Study compares treatments for chronic plaque psoriasis
UV-A therapy was found to be more effective than narrowband UV-B therapy in treating patients with chronic plaque psoriasis.   view more (2006-07-18)

Nuclear explosion on a dead star - astronomers probe aftermath
A team of astronomers from the UK and Germany have found that a nuclear explosion on the surface of a star 5,000 light years from Earth resulted in a blast wave moving at over 1,700 km per second (one thousand miles per second or almost four million miles per hour!).   view more (2006-07-20)

A sub-femtosecond stop watch for 'photon finish' races
Using a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably... view more (2008-03-14)

Most Katrina evacuees in Houston plan to stay here
More than two-thirds of the Hurricane Katrina evacuees who fled to Houston for shelter a year ago said they plan to remain here, according to a recent survey by researchers at Rice University.   view more (2006-09-11)

New insight in star formation
Early stages of star formation are now better understood, following an extensive millimeter-wave study of protostars, which are young stellar objects still deeply embedded in their parent molecular cloud. Thanks to their unprecedented high-resolution maps of the circumstellar environment of many... view more (2001-01-16)

AP2000 Millennium Conference on Antennas & Propagation
Antennas and radio-wave propagation involve key technologies for space communications, navigation and remote sensing, for all terrestrial wireless transmission systems, for radar, and for a number of other applications ranging from mine detection to biological wave interactions and medical... view more (2000-03-24)

First few seconds of earthquake rupture provides data for distant shake warnings
A University of California, Berkeley, seismologist has discovered a way to provide seconds to tens of seconds of advance warning about impending ground shaking from an earthquake.   view more (2005-11-10)

Illegal destruction of coral reefs worsened impact of tsunami
The illegal mining of corals off the southwest coast of Sri Lanka permitted far more onshore destruction from the 26 December 2004 tsunami than occurred in nearby areas whose coral reefs were intact.   view more (2005-08-16)

First demonstration of new laser-driven accelerator technology
A team of UK scientists has used, for the first time, an extremely short-pulse laser to accelerate high-energy electrons over an incredibly short distance. Current accelerators can be hundreds of metres long, this is just a millimetre long.   view more (2004-09-28)

Supernova radiation simulated in Virtual Reality
To astrophysicists, the energy-charged x-ray radiation on the fringes of a supernova explosion has long been enigmatic. It hasn't been possible to explain how the electrons are able to accelerate to nearly the speed of light. Now scientists in England and in Linköping, Sweden, have hit upon a... view more (2001-12-20)

New Hypothesis Of The Tunguska Explosion
The event which occurred almost a hundred years ago in Podkamennaya Tunguska has drawn scientists` attention again. What actually exploded at that time in the remote taiga, the power of explosion being equal to the 50-megaton H-bomb? The hypothesis that it was a meteorite or any other... view more (2002-08-23)

UO plays key role in LIGO's new view of a cosmic event
An international team of physicists, including University of Oregon scientists, has concluded that last February's intense burst of gamma rays possibly coming from the Andromeda Galaxy lacked a gravitational wave. That absence, they say, rules out an initial interpretation that the burst came from... view more (2008-01-04)

Photocell Provides Both Heat And Electricity
In 1969, scientists at the Ioffe Physico-Technical Institute, St. Petersburg made heterostructured photoelectric cells based on the elements of the third and the fifth group of the periodic table (for example, gallium arsenide). Now the photocells can find application not only in space, but also on... view more (2001-11-27)

Stretchable silicon could be next wave in electronics
Researchers at the University of Illinois at Urbana-Champaign have developed a fully stretchable form of single-crystal silicon with micron-sized, wave-like geometries that can be used to build high-performance electronic devices on rubber substrates.   view more (2005-12-16)

Superstrings could add gravitational cacophony to universe's chorus
Albert Einstein theorized long ago that moving matter would warp the fabric of four-dimensional space-time, sending out ripples of gravity called gravitational waves. No one has observed such a phenomenon so far, but University of Washington researchers believe it is possible to detect such waves... view more (2007-01-09)

Study, meta-analysis examine factors associated with death from heatstroke
Individuals who live in a nursing home or take medication to lower blood pressure appear more likely to die during or following hospitalization for heatstroke.   view more (2007-08-14)

Huge tsunami spurred progress, revealed needs
The catastrophic tsunami that struck Indonesia and East Asia almost a year ago has done much to heighten the interest, research programs and preparations in the United States for events of this type, but experts say there are areas that need more attention and challenges yet to be met.   view more (2005-12-05)

Researchers learn from analyses of rare tsunami earthquake
Analyses of a classic, slow-rupturing tsunami earthquake whose massive waves devastated the coast of Java, Indonesia, this past summer are providing insight to seismologists and engineers, who want to better understand these rare events, recommend strategies to improve safety and perhaps provide... view more (2006-12-07)

Silicon photonic crystals key to optical cloaking, researchers say
In computer simulations, the researchers have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking.   view more (2008-06-26)

Nutrient recycling - the ideal way to avoid nutrient limitation in a grazer community
The rocky shore of Lake Erken, Sweden, is inhabited by the sessile psychomyiid caddisfly Tinodes waeneri (L.). The larva lives in a gallery, consisting of a spun silken web plus other organic and inorganic material associated with the web (Danecker 1961, Becker 1993, Hasselrot 1993a). The... view more (2000-01-17)

For The First Time, Patterns Of Excitation Waves Found In Brain's Visual Processing Center
Neuroscientists have long believed that vision is processed in the brain along circuits made up of neurons, similar to the way telephone signals are transferred through separate wires from one station to another.   view more (2007-08-01)

Shoulder tapping -- U of M study finds young men more willing to purchase alcohol for underage youth
Nearly 20 percent of young males are willing to purchase alcohol for underage youth when approached outside of an alcohol establishment, according to researchers at the University of Minnesota School of Public Health.   view more (2007-06-26)

New discovery at Jupiter could help protect Earth-orbit satellites
Radio waves accelerate electrons within Jupiter's magnetic field in the same way as they do on Earth, according to new research published in Nature Physics this week. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting... view more (2008-03-10)

Laser tweezers sort atoms
Physicists of the University of Bonn have taken one more important hurdle on the path to what is known as a quantum computer: by using 'laser tweezers' they have succeeded in sorting up to seven atoms and lining them up.   view more (2006-07-13)

Catching waves: Measuring self-assembly in action
By making careful observations of the growth of a layer of molecules as they gradually cover the surface of a small silicon rectangle, researchers from the National Institute of Standards and Technology (NIST) and North Carolina State University (NCSU) have gained basic insights into how... view more (2007-06-25)
