers from the top of the screen.
2. Long-press Internet to open the menu, and then tap the cog icon next to the WiFi network you’re connected to.
3. Tap Share.
4. Your phone will ask you to verify your identity with a biometric or a passcode. Once you provide it, it’ll generate a QR code with your home network’s info.

How to share your WiFi password on iOS, MacOS, and iPadOS

Sharing a WiFi password between Apple devices is even easier—at least if you’ve done some work beforehand. Specifically, both people need to have the email address associated with their Apple ID saved in the other person’s contacts, and you need to be signed into iCloud. For WiFi sharing to work, both devices also need to have WiFi and Bluetooth on, and personal hotspot off.

Unlock the device sharing the password. Have your friend tap the network on their device. A prompt should appear on the one that’s already connected—tap Share Password, then Done.

You’ll need to be somewhat near their device, and in my experience, the process can be a little finicky, but it’s something to consider. If the prompt doesn’t come up, you can always create a dedicated WiFi QR code.

If all else fails, generate your own network QR code

If you find the options above are not working or you have a lot of people coming over and don’t want to share your password with each one, you can print (or cross-stitch, if you’re ambitious) a QR code they can scan. There are plenty of tools out there that will help with this task, but I like QiFi.org. It’s incredibly straightforward: 

[Related: Device won’t connect to WiFi? Here’s what to do first.]

1. Head to your router’s administrator page by typing 192.168.1.1 into your address bar. This is a private IP address some internet service providers use as a gateway to access their routers’ settings. If that one doesn’t work for you, there are other numbers you can try. You can also check the sticker on the bottom of your router or find its user manual. 

2. Look for an option in the settings called Guest Network and set it up with a WPA2 password, if you can.

Those of us in the Northern Hemisphere are enjoying the longest daylight hours of the year ahead of the summer solstice, and across the world many may even be able to see a unique sunspot on the surface of our favorite star.  Summer stargazing season is quickly approaching, but summer skies can be hazy which makes  some celestial events difficult to see. But there is still plenty to see in the mild night skies this June. Here are some events to look out for and if you happen to get any stellar sky photos, tag us and include #PopSkyGazers.

[Related: The Strawberry Moon, explained.]

June 1 and 2- Mars passes through Beehive star cluster

To kick off the month, Mars will be passing through a star cluster called the Beehive cluster or M44. It’s located in the crabby constellation Cancer, and Mars will appear as a brilliant red ruby surrounded by sparkly diamonds.  

To find Mars, first look for the bright planet Venus in the western sky. The two bright stars that are strung out to one side of Venus are the constellation Gemini’s twin stars Castor and Pollux. Mars should be the reddish light just above Venus, Pollux, and Castor. Binoculars and a dark sky will help you see a smattering of stars just beside Mars. 

The Beehive cluster is about 557 light-years away from Earth and is home to at least two planets. 

June 3 and 4- Full Strawberry Moon

June’s full moon will reach peak illumination at 11:43 PM EDT on June 3. Just after sunset, look in the southeastern sky to watch the moon rise above the horizon. June’s full moon is typically the last full moon of the spring or the first of the summer. 

The name Strawberry Moon is not a description of its color, but instead a reference to the ripening of “June-bearing” strawberries that are ready to be gathered and gobbled. For thousands of years, the  Algonquian, Ojibwe, Dakota, and Lakota peoples used this term to describe a time of great abundance. Some tribal nations in the northeastern US, including the Wampanoag nation, celebrate Strawberry Thanksgiving to show appreciation for the spring and summer’s first fruits. 

Other names for June’s full moon include the Gardening Moon or Gitige-giizis in Anishinaabemowin (Ojibwe), the Moon of Birthing or Ignivik in Inupiat, and the River Moon or Iswa Nuti in the Catawba Language of the Catawba Indian Nation in South Carolina.

June 21- Summer Solstice

Summer officially begins in the Northern Hemisphere at 10:58 AM EDT on June 21 which marks the summer solstice. This is when the sun travels along its northernmost path in the sky. At the solstice, Earth’s North Pole is at its maximum tilt of roughly 23.5 degrees towards the sun. It is also the longest day of the year, and you can expect roughly 16 hours of daylight on June 21 in some spots in the Northeast.

After June 21, the sun appears to reverse course and head back in the opposite direction, towards the south, until the next solstice in December. 

June 27- Bootid Meteor Shower Maximum

June’s Bootid meteor shower begins on June 22, but it is expected to reach its peak rate of meteors around 7 PM EDT on June 27. The Bootid meteors should be visible when the constellation Bootes is just above the horizon. The moon will be in its first quarter phase at the shower’s peak, and will set at about 1:30 in the morning, making for minimal light interference later in the night. 

June’s Bootid meteor shower was created by the comet 7P/Pons-Winnecke and expected to last until July 2.

The same skygazing rules that apply to pretty much all space-watching activities are key this month: Go to a dark spot away from the lights of a city or town and let the eyes adjust to the darkness for about a half an hour. Then, just sit back and let the summer skies dazzle.

For more than a decade, the king of the skyscrapers—the tallest building in the world—has been the Burj Khalifa in Dubai. With a total height of 2,722 feet, it’s the undisputed champion of the vertical world, a megatall building constructed with a core of reinforced concrete that sits on a piled raft foundation. 

Since its completion, the 163-story building has become a shining part of the world’s architectural and cultural landscape, providing a soaring platform for content that will make your stomach clench. A woman donned flight attendant garb and stood at its dizzying pinnacle not once but twice to hawk for Emirates airlines, with the second stunt involving an enormous A380 aircraft flying behind her. And Tom Cruise famously scaled its glass exterior in a Mission Impossible film.

The Burj Khalifa has owned the superlative designation of tallest building in the world since 2010, towering over everything else. “That’s pretty good staying power considering that there was actually a pretty high rate of replacement—between the replacement of the Sears Tower by Kuala Lumpur’s Petronas Towers, then Taipei 101, and then we moved onto the Burj, which is considerably higher than its predecessors by a good margin,” says Daniel Safarik, the director for research and thought leadership at Council on Tall Buildings and Urban Habitat (CTBUH) in Chicago.

“That begs the inevitable question then: What’s going to be the next new tallest building in the world? And I think the answer is, we don’t know,” he adds. “Initially it was projected to be the Jeddah Tower in Saudi Arabia, but that building has stopped construction with no specified resumption date.” 

The tallest building in the world rises into the unknown 

Adrian Smith is the architect behind the Burj Khalifa, as well as for the on-pause Jeddah Tower. In a video chat from Chicago, he reflects on the question of when and if another building will surpass the height of the Burj. “I think inevitably, that’s the case,” he says.

“One of the interesting things about the ‘tallest building in the world’ as a title, is that if one is serious about doing the tallest building in the world, there’s an enormous amount of publicity that goes along with that,” he adds. Smith is now at Adrian Smith + Gordon Gill Architecture and formerly was at Skidmore, Owings & Merrill, which is known as SOM. “We’ve had clients hire us to do world’s tallest buildings before—they get an enormous amount of publicity and then for whatever reason, it doesn’t happen. Usually, 90 percent of the time, that reason is money.” 

As for the on-pause Jeddah Tower, which used to be called Kingdom Tower, Smith says that “it’s pursuing the process of starting up again,” and adds, “I have nothing that I can really disclose at all.”

Earlier this year, the Los Angeles Times took a close look at the Jeddah Tower’s frozen progress, and other mega projects in Saudi Arabia, reporting that the tower, at 826 feet tall, “remains a construction site with no construction.” 

[Related: 6 architectural facts about history’s tallest buildings]

But regardless of the Jeddah Tower’s question mark, the Burj remains a decisive and enormous exclamation point. Each time a new tallest building in the world rises up, its designers, engineers, and contractors are pushing into unexplored territory. “First of all, the structure is the most important single thing in a supertall building,” Smith reflects. “And the reason it’s the most important thing is that very few of them are done, and the history of the design process for a supertall—especially a world’s tallest—if it’s truly a world’s tallest, it’s never been done, you don’t know what you’re going to run into.”

The world’s tallest tower came from ‘a tube’

The Burj Khalifa’s core, which is supported by buttresses, is made of reinforced concrete. That’s a change from some of the classic skyscrapers of the previous century that may come to mind. “The structure of Sears Tower is all steel,” Smith says. So too is the structure of the Empire State Building, now just the 51st tallest building in the world but standing proudly since 1931. 

“The structure of Burj Khalifa is all concrete,” he adds. “And the structure for Kingdom Tower will be all concrete as well—but when I say all concrete, they’re heavily reinforced concrete structures. A lot of steel goes into that concrete.” 

Indeed, concrete technology has evolved over the decades, allowing it to have higher and higher compressive strength—the strength it can withstand as gravity pulls on it downwards. 

Stefan Al, an architect, author of the book Supertall, and an assistant professor at Virginia Tech, charts just how much concrete has improved. In the 1950s, he says, concrete was rated at around 20 megapascals. The concrete in the Burj was 80 megapascals, and today’s can do about 250 megapascals. “So basically it’s gotten 10 times stronger—or 10 times more able to withstand compression, meaning you can have 10 times more weight coming from top,” he says. “That’s certainly super impressive.” 

There’s another benefit to concrete (don’t get it confused with cement), which is the way it gets up to where workers need it—by being pumped up and then flowing out of a tube. Reinforced concrete’s current popularity is “a function of concrete’s ability to pump, because that makes it much easier to work with,” Al says. 

That’s different from working with steel way up high, because for that, Al says, “you need super-large cranes” to hoist the beams upwards. And concrete is quick. Al notes that using concrete in a city like New York can result in a building story going up every two to three days. 

