New 'nano-positioners' may have atomic-scale precision
Engineers have created a tiny motorized positioning device that has twice the dexterity of similar devices being developed for applications that include biological sensors and more compact, powerful computer hard drives. view more (2008-08-21)
'Tunable' network features coordinated frequency combs
A super stable fiber-optic network that can be tuned across a range of visible and near-infrared frequencies while synchronizing the oscillations of light waves from different sources has been demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-05-14)
Creating the astro-comb to locate Earth-like planets
Thanks to the ability of astronomers to detect the presence of extrasolar planets orbiting distant stars, scientists today are able to examine hundreds of solar systems. view more (2009-05-08)
Purdue 'milestone' a step toward advanced sensors, communications
Engineers at Purdue University have shown how to finely control the spectral properties of ultrafast light pulses, a step toward creating advanced sensors, more powerful communications technologies and more precise laboratory instruments. view more (2007-08-02)
Record-setting laser may aid searches for Earthlike planets
Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) have demonstrated an ultrafast laser that offers a record combination of high speed, short pulses and high average power. view more (2008-05-08)
Scientists using laser light to detect potential diseases via breath samples, says new study
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer. view more (2008-02-19)
Laser light may be able to detect diseases on the breath
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person's breath with laser light they can detect molecules in the breath that may be markers for diseases like asthma or cancer. view more (2008-02-19)
Heads-up study of hair dynamics may lead to better hair-care products
rom frizzy perms to over-bleached waves, "bad hair days" could soon become a less frequent occurrence. Chemists report the first detailed microscopic analysis of what happens to individual hair fibers when they interact with each other, an advance in knowledge key to the development of improved shampoos, conditioners, and other products... view more...

Optical 'frequency comb' can detect the breath of disease
Exhale on a cold winter day and you will see the water vapor coming out of your mouth. Light up your breath with a Nobel-Prize-related tool, and you could potentially detect trace amounts of over 1,000 compounds, some of which provide early warning signs of disease. view more (2008-02-20)
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)
Brown-led study rearranges some branches on animal tree of life
A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species. view more (2008-03-06)
Early family ties: No sponge in the human family tree
Since the days of Charles Darwin, researchers are interested in reconstructing the "Tree of Life", and in understanding the development of animal and plant species during their evolutionary history. view more (2009-04-03)
Many patients who resume driving after head injury may not be fit to drive
Many patients who return to driving after traumatic brain injury report problems which can significantly affect their ability to drive, finds a study in Journal of Neurology Neurosurgery and Psychiatry. During a two and a half year period, 563 adults with traumatic brain injury were referred to one of 10 rehabilitation units in England. Patients... view more... (2001-05-30)
Tongue Drive Technology
Researchers have developed an experimental tongue-based system that may allow individuals with debilitating disabilities to control wheelchairs, computers and other devices with relative ease and no sophistication. view more (2008-07-22)
Atomic fountain clocks are becoming still more stable
They are at present the most accurate clocks in the world: Caesium fountain clocks furnish the second accurate to 15 places after the decimal point. Until they reach this accuracy, caesium fountain clocks, however, need a certain measurement time. view more (2009-03-18)
The puzzle of seat belts explained
Narrow escapes in the car may explain why seat belts save fewer lives than they should, according to Chartered Psychologist Dr Tony Reinhardt-Rutland of the University of Ulster. view more (1999-03-26)
New connecting system for water pipes
Laying water mains has always been a time-consuming job. Each section must be laid, joints welded, the interior checked for heat damage, and any damage repaired. Then the whole thing has to be encased in concrete if the ground is uneven. Now EUREKA project DRIVE-LOCK is about to make the process quicker and cheaper. The French and Swiss partners... view more... (2003-04-24)
'Frequency comb' spectroscopy proves to be powerful chemical analysis tool
Physicists at JILA have designed and demonstrated a highly sensitive new tool for real-time analysis of the quantity, structure and dynamics of a variety of atoms and molecules simultaneously, even in minuscule gas samples. view more (2006-03-17)
Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more stable methods are needed. view more (2007-03-05)
Tackling Drunk-driving
There are no in-car methods of detecting that a driver is too drunk to drive - until now. A team at Bristol University, led by physiologist Dr Dilwyn Marple-Horvat, has found a new way of detecting whether a driver has drunk too much to be fit to be at the wheel. To assess a driver`s fitness to drive, a new device has been created that measures... view more... (2002-03-07)
