Prof says aliens too far away and walking bacteria

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 - Astronomers are finding many new planets circling distant stars, but they have yet to find one like Earth. Studying the changing climate of Earth is an essential step in helping scientists identify similarly habitable worlds beyond our solar system. See article.
g Life - Bacterial biofilms can be extremely resistant to environment stresses, including antibiotics. Scientists studying biofilms have found that during the initial stages of formation, the bacteria can actually stand upright and walk.” The discovery of a new mechanism for bacterial motility is providing new information about the evolutionary history of these durable organisms. See article.
g Message - Here’s a famous 1960 article from Freeman John Dyson: “Search for Artificial Stellar Sources of Infrared Radiation.” See article.
g Cosmicus - Embryonic stem cells behave differently outside the pull of Earth's gravity, researchers suggest. These findings indicate why the human body deteriorates during long space missions, and warn that procreation in space may be fraught with peril. See article.
g Imagining - Aliens either are gods or too far to be a threat, a Yale astronomy prof says. See article.
