45-year physics mystery shows a path to quantum transistors

Posted: 05 Dec 2014 11:24 AM PST

An odd, iridescent material that's puzzled physicists for decades turns out to be an exotic state of matter that could open a new path to quantum computers and other next-generation electronics.

Successful launch of NASA's Orion spacecraft heralds first step on journey to Mars

Posted: 05 Dec 2014 11:23 AM PST

NASA marked a critical step on the journey to Mars with its Orion spacecraft during a roaring liftoff into the dawn sky over eastern Florida on Friday, Dec. 5, 2014, aboard a Delta IV Heavy rocket.

California's drought is the worst in 1,200 years, evidence suggests

Posted: 05 Dec 2014 09:43 AM PST

As California finally experiences the arrival of a rain-bearing Pineapple Express this week, two climate scientists have shown that the drought of 2012-2014 has been the worst in 1,200 years.

New technique offers spray-on solar power

Posted: 05 Dec 2014 09:43 AM PST

Pretty soon, powering your tablet could be as simple as wrapping it in cling wrap. Scientists have just invented a new way to spray solar cells onto flexible surfaces using miniscule light-sensitive materials known as colloidal quantum dots (CQDs) -- a major step toward making spray-on solar cells easy and cheap to manufacture.

Antarctica: Heat comes from the deep

Posted: 04 Dec 2014 11:26 AM PST

The water temperatures on the West Antarctic shelf are rising. The reason for this is predominantly warm water from greater depths, which as a result of global change now increasingly reaches the shallow shelf. There it has the potential to accelerate the glacier melt from below and trigger the sliding of big glaciers.

Lethal control of wolves backfires on livestock

Posted: 03 Dec 2014 11:25 AM PST

Researchers have found that it is counter-productive to kill wolves to keep them from preying on livestock. Shooting and trapping lead to more dead sheep and cattle the following year, not fewer. Wildlife biologists say that, for each wolf killed, the odds of more livestock depredations increase significantly.

Traces of Martian biological activity could be locked inside a meteorite

Posted: 02 Dec 2014 09:01 AM PST

Did Mars ever have life? Does it still? A meteorite from Mars has reignited the old debate. New research shows that Martian life is more probable than previously thought.

How early trauma influences behavior

Posted: 01 Dec 2014 09:51 AM PST

Traumatic and stressful events during childhood increase the risk to develop psychiatric disorders, but to a certain extent, they can also help better deal with difficult situations later in life. Researchers have studied this phenomenon in mice to learn how these effects could be transmitted to the next generation.
