Messaging to Extraterrestrial Intelligence and doomed binary systems

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Researchers who found the first hypervelocity stars escaping the Milky Way announced that their search also turned up a dozen double-star systems. Half of those are merging and might explode as supernovae in the astronomically near future. See article.
g Abodes - Recent data from the Spitzer Space Telescope has helped scientist determine what the “dust tail” of Earth looks like. The finding could help astrobiologists search for Earth-like planets because similar dust tails trailing behind extrasolar planets might actually be easier to spot than the planets themselves. See article.
g Life - Tyrannosaurus rex was far from a plodding Cretaceous era scavenger whose long tail only served to counterbalance the up-front weight of its freakishly big head. See article.
g Intelligence - The language we speak may influence not only our thoughts, but our implicit preferences as well. That's the finding of a study by psychologists at Harvard University, who found that bilingual individuals' opinions of different ethnic groups were affected by the language in which they took a test examining their biases and predilections. See article.
g Message - We’ve all heard of SETI, but what about METI — “Messaging to Extraterrestrial Intelligence,” or sending both scientific and artistic messages to the stars? See article. This article is from 2005.
g Cosmicus - NASA’s IceBite team is in Antarctica this month testing a new drill for a possible future mission to Mars. Team member Margarita Marinova will be writing a blog of their activities. If you have a question about the IceBite project, click the 'Ask a Scientist' button and send it to the scientists in the field. See article.
