Earth-sized planet dense as lead and the search for ETI down under

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 - Were spinstars the universe's first polluters? The imprints of fast rotating massive stars have been found in the Milky Way's bulge. See article.
g Abodes - New observations of '55 Cancri e' indicate that the planet is 60 percent larger in diameter than Earth, but eight times more massive. The data also indicates that 55 Cancri e orbits so close to its star that it is baked to a temperature of 4,900 degrees F. See article.
g Life - Amphibian declines around the world have forced many species to the brink of extinction, are much more complex than realized and have multiple causes that are still not fully understood, researchers conclude in a new report. See article.
g Intelligence - Could veterans of war, rape victims and other people who have seen horrific crimes someday have the traumatic memories that haunt them weakened in their brains? In a new study, UCLA life scientists report a discovery that may make the reduction of such memories a reality. See article.
g Message - What are our friends south of the equator doing in the search for extraterrestrial intelligence? After all, the Northern Hemisphere only covers half of the galaxy. See article.
