Experiment generates THz radiation 20,000 times brighter than anyone else; breakthrough lights way for application development
An experiment conducted with Jefferson Lab’s Free-Electron Laser has shown how to make a highly useful form of light — called terahertz radiation — 20,000 times brigh
A new study suggests that brief exposures to pure oxygen not only help chronic and other hard-to-heal wounds heal completely, such exposures also help wounds heal faster.
Ohio State University surgical scientists used topical oxygen therapy to treat 30 patients with a total of 56 wounds. The therapy required placing a bag containing pure oxygen over the wound for 90 minutes a day. More than two-thirds of the difficult wounds healed with the oxygen treatment alone.
Wounds in this cl
A study led by a Duke University scientist suggests that the current emphasis on controlling upstream nitrogen pollution fails to adequately address the impacts on water quality of another potential contaminant, phosphorus. Thus, according to the scientists, current strategies used by environmental managers to control excessive nutrients in coastal wetlands may not achieve their intended goals.
The finding was published in a report in the Friday, Jan. 24, 2003, issue of the journal Science b
Researchers can now pinpoint direction of elusive subatomic particles key to understanding black holes, other cosmic events
A unique telescope buried in Antarctic ice promises unparalleled insight into such extraordinary phenomena as colliding black holes, gamma-ray bursts, the violent cores of distant galaxies and the wreckage of exploded stars.
An international team of physicists and astronomers, which includes UC Irvine researchers, report that the AMANDA telescope is cap
A new brain imaging method pioneered by a German research group from several institutions can now produce images that localize the areas of the brain involved when test subjects perform physical activities, and can show how portions of the brain interact with each other. The technique, dubbed synchronization tomography, involves mapping the fluctuating magnetic fields produced by tiny electrical currents in the brain, and determining which brain regions are synchronized with an activity – such as a t
Salmonella, E. coli, shigellosis, hepatitis A, and Norwalk — these food-borne diseases can produce symptoms that run from the mild to life-threatening. The young and old are particularly vulnerable and while consumption of beef and poultry have been the most common sources of such infections, fresh fruits and vegetables are being increasingly implicated in such outbreaks. So much so, that plant disease scientists are now taking a closer look at this issue.
“Historically, human pathogens l
