The above picture shows belly button bacteria growing in petri dishes, harvested from scientists, journalists and bloggers attending the ScienceOnline 2011 Conference. One may wonder why this is a thing, and the answer--as it usually is--is because of science, of course. The growing bacteria are part of the Belly Button Biodiversity project, which is also a thing, headed by North Carolina State University and the North Carolina Museum of Natural Sciences, and is part of a larger project with the goal of teaching humans the kinds of things that live in and on us. To gross us out. But, you know, for science.
