Blink, and the brain misses it
We would immediately notice if the outside world suddenly went dark every few seconds. But we rarely become aware of our blinks, even though they cause a similar reduction in the amount of light entering the eye. So why are we not aware of the frequent mini-blackouts caused by blinks? view more (2005-07-26)
U. T. Dallas-led research team produces strong, transparent carbon nanotube sheets
University of Texas at Dallas (UTD) nanotechnologists and an Australian colleague have produced transparent carbon nanotube sheets that are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays. view more (2005-08-19)
Using invisibility to increase visibility
Research into the development of invisibility devices has spurred two physicists' thought on the behaviour of light to overcome the seemingly intractable problem of optical singularities which could soon lead to the manufacturing of a perfect cat's eye. view more (2008-12-01)
South African Large Telescope (SALT) Makes Its Debut
Rutgers, The State University of New Jersey, today joined 10 partners worldwide to release the first full-color astronomical images made by the Southern African Large Telescope (SALT) in South Africa. view more (2005-09-02)
It will be possible to predict earthquakes from space
The scientists of the Department of Physics, Moscow State University, have proposed to predict earthquakes by measuring polarization of the solar light that is reflected from the surface of the Earth. The small and cheap equipment, which the scientists have designed, can be placed on meteorological satellites. Polarization of solar light at... view more... (2001-01-17)
New coating is virtual black hole for reflections
Researchers have created an anti-reflective coating that allows light to travel through it, but lets almost none bounce off its surface. At least 10 times more effective than the coating on sunglasses or computer monitors, the material, which is made of silica nanorods, may be used to channel light into solar cells or allow more photons to surge... view more...

Supermarket lighting enhances nutrient level of fresh spinach
Far from being a food spoiler, the fluorescent lighting in supermarkets actually can boost the nutritional value of fresh spinach, scientists are reporting. view more (2010-03-04)

Keep On Spinning
By controlling the collective spin state of highly mobile electrons in semiconductors, researchers in the Materials Sciences Division (MSD) at the U.S. Department of Energy's Lawrence Berkeley National Laboratory have taken a major step forward in the technology of spintronics. view more (2009-04-02)
Researchers link melanopsin gene to unexplored light detection system within the eye.
Discovery could explain why light keeps us awake and may lead to new treatments for disorders such as jet-lag and SAD. Researchers from Imperial College London, Johns Hopkins University, USA and Brown University, USA have discovered that melanopsin, a recently identified protein, plays a key role in a completely new light detection system in the... view more...

New Evidence on How our Eyes use Light to Manage our Body Clock - University of Surrey Groundbreaking Study Results
A new study published this week shows for the first time that the human eye is sensitive to short wave length visible light and transmits information to the body clock in a way that may make it possible to manipulate waking and sleeping rhythms. This new data, gained from a study carried out at the University of Surrey, might enable this type of... view more... (2001-08-20)
Larvae shun the light
Drosophila larvae avoid light during the foraging stage of their development. Research published in the open access journal BMC Neuroscience shows that both 5-HT (serotonergic) and corazonergic neurons have a role in regulating this behavior. view more (2009-06-23)
New Laser Technique Advances Nanofabrication Process
The ability to create tiny patterns is essential to the fabrication of computer chips and many other current and potential applications of nanotechnology. view more (2009-04-10)
New light shed on marine luminescence
The phenomenon of light emission by living organisms, bioluminescence, is quite common, especially in marine species. view more (2009-02-23)
Major breakthrough in the mechanism of myelin formation
The group of Dr. Michel Cayouette, researcher at Institut de recherches cliniques de Montréal (IRCM), and Dr. Jonah Chan, collaborator at the University of Southern California, will publish in the next issue of the prestigious scientific journal Science, the results of their study that could have a major impact on the treatment of diseases... view more...

Bright lights, not-so-big pupils
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain. The report appears online this week in Nature. view more (2009-01-05)
Researchers discover way to make cells in the eye sensitive to light
Researchers have discovered a way to make light sensitive cells in the eye by switching on a single gene. view more (2005-01-24)
Light powered platinum more targeted & 80 times more powerful than similar cancer treatments
Researchers from the Universities of Warwick, Edinburgh, Dundee and the Czech Republic's Institute of Biophysics have discovered a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use "light activation" to kill cancer cells in much more targeted way... view more...

Guiding light - CMD19/CMMP with The Physics Congress 2002
A new type of optical material has been developed by physicists that could replace the electronics used to route the light signals through optical fibre telecommunications networks. It could even provide the basis for future `optical computers` working on light pulses instead of electric signals. At the Condensed Matter conference on Monday 8... view more... (2002-03-26)
Novel nano-etched cavity makes leds 7 times brighter
Researchers at the National Institute of Standards and Technology (NIST) have made semiconductor light-emitting diodes (LEDs) more than seven times brighter by etching nanoscale grooves in a surrounding cavity to guide scattered light in one direction. view more (2006-07-24)
