Radiation costs vary widely by delivery, U-M study finds
When cancer spreads to the bone, radiation treatments can help relieve the pain caused by the tumor. But how best to deliver the radiation may vary widely from one oncologist to the next. view more (2009-10-09)
Breakthrough in radiotherapy promises targeted cancer treatment
Current radiation therapy treatment damages a patient's healthy tissue as well as eradicating the tumour it is intended to destroy, making the treatment especially invasive and often causing nasty side effects. view more (2009-05-20)
Introducing the 'coolest' spacecraft in the universe
The European Space Agency's (ESA) Planck mission, which will study the conditions present in our Universe shortly after the Big Bang, is reaching an important milestone with the integration of instruments into the satellite at Alcatel Alenia Space in Cannes, France. view more (2007-02-12)
Combination therapy shows improvement for breast cancer patients
Giving radiation therapy and chemotherapy at the same time after a lumpectomy helps keep breast cancer from returning locally. view more (2006-12-01)
New population of faint protogalaxies discovered
Astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15% of its present age. view more (2007-11-29)
NASA's Fermi Telescope Detects Gamma-Ray From
Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. view more (2009-11-03)
Iterative reconstruction technique significantly reduces patient radiation dose during CT scans
Computed tomography (CT) scans are responsible for more than two thirds of the total radiation dose associated with medical imaging exams. view more (2009-08-19)
Cool spacedust survey goes into orbit
University of Nottingham astronomers will be studying icy cosmic dust millions of light years away - using the biggest space telescope ever built. view more (2008-02-04)
Tackling the threat of nuclear terrorism
The only effective way to tackle the threat of nuclear terrorism is to abolish nuclear weapons and establish strict international control of all fissile materials that could be used to make new weapons, argue three US physicians in this week's BMJ. In the aftermath of 11 September 2001, nuclear terrorism has emerged as a real threat and could... view more... (2002-02-06)
Combination therapy reduces tumor resistance to radiation
Radiation is used to treat a variety of tumors and the response of tumors to radiation is dependent on endothelial cell death, which in turn limits oxygen delivery to the tumor, causing hypoxia and tumor cell death. view more (2007-06-08)
Largest PSA bounce study eases worry of prostate cancer returning
Prostate cancer patients who have a temporary rise in their prostate specific antigen (PSA) levels after radiation therapy-called a PSA bounce-are not at an increased risk of their cancer coming back any more than those who don't have a temporary rise. view more (2006-11-09)
MIT to lead development of new telescopes on moon
NASA has selected a proposal by an MIT-led team to develop plans for an array of radio telescopes on the far side of the moon that would probe the earliest formation of the basic structures of the universe. view more (2008-02-20)
Cancer Gene Radiation Therapy Discovery
Dr Tracy Robson, a lecturer in molecular radiation science at the University's Jordanstown campus, has isolated a novel gene, called DIR-1, which can alter a tumour cell's susceptibility to radiation therapy. view more (1999-09-20)
Physicists find evidence for highest energy photons ever detected from Milky Way's equator
Physicists at nearly a dozen research institutions, including New York University, have discovered evidence for very high energy gamma rays emitting from the Milky Way, marking the highest energies ever detected from the galactic equator. view more (2005-12-14)
Experimental agents may prevent radiation-induced leukemia
Treatment with biphosphonates could prevent radiation-induced leukemia, according to data presented at the American Association for Cancer Research 100th Annual Meeting 2009. view more (2009-04-20)
Cosmic rays detected deep underground reveal secrets of the upper atmosphere
Cosmic-rays detected half a mile underground in a disused U.S. iron-mine can be used to detect major weather events occurring 20 miles up in the Earth's upper atmosphere, a new study has revealed. view more (2009-01-22)
Towards predicting late-stage radiation toxicity
Radiation is a brutal and in many cases necessary part of cancer therapy. More 50% of cancer patients receive radiotherapy as part of their treatment, and many experience concurrent negative side effects. view more (2006-10-31)
University Scientists Will Not See the Eclipse...At Least, Not With Their Eyes!
The sun constantly radiates energy across the spectrum of frequencies from radio, through heat, to visible light and beyond. During the period of totality, only radiation present in the sun's annular corona will be detectable, with energy directly radiated from the sun being masked by the moon. view more (1999-08-06)
Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor. view more (2005-11-16)
Order of chemotherapy, radiation has no effect on breast cancer survival
For women who have had surgery for early breast cancer, it may not matter whether they receive follow-up chemotherapy before, after or during radiation therapy, according to a new review of studies. view more (2006-10-31)
