Source of Martian methane and unique account of the origin of forms in plant and animal body plans

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 - A majestic new image from the Hubble Space Telescope reveals billowing waves of glowing gas and dust at the heart of a bright and active star-forming nebula in deep space. See article.
g Abodes - A new study indicates that methane in the atmosphere of Mars lasts less than a year. Methane is replenished from localized sources that show seasonal and annual variations. This pattern of methane production raises questions as to whether the methane comes from geological activity - or biological processes. See article.
g Life - A new paper published in the International Journal of Astrobiology is providing a unique account of the origin of forms in plant and animal body plans. The model is not based on genetic code or natural selection, and could provide new insights into the origin and evolution of life on our planet. See article.
g Message - Here’s an interesting interview of Jill Tarter, the director of the SETI Institute, by The Montreal Mirror from 2002. See article.
g Cosmicus - Medical devices being developed to help deliver health care to astronauts in space might also benefit patients on Earth. See article.
g Learning - He has spent much of his life charting human folly, but scientist Tim Flannery remains a determined optimist. He talks to Peter Munro about love, skeletons and his latest book. See article.
