Ah ha! So much for that whole "dirty-handed men" thing!

Article here. Betrays the "men tend to be less hygienic than women" stereotype, yes? Won't see this on JunkScience, er, I mean, LiveScience, any time soon. Excerpt:

'WASHINGTON – Wash your hands, folks, especially you ladies. A new study found that women have a greater variety of bacteria on their hands than men do. And everybody has more types of bacteria than the researchers expected to find.

"One thing that really is astonishing is the variability between individuals, and also between hands on the same individual," said University of Colorado biochemistry assistant professor Rob Knight, a co-author of the paper.

"The sheer number of bacteria species detected on the hands of the study participants was a big surprise, and so was the greater diversity of bacteria we found on the hands of women," added lead researcher Noah Fierer, an assistant professor in Colorado's department of ecology and evolutionary biology.'
