First animals fed by osmosis and an update on the Allen Telescope Array

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 - Evidence for rocky planets has been found in one of humanity's most beloved star clusters. See article. Note: This article is from 2007.
g Life - New research shows that the oldest complex lifeforms on Earth likely fed by osmosis. The organisms lived in the oceans more than 540 million years ago and absorbed nutrients through their outer membrane. The study provides new insight into the evolution of life on Earth. See article.
g Message - The possibility of intelligent life is what interests scientists at SETI. Using SETI's 42-antenna Allen Telescope Array in Northern California, they can listen in many directions for unusual radio signals coming from space. See article.
g Cosmicus - Quote of the Day: “The development of space colonies would free us from our gravitational hole and could lead to an advance for humanity equal in significance to the advance life made with its colonisation of dry land after spending three billion years confined to the seas and rivers of the world.” - Edward Ashpole, “The Search for Extra-Terrestrial Intelligence”
g Aftermath - Here’s an intriguing paper published in 2005 and translated from German for “Futurological Reflections on the Confrontation of Mankind with an Extraterrestrial Civilization.” See paper.
