Alopecia areata is an autoimmune disorder caused when the immune system attacks hair follicles, mistaking them as foreign invaders. The hair loss may begin as small circular bald patches around the head, but it can expand to larger overlapping patches. Unexpected flare ups from extreme stress can worsen hair loss. The condition may affect a person’s self-image and can be a target of harassment, as when presenter Chris Rock bullied actor Jada Pinkett Smith for having alopecia at the Oscars in March....

Design and feel The X-T4 has a more robust feel than the X series cameras that have come before it. The hand grip is more substantial, the dials on the top have been slightly reorganized, and the dual memory card slots now sit side by side. The larger battery motivates most of these ergonomic changes since it demands more space inside the body.. Although it’s bigger than the X series that have come before it, it’s still compact and the design changes in the handgrip make for a very comfortable shooting experience....

New research out yesterday in Nature Food shows that food miles, or the distance between the place where food is grown to your plate, has a much higher carbon footprint than previously estimated. The carbon cost is actually around 19 percent of all food-related transportation emissions. Taking the entirety of the food supply chain into account, global food miles add up to around 3 gigatons of carbon dioxide equivalent emissions, which stands around 3....

When Jacques Cousteau penned a story for Popular Science in February 1969, NASA was months away from crossing 240,000 miles of space to land a man on the moon, but marine technology was barely capable of sustained underwater exploration. To many, Cousteau, a French naval officer during WWII, is remembered for his nearly decade-long TV series, The Undersea World of Jacques Cousteau, which broadcast into millions of homes the wonders of ocean life and exposed the devastation of human activity....

Which got us wondering: What exactly do forensic chemists do? And why might some feel compelled to cheat? In crime television shows, investigators brush evidence into tiny baggies in leaky warehouses, then send the samples off to the crime lab. Minutes later, the results magically materialize, the bad guy gets convicted, and everyone else lives happily ever after. But as Dookhan’s case suggests, the reality is much less tidy and offers a dark portrait of the perverse incentives of a key aspect of the criminal justice system....

Google says they will come to the stable releases later this year and that their next milestone for 2022 will be to release an API (an application programming interface) to allow native Android apps to support them....

While you can always opt to use a run-of-the-mill charging hub, not all of them are designed to cater to different kinds of devices. For instance, if you’re using gadgets within the Apple ecosystem, you have to use a different charger per device. But the last thing you want is to have a chaotic array of chargers on your nightstand. It’s better to streamline your charging process, and luckily, the 3-in-1 Fast Wireless USB Charging Dock Station for iPhone is on sale for a special price during our Deals Day event....

If you’ve yet to dip your toe into livestreaming, you’ll need to decide on a platform, and we’re looking at three of the biggest here: Twitch, YouTube, and Mixer. As far as the mechanics of uploading goes, you won’t find many major differences—all three are equally capable of hosting your stream and enabling other people to tune in. Your choice might come down to the machine you play on—the brand of computer, console, or phone you use could determine the best platform for you....

This issue is one that needs to be addressed—and fast, especially in the US. This March, the Biden-Harris administration has pledged to deploy 30 gigawatts of offshore wind power in the country in the next decade. A single gigawatt can power over 100 million LED lights. The first major offshore wind farm project called Vineyard Wind 1, an 800-megawatt farm anchored off the coast of Massachusetts, was officially announced this May....

As reported by Breaking Defense, the Phoenix Ghost is a drone-missile similar to the Switchblade already fielded by Ukraine. The Pentagon initially claimed the Phoenix Ghost was developed for Ukraine after Russia’s February 24 invasion, but Pentagon Press Secretary Jack Kirby clarified the development timeline, saying instead that the Phoenix Ghost was created before the invasion, and was “developed for a set of requirements that very closely match what the Ukrainians need right now in Donbas,” as Breaking Defense reported....

After being fortunate enough to return home—his house was fine—he began seeking ways to become more educated about both fires and emergency response. He took wildland firefighting courses, went on ride-alongs, and toured a 9-1-1 call center; throughout it all, he kept returning to the idea of wanting better communication during critical moments. So, he decided to use his background as a software engineer to create an app that would address the issue....

If you want a clip from a video-sharing site like YouTube or break.com, one super-cinchy way is to plug the URL into KeepVid (keepvid.com). It not only downloads the clip for you but can also convert it into an MP4 file that will run on most video players. Several helper apps can do the job as well. If you’re on Firefox, use the Tools menu to install the DownloadHelper add-on, which places a convenient video-capture button right on your browser....

In a paper published this week, researchers at Meta AI revealed a text-to-video generator they call Make-A-Video. It takes a written prompt like “a teddy bear painting a portrait” or “a dog wearing a superhero outfit with red cape flying through the sky” and returns a short video clip depicting the machine learning model’s best attempt at recreating it. The videos are clearly artificial, but very impressive all the same....

As of today, the shoes have now entered their third iteration. Nike has dubbed the new version, the Vaporfly Next%, implying that the gain in efficiency that any one runner gets isn’t stymied at four as with the previous version. Overall, the shoe has moderate tweaks to its design. Nike markets the racing kicks as a tool to help elite marathoners break the 2-hour marathon, a human potential barrier akin, in some ways, to the plight of the 4-minute mile of the 1950s....

There are many ways fish scope out a reef to return to. These underwater communities are very noisy places full of vocal marine animals and invertebrates, and given that sound travels far underwater, small fishes are able to tune in to the traffic reports to judge a reef’s quality. Environments that sound good also tend to attract more new animals. Healthy reefs have a rich soundscape. “Lots of the invertebrates and the fishes make weird and wonderful noises for all sorts of weird and wonderful reasons....