Of course, pumping concrete up against gravity produces its own challenges—and opportunities to celebrate. A company that makes concrete pumps, Putzmeister, boasted that its equipment was able to get the material up 1,988 feet—a record at the time. In 2019, they looked back on that 2008 accomplishment, punning that in helping build the Burj, “Putzmeister was a concrete part.”

Smith points out that the plans for the Jeddah Tower call for it to be made out of concrete as well, including even its top spire, which on the Burj is made from steel. “Every few years, technology advances and changes—the concrete gets stronger. There are new additives, new ways of making concrete that’s better for this kind of application,” he says. “If you think about Burj Khalifa and Kingdom [Jeddah] Tower, they’re ultimately built out of a tube that’s maybe 8 inches to a foot in diameter.” He chuckled. 

The second-tallest building in the world

Words like supertall and megatall may sound vague, but in fact they have specific definitions. A supertall building is at least 984 feet tall, while a megatall stands at least 1,968 feet high. At 1,776 feet tall, One World Trade in New York City is a supertall building, but not a megatall one, and is the sixth-tallest building globally. And a new second-tallest building in the world is set to be finished this year—it’s the angular Merdeka 118 in Kuala Lumpur, Malaysia, and measures a megatall 2,233 feet tall at the tippy top. (The current second tallest building in the world is the 2,073-foot Shanghai Tower.)

But architecture is about more than height, and Stefan Al highlights an exciting diversity of design he sees in new modern buildings. “You can really speak of a new generation of skyscrapers, which are much taller, but also, you could say, more exuberant” compared to what came before, he observes. “Most of the 20th century, we only had a handful of supertall buildings, including the Chrysler Building and the Empire State Building, but now we have more than 100, and most of them have been built in the last 20 years.” 

As for buildings with wild and varied new styles, he cites the “super slender” trend in New York City, with the skinny and supertall 111 West 57th Street as a notable example. Another is the Central Park Tower, which Adrian Smith + Gordon Gill designed. 

But buildings get even more interesting. The Capital Gate Tower in Abu Dhabi may only be 540 feet tall, but it looks like it could tip over. “It deliberately leans 18 degrees,” Al points out. He says that buildings like this one “are not very logical from a structural perspective.” 

Or check out the M.C. Escher-like CCTV Headquarters in Beijing, or Mexico City’s cool Torre Reforma. 

So will a building ever exceed the height of the Burj Khalifa? Al thinks so, saying he anticipates it happening “within our lifetime.” 

Safarik, of the CTBUH in Chicago, is more cautious, noting that the future seems murky when it comes to a building rising higher than the Burj. But one thing is clear: When it comes to the tallest buildings in the word, things have changed since the CTBUH was founded the same year that the US landed on the moon.

Memorial Day is over, but you most likely have leftover burgers, snacks, and beers in the fridge from your celebrations. The Memorial Day deals also linger with $100 off a Jackery solar generator, among other savings.

Jackery Portable Power Station Explorer 300 $239.99 (Was $349.99)

Stan Horaczek

SEE IT

The Jackery Portable Power Station Explorer 300 is an excellent starter portable power station if you want to power smaller appliances before moving on to a larger, more powerful solar generator. It weights less than 10 pounds and can be charged with an outlet, car charger, and via solar power (although you’ll have to purchase solar panels separately). It can charge up to six devices, including laptops, drones, and cameras. It may not be able to power a refrigerator, but it can keep your WiFi running (important so no one gets bored in a power outage after all the board games are exhausted).

We’re also fans of Bluetti—another brand included in our best solar generators round-up—and the company’s EB3A, 268Wh portable power station (another excellent starter portable power station) is on sale for 40% off, down to $209 (from $349).

Like the meat in your fridge during a blackout, this deal will expire if you don’t act. Although it won’t smell as bad, you’ll still feel sorry that you didn’t act sooner and avoid the situation altogether.

Best garden hose reel: Giraffe Retractable Hose Reel

Giraffe Tools

SEE IT

If you’ve ever used a vacuum with a retractable cord, you know that it’s hard to go back to winding long cords up yourself. The Giraffe is the best garden hose reel because it’s self-winding and can lock at any length you need. It’s 100 feet of ½-inch hose, wall-mountable with just four screws and anchors, and it’s a sturdy unit that retracts slowly so you won’t hurt yourself.

Best pruning shears: KOTTO Four-Pack Kit with Storage Bag

KOTTO

SEE IT

When it comes to garden clippers, you’re likely going to want more than one type. For delicate work, like cutting herbs, you need something precise and narrow, whereas you’ll need something more heavy-duty with thicker branches and stems. The best pruning shears depend on your job, but versatile bypass pruning shears that make sharp, clean cuts are generally a must-have for any garden, and clippers or scissors are easier to work with when you need precision so you don’t wind up cutting things you don’t mean to cut. So the best choice is … all of the above, which you get in this convenient gardening kit.

Best wheelbarrow: Gorilla Carts Heavy-Duty Poly Yard Dump Cart

Gorilla Carts

SEE IT

The best wheelbarrow for your garden is one that can easily and efficiently haul what you need it to, and this Gorilla cart fits the bill: It has a padded handle that can be pulled by hand or converted to hook up to a tractor or ATV. The difference between a traditional wheelbarrow and a dump cart is that the latter has a simple mechanism to release the tub vertically to easily dump out whatever you’re carrying—rocks, logs, dirt, what have you. This dump cart is versatile and easy to maneuver.

Best shovel: Hooyman Short Handle Digging Shovel

Hooyman

SEE IT

A good shovel is essential when digging flower beds or planting vegetables, and the no-slip handle on this one from Hooyman makes all the difference. Both the handle and shaft grips are textured, which makes them easy to grab even when your hands are sweaty or you’re working in rain. The shovel’s carbon blade is serrated, which Hooyman says makes it easier to break up rocks, too.

Best gardening knife: Fiskars Garden Hori Knife with Sheath

Fiskars

SEE IT

Slicing a small branch or pruning vegetables? A gardening knife is the best tool for the job, and we like the Hori Knife from Fiskars because of its two-sided construction and built-in ruler. One side of this knife is a standard blade, while the other is serrated, which means it’s ready for both slicing and cutting. Its forked tip was specifically designed for cutting through the thin stems of small weeds. The knife’s hilt has raised edges, which give you a safe place to rest your index finger and thumb while cutting things, and the included sheath is perfect for storage.

Best hand rake: Fiskars Cultivator

Fiskars

SEE IT

Some digging jobs don’t require a shovel, which is where Fiskars’ Cultivator comes in clutch. The hand rake has cast-aluminum prongs, a grippy handle, and circular hole for easy storage on a pegboard. This tool is deceptively simple, but can be used for loosening or aerating soil, and removing weeds. You could also use it to dig smaller holes for vegetable or fruit planting, or to help excavate potatoes when they’re ready to be harvested.

Best pots for seedling: DSUWAZU Peat Pots for Seedlings

DSUWAZU

SEE IT

If you want to kickstart your gardening indoors before your area gets warm enough to keep plants outside, you’ll want a set of seeding pots. This 100-piece from DSUWAZU may seem excessive, but the pint-sized pots will last several years, and even come with plant labels. We like these seedling pots because they’re made of a biodegradable material, which will break down in soil over time. The pots will stay in tact before you use them, though, so picking up a big set now means you’ll be ready for several planting seasons.

Best garden hose: Aqua Joe iberJacket Non-Expanding Kink-Free Garden Hose

Aqua Joe

SEE IT

Carrying a garden hose can be cumbersome, but this one from Aqua Joe makes it a lot easier. The 50-foot hose’s outer jacket is made from marine-grade fiber that’s abrasion resistant and won’t get kinked or twisted. Additionally, the materials Aqua Joe used are free from BPA, lead, and phthalates The company says its host is roughly half the weight as a traditional one, which makes a big difference when you’re hauling it around your backyard. The thin hose can also be easily stored in a shed or garage once gardening season is over, though Aqua Joe says it can be used in temperatures as low as 0 degrees Fahrenheit.

Best rain gauge: AcuRite Magnifying Rain Gauge

AcuRite

SEE IT

Water is essential to all life, but too much can end up killing your plants, which is why AcuRite’s Magnifying Rain Gauge is a gardening essential. It can measure up to five inches of rain, and the larger numbers are easy to read from a distance. A stake at the bottom of the rain gauge will keep it in the ground during inclement weather, but its holes allow you to screw it into the side of your home if you’d prefer to keep it elevated. In either case, its acrylic coating will prevent it from getting damaged.

Best potting bench: Yaheetech Outdoor Garden Potting Bench

Yaheetech

SEE IT

If you have enough space, a potting bench will allow you to keep all of your most-used tools in one place, and give you a solid surface to pot your plants before they go outside. This one from Yaheetech has a 44.1-inch tabletop, and stands 49.2-inches tall. This is enough space for you to spread out your tools and work for hour-long stretches without getting a backache. We like this potting bench because it’s loaded with storage, including a top shelf, pull-out drawer, bottom shelf and side cabinet. The cabinet comes with a latch, so its contents can be kept secure. Our favorite touch is the three hooks on the right side for hanging handheld tools. Most of the potting bench is wood, but its tabletop is made out of metal, which is more durable and won’t stain when soil gets spilled on it.

