Evidence that ancient Mars could have supported living microbes

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - An analysis of a rock sample collected by NASA's Curiosity rover shows ancient Mars could have supported living microbes. The sample came from sedimentary rock near an ancient stream bed and contained some of the key chemical ingredients for life. See article.
g Life - Last week, reports began to emerge that scientists had discovered a previously unknown bacteria in samples from Antarctica’s Lake Vostok. Word quickly spread throughout the blogosphere, but the bacteria in question is likely just a contaminant. See article.
g Message - Book alert: In “Is Anyone Out There?”, by Frank Drake, Dava Sobel, University of California astronomy and astrophysics professor Drake, aided by science journalist Sobel, responds to the title's classic question with an account of his career-long quest to gamer hard scientific data that might point to some answers. One of America's pioneer radio astronomers, Drake provides firsthand descriptions of breakthrough moments in the past 30 years of astrophysics - no encounters of any kind, just straightforward astrophysics with inconclusive experimental results. Drake's medium is science, his theory technical and his slightly anthropocentric conclusions more modest than those of the average UFO abductee.
