Seeing double: New study explains evolution of duplicate genes

April 8, 2014 2:18 pm | by Georgia Institute of Technology | Comments

From time to time, living cells will accidently make an extra copy of a gene during the normal replication process. Throughout the history of life, evolution has molded some of these seemingly superfluous genes into a source of genetic novelty, adaptation and...

Cheap solar power—at night

April 8, 2014 2:12 pm | by MIT Technology Review | Comments

New solar thermal technologies could address solar power’s intermittency problem.When the world’s largest solar thermal power plant—in Ivanpah, California—opened earlier this year, it was greeted with skepticism. The power plant is undeniably impressive....

Photos of the Day: 'Electronic skin' can store and deliver medicine

April 8, 2014 1:22 pm | by ECN Staff | Comments

Researchers from the University of Texas in Austin have developed a wearable device known as “electronic skin” that can store and transmit data and release drugs into the skin. The device is a bit like an electronic parfait — layers of stretchable nanomaterials in a tiny package....

Climate meeting to discuss future of fossil fuels

April 7, 2014 4:42 pm | by FRANK JORDANS, Associated Press | Comments

After concluding that global warming almost certainly is man-made and poses a grave threat to humanity, the U.N.-sponsored expert panel on climate change is moving on to the next phase: what to do about it. The Intergovernmental Panel on Climate Change, or IPCC, will meet next week....

Watching for a black hole to gobble up a gas cloud

April 7, 2014 4:30 pm | by EurekAlert! | Comments

Right now a doomed gas cloud is edging ever closer to the supermassive black hole at the center of our Milky Way galaxy. These black holes feed on gas and dust all the time, but astronomers rarely get to see mealtime in action. Northwestern University's Daryl Haggard has been closely watching the little cloud....

Iowa State scientist developing materials, electronics that dissolve when triggered

April 7, 2014 4:27 pm | by EurekAlert! | Comments

A medical device, once its job is done, could harmlessly melt away inside a person's body. Or, a military device could collect and send its data and then dissolve away, leaving no trace of an intelligence mission. Or, an environmental sensor could collect climate information, then wash away in the rain....

To bridge LEDs' green gap, scientists think small ... really small

April 7, 2014 4:19 pm | by EurekAlert! | Comments

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the "green gap," a portion of the spectrum where LED efficiency plunges, simulations at the U.S. Department of Energy's National Energy Research Scientific Computing Center (NERSC) have shown....

New algorithm aids in both robot navigation and scene understanding

April 7, 2014 4:12 pm | by EurekAlert! | Comments

Suppose you're trying to navigate an unfamiliar section of a big city, and you're using a particular cluster of skyscrapers as a reference point. Traffic and one-way streets force you to take some odd turns, and for a while you lose sight of your landmarks....

Helium ions may provide superior, better-targeted treatment in pediatric radiotherapy

April 7, 2014 4:10 pm | by EurekAlert! | Comments

For the first time, researchers have been able to demonstrate that the use of helium ions in radiation therapy could provide accurate treatment to tumours while helping to spare healthy organs. A treatment planning study to be presented at the ESTRO 33 congress today....

Self-assembled superlattices create molecular machines with 'hinges' and 'gears'

April 7, 2014 4:02 pm | by EurekAlert! | Comments

A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them....

Groundbreaking optical device could enhance optical information processing, computers

April 7, 2014 3:59 pm | by EurekAlert! | Comments

At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon....

Movies synchronize brains

April 7, 2014 3:56 pm | by EurekAlert! | Comments

When we watch a movie, our brains react to it immediately in a way similar to brains of other people. Researchers at Aalto University in Finland have succeeded in developing a method fast enough to observe immediate changes in the function of the brain even when watching a movie....

April 7, 2014 3:52 pm | by EurekAlert! | Comments

Researchers are blending technology with nature, as they present details on an iPad application to examine how young children are learning science skills in nature-themed outdoor play settings. Alan Wight, a doctoral candidate in the University of Cincinnati School of Education...

Twitter use linked to infidelity and divorce, MU study finds

April 7, 2014 3:49 pm | by EurekAlert! | Comments

Twitter and other social networking services have revolutionized the way people create and maintain relationships. However, new research shows that Twitter use could actually be damaging to users' romantic relationships. Russell Clayton, a doctoral student in the University of Missouri School of Journalism...