Best gardening gloves: Pine Tree Tools Bamboo Gardening Gloves

Pine Tree

SEE IT

A pair of gardening gloves is the most fundamental item we’re recommending, and they should be worn at all times. This is to avoid minor cuts and scrapes, but more importantly exposure to poison ivy and ticks. This pair from Pine Tree Tools are available in multiple sizes, are easy to spot because of their green color, and are thin enough to give you complete control over all your fingers. They’re even touchscreen friendly in case you need to use your phone. A textured grip on the palm-side of the gloves will make handheld tools even easier to hold, while their cuff makes them easy on your wrist and simple to remove.

But if you’re an animal lover determined to feed your local park’s residents, there are several healthy alternatives. Before you go stock up on snacks, though, always make sure you’re allowed to feed the critters in question—some areas’ rules are more lenient than others.

What to feed ducks (and other waterfowl)

The best advice we can give about feeding ducks (or other types of park fowl like swans and geese) is to imitate the types of food they naturally eat in the ponds and fields they call home. This means vegetables and nutritious grains work well, while processed “human” foods do not. Even though bread is typically made from grains, the breadmaking process renders it very filling with a relatively low amount of nutrients, two factors that can lead to malnourished ducks. Instead, try to stick with snacks that haven’t been highly processed.

For vegetables, the most important consideration is making sure that the bits and pieces you offer are small enough for waterfowl to handle. Ducks and their relatives aren’t great at chewing—while their bills help break down food, they don’t have teeth, at least in the traditional sense. Cut salad greens, vegetable peels, nuts, grapes, and other produce into small pieces before you toss them to these birds.

[Related: Why do ducks have orange feet?]

A bag of frozen mixed peas, corn niblets, and carrot pieces is one of the best options for waterfowl: these veggies are nutritious, affordable, and small enough for ducks to eat whole. Grains like oats, rice, and seeds make good waterfowl chow for the same reason. Even better, many of these little morsels will float on your local pond, keeping them easily accessible to ducks. Big chunks of food that sink to the bottom aren’t as useful.

If you’re looking to get fancy, you can also drop a couple more dollars on a bag of specially formulated waterfowl food. These pellets, available online or at your local pet store, are typically fed to pet birds and farm animals. These bite-size bits may not float on water, though, so test a few handfuls near the water’s edge before you start a feeding frenzy. This designer food may be best served up on the banks.

Other tips for feeding ducks

No matter how eager they are for a human-provided snack, your local park’s resident fowl are almost certainly not going to go hungry without you. Most ducks are perfectly capable of foraging for insects, plant life, and other nutrition sources on their own. That means you don’t need to feel bad if some of them miss out on the feast. In fact, overfeeding waterfowl can cause a host of problems, from teaching them to rely on human handouts to throwing off their natural nutritional balance. When in doubt, it’s better to stop feeding the birds sooner than you’d like than it is to feed them too much.

If you suspect a particular duck, goose, or swan may be unable to feed itself after you leave, it’s time to call in professional help. Waterfowl that live in parks are susceptible to a host of dangers from the human world, ranging from vehicle strikes to lead poisoning. Feeding them may be a temporary kindness, but it’s not a sustainable solution. If you see a bird having difficulty moving around or visibly in distress, contact your local wildlife specialists right away.

How to shop for the best Father’s Day gifts

Mark your calendars: Father’s Day 2023 is Sunday, June 18. And before the big day comes, you’ll want to ensure you’ve secured a great Father’s Day present. But never fear; there’s something for everyone. You can help fuel your dad’s current interests or get him a gift that sparks a new one. Here are our picks for some of the best Father’s Day gifts:

For the outdoorsy dad: Rux Waterproof Bag

Rux

SEE IT

From hitting the waves to hitting the slopes, outdoorsy dads need something that will carry all of their (for lack of a better term) crap. Other bags and backpacks crumble when stuffed with hiking shoes, an insulated water bottle, and a few beers—not the Rux Waterproof Bag. This packable, durable bag is waterproof (as the name suggests) and built to last, and comes with a lifetime warranty if it falters before that. It’s seamless, radio frequency-welded (read: made with magnets), and has 360-degree lash points that make it attachable to almost everything. It also rocks as a grocery bag—score! 

For serious power: Austere Surge Protector

AUSTERE

SEE IT

If your pops is a Device Dad (he has a tablet, a laptop, a cellphone, a smartwatch, and a charger, and that’s just the beginning), they’ll need a surge protector that can handle all those plugs and power. Enter the Austere Surge Protector, which has fire and power spike safety—you never know! The flexible cable helps the surge protector fit nicely into tight spaces. It also has two USB-A and three USB-C ports for even more flexibility. Plus, it has a lifetime guarantee and a five-year component guarantee: If the power strip is responsible for any damage to a plugged-in device, Austere will replace it regardless of value. 

Best kitchen upgrade: Yummly Smart Meat Thermometer

Yummly

SEE IT

Regardless of whether your dad is getting into Keto or is a strict pescatarian, a meat thermometer is a must-have kitchen device. No one wants to develop a case of food nasties from an undercooked cut of meat in their own home! The Yummly Smart Meat Thermometer requires no wires, thanks to a Bluetooth connection. Dad won’t even need to stand like a hawk over the grill or oven—the thermometer, with a coordinating app for iPhone and Android, sends notifications when it’s time to flip the food, reduce the heat, when it’s done cooking, and how long to let it rest. There are even presets to completely take the guesswork out of getting the perfect medium rare doneness—no “Dirty Work” here. 

For the coffee lover: Bruvi Bundle

Bruvi

SEE IT

So your dad got a “Don’t talk to me until I’ve had my coffee” mug in Father’s Day past? Give Pops a better coffee system this year with the Bruvi Bundle. The bundle comes with a Bruvi BV-01 coffee brewer, a variety pack of biodegradable 20 B-Pods, a water filter, and a reusable Japanese Knot Bag. The optional mobile app will let Daddio brew a cup of Joe remotely, schedule brews in advance, re-order B-Pods, and access a personal consumption dashboard if they’re super specific about their morning cuppa. It can even fit a 6.5-inch travel mug—we recommend the Hydro Flask Stainless Steel Reusable Mug on that front. 

For the stressed-out dad: Onyx + Rose Feelin’ Good Gummies

Onyx + Rose

SEE IT

Does your dad need something a bit stronger than CBD? Have you recently learned they were a grass enthusiast back in the day? The Onyx + Rose Feelin’ Good Gummies use HHC, an isomer (minor chemical variant) of Delta-9 THC (the illegal stuff). This provides a similar head and body high to the federally regulated stuff, all while following federal regulations. According to the 2018 Farm Bill, THCs (tetrahydrocannabinols) in hemp are legal provided they have a THC concentration less than .3%—these gummies meet those requirements. Pass if dad is subject to random drug screening. If they’re not, we’re partial to the peach flavor.  We also love CBD prerolls from aptly named company Dad Grass.

Best for beardy dads: Bevel Beard Trimmer for Men

Bevel

SEE IT

An electric razor is a gift your dad will actually use every day, and this one from Bevel may actually help encourage him to dedicate a little more time to his morning routine. The razor offers pinpoint precision, so he can get the exact shave he wants, and a grippy handle that makes it easy to hold with wet hands. Its battery lasts up to eight hours, so he can use it for several weeks (or one if he’s very particular about his facial hair) without charging it. This is the type of gift your dad doesn’t know he needs, but will really appreciate.

For the WFH dad: Lillipad 42 Standing Desk

Jen McCaffrey

SEE IT

Home offices can easily become a mess of monitors, coffee cups, keyboards, and tangled cords. But if the dad in your life would appreciate an organized workspace that also empowers them to get out of their office chair, the Lillipad Work Station fits the bill. This electric desk is available in two versions that rise from 6 inches to either a 42- or 48-inch standing height (recommended for people 5’9” and taller). At 67 pounds and 72 pounds each, and with metal legs, these desks are more substantial than many other options on the market but are designed with wheels for portability. 

Advanced functionality doesn’t equal advanced set-up in this case: The Lillipad comes fully assembled out of the box. Dad can plug it in, unlock the safety lock, and use the buttons on the right corner of the desk to raise and lower it to the ideal height for a chair or standing. The 46-inch-wide workspace provides plenty of room for desktops and keyboards, and you can purchase either a single monitor or dual-monitor stand separately. The workstation also features three outlets, three USB ports, and one USB-C port, so dad can plug everything in and charge their devices. And when he’s done for the day, they can easily lower it back down and use the wheels to slide it away for storage. Add a Grovemade Wool Felt Desk Pad to add some soft style to their workstation.

Best for movie-loving dads: Dangbei Mars Pro 4K Projector

Dangbei

SEE IT

Movies and TV shows can look great on a TV, but nothing beats watching them on a projector, which offers a true movie theater-like experience. Dangbei’s Mars Pro 4K is among the best we’ve tested, offering exceptional visual clarity, color, and surprisingly good sound. It runs Android, which means dad can stream their favorite media without any additional accessories. That said, the Mars Pro 4K has multiple HDMI ports, making it easy to easily connect game consoles and other peripherals. It’s luxe, but Dangbei’s Mars Pro 4K will ensure they have the best home theater system on the block.

Best for dads who love vinyl: Victrola Stream Onyx Turntable

Victrola

SEE IT

Does Dad go on and on about how much he wishes he could play his Steely Dan albums while explaining that Pretzel Logic is superior to Can’t Buy A Thrill? If so, let him relive his glory days with Victrola’s Stream Onyx Turntable. The sleek-looking, belt-driven deck has RCA outputs so that it can be connected to a traditional home audio system, but its luxe allure is support for wireless audio streaming to Sonos speakers. The record player even offers the option to play music through multiple sources at the same time. Best of all, the Stream Onyx is easy to assemble and operate, as we found out firsthand, and comes with an Audio Technica AT-VM95E cartridge so he can enjoy his collection immediately.

