New research finds that online social behavior isn't replacing offline social behavior in the gaming community. Instead, online gaming is expanding players' social lives. The study was done by researchers at North Carolina State University, York University and the University of Ontario Institute of Technology.

UPTON, NY-Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have made the first 3D observations of how the structure of a lithium-ion battery anode evolves at the nanoscale in a real battery cell as it discharges and recharges. The details of this research, described in a paper published in Angewandte Chemie, could point to new ways to engineer battery materials to increase the capacity and lifetime of rechargeable batteries.

Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light detectors. Until now, it has been hard to couple light into these layered semiconductor systems. Scientists at Vienna University of Technology solved this problem. They used metamaterials, which are able to manipulate light in the terahertz range due to their special microscopic structure.

Large amounts of data are produced when industrial companies monitor their facilities. Sensors check temperature, pressure, power, or energy use data. "If you're scanning to the nearest second, it's easy to rack up several terabytes of information in under a week," says Dr. Olaf Sauer from the automation business unit at the IOSB. But often there is a lack of suitable methods to evaluate the information. "Today's operators use only about seven percent of this data for maintenance or protection from breakdowns," adds Sauer.

A year after responsibility for public health was transferred from the NHS to local authorities, the BMJ found numerous examples of councils disinvesting in a wide range of public health services, including those for substance misuse, sexual health, smoking cessation, obesity, and school nursing.

Much of this money is being used to support wider council services vulnerable to cuts, such as trading standards, domestic abuse services, housing, parks and leisure centres.

Crows completed 4 of 6 water displacement tasks, including preferentially dropping stones into a water-filled tube instead of a sand-filled tube, dropping sinking objects rather than floating objects, using solid objects rather than hollow objects, and dropping objects into a tube with a high water level rather than a low one. However, they failed two more challenging tasks, one that required understanding of the width of the tube, and one that required understanding of counterintuitive cues for a U-shaped displacement task.

TAIPEI, TAIWAN--The Phalaenopsis orchid, also known as the moth orchid, is the most important pot flower in terms of market value in the world's major floriculture markets. Because nitrogen significantly affects the growth and flowering of Phalaenopsis, nitrogen needs during flowering are of particular interest to growers.

Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements in process efficiency, the biofuel could supplement limited supplies of petroleum-based JP-10, and might also facilitate development of a new generation of more powerful engines.

Revelations of the extent of government surveillance have thrown a spotlight on the security – or lack thereof – of our digital communications. Even today's encrypted data is vulnerable to technological progress. What privacy is ultimately possible? In the 27 March issue of Nature, the weekly international journal of science, researchers Artur Ekert and Renato Renner review what physics tells us about keeping our secrets secret.

Researchers with the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bacteria for the production of advanced biofuels. The ionic liquid resistance is based on a pair of genes discovered in a bacterium native to a tropical rainforest in Puerto Rico.

The research was published online February 28 in the journal Analyst, a publication of the Royal Society of Chemistry. The work was supported by a National Science Foundation (NSF) Major Research Instrumentation Program (MRI) grant and by the National Science Foundation (NSF) and NASA Astrobiology Program, under the NSF Center for Chemical Evolution.

WEST LAFAYETTE, Ind. — Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety.

Researchers found that when paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules.

URBANA, Ill. – Using high-powered DNA-based tools, a recent study at the University of Illinois identified soil microbes that negatively affect ragweed and provided a new understanding of the complex relationships going on beneath the soil surface between plants and microorganisms.
