Space travel may be dangerous to brain

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Intelligence - Much has been made of our ancestors "coming down out of the trees," and many researchers view terrestrial bipedalism as the hallmark of "humanness." After all, most of our living primate relatives - the great apes, specifically - still spend their time in the trees. Humans are the only member of the family devoted to the ground, living terrestrial rather than arboreal lives, but that wasn't always the case. See article.
g Cosmicus - As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation - which would bombard astronauts on deep space missions to places like Mars - could accelerate the onset of Alzheimer's disease. See article.
g Aftermath - Philosophers and former politicians joined an elite group of scientists whose job it is to work out how to respond to signals from extraterrestrial intelligence. See article. Note: This article is from 2005.
