Inside job: new radioactive agents for colon cancer work inside cells
Johns Hopkins scientists have developed a potentially novel way to fight colorectal cancer using tiny molecules to deliver potent barrages of radiation inside cancer cells, unlike current treatments that bind to the surface of cells and attack from the outside and cause unwanted side effects. view more (2007-10-10)
Supernova radiation simulated in Virtual Reality
To astrophysicists, the energy-charged x-ray radiation on the fringes of a supernova explosion has long been enigmatic. It hasn't been possible to explain how the electrons are able to accelerate to nearly the speed of light. Now scientists in England and in Linköping, Sweden, have hit upon a possible explanation by combining supercomputer... view more... (2001-12-20)
Normal tissue not spared in new forms of breast cancer radiotherapy
A five day course of radiotherapy to treat breast cancer may, in some cases, expose as much lung and heart tissue to potentially toxic radiation as does the standard six weeks of treatment, say researchers at Mayo Clinic Jacksonville. view more (2007-10-31)
How low can you go? - The Society for Radiological Protection 40th anniversary meeting
Media Invitation How low can you go? The Society for Radiological Protection 40th anniversary meeting, ALARP (As Low as Reasonably Practicable): Principles and Practices 2 - 4 April 2003 Emergency surveillance situations, nuclear decommissioning and airline travel are just a few of the topics to be discussed at The Society for Radiological... view more...

PMH finding may help some tonsil cancer patients avoid chemotherapy
Clinical researchers at Princess Margaret Hospital (PMH) have confirmed that patients with oropharyngeal squamous cell cancer ("tonsil cancer") harbour a common type of human papilloma virus (HPV16), but also that such cancers are very sensitive to radiation. view more (2009-11-04)
Pediatric Patient Body Shape May Play a Key Role in Decreasing Radiation Dose During CT Scans
Manipulation of kVp (kilovoltage peak) and mAs (tube current flow) according to a patient's body shape may help reduce radiation doses in pediatric patients during CT, according to a study performed at the Cleveland Clinic Children's Hospital in Cleveland, OH. view more (2009-04-24)
M. D. Anderson study finds racial disparities in radiation therapy rates for breast cancer
Black women are less likely than white women to receive radiation therapy after a lumpectomy, the standard of care for early stage breast cancer, according to a new study by researchers at The University of Texas M. D. Anderson Cancer Center. view more (2008-09-04)
Missions to Mars
The European Space Agency (ESA) has chosen the GSI accelerator facility to assess radiation risks that astronauts will be exposed to on a Mars mission. view more (2008-04-15)
Surgery remans an option for advanced lung cancer
In recent years, oncologists have debated whether patients with a certain type of advanced lung cancer would benefit from surgery. view more (2009-07-27)
Jefferson oncologists show less radiation just as effective in fighting brain tumor, saving hearing
Radiation oncologists at the Kimmel Cancer Center at Thomas Jefferson University and Thomas Jefferson University Hospital in Philadelphia have found that giving less radiation than usual is just as effective against a benign but potential devastating brain tumor called an acoustic schwannoma, and better yet, might save more of the patient's... view more...

Treatment for early prostate cancer associated with type of specialist seen
A new study analyzing men with localized prostate cancer shows that the specialty of the physician they see can influence the type of therapy they ultimately receive. view more (2007-06-04)
Water vapor feedback is rapidly warming Europe
A new report indicates that the vast majority of the rapid temperature increase recently observed in Europe is likely due to an unexpected greenhouse gas: water vapor. view more (2005-11-09)
Chemotherapy gel may fight breast cancer and reduce breast deformity
Women who undergo surgery for breast cancer followed by radiation therapy often experience breast deformities that can only be corrected through reconstructive surgery. view more (2006-04-25)
Chemo-radiation before prostate removal may prevent cancer recurrence
Researchers in the Oregon Health & Science University Knight Cancer Institute and the Portland Veterans Affairs Medical Center have found a combination of radiation therapy and chemotherapy given before prostate removal is safe and may have the potential to reduce cancer recurrence and improve patient survival. view more (2009-11-05)
Gene therapy protects mice from the effects of whole-body irradiation
University of Pittsburgh School of Medicine researchers have successfully protected mice against the damaging effects that radiation can have on bone marrow using gene therapy. view more (2006-06-05)
Ideal doses of IMRT defined to reduce treatment side effects for head and neck cancer
Results from a University of Pittsburgh study evaluating intensity modulated radiation therapy (IMRT) for head and neck cancer determined the ideal doses for lessening treatment side effects. view more (2005-10-19)
PTB Terahertz calibration satisfies US laser manufacturer
Terahertz radiation still lies in a metrological no man's land - a metrology gap. The Physikalisch-Technische Bundesanstalt (PTB) can now close this gap. view more (2009-11-06)
Mind the gap: Space scientists uncover causes of gap in Van Allen belts
A team of British and US scientists have discovered that the gap in the Van Allen radiation belts is formed by natural wave turbulence in space, not by lightning. view more (2006-09-27)
