It’s really difficult to figure out how old a free-living animal is.

Using two different radiocarbon dating approaches, Julius Neilsen and colleagues discovered that the giant Greenland shark may live as long as 400 years.

News stories on bees that live perilously close to the mouth of a volcano, diagnosing arthritis in dinosaur bones, and the evolution of the female orgasm, with David Grimm.
