Researchers have discovered that creating a graphene-copper-graphene “sandwich” strongly enhances the heat conducting properties of copper, a discovery that could further help in the downscaling of electronics.
SQUIDs, short for superconducting quantum...
Thin films of spin ice have been shown to demonstrate...
Over the first six months in their special, new, four-bedroom home in suburban Maryland, the Nisters, a prototypical family of four, earned about $40 by exporting 328 kW-h of electricity into the local grid, while meeting all of their varied energy needs. These virtual residents of the Net-Zero Energy Residential Test Facility (NZERTF) on the campus of NIST didn't have to skimp the creature comforts of 21st century living, either.
Scientists in the U.K. have proposed a new computer-based method of screening drugs that could be used to slow the aging process in humans. The proposed method uses gene expression data from “young” and “old” tissues to construct the cloud of molecular signalling pathways involved in ageing and longevity. It then evaluates the effects of a large number of drugs and drug combinations to emulate a youthful state for cells and tissues.
Ben Recht, a statistician and electrical engineer at the Univ. of California, Berkeley, looks for problems. He develops mathematical strategies to help researchers, from urban planners to online retailers, cut through blizzards of data to find what they’re after. He resists the “needle in the haystack” metaphor for big data because, he says, people usually don’t know enough about their data to understand the goal.
Very often, our memories must distinguish not just what happened and where, but when an event occurred, and what came before and after. New research from the Univ. of California, Davis, Center for Neuroscience shows that a part of the brain called the hippocampus stores memories by their "temporal context": what happened before, and what came after.
Oxygen-16, one of the key elements of life on earth, is produced by a series of reactions inside of red giant stars. Now, a team of physicists has revealed how the element’s nuclear shape changes depending on its state, even though other attributes such as spin and parity don’t appear to differ. Their findings may shed light on how oxygen is produced.
Scarcity of clean water is one of the most serious global challenges. In its spearhead program, a research center in Finland developed energy-efficient methods for reuse of water in industrial processes and means for recovering valuable minerals and materials from waste for recycling. Toward this purpose, rapid membrane-based tools were developed for identification of environmental pollutants.
Particle counters are used in a wide variety of industries. Researchers in North Carolina have developed a new thermal technique that counts and measures the size of particles, but is less expensive than light-based techniques. It can also be used on a wider array of materials than electricity-based techniques.
A research team in Austria has discovered that even simple systems, such as neutral atoms, can possess chaotic behavior. For the first time, researchers working at the Univ. of Innsbruck have been able to observe quantum chaos in the scattering behavior of ultracold atoms. This opens up new avenues to observe the interaction between quantum particles.
Using the VUV Free-Electron Laser FLASH at Deutsches Elektronen-Synchrotron in Hamburg, Germany, Lawrence Livermore National Laboratory researchers were part of a team that took a sneak peek deep into the lower atmospheric layers of giant gas planets such as Jupiter or Saturn.
The human relationship with microbial life is complicated. At almost any supermarket, you can pick up both antibacterial soap and probiotic yogurt during the same shopping trip. Although there are types of bacteria that can make us sick, a California Institute of Technology team is most interested in the thousands of other bacteria, many already living inside our bodies, that actually keep us healthy.
Researchers have created a new type of "ultracold" molecule, using lasers to cool atoms nearly to absolute zero and then gluing them together, a technology that might be applied to quantum computing, precise sensors and advanced simulations. Physicists are using lasers to achieve such extreme cooling, reducing the temperature to nearly absolute zero, or -273 C (-459 F)—the lowest temperature possible in the universe.
Pfizer Inc. said Wednesday that its blockbuster vaccine against pneumonia, blood and other infections met its goal of preventing illness in vulnerable elderly patients in a huge study required by U.S. regulators. The New York-based company's Prevnar 13 protects against 13 strains of pneumococcal disease, which can cause painful children's ear infections, pneumonia and life-threatening bloodstream infections.
Will one-atom-thick layers of molybdenum disulfide, a compound that occurs naturally in rocks, prove to be better than graphene for electronic applications? Recent research into phenomena occurring in the crystal network of this material show signs that might prove to be the case. But physicists in Poland have shown that the nature of the phenomena occurring in layered materials are still ill-understood.
Once the stuff of science fiction, driverless cars could be commercially available by decade's end. Under a California law passed in 2012, the DMV must decide by the end of this year how to integrate the autonomous vehicles onto public roads. That means the regulation's writers will post draft language regulations around June, then alter the rules in response to public comment by fall in order to get them finalized by the end of 2014.
A faster and less expensive form of radiotherapy for treating prostate cancer may come at a price, according to a new study by Yale School of Medicine researchers—a higher rate of urinary toxicity or urine poisoning. The standard therapy for prostate cancer is called intensity modulated radiation therapy (IMRT). Stereotactic body radiotherapy (SBRT) is a newer treatment that delivers a greater dose of radiation than IMRT.
