Extremely low dose CT coronary angiography shows promise in assessing cardiac function
Extremely low dose CT coronary angiography can be used to measure cardiac function and has the potential for use when other commonly used examinations are limited, a preliminary study indicates. view more (2008-04-14)
A tiny protein plays a big role in DNA repair
Two of DNA's worst enemies, ultraviolet light and chemical carcinogens, can wreak havoc on the molecule by mutating individual nucleotides or changing its physical structure. view more (2006-05-09)
New deep space images of distant strip of sky to be available on Google
A global project to map a distant strip of the universe is releasing its data today to scientists and the public to be used as part of Google Sky, a new feature of Google Earth. view more (2007-10-04)
Exercise can aid recovery after brain radiation
Exercise is a key factor in improving both memory and mood after whole-brain radiation treatments in rodents, according to data presented by Duke University scientists at the Society for Neuroscience meeting. view more (2009-10-19)
Scientific breakthrough will help protect astronauts and spacecraft
A breakthrough by a team of British, US and French scientists will help protect astronauts, spacecraft and satellites from radiation hazards experienced in space. view more (2005-09-08)
Invasive methods unnecessary for prostate cancer radiation therapy treatment planning
Modern 3-D computed tomography (CT) is an effective method for locating the prostatic apex for radiation therapy treatment planning in prostate cancer patients because it eliminates the need for an invasive procedure and the related side effects. view more (2008-05-21)
Long term risks of medical radiation often ignored
Doctors and patients should be more aware of the long term risks of radiological investigations such as x-rays and CT scans, argues a researcher in this week's BMJ. Use of radiation for medical examinations and tests is the largest manmade source of radiation exposure, yet doctors are insufficiently aware of the long term health risks associated... view more...

Radiation therapy prolongs life in men with recurrent prostate cancer
Men whose tumors recur after prostate cancer surgery are three times more likely to survive their disease long term if they undergo radiotherapy within two years of the recurrence. view more (2008-06-18)
PET scan shows during treatment if radiation is shrinking lung tumor, U-M study shows
Lung cancer patients may not need to wait till their radiation treatment is over to know if it worked. A PET scan several weeks after starting radiation treatment for lung cancer can indicate whether the tumor will respond to the treatment. view more (2007-07-19)
Surviving lung cancer
Countless people have heard the phrase, "You have lung cancer," but only 50 can say they've completed a new treatment at Temple University that doubles their chances of surviving the deadly disease - and without the conventional radiation regimen or surgery. view more (2009-03-05)
Family history of prostate cancer does not affect some treatment outcomes
In a first of its kind study, a first-degree family history of prostate cancer has no impact on the treatment outcomes of prostate cancer patients treated with brachytherapy (also called seed implants), and patients with this type of family history have clinical and pathologic characteristics similar to men with no family history at all, according... view more...

Intravenous gene therapy protects normal tissue of mice during whole-body radiation
Gene therapy administered intravenously could be an effective agent to protect vital organs and tissues from the effects of ionizing radiation in the event of large-scale exposure from a radiological or nuclear bomb. view more (2007-10-29)

Gene therapy administered intravenously could be used as an agent to protect vital organs and tissues from the effects of ionizing radiation in the event of large-scale exposure from a radiological or nuclear bomb. view more (2006-11-08)
Mars Express observes aurorae on the Red Planet
Scientists using ESA's Mars Express have produced the first crude map of aurorae on Mars. These displays of ultraviolet light appear to be located close to the residual magnetic fields generated by Mars's crustal rocks. view more (2008-11-24)
EU Support for Two Projects Coordinated by DESY
The European Commission selected two projects coordinated by the DESY research center in Hamburg for support within its sixth Framework Programme. Among all the competitors for the much-coveted development funds, the projects "EUROFEL" and "EUROTeV" were ranked first and second, respectively, in the referees' evaluation. From... view more...

Rooftop PV data for better energy prediction models
New generations of photovoltaic (PV) roofing products utilize designs that allow them to be integral parts of the roof, providing both electricity and shelter from the elements. view more (2006-06-28)
Complex meteorology at Venus
In its relentless probing of Venus's atmosphere, ESA's Venus Express keeps revealing new details of the Venusian cloud system. Meteorology at Venus is a complex matter, scientists say. view more (2006-10-16)
Fighting tumors with mathematics
To the effective removal of cancerous lesions by hard x-rays a precise radiation plan is indispensable. The malignant growth should be hit with the highest possible dose of radiation while minimizing the dose to the surrounding healthy tissue. The German Cancer Research Center (DKFZ) in Heidelberg is currently developing an improved approach using... view more... (2002-09-09)
Researchers bridge the 'terahertz gap' with new tunable metamaterial
A frequency-agile metamaterial that for the first time can be tuned over a range of frequencies in the so-called "terahertz gap" has been engineered by a team of researchers from Boston College, Los Alamos National Laboratory and Boston University. view more (2008-04-16)
Ozone and UV over Europe: no sign of improvement
"The occurrence of ozone mini-holes over Europe increases and any ozone layer recovery could only become measurable around 2010 at the earliest" concludes an assessment report, released today, on European research in the stratosphere. The report concerns loss of ozone, increases in ultraviolet radiation as well as the impact of aircraft... view more... (2002-01-21)
