Researchers now suspect that the image literally tricks the brain into thinking that the observer is moving into a darkened space, like a cave or tunnel.

Now, scientists suspect that the massive predator may have been driven to extinction by a rival marine species: great white sharks.

Now, new research finds that the more complex the dance, the more likely the spiders are to find love.

It used its helmet head to bash rivals.]( (Wang et al., Science (2022)) Nearly 17 million years ago, a relative of modern giraffes that roamed northern China sported a thick, stumpy neck and a thick skull — perfect for sparring with rival males in headbutting battles. The newly-discovered giraffe relative, a now-extinct species named Discokeryx xiezhi, also had a bony, disk-like shield on the top of its skull, covered in a protective layer of keratin — the same type of tissue found in the horns of headbutters such as bulls and rams. The hard disk resembled a sort of squat helmet that sat atop the animal's head, scientists reported in a new analysis of several D. xiezhi fossils, published June 2 in the journal Science.

But if they do exist, they might be hanging out on Dyson spheres circling the husks of sunlike stars called white dwarfs scattered throughout the Milky Way, a new paper argues.
