The Café Scientifique was very well done and informative tonight—so where were all you guys? Of course, what the event really meant was that it’s nearly 9:00, I’ve been running around all day, the alarm goes off tomorrow morning at 5:45AM, I teach at 8:00, and somehow I’ve got to explain MHC and T-cell receptors to a class full of sleepy students…and I’ve scarcely cracked the textbook today. So I’m tuning out for a while, to return again after a brief night’s rest.
