An international team of researchers has found what appears to be one of the secrets to evolutionary success for beetles—genes stolen from bacteria and fungi. In their paper published in Proceedings of the National Academy ...
Lamprey are blood-sucking vampire-like fish that attach to and eventually kill game fish, making them the bane of many a fisherman's existence. Like something out of a horror film, these parasites use radial rows of sharp ...