Best for dads who love pizza: Ooni Koda 12

Ooni

SEE IT

If dad complains how pies and slices just aren’t how they used to be, Ooni’s Koda 12 will allow him to make them to his exact specifications. This portable pizza oven can get up to 950 degrees Fahrenheit and cook personal-sized pizzas in roughly 60 seconds. Ooni has a wide range of pizza ovens, but we like the Koda 12 because of its size and the fact that its fuel source is gas, which is easier to manage and more reliable than wood or pellets for first time pizzaiolos. Ooni’s oven can also be used to roast meat and vegetables on non-pizza nights. Just remember to get dad a pizza peel and Toque to complete the experience.

Best for dads with good taste: Terra Delyssa Organic Virgin Olive Oil Gift Set

SEE IT

Has your dad continued to tell food stories from his trip around the Mediterranean right out of college? If so, Terra Delyssa’s flavor-infused olive oil can help take him back to those days. The olives are all harvested from Tunisian orchards rather than mixed with ones from different regions, which can impart a different taste. We like this gift set because each oil is infused with a different strong taste—rosemary, chili pepper, lemon, and garlic—which are all good for different applications. He’ll immediately be able to taste the difference, which means you may also be signing up for even more culinary stories from his past.

Best for stylish dads: Highland Duds Weekender Short

Highland Duds

SEE IT

Add a little pop of color to your dad’s wardrobe with Highland Duds’ Weekender Shorts. The ultra-comfy summer-friendly short pants are mostly made of cotton and very comfortable to wear. Their slim pockets are surprisingly roomy, too. Highland Duds offers the shorts in khaki and grey if he’s less flashy. Help him complete an outfit with the Maverick Long Sleeve Shirt, made from the same materials.

Best for dads who want to clean up their act: Tineco Pure ONE S11

Tineco

SEE IT

If dad wants to take a more active role in household chores—or has been using the same vacuum since the mid-’90s—Tineco’s Pure One S11 is the upgrade he needs. The cordless stick vacuum can run up to 40 minutes per charge, and comes with various attachments for different scenarios. At 12 pounds, it’ll be easy for your dad to pick up and move around, and all of its controls are conveniently located within reach of his thumb. If dad enjoys his gadgets, he’ll enjoy the fact that the Pure One S11 can be connected to your home’s Wi-Fi connection, allowing him to see how much battery is left on the vacuum and the state of its filter through an iOS or Android app.

Best for gamer dads: Nintendo Switch OLED Model

SEE IT

The Nintendo Switch is the least-powerful current-generation console, but it’s still the one we recommend for Father’s Day because of its hybrid design. The Switch can be played portably, and the 7-inch OLED HD screen really makes games pop. When dad’s home, they can connect it to a TV or projector to play on a larger screen. The Switch’s extreme popularity is matched only by its deep catalog of games, which can satisfy players regardless of their preferred genre. Whether Pops is playing games as a distraction on a long work trip or taking time to clear his backlog at home, there’s no way this gift will go unappreciated.

Best for handy dads: DeWalt Atomic 20V Max Hammer Drill

Dewalt

SEE IT

A drill is the type of gift a handy person will appreciate but never expect. This battery-powered model from DeWalt has a compact design but plenty of power for any indoor or outdoor housework. At only 2.5 pounds, a home improvement-minded dad can carry it around easily, and the drill’s LED will make it easy for them to see what he’s doing in dark environments. Despite its size, the drill can rotate up to 1,650 times per minute. A good drill will last a dad a lifetime, and if they’re still making do with a screwdriver—or a drill that needs to be plugged into an outlet for power—this upgrade will make him smile.

Best for dads who need an everyday carry: Gerber Gear Armbar Slim Drive

Gerber

SEE IT

Power tools are great, but dad won’t be able to use them everywhere, which is why you should equip him with Gerber’s Armbar Slim. The pocket-friendly multi tool consists of a bottle opener, plain-edge blade, and a screwdriver. It even has a belt clip, so he can keep it securely fastened to the inside of his pants pocket like a boss. If your dad is the practical type, he’ll immediately see the utility of each of this tool’s functions, and keep it on him at all times. The screwdriver alone (with a reversible bit, we might add), will likely save him a couple of trips to the garage each month.

Best for dads with a green thumb: Gardyn 2.0

Gardyn

SEE IT

Does dear old dad wait all year for the weather to be fair enough to grow a garden? With the Gardyn 2.0, they can enjoy growing fresh herbs and vegetables all year long. The indoor garden comes with an assortment of pods containing plant seeds. A water tank on the bottom keeps the plants hydrated, while LED strips provide them with enough light to flourish regardless of the weather conditions. The lights and water pump work automatically so that the plants will be cared for on a continuous basis without any need for much intervention. Dad will have to prune dead leaves and harvest their crops after they’re fully grown, but that’s part of the fun.

Best for dads who grill: Konnected Joe

Kamado Joe

SEE IT

The Konnected Joe is the ultimate tool for grilling, an incredibly thoughtful gift for a dad who loves cooking meat and vegetables outdoors. The charcoal grill and smoker offer rich taste that a gas grill can’t replicate, with useful smart features. Its front display allows you to monitor the grill’s temperature and the temperature of up to three pieces of meat. An electric fire starter at the bottom of the grill will ignite charcoal briquettes at the push of a button, and they’ll be able to dial in the temperature between 250-700 degrees right from the grill. All of the information displayed on the Konnected Joe’s screen can also be monitored via an app (iOS and Android) on your dad’s phone, which is especially helpful if they’re smoking a large hunk of meat for several hours. The Konnected Joe manages to bring the best aspects of charcoal cooking with the conveniences of the digital world, and we guarantee they’ll be raving to friends and family about it at each cookout.

Best for dads who just want a new TV: Samsung QN77S95CAFXZA

Samsung

SEE IT

Sometimes dad just wants a new TV to watch his favorite shows and movies—spoil him rotten with Samsung’s QN77S95CAFXZA, a 77-inch OLED set. This is a no-compromise cream-of-the-crop 4K TV with built-in Dolby Atmos speakers, native 120hz refresh rate, and a custom-designed Samsung processor that continually calibrates the TV to make it run as smoothly as possible. It’ll even upscale 1080P video to look crisp on a 4K TV, so his collection of Blu Rays and older TV shows will still look good. Because the QN77S95CAFXZA is an OLED TV, it offers incredible contrast and color reproduction, so videos and games will look as realistic as possible.

One quirk about this TV is that it’s actually so thin that it can basically sit flush on the wall. The set gets connected to a separate box (called the One Connect Box), which has an assortment of HDMI ports and other inputs. There’s no performance hit for this system, but something to keep in mind if you’re setting the TV up for him. Whether he wants to play video games, stream movies, or even listen to music in the background, the QN77S95CAFXZA is the best choice.

Best for dads who crave perfect sound: KEF LS50 Wireless II

KEF

SEE IT

CDs promised perfect sound forever in the 1980s, but KEF made good on that lofty promise decades later with the LS50 Wireless II speakers. The pair of powered speakers sport a variety of connectors, including an AUX in, Ethernet port, coaxial input, optical audio input, and HDMI port. Those physical ports are complemented by Bluetooth and AirPlay 2 support for direct wireless streaming. KEF says that the LS50 Wireless IIs’ DAC can natively play 24-bit 384kHz audio files with no compression. Each speaker is driven by a 280 watt low frequency amplifier and 100 att high frequency amplifier. If those numbers don’t mean much to you, here’s the upshot: music can sound really, really good and very, very loud through these speakers. If your father loves music more than most people (family excluded, of course), these speakers will rock (or jazz, R&B, hip hop, classicial, reggae, and pop) his world.

Best for dads who love breakfast: Cuisinart WAF-F40 Double Flip Belgian Waffle Maker

Cuisinart

SEE IT

Breakfast is considered by many to be the most important meal of the day, and Cuisinart’s WAF-F40 will turn waffles from an occasional brunch food at restaurants into an at-home staple. This model can cook two-inch-thick Belgian waffles simultaneously at one of five pre-set doneness levels. If the cook gets distracted, a loud beep will get his attention, so waffles will never get overdone. Getting two waffles onto a plate at once will allow dad (and you!) to start eating more quickly.

Best robot mower: Husqvarna Automower 415X Robotic Lawn Mower

Husqvarna

SEE IT

Robotic lawnmowers seem like a perfect gift for a lazy pop. But, there are more practical reasons you might want to consider an automower as a gift this Father’s Day. Husqvarna’s surprisingly powerful little mower is great for people who have issues with mobility and can’t get out there to mow on their own. It’s also great for tricky yards as it can cut up to 40 degrees on a slope. If you’ve ever mowed on a steep hill like that, you know it’s not fun. It requires the installation of a guide wire to keep it contained within its own yard, but following setup, mowing is simple. A trio of extremely sharp blades can cut grass as short as 0.8 inches or as long as two inches if you want something more lush. Plus, an onboard object avoidance system means your dad (or grandad) won’t run over a rock and cause collateral damage.

Best for dads who tailgate: RTIC 52 Quart Ultra-Light Wheeled Hard Cooler

RTIC

SEE IT

A wheeled hard cooler will help your old man get beverages to and from the parking lot, backyard, or beach without straining his arms or back. We like this cooler from RTIC because of its large capacity, thick wheels, lite weight, and overall performance. RTIC says it can retain ice for up to six days if its latches remain closed, which means he can use it for a backyard cookout on Sunday and keep drinks cold for a concert he’s attending the following Saturday. Another benefit to getting a cooler is that it’ll likely last a lifetime, so get ready for many compliments. We like the classic look of RTIC’s white cooler, but it also offers a red, white, and blue variant if he wants to stand out.

