Empa scientists synthesize graphene-like material
Two-dimensional carbon layers, so-called graphenes, are regarded as a possible substitute for silicon in the semiconductor industry. view more (2009-11-24)
New study confirms exotic electric properties of graphene
First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. view more (2009-11-18)
Swift XMM-Newton Satellites Tune Into a Middleweight Black Hole
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. view more (2009-11-11)
Skunk's Strategy Not Just Black and White
Predators with experience of skunks avoid them both because of their black-and-white coloration and their distinctive body shape, according to UC Davis wildlife researcher Jennifer Hunter. view more (2009-11-11)
New finding suggests prostate biopsy is not always necessary
Researchers at Wake Forest University School of Medicine and the University of Wisconsin-Madison have discovered that some elevated prostate-specific antigen (PSA) levels in men may be caused by a hormone normally occurring in the body, and are not necessarily a predictor of the need for a prostate biopsy. view more (2009-11-09)
Use of cannabinoids (marijuana) could help post-traumatic stress disorder patients
Use of cannabinoids (marijuana) could assist in the treatment of post-traumatic stress disorder patients. This is exposed in a new study carried out at the Learning and Memory Lab in the University of Haifa's Department of Psychology. view more (2009-11-05)
Pandemic flu vaccine campaigns may be undermined by coincidental medical events
The effectiveness of pandemic flu vaccination campaigns - like that now underway for H1N1 - could be undermined by the public incorrectly associating coincidental and unrelated health events with the vaccines. view more (2009-11-02)
Fermi telescope caps its first year with a glimpse of space-time
During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. view more (2009-10-29)
Latest analysis confirms suboptimal vitamin D levels in millions of US children
Millions of children in the United States between the ages of 1 and 11 may suffer from suboptimal levels of vitamin D, according to a large nationally representative study published in the November issue of Pediatrics, accompanied by an editorial. view more (2009-10-26)
Where surgery was the standard, casting may be the future
When parents are told their babies' scoliosis needs treatment, they often try bracing first. If that fails, they need surgery to place metal rods in their backs with spinal fusion later on. These children face the risk of complications from the surgery and their backs and chests may be stiff for life. view more (2009-10-01)
Body's immune system response to dental plaque varies by gender and race
Will neglecting to brush your teeth damage more than just your smile? Can failing to attack dental plaque increase your risk of heart damage? view more (2009-09-25)
New vista of Milky Way center unveiled
A dramatic new vista of the center of the Milky Way galaxy from NASA's Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center. view more (2009-09-23)
Invading black holes explain cosmic flashes
Black holes are invading stars, providing a radical explanation to bright flashes in the universe that are one of the biggest mysteries in astronomy today. view more (2009-09-21)
Radiologists and engineers develop a modified catheter to reduce contrast material injuries
Though rare, IV contrast material administration can sometimes result in patient injury. However researchers have developed a modified catheter that may prevent such events from occurring. view more (2009-09-21)
Solar Cycle Driven by More than Sunspots; Sun Also Bombards Earth with High-Speed Streams of Wind
Challenging conventional wisdom, new research finds that the number of sunspots provides an incomplete measure of changes in the Sun's impact on Earth over the course of the 11-year solar cycle. view more (2009-09-18)
Swift Makes Best-ever Ultraviolet Portrait of Andromeda Galaxy
In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. view more (2009-09-17)
Sophisticated telescope camera debuts with peek at nest of black holes
Less than two months after they inaugurated the world's largest telescope, University of Florida astronomers have used one of the world's most advanced telescopic instruments to gather images of the heavens. view more (2009-09-16)
COES professor's 'metamaterials' research lands cover of international journal
Dr. Dentcho Genov, an assistant professor of physics and electrical engineering at Louisiana Tech University and a Louisiana Optical Network Initiative (LONI) Institute fellow, is featured on the cover of the most recent issue of Nature Physics, one of the most respected and prestigious physics journals in the world. view more (2009-09-11)
University of Nevada, Reno researcher uses 100,000 degree heat to study plasma
Using one of the greatest sources of radiation energy created by man, University of Nevada, Reno researcher and faculty member Roberto Mancini is studying ultra-high temperature and non-equilibrium plasmas to mimic what happens to matter in accretion disks around black holes. view more (2009-09-03)
Precise Radio-Telescope Measurements Advance Frontier Gravitational Physics
Scientists using a continent-wide array of radio telescopes have made an extremely precise measurement of the curvature of space caused by the Sun's gravity, and their technique promises a major contribution to a frontier area of basic physics. view more (2009-09-02)
