New type of microelectrode simplifies study of brain disorders

October 20, 2014 3:39 pm | by EurekAlert! | Comments

Researchers from the Perelman School of Medicine and School of Engineering at the University of Pennsylvania and The Children's Hospital of Philadelphia have used graphene -- a two-dimensional form of carbon only one atom thick -- to fabricate....

Unlocking the power of experimental superconducting computer chips

October 20, 2014 3:30 pm | by EurekAlert! | Comments

Computer chips with superconducting circuits — circuits with zero electrical resistance — would be 50 to 100 times as energy-efficient as today's chips, an attractive trait given the increasing power consumption of the massive data centers that power....

Scientists create possible precursor to life

October 20, 2014 3:04 pm | by EurekAlert! | Comments

How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not ...

1980s aircraft helps quantum technology take flight

October 20, 2014 1:08 pm | by EurekAlert! | Comments

What does a 1980s experimental aircraft have to do with state-of-the art quantum technology? Lots, as shown by new research from the Quantum Control Laboratory at the University of Sydney, and published in Nature Physics today. Over several years ...

New hydrogen mixture allows wild molecular interactions

October 20, 2014 1:03 pm | by EurekAlert! | Comments

Hydrogen—the most abundant element in the cosmos—responds to extremes of pressure and temperature differently. Under ambient conditions hydrogen is a gaseous two-atom molecule. As confinement pressure increases, the molecules adopt different states....

Transatlantic network allows faster data exchange between US and Europe

October 20, 2014 12:55 pm | by EurekAlert! | Comments

Scientists across the U.S. will soon have access to new, ultra high-speed network links spanning the Atlantic Ocean, thanks to a project currently underway to extend ESnet (the U.S. Department of Energy's Energy Sciences Network) to London....

Light switches help convert carbon dioxide into organic substances

October 20, 2014 12:50 pm | by EurekAlert! | Comments

Diatoms play an important role in water quality and in the global climate. They generate about one fourth of the oxygen in the Earth's atmosphere and perform around one-quarter of the global CO2 assimilation, i.e. they convert carbon dioxide....

Teachers know technology better than their students

October 20, 2014 12:40 pm | by EurekAlert! | Comments

Members of today's younger Net Generation aren't more tech savvy than their teachers just because they were born into a world full of computers. In fact, if it weren't for the coaxing and support of their educators, many students would never use....

New ways to create "smart materials"

October 20, 2014 12:35 pm | by EurekAlert! | Comments

Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of New York University scientists has found. Their discovery points to new ways to create "smart materials"....

Switching on a laser by taking energy away

October 20, 2014 12:31 pm | by EurekAlert! | Comments

What started out as a mathematical oddity, has now become a new kind of laser technology. Two years ago, physicists at TU Wien predicted a paradoxical laser effect: Under certain conditions, a laser can be switched on not by supplying it with more energy....

Wobbling of a Saturn moon hints at what lies beneath

October 20, 2014 8:45 am | by EurekAlert! | Comments

Using instruments aboard the Cassini spacecraft to measure the wobbles of Mimas, the closest of Saturn's regular moons, a Cornell University astronomer publishing in Science, Oct. 17, has inferred that this small moon's icy surface cloaks either ...

Magnetic fields form cosmic jets of young stars

October 20, 2014 8:42 am | by EurekAlert! | Comments

Astrophysical jets are counted among our Universe's most spectacular phenomena: From the centers of black holes, quasars, or protostars, these rays of matter sometimes protrude several light years into space. Now, for the first time ever, an international team ...

Electricity access marginally related to climate change

October 20, 2014 8:39 am | by EurekAlert! | Comments

Improving household electricity access in India over the last 30 years contributed only marginally to the nation's total carbon emissions growth during that time, according to a new study published in the journal Nature Climate Change. "Energy access is fundamental....

Crystallizing the DNA nanotechnology dream

October 20, 2014 8:34 am | by EurekAlert! | Comments

DNA has garnered attention for its potential as a programmable material platform that could spawn entire new and revolutionary nanodevices in computer science, microscopy, biology, and more. Researchers have been working to master the ability....

New imaging technique helps resolve microbiology controversy

October 20, 2014 8:32 am | by EurekAlert! | Comments

The claim by microbiologist Derek Lovley and colleagues at the University of Massachusetts Amherst that the microbe Geobacter produces tiny electrical wires, called microbial nanowires, has been mired in controversy for a decade, but the researchers say ...