For dads who love the beach: Sunflow Beach Bundle

Sunflow

SEE IT

Whether your dad actually likes the beach or only goes because the rest of the family insists he’ll have a good time out of the house, this bundle from Sunflow will sort him out. It includes the company’s beach chair, which has a flip-over top to keep him in the shade, and a beverage cooler on the side to help keep his thirst quenched. The chair’s angle can be adjusted, so he can find the most comfortable spot, and a dry bag on the right side will keep his belongings from getting sandy. When heading back to the car or beach house, a pair of straps will allow dad to carry this beach chair like a backpack for easy transport.

Best outdoor accessory: Solo Stove Mesa

Solo Stove

SEE IT

We’re huge fans of the full-sized Solo Stove fire pits, but this mini version fits nicely on a patio table or by the pool. Despite its tiny size, the Mesa relies on Solo Stove’s signature airflow system to create a clean fire with almost no smoke. It starts quickly and cleans up easily, so you can fire it up and make s’mores whenever you want without having to wait for a full-sized fire to die down at the end of the night. Solo even sells miniature firewood specifically meant for use in the Mesa. It’s adorable, but not too adorable. 

Work from the backyard: Netgear Orbi 960 Black Edition

NetGear

SEE IT

Give your dad a chance to brag about their router. Netgear’s Orbi 960 Mesh Wi-Fi kit can cover up to 9,000 square feet with super-fast connectivity up to 10.8Gbps. That means anyone and everyone can take meetings or stream content in the backyard, front yard, basement, or just about anywhere else he can think of. Wi-Fi 6E technology and Netgear’s quad-band design allow for an absurd number of devices to connect to your local network without bogging everything down. The Black Edition is only available directly through Netgear’s own online shop, which also gets you a free year of the Netgear Armor security tech. It’s advanced enough to do anything a dad needs and reliable enough that you won’t have to play tech support whenever you go to their house.

For the aspiring drone enthusiasts: DJI Mini 2 SE

DJI

SEE IT

Getting started with drones can be tricky. Not only are they hard to fly, but most drones require registering with the FAA before taking to the skies. The DJI Mini 2 SE is different. It weighs just 249 grams, which fits conveniently under the FAA’s 250-gram limit for registration. Despite its being lightweight and a small size, the Mini 2 SE captures 2.7K video and employs an object avoidance system to keep it away from power lines or other hazardous obstacles.

Best watch: Citizen Men’s Star Wars Eco-Drive with Stainless Steel Bracelet

Citizen

SEE IT

Your dad’s a nerd, and that’s OK. In fact, we recommend you encourage their nerdy tendencies as much as possible. This Citizen watch is a full-on Eco-Drive model, so it doesn’t require winding. It draws enough energy from light in its environment to keep on ticking. The handsome stainless steel bracelet makes it totally appropriate for work or classy events. But, your pop can always look down and think about Star Wars while they’re wearing it. Find a more versatile piece of nerd merch than that. We dare you. 

To help your dad’s short game: Callaway Golf Chrome Soft Golf Balls

Callaway

SEE IT

Golf balls make a great gift because it’s hard to splurge on something you might whack way into the woods or chunk straight into a water hazard. Callaway’s Chrome Soft golf balls are versions of the balls pros play on tour—they won’t have to be a pro to play them. These balls promise a high launch angle, low spin off the driver, and high ball speed off the club face. In case you’re not big on golf ball specifics, those are all very helpful things for improving overall scores. The Triple Track design sports three parallel lines on the ball to help Pops lineup shots just right. Dad will think of you and your great gift as they reach into their bag and grab another ball after slicing one across the highway next to the first fairway. 

Final thoughts on the best Father’s Day gifts

You don’t need to sweat over finding a cool gift for your dad this year. If you get him a Father’s Day gift that he’ll be able to use long-term—or, even better, something he can use with the whole family—it’ll be something he treasures. Consider it a success if you find fun presents that complement one of his hobbies or unique gifts that spark interest in a new pastime. And using this gift guide should help narrow down the best options for cool gifts for any and every dad.

Garmin is well known for its expansive list of rugged fitness watches, with multiple lines specifically tailored to different activity types. And now, the options for adventurers and serious endurance athletes are even more extensive with the announcement of updated Pro versions of the epix and fēnix 7 watches. 

Most of the updates to these premium next-gen. multisport watches are incremental software changes, such as more activity types and new fitness measurement tools. But there are also a few notable hardware and build upgrades, including a new size option and AMOLED display for the epix Pro and an LED flashlight in all three sizes of both the epix Pro and fēnix 7 Pro. Both watches will also benefit from trickle-down features from the new Forerunners.

Garmin epix Pro details

Garmin just debuted its epix 2 line of watches last year. Despite how new the series is, the company is rolling out some worthwhile updates to make it even better in a new Pro version. With vibrant metrics-rich watch faces and extensive sensors/navigation features in a sleek body, the epix Pro remains a great choice for boardroom-to-backcountry adventures and weekend warriors, from climbers and mountaineers to ultra-marathon trail runners. 

Garmin

SEE IT

epix Pro and build changes

The epix came in two sizes—42mm and 47mm—while the Pro version adds a 52mm option for those who really want a statement piece on their wrist. The larger size offers more than just a dramatic look, however. Garmin packed extra battery into the 52mm version, which promises up to 31 days of battery life in smartwatch mode. The 42mm and 47mm both should provide 10 and 16 days of battery life, respectively. 

Like the epix Gen. 2, the Garmin epix Pro will be available in Standard Edition, which features Corning Gorilla Glass and stainless steel case, or the Sapphire Edition, which uses a more durable Sapphire lens and titanium case. And all three sizes get an even brighter upgraded AMOLED display for a colorful, detail-packed watch face. 

All three sizes will offer an LED flashlight, which can vary in intensity and features a strobe mode. We were glad to see the flashlight included even on the smallest watch since it is a potentially game-changing feature. It can illuminate your path while trail running or hiking in the dark and help others see you, which is invaluable if exercising near a road. 

The epix Pro also gets an updated and optimized heart rate sensor. Garmin didn’t provide any information on what exactly that means, but it says these changes will provide “enhanced multisport performance tracking.”

Fitness tracking features

Garmin watches are already robust in their fitness tracking abilities, but the company is not one to just let things be. The epix Pro will offer new activities, which include team sports such as soccer, basketball, and racquet sports, as well as horseback riding and more.

Beyond new tracking modes, Garmin also created new training features. Hill Score gives you a better idea of how your training impacts your ability to run uphill. Uphill segments are automatically detected and analyzed, and that information is combined with other physiological metrics to provide a score from one to 100. It even breaks the score down into Hill Endurance and Hill Strength, which reflect short, fast efforts versus long, sustained climbs. And it offers feedback to improve your training over time. 

The second new feature—Endurance score—looks beyond your VO2 Max, giving a more personalized look at your fitness. It analyzes both short-term and long-term endurance training and takes into account all types of activity, not just running or cycling. And, like Hill Score, it provides training feedback to help you understand your score.

Additional new features

The Garmin epix Pro will provide a unique Red Shift Mode, which changes the display to shares of red. This lessens the impact on your vision when looking at your watch in the dark and reduces any sleep cycle disturbance you might get from the standard display. You can manually turn on this display mode or schedule it to automatically turn on and off based on sunset and sunrise time. And you can even select certain activities that automatically use Red Shift Mode.

Up Ahead mode will allow you to view running points of interest, such as checkpoints and aid stations, right on the map. This allows you to better understand what’s in front of you and plan accordingly on your race or activity. 

The last feature those navigating the backcountry will especially appreciate is the new weather map overlays and relief shading on topographic maps. The weather overlays can display temperature, precipitation, and cloud cover, to help you make more informed decisions on the go. And relief shading will assist in navigation. You can also opt into Outdoor Maps+ for even more map content, including satellite imagery and more detailed maps.  

Garmin epix Pro pricing & availability

The epix Pro is available for purchase as of today, starting at $899.99.

Garmin

SEE IT

Garmin fēnix 7 Pro details

Like the epix Pro, most changes to the fēnix 7 Pro are smaller software additions. The fēnix 7 Pro still comes in 42mm, 47mm, or 51mm sizes, though you no longer have the option of a version without solar charging. You can, however, choose between Standard Solar or Sapphire Solar, depending on how robust you want your watch face. 

Like many of Garmin’s new watches lately, including the Instinct 2X, the fēnix 7 Pro will feature an LED flashlight in all sizes. It offers a broad pattern, variable intensities, red safety light, and strobe mode. 

New training features

The fēnix 7 Pro also gets a new heart rate sensor. Garmin says this next-gen sensor utilizes “more spatially diverse optical sensors and sport-specific algorithms.” It should provide even better performance tracking for more activities, giving you even more accurate insight into your training. 

Like the epix Pro, the fēnix 7 Pro will also get the new Endurance Score and Hill Score for better endurance training insight. It also gets its share of new activities, including white water rafting, motocross, overlanding, and dozens more. And the watch will provide access to the weather map overlays, new relief shading, and Up Ahead mode.

Garmin fēnix 7 Pro pricing and availability

All versions of the fēnix 7 Pro are available for purchase at a starting price of $799.99.

