Dynamic Martian climate and the man who started modern SETI

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 - Physicists predict that trillions of years into the future, the information that currently allows us to understand how the universe expands will have disappeared over the visible horizon. What remains will be "an island universe" made from the Milky Way and its nearby galactic Local Group neighbors in an overwhelmingly dark void. See article.
g Abodes - New evidence shows that Mars' climate may have been much more dynamic than previously thought. The research has implications in understanding whether or not Mars could have supported life in its past. See article.
g Life - When he started compiling an online database of seashells 15 years ago, Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. See article.
g Message - Here’s a neat piece: an interview with Frank Drake, the astronomer and pioneer who flipped the "on" switch for Project Ozma, the first modern “SETI” project. See article. Note: The interview is from 2000.
g Learning - Join NASA and the Girl Scouts for an exciting summer residential program June 22-28, 2008, at NASA's Ames Research Center in Moffett Field, Calif. See article.
