A trio of theorists, including one from the NIST, have described how a future quantum computer could be used to simulate complex, high-energy collisions of subatomic particles. Given a working quantum computer—still under development—the algorithm could solve important physics problems well beyond the reach of even the most powerful conventional supercomputers.
A new set of computer models has successfully predicted negative side effects in hundreds of current drugs, based on the similarity between their chemical structures and those molecules known to cause side effects, according to a paper.
Computer scientists at the University of Glasgow are participating in a new project to develop a search engine which will draw its results from sensors located in the physical world.
The quantum computer is a futuristic machine that could operate at speeds even more mind boggling than the world's fastest supercomputers. Research involving physicist Mike Thewalt of Simon Fraser University offers a new step towards making quantum computing a reality, through the unique properties of highly enriched and highly purified silicon.
Researchers from Rice University and the University of California, Los Angeles unveiled a new data-encoding scheme that slashes more than 30% of the energy needed to write data onto new memory cards that use phase-change memory—a competitor to flash memory that has big backing from industry heavyweights.
Oracle has announced that it has entered into an agreement to acquire Collective Intellect, a company that specializes in cloud-based social intelligence solutions that enable organizations to monitor, understand, and respond to consumers' conversations on social media platforms such as Facebook and Twitter.
Lawrence Livermore National Laboratory researchers have for the first time identified a precise measurement of the amount of radiation damage that will occur in any given material. With a full understanding of the early stages of the radiation damage process, researchers are provided with better knowledge and tools to manipulate materials to our advantage.
U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail. Because international treaties forbid the detonation of nuclear test weapons, tools that can accurately depict an explosion are becoming critical for national defense.
Scientists at Rice University and the University of Texas MD Anderson Cancer Center have successfully profiled protein pathways found to be distinctive to leukemia patients with particular variants of the disease. Their research involved the creation of a new computational approach to identifying complex networks in protein signaling.
Police and security teams guarding airports, docks, and border crossings from terrorist attack or illegal entry need to know immediately when someone enter a prohibited area. A network of surveillance cameras is typically used to monitor these at-risk locations. Now, a system being developed by Massachusetts Institute of Technology can perform security analysis more accurately and in a fraction of the time it would take a human camera operator.
Research at Carlos III University in Madrid is developing an algorithm, based on ants' behavior when they are searching for food, which accelerates the search for relationships among elements that are present in social networks.
Northwestern University researchers are the first to discover that very different complex networks—ranging from global air traffic to neural networks—share very similar backbones. By stripping each network down to its essential nodes and links, they found each network possesses a skeleton and these skeletons share common features, much like vertebrates do.
Quantum computers are still years away, but a trio of theorists has already figured out at least one talent they may have. According to the theorists, physicists might one day use quantum computers to study the inner workings of the universe in ways that are far beyond the reach of even the most powerful conventional supercomputers.
In a new paper, Stanford University researchers describe a mathematical model they created that helps predict pragmatic reasoning and may eventually lead to the manufacture of machines that can better understand inference, context, and social rules.
As malware threats expand into new domains and increasingly focus on industrial espionage, Georgia Institute of Technology researchers are launching a new weapon to help battle the threats: A malware intelligence system that will help corporate and government security officials share information about the attacks they are fighting.
Through advanced computer modeling of house fires, mechanical engineers at the University of New South Wales are giving fire fighters a new suite of tools to investigate and battle dangerous blazes in time for the traditionally high-risk winter months. Beginning with an ignition point, the models can map how fires behave as they grow, accurately predicting their overall temperature and pinpointing dangerous hotspots that responding personnel should avoid.
Some 37 cameras shot 132 musicians running through the score of Gustav Holst's "The Planets” on the specially-blacked out stage at Watford Colosseum, just outside London, early this year. That footage has been used by a London museum to put the conductor's baton in visitors' hands, allowing guests to direct a virtual orchestra using 3D motion sensors.
A Sandia National Laboratories modeling study contradicts a long-held belief of geologists that pore sizes and chemical compositions are uniform throughout a given strata, which are horizontal slices of sedimentary rock. By understanding the variety of pore sizes and spatial patterns in strata, geologists can help achieve more production from underground oil reservoirs and water aquifers.
A group of Massachusetts Institute of Technology researchers will present a new mathematical framework that allows computer scientists to reason rigorously about sloppy computation. The framework can provide mathematical guarantees that if a computer program behaves as intended, so will a fast-but-inaccurate modification of it.
The search engine giant has spent the past two years poring through online encyclopedia Wikipedia, the CIA Factbook and other sources to expand a database of 12 million items that it picked up as part of its 2010 acquisition of Metaweb. On Wednesday it used this massive database to launch a new feature that provides a summary of vital information alongside main search results.
The U.S. government has been pushing doctors to e-prescribe, in part because it can be safer for patients. Now, more than a third of the nation's prescriptions now are electronic, and starting this year, holdouts will start to see cuts in their Medicare payments.
The main technical difficulty in building a quantum computer could soon be the thing that makes it possible to build one, according to new research from The Australian National University.
In a recent project that has challenged the notion that the best chip is the most accurate one, a research team has unveiled this week its prototype “inexact” computer chip. By allowing the chip to make a few mistakes, developers were able to slash the power consumption of the chip dramatically. The result is a chip at least 15 times more efficient than today’s technology.
A multiyear collaboration among Stanford University engineering departments uses some of the world's fastest supercomputers to model the complexities of hypersonic flight. Someday, their work may lead to planes that fly at many times the speed of sound.