The verdict is in on sitting all day: It’s not good for you—but a portable desk can help. Having to stay seated in one location all day wrecks your back and overall health. Getting up on your feet and gaining the ability to move around will make you healthier and create a happier, more flexible work environment. Whether working from home, in an office, or on the go, a portable desk allows you to set up shop anywhere. Every space will have demands, so here’s how to find the best portable desk for your setup.

How we chose the best portable desks

We work, and we work till we know what works. As a remote-first office, we’ve tried many portable desks around our own homes and asked coworkers and peers for recommendations. We scrolled through specs and critical perspectives and combined that research with real-world user impressions to find the best portable desks we could stand (or sit) behind.

Best portable desks: Reviews & Recommendations

When we’re stuck in one place, work—or life, for that matter—can become repetitive, hurting our productivity. Neither sitting nor standing for hours throughout the day isn’t great for your overall health, so how about having the ability to move where you work? Feel healthier and more comfortable while you work with a portable computer desk. Also, a change of scenery can help stimulate creativity beyond the health benefits.

• Material: Steel and composite
• Dimensions: 42 x 46.25 x 24 inches
• Weight: 67 pounds

Pros

• Comes fully assembled
• Provides generous workspace
• Designed with integrated power strip
• Portable

Cons

• Heavy 
• Expensive

If you’re looking for a substantial portable desk that’s will provide maximum adjustability, consider the Lillipad Work Station. This electric desk is available in two versions that rise to either 42 inches or 48 inches (recommended for people 5’9” and taller) that allow users to stand. At 67 pounds and 72 pounds each and with metal legs, these portable desk with wheels can also support a full work station.

A key feature is that the Lillipad comes fully assembled. When the UPS man delivered the box to my apartment, he struggled to get it up the steps. But once I got it out of the box, it was easy to start using the Lillipad 42. I used to wheels to move it in place, plugged it in, unlocked the safety lock, and used the buttons in the righthand corner of the desk to raise and lower it. The 46-inch wide workspace provided more than enough room for my equipment, and if you have a single monitor or two monitors, you can purchase stands for either separately from Lillipad. 

The work station also features an integrated power system with three outlets, three USB ports, and one USB-C port, so you can plug everything in and charge your devices. When I was done working, it was easy to lower the desk to its lowest height of 6 inches for storage. That said, while this work station is designed with portability in mind, it’s worth noting that at about 70 pounds, you’ll need to lift them carefully and it’s not going to be easy to just toss one into the back of your car.

What to consider when buying the best portable desk

Creating a workspace anywhere is super helpful today, where it’s not uncommon to be working from home. The problem is, we don’t all have extra space to turn a room into a properly kitted-out office. What to do? Using a portable desk, you can create a workspace anywhere and get back to what you need to do. Bedrooms, sofas, and yards are all fair game when setting up a portable desk.

For those looking for the ease of working from bed, a lap desk can easily be set up after you’ve hit snooze a few too many times and transport you into your next conference call. If you have minimal space, you may want a standing desk extension that can be put onto a countertop.

Location

It’s great to work from an extremely comfortable location like your bed. Work guilt-free by setting up a fully functioning laptop desk for your bed. Working on a bed or sofa can also ease the strain of sitting at a desk all day. You’ll be able to prop up a notebook, lay out your laptop, scatter some snacks, and do most things you would on any other kind of desk. It’s also ideal for days off—who wants to crane their neck to watch a movie or YouTube video when the laptop could just be propped up closer to eye level?

Portability

One of the biggest benefits of a portable desk is that it allows you to set up an office in various rooms. Do you need to be seated at your desk one moment and then rearrange the space to make room for a photo shoot later in the day? Look to a portable desk on wheels for those who want to switch their workspace daily. You won’t have to lift it, so it’ll be friendlier on your back and let you transfer your gear from room to room without removing it from the desk’s surface.

Storage

If you’re setting up a home office, the last thing you want to do is turn valuable home space into a room that will only be used when you’re on the clock. A foldable desk is one of the best portable desks that allows you to create a multi-functional room in seconds.

With foldable legs, you can slide your desk conveniently under a bed or sofa to maximize space. Think about your options when turning your daytime office into a game room, study, or guest room.

Your space

You’ll want to create a portable workstation within the room’s framework for the most compact spaces. A desk that clips onto an existing table can add extra functionality to a space, and easily move with you from room to room. Make sure to look for ventilation holes to allow airflow within your laptop (and keep your legs from overheating if you choose a lap desk).

Price

If the price is a factor, you can still get the best portable desk without sacrificing quality. For most jobs, you need a surface for your laptop. If that sounds like your job, a basic lap desk is a great option that will allow you to use your computer or take some notes while sitting on a seat, sofa, or bed.

Following a troubling proliferation of AI-generated and manipulated media, Twitter announced on Tuesday its plans to expand its Community Notes system to flag altered and fake images. First launched late last year shortly after Elon Musk’s $44 billion acquisition of Twitter, Community Notes built upon the company’s previous Birdwatch program aimed at leveraging unpaid, crowdsourced fact checking of tweets to rein in misinformation and hoaxes.

[Related: Why an AI image of Pope Francis in a fly jacket stirred up the internet.]

The expansion is currently in an “experimental” testing phase, and only pertains to posts containing a single image. Twitter states it plans to extend the feature to handle tweets featuring additional media uploads such as GIFs, videos, and multiple images in the near future. As of right now, however, only those signed up as a Community Notes contributor with a user rated Writing Impact score of 10 can see the option to flag a post for its accompanying media instead of just its text. According to Twitter’s Community Notes page, “Tagging notes as ‘about the image’ makes them visible on all Tweets that our system identifies as containing the same image,” meaning that other users’ tweets containing the same image alongside different text will hypothetically contain the same flag.

Twitter’s Community Notes team warned that the new feature’s accuracy could still produce both false positives and negatives for other tweets.  “It’s currently intended to err on the side of precision when matching images,” they explained, “which means it likely won’t match every image that looks like a match to you.” Twitter added that its team will continue to “tune this to expand coverage” while also cutting down on “erroneous matches.”

The new feature arrives just days after a fake image depicting an explosion at the Pentagon began circulating on Twitter, first via an account claiming association with Bloomberg News. The now-suspended account included a “Blue Checkmark” that for years reflected an account’s verified authenticity. Following Musk’s company takeover, a verification can now be obtained via subscribing to the premium Twitter Blue user tier.

[Related: Twitter’s ‘Blue Check’ drama is a verified mess.]

Twitter has relied extensively on crowdsourced moderation via the Community Notes system after axing the majority of its staff dedicated to trust and safety issues. On Wednesday, The Wall Street Journal reported the social media platform is now worth approximately one-third of the $44 billion Musk paid for it.

It’s never too late to get better handwriting. We don’t mean calligraphy level, which would make your doctor’s office check-in forms look like royal decrees from the 1500s. We mean legible and consistent, regardless of whether you use print or cursive. 

Just like most aspects of life, you can improve your handwriting with practice. Repetition will help you gradually change your style, and you’ll eventually reach a point where letters flow naturally and beautifully from pen to paper. We can’t promise the words will make sense, but at least they’ll look pretty. 

Avoid thick or spiral notebooks and instead opt for one with a flexible binding that you can open flat. This will prevent the heavier side of your book from trying to pull the whole thing closed, and eliminate any wrist discomfort a thick spiral may create as you approach the end of each line. Thinner notebooks will also keep your hand from losing support as you write the final lines on a page. 

Next, find a paper layout angle that suits your writing. Don’t fall for the notion that the only correct setup is vertical, as that can force your hand and wrist to adopt an unnatural writing position, which could lead to pain and even injury. There’s absolutely no shame in positioning your sheet of paper or notebook at a 45-degree angle or even a totally horizontal alignment. The best way to find out what angle works for you is to start with your paper laid vertically and then rotate it to the left (if you’re right-handed) or the right (if you’re left-handed) until you’re comfortable. This is why having a spacious surface to write on matters, as you won’t want to knock down any desk trinkets while you play around with your paper. 

Take as much time as you need to ensure your setup is to your liking. You’ll find this will not only help you improve your handwriting but it will also be relaxing. You’re welcome. 

The best way to know if a pen is right for you is to try it. If you can, go to a stationery store and take your time sampling the pens there—write a couple words on the provided pads and see how each pen feels. Maybe buy two or three to keep testing at home. If you have no idea where to start, you can always give some fan favorites a test drive. 

Many people swear by the Pilot G-2, for example. It comes in several formats, but the tried-and-tested version has a built-in grip, is retractable, uses quick-drying gel ink, and comes in myriad colors. If you want to go with a classic, try BIC’s Cristal or Round Stic pens. You’ve probably written with these a million times before, and they’re a staple because of how comfortable and reliable they are. Some more ideas: Uniball’s Signo, Pentel’s RSVP, Sakura’s Pigma Micron, or any gel pen at Muji. These are all inexpensive writing tools with their own fan bases, so you should be able to find something that works among them. 

If you want to try your hand at fountain pens, start with something designed for beginners that—hopefully—is compatible with disposable ink cartridges, or even comes pre-loaded with ink. This will prevent you from having to buy a bottle of ink and a refillable cartridge, unless you’d really like to. Pilot’s Kakuno or Schneider’s Ray fountain pens are solid, inexpensive choices—they’re light and comfortable, and can prepare you to move on to more serious fountain pens in the future. 

When you write, do it at a normal pace (not too fast, not too slow) and mind your hold on the pen. If your nails are white from the force you’re exerting, your grip is too strong—relax your hand and try again. This is important because an excessively strong grip will lead to pain and discomfort, which can result in hand and wrist cramping, as well as injury. On top of that, pain will also affect the consistency of your handwriting and eventually deter you from putting pen to paper at all, rendering this whole process useless. 

