GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky
The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays.   view more (2008-08-27)

Discovery opens door for drugs to fight bird flu, other influenza epidemics
Researchers at Rutgers University and The University of Texas at Austin have reported a discovery that could help scientists develop drugs to fight the much-feared bird flu and other virulent strains of influenza.   view more (2008-08-26)

Seeing through tooth decay
Dental caries afflict at least 90% of the world's population at some time in their lives. Detecting the first signs of this disease, which can be lethal in extreme cases, just got easier thanks to work by researchers in India discussed in the latest issue of the International Journal of Biomedical... view more (2008-08-25)

Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple... view more (2008-08-20)

Pesticide build-up could lead to poor honey bee health
Honey bees industriously bring pollen and nectar to the hive, but along with the bounty comes a wide variety of pesticides, according to Penn State researchers.   view more (2008-08-19)

X-rays use diamonds as a window to the center of the Earth
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks?   view more (2008-08-13)

Study shows clumps and streams of dark matter in inner regions of the Milky Way
Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system.   view more (2008-08-07)

Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor.   view more (2008-08-05)

The quiet explosion
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts.   view more (2008-07-25)

A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory.   view more (2008-07-17)

Possible link found between x-rays and prostate cancer
Researchers at The University of Nottingham have shown an association between certain past diagnostic radiation procedures and an increased risk of young-onset prostate cancer - a rare form of prostate cancer which affects about 10 per cent of all men diagnosed with the disease.   view more (2008-07-16)

Scientists close in on source of X-rays in lightning
University of Florida and Florida Institute of Technology engineering researchers have narrowed the search for the source of X-rays emitted by lightning, a feat that could one day help predict where lightning will strike.   view more (2008-07-16)

Schizophrenia linked to dysfunction in molecular brain pathway activated by marijuana
Alterations in a molecular brain pathway activated by marijuana may contribute to the cognitive symptoms of schizophrenia, according to a report in the July issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2008-07-08)

Statins have unexpected effect on pool of powerful brain cells
Cholesterol-lowering drugs known as statins have a profound effect on an elite group of cells important to brain health as we age, scientists at the University of Rochester Medical Center have found. The new findings shed light on a long-debated potential role for statins in the area of dementia.   view more (2008-07-07)

Argonne's Hard X-ray Nanoprobe provides new capability to study nanoscale materials
The Center for Nanoscale Materials' (CNM) newly operational Hard X-ray Nanoprobe at the U.S. Department of Energy's (DOE) Argonne National Laboratory is one of the world's most powerful x-ray microscopes.   view more (2008-06-25)

University of Pennsylvania Engineers Reveal What Makes Diamonds Slippery at the Nanoscale
They call diamonds "ice," and not just because they sparkle. Engineers and physicists have long studied diamond because even though the material is as hard as an ice ball to the head, diamond slips and slides with remarkably low friction, making it an ideal material or coating for seals,... view more (2008-06-24)

A novel X-ray source could be brightest in the world
The future of high-intensity x-ray science has never been brighter now that scientists at U.S. Department of Energy's Argonne National Laboratory have devised a new type of next generation light sources.   view more (2008-06-23)

GLAST Safely in Orbit, Getting Check-ups
Less than a week after launch, NASA's Gamma-ray Large Area Space Telescope, or GLAST, is safely up-and-running well in orbit approximately 350 miles (565 kilometers) above Earth's surface.   view more (2008-06-20)

Black holes have simple feeding habits
The biggest black holes may feed just like the smallest ones, according to data from NASA's Chandra X-ray Observatory and ground-based telescopes. This discovery supports the implication of Einstein's relativity theory that black holes of all sizes have similar properties, and will be useful for... view more (2008-06-19)

Weight loss after gastric bypass surgery may protect against infection and cancer
Another health benefit of bariatric weight-loss surgery may be a heightened immune defense against cancer and infections, a new study suggests. The results will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco.   view more (2008-06-18)

1 patient's account of becoming a live kidney donor
Annabel Ferriman, an editor at the BMJ, gives a frank first person account of her journey through the "protracted" and sometimes "frustrating" process of becoming a live kidney donor to her friend, Ray, who had been suffering from polycystic kidney disease for eight years.   view more (2008-06-16)

UC San Diego Physicists Reveal Secrets of Newest Form of Carbon
Using one of the world's most powerful sources of man-made radiation, physicists from UC San Diego, Columbia University and Lawrence Berkeley National Laboratory have uncovered new secrets about the properties of graphene-a form of pure carbon that may one day replace the silicon in computers,... view more (2008-06-11)

UC Santa Cruz physicists eagerly await launch of NASA space telescope they helped build
When NASA launches its newest space observatory, physicists at the University of California, Santa Cruz, will be watching as the product of nearly 16 years of hard work blasts into orbit.   view more (2008-05-30)

X-rays Often Repeated for Patients in Developing Countries
Patients in developing countries often need to have X-ray examinations repeated so that doctors have the image quality they need for useful medical diagnosis, the IAEA is learning. The findings come from a survey involving thousands of patients in 45 hospitals and 12 countries of Africa, Asia and... view more (2008-05-29)

CSI: Milky Way team works scene of dead star
Like a team of forensic detectives in a television show that could be called "CSI: Milky Way," a University of Chicago astrophysicist and his associates are piecing together how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more... view more (2008-05-29)
