Replicating evolution in the lab and the challenge of learning about worlds orbiting distant stars

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 - Imagine trying to learn everything you can about the Earth from a distance of billions or even trillions of kilometers. That's the challenge facing scientists who search for life on worlds orbiting distant stars. See article. Note: This article is from 2007.
g Life - Can evolution be played over again in the lab? A group of researchers plans to insert an ancient gene in a modern day bacteria and see if this gene will mutate back to its current-day form. The results will give insight into how unique the evolutionary path may be. See article.
g Intelligence - More Americans have given up their faith or changed religions because of a gradual spiritual drift than switched because of a disillusionment over their churches' policies, according to a new study released today which illustrates how personal spiritual attitudes are taking precedence over denominational traditions. See article.
g Cosmicus - Strange and exotic weapons are a recurring theme in science fiction. In some cases, weapons first introduced in science fiction have now been made a reality. Other science fiction weapons remain purely fictional, and are often beyond the realms of physical possibility. See article.
