Go Speed Racer! Revving up the world's fastest nanomotors
In a "major step" toward a practical energy source for powering tomorrow's nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal. view more (2008-05-01)
Maybe it's raining less than we thought
It's conventional wisdom in atmospheric science circles: large raindrops fall faster than smaller drops, because they're bigger and heavier. view more (2009-06-11)
With double frequency to deeper blue
Light transports data at high speed over fibre-optic networks. Light measures and creates images of large and small objects in scanners and microscopes. Light writes information onto all sorts of recording media and surfaces. The best-quality light is produced by lasers, which have meanwhile become an indispensable tool - not only in medicine and... view more... (2003-07-01)
Found — the apple gene for red
CSIRO researchers have located the gene that controls the colour of apples - a discovery that may lead to bright new apple varieties. view more (2006-12-04)
Tycho's Remnant Provides Shocking Evidence for Cosmic Rays
Astronomers have found compelling evidence that a supernova shock wave has produced a large amount of cosmic rays, particles of mysterious origin that constantly bombard the Earth. view more (2005-09-23)
Bright light therapy eases bipolar depression for some
Bright light therapy can ease bipolar depression in some patients, according to a study published in the journal Bipolar Disorders. view more (2008-01-04)
Optical wireless and broadband over power lines: High speed, secure Wi-Fi alternative
Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF. view more (2006-01-12)
Clearest video of lightning-generated 'sprites' high above thunderstorms captured
Researchers at Duke University's Pratt School of Engineering have captured the best images ever produced of "sprites" - mysterious flashes of light resembling giant undulating jellyfish that can occur above strong thunderstorms - using a high-speed camera that recorded thousands of video frames a second. view more (2006-02-16)
European light research opens door for optical storage and computing
The goal of replacing electronics with optics for processing data in computers is coming closer through cutting edge European research into the mysterious properties of "fast and slow" light. view more (2008-04-25)
Alzheimer's disease progresses more rapidly in highly educated people
High levels of education may help ward off Alzheimer's disease, but they also speed up its progression once developed, reveals research in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-02-16)
High Speed Wireless Data Transfer from VTT, Technical Research Centre of Finland
VTT (Technical Research Centre of Finland) has developed a fast and flexible radio modem, enabling wireless indoor network. The performance of the modem is approximately 20-200 times better compared to similar commercial (WLAN, Bluetooth) technologies. If compared to GSM and UMTS technologies, the new modem is 5000 times faster than the former and... view more... (2002-09-02)
MIT 'optics on a chip' may revolutionize telecom, computing
In work that could lead to completely new devices, systems and applications in computing and telecommunications, MIT researchers are bringing the long-sought goal of "optics on a chip" one step closer to market. view more (2007-02-06)
100 Photographs in the Blink of an Eye
Scientists from the Universities of Sheffield and Southampton in collaboration with the UK Astronomy Technology Centre at the Royal Observatory, Edinburgh have just opened a new window on the Universe by commissioning ULTRACAM - an ultra-fast camera which can take up to 1000 pictures a second in three different colours simultaneously. The camera,... view more... (2002-07-24)
Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser
An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. view more (2009-06-01)
Menopause transition may cause trouble learning
The largest study of its kind to date shows that women may not be able to learn as well shortly before menopause compared to other stages in life. view more (2009-05-26)
World's fastest camera relies on an entirely new type of imaging
Ultrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells, neural activity, laser surgery and elements of blood analysis. view more (2009-04-30)
NASA's Swift Sees Double Supernova in Galaxy
In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time. view more (2007-06-27)
Squid 'sight': Not just through eyes
It's hard to miss the huge eye of a squid. But now it appears that certain squids can detect light through an organ other than their eyes as well. view more (2009-06-02)
NASA: Major Step Toward Knowing Origin of Cosmic Rays
Recent observations from NASA and Japanese X-ray observatories have helped clarify one of the long-standing mysteries in astronomy -- the origin of cosmic rays. view more (2007-10-10)
Prize-winner emerges from the shadows
How can you measure the brightness of light? A book which examines the answers to this seemingly simple question has just won the 2003 Paul Bunge Award, the world's largest prize for research in the history of scientific instruments. The book, published in 2001 by Institute of Physics Publishing, is "A History of Light and Colour Measurement:... view more... (2003-11-04)
