The Symmetry of Sleep

The World Science Festival is going to kick off on Wednesday in New York (I'll be speaking Thursday on a panel, on telling the stories of science in print and online.) The festival organizers have been publishing a blog on some of the topics that will be explored next week. Riffing on the session on sleep, I've just contributed a piece on some wonderful recent research on what it means for us to be asleep and to be awake--and the surprising porous wall that divides the two states of mind. Check it out.
