Earth analog to region on Titan and how cosmic rays affect life

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 - Experiments on board the ISS are helping scientists monitor how much radiation living organisms receive in orbit. The same experiments could also provide data on cosmic rays that will help us understand the origins of the universe. See article.
g Abodes - A region on Saturn's moon Titan has been found to be similar to the Etosha Pan in Namibia, Africa. See article.
g Intelligence - Tape measures. Rulers. Graphs. The gas gauge in your car, and the icon on your favorite digital device showing battery power. The number line and its cousins - notations that map numbers onto space and often represent magnitude - are everywhere. Most adults in industrialized societies are so fluent at using the concept, we hardly think about it. We don't stop to wonder: Is it "natural"? Is it cultural? See article.
