Spring has finally arrived in Northern California, and with it course assignments that require me to spend an inordinate amount of time searching for literature on PubMed. As a reminder for readers not constantly reminded of the glories of this website, PubMed is a catalogue of papers published by most of the worlds biomedical journals. For those of you with long memories, back in February I wrote a post highlighting some of the more unusual papers included in the 19 million scientific citations listed by PubMed. Since that first post, I've been keeping my eyes peeling for more epic examples of odd research that has, by one way or another, seen the light of publication.
Without further ado, here are just a few of the papers I've found with subjects that range from humorous, awkward, to just plain weird. Some of these papers were discovered (and shared) by members of my Twitter community, some I actively searched for, and some I came across in the course of a legitimate literature search. As with Part 1, some of these papers are not suitable for work, children, or those with weak stomachs and vivid imaginations - these I have marked: consider yourself warned.

NOTE: This last paper may be disturbing to people. But its a perfect example of the mind-boggling research that corporations fund for publication, and has also received quite a bit of press in the last month. I would be remiss if I didn't include it.

And that's all for now. Until next time, happy PubMed-ing!
