Transistor laser functions as non-linear electronic switch, processor
The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and permit its use as a dual-input, dual-output, high-frequency signal processor. view more (2006-02-07)
Caffeine limits blood flow to heart muscle during exercise
In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude. view more (2006-01-16)
Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
Stretchable silicon could be next wave in electronics
Researchers at the University of Illinois at Urbana-Champaign have developed a fully stretchable form of single-crystal silicon with micron-sized, wave-like geometries that can be used to build high-performance electronic devices on rubber substrates. view more (2005-12-16)
Erotic images elicit strong response from brain
A new study suggests the brain is quickly turned on and "tuned in" when a person views erotic images. view more (2006-06-14)
New microchip technology for medical imaging biomarkers of disease
A collaboration between scientists at UCLA, Caltech, Stanford, Siemens and Fluidigm have developed a new technology using integrated microfluidics chips for simplifying, lowering the cost and diversifying the types of molecules used to image the biology of disease with the medical imaging technology, Positron Emission Tomography (PET). view more (2005-12-16)
UCLA engineers pioneer affordable alternative energy-solar energy cells made of everyday plastic
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science hope to meet the growing demand with a new and more affordable way to harness the sun's rays: using solar cell panels made out of everyday plastics. view more (2005-10-10)
Researchers create a broadband light amplifier on a chip
Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips. In such microchips, beams of light traveling through microscopic waveguides will replace electric currents traveling through microscopic wires. view more (2006-07-07)
The future of nutritional genomics is collaboration
Nutrigenomics experts worldwide have aligned, and they are calling for teamwork. José Ordovas, PhD, director of the Nutrition and Genomics Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University joined more than eighty other leading researchers in the fields of nutrition and genetics to co-author... view more...

Poor athletic performance linked to vitamin deficiency
Active individuals lacking in B-vitamins - including college athletes and other elite competitors - may perform worse during high-intensity exercise and have a decreased ability to repair and build muscle than counterparts with nutrient-rich diets. view more (2006-11-17)
Hawaii's anthurium growers cope with plant disease
A destructive pathogen is impacting Hawaii's production of anthuriums, a plant known for its heart-shaped flower and leaves. view more (2006-03-02)
Data processing joins fight to treat cancer
Laboratory technicians battling cancer want to improve diagnosis and treatment of the disease. But they are drowning in data from modern biological techniques. New Web-based software - validated in three European oncology hospitals - can extract potentially life-saving knowledge from such data in minutes. view more (2005-04-06)
New era in Process Technology: compact and more efficient
The process industry is constant factor in the Dutch economy and many innovations have happened in this sector. Those innovations form the subject of the inaugural speech of Professor Peter Jansens, professor of separation-technology at TU Delft, to be held on Wednesday 24 January. In his speech, the young professor will discuss subjects such as... view more... (2001-01-25)
Multitasking is hardest in the early morning
Multitasking seems to come easier for some and is virtually impossible for others, however new research shows that it is difficult for all in the late night and early morning. view more (2007-05-07)
