Animals like black-tailed prairie dogs (Cynomys ludovicianus) are under constant threat of being preyed upon from land and air by predators that include hawks, eagles, and coyotes. To cope with this danger, the social animals are in constant communication, including via so-called “contagious” displays, in which...

Tracing zoo birth records through three generations, the researchers found evidence for a decades-old theory of evolutionary biology: Mammals rely on some unknown physiological mechanism to manipulate the...

When I was applying to graduate school I was pretty naive, but I knew that I, at least, wanted to attend a program offering coursework...
