Just a quick reminder–I’ll be keeping the contest for a free autographed copy of Microcosm till 5 pm this afternoon. Think of a question about E. coli (and what it can say about life itself), and get in the running for a signed book. I’ll post answers to the winning responses tomorrow by noon.
(Thanks to PZ Myers for a link from Pharyngula).
