Habitable zone for 70 Ophiuchi AB and biofilm on T-Rex fossils

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 Stars - What is the habitable zone for the nearby binary 70 Ophiuchi AB?
g Abodes - New research shows that 40 million years ago the Earth was experiencing warmer seas with little or no ice on the planet. The finding could help scientists understand the effects of climate change on Earth today. See article.
g Life - In 2005, researchers thought they had discovered the remains of dinosaur blood vessels and cells protected inside the bones of a T-Rex. A new study shows that the soft tissue may be biofilms formed by bacteria. See article.
g Message -SETI research isn’t limited to a single facility listening to radio signals. Another dimension of the program is The Mega-Channel Extraterrestrial Assay, which searched the Southern Hemisphere's skies briefly during the 1990s. See article.
g Cosmicus -A privately funded rocket was lost on its way to space Saturday night, bringing a third failure in a row to an Internet multimillionaire's effort to create a market for low-cost space-delivery. See article.
g Aftermath - I offer this Web site entry on “exopolitics” only as a basis for us to think about how people might react once we know an extraterrestrial civilization exists.. Certainly many will give ufology more credence and make fantastical conclusions based upon images in the popular media. Question: How do we counteract this now? Obviously we want people discussing the topic of “exopolitics,” even if it’s in a vacuum. But how do we move beyond silly paranormal notions?
