New system for detection of single atoms
Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough to discern the arrival of a single atom in less than one-millionth of a second, about 20 times faster than the best previous methods. view more (2009-05-18)
University of Miami physicist develops battery using new source of energy
Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have been able to prove the existence of a "spin battery," a battery that is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). view more (2009-03-12)
NRL scientists demonstrate efficient electrical spin injection into silicon
Scientists at the Naval Research Laboratory (NRL) have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon. view more (2007-07-17)
Mechanical motion used to 'spin' atoms in a gas
For the first time, mechanical motion has been used to make atoms in a gas "spin," scientists at the National Institute of Standards and Technology (NIST) report. view more (2006-12-11)
Vise squad: Putting the squeeze on a crystal leads to novel electronics
A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off. view more (2009-05-11)
Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately... view more... (2008-08-20)
Liquid crystal multilayer study promises improvements in manufacturing techniques for LCD's
In order to successfully fabricate a commercial Liquid Crystal Display, uniform orientation of the liquid crystal (LC) molecules is required. view more (2005-10-12)
On the Energy Trail: Berkeley Researchers Find New Details Following the Path of Solar Energy During Photosynthesis
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. view more (2008-04-28)
May hepatic granulomas be part of the histological spectrum of chronic hepatitis C?
While older large series of patients with hepatic granulomas have found sarcoidosis and tuberculosis to be the most common causes of hepatic granulomas, recent works have noted some patients with chronic hepatic C and hepatic granulomas and no other obvious associations. view more (2008-12-29)
NRL generates, modulates, and electrically detects pure spin currents in silicon
Scientists at the Naval Research Laboratory (NRL) have generated, modulated and electrically detected a pure spin current in silicon, the semiconductor used most widely in the electronic device industry. view more (2007-12-04)
The end of the end of ideology?
Despite the polarized nature of politics today, it appears that we all have the same underlying goals and behaviors: The pursuit of happiness, the American dream etc. view more (2007-05-18)
New on-off 'switch' triggers and reverses paralysis in animals with a beam of light
In an advance with overtones of Star Trek phasers and other sci-fi ray guns, scientists in Canada are reporting development of an internal on-off "switch" that paralyzes animals when exposed to a beam of ultraviolet light. view more (2009-11-19)
New invention that could change design of future memory storage devices
A research team at Singapore A*STAR's Data Storage Institute (DSI) has invented a new phase change material that has the potential to change the design of future memory storage devices. view more (2008-10-08)
Is Clostridium difficile-associated disease linked to use of common stomach medication?
Clostridium difficile-associated disease (CDAD), often associated with antibiotic use, is recognized as a major avoidable cause of illness and death in hospital patients. view more (2006-09-26)
New light detector
A novel prototype light meter has been developed by researchers in New York. Published today in the Institute of Physics journal, Measurement Science and Technology, this new retinal flux density meter will provide an affordable tool for measuring light at all levels and might ultimately lead to new standards to improve both energy efficiency and... view more...

Results promising for computational quantum chemical methods for drug development
New research, led by a Virginia Tech chemist, may someday help natural-products chemists decrease by years the amount of time it takes for the development of certain types of medicinal drugs. view more (2007-12-21)
Quantum computing spins closer
The promise of quantum computing is that it will dramatically outshine traditional computers in tackling certain key problems: searching large databases, factoring large numbers, creating uncrackable codes and simulating the atomic structure of materials. view more (2008-11-24)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
Through a light, darkly
A British physicist has come up with a way to reveal the shifting and shining colours that form in the dark spots where light waves interfere with each other. The patterns await experimental demonstration but computer-generated images are already illuminating new aspects of light that had until now remained in the shadows. When two waves meet... view more... (2002-10-18)
Bright light therapy eases bipolar depression for some
Bright light therapy can ease bipolar depression in some patients, according to a study published in the journal Bipolar Disorders. view more (2008-01-04)
