Food on Titan and why SETI prefers radio

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 - Astronomers have found a super-duper supernova. See article.
g Abodes - New calculations have suggested that Saturn’s moon Titan’s hydrocarbon lakes are loaded with acetylene, a chemical some scientists say could serve as food for cold-resistant organisms. 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. Note: This article is from 1996.
g Aftermath - While most depictions of extraterrestrials are confined to science fiction, nearly two-thirds of Americans believe that some form of alien life exists somewhere in the universe, according to a new survey. See article.
