The court has blocked the Federal Trade Commission's investigation into Media Matters, the media nonprofit that previously published research showing that ads appeared on X alongside neo-Nazi and other antisemitic content.

TCL D2 Pro Review: This Fast Palm-Scanning Smart Lock Is No Jedi Mind Trick

I love and hate smart locks. On one hand, it’s an undeniable treat to be able to get into my house even when I’ve forgotten my keys or make sure things are locked up when I’m away. But on the other, dead batteries, buggy software, and finicky wireless connections can evaporate that convenience, leaving me stuck on my porch, impotently stabbing my finger at a dead fingerprint sensor or waving my phone over a smart lock whose NFC reader just won’t respond.

If you have an iPhone, the Apple Watch is the best wearable to go with it. But what's the best Apple Watch to buy? Just a little while ago, this question was more complicated. In 2024, a court ruling dictated that Apple could no longer sell the latest watches—the Series 9, the Watch Ultra 2, and the Series 10—with a blood oxygen sensor. The medical technology company Masimo alleged that Apple had infringed on its patent. However, in August 2025, Apple redesigned the sensor via a software update,

Galaxy Watch Classic fan discovers bezel trick that looks like magic

Kaitlyn Cimino / Android Authority TL;DR A Reddit clip shows the Galaxy Watch 6 Classic’s bezel still works when held above the screen, thanks to magnetic sensing. The bezel uses a Hall sensor to detect changes in a magnetic field, rather than a mechanical connection. The same system is used on the latest Galaxy Watch 8 Classic. The rotating bezel is one of the Galaxy Watch Classic’s signature features, but it turns out that it doesn’t actually need to touch the smartwatch to work. It’s one

I love my grill, but standing over blazing flames in 90-degree weather isn't my idea of summer fun. Cooking indoors isn't much better -- the oven turns the whole house into a sauna, and firing up the gas range with the windows closed can hurt indoor air quality. That's where the air fryer comes in. These compact powerhouses cook quickly while using far less energy than a traditional oven, making them a perfect heat wave solution.
