    If you’ve ever seen a leopard seal in a film or documentary, chances are it was viciously tearing apart a penguin.

    Studies Reveal How Cells Distinguish Between Disease-Causing and Innocuous Invaders

    The specific mechanisms by which humans and other animals are able to discriminate between disease-causing microbes and innocuous ones in order to rapidly respond to infections have long been a mystery to scientists. But a study conducted on roundworms by biologists at UC San Diego has uncovered some important clues to finally answering that question.
