Sovereign debt troubles in Europe underscore how important it is for the United States to control its own borrowing as its indebtedness reaches concerning levels, a senior Chinese official said. With China facing criticism for holding its currency in
Previously, artificial skin has been made from biomaterials such as collagen, polyglycolic acid, and chitosan. The fibrin-agarose skin, however, looks particularly promising. Prof. Jiménez Rodríguez, one of the researchers, stated "Definitively, we
Firstly, the D-Drive as pictured in our video is not a complete infinitely variable transmission system. At best, according to the engineering report, it is a cheap, innovative and potentially very useful primary component of an IVT.
Substation automation is not just about making an individual point smarter, but empowering communications across the grid. "The paradigm shift is that no longer is it simply, 'if this happens, switch this,'" said Wes Sylvester, the Director of Sm
Mr. Myhrvold played a slow-motion recorded video that showed what happened to a representative mosquito. As the insect flew, a sudden light beam struck it, disintegrating parts of its body into a plume of smoke. It fell, even as its wings continued t
Long before you even feel sick, a new Darpa-funded bio-sensor will know what ails you.
Because at the heart of it, what Steve has managed to do is create a gearbox that: · requires no clutch at all; · is infinitely variable - from top gear through neutral and even into reverse; and · d
Scientists have created microscopic robots out of DNA molecules that can walk, turn and even create tiny products of their own on a nano-scale assembly line.
Rather than destroying the cyanobacteria, the group has ingeniously reengineered their genetics, producing mutant strains that continuously secrete fatty acids through their cell walls.
From left, Jeffrey Long, Christopher Chang and Hemamala Karunadasa have discovered an inexpensive metal that can generate hydrogen from neutral water, even if it is dirty, and can operate in sea water. (Credit: Photo by Roy Kaltschmidt, Berkeley Lab
Now the Pentagon’s rolling out a revolutionary initiative to treat the condition: brain implants that one researcher likens to “replacement parts” for damaged gray matter.
The scientists are in the process of redesigning the graphene sheets with sticky ends that bind to titanium dioxide, which will improve the efficiency of the solar cells.
"The whiskers, feet, and scales of the dragon were above the water, and the dragon was several dozens of meters long." The dragon might have appeared more than once around Mount Long and Lake Yilong, thus explaining the choice of names for these pl
This airbrush technique deposits a well-studied material called P3HT to create spray-on transistors, which perform comparably to lab-standard equivalents made by spin coating. Credit: NIST
"Those of us who live outside Africa carry a little Neanderthal DNA in us," Pääbo says. The study estimates that between 1 and 4 percent of non-African DNA is inherited from these long-ago liaisons with our Neanderthal cousins.
Scientists have observed that there is some agent within frankincense which stops cancer spreading, and which induces cancerous cells to close themselves down. He is trying to find out what this is.
Low vitamin D levels have long been linked to a higher risk of MS. Experts suspect an expectant mother's lack of exposure to sunlight - the main source of vitamin D - may affect the fetus's central nervous system or immune system, and predispose it
Mammoths had a form of "anti-freeze" blood to keep their bodies supplied with oxygen at freezing temperatures. Nature Genetics reports that scientists "resurrected" a woolly mammoth blood protein to come to their finding.
The scope of the government’s involvement in bioweapons research, may be gauged from its estimated expenditure of $70 billion since 9/11 and the fact that, according to Ebright, more than 400 U.S. institutions are engaged in such work.
"The current carries dense, oxygen-rich water that sinks near Antarctica to the deep ocean basins further north," says co-author Dr Steve Rintoul from the Antarctic Climate and Ecosystems CRC and CSIRO's Wealth from Oceans Flagship.
allowing for the development of broadband wide-angle metamaterials that could enhance light collection in solar cells," he explains. "And the fact that the metamaterial has a wide-angle response is important because it means that it can 'accept'
Russia’s National Assoc. for Gene Security and the Institute of Ecological and Evolutional Problems has revealed that hamsters fed genetically modified (GM) foods produce grandchildren that are unable to produce fourth generation offspring.
Their results suggest that it will soon be possible to control plasmons, i.e. collective oscillations of electrons, purposefully in the graphene, by virtually establishing a lane composed of projections and humps for them. The results were published
Research into how Planarian worms can re-grow body parts could one day make it possible to regenerate old or damaged human organs and tissues
Uranium from seawater could provide power now if we were willing to pay 50% more per kwh for electricity
Horse racing on frozen rivers? Ice bowling? Activities last seen during Britain's Little Ice Age could once more be seen, researchers believe.
What is happening now is more economic drivers -- the fact that a third of a municipality's energy bill is moving and treating water. That's a big bill that you can attack with technology."
Stacked layers of oxidized graphene could be used to store hydrogen fuel for cars and other applications. So say researchers in the US who have made graphene-oxide frameworks (GOFs) that can hold roughly 1% of their weight in hydrogen. This value is
So how much smaller, faster and cheaper can computers go? Lots, if graphene, the nanomaterial of the new millennium, has anything to say about that. Discovered just a few years ago, graphene is only the thickness of one atom but it scores on str
The answer was within the next year or two. But today GE announced that they'll have an LED bulb replacement using Cree's LEDs available by the end of 2010. Now, let's be clear, this joint project from Cree and GE isn't as bright or as technologi
