‘After contact, Then What?’ and protocluster of glaxies

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 - Astronomers have glimpsed a “protocluster” of galaxies as they appeared only a billion years after the Big Bang, making it the most distant galaxy cluster yet seen. See article.
g Life - Few scientific studies have drawn the level of criticism from the blogosphere and international scientific community lately as a study by scientists at the Stanford Synchrotron Radiation Lightsource and astrobiologists at NASA last month. The paper, titled “Bacterium that can grow using arsenic instead of phosphorus,” claims to have found a bacterium strain in California’s Mono Lake “which substitutes arsenic for phosphorus to sustain its growth.” See article.
g Cosmicus - The private spaceflight company Virgin Galactic scored another successful drop test of its SpaceShipTwo suborbital spacecraft Thursday, the latest in a series of smooth solo glides over the California desert for the commercial spaceship. See article.
g Aftermath - Though an older Web posting, article shows how little we’ve thought about this question.
