Live-blogging arsenic life. This is interesting on a number of fronts. The basic issue seems to be decided: no, arsenic can't substitute for phosphorus in DNA and didn't in the bacteria in which it was claimed to. What's almost more interesting to me is the process that Rosie Redfield used, blogging to think out the issue, then publishing on the Web before publishing in a journal. It's seemed to me that the Web is ideal for interacting on scientific issues, but the scientific community has been pretty slow to pick up on that.
