Renewable energy potential in every U.S. state, study shows

Posted: 01 Aug 2012 04:43 PM PDT

A new study of renewable energy's technical potential finds that every state in the United States has the space and resource to generate clean energy.

Writing graphics software gets much easier: New programming language yields code that’s much shorter and clearer -- but also faster

A new programming language for image-processing algorithms yields code that's much shorter and clearer -- but also faster.

Test flight over Peru ruins could revolutionize archaeological mapping

Posted: 01 Aug 2012 01:55 PM PDT

Archaeological sites that currently take years to map could be completed in minutes with a new system that uses an unmanned aerial vehicle that is currently being tested in Peru.

Breaking the barriers for low-cost energy storage: Battery could help transition to renewable energy sources

Posted: 01 Aug 2012 12:48 PM PDT

Scientists have developed an air-breathing battery that uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air -- a process similar to rusting.

New computational technique relieves logjam from massive amounts of data

Posted: 01 Aug 2012 12:48 PM PDT

It's relatively easy to collect massive amounts of data on microbes. But the files are so large that it takes days to simply transmit them to other researchers and months to analyze once they are received. Researchers have now developed a new computational technique that relieves the logjam that these "big data" issues create.

Wrinkled surfaces could have widespread applications

Scientists have created wrinkled surfaces with precise sizes and patterns.

Electromagnetic 'swamps' don't always bog electrons down

Posted: 01 Aug 2012 10:24 AM PDT

Scientists have designed a simple system to study how electrons travel through energy barriers instead of over them.

Dramatic miniaturization of metamaterials? Reluctant electrons enable 'extraordinarily strong' negative refraction

Posted: 01 Aug 2012 10:23 AM PDT

A new technique using kinetic inductance shows promise for dramatic miniaturization of metamaterials.

Lower hybrid drift waves in Earth's magnetosphere investigated

Posted: 01 Aug 2012 08:44 AM PDT

Scientists have detected and characterized lower hybrid drift waves, a special kind of plasma waves that develop in thin boundaries both in space and in the laboratory. The measurement of fundamental properties of these waves was possible when two of the spacecraft were flying very close to one another in the tail of Earth's magnetosphere. With wavelengths of about 60 km, these waves appear to play an important role in the dynamics of electrons and in the transfer of energy between different layers of plasma in the magnetosphere.

Theoretical physicists probe the Majorana mystery

Posted: 01 Aug 2012 08:35 AM PDT

Physicists close in on a subatomic particle that could enable the next generation of supercomputers and illuminate the inscrutability of cosmic dark matter.

A blue whirlpool in the river: Tranquil galaxy home to violent events

Posted: 01 Aug 2012 06:37 AM PDT

A new image taken with the European Southern Observatory's Very Large Telescope shows the galaxy NGC 1187. This impressive spiral lies about 60 million light-years away in the constellation of Eridanus (The River). NGC 1187 has hosted two supernova explosions during the last thirty years, the latest one in 2007. This picture of the galaxy is the most detailed ever taken.

Too cool to follow the law: Viscous materials do not follow standard laws below a sub-melting point threshold

Posted: 01 Aug 2012 06:36 AM PDT

So-called glass-formers are a class of highly viscous liquid materials that have the consistency of honey and turn into brittle glass once cooled to sufficiently low temperatures. Scientists have elucidated the behavior of these materials as they are on the verge of turning into glass. Although scientists do not yet thoroughly understand their behavior when approaching the glassy state, this new study, which relies on an additional type of dynamic measurements, clearly shows that they do not behave like more simple fluids, referred to as "activated" fluids.

Energy efficiency: New drywall building material can cut buildings' energy consumption by 40%

Posted: 01 Aug 2012 06:36 AM PDT

Researchers have developed gypsum boards able to store thermal energy that can reduce up to 40% of energy consumption of a building. The boards, that are combined with passive strategies (sunlight, natural airing), can reduce energy consumption in building up to 40% what contributes to mitigate the problem of energy crisis.
