Martian antifreeze and 600 million years for 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 Abodes - Even if an early Mars never got above freezing, the brine on its surface could have stayed liquid and supported life, a new study says. See article.
g Life - According to a Nature paper that's receiving some pickup (Reuters, CSM ) the history of life on earth may just have got roughly 15% longer. That may not sound a huge difference, but a 15% extension on life's lease adds up to 600 million years -- roughly equivalent to the time taken for animals to get from creepy little things that couldn’t even crawl to your pet cat. See article.
g Cosmicus - In a project designed to help NASA plan for a future mission to explore Jupiter’s moon Europa, researchers have begun testing an autonomous underwater vehicle, known as ENDURANCE, in the ice-covered waters of Antarctica’s Lake Bonney. The biggest problem they’ve run into so far? Bubbles. See article.
