Two for one in solar power: New process could revolutionize solar energy harvesting

Posted: 17 Nov 2013 12:57 PM PST

A process that could revolutionize solar energy harvesting has been efficiently demonstrated in solution for the first time.

Near-future heat and precipitation extremes predicted

Posted: 17 Nov 2013 12:56 PM PST

Unlike long-term climate predictions, forecasts about the next twenty to fifty years are fraught with major uncertainties. In spite of this, however, ETH-Zurich scientists have now managed to make projections about the future distribution of heat and precipitation extremes.

Volcano discovered smoldering under a kilometer of ice in West Antarctica: Heat may increase rate of ice loss

Posted: 17 Nov 2013 12:56 PM PST

A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.

Oxygen, phosphorus and early life on Earth

Posted: 17 Nov 2013 12:55 PM PST

Two billion years ago the Earth system was recovering from perhaps the single-most profound modification of its surface environments: the oxygenation of the atmosphere and oceans. This led to a series of major changes in global biogeochemical cycles.

Protein coding 'junk genes' may be linked to cancer

Posted: 17 Nov 2013 12:55 PM PST

By using a new analysis method, researchers have found close to one hundred novel human gene regions that code for proteins. A number of these regions are so-called pseudogenes, which may be linked to cancer. The expectation is now that this recently developed protein analysis method will open up a whole new field of research.

Safety in numbers? Not so for corals

Posted: 15 Nov 2013 11:14 AM PST

Traditionally, it was assumed that corals do not face a risk of extinction unless they become very rare or have a very restricted range. A team of scientists has revealed that global changes in climate and ocean chemistry affect corals whether scare or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most.
