Everybody loves a race to the wire, even when the result is a tie. The great irony is the ultraprecise clocks that could result from this competition could probably break any tie.
BOULDER, Colo. -- Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first "universal" programmable quantum information
processor able to run any program allowed by quantum mechanics -- the rules governing the submicroscopic world -- using two quantum bits (qubits) of information.
Scientists at the University of Adelaide have made a breakthrough that could change the world's thinking on what light is ca
According to a recent report by the National Research Council of the National Academy of Sciences, the United States, once the world leader in the discovery and growth of crystalline materials, is
GAINESVILLE, Fla. -- Most biopsies following mammograms reveal benign abnormalities, not cancer.
Using Einstein's theory of special relativity to speedup computer simulations, scientists have designed laser-plasma accelerators with energies of 10 billion electron volts (GeV) and beyond.
A new generation of high-energy (>kJ) petawatt (HEPW) lasers is being constructed worldwide to study high intensity laser matter interactions, including fast ignition.
LOS ALAMOS, New Mexico, Oct 28, 2009 -- For years scientists have struggled with the difficult physics of inertial confinement fusion.
A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. The room-temperature technique allows researchers to identify previously unseen molecules in living organisms and offers broad applications in biomedical imaging and research.
San Diego, CA -- While operating room fires can occur in a variety of clinical settings, it is the use of lasers and electrosurgical devices that are most likely to cause them. Those are the findings in new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA.
(Boston) - Researchers from Boston University School of Medicine (BUSM) have concluded that the 940nm wavelength laser is superior for treating facial spider veins (telangiectasias) as compared to the 532nm wavelength laser. The findings, which appear in the recent issue of Lasers in Surgery and Medicine, are the first time these lasers were tested against each other for superiority.
The National Physical Laboratory (NPL) has helped to establish that femtosecond comb lasers can provide accurate measurement of absolute distance in formation flying space missions.
NPL, along with collaborators, produced technical reports for the European Space Agency. The conclusions demonstrated that the lasers were a suitable method for measurement in such missions.
Carbon nanotubes, photovoltaics and the "hydrogen economy" -- not exactly household concepts yet. But they are technologies at the forefront of the growing worldwide demand for "green" energy and manufacturing. And lasers are critical to this global revolution.
In the air, it is a serious pollutant. In the body, it plays a role in heart rate, blood flow, nerve signals and immune function.
Nitric oxide, a gas well known to scientists for its myriad functions, has proven challenging to measure accurately outside the laboratory.
WASHINGTON, Sept. 18 -- Tomorrow's lasers may come with a bit of bling, thanks to a new technology that uses man-made diamonds to enhance the power and capabilities of lasers. Researchers in Australia have now demonstrated the first laser built with diamonds that has comparable efficiency to lasers built with other materials.
