Baby boomers' boon? LED light and green tea cream to smooth facial wrinkles
Scientists in Germany are reporting a major improvement in their potential new treatment for facial wrinkles that could emerge as an alternative to Botox and cosmetic surgery. view more (2009-09-10)
MU Researchers Make Discovery in Molecular Mechanics of Phototropism
In a paper published in the Journal of Biological Chemistry, scientists at the University of Missouri-Columbia reported molecular-level discoveries about the mechanisms of phototropism, the directional growth of plants toward or away from light. view more (2007-07-09)
Research Will Push Forward Fight Against Leukaemia
A project which aims to make laboratory-grown leukaemia cells change form and then be used to prime a patient's own immune system to kill off malignant cells has begun in Edinburgh. If successful, the study could give clinicians a way of destroying residual leukaemic cells which are undetectable by microscope. The findings could be helpful in the... view more... (2002-10-25)
New view of the eye
Full colour images of the back of the eye are now better than ever thanks to research published today in the Institute of Physics journal Physiological Measurement. The new technique developed by Dr Ayyakkannu Manivannan and colleagues at the University of Aberdeen uses low-power coloured lasers to give a full colour picture that ophthalmologists... view more...

The giant protein titin helps build muscles
Under the microscope, muscle looks like millions of tiny pistons, stacked end-to-end into long rows. These structures, called sarcomeres, permit the contraction and relaxation of muscle that allow our bodies to move. view more (2006-01-12)
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)
Research could lead to new treatments for blindness
Scientists have discovered how to make cells sensitive to light in what may lead to a new approach to treating certain forms of blindness. view more (2005-01-24)
The Bees' Kamasutra
Female leaf-cutter bees are choosy about their sexual partners: they only fall for males who give off the appropriate smell. Zoologists at the University of Bonn have discovered that the male bees actually have to rub their scent under their partners' noses. Glands in their front legs serve as "scent sprays". There is not much room for... view more... (2002-03-12)
Tiny lasers get a notch up
Tiny disk-shaped lasers as small as a speck of dust could one day beam information through optical computers. Unfortunately, a perfect disk will spray light out, not as a beam, but in all directions. view more (2009-01-23)
Plastic solar cell efficiency breaks record at WFU nanotechnology center
The global search for a sustainable energy supply is making significant strides at Wake Forest University as researchers at the university's Center for Nanotechnology and Molecular Materials have announced that they have pushed the efficiency of plastic solar cells to more than 6 percent. view more (2007-04-20)
Sunburn alert: UVB does more damage to DNA than UVA
As bombs burst in air this July 4, chances are that sunburn will be the red glare that most folks see - and feel. But unfortunately, even when there is no burn, the effects of the sun's ultraviolet (UV) rays can have deadly consequences. view more (2008-07-01)
New fruit fly protein illuminates circadian response to light
Researchers at the University of Pennsylvania School of Medicine have identified a new protein required for the circadian response to light in fruit flies. view more (2006-06-30)
Pushing light beyond its known limits
Scientists at the University of Adelaide have made a breakthrough that could change the world's thinking on what light is capable of. view more (2009-11-13)
NIST method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes. view more (2006-02-17)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)
Optical vortex could look directly at extrasolar planets
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. view more (2005-12-01)
UCSB researchers discover the dawn of animal vision
By peering deep into evolutionary history, scientists at the University of California, Santa Barbara have discovered the origins of photosensitivity in animals. view more (2007-10-17)
Yale researchers make cell biology quantitative
Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively. view more (2005-10-20)
Warp drive a no go
Sci-fi experts know that many seemingly impossible technologies materialise years later, but unfortunately this may not to be the case for warp-drive - travelling through space faster than the speed of light. The favourite science fiction theory of space contracting in front of spacecraft, and expanding behind it to form warp-drive is under threat... view more... (2002-03-05)
A new window into the deformation of nanoscale materials
Materials on the nanoscale don't always have the same properties they would in bulk; for one thing, nanomaterials are often a lot harder. Unlike most bulk materials, a crystal that is small enough can be perfect, free of defects, capable of achieving strength near its ideal theoretical limit. view more (2006-08-14)
