Radiation dose reduction in liver cancer
A new digital angiography flat panel system reduces the radiation dose to patients undergoing interventional treatment for liver cancer by about one-fourth, a new study shows. view more (2005-10-03)
Modern radiation therapy ups lung cancer survival
Modern three-dimensional radiation therapy has been proven to be more successful at curing lung cancer than older two-dimensional radiation therapy for some patients with early stage lung cancer. view more (2006-09-01)
Jefferson researchers show chemotherapy and radiation together extend lung cancer patients' lives
Chemotherapy given at the same time as radiation therapy can help patients with a certain type of lung cancer live nearly 50 percent longer than they might have otherwise if the same treatment was given differently, according to an international team's analysis of several trial results. view more (2007-11-12)
A finite dodecahedral Universe
A franco-american quintet of cosmologists [1] conducted by Jean-Pierre Luminet, from Paris Observatory (LUTH), has proposed an original explanation to account for a surprising detail observed in the Cosmic Microwave Background (CMB) recently mapped by the NASA satellite WMAP. According to the team, who published their study in the 9 october 2003... view more... (2003-10-11)
Developmental drug may help bone fractures heal after radiation exposure
A drug currently under development by the University of Pittsburgh School of Medicine may help bone fractures heal more quickly after radiation exposure, according to a study by Pitt researchers. view more (2009-11-03)
High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four... view more...

A new unidentified very high energy gamma-ray source in our Galaxy
A European team based in Heidelberg (Germany) and their colleagues from the HEGRA collaboration have discovered a new, unidentified, very high energy gamma-ray source in our Galaxy. This source was detected via ground-based observations of the Imaging Atmosphere Cherenkov Telescope System. view more (2004-12-14)
Combining PET and CT scans makes cancer treatment more accurate
Doctors have discovered that combining images derived from positron emission tomography and computed tomography in the planning and delivery of radiation treatment for patients with head and neck cancer leads to more accurate delivery of the radiation dose and an increased chance for survival. view more (2006-05-02)
Precision radiation therapy yields rare success for liver tumors
Shaped-beam radiation therapy is a promising treatment for life-threatening metastatic liver tumors, according to researchers at the University of Rochester Medical Center who report an 88 percent success rate for controlling the lesions. view more (2005-10-20)
The Search for the Largest Particle Accelerator of the Universe Can Start
Earth is constantly bombarded with atomic nuclei from the universe. The energy of these particles ranges from very small values up to energies that are a hundred million times higher than those available in our particle accelerators (e.g. at CERN in Geneva or DESY in Hamburg). Actually, such particles should not even arrive on earth as they are... view more... (1999-03-25)
Prostate cancer patients see high survival rates with seed implants
More than ninety percent of men who receive appropriate radiation dose levels with permanent radiation seed implants to treat their prostate cancer are cured of their cancer eight years after diagnosis. view more (2007-02-01)
Some radiation therapy treatments can decrease fertility
In female cancer patients of reproductive age, radiation treatment directly to the ovaries should be avoided because there is a direct relationship between certain types of radiation therapy and fertility problems. view more (2009-04-02)
Antioxidants could provide all-purpose radiation protection
Two common dietary molecules found in legumes and bran could protect DNA from the harmful effects of radiation, researchers from the University of Maryland report. Inositol and inositol hexaphosphate (IP6) protected both human skin cells and a skin cancer-prone mouse from exposure to ultraviolet B (UVB) radiation, the damaging radiation found in... view more...

Early results favorable for 5-day radiation treatment of early stage prostate cancer
Preliminary results show that a shortened course of radiation therapy for prostate cancer called stereotactic body radiation therapy (SBRT) provides good PSA response for early-stage prostate cancer and has the same side effects as other treatments. view more (2009-03-16)
New NRPB Poster published for National Science Week - Sunsense: Protecting Yourself from Ultraviolet Radiation (UVR)
To co-incide with National Science Week (starting 8 March 2002) NRPB is publishing a new poster - Sunsense: Protecting Yourself from Ultraviolet Radiation (UVR). The poster provides important facts on protecting yourself from UVR. It summarises what is known about the health effects of UVR. The aim is to personalise the science behind a serious... view more... (2002-03-12)
Study suggests some breast cancer patients facing radiation after a mastectomy may be over-treated
A new study suggests standard radiation therapy for some breast cancer patients may not be medically required and may, therefore, be causing unnecessary serious side effects such as lymphedema and pulmonary problems. view more (2008-09-22)
Radiation Dose Drastically Reduced During Whole Chest MDCT
Emergency physicians who evaluate patients with non-specific chest pain using whole chest multi-detector CT (MDCT) combined with retrospective electrocardiogram (ECG) gating can reduce the patient radiation dose by 71% using MDCT combined with prospective ECG triggering instead. view more (2009-06-24)
Radiation therapy technique successfully treats pain in patients with advanced cancer
Stereotactic radiosurgery (SRS), a radiation therapy procedure pioneered at the University of Pittsburgh Cancer Institute (UPCI) that precisely delivers a large dose of radiation to tumors, effectively controls pain in patients with cancer that has spread to the spine. view more (2009-11-04)
1-step breast cancer treatment combines radiation, surgery
Princess Margaret Hospital (PMH) breast cancer specialists are using a new way to treat patients by delivering a one-time dose of radiation during surgery. view more (2007-06-20)
Ghost Remains After Black Hole Eruption
NASA's Chandra X-ray Observatory has found a cosmic "ghost" lurking around a distant supermassive black hole. This is the first detection of such a high-energy apparition, and scientists think it is evidence of a huge eruption produced by the black hole. view more (2009-05-29)
