Gaping hole in universe, pure-tone radio signal and Federation of Astrobiology Organizations

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 - University of Minnesota astronomers have found an enormous hole in the universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies and gas, as well as the mysterious, unseen "dark matter." See article.
g Abodes - If you could pick up a rock from the surface of Mars, then the chances are it would be magnetic. And yet, Mars doesn't have a magnetic field coming from its core. These rocks are clinging to the signal of an ancient magnetic field, dating back billions of years, to the times when Mars had a magnetic field like Earth's. See article.
g Message - What would be a sign of alien intelligence? Forget mathematics — try a simple, pure-tone radio signal. See article.
g Cosmicus - The Federation of Astrobiology Organizations encompasses an ever widening set of individual astrobiology networks, associations, institutes, research groups, and societies; linking them together to assist the implementation of cooperative international activities. See article.
g Learning - Here’s a neat classroom activity: “Alien Safari.” New from NASA PlanetQuest, Alien Safari can be used in your classrooms or informal education settings to help kids discover some of the most extreme organisms on our planet, and find out what they are telling astrobiologists about the search for life beyond Earth.
g Imagining - Like first contact stories? Then be sure to read Isaac Asimov’s “The Gods Themselves” (published by Ballentine in 1972).
g Aftermath - Will we ever find a primer for decoding messages from extraterrestrials? Late last year, anthropologists who gathered for a major conference in Atlanta heard some news that will be sobering for SETI enthusiasts: It may be much more difficult to understand extraterrestrials than many scientists have thought before.
