Dust devils causing methane on Mars

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 - Methane on Mars has been taken as an indication that the planet could be geologically or biologically active. The origin of Mars methane is unknown, but a new theory suggests an unexpected source - dust storms and dust devils. See article.
g Life - Sixty-five million years ago, a mass extinction on Earth wiped out the dinosaurs. New research now indicates that a separate extinction event occurred shortly before that, triggered by volcanic eruptions that warmed the planet. See article.
g Intelligence - Lithium, introduced in the late 1940's, was the first "wonder drug" in psychiatry. It was the first medication treatment for the manic and depressive episodes of bipolar disorder and it remains among one of the most effective treatments for this disorder. See article.
