A TED talk at St Louis University by Brian Boutwell. The effects of nature and nurture.
Special note for JenDurham, who asked who Brian Boutwell was when I first posted an article by him not so long ago. Here y'are: this is who he is. I'm still more interested in what he says than who he is though. He's a bloke, a scientist, a husband. That's enough for me. Anyway, listen to this and you'll know as much about him as I do. Which is not much. But you'll know a fair bit about what's driving his research.
