Bat-eating spiders are more common in the world than once believed. These spiders are found on all continents except Antarctica. Almost 90% of the web-building spider and tarantula species live in warmer […]
3-body problem gets 13 more possible solutions
Scientists have come up with 13 new solutions to the “three-body problem,” a situation in which three objects orbit each other in a pattern. The discoveries, which will help astrophysicists further understand planetary […]
Bunnies implicated in the demise of Neanderthals in Iberia
Excavations are shedding light on what might have been a significant factor in the demise of the Neanderthal: the inability to hunt small game. The remains of large animals are prevalent […]
