Water in Martian clouds and life beginning inside mica layers

Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Abodes - Martian clouds may contain less water than previously thought, according to a new NASA study. See article.
g Life - A new hypothesis describes how life may have begun in ancient oceans, protected inside layers of the mineral mica. These narrow, confined spaces may have provided the perfect conditions for the origin of biomolecules. See article.
g Cosmicus - Smaller Earth-like planets, some perhaps even having conditions for life, might be detected by astronomers with improved techniques, University of Hawaii-Manoa researchers say. See article.
g Aftermath - How is the search for life elsewhere reflected culturally in symbols that we recognize daily? One signpost invented to characterize the 'state of the internet' is the occasional change in the logo of the world's most popular search engine. How that doodle has come to recognize astrobiology seems to violate conventional wisdom on what is meant by tinkering with one's cherished brand recognition. See article. Note: This article is from 2004.
