Australian teams set new records for silicon quantum computing

October 13, 2014 11:30 am | by EurekAlert! | Comments

Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers. The teams created two types of quantum bits....

Researchers set speed record for fluorescent molecules

October 13, 2014 11:18 am | by EurekAlert! | Comments

Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal -- setting a speed record and making an important step toward realizing superfast light emitting diodes (LEDs) and quantum cryptography....

"Illusion coatings" make objects appear to be something else

October 13, 2014 11:11 am | by EurekAlert! | Comments

Developing the cloak of invisibility would be wonderful, but sometimes simply making an object appear to be something else will do the trick, according to Penn State electrical engineers. "Previous attempts at cloaking using a single metasurface layer ...

Metal nanoparticles can deform like a liquid

October 13, 2014 10:59 am | by EurekAlert! | Comments

A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration. The research team ...

'Smart' lithium-ion battery warns of fire hazard

October 13, 2014 9:20 am | by EurekAlert! | Comments

Stanford University scientists have developed a "smart" lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones....

NYC poised to end school cellphone ban

October 13, 2014 9:16 am | by KAREN MATTHEWS, Associated Press | Comments

New York City is preparing to end its ban on cellphones in schools, dooming an industry that sprang up near dozens of schools where teens could park their phones in a van for a dollar a day. Mayor Bill de Blasio - apparently the first mayor to have ...

Automated imaging system will aid world hunger

October 12, 2014 5:35 pm | by Georgia Institute of Technology | Comments

Researchers from the Georgia Institute of Technology and Penn State University have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The technique, believed to be the first of its kind ...

Observing the quantum behavior of light

October 10, 2014 2:55 pm | by EurekAlert! | Comments

This is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons — the particle complement of light waves — and sometimes only one photon at a time....

Researchers at University of California, San Diego School of Medicine have been awarded a $9.2 million grant to help modernize and transform how researchers share, use, find and cite biomedical datasets. The 3-year project, a collaboration with ...

Circuits that melt away when you're done

October 10, 2014 12:18 pm | by AVS: Science & Technology of Materials, Interfaces, and Processing | Comments

Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois at Urbana-Champaign. Early results demonstrate ...

Decay rates of radioactive substances are constant

October 10, 2014 11:47 am | by EurekAlert! | Comments

The distance between the Earth and the Sun has no influence on the decay rate of radioactive chlorine. You could ask: "And why should it anyway?", because it is well known that the decay of radionuclides is as reliable as a Swiss clock. Recently, US-American scientists ...

Leaky galaxies lead researchers to better understand the universe

October 10, 2014 11:06 am | by Ed Nakauchi, Technical Consultant, Orbel Corporation | Comments

Focusing on large, star-forming galaxies, researchers at the Johns Hopkins University were able to measure radiation leaks in an effort to better understand how the universe evolved as the first stars were formed. Sanchayeeta Borthakur, an assistant research scientist ...

Sensor uses radio waves to detect subtle changes in pressure

October 10, 2014 11:02 am | by EurekAlert! | Comments

Stanford engineers have invented a wireless pressure sensor that has already been used to measure brain pressure in lab mice with brain injuries. The underlying technology has such broad potential that it could one day be used to create....
