North Atlantic right whales, a beleaguered species of fewer than 400 individuals, gave researchers new reason to hope this winter off the coast of Georgia.

A new study from the University of Georgia shows that many things marked by deer glow under ultraviolet light, and could impact our understanding of how they communicate.

Gliselle Marin joins the “Bat-a-thon,” a group of 80-some bat researchers who converge on Belize each year to study these winged mammals.

The snake-like amphibian is native to Brazil. Researchers say the milk in many ways resembles that produced by mammals.

A 125-million-year-old fossil from the early Cretaceous shows the skeletons of a smaller mammal biting a larger horned dinosaur, suggesting a much more complex ancient food web.

Researchers have examined the genomes of 240 mammal species. The project reveals when mammals evolved, how some developed the ability to hibernate, and clues that may help explain humans' brains.