Once you have a comfortable grip, check it every few minutes and correct it if you need to. If you’re having trouble controlling your pen, you can always change your tool or try a pen grip—one of those small rubber tubes that slip right onto your pen or pencil for better control. 

These are the elements you’ll need to focus on to improve your handwriting. No matter if you do cursive, print, or a combination of the two, you want a style that anybody can read clearly, is mostly the same across the page, and has letters that look more or less consistent. This doesn’t mean your handwriting should be perfect or resemble words on a screen (let alone calligraphy)—your handwriting is unique to you and you should embrace it as such. 

If there are aesthetic elements you want to change, or if you want to alter the way you write altogether, draw inspiration from others. A quick web search will turn up thousands of handwriting enthusiasts sharing their own pristine note pages. Take a look at them, find what you like (loose elements or entire styles), mimic it, and make it yours. 

A helpful way to practice is by making your exercises a part of your everyday life. You can do this by taking up a hobby like journaling or meditative writing. This will give you the opportunity to sit down for a couple of minutes each day and put your growing skills to good use. 

If you’re not into journaling, you can just set aside some time to practice every day. Find books, poems, and songs you like, and transcribe them. You can also write down your own train of thought if you can keep up with it. Your writing doesn’t have to be good, or even make sense—the point is to write, and as long as you’re putting words together, you’re getting some practice. 

On top of that, take every opportunity you have to write instead of typing. Keep notepads and pens around your desk and home, and pick them up to write reminders, and lists. If time is not an issue, forgo emails and opt for writing a letter or sending a postcard instead. It’s not only extra practice, but it’s a nice, old-fashioned thing to do and people love it.

A reminder: take your time and be patient. Speed will come once your hand learns the movements you’re teaching it. The more you write, the faster and more organically your lines will come. In the meantime, focus on form and consistency. From time to time, take a moment to analyze your handwriting to see how much you’ve progressed and what you still need to improve. Don’t forget about your grip, either, and check on it often to see if you need to loosen up. 

For the more independent learners, there’s also a lot of practicing material online, like worksheets and guides, that you can download at a cost or even for free. Some of them have slanted lines that can help you keep your angles consistent, and some of them have full instructions on the best ways to join letters and use spacing. 

It bears repeating: handwriting is not calligraphy, and it’s as unique to you as your fingerprints. It doesn’t have to be perfect, and it doesn’t have to look like someone else’s, so make embracing the chaos part of your process.

Libraries are full of unique and missing oddities from long lost letters to famous forgeries. A newly discovered record of live comedy performance in medieval England is yet another example of how deep the roots of British theater run. In a study published May 30 in The Review of English Studies, researchers describe a 15th century manuscript with slapstick, lively text mocking everyone from kings and priests down to lower classes. If that’s not enough, the naughty narrative encourages drunkenness and features a killer rabbit.

[Related: Codebreakers have finally deciphered the lost letters of Mary, Queen of Scots.]

These new texts also contain the earliest recorded use of a ‘red herring’ in the English language, which is a misleading statement, question, or argument that is meant to redirect the conversation or text conversation away from its original subject. Additionally, it fills in some knowledge gaps regarding comic culture in England between Geoffrey Chaucer and the Renaissance’s William Shakespeare.

In the Middle Ages, minstrels often traveled from taverns and fairs to entertain people. Fictional minstrels such as Robin Hood’s Allan-a-Dale, are common in literature, but historical references to actual performers are more rare. When the minstrel was performing these newly found works, the Wars of the Roses were still raging. Life was very difficult for the majority of English people. However, study author James Wade, an early English literature specialist from Cambridge University, says this text shows that fun entertainment was still flourishing as social mobility increased.

Wade found the text when researching in the National Library of Scotland. Wade saw that a scribe had written: “By me, Richard Heege, because I was at that feast and did not have a drink.”

“It was an intriguing display of humor and it’s rare for medieval scribes to share that much of their character,” Wade said. This little joke encouraged him to look into why, how, and where Heege had copied these texts.

This new study focuses on the first of nine booklets that make up the larger Heege Manuscript. The booklet contains three texts that Wade concludes were copied down in 1480 from a memory-aid written by an unknown minstrel that likely performed them near the Derbyshire-Nottinghamshire border in central England. The three texts are a mock sermon written in prose, a tail-rhyme burlesque romance titled “The Hunting of the Hare,” and an alliterative nonsense verse called “The Battle of Brackonwet.” 

“Most medieval poetry, song and storytelling has been lost,” Wade said in a statement. “Manuscripts often preserve relics of high art. This is something else. It’s mad and offensive, but just as valuable. Stand-up comedy has always involved taking risks and these texts are risky! They poke fun at everyone, high and low.”

[Related: Medieval knights rode tiny horses into battle.]

All three texts are comedic and designed for live performance, since the narrator tells the audience to pay attention and even to pass him a drink. The texts also feature regional humor and inside jokes for a local audience.

Wade believes that this minstrel wrote part of his act down since the many nonsensical sequences would have been very difficult to recall solely by memory. 

“He didn’t give himself the kind of repetition or story trajectory which would have made things simpler to remember,” he said “Here we have a self-made entertainer with very little education creating really original, ironic material. To get an insight into someone like that from this period is incredibly rare and exciting.”

Like many present day comedians and actors, medieval minstrels are believed to have had day jobs as peddlers and plowmen, but performed their theatrical gigs at night. Some also may have even gone on tour by traveling the county, while others stuck to local venues. Wade believes the minstrel in these new texts was more of a local performer. 

“You can find echoes of this minstrel’s humor in shows like Mock the Week, situational comedies and slapstick,” said Wade.“The self-irony and making audiences the butt of the joke are still very characteristic of British stand-up comedy.

Over 350 AI researchers, ethicists, engineers, and company executives co-signed a 22-word, single sentence statement about artificial intelligence’s potential existential risks for humanity. Compiled by the nonprofit organization Center for AI Safety, a consortium including the “Godfather of AI,” Geoffrey Hinton, OpenAI CEO Sam Altman, and Microsoft Chief Technology Officer Kevin Scott agree that, “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”

The 22-word missive and its endorsements echo a similar, slightly lengthier joint letter released earlier this year calling for a six-month “moratorium” on research into developing AI more powerful than OpenAI’s GPT-4. Such a moratorium has yet to be implemented.

[Related: There’s a glaring issue with the AI moratorium letter.]

Speaking with The New York Times on Tuesday, Center for AI Safety’s executive director Dan Hendrycks described the open letter as a “coming out” for some industry leaders. “There’s a very common misconception, even in the AI community, that there only are a handful of doomers. But, in fact, many people privately would express concerns about these things,” added Hendrycks.

But critics remain wary of both the motivations behind such public statements, as well as their feasibility.

“Don’t be fooled: it’s self-serving hype disguised as raising the alarm,” says Dylan Baker, a research engineer at the Distributed AI Research Institute (DAIR), an organization promoting ethical AI development. Speaking with PopSci, Baker went on to argue that the current discussions regarding hypothetical existential risks distract the public and regulators from “the concrete harms of AI today.” Such harms include “amplifying algorithmic harm, profiting from exploited labor and stolen data, and fueling climate collapse with resource consumption.”

A separate response first published by DAIR following March’s open letter and re-upped on Tuesday, the group argues, “The harms from so-called AI are real and present and follow from the acts of people and corporations deploying automated systems. Regulatory efforts should focus on transparency, accountability and preventing exploitative labor practices.”

Hendrycks, however, believes that “just as it would be reckless to exclusively prioritize present harms, it would also be reckless to ignore them as well.” Hendrycks likened the moment to when atomic scientists warned the world about the technologies they created before quoting J. Robert Oppenheimer, “We knew the world would not be the same.”

[Related: OpenAI’s newest ChatGPT update can still spread conspiracy theories.]

“They are essentially saying ‘hold me back!’ media and tech theorist Douglas Rushkoff wrote in an essay published on Tuesday. He added that a combination of “hype, ill-will, marketing, and paranoia” is fueling AI coverage, and hiding the technology’s very real, demonstrable issues while companies attempt to consolidate their holds on the industry. “It’s just a form of bluffing,” he wrote, “Sorry, but I’m just not buying it.”

In a separate email to PopSci, Rushkoff summarized his thoughts, “If I had to make a quote proportionately short to their proclamation, I’d just say: They mean well. Most of them.”

Over three million years ago, a 500-plus pound marsupial roamed Australia, winning the prize of the continent’s first long-distance walking champion. In a study published May 31 in the Journal of Royal Society Open Science, a team of scientists described the discovery of this new genus using advanced 3D scans and the partial remains of a 3.5 million year old specimen. 

Most earlier studies on this group have focused on its skull since other skeletal remains are rare in Australia’s fossil record. The skeleton described in this new study, found at Kalamurina Station in southern Australia in 2017, is special since it is the first that was found with associated soft tissue structures. The authors used 3D-scanning to compare the partial skeleton with other diprotodontid material housed in collections all over the world.

The new genus Ambulator, meaning “walker” or “wanderer,” had four giant legs which would have helped it roam long distances in search of food and water compared to its earlier relatives. It belongs to the Diprotodontidae family, an extinct family of big, four-legged, herbivorous marsupials that lived in New Guinea and Australia. The largest species was Diprotodon optatum, which was about the size of a car and weighed almost 6,000 pounds. Diprotodontids were an integral part of the region’s ecosystem before going extinct about 40,000 years ago. 

