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)

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)

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 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 in the night sky at the time.   view more (2008-05-20)

Hotter than expected neutron star surfaces help explain superburst frequency
A new theoretical thermometer built from heavy-duty mathematics and computer code suggests that the surfaces of certain neutron stars run significantly hotter than previously expected. Hot enough, in fact, to at least partially answer an open question in astrophysics — how to explain the observed frequency of ultra-violent explosions known... view more... (2007-04-16)

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)

Celebrating 5 years of the Very Large Telescope
From Sombreros to the Centre of the Milky Way Celebrating 5 years of the Very Large Telescope One of the world's most advanced telescope facilities, Very Large Telescope (VLT), situated in the Atacama Desert in Chile, celebrates its 5th birthday today (1st April 2004). During its short history the telescope has captured some breathtaking images... view more... (2004-03-31)

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)

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 intense than Earth's.   view more (2008-05-29)

Billions of particles of anti-matter created in laboratory
ake a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma "jet."   view more (2008-11-18)

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)

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)

Sporadic play activity as beneficial to child health as continuous bouts of exercise, study suggests
New research suggests for the first time that frequent bouts of sporadic activity could be just as beneficial to children's health as longer exercise sessions.   view more (2009-05-11)
