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)
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)
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)
Small fluctuations in solar activity, large influence on the climate
Our sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. Nobody denies its influence on the natural climate variability, but climate models have, to-date, not been able to satisfactorily reconstruct its impact on climate activity. view more (2009-08-28)
Immune deficiency linked to a type of eye cancer
The incidence of squamous cell eye cancer is greater among kidney transplant patients and people with human immunodeficiency virus (HIV) than the general public, which suggests the disease is associated with immune deficiency. view more (2007-08-15)
Key molecule discovered in Venus's atmosphere
Venus Express has detected the molecule hydroxyl on another planet for the first time. This detection gives scientists an important new tool to unlock the workings of Venus's dense atmosphere. view more (2008-05-16)
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)
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)
OHSU Cancer Institute researcher: radiation, immunotherapy gives greater effectiveness
Oregon Health & Science University Cancer Institute researchers have found the right formula of radiation and immunotherapy for fighting lung cancer tumors in mice, which they hope will translate to better treatment in human lung cancers. view more (2008-09-26)
Researchers identify gene as protector of DNA, enemy of tumors
A single gene plays a pivotal role launching two DNA damage detection and repair pathways in the human genome, suggesting that it functions as a previously unidentified tumor suppressor gene. view more (2006-08-07)
3-D radiation treatment planning reduces feeding-tube use
Although current surgical techniques and multi-modality treatment regimens allow organ preservation for a growing number of patients with head and neck cancers, remaining dependent on a feeding tube after treatment is a major problem for these patients. view more (2006-11-06)
Researchers Find a Way to Reduce Patient Radiation Dose During Pulmonary CT Angiography
While screening for possible pulmonary emboli using pulmonary CT angiography, a new study shows that radiologists can effectively lower the patient radiation dose by approximately 44% and improve vascular enhancement without deterioration of image quality. view more (2009-07-01)
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...

Team develops new metamaterial device
An engineered metamaterial proved it can function as a state-of-the-art device in the complex terahertz range of the electromagnetic spectrum, setting a standard of performance for modulating tiny waves of radiation, according to a team of researchers from Boston College, the Los Alamos and Sandia national laboratories, and Boston University. view more (2009-02-25)
New insights into how lasers cut flesh
Lasers are at the cutting edge of surgery. From cosmetic to brain surgery, intense beams of coherent light are gradually replacing the steel scalpel for many procedures. view more (2007-10-26)
