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)

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... view more (2002-10-11)

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)

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)

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)

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)

Protein target for diabetes drug regulates blood pressure
University of Iowa researchers have identified a molecular pathway in blood vessels that controls blood pressure and vascular function and may help explain why certain drugs for type II diabetes also appear to lower patients' blood pressure. The study is published in the March 5 issue of Cell... view more (2008-03-05)

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)

The Last Cry Of Matter
'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be... view more (2003-11-27)

Breaking the nanometer barrier in X-ray microscopy
Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height.   view more (2006-11-10)

New tool to measure speeding nuclei is a fast-beam first
An international collaboration at the Michigan State University National Superconducting Cyclotron Laboratory (NSCL) has demonstrated a new technique for studying particles traveling at one-third the speed of light.   view more (2007-07-19)

Living Metals
Using synchrotron x-ray microbeams, a research team from the Max Planck Institute for Metals Research in Stuttgart and the ESRF has been able to observe for the first time that the microscopic structure of a crystalline material fluctuates in time. The results are published today in Science Express... view more (2005-04-22)

Novel asthma inhaler shortlisted for award
A novel asthma inhaler invented by Dr Ray Bacon of the University's Medical and Bioengineering Group, based at the Southampton General Hospital, has been shortlisted for this year's Royal Academy of Engineering MacRobert Award.   view more (1998-09-04)

Gamma Knife offers non-invasive treatment for vascular disorders, tumors in the brain
A week after graduating from high school, Katherine Coit had brain surgery to remove an abnormal tangle of blood vessels that were bleeding in her brain.   view more (2006-09-08)

Blow for hair link to breast cancer
The promising link between certain properties in human hair which could have potentially helped in diagnosis of breast cancer is "dubious" according to research published today in the Institute of Physics journal, Physics in Medicine and Biology. Dr Mark Sutton of the McGill University in Canada... view more (2002-04-26)

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)

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)

Mechanisms Involved with Tumor Relapse Identified
Researchers at Virginia Commonwealth University's Massey Cancer Center studying the interaction between the immune system and cancer cells have identified interferon gamma as one of the signaling proteins involved with tumor relapse.   view more (2007-03-14)

Safe water: simpler method for analyzing radium in water samples cuts testing time
A simpler technique for testing public drinking water samples for the presence of the radioactive element radium can dramatically reduce the amount of time required to conduct the sampling required by federal regulations. The U.S. Environmental Protection Agency (EPA) has approved use of the new... view more (2007-08-29)

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)

Space science technology takes airport security onto new level
A ground-breaking 'drive-through' scanner which screens for radioactive material is being developed to improve security at airports, ports and other significant buildings, thanks to a £99,000 investment from NESTA (the National Endowment for Science, Technology and the Arts), the organisation... view more (2004-10-19)
