NIST assists in solar stake-out to improve space weather forecasts
The sun is about to undergo unremitting scrutiny. About six times each minute of every hour for at least five years, a soon-to-be launched NASA satellite will measure the sun's quirky-and sometimes stormy-output of extreme ultraviolet (EUV) light. view more (2008-07-11)
Rare pancreatic cancer patients may live longer when treated with radiation therapy
Radiation therapy is effective in achieving local control and palliation in patients with pancreatic neuroendocrine tumors (PNTs), despite such tumors being commonly considered resistant to radiation therapy. view more (2009-11-23)
Sun exposure may trigger certain autoimmune diseases in women
Ultraviolet (UV) radiation from sunlight may be associated with the development of certain autoimmune diseases, particularly in women. view more (2009-07-31)
New study focuses on radiation-associated cancer risks
Concerns about the risk of radiation-induced cancer are growing with the increasing number of cancer patients surviving long term. view more (2007-01-12)
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)
Optimal adjuvant radiation therapy associated with improved survival, meta-analysis shows
A new analysis of adjuvant radiation therapy in women with breast cancer following mastectomy is associated with better survival as measured at 10 years when appropriate doses and fields of radiation are used. view more (2006-01-04)
IAU0916: The violent youth of solar proxies steer course of genesis of life
One of the hottest topics at this year's XXVIIth General Assembly of the International Astronomical Union (IAU) in Rio de Janeiro, Brazil involves the study of the astrophysical conditions favourable for the development and survival of primordial life. view more (2009-08-11)
Radiation after surgery doubles survival time for some lung cancer patients
Patients with lung cancer that has spread to mediastinal lymph nodes - located between the chest, breastbone and spine - who receive radiation after surgery and chemotherapy live twice as long as patients who do not receive radiation after surgery. view more (2006-11-07)
COMPOSITE PROCESS OPENS WINDOWS INTO SPACE
Window frames without joints and self-building space stations could be the outcome of a new way of processing composite materials. The technology, developed by Dr David Britnell and Dr Gordon Smith at Warwick University, means that fibre reinforced composites could be turned into shapes that are now very hard to manufacture. view more (1999-04-09)
Cleaning up pollutants with sunlight
A cheap, harmless chemical and sunlight could provide an environmentally friendly way of destroying micro-pollutants in the environment. UK researchers are developing a new type of reactor to destroy persistent contaminants such as pesticides and pharmaceutical residues. The technology, which breaks down the polluting molecules into carbon... view more... (2002-10-23)
New stars from old gas surprise astronomers
Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. view more (2009-02-19)
Controversial findings help explain evolution of life
Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry. view more (2006-04-07)
Does too much sun cause melanoma?
We are continuously bombarded with messages about the dangers of too much sun and the increased risk of melanoma (the less common and deadliest form of skin cancer), but are these dangers real, or is staying out of the sun causing us more harm than good? view more (2008-07-23)
CT Scans Increase Cancer Risk Estimates in Multiply-Imaged Emergency Department Patients
Physicians should review a patient's CT imaging history and cumulative radiation dose when considering whether to perform another CT exam. view more (2009-05-06)
Stressed crops emit more methane than thought
Scientists at the University of Calgary have found that methane emission by plants could be a bigger problem in global warming than previously thought. view more (2009-08-18)
New radiation protection technique results in reduced physician exposure
A new radiation protection technique can significantly reduce physician radiation exposure during coronary angiography, according to a researcher at the University of Maryland Medical Center in Baltimore, MD. view more (2006-05-03)
Men with prostate cancer avoid radiation due to misconceptions
Negative perceptions about radiation therapy can strongly influence a prostate cancer patient's choice to avoid external beam radiation therapy, even though studies have proven the treatment to be as safe and effective as other treatments for the disease, including surgery. view more (2006-11-06)
Radiation costs vary widely by delivery, U-M study finds
When cancer spreads to the bone, radiation treatments can help relieve the pain caused by the tumor. But how best to deliver the radiation may vary widely from one oncologist to the next. view more (2009-10-09)
Breakthrough in radiotherapy promises targeted cancer treatment
Current radiation therapy treatment damages a patient's healthy tissue as well as eradicating the tumour it is intended to destroy, making the treatment especially invasive and often causing nasty side effects. view more (2009-05-20)
Melanoma risk only partially associated vith exposure to UVB from sunlight
Researchers at The University of Texas M. D. Anderson Cancer Center have found that the risk of developing melanoma, the most deadly form of skin cancer, is only partially associated with exposure to ultraviolet B (UVB) radiation, the rays in sunlight that increase in summer and cause sunburn. view more (2005-12-21)
