This one you gotta go read --
This morning I got a question in e-mail, asking if I'd heard of a particular paper. Of course I had, it's a very fun bit of research...and then I realized I'd never mentioned it on the weblog before. I guess it's because it's focused entirely on the phylum Chordata, specifically one rather peculiar species—Homo sapiens. I probably just assumed nobody would be interested, because there aren't any arthropods or molluscs in it.
The paper is all about visualizing the arrangement of organs during coitus. People have tried to figure out how the pieces all fit together internally using cadavers and their imagination, by using a speculum and poking around with their fingers, and by clever tools, like hollow glass tubes shaped like a penis. This paper tries something different: the investigators had people have sex in an MRI tube, and snapped a few pictures while they were at it.
