Terrific range of topics, from the latest in medicine, bacteriology, CERN, astronomy, etc. Fairly detailed (frankly the recent report on antimatter and dark matter was a bit over my head!) it is a wonderful way to keep up to date in a variety of scientific fields. More technical than science info. for the general reader, but less technical than journal articles might be, this has been an excellent way for me, as a science teacher, to keep abreast of developments, which I can integrate into my physical science class. Also useful for answering some of the more exotic questions my quiz bowl team comes up with! Articles are comprehensive but not exhaustively so. I really enjoy this blog, and look forward to it, far more than the AP science blog or the Reuters science blog, though they also have merit.
