Vampires!

So I saw "Eclipse" yesterday...no, don't get me wrong, I'm not a Twilight fan, but it was something to do and I have a running joke about having a crush on Edward, so it was obligatory to see the movie. It was pretty corny, I'll say that much, but that's to be expected. But what always gets me further is the fact that the science in these movies is horrendous. I mean, yes, they're not supposed to be realistic, but the anatomical constraints of transforming into a giant wolf in under a second are...ridiculous. At any rate, I figured I'd at least interject a little bit of science into the whole affair, with this paper I read a couple of months ago by population ecology graduate student: Enjoy!
