NASA's Swift Spies Comet Lulin
While waiting for high-energy outbursts and cosmic explosions, NASA's Swift Gamma-ray Explorer satellite is monitoring Comet Lulin as it closes on Earth. For the first time, astronomers are seeing simultaneous ultraviolet and X-ray images of a comet. view more (2009-02-23)
Discovery confirms explosive prediction made by astrophysicists in 1999
NASA's Swift satellite and ground-based telescopes have discovered the most distant exploding star on record, confirming a 1999 prediction made by University of Chicago astrophysicist Don Lamb and Daniel Reichart, who was then a graduate student at Chicago. view more (2005-09-13)
Healthy human immune system cells can respond to HIV-1
AIDS patients' failure to clear HIV-1 might not be due to the inability of the human immune system to recognise the virus, as was previously thought. view more (2006-05-18)
Scientists predict how to detect a fourth dimension of space
Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity. view more (2006-05-26)
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 underway. view more (2008-05-22)
Poxvirus Potency Uncovered in New Atomic Map
Scientists at the University of Alabama at Birmingham (UAB) and Saint Louis University used X-ray crystallography to uncover new details about the infectious potency of poxviruses, furthering the understanding of how viral infections can subvert the body's immune system. view more (2008-02-04)
Alzheimer's disease drug treats traumatic brain injury, report GUMC researchers
The destructive cellular pathways activated in Alzheimer's disease are also triggered following traumatic brain injury, say researchers from Georgetown University Medical Center (GUMC). view more (2009-07-13)
The Effect of Gamma Waves on Cognitive and Language Skills in Children
New studies conducted by April Benasich, professor of neuroscience at Rutgers University in Newark, and her colleagues reveal that gamma wave activity in the brains of children provide a window into their cognitive development, and could open the way for more effective intervention for those likely to experience language problems. view more (2008-10-22)
Exploding star takes astronomers by surprise
A partially exploding star, known as a nova, has recovered more quickly than expected, say scientists who have analysed new data from the ESA`s XMM-Newton X-ray satellite. Nova explosions are not completely destructive phenomena. In fact, after an explosion occurs, the star recovers and starts shining again. Until now, astronomers have not known... view more...

NASA celebrates Chandra X-Ray Observatory's 10th anniversary
Ten years ago, on July 23, 1999, NASA's Chandra X-ray Observatory was launched aboard the space shuttle Columbia and deployed into orbit. view more (2009-07-24)
Climate change -- research suggests it is not a swindle
New research has dealt a blow to the skeptics who argue that climate change is all due to cosmic rays rather than to man-made greenhouse gases. The new evidence shows no reliable connection between the cosmic ray intensity and cloud cover. view more (2008-04-03)
Resolving a galactic mystery
An extremely deep Chandra X-ray Observatory image of a region near the center of our Galaxy has resolved a long-standing mystery about an X-ray glow along the plane of the Galaxy. view more (2009-04-30)
New pathway could present an intervention point for cancer treatment
A new cellular pathway leads to destruction of a protein that promotes growth of breast, prostate and similar cancers and could provide a new avenue through which to pursue treatment of such diseases. view more (2006-01-27)
Sunnybrook researchers identify which sets of molecules are required to induce T cells
Researchers at Sunnybrook Health Sciences Centre have made a critical discovery in T cell development bringing immunologists one step closer to enabling the creation of tailored T cell therapy that could one day be used to treat patients with AIDS or other immune system deficiencies. view more (2006-07-26)
Penn Scientists Map Molecular Regulation of Fat-Cell Genetics
A research team led by Mitchell Lazar, MD, PhD, Director of the Institute for Diabetes, Obesity, and Metabolism at the University of Pennsylvania School of Medicine, has used state-of-the-art genetic technology to map thousands of positions where a molecular "master regulator" of fat-cell biology is nestled in DNA to control genes in... view more...

ESF workshop makes major advance in cancer radiotherapy
Radical improvements in outcome for many cancer sufferers are in prospect following one of the most significant advances in radiotherapy since x-rays were first used to treat a tumour in 1904. view more (2008-11-07)
NASA's Swift Looks to Comets for a Cool View
NASA's Swift Gamma-ray Explorer satellite rocketed into space in 2004 on a mission to study some of the highest-energy events in the universe. view more (2008-12-04)
Advances in breast imaging
A diagnostic device that resembles a mammography unit can detect breast tumors as tiny as one-fifth of an inch in diameter, which may make it a valuable complementary imaging technique to mammography. view more (2006-12-18)
Anthrax test, developed by army and CDC, receives FDA approval
A method for identifying Bacillus anthracis, the causative agent of anthrax, has been cleared for diagnostic use by the U.S. Food and Drug Administration (FDA). view more (2005-08-31)
Slow brain waves play key role in coordinating complex activity
While it is widely accepted that the output of nerve cells carries information between regions of the brain, it's a big mystery how widely separated regions of the cortex involving billions of cells are linked together to coordinate complex activity. view more (2006-09-15)
