Ancestral Eve crystal and astrobiology's cool reception

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars – NASA's recently launched Solar Dynamics Observatory, or SDO, is returning early images that confirm an unprecedented new capability for scientists to better understand our sun's dynamic processes. These solar activities affect everything on Earth. See article.
g Abodes – An hour-long hailstorm has endangered a huge number of animal species and has disrupted the human traditions. It has been reported that the catastrophe is being attributable to disintegrating comet. See article.
g Life – Scientists are reporting discovery of what may be the "ancestral Eve" crystal that billions of years ago gave life on Earth its curious and exclusive preference for so-called left-handed amino acids. Those building blocks of proteins come in two forms - left- and right-handed - that mirror each other like a pair of hands. See article.
g Learning – New academic disciplines often get cool receptions. Women's Studies and Quantum Mechanics were considered either frivolous or fictional by many when they first appeared in university catalogs. In the late 1930s, the manuscript that Grote Reber wrote describing low-frequency emission from the Milky Way — a pioneering work that broke open the field of radio astronomy — was uniformly rejected by reviewers for the Astrophysical Journal. Fortunately, the editor decided to publish Reber's paper anyway. See article. Note: This article is from 2008.
