X-ray satellites discover the biggest collisions in the Universe
The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought.   view more (2007-07-18)

Malaria-resistant mosquitoes battle disease with 'molecular warhead'
A team led by UT Southwestern Medical Center researchers has discovered why some mosquitoes are resistant to malaria, a finding that may one day help fight a disease that afflicts and kills millions of people.   view more (2007-07-09)

UCLA's Christopher Russell leads NASA's Dawn Mission, set for July 7 launch
Christopher T. Russell, UCLA professor of geophysics and space physics, has spent 15 years working on NASA's Dawn mission to the doughnut-shaped asteroid belt between Mars and Jupiter. As the scheduled July 7 launch from Cape Canaveral nears, Russell is ready, and so is Dawn.   view more (2007-06-28)

Neutron stars join the black hole jet set
NASA's Chandra X-ray Observatory has revealed an X-ray jet blasting away from a neutron star in a binary system.   view more (2007-06-28)

Alzheimer's-associated enzyme can disrupt neural activity in the brain
An enzyme involved in the formation of the amyloid-beta protein associated with Alzheimer's disease can also alter the mechanism by which signals are transmitted between brain cells, the disruption of which can cause seizures.   view more (2007-06-18)

Nanoparticles unlock the future of superalloy metals
Sandia National Laboratories is pioneering the future of superalloy materials by advancing the science behind how those superalloys are made.   view more (2007-06-14)

Newer contrast agents safe for children
Allergic-like reactions to newer iodine-containing contrast agents (nonionic contrast media), are rare in children according to a recent study conducted by researchers from the University of Michigan Medical Center and C.S. Mott Children's Hospital both in Ann Arbor.   view more (2007-06-08)

XMM-Newton reveals X-rays from gas streams around young stars
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays.   view more (2007-06-01)

Galaxy Cluster Takes It to the Extreme
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA's Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected.   view more (2007-05-31)

Common treatment for methamphetamine overdose may damage brain cells
A common antipsychotic drug used in emergency rooms to treat methamphetamine overdose damages nerve cells in an area of the brain known to regulate movement, a new study shows.   view more (2007-05-30)

Dynamic sonography accurate in diagnosing muscle tears
Dynamic sonography is useful in the diagnosis, management and follow-up of muscle tears and hematomas, according to a recent study conducted by researchers from Khoula Hospital in Muscat, Oman.   view more (2007-05-25)

A Brown Dwarf Joins the Jet-Set
Jets of matter have been discovered around a very low mass 'failed star', mimicking a process seen in young stars. This suggests that these 'brown dwarfs' form in a similar manner to normal stars but also that outflows are driven out by objects as massive as hundreds of millions of solar masses... view more (2007-05-24)

Quasicrystals: Somewhere between order and disorder
In new research that's available online and slated for publication in July's issue of the Journal of the American Mathematical Society, Damanik and colleague Serguei Tcheremchantsev offer a key proof in the study of quasicrystals, crystal-like materials whose atoms don't line up in neat, unbroken... view more (2007-05-24)

Yoga and elevated brain GABA levels
Researchers at Boston University School of Medicine (BUSM) and McLean Hospital have found that practicing yoga may elevate brain gamma-aminobutyric (GABA) levels, the brain's primary inhibitory neurotransmitter.   view more (2007-05-22)

New technique for 'weighing' black holes
ESA's XMM-Newton has helped to find evidence for the existence of controversial Intermediate Mass Black Holes. Scientists used a new, recently proven method for determining the mass of black holes.   view more (2007-05-17)

X-rays provide a new way to investigate exploding stars
ESA's X-ray observatory XMM-Newton has revealed a new class of exploding stars - where the X-ray emission 'lives fast and dies young'.   view more (2007-05-10)

Diabetes drug dramatically boosts power of platinum chemotherapy
A widely used diabetes drug dramatically boosted the potency of platinum-based cancer drugs when administered together to a variety of cancer cell lines and to mice with tumors, scientists from Dana-Farber Cancer Institute report.   view more (2007-05-08)

NASA's Chandra sees brightest supernova ever
The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes.   view more (2007-05-08)

Largest, brightest supernova ever seen may be long-sought pair-instability supernova
An exploding star first observed last September is the largest and most luminous supernova ever seen, according to University of California, Berkeley, astronomers, and may be the first example of a type of massive exploding star rare today but probably common in the very early universe.   view more (2007-05-08)

High intracoronary attenuation improves accuracy of 64-slice CT-CA
High intracoronary attenuation significantly improves diagnostic accuracy in 64-slice CT-CA of the coronary arteries.   view more (2007-05-07)

CT better than plain radiographs in diagnosing lumbar spine fractures
Lumbar spine fractures in a majority of patients with trauma can be detected by routine trauma abdomen and pelvis CT compared to plain radiographs, according to a recent study conducted by radiologists at the University of Cincinnati in Cincinnati, OH.   view more (2007-05-07)

Extremely low-dose MDCT useful for reducing hospital stay for patients with acute abdominal pain
Extremely low-dose MDCT of the abdomen and pelvis is useful in providing needed diagnostic information and reducing hospital stay in patients with acute nonspecific abdominal pain.   view more (2007-05-07)

MR imaging helps predict recurrence in prostate cancer patients
