Looking for the wrong kind of signals from extraterrestrials and oldest fossils of multicellar life

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 - Some scientists have thought that the Earth's Ice Age conditions 12,900 years ago were triggered by a meteor or comet. But a recent study suggests that the evidence pointing to the ancient impact is nothing more than fungus and other matter. See article.
g Life - Scientists say they've discovered cookie-shaped fossils in Gabon that may represent the earliest-known multicellular life, dating back 2.1 billion years. But when you go that far back, claims about fossilized life get complicated. See article.
g Message - For almost half a decade, the SETI project has unsuccessfully searched for alien life. However, SETI may be looking for the wrong kind of signals from extraterrestrials, believe two researchers. See article.
g Cosmicus - The UK Space Agency has announced it will develop and launch a miniature satellite to be used for inexpensive science missions in low-Earth orbit. See article.
