Origin & Evolution of Life: December 2010


"Life As We Know It", Redefined

Keith's note: Multiple, reliable sources within the Astrobiology community tell me that NASA's Astrobiology announcement tomorrow concerns Arsenic-based biochemistry and the implications for the origin of life on Earth, how it may have happened more than once on our planet, and the implications for life arising elsewhere in the universe. NASA has not found life on any other world.

That said, as a biologist, I have to say that this is exciting stuff. It shows that other biochemistries are possible - more than just "life as we know it" and that the possible places where "life" could exist in the universe are now much more numerous as a result. What other biochemistries are possible? I am certain we'll be hearing much more about this.

NAI collaborative tools were used to link people from around the globe

Using a suite of NAI collaborative tools, an NAI Workshop Without Walls on "Molecular Paleontology and Resurrection: Rewinding the Tape of Life" was held on November 8-10, 2010. Organized by scientists from the NAI teams at Georgia Institute of Technology and Montana State University, the workshop drew over 550 registrants from 31 US states and 30 other countries. Twenty-nine talks were presented using 21 different video conferencing rooms, Adobe Connect and phone. The presentations were recorded and are available online.
