If you don't already subscribe to the daily round up and real time "peer review" of science coverage assembled by Charlie Petit at the MIT Knight Science Journalism Tracker, you are missing out on one of the Web's great science communication resources.

Things are also likely to get even richer at the Tracker. Charlie announced yesterday that the MIT Knight program is adding Paul Raeburn as a contributor to the round-up, reviewing coverage of medicine and health. Raeburn is a veteran of the AP, Business Week, and NPR. He's also a past president of the National Association of Science Writers.
