Positioning pelvic cancer patients on stomachs for radiation yields better results
Oregon Health & Science University Cancer Institute researchers have found that positioning pelvic cancer patients on their stomachs rather than their backs is a better method for delivering radiation therapy. view more (2007-10-29)
Lunar Reconnaissance Orbiter's LAMP shedding light on permanently shadowed regions of the Moon
NASA's Lunar Reconnaissance Orbiter (LRO), launched on June 18 of this year, has begun its extensive exploration of the lunar environment and will return more data about the Moon than any previous mission. view more (2009-09-18)
One day radiation may become an option for breast cancer patients
Doctors in Canada are studying the effectiveness of permanent radiation seed implants following lumpectomy as an alternative to whole or partial breast irradiation for early-stage breast cancer patients. view more (2006-01-04)
Patient' exposure to radiation significantly lower when using new cardiac CT technique
A new cardiac CT technique, prospective gated 64-channel cardiac CT, has a significantly lower radiation dose and produces CT coronary angiograms with better image quality when compared with the standard retrospective ECG gating. view more (2008-04-14)
Rapidly rising PSA before treatment is key indicator of cancer spread
Results of a new Fox Chase Cancer Center study show that men with a rapidly rising PSA level before treatment have a high probability of metastatic disease and should receive hormone therapy in addition to radiation. view more (2006-11-09)
Researchers study effects of Aricept in pediatric brain cancer survivors
A pediatric oncologist at Brenner Children's Hospital is evaluating whether a drug typically used to treat Alzheimer's patients will help brain cancer survivors avoid the learning and memory problems that are common after radiation therapy. view more (2006-11-06)
A boost for bamboo-based blouses and blankets
Rising interest in "sustainable" fabrics is fostering a bamboo boom, in which bamboo-based fabrics are hitting the market as a leading eco-friendly textile. view more (2008-04-07)
Could vitamin D save us from radiation?
Radiological health expert Daniel Hayes, Ph.D., of the New York City Department of Health and Mental Hygiene suggests that a form of vitamin D could be one of our body's main protections against damage from low levels of radiation. view more (2008-11-10)
Common aquatic animals show extreme resistance to radiation
Scientists at Harvard University have found that a common class of freshwater invertebrate animals called bdelloid rotifers are extraordinarily resistant to ionizing radiation, surviving and continuing to reproduce after doses of gamma radiation much greater than that tolerated by any other animal species studied to date. view more (2008-03-26)
OU Part of International Study on Genetic Impact of Radiation
Researchers at the University of Oklahoma Health Sciences Center are helping to lead a massive international study on the possible genetic effects of radiation and cancer drug exposures on future generations. view more (2009-10-08)
Angled gantry technique reduced breast radiation exposure by 50 percent
A novel angled gantry approach to coronary CT angiography reduced radiation exposure to the breast by more than 50%, according to Thomas Jefferson University researchers. view more (2008-12-04)
New Laser Technique Advances Nanofabrication Process
The ability to create tiny patterns is essential to the fabrication of computer chips and many other current and potential applications of nanotechnology. view more (2009-04-10)
Jefferson oncologists show focused radiation is effective as surgery against nerve tumor
Specifically aimed, "stereotactic" radiation may be as good as surgery - and in some cases, even better - in treating benign but potentially devastating brain tumors called non-acoustic schwannomas. view more (2007-10-31)
Extra radiation dose prevents breast cancer return in young women
Women 40 years and younger with early-stage breast cancer who receive an additional high dose of radiation (boost dose) after undergoing breast-conserving surgery (lumpectomy) and standard radiation treatment are almost twice as likely to be free of cancer 10 years after treatment compared to those who don't receive the boost dose. view more (2007-10-30)
At the limits of the photoelectric effect
By way of the classical photoeffect, Einstein proved in 1905 that light also has particle character. However, with extremely high light intensities, remarkable things happen in the process. view more (2009-04-24)
ESA studies the Sun-Earth climate link
Meteorologists can no longer view the Earth as an isolated system. Both long-term climate changes and day-to-day weather show links with the Sun`s activity. Scientists therefore study the nature of those links intensely. With data from ESA`s spaceprobes SOHO, Cluster, and Ulysses, we now have the information we need to solve the mystery of how the... view more... (2002-08-23)
Timing of radiation treatments for colon cancer may need adjusting, Jefferson researchers say
Scientists have unexpectedly discovered that mice with the gene defect that causes colon cancer in humans can differ from normal mice in how they respond to radiation treatments. view more (2006-04-10)
Intravenous chemoradiation effective for inoperable head, neck cancer; easier for patients, doctors
Chemoradiation (radiation and chemotherapy given at the same time) given through a needle or tube inserted into a vein (intravenous) is as effective as treatment given directly to the tumor through a tube inserted into an artery (intra-arterial) for patients with inoperable head and neck cancer. view more (2006-11-07)
Black holes, galaxies young and old visible in massive mapping of the night sky
Color images documenting the past 10 billion years of galactic evolution were distributed online this week as part of the first public release of data from a massive project to map a distant region of the universe that combines the efforts of nearly 100 researchers from around the world, including the University of Pittsburgh. view more (2007-10-04)
Men continue to have normal life after radiation for prostate cancer
Men receiving radiation therapy to combat early-stage prostate cancer are still able to achieve an erection and face a low rate of incontinence one year following treatment, according to a new study published in the July 15, 2005 issue of the International Journal of Radiation OncologyBiologyPhysics, the official journal of ASTRO,... view more...
