Science Ask Us Anything What'Jurassic Park' got wrong about venomous dinosaurs And what did'Spinosaurus' really do with that sail? Dilophosaurus didn't have a frill or spit venom. Breakthroughs, discoveries, and DIY tips sent six days a week. We all know dinosaurs were scary. While not strictly a dinosaur, the ancient shark was four times longer than the biggest great white. Now, imagine one of those big bad dinos had venom. That'd be the last thing we need, but it very well could've been a reality. In a new episode of's Ask Us Anything podcast, we dig into the fossil record to see just how likely a venomous dinosaur would've been.

The framework includes proposals for child privacy protections, fewer restrictions around data center buildout and vague ideas about IP licensing. The White House has announced a new AI policy framework that calls for Congress to craft federal regulation that overrules state AI laws. The Trump administration has made multiple attempts to overrule more restrictive state-level AI regulation, but has failed so far, most notably in the passing of the "One Big Beautiful Bill." The framework focuses on a variety of topics, covering everything from child privacy to the use of AI in the workforce. "Importantly, this framework can succeed only if it is applied uniformly across the United States," The White House writes.

Nvidia's new AI upscaling gaming technology struck gamers as uncanny and off-putting. Developers don't seem to like it, either, but it could be "the default" in a few years. Nvidia announced a new version of its DLSS AI upscaling technology for its graphics cards earlier this week at its GPU Technology Conference (GTC), which it calls the Super Bowl of AI . But unlike previous versions of DLSS that used AI to improve frame rates in video games, DLSS 5 has a much more ambitious calling: using generative AI to make character faces in games look more realistic and detailed. The demonstration received sharp blowback on social media, with many finding the effect off-putting, reacting with outright disgust, and calling it yet another example of AI slop .

Microsoft is implementing a major Windows 11 reset focused on improving performance, reliability, and user experience following widespread user complaints about system quality and AI integration. PCWorld reports that Copilot's presence will be significantly scaled back, removing it from apps like Notepad, Snipping Tool, and Photos due to user pushback against excessive AI features. Expected improvements include enhanced system stability, repositioned Taskbar, better Start menu functionality, and a more responsive overall experience with tangible progress visible in preview builds. Over the past few months, Microsoft senior executives have quietly made a promise to me directly, as well as to other journalists: They're going to improve Windows.

The GPUs were placed in servers that were supposed to be shipped from Taiwan to companies in Southeast Asia. The US Attorney's Office for the Southern District of New York has charged three people with illegally exporting NVIDIA GPUs to China in violation of the Export Control Reform Act. NVIDIA's chips have become a critical component in the rush to train and run increasingly complex artificial intelligence models, one the US has sought to manipulate with export controls and profit-sharing schemes with NVIDIA. The three people, Yih-Shyan Wally Liaw, Ruei-Tsang Steven Chang and Ting-Wei Willy Sun, two employees and one contractor working for US IT company Super Micro Computer, allegedly circumvented export control laws via a multi-step scheme that involved creating fake orders for servers with NVIDIA chips from Southeast Asian companies, that were then secretly sent to China. The plan involved paying a logistics company to repackage the servers in Taiwan, staging dummy servers to be inspected by Super Micro Computer's compliance team and falsifying records so Liaw, Chang and Sun's employer was unaware where the servers were actually being sent.

The home of the US Air Force's nuclear bomber fleet was repeatedly invaded by a swarm of mysterious drones that could not be stopped by the military's jamming technology. Officials at Barksdale Air Force Base in Louisiana confirmed to the Daily Mail that the base detected'multiple unauthorized drones' entering restricted airspace between March 9 and March 15. The first incident involving a single'unmanned aerial system' triggered a shelter-in-place order and terror alert amid reports from the FBI of potential drone attacks on US soil. However, an internal military briefing document has reportedly revealed that later incidents involved swarms of 12 to 15 drones entering the base's no-fly zone .
