Expanding searches for ETI into new realms and don’t eat your peas if you care about humanity’s future

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 - Anyone who knows a trilobite from an ammonite can tell you that the history of early life is a book written in rock. According to SETI Institute scientist Friedemann Freund, chapter one and perhaps chapter two may have been written at least in part, by the rocks themselves. Common rocks, he explains, such as gabbro and granite carry a payload of complex chemistry that may have played a dynamic role in life’s origin, and the co-evolution of life and Earths oxygen-rich atmosphere. See article. Note: This article is from 2003.
g Message - Searches for extraterrestrial intelligence are about to expand into new realms, thanks to new advances in technology — and new thinking. See article. Note: This article is a few years old.
g Cosmicus - If harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source - a source that may be on your dinner plate tonight. See article.
g Aftermath - If we hear from ET, not only can we expect his civilization to be an old one with a great time lag in correspondence, a SETI astronomer says. Could this limit the impact of extraterrestrial contact upon humanity? See article. Note: This article is from 2001.
