UCSB physicists move 1 step closer to quantum computing

November 20, 2009

(Santa Barbara, Calif.) -- -- Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. The work is published online today on the Science Express Web site.

Projections of savings from health IT are baseless, Harvard researchers say

November 20, 2009

The increased computerization in U.S. hospitals hasn't made them cheaper or more efficient, Harvard researchers say, although it may have modestly improved the quality of care for heart attacks.

Rice ties in race for atomic-scale breakthrough

November 17, 2009

Everybody loves a race to the wire, even when the result is a tie. The great irony is the ultraprecise clocks that could result from this competition could probably break any tie.

Bigger not necessarily better, when it comes to brains

November 17, 2009

Tiny insects could be as intelligent as much bigger animals, despite only having a brain the size of a pinhead, say scientists at Queen Mary, University of London.

NIST demonstrates 'universal' programmable quantum processor

November 15, 2009

BOULDER, Colo. -- Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information
processor able to run any program allowed by quantum mechanics -- the rules governing the submicroscopic world -- using two quantum bits (qubits) of information.

Pushing light beyond its known limits

Scientists at the University of Adelaide have made a breakthrough that could change the world's thinking on what light is ca

Researcher: 'Optical biopsy' for breast cancer increasingly accurate

November 5, 2009

GAINESVILLE, Fla. -- Most biopsies following mammograms reveal benign abnormalities, not cancer.

How white is a paper?

October 22, 2009

Whiter paper and better color reproduction are examples of important competitive advantages on an international market. But how white is a paper? And why do vacation photos turn out so dark if you don't buy expensive photo paper?

Caltech scientists create robot surrogate for blind persons in testing visual prostheses

October 19, 2009

PASADENA, Calif. -- Scientists at the California Institute of Technology (Caltech) have created a remote-controlled robot that is able to simulate the "visual" experience of a blind person who has been implanted with a visual prosthesis, such as an artificial retina.

Key Laboratory of Quantum Information (CAS), University of Science and Technology of China has recently demonstrated a metropolitan Quantum Cryptography Network (QCN) for Government Administration in Wuhu, China.

Carnegie Mellon researchers save electricity with low-power processors and flash memory

October 14, 2009

PITTSBURGH -- Researchers at Carnegie Mellon University and Intel Labs Pittsburgh (ILP) have combined low-power, embedded processors typically used in netbooks with flash memory to create a server architecture that is fast, but far more energy efficient for data-intensive applications than the systems now used by major Internet services.

Kraken becomes first academic machine to achieve petaflop

October 8, 2009

The National Institute for Computational Sciences' (NICS's) Cray XT5 supercomputer -- Kraken -- has been upgraded to become the first academic system to surpass a thousand trillion calculations a second, or one petaflop, a landmark achievement that will greatly accelerate science and place Kraken among the top five computers in the world.

Corporations rethinking IT's role in cutting corporate costs, boosting productivity

October 5, 2009

HOBOKEN, N.J. -- The current recession has focused top information technology executives on cost-cutting, but they are not slashing jobs the way they did in previous economic downturns, according to a 2009 benchmark report commissioned by the Society for Information Management.

Denial of service denial

September 30, 2009

A way to filter out denial of service attacks on computer networks, including cloud computing systems, could significantly improve security on government, commercial, and educational systems. Such a filter is reported in the Int. J. Information and Computer Security by researchers from Auburn University in Alabama.

U-M physicists create first atomic-scale map of quantum dots

September 29, 2009

ANN ARBOR, Mich.---University of Michigan physicists have created the first atomic-scale maps of quantum dots, a major step toward the goal of producing "designer dots" that can be tailored for specific applications.
