Radio-using ETI ‘one in a million’

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 - Two of NASA's great observatories, the Spitzer and Hubble space telescopes, have teamed up to uncover a mysterious infant star that behaves like a strobe light. See article.
g Life - A new study shows that salmon may use the geomagnetic field to navigate across thousands of miles of open ocean to locate their river of origin. See article.
g Message - NASA’s Kepler mission has identified 2,740 planets orbiting other stars, but do any of them harbor intelligent life? Scientists at the University of California, Berkeley, have now used the Green Bank Telescope in West Virginia to look for intelligent radio signals from planets around 86 of these stars. While discovering no telltale signs of life, the researchers calculate that fewer than one in a million stars in the Milky Way Galaxy have planetary civilizations advanced enough to transmit beacons we could detect.
