Asteroid impact effect on Ediacarans and encouraging science careers

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 - Telescopes like Hubble and WISE are making observations of the comet Hartley 2 in preparation for its upcoming encounter with NASA's Deep Impact/EPOXI spacecraft. Studying comets like Hartley 2 can help astrobiologists determine if comets played a role in life's origins on Earth. See article.
g Life - Extreme cold and a giant asteroid impact in South Australia may have influenced the evolution of the Ediacarans, some of the earliest complex life on Earth, says new Australian research. See article.
g Message - Science fiction author David Brin offers a copy of his 1983 article “Xenology: The Science of Asking Who’s Out There”. While nearly three decades old, the information is still relevant and offers a good overview of fundamental astrobiological questions.
g Cosmicus - Will Russia again explore new worlds? See editorial.
g Learning - Middle and high school teachers and informal youth educators can receive up to 30 free copies of a new publication from Montana State University called "Is a career in extreme science for you?" See article.
