'Lucy' probably needed to watch her back. Researchers led by the University of Iowa have described and named a new crocodile species that roamed a region in Africa more than 3 million years ago. The species is named Lucy's hunter, because it overlapped with the famed Lucy and her hominin kin and would have hunted them. Breakthroughs, discoveries, and DIY tips sent six days a week.

Breakthroughs, discoveries, and DIY tips sent six days a week. Approximately 290 million years ago, a carnivorous dinosaur stomping around present-day Germany had a tummy ache. The Paleozoic predator eventually vomited up its stomach contents, and then hopefully continued to live its best dino life. Unlike most ancient regurgitated meals, this particular mixture of half-eaten prey and digestive bacteria successfully fossilized into what's known as a regurgitalite. In 2021, paleontologists discovered the extremely rare find while working in the famous Bromacker Permian dig site, about 155 miles southwest of Berlin.

Roblox's AI-Powered Age Verification Is a Complete Mess Kids are being identified as adults--and vice versa--on Roblox, while age-verified accounts are already being sold online. Just days after launching, Roblox's much-hyped AI-powered age verification system is a complete mess. Roblox's face scanning system, which estimates peoples' ages before they can access the platform's chat functions, rolled out in the US and other countries around the world last week, after initially launching in a few locations in December. Roblox says it is implementing the system to allow users to safely chat with users of similar ages. But players are already in revolt because they can no longer chat to their friends, developers are demanding Roblox roll back the update, and crucially, experts say that not only is the AI mis-aging young players as adults and vice versa, the system does little to help address the problem it was designed to tackle: the flood of predators using the platform to groom young children.

Researchers theorize that they might be imitating snakes. Breakthroughs, discoveries, and DIY tips sent every weekday. A caterpillar-looking bug hangs out on a stem, minding its own business. Suddenly, forceps emerge, moving towards the creature. As soon as they touch the chunky insect, it hisses and whips its body side-to-side.
