Daejeon, Republic of Korea, September 29, 2013 -- For many decades, we have been relying on fossil resources to produce liquid fuels such as gasoline, diesel, and many industrial and consumer chemicals for daily use. However, increasing strains on natural resources as well as environmental issues including global warming have triggered a strong interest in developing sustainable ways to obtain fuels and chemicals.

In an advance that could dramatically shrink particle accelerators for science and medicine, researchers used a laser to accelerate electrons at a rate 10 times higher than conventional technology in a nanostructured glass chip smaller than a grain of rice.

The achievement was reported today in Nature by a team including scientists from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University.

WASHINGTON D.C. Sept. 27, 2013 -- As a modern culture, we crave artificial white lights -- the brighter the better, and ideally using less energy than ever before. To meet the ever-escalating demand for more lighting in more places and to improve the bulbs used in sports stadiums, car headlights and street lamps, scientists are scrambling to create better light-emitting diodes (LEDs) -- solid state lighting devices that are more energy efficient than conventional incandescent or fluorescent light sources.

A team from the University of Illinois at Urbana-Champaign and Northwestern University has devised a novel nuclear magnetic resonance imaging (MRI) technique that delivers a roughly 10¬nanometer spatial resolution. This represents a significant advance in MRI sensitivity -- modern MRI techniques commonly used in medical imaging yield spatial resolutions on the millimeter length scale, with the highest-resolution experimental instruments giving spatial resolution of a few micrometers.

Teams of international scientists have decrypted the effectiveness of two types of bacteria, which could be used in the future to help combat oil spill disasters.

According to a report written by scientists from the Helmholtz Centre for Environmental Research and the Helmholtz Centre for Infection Research in the peer-reviewed journal Applied and Environmental Microbiology, Alcanivorax borkumensis converts hydrocarbons into fatty acids which then form along the cell membrane.

The first scoop of soil analyzed by the analytical suite in the belly of NASA's Curiosity rover reveals that fine materials on the surface of the planet contain several percent water by weight. The results were published today in Science as one article in a five-paper special section on the Curiosity mission.

LOS ALAMOS, N.M., Sept. 26, 2013 — Within its first three months on Mars, NASA's Curiosity Rover saw a surprising diversity of soils and sediments along a half-kilometer route that tell a complex story about the gradual desiccation of the Red Planet.

Perhaps most notable among findings from the ChemCam team is that all of the dust and fine soil contains small amounts of water.

WASHINGTON, Sept. 26, 2013—Tracking blood flow in the laboratory is an important tool for studying ailments like migraines or strokes and designing new ways to address them. Blood flow is also routinely measured in the clinic, and laser speckle contrast imaging (LSCI) is one way of measuring these changes; however, this technique requires professional-grade imaging equipment, which limits its use.

CAMBRIDGE, MA -- Ceramics are not known for their flexibility: they tend to crack under stress. But researchers from MIT and Singapore have just found a way around that problem -- for very tiny objects, at least.

A good painter uses simple strokes of a brush to bring texture, contrast and depth to a blank canvas. In comparison, computer programs can have difficulty reproducing the complex and varied forms of brushstrokes, and often require painstaking effort to mimic a brief sweep of paint.

HUNTSVILLE, TX -- While research consistently estimates that one in every four women in higher education will experience rape or attempted rape during their college careers, limited proactive approaches to address the issue are found on Texas college campuses, according to the Crime Victims' Institute at Sam Houston State University.

URBANA, Ill. – Veterinarians and women's shelters can make it easier for abused women to decide to leave their homes, particularly when the abuser is using a beloved pet as part of a campaign to control his partner, reports a new University of Illinois study.

He made me stand there and . . . watch [him kill my cat]. And he was like: That could happen to you, one woman in the study said.

URBANA, Ill. – Many families struggle to afford basic non-food household goods, such as personal care, household, and baby-care products, according to a new nationwide Feed America study that benefited from assistance from the University of Illinois Family Resiliency Center (FRC).

"The study found that these families often make trade-offs with other living expenses and employ coping strategies in an effort to secure such essential household items as toilet paper, toothpaste, soap, or disposable diapers," said Barbara H. Fiese, FRC director and Pampered Chef Endowed Chair.

A team of Stanford engineers has built a basic computer using carbon nanotubes, a semiconductor material that has the potential to launch a new generation of electronic devices that run faster, while using less energy, than those made from silicon chips.

This unprecedented feat culminates years of efforts by scientists around the world to harness this promising material.
