Blogger Jason Kottke took a look at NASA's press release, which touts "an astrobiology finding that will impact the search for evidence of extraterrestrial life" (astrobiology, besides being a cool word, is "the study of the origin, evolution, distribution and future of life in the universe"), and decided to investigate further by looking at the participants' resumes. So who are the participants?
A geobiologist who's written about "geology and life on Mars";
an oceanographer who's done extensive work on arsenic-based photosynthesis;
a biologist examining Titan, the largest moon of Saturn, and its similarities to early Earth;
and an ecologist investigating the "chemistry of environments where life evolves."