“Diprotodontids are distantly related to wombats – the same distance as kangaroos are to possums – so unfortunately there is nothing quite like them today. As a result, paleontologists have had a hard time reconstructing their biology,” study author and Flinders University PhD student Jacob van Zoelen said in a statement. 

Ambulator keanei lived during the Pliocene era when Australia saw an increase in grasslands and open habitats become more dry. To have enough to eat and drink, diprotodontids likely had to travel great distances. 

“We don’t often think of walking as a special skill but when you’re big any movement can be energetically costly so efficiency is key,” said van Zoelen. “Most large herbivores today such as elephants and rhinoceroses are digitigrade, meaning they walk on the tips of their toes with their heel not touching the ground.  “

Diprotodontids are plantigrade animals, which means that their heel-bone makes contact with the ground as they walk. This is similar to the way humans walk and helps distribute the weight while walking, but does use more energy when running. According to van Zoelen, diprotodontids also have extreme plantigrady in their hands. The bone of the wrist is modified into a secondary heel and this “heeled hand” may have made early reconstructions of the animal look a little bit bizarre.

“Development of the wrist and ankle for weight-bearing meant that the digits became essentially functionless and likely did not make contact with the ground while walking.” said van Zoelen. “This may be why no finger or toe impressions are observed in the trackways of diprotodontids.”

George Washington’s palm tree. Thomas Jefferson’s sloth. Edward Harris’s hawk. Quite a few species come with a person’s name attached to them. Sometimes these names — formally known as eponyms — memorialize the original collector. Sometimes it’s a scientist’s family member, a benefactor or government leader, a colleague, or even a celebrity. According to one official estimate, eponyms make up around 20 percent of all animal names in use.

Many species got their eponyms during the early days of scientific collecting, which was partially fueled by the broader colonization programs of European powers throughout the 18th, 19th, and 20th centuries. Over the past few years, however, that history has come under increased scrutiny. In 2020, for instance, amid the protests over the murder of George Floyd by a Minneapolis police officer and the push to remove Confederate monuments, some ornithologists began questioning whether birds named for Confederates and slaveholders should be retitled.

Now, an international group of researchers argues that it’s time to move away from eponyms entirely. “In short, we believe that naming species in honour of real people is unnecessary and objectively difficult to justify,” the authors wrote in a recent paper in the journal Nature Ecology and Evolution. “The Earth’s biodiversity is part of a global heritage that should not be trivialized by association with any single human individual, whatever their perceived worth.”

The authors of the paper are wading into an ongoing and contentious debate — and the scientific institutions responsible for approving new species names aren’t budging.

The goal of naming species — or nomenclature — is to make sure scientific names are uniform across different fields and research labs, said Luis Ceríaco, a commissioner with the International Commission on Zoological Nomenclature, which controls the naming of animal species. “It’s a space to promote stability and promote universality on the use of names,” Ceríaco added. “What we want is to have a set of rules that allow people to really know what they are talking about when referring to species.”

For this reason, the ICZN and its partner organization, The International Association of Plant Taxonomy, follow established codes that prioritize older names, and only alter them for reasons of science and stability.

Proposals to rename species due to social or political concerns have attracted both criticism and support. In February 2023, a group of ICZN commissioners — including Ceríaco — put out a paper against renaming species on ethical grounds. Deciding which eponyms should be replaced due to “perceived offensiveness” isn’t in the code’s remit, they wrote. “Owing to the inherently subjective nature of making such assessments, it would be inappropriate for the Commission to assert judgments on such matters of morality, because there are no specific parameters to determine thresholds for offensiveness of a scientific name to a given community or individual, either in the present day or in the future.”

Other scientists, however, have been happy to step into the gap.

The push to reassess problematic species names isn’t new. Consider the case of Anophthalmus hitleri, a cave beetle named after Adolf Hitler in the 1930s, the eponym of which — in addition to honoring a historical genocidaire — has made the insect a target for some collectors. Yet despite calls to drop the eponym, the species has not been renamed by the ICZN. “The logic to date in preserving ‘hitleri’ is that the name per se is not offensive,” entomologist May Berenbaum noted in a 2010 issue of American Entomologist. “Frankly, though, a scientific name that sentences a species to extinction at the hands of fanatical Fascist memorabilia collectors causes considerable offense, at least to me.”

More recently, in 2015, the Rhodes Must Fall movement — a reference to Cecil Rhodes, the former prime minister of British colonial South Africa — launched discussions in the botanical sciences about replacing “culturally offensive and inappropriate names,” which grew alongside similar debates in ornithology around the 2020 Black Lives Matter protests.

For some people, the stakes of such decisions can feel high. “Naming and language have power. The way that you use language tells people whether they belong or not,” Earyn McGee, a conservation biologist and organizer of Black Birders Week, told Undark in 2020. The refusal to change species names, she said, “tells Black people and other people of color that they don’t matter, that they’re not important.”

Such movements have, in turn, led some taxonomists to argue that renaming species injects political considerations into taxonomy, opening up thorny questions. After all, where should scientists draw lines between good actors and bad ones? (Should species named after Queen Victoria be replaced? What about plant names commemorating American slaveholders George Washington and Thomas Jefferson?)

“We have a code of ethics,” Ceríaco said, “and the ethics part says that no one should erect a new name knowingly that’s going to cause offense.” However, he added, the ICZN emphasizes the freedom of authors to name species as they see fit, so they also don’t revise names that break their ethics code. “It’s always on the responsibility of the author. We strongly suggest for people to be sure that what they’re going to erect is not going to cause offense to anyone.”

The alternative, Ceríaco said, would be for the ICZN to have to adjudicate which names are acceptable, opening “a pandora’s box.” Allowing such revisions at all would affect the work of global researchers, conservationists, and others who depend on a stable taxonomic framework. “We’re not being dismissive toward the arguments that the names are offensive,” he said. But, he added, the consequences of changing the names would be trickier than keeping them.

Not all researchers were convinced by the ICZN’s argument. Some of them, like Patrícia Guedes — a biologist with the CIBIO Research Center in Biodiversity and Genetic Resources — banded together to in March 2023, pointing out that eponyms were effectively more trouble than they were worth. Part of the issue with eponyms, they noted, was that the practice is inextricably bound up with science’s colonial history: Many past researchers came from colonizing European nations, and as a result many species ended up named after White, male, upper-class Europeans. In Africa alone, the researchers found, 1,565 species of birds, reptiles, amphibians, and mammals — a quarter of the continent’s native vertebrates — are eponyms, the majority of which honored “colonizers or people of colonial descent.”

“A name that is considered innocuous by some may be perceived as offensive by others, and names that were once considered inoffensive are not necessarily viewed in the same way in a post-colonial world,” the authors wrote. Overturning all prior eponyms would be ethically sound but practically unfeasible, they conceded. Still, the authors argued that the ICZN could put taxonomists of the species’ native region in charge of renaming proposals.

Guedes told Undark that it would be neater — and easier — to tighten the ICZN code’s rules to restrict eponyms going forward. As long as organisms are named after people, she said, such arguments about which names are appropriate will continue: “I’m sure there are other ways of honoring people who’ve contributed to science that’s not attaching their name to another living being.”

Guedes and her colleagues face an uphill battle: Many taxonomists like eponyms. “I think it’s positive in many, many cases,” Ceríaco said. He himself has described around 40 species, some of them eponyms, including a species of viper named after James Hetfield from Metallica. (This is a bit of tradition in taxonomy: Consider Taylor Swift’s millipede, or Leonardo DiCaprio’s snake.) Such names are a chance to get communities that generally don’t pay attention to such discoveries involved, he said. Eponyms also give researchers the chance to name species after scientists from the countries in which they were found, he added, such as an Angolan gecko that honors local scientist Francisco M. P. Gonçalves.

“There are certainly unfortunate eponyms out there,” Stephen Heard, an ecologist and author of “Charles Darwin’s Barnacle and David Bowie’s Spider,” a book about eponyms, wrote to Undark in a Twitter message. “There are also wonderful ones that bring attention to underrecognized figures in science, including Indigenous people, women, and more.”

It’s an honor for a researcher to have a species named after them, said Brian Sidlauskas, an ichthyologist at Oregon State University. (He would know: There’s an Amazonian fish with his name on it.) But while he’s not interested in barring their use, he does think the ICZN could create a process for ditching problematic names — perhaps through a panel of experts tasked with weighing in on proposed name changes. “There really are some names in history that genuinely are really offensive, so having some mechanism for changing those is a good idea,” he said — a position other researchers have staked out as well.

In addition, the ICZN’s stance against making changes for ethical reasons is a “classic slippery slope argument,” Sidlauskas said. “It’s clear that they don’t want to the responsibility for doing so. But if not them, then who has the responsibility and ability?”

Others argue that naming practices should change on a community level, regardless of what the ICZN does. “Going forward I think that White Europeans should not be naming species from countries that are not their own after other White Europeans,” said Laura Jennings, a botanist at Kew Royal Botanic Gardens. While she doesn’t feel it’s for her to tell colleagues how to name species in their own country, she’d decline her own eponym. “My preference is to name species after a characteristic of the plant, a place name, or a name in a local language,” she added. “Something that links the plant to its native habitat.”

The broader community discussion isn’t going anywhere. The ICZN is currently working on the 5th edition of its formal code, Ceríaco said, which will be delivered for comment and debate by the community before it’s ratified in the next year or two. That’s part of the reason he and his colleagues made their position clear earlier this year, he said — to foster debate.

It’s a goal that Guedes’ team shares. “I don’t think the real change is going to happen anytime soon. But what we wanted to do was create a space for discussion,” she said.

“And I think we’re achieving that,” she added.
