High-dose radiation reduces risk of prostate cancer recurrence
Men with localized prostate cancer who received high-dose external radiation therapy were less likely to have cancer recurrence than men who received conventional-dose radiation therapy. view more (2005-09-14)
Researchers find how a common genetic mutation makes cancer radiation resistant
Many cancerous tumors possess a genetic mutation that disables a tumor suppressor called PTEN. Now researchers at Washington University School of Medicine in St. Louis have shown why inactivation of PTEN allows tumors to resist radiation therapy. view more (2009-06-10)
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)
Caltech researchers interpret asymmetry in early universe
The Big Bang is widely considered to have obliterated any trace of what came before. Now, astrophysicists at the California Institute of Technology (Caltech) think that their new theoretical interpretation of an imprint from the earliest stages of the universe may also shed light on what came before. view more (2008-12-17)
Cetuximab with radiotherapy does not increase side effects for head and neck cancer patients
The addition of Cetuximab (brand name Erbitux) to radiation therapy treatments does not increase the rate or duration of some side effects in the treatment of advanced head and neck cancers. view more (2007-01-19)
Nanoparticles + light = dead tumor cells
Medical physicists at the University of Virginia have created a novel way to kill tumor cells using nanoparticles and light. view more (2008-07-30)
Different method of evaluating the urinary tract system reduces radiation dose
The split-bolus (cross sectional imaging) MDCT urography technique reduces both radiation dose and number of images produced, according to a recent study conducted by radiologists from Stanford University School of Medicine in Stanford, CA and VA Palo Alto Health Care System in Palo Alto, CA. view more (2007-08-29)
Cosmic thermostats provide clue to 30 year old astronomy puzzle (Embargoed until 1900 hrs London time Wednesday 17 July 2002)
A cosmic phenomenon involving pockets of hot gas in space which appear not to cool down has been puzzling astronomers for three decades. Now new research by Dr Christian Kaiser at the University of Southampton and Professor Marcus Brüggen of the International University Bremen, Germany, shows that the energy of the hot gas is actually... view more...

Precise picture of early Universe supports 'dark matter' theory
A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist. view more (2009-11-03)
New Model Developed to Estimate Radiation Skin Doses during CT Guided Interventional Procedures
A new model that would allow interventional radiologists (radiologists who specialize in fine needle aspiration, fine needle biopsy and radiofrequency ablation) to better estimate patient radiation skin doses during CT guided interventional procedures has been developed. view more (2008-11-04)
External beam partial breast irradiation most cost-effective treatment
External beam partial breast irradiation (EB-PBI) is the most cost-effective method for treating postmenopausal women with early-stage breast cancer based on utilities, recurrence risks and costs when compared to whole breast radiotherapy (WBRT) and brachytherapy partial breast irradiation (brachy-PBI). view more (2009-06-03)
New way of tracking muscle damage from radiation
Magnetic resonance imaging (MRI) could become a valuable tool for predicting the risk of muscle injury during and following radiation therapy. view more (2006-11-07)
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight. view more (2008-08-25)
New Insight into the Cosmic Renaissance Epoch
VLT Discovers a Group of Early Inhabitants and Find Signs of Many More [1] Using the ESO Very Large Telescope (VLT), two astronomers from Germany and the UK [2] have discovered some of the most distant galaxies ever seen. They are located about 12,600 million light-years away. It has taken the light now recorded by the VLT about nine-tenths of the... view more... (2003-08-21)
Supernovae-Cosmic Lighthouses
Supernovae stand out in the sky like cosmic lighthouses. Scientists at the Max Planck Institute for Astrophysics and at the National Astronomical Institute of Italy have now found a way to use these cosmic beacons to measure distances in space more accurately. view more (2007-02-12)
UAB First in U.S. to Offer Speedier Precise Cancer Therapy
The University of Alabama at Birmingham (UAB) this month became the first U.S. medical center to offer a speedier cancer radiation therapy. The new technique can turn a 20-minute radiotherapy session into a 90-second session for selected patients. view more (2008-05-08)
Doses from Discharges now in electronic format
Doses from Discharges is the latest electronic module, based on the NRPB At-a-Glance printed series of broadsheets, to appear on the NRPB website (http://www.nrpb.org/understand/index.htm). Modules for Radon, Transport of Radioactive Materials and Nuclear Emergencies are already to be found on the website, in the Understanding Radiation section,... view more... (2003-03-07)
Hazards of CT scans overstated
Concerns over possible radiation effects of CT scans detailed in a report yesterday in the New England Journal of Medicine should not scare people away from getting medically needed CT scans, as the scans play a critical role in saving the lives of thousands of people every day. view more (2007-12-03)
Dust-enshrouded star looks similar to our sun
Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth. view more (2005-07-21)
Cost-benefit analysis: Combo treatment costs more, saves money later
From a health insurer's perspective, the most effective cancer treatment may also be the most cost-effective. view more (2006-11-08)
