A superfluid vortex controlled in a lab is helping physicists learn more about the behavior of black holes.A whirlpool generated in helium cooled to just a fraction above absolute zero mimics the gravitational environment of these objects to such high precision that it's giving unprecedented insight into how they drag and warp the space-time around them. "Using superfluid helium has allowed us to study tiny surface waves in greater detail and accuracy than with our previous experiments in water," explains physicist…

Image via Universal Pictures It wasn’t until recently that mimicry movies entered mainstream cinema. Revolutionary filmmaker Jordan Peele brought the terrifying concept of hostile doppelgängers to life in Us, a story following the Wilson family, everyday Americans who find themselves targeted by aggressive, murderous doppelgängers. Although Peele revitalized the niche sub-genre, other movies resembling Us in likeness dominated the late ’80s and ’90s. There aren’t a lot of mimicry movies to choose from, since the…

Scientists have discovered a clever mimicry trick used by some bats: they'll buzz like hornets when they think they're under threat from predators, giving the sonic impression they're more dangerous than they actually are.  It's the first time behavior like this has been recorded in mammals, but it happens elsewhere in the animal kingdom – such as when the wings of moths are patterned to appear like the insect is actually a different, much more dangerous species. The technical term for it is Batesian mimicry.The team…
