Flexi display technology is now
Rigid television screens, bulky laptops and still image posters are to be a thing of the past as new research, published today, Thursday, 2 October, in the New Journal of Physics, heralds the beginning of a technological revolution for screen displays.    view more (2008-10-02)

Are we trading energy conservation for toxic air emissions?
A team of Yale scientists has found that certain countries and some U.S. states stand to benefit from the use of compact fluorescent lighting more than others in the fight against global warming. Some places may even produce more mercury emissions by switching from incandescent light bulbs to... view more (2008-10-01)

Argonne scientists peer into heart of compound that may detect chemical, biological weapons
A light-transmitting compound that could one day be used in high-efficiency fiber optics and in sensors to detect biological and chemical weapons at long distance almost went undiscovered by scientists because its structure was too difficult to examine.   view more (2008-09-29)

Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain.   view more (2008-09-29)

NASA's Swift Catches Farthest Ever Gamma-Ray Burst
NASA's Swift satellite has found the most distant gamma-ray burst ever detected. The blast, designated GRB 080913, arose from an exploding star 12.8 billion light-years away.   view more (2008-09-23)

Improving our ability to peek inside molecules
It's not easy to see a single molecule inside a living cell. Nevertheless, researchers at Lawrence Livermore National Laboratory are helping to develop a new technique that will enable them to create detailed high-resolution images, giving scientists an unprecedented look at the atomic structure of... view more (2008-09-17)

'Naked-eye' gamma-ray burst was aimed squarely at Earth
Data from satellites and observatories around the globe show a jet from a powerful stellar explosion witnessed March 19 was aimed almost directly at Earth.   view more (2008-09-12)

The Double Firing Burst
Astronomers from around the world combined data from ground- and space-based telescopes to paint a detailed portrait of the brightest explosion ever seen. The observations reveal that the jets of the gamma-ray burst called GRB 080319B were aimed almost directly at the Earth.   view more (2008-09-11)

Brightest stellar explosion heralds new type of long-distance astronomy
A flash of light that blinded even small telescopes six months ago was the brightest astronomical explosion ever observed - visible to the naked eye despite originating halfway across the universe.   view more (2008-09-11)

New virtual telescope zooms in on Milky Way's super-massive black hole
An international team, led by astronomers at the MIT Haystack Observatory, has obtained the closest views ever of what is believed to be a super-massive black hole at the center of the Milky Way galaxy.   view more (2008-09-04)

K-State professor's research suggests that cigarettes' power may not be in nicotine itself
There may be a very good reason why coffee and cigarettes often seem to go hand in hand.   view more (2008-09-04)

Invisibility undone
Harry Potter beware! A team of Chinese scientists has developed a way to unmask your invisibility cloak. According to a new paper in the latest issue of Optics Express, the Optical Society's (OSA) open-access journal, certain materials underneath an invisibility cloak would allow invisible objects... view more (2008-09-03)

Fast quantum computer building block created
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.   view more (2008-08-21)

University of Pennsylvania Scientists Move Optical Computing Closer to Reality
Scientists at the University of Pennsylvania have theorized a way to increase the speed of pulses of light that bound across chains of tiny metal particles to well past the speed of light by altering the particle shape.   view more (2008-08-20)

Light Receptors in Eye Play Key Role in Setting Biological Clock, Study Shows
Biologists at the University of Virginia have discovered a switching mechanism in the eye that plays a key role in regulating the sleep/wake cycles in mammals.   view more (2008-08-18)

'Erasing' drug-associated memories may stop drug addiction relapses
'Erasing' drug-associated memories may prevent recovering drug abusers from relapsing, researchers at the University of Cambridge have discovered.    view more (2008-08-13)

Hubble unveils colourful star birth region on 100 000th orbit milestone
In commemoration of the NASA/ESA Hubble Space Telescope completing its 100 000th orbit around the Earth in its 18th year of exploration and discovery, scientists have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal.   view more (2008-08-11)

New metamaterials that bend light backwards bring invisibility cloaks 1 step closer
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered... view more (2008-08-11)

Toxic drugs, toxic system: Sociologist predicts drug disasters
Americans are likely to be exposed to unacceptable side effects of FDA-approved drugs such as Vioxx in the future because of fatal flaws in the way new drugs are tested and marketed, according to research to be presented today at the annual meeting of the American Sociological Association (ASA).   view more (2008-08-04)
