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.
