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)

Scientists Find Giant Ring Encircling Exotic Dead Star
One of the most powerful eruptions in the universe might have spun an infrared ring around a rare and exotic star known as a magnetar, a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.   view more (2008-05-29)

Supernova birth seen for first time
Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time.   view more (2008-05-22)

A scientific first: A supernova explosion is observed in real time
An ordinary observation with NASA's Swift research satellite recently led to the first real-time sighting of a star in the process of exploding. Astronomers have surveyed thousands of these supernova explosions in the past, but their observations have always begun some time after the main event is... view more (2008-05-22)

Observation of X-rays from birth of supernova leads to all-out effort to record stellar death
The lucky capture in January of an X-ray outburst from the very beginning of a supernova allowed astronomers around the world to quickly follow up with ground-based telescopes and collect a wealth of new information on early processes in stellar explosions, according to a paper newly submitted to... view more (2008-05-22)

NASA's Swift satellite catches first 'normal' supernova in the act of exploding
Thanks to a fortunate observation with NASA's Swift satellite, astronomers, for the first time, have caught a normal supernova at the moment of its birth--the first instant when an exploding star begins spewing its energy into space, transforming into a supernova that during its brief lifetime will... view more (2008-05-22)

Common star draws swift attention with unprecedented flare
On April 25, one of our nearest stellar neighbors, a small, faint red dwarf known as EV Lacertae, unleashed the brightest flare ever detected from a normal star outside our solar system.   view more (2008-05-20)

The Mouse That Roared: Pipsqueak Star Unleashes Monster Flare
On April 25, NASA's Swift satellite picked up the brightest flare ever seen from a normal star other than our Sun. The flare, an explosive release of energy from a star, packed the power of thousands of solar flares. It would have been visible to the naked eye if the star had been easily observable... view more (2008-05-20)

Novel enzyme inhibitor paves way for new cancer drug
Combining natural organic atoms with metal complexes, scientists at The Wistar Institute have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development.   view more (2008-05-16)

Discovery of most recent supernova in our galaxy
The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy.   view more (2008-05-15)

Argonne scientists use lasers to align molecules
Protein crystallographers have only scratched the surface of the human proteins important for drug interactions because of difficulties crystallizing the molecules for synchrotron x-ray diffraction.   view more (2008-05-14)

New Clues to How Proteins Dissolve and Crystallize
In the late 19th century the Czech scientist Franz Hofmeister observed that some salts (ionic compounds) aided the solution of proteins in egg white, some caused the proteins to destabilize and precipitate, and others ranged in activity between these poles.   view more (2008-05-13)

Immune system pathway identified to fight allergens, asthma
For the first time, researchers from the University of Pittsburgh School of Medicine have identified genetic components of dendritic cells that are key to asthma and allergy-related immune response malfunction.   view more (2008-05-08)

X-rays power discoveries at Chicago's Field Museum
Digital medical imaging and information technology from Carestream Health, Inc., is playing a key role in helping The Field Museum of Chicago discover and analyze secrets hidden within its world-class collections.   view more (2008-05-07)
