Simulation of life on Mars and real-time evolutionary changes

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars - Astronomers have observed the motions of 28 stars orbiting the Milky Way’s most central region, which has helped them to study the supermassive black hole lurking there. See article.
g Abodes - Scientists have developed a simulation of Mars, which indicates that some form of lifecould exist below the surface of the Red Planet. See article.
g Life - For the first time scientists have observed in real-time evolutionary changes in one species driven by competition for resources from another. See article.
g Cosmicus - The success of a robotic drilling mission to search for subsurface life has demonstrated that robotic core sampling combined with remote laboratory analysis is both technically feasible and could be used for life detection on Mars. See article.
g Aftermath - Finding out that we are alone in the universe or a suburb of a huge village of other star folk - either alternative is mind boggling. See article. Note: This article is from 2003.
