Skin microbes mapped

Beauty may be skin deep, but our body's outer coating has an ugly side, too: microbes. Researchers reported at the __American Society of Human Genetics__ linkurl:meeting;www.ashg.org/2008meeting/ in Philadelphia today (Nov. 13) that they have drawn up a head-to-toe map of the microorganisms crawling on our skin.
