Studying microbialites and why radio waves favored over optical signal

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 - Astrobiology Magazine Field Research Editor Henry Bortman recently spent a week in British Columbia with scientists from the Pavilion Lake Research Project. Scientist-pilots studied the microbialites in Kelly Lake in submersible vehicles and, as described in this report, scientist-scuba divers collected samples for lab analysis. See article.
g Message - While advanced civilizations might be tempted to use optical means such as lasers to send information between the stars, there are some good reasons that nearly all the major Search for Extraterrestrial Intelligence experiments are looking for radio waves instead. See article.
g Cosmicus - Astronomers have discovered the first known Trojan asteroid that shares an orbit with Earth. See article.
