Public Release: 1-Aug-2013 Proceedings of the National Academy of Sciences Geoscientists unearth mineral-making secrets potentially useful for new technologies
Proteins have gotten most of the attention in studies of how organic materials control the initial step of making the first tiny crystals that organisms use to build structures that help them move and protect themselves. Virginia Tech researchers have discovered that certain types of sugars, known as polysaccharides, may also control the timing and placement of minerals that animals use to produce hard structures.

Public Release: 1-Aug-2013 Cell New insight into how brain 'learns' cocaine addiction
A team of researchers says it has solved the longstanding puzzle of why a key protein linked to learning is also needed to become addicted to cocaine. Results of the study, published in the Aug. 1 issue of the journal Cell, describe how the learning-related protein works with other proteins to forge new pathways in the brain in response to a drug-induced rush of the "pleasure" molecule dopamine.

Public Release: 30-Jul-2013 Applied Physics Letters Lawrence Livermore engineering team makes breakthrough in solar energy research
The use of plasmonic black metals could someday provide a pathway to more efficient photovoltaics -- the use of solar panels containing photovoltaic solar cells -- to improve solar energy harvesting, according to researchers at Lawrence Livermore National Laboratory.
Public Release: 29-Jul-2013 Nano Letters Tetrapod nanocrystals light the way to stronger polymers
Berkeley Lab researchers have developed advanced opto-mechanical stress probes based on tetrapod quantum dots (tQDs) that allow precise measurement of the tensile strength of polymer fibers with minimal impact on the polymer's mechanical properties. These fluorescent tQDs could lead to stronger, self-repairing polymer nanocomposites.

Public Release: 29-Jul-2013 Field test could lead to reducing CO2 emissions worldwide
An injection of carbon dioxide, or CO2, has begun at a site in southeastern Washington to test deep geologic storage. Battelle researchers based at Pacific Northwest National Laboratory are injecting 1,000 tons of CO2 one-half mile underground to see if the greenhouse gas can be stored safely and permanently in ancient basalt flows.

Public Release: 29-Jul-2013 Proceedings of the National Academy of Sciences How does hydrogen metallize?
Hydrogen is deceptively simple. It has only a single electron per atom, but it powers the sun and forms the majority of the observed universe. As such, it is naturally exposed to the entire range of pressures and temperatures available in the whole cosmos. But researchers still struggle to understand even basic aspects of its various forms under high-pressure conditions. New work makes significant additions to our understanding of this vital element's high-pressure behavior.

Public Release: 26-Jul-2013 Alternative-energy team wins US Department of Energy poster competition using only small words
Using only cartoons, drawings, photos, and the 1,000 most-commonly-used words in the English language, an alternative-energy team has taken first prize in a US DOE poster contest. The Penn State team's poster, titled "Powering Your Car with Sunlight," was selected as the overall winner out of 31 submissions. The poster explains how energy from the Sun is captured by plants and stored in plant cell walls as energy that could be used to power cars.

Public Release: 25-Jul-2013 Science Van Allen Probes pinpoint driver of speeding electrons
Researchers believe they have solved a lingering mystery about how electrons within Earth's radiation belt can suddenly become energetic enough to kill orbiting satellites. Thanks to data gathered from an intrepid pair of NASA probes roaming the harsh space environment within the Van Allen radiation belts, scientists have identified an internal electron accelerator operating within the belts.

Project Neptune: Specialized gas detection for nonproliferation
Sandia National Laboratories' Project Neptune aims to design a system capable of sensing, from among the loud signals of a lot of gases, the weak signals from specific gases that are signs of nuclear proliferation. The researchers believe their gas correlation technique will prove ideal for a simple, inexpensive sensor to monitor those few illusive gases.
