Here's part two of Stanford's Robert Sapolsky incredibly fascinating and illuminating lecture on primate sexuality (I posted part one last week). Sapolsky is a great lecturer: funny and engaging, and his material will make you rethink your relationship with your bits. Required viewing for anyone who has ever been horny, or who ever plans to be.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
