Why geologist tasted 2.6 billion-year-old water
CNN
If you discovered water that could be millions or billions of years old, would you taste it? Barbara Sherwood Lollar does it all the time. She's a geologist in the department of Earth Sciences at the University of Toronto, and collaborated with other researchers on analyzing water found in a Canadian mine in Timmins, Ontario.

Secrets of biological soil crusts uncovered
ScienceDaily
They lie dormant for years, but at the first sign of favorable conditions they awaken. This sounds like the tagline for a science fiction movie, but it describes the amazing life-cycles of microbial organisms that form the biological soil crusts (BSCs) of Earth's deserts. Now a research team with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has reported a unique molecular-level analysis of a BSC cyanobacterium responding to the wetting and drying of its environment.

Global cooling as significant as global warming
Newcastle University
A "cold snap" 116 million years ago triggered a similar marine ecosystem crisis to the ones witnessed in the past as a result of global warming, according to research published in Nature Geoscience. The international study involving experts from the universities of Newcastle, U.K., Cologne, Frankfurt and GEOMAR-Kiel, confirms the link between global cooling and a crash in the marine ecosystem during the mid-Cretaceous greenhouse period.

Early Mars atmosphere 'oxygen-rich' before Earth's
BBC News
Mars' atmosphere could have been rich in oxygen four billion years ago — well before Earth's air became augmented with the gas. That is the suggestion put forward by the author of a study in Nature journal, which outlines an explanation for differences between Mars meteorites and rocks examined by a robot rover. Dr. Bernard Wood said the idea fits with the picture of a planet that was once warm, wet and habitable.
