House Democrats are demanding answers from the National Institute of Standards and Technology and urging it to halt rumored changes they say could undermine its mission. One of the US government's top scientific research labs is taking steps that could drive away foreign scientists, a shift lawmakers and sources tell WIRED could cost the country valuable expertise and damage the agency's credibility. The National Institute of Standards and Technology (NIST) helps determine the frameworks underpinning everything from cybersecurity to semiconductor manufacturing. Some of NIST's recent work includes establishing guidelines for securing AI systems and identifying health concerns with air purifiers and firefighting gloves. Many of the agency's thousands of employees, postdoctoral scientists, contractors, and guest researchers are brought in from around the world for their specialized expertise.

On TikTok, Chinese manufacturers are advertising signal-blocking weapons with the breezy cadence of consumer lifestyle advertising. "Pew, pew, pew!" a woman wearing sneakers and high-waisted pink trousers says cheerfully in a video uploaded to TikTok. She is standing on what appears to be an industrial rooftop while demonstrating how to use a black device resembling an oversized laser tag gun. "Jamming gun, good," she adds, flashing a thumbs up. These days, nearly any product imaginable is available for purchase on TikTok straight from Chinese factories, ranging from industrial chemicals to mystical crystals and custom pilates reformers.

New dinosaur discovered in Sahara desert was a horned'hell heron' 'Spinosaurus mirabilis' sported a 20-inch-tall'scimitar' on its head. Spinosaurus mirabilis stands along river's edge over its prey some 95 million years ago. A scimitar-shaped head crest and interdigitating teeth characterize this wading giant, one of the last-surviving spinosaurid species. Breakthroughs, discoveries, and DIY tips sent six days a week. Paleontologists still know comparatively little about fin-backed dinosaurs .

When a SpaceX rocket failure set the skies aflame over western Europe last February, no-one was sure if the debris was also polluting our atmosphere. Now scientists are directly linking the uncontrolled rocket re-entry to a plume of lithium measured less than 100km above Earth. It is the first time researchers have drawn a direct link between a known piece of space debris crashing to Earth and pollution levels. They warn that as SpaceX chief Elon Musk pledges to launch one million satellites in the coming years, this contamination could be the tip of the iceberg. The scientists were already investigating the problem of pollution from space debris when they realised a SpaceX Falcon 9 had failed in flight.

But the only native stork found in the U.S. is not out of the woods just yet. Breakthroughs, discoveries, and DIY tips sent six days a week. After over 40 years of recovery efforts, one population of the wood stork ()is being removed from the federal list of endangered and threatened wildlife. The large birds are as tall as 45 inches with wingspans that can reach 65 inches and are the only native storks in the United States. They are primarily found in the southeastern United States, where they feed on fish.

First discovered 20 years ago, the rare fossil combo reveals a Cretaceous meal in the making. Breakthroughs, discoveries, and DIY tips sent six days a week. A rare dinosaur fossil on display at the Museum of the Rockies in Bozeman, Montana, tells a gory story. The skull from a large plant-eating has a tooth lodged into it, indicating that it may have met its final moments as a meal. The tooth in question belongs to one of the most famous dinosaurs on earth-- .

Scout AI is using technology borrowed from the AI industry to power lethal weapons--and recently demonstrated its explosive potential. Like many Silicon Valley companies today, Scout AI is training large AI models and agents to automate chores. The big difference is that instead of writing code, answering emails, or buying stuff online, Scout AI's agents are designed to seek and destroy things in the physical world with exploding drones. In a recent demonstration, held at an undisclosed military base in central California, Scout AI's technology was put in charge of a self-driving off-road vehicle and a pair of lethal drones. The agents used these systems to find a truck hiding in the area, and then blew it to bits using an explosive charge.
