A new study of the critters that live on the human body find that our skin is home to a much wider variety of bacteria than previously thought. While earlier findings had held that the human skin landscape skin is dominated mainly by Staphylococcus bacteria, new work published this week in the journal Science finds a much more diverse bacterial menagerie. The specific conditions on each body part -- from the dry deserts of a human forearm to the tropical jungles of the underarm to the often oily crease next to a nose -- play a large role in determining which bacteria will live there. We'll talk with one of the researchers about the study.
