Computers don't really boot up any faster than they have in decades and that is due to limitations in electric currents (and ignoring the bloated software rolled out after every new chip), which are also a significant power drain.

The solution may be on the horizon. A team has created a room-temperature magnetoelectric memory device, equivalent to one computer bit, that could lead to next-generation nonvolatile memory: magnetic switchability, in two steps, with nothing but an electric field. When data can be encoded without current - for example, by an electric field applied across an insulator - it requires much less energy and that means low-power, instant-on computing is a reality.

There is a running joke in America that there are three times as many people in the U.S. claiming to be Irish as there are actual people in Ireland. 

Though it's nice to claim to be Irish because of a last name, America is a melting pot. And it is so melted that the genetic ancestry of racial and ethnic groups varies significantly even across different geographic regions in the United States. A paper in the American Journal of Human Genetics, researchers analyzed the genomes of more than 160,000 African-Americans, Latin-Americans and European-Americans, providing insights into the subtle differences in genetic ancestry across the United States. 

Climate change impacts could mean uncertain transformations of global agriculture systems by 2050, according to a new paper from the International Institute for Applied Systems Analysis. 

A new paper has found that inhibiting or blocking stem cells ability to make a specific decision, leads to better cell growth and could lead to defined ways to differentiate stem cells.

Th authors say their research is the first comprehensive analysis of a pathway important for stem and cancer cell decisions known as Erk. As a result, they hope the work could contain clues to cancer treatment as well as helping to establish a platform to make stem cell treatments for gut related disorders like the pancreas or the liver. 

Despite a malfunction that ended its primary mission in May 2013, the Kepler spacecraft is still alive and working and its data has found a new "super-Earth".

NASA's Kepler spacecraft detected planets by looking for transits, when a star dims slightly as a planet crosses in front of it. The smaller the planet, the weaker the dimming, so brightness measurements must be precise and that requires maintaining a steady pointing. Kepler can't really do that any more, its primary functionality came to an end when the second of four reaction wheels used to stabilize the spacecraft failed. Without at least three functioning reaction wheels, Kepler couldn't be pointed accurately.

In the former mining area Herrerias in Andalusia, the deep waters of Pit Lake Guadiana show extremely high concentration of dissolved carbon dioxide (CO₂). 

Levels are so high that if it were to bubble up, human beings close-by would be jeopardized. To demonstrate a possible fix, scientists of the Spanish Institute of Geology and Mining, the University of the Basque Country (UPV/EHU, Bilbao) and the Helmholtz Centre for Environmental Research (UFZ) constructed a pilot plant for degassing.

A fountain pulls deep water through a pipe to the surface, where the gas can escape from the water. The buoyancy produced by the bubbles provides the energy required for driving the flow.
