Light-induced hormone surge points to benefits of light therapy
A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers. view more (2005-11-09)
Exposure to sunlight could reduce asthma
Australian researchers have found that exposure to measured doses of ultraviolet light, such as sunlight, could reduce asthma. view more (2006-10-26)
Small study points to addictive effects of frequent tanning
Frequent users of tanning beds may be getting more out of the experience than darker skin, according to researchers from Wake Forest University Baptist Medical Center. view more (2006-03-29)
Alzheimer's disease progresses more rapidly in highly educated people
High levels of education may help ward off Alzheimer's disease, but they also speed up its progression once developed, reveals research in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-02-16)
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)
Reversing and accelerating the speed of light
Physicist Costas Soukoulis and his research group at the U.S. Department of Energy's Ames Laboratory on the Iowa State University campus are having the time of their lives making light travel backwards at negative speeds that appear faster than the speed of light. view more (2006-07-24)
NASA's Chandra finds black holes are 'green'
Black holes are the most fuel efficient engines in the Universe, according to a new study using NASA's Chandra X-ray Observatory. view more (2006-04-25)
Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies. view more (2006-05-16)
Mood Lighting: Penn Researchers Determine Role of Serotonin in Modulating Circadian Rhythm
Researchers at the University of Pennsylvania School of Medicine have determined how serotonin decreases the body's sensitivity to light and that exposure to constant darkness leads to a decrease in serotonin levels in the brain of fruit flies. view more (2005-07-11)
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)
Rice researchers gain new insight into nanoscale optics
New research from Rice University has demonstrated an important analogy between electronics and optics that will enable light waves to be coupled efficiently to nanoscale structures and devices. view more (2005-09-15)
Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is stuffing itself with smaller galaxies caught like... view more...

Greenland glaciers dumping ice into Atlantic at faster pace
The amount of ice that Greenland's glaciers dump into the Atlantic Ocean has almost doubled in the last five years because glaciers are moving faster, according to a new Science study. view more (2006-02-17)
Milky Way's fastest pulsar is on its way out of the galaxy, astronomers find
The Milky Way's fastest observed pulsar is speeding out of the galaxy at more than 670 miles a second, propelled largely by a kick it received at its birth 2.5 million years ago. view more (2006-02-16)
'Speed of thought' guides brain's memory consolidation
Scientists at The University of Arizona have added another piece of the puzzle of how the brain processes memory. view more (2007-11-16)
Earth's strongest winds wouldn't even be a breeze on these planets
Earth's inhabitants are used to temperatures that vary, sometimes greatly, between day and night. New measurements for three planets outside our solar system indicate their temperatures remain fairly constant - and blazing hot - from day to night, even though it is likely one side of each planet always faces its sun and the other is in permanent... view more...

Does missing gene point to nocturnal existence for early mammals?
A gene that makes cells in the eye receptive to light is missing in humans, researchers have discovered. view more (2006-10-13)
Cosmic battle creates Milky-Way sized tunnel
A team of astronomers is announcing today that they have discovered a giant Milky Way-sized tunnel filled with high energy particles in a distant galaxy cluster. view more (2006-01-12)
The inside dope
Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon - a process called doping. view more (2007-07-27)
One reason to test premature babies early: Results provide clues to later cognitive development
Now a study from researchers at the Albert Einstein College of Medicine in the Bronx, N.Y., and the University of Ghent in Belgium, finds that early cognitive deficits in infancy such as poorer attention, slower processing speed and poorer recognition memory are important harbingers of later cognitive deficits. view more (2005-11-14)
