Don’t expect little green men

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 - Nitrous oxide is released into the atmosphere could cause more damage to Earth's environment than carbon dioxide. Luckily, a previously unknown army of microorganisms helps transform the nitrous oxide into harmless nitrogen gas. See article.
g Life - UW-Madison's Clark Johnson, a geoscientist, has spent years thinking about and studying extraterrestrial life — where we are most likely to find it and what it is probably going to look like. Don't expect little green men. See article.
g Aftermath - Here’s an interesting book that is slated for June publication: “Contact with Alien Civilizations: Our Hopes and Fears about Encountering Extraterrestrials,” by Michael Michaud. This book describes a wide variety of speculations by many authors about the consequences for humanity of coming into contact with extraterrestrial intelligence. The assumptions underlying those speculations are examined, and some conclusions are drawn. As necessary background, the book also included brief summaries of the history of thinking about extraterrestrial intelligence, searches for life and for signals, contrasting paradigms of how contact might take place, and the paradox that those paradigms allegedly create. See review.
