Red light therapy devices are everywhere—from lamps, to full-body mats, to those glowing face masks flooding my social media feed. I usually see red light therapy advertised for "younger-looking skin," but I'm not interested in these devices as a means to slow down aging—I'm interested in them as a recovery-obsessed athlete with very sore muscles.These gadgets promise to boost athletic performance, speed muscle recovery, and reduce inflammation, all by bathing your body in specific wavelengths of red and near-infrared light. But do these trendy tools live up to the hype, especially for muscle recovery?What red light therapy advocates claimRed light therapy devices typically emit light in the red (620-670 nanometers) and near-infrared (800-850 nanometers) spectrum. Manufacturers claim these...

This week, OpenAI released ChatGPT Atlas, the company's first AI web browser. Atlas lets you surf the web like any other browser, but, as you might expect, comes with ChatGPT integration. You can log into your account and tap into the assistant via the sidebar menu, which will remember not only past conversations, but your browsing history as well. Like other AI browsers—namely Perplexity Comet—the browser has an "agent mode," which can take actions on your behalf. You can ask it to order you food through DoorDash or buy you plane tickets on Kayak instead of doing those things yourself.While that might sound useful to ChatGPT fans, I had trouble recommending the browser to people, considering the security vulnerabilities AI browsers are currently facing. Any browser that has agentic featur...

For the past few years, Google's Pixel phones have had recurring problems with calling 911, and the issue has once again reared its ugly head. Over the past 24 hours, multiple users on Reddit have complained about being unable to call 911, while the Bell carrier in Canada issued a warning that the Pixel 6 and up was also having problems contacting emergency services on its network.According to user Fabulous_Disaster730, who posted yesterday about difficulties contacting emergency services during a gas leak, her Pixel 9 Pro repeatedly prompted her to turn on wifi calling or turn off airplane mode before she could call 911, despite her having full signal on both 5G and wifi. The phone would then freeze and restart. After multiple attempts, she resorted to asking a friend to place the call fo...

I recently reviewed Even Realities G1 smart glasses (they're very cool) and the first real-world thing I used them for was scamming someone. I told a local bartender I had an encyclopedic knowledge of film, and I would answer the hardest movie trivia question he could come up with in exchange for a drink. After a short consultation with Google, dude came back with "Who directed 1922's Cabinet of Dr. Caligari?"I tilted my head thoughtfully and repeated the question as if verifying I heard him right. The AI agent silently did its thing, and in about three seconds, the answer was floating before my eyes, totally invisible to everyone around me. Credit: Stephen Johnson ...

You may remember them from the summer, when Tea—where women could anonymously rate and discuss men under the pretense of helping each other safely navigate dating—was the target of data breaches that exposed users' personal information. From there, an app called TeaOnHer was launched for men and Tea faced a class action from users who were upset about their private data being easily accessible to hackers. Whether you remember them or not, they're gone now—sort of. Apple has yanked them from the App Store. The App Store removal of Tea and TeaOnHerTea was arou...

OpenAI has officially entered the browser wars. On Tuesday, the company announced Atlas, a new web browser with ChatGPT integration. At the moment, it's Mac-only, but I wouldn't recommend even my Apple friends jumping on board immediately—at least not without understanding the underlying risks. Atlas' AI web browsing If you've already used other AI browsers, like Perplexity's Comet, Atlas is going to feel familiar. In fact, that's also likely true if you've used any web browser before: Atlas is built on Chromium, the engine that powers browsers like Google Chrome, Microsoft Edge, and Opera. That means the core mechanics of Atlas are fairly standard; there's nothing particularly revolutionary happening here when it comes to sorting tabs or the browsing experience itself. The same is true ...

The guidelines from public health organizations tell you to aim for at least 150 minutes of “moderate” exercise each week, and that each minute of “vigorous” exercise counts double. That raises the question: What the hell is “moderate” exercise? How do you know when you’re doing it? Scientists measure METs, but you don't have to If you have any kind of smartwatch or fitness tracker, it may try to tell you that "moderate" exercise occurs at a certain heart rate. This isn't actually the case. The scientists who came up with the exercise guidelines didn't use heart rate as their guide. Instead, they used charts that measured how many "METs," or metab...
