Mars lake 'much like early Earth'
BBC News
The ancient lake environment found in Mars' Gale Crater could have supported microbes called chemolithoautotrophs — if they had been present. That is the conclusion of scientists after reviewing all the pictures and other data gathered in the deep impact bowl by Nasa's Curiosity rover. Chemolithoautotrophs do not need light to function; instead, they break down rocks and minerals for energy. On Earth, they exist underground, in caves and at the bottom of the ocean.

New evidence for assessing tsunami risk from very large volcanic island landslides
ScienceDaily
The risk posed by tsunami waves generated by Canary Island landslides may need to be re-evaluated, according to researchers at the National Oceanography Centre. Their findings suggest that these landslides result in smaller tsunami waves than previously thought by some authors, because of the processes involved.
