A son of friends of mine has made a scientific discovery that is making the rounds of the scientific journals, and travelling through the web. You may have heard about it--women's hands are dirtier and have much more bacteria than men. This is despite the fact that women wash their hands significantly more often than men. Here's a link to one of the many articles:
Noah Fierer, who is the lead researcher on this, is predictably brilliant and insightful, given his genetic heritage. His parents are justifiably beaming (while looking at their own hands in a new light.)
Nice work, Noah!
