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)
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)
UV light improving chances of fighting cancer
Scientists at Newcastle University have developed a cancer fighting technology which uses UV light to activate antibodies which very specifically attack tumours. view more (2007-10-30)
Study sheds new light on link between birth weight, obesity, and childhood growth
Boys who are light at birth, but then grow rapidly during childhood, are more likely to be obese as adults, is just one of the findings from a large study in this week's BMJ. These potentially complex interrelationships may hold the key to effective preventive strategies. Tessa Parsons and colleagues used data collected from all children born in... view more...

Light sensor breakthrough could enhance digital cameras
New research by a team of University of Toronto scientists could lead to substantial advancements in the performance of a variety of electronic devices including digital cameras. view more (2009-06-19)
People who smoke light cigarettes less likely to quit
People who smoke low-tar and low-nicotine, or "light" cigarettes thinking they will reduce their health risks may actually be less likely to kick the habit. view more (2006-06-30)
Physics breakthrough much ado about 'nothing'
How do scientists store nothing? It may sound like the beginning of a bad joke, but the answer is causing a stir in the realm of quantum physics after two research teams, including one from the University of Calgary, have independently proven it's possible to store a special kind of vacuum in a puff of gas and then retrieve it a split second later. view more (2008-03-06)
Fireflies and jellyfish help illuminate quest for cause of infertility
Genes taken from fireflies and jellyfish are literally shedding light on possible causes of infertility and autoimmune diseases in humans. view more (2009-03-27)
Scientists step closer to realising invisible technology
A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. view more (2007-05-04)
Non-invasive MRI technique distinguishes between Alzheimer's and frontotemporal dementia
A non-invasive magnetic resonance imaging (MRI) technique called arterial spin labeling is just as accurate as invasive scanning techniques in distinguishing Alzheimer's disease from frontotemporal dementia (FTD) in the brains of elderly people, according to a new study at the San Francisco VA Medical Center (SFVAMC). view more (2005-06-20)
Accretion Discs Show Their True Colours
Quasars are the brilliant cores of remote galaxies, at the hearts of which lie supermassive black holes that can generate enough power to outshine the Sun a trillion times. view more (2008-07-25)
Secondhand smoke proves to be no 'joke' on oral health
A study published in this month's issue of the Journal of Periodontology found that subjects with periodontitis who were exposed to secondhand smoke were more likely to develop bone loss, the number one cause of tooth loss. view more (2007-04-04)
Cheap and efficient white light LEDs new design described in AIP's Journal of Applied Physics
Roughly 20 percent of the electricity consumed worldwide is used to light homes, businesses, and other private and public spaces. Though this consumption represents a large drain on resources, it also presents a tremendous opportunity for savings. view more (2009-04-08)
Light-sensitive particles change chemistry at the flick of a switch
A light-sensitive, self-assembled monolayer that provides unique control over particle interactions has been developed by scientists at the University of Illinois at Urbana-Champaign. view more (2006-03-27)
Scientists find new role for the swastika
Just a month after a call for a European-wide ban of the swastika, scientists have found that the symbol has new applications in optical communications and could have a role in quantum cryptography. view more (2005-02-23)
Minerals go 'dark' near Earth's core
Minerals crunched by intense pressure near the Earth's core lose much of their ability to conduct infrared light, according to a new study from the Carnegie Institution's Geophysical Laboratory. view more (2006-05-26)
New phenomenon in physics discovered on illumination of metal surfaces
Scientific research at the Centre of the Physics of Materials, a mixed venture of the Higher Council for Scientific Research (CSIC) and the University of the Basque Country (UPV/EHU) in Donostia-San Sebastian, has enabled the discovery of a new physical phenomenon that affects the surfaces of illuminated metals. view more (2007-07-12)
Astronomers discover stars in early galaxies had a need for speed
A team of astronomers has measured the motions of stars in a very distant galaxy for the first time and discovered they are whizzing around at astonishingly high speeds-about one million miles per hour, or twice the speed at which the Sun circles our own Milky Way galaxy. view more (2009-08-07)
A tiny, tunable well of light, and a string theorist's toolbox
Photonics, the science of using photons to carry information, promises to continue improving a wide variety of technologies, from computing to high-speed communication. view more (2009-09-21)
Funnel in the eye: Signal focusing increases photosensitivity
In poor light the eyes of mice react like some digital cameras: they reduce their resolution while at the same time increasing their sensitivity. Specialists in the retina focus the information of several light sensor cells for this purpose. view more (2006-11-03)
