Sexy Genes 

University of Illinois researchers say they've identified a few 'gay genes' on male chromosomes 7, 8, and (maternal) 10. I'm all for finding this sort of thing, although, as Graham points out, there are some potential downsides as well, so this is cool.

I'm less interested in a 'why am I gay' kinda way than in a 'how's it all work' one, and some of the details here are really fascinating. Why does the copy of 10 with the gene on it have to come from the mother, but not the rest? What about the stuff on X? And why, ferfuckssake, would it even occur to anyone anymore that "it is not believed to contain many genes" is even a vaguely acceptable reason to not look at Y?
