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)

A team of researchers at Princeton University's Materials Research Science and Engineering Center has observed electrons moving through a crystal of bismuth metal behaving like light.   view more (2008-07-28)

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)

Hubble finds large sample of very distant galaxies
New Hubble Space Telescope observations of six spectacular galaxy clusters acting as gravitational lenses have given significant insights into the early stages of the Universe. Scientists have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at... view more (2008-07-25)

Polarizing filter allows astronomers to see disks surrounding black holes
For the first time, a team of international researchers has found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be.   view more (2008-07-24)

Does too much sun cause melanoma?
We are continuously bombarded with messages about the dangers of too much sun and the increased risk of melanoma (the less common and deadliest form of skin cancer), but are these dangers real, or is staying out of the sun causing us more harm than good?   view more (2008-07-23)

New Approach Sheds Light on Ways Circadian Disruption Affects Human Health
Growing evidence indicates that exposure to irregular patterns of light and darkness can cause the human circadian system to fall out of synchrony with the 24-hour solar day, negatively affecting human health - but scientists have been unable to effectively study the relationship between circadian... view more (2008-07-17)

Researchers generate hydrogen without the carbon footprint
A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers.   view more (2008-07-16)

Freeing light shines promise on energy-efficient lighting
The latest bright idea in energy-efficient lighting for homes and offices uses big science in nano-small packages to dim the future Edison's light bulb.   view more (2008-07-16)

A Colorful Approach to Solar Energy
Revisiting a once-abandoned technique, engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator.   view more (2008-07-11)

Nano-sized Electronic Circuit Promises Bright View of Early Universe
A newly developed nano-sized electronic device is an important step toward helping astronomers see invisible light dating from the creation of the universe. This invisible light makes up 98% of the light emitted since the "big bang," and may provide insights into the earliest stages of... view more (2008-07-11)

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)

A bright future for plastics -- robot 'skin,' flexible laptops and electric posters
With market analysts predicting a ten fold increase in the value of the organic light emitting display industry, from £1.5 billion to £15.5 billion, by 2014, it is no wonder that scientists and governments alike are keen to advance research into "plastic electronics".   view more (2008-07-01)
