Luis Hueso, the CICnanoGUNE researcher, together with researchers from the University of Cambridge, among others, has developed a new technology in the magnetic cooling of chips based on the straining of materials. Compared with the current technologies, this advance enables the impact on the environment to be lessened. The work has been published recently in the prestigious journal Nature Materials.

Researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) have long understood that using energy more efficiently can be just as beneficial as finding new ways to produce energy more efficiently.
On Feb. 7, NREL Director Dan Arvizu and a blue-ribbon panel of 20 energy experts drove that message home, declaring that the United States can double its energy productivity by 2030 — and do so in ways that bolster the nation's economy.
Scientists from the U.S. Department of Energy's National Renewable Energy Laboratory and other labs have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices.
A paper on the new technology, "Self-assembled Quantum Dots in a Nanowire System for Quantum Photonics," appears in the current issue of the scientific journal Nature Materials.
While the demand for ever-smaller electronic devices has spurred the miniaturization of a variety of technologies, one area has lagged behind in this downsizing revolution: energy-storage units, such as batteries and capacitors.
Now, Richard Kaner, a member of the California NanoSystems Institute at UCLA and a professor of chemistry and biochemistry, and Maher El-Kady, a graduate student in Kaner's laboratory, may have changed the game.
Between 2007 and 2010, the use of robotically-assisted hysterectomy for benign gynecologic disorders increased substantially, although, when compared with laparoscopic hysterectomy, the robotic procedure appears to offer little short-term benefit and is accompanied by significantly greater costs, according to a study appearing in the February 20 issue of JAMA.
If you want to read a mouse's mind, it takes some fluorescent protein and a tiny microscope implanted in the rodent's head.
Stanford scientists have demonstrated a technique for observing hundreds of neurons firing in the brain of a live mouse, in real time, and have linked that activity to long-term information storage. The unprecedented work could provide a useful tool for studying new therapies for neurodegenerative diseases such as Alzheimer's.
Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a "nano-shish-kebab," consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire. But looks can be deceiving, as the nanowire and nanosheets are actually a single, three-dimensional structure consisting of a single, seamless series of germanium sulfide (GeS) crystals. The structure holds promise for use in the creation of new, three-dimensional (3-D) technologies.
EAST LANSING, Mich. — Today's consumers switch between media forms so often – from TV to laptops to smart phones – that capturing their attention with advertising has gone, as one CEO explained, from shooting fish in a barrel to shooting minnows.
CAMBRIDGE, Mass. — Your smartphone snapshots could be instantly converted into professional-looking photographs with just the touch of a button, thanks to a processor chip developed at MIT.
The chip, built by a team at MIT's Microsystems Technology Laboratory, can perform tasks such as creating more realistic or enhanced lighting in a shot without destroying the scene's ambience, in just a fraction of a second. The technology could be integrated with any smartphone, tablet computer or digital camera.
For the first time, researchers have designed a special material interface that has been shown to add to and to improve the functioning of non-silicon-based electronic devices, such as those used in certain kinds of random access memory (RAM).
Under the auspices of the Comprehensive Nuclear-Test-Ban Treaty Organization, a worldwide monitoring system designed to detect the illegal testing of nuclear weaponry has been under construction since 1999.
The International Monitoring System is composed of a range of sensors, including detectors for hydroacoustic and seismic signals, and when completed, will include 60 infrasound measurement arrays set to detect low-frequency sound waves produced by an atmospheric nuclear detonation.
Adoption of electronic health records by family physicians has doubled since 2005, reaching 68 percent nationally in 2011.
According to analysis of two independent data sets, researchers found family physicians are adopting electronic health records at a higher rate than other office-based physicians and are likely to exceed 80 percent penetration by 2013 if the current trend continues.
ATLANTA- Lance Waller, PhD, chair of Biostatistics and Bioinformatics at Emory's Rollins School of Public Health, will present preliminary work that explores relationships between high-levels of air pollution exposure and health effects at a press briefing hosted by the American Association for the Advancement of Science on February 17, at 2 p.m. EST, in Boston.
You may have guzzled a half-liter bottle of water at lunchtime, but your food and clothes drank a lot more. The same half-liter that quenched your thirst also produces only about one square-inch of bread or one square-inch of cotton cloth.
In his Feb. 12 State of the Union address, President Obama singled out climate change as a top priority for his second administration. "We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence," he said. "Or we can choose to believe in the overwhelming judgment of science – and act before it's too late."
