Sensing the infrared: Researchers improve IR detectors with single-walled carbon nanotubes
Whether used in telescopes or optoelectronic communications, infrared detectors must be continuously cooled to avoid being overwhelmed by stray thermal radiation. View More (2012-05-24)
Novel biomarkers reveal evidence of radiation exposure
Researchers at the Medical College of Wisconsin have identified novel biomarkers that could be used to confirm exposure to damaging radiation in large groups of people potentially exposed to unknown and variable doses for the purpose of triage and treatment. View More (2012-05-23)
Performance boost for microchips
The semiconductor industry is faced with the challenge of supplying ever faster and more powerful chips. The Next-Generation Lithography with EUV radiation will help meeting that challenge. Fraunhofer researchers have developed key components. View More (2012-05-21)
Statins prevent cancer in heart transplant recipients
Statins prevent cancer and reduce death from all causes in heart transplant recipients. The findings were independent of cholesterol levels. View More (2012-05-21)
Relief of urinary symptoms is an underappreciated benefit of early stage prostate cancer treatment
Treatment of early stage prostate cancer can also result in improved quality of life for a subgroup of men who suffer from lower urinary tract symptoms (LUTS), according to an abstract of a Beth Israel Deaconess Medical Center-led study presented to the American Urological Association.

Revised glioblastoma classification should improve patient care
Radiation oncology researchers have revised the system used by doctors since the 1990s to determine the prognosis of people with glioblastoma, which is the most devastating of malignant brain tumors. View More (2012-05-17)
Electronic medical record tool cuts down on unnecessary CT scans in ER patients with abdominal pain
A new electronic medical record tool that tallies patients' previous radiation exposure from CT scans helps reduce potentially unnecessary use of the tests among emergency room patients with abdominal pain. View More (2012-05-14)
Breathing during radiotherapy - how to hit the treatment target without causing collateral damage
Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumour, or a potentially toxic over-dose to the surrounding healthy tissue. View More (2012-05-14)
Study shows benefit of new maintenance therapy for multiple myeloma
Multiple myeloma is a form of cancer where the plasma cells in the bone marrow grow out of control, causing damage to bones as well as predisposing patients to anemia, infection and kidney failure. View More (2012-05-14)
Researchers discover how to overcome poor response to radiotherapy caused by low haemoglobin levels
Patients with head and neck cancer and a low haemoglobin (Hb) level do not respond well to radiotherapy and therefore both control of their tumour and disease-free survival are compromised. View More (2012-05-11)
Highly targeted irradiation as good as whole breast radiotherapy in early stage cancer
Using a concentrated, highly targeted dose of radiation to the breast has equally good results as irradiating the whole area, with no adverse effects on survival and a much better cosmetic outcome, Hungarian researchers have found. View More (2012-05-11)
EARTH: Volcanoes sparked, and prolonged, the Little Ice Age
olcanism is often implicated in periods of abrupt cooling. After the 1991 eruption of Mount Pinatubo in the Philippines, for instance, global temperatures dropped by half a degree Celsius due to airborne particulate matter blocking solar radiation. View More (2012-05-10)
3-D image guided brachytherapy helps avoid hysterectomies for cervical cancer patients
Delivering radiotherapy directly to cancer of the cervix using 3-D imaging techniques is effective at controlling the return and spread of the disease and, in most cases, avoids the need for hysterectomies. View More (2012-05-10)
Staging and Risk Stratification of Thyroid Cancer Improved with SPECT/CT
The use of single positron emission computed tomography (SPECT)/computed tomography (CT) has been reported to change clinical management in a significant number of thyroid cancer patients according to research presented in the May issue of The Journal of Nuclear Medicine. View More (2012-05-04)
Low-dose whole-body CT finds disease missed on standard imaging for patients with multiple myeloma
Low dose whole body CT is nearly four times better than radiographic skeletal survey, the standard of care in the U.S., for determining the extent of disease in patients with multiple myeloma, a new study shows. View More (2012-05-03)
Cone beam CT proves better for visualizing some causes of hearing loss at half the radiation dose
Cone beam CT is superior to mutidetector CT for detecting superior semicircular canal dehiscence or the so called third window (a small hole in the bony wall of the inner ear bone that can cause dizziness and hearing loss) and it uses half the radiation dose, a new study shows.

Digital breast tomosynthesis cuts recall rates by 40 percent
Adding digital breast tomosynthesis to 2D mammography screening results in a 40% reduction in patient recall rates compared to routine screening mammography alone, a new study shows. View More (2012-05-03)
Simple assault and ground level fall do not require cervical spine CT
Cervical spine CT examinations are unnecessary for emergency department (ED) patients who are a victim of "simple assault" or who have a "ground-level fall", unless the patient has a condition that predisposes the patient to spine fracture, a new study finds. View More (2012-05-03)
Experts write on the risks of low-level radiation
Each time a release of radioactivity occurs, questions arise and debates unfold on the health risks at low doses-and still, just over a year after the disaster at the Fukushima Nuclear Power Station, unanswered questions and unsettled debates remain. View More (2012-05-02)
First-of-its-kind 'Menopause Map' helps women navigate treatment
