Researchers mapped the mammoth family tree by extracting DNA from fossils. Also, scientists found some sessile animals living under Antarctica's ice shelf, and they're really cool.

Dolphins are one of the smartest animal species on Earth. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. But exactly how smart are they? Lori Marino...

Some species of bacteria have a wicked survival strategy: killing members of their own species or a closely-related one. There’s a lot we don’t know about it, but it's possible that someday we could potentially harness that knowledge to...
