EU research drive to reduce air pollution from traffic
Today the EU signed an agreement with the USA, Japan and China to address air pollution from transport. Signed during a conference in Milan, the accord will allow for joint research on emissions and vehicle testing, and it foresees the creation of a common scientific platform to measure and benchmark air pollution from traffic. The joint effort... view more... (2003-12-10)
Fusing imaging technologies creates 'synergy,' helps diagnose heart disease accurately
To fight heart disease, you have to get to the "heart of the problem" by diagnosing it more accurately. Researchers did just that, releasing their findings at SNM's 54th Annual Meeting June 2-6 in Washington, D.C. SNM is the world's largest society for molecular imaging and nuclear medicine professionals. view more (2007-06-04)
PET Imaging Shows Young Smokers Quick Benefit of Quitting
The early stages of coronary artery disease in young smokers can be reversed quickly if they choose to put out their cigarettes for good, according to a positron emission tomography (PET) imaging study in the December Journal of Nuclear Medicine. view more (2006-12-06)
Theorists Reveal Path to True Muonium
True muonium, a long-theorized but never-seen atom, might be observed in future experiments, thanks to recent theoretical work by researchers at the Department of Energy's SLAC National Accelerator Laboratory and Arizona State University. view more (2009-06-01)
Quantum Leap in Diagnosis of Disease
A state-of-the-art diagnosis system is now being introduced at the University of Bonn's Radiological Clinic: the first of its kind worldwide, it is a new type of high-field nuclear magnetic resonance tomography spectrometer which opens up completely new possibilities both for clinical application to patients, for clinical research and pure... view more...

Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication. view more (2008-02-20)
Computer model helps combat air pollution across Europe
The key role of multidisciplinary research in developing a landmark intergovernmental strategy to combat air pollution across Europe will be considered by Professor Helen ApSimon of Imperial College London in her inaugural lecture, A lot of Hot Air - Transboundary Air Pollution Over Europe. view more (2003-01-28)
Journal Studies Find Relationship Between Delirium, Dementia
Dementia, including Alzheimer's disease, is one of the most devastating conditions of older age. Currently affecting nearly 7 million individuals in the U.S. and 24 million worldwide, dementia leads to total loss of memory and the ability to function independently-making it one of people's greatest fears of aging. view more (2007-01-18)
Brain surgery, new light-emitting materials and medical imaging - all are covered in the December issue of Opto and Laser Europe
LASERS ON THE BRAIN A new, minimally-invasive tool that can completely remove a brain tumour through a small hole in the skull has been delivered to surgeons in Germany. Conventional techniques use lasers to destroy brain tumours by thermal effects. This can destroy healthy tissue, and increases the risk of toxic side effects because it does not... view more...

Brain region central to placebo effect identified
Researchers have pinpointed a brain region central to the machinery of the placebo effect-the often controversial phenomenon in which a person's belief in the efficacy of a treatment such as a painkilling drug influences its effect. view more (2007-07-19)
CT angiography highly accurate, multicenter trials show
Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2007-11-27)
Evidence for ultra-energetic particles in jet from black hole
An international team of astronomers led by researchers at Yale has obtained key infrared observations that reveal the nature of quasar particle jets that originate just outside super-massive black holes at the center of galaxies and radiate across the spectrum from radio to X-ray wavelengths. view more (2006-06-21)
New research explores limits of non-invasive coronary imaging tests
If multi-slice computed tomography (MSCT) shows that a patient has plaque build-up in the artery walls, does it also mean that there is actual reduced blood flow in the artery\\\ view more (2006-12-12)
Red sky at night -- astronomers delight
A collaboration of over 50 astronomers, The IPHAS consortium, led from the UK, with partners in Europe, USA, Australia, has released the first comprehensive optical digital survey of our own Milky Way. view more (2007-12-11)

NCRP Report No. 160 on increased average radiation exposure of the US population
Scientists at the American Association of Physicists in Medicine (AAPM) are offering additional background information to help the public avoid misinterpreting the findings contained in a report issued today by the National Council on Radiation Protection and Measurements (NCRP), a non-profit body chartered by the U.S. Congress to make... view more...

Thousands of cold anti-atoms produced at CERN
An international team of physicists working at the Antiproton Decelerator (AD) facility at CERN has announced the first controlled production of large numbers of antihydrogen atoms at low energies. After mixing cold clouds of trapped positrons and antiprotons - the antiparticles of the familiar electron and proton - under closely monitored... view more... (2002-09-18)
Specific regions of brain implicated in anorexia nervosa, finds Univ. of Pittsburgh study
Just why those with anorexia nervosa are driven to be excessively thin and seem unaware of the seriousness of their condition could be due to over-activity of a chemical system found in a region deep inside the brain, a University of Pittsburgh study suggests. view more (2005-07-07)
Neuroscientists searching for roots of empathy
In a pair of pioneering studies, a French (INSERM) and American team of social-cognitive neuroscientists have identified a network of brain regions that are involved in human imitation and specific brain areas that enable a person to distinguish the self from others. The research is part of a larger effort to find the neurological basis of social... view more... (2002-01-23)
Study Shows Promising Results in Deep Brain Stimulation for Treatment-Resistant Depression
New data from a study of patients with treatment-resistant depression who underwent deep brain stimulation (DBS) in the subcallosal cingulate region (SCG or Cg25) of the brain shows that this intervention is generally safe and provides significant improvement in patients as early as one month after treatment. The patients also experienced... view more... (2008-07-22)
