Lava formed Martian ‘river’ channels and ETI’s message in a bottle

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 - New data indicates that at least one of the meandering channels on the surface of Mars was formed by flowing lava rather than liquid water. The study could help astrobiologists determine the likelihood of finding signs of past or present life on Mars. See article.
g Intelligence - Why do nice girls fall for bad boys? Let's shine the cold light of evolutionary psychology on the topic. See article.
g Message - Virtually all SETI experiments probe the skies looking for broadcasts from afar: radio or light signals that would tell us that someone as sharp-witted as ourselves is out there. But could it be that while we use binoculars to scan the cosmic sea, bottled messages have washed up unnoticed at our feet? See article. Note: This article is from 2004.
g Cosmicus - NASA chief Charles Bolden has asked senior managers to draw up an alternate plan for the space agency after members of Congress indicated they wanted to reject a White House proposal to hire private companies to ferry U.S. astronauts into orbit and beyond. See article.
g Aftermath - One of our natural tendencies when we make contact with strangers is to try to impress them. Sloppy dressers might polish their shoes for a job interview, hopeful suitors will wash their cars for a first date and prospective children-in-law will be on their best behavior in the presence of the parents of their intended. Wouldn’t we want to do the same in our first contact with ET? Lewis Thomas, in his book “Lives of a Cell,” suggests that if we want to impress an alien civilization, we should send "Bach, all of Bach, streamed out into space, over and over again." See article. Note: This article is from 2002.
