Ancient Mars Could Have Supported Life
sighted writes "NASA is announcing that analysis of a rock sample collected by the Curiosity rover shows ancient Mars could have supported living microbes. Scientists identified sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon in the powder Curiosity drilled out of a sedimentary rock near an ancient stream bed in Gale Crater last month. The announcement quotes Michael Meyer, lead scientist for NASA's Mars Exploration Program: 'A fundamental question for this mission is whether Mars could have supported a habitable environment. From what we know now, the answer is yes.'"

Sub-Ice Antarctic Lake Vida Abounds With Life
ananyo writes "It is permanently covered by a massive cap of ice up to 27 metres thick, is six times saltier than normal sea water, and at 13 C is one of the coldest aquatic environments on Earth — yet Lake Vida in Antarctica teems with life. Scientists drilling into the lake have found abundant and diverse bacteria, including at least one new phylum (full paper (PDF)). The find increases the chances that life may exist (or have once existed) on planets such as Mars and moons such as Jupiter's Europa."
