A Neural Mosaic of Tones
The brain filters what we hear. It can do this in part because particular groups of neurons react to specific frequencies of sound. view more (2006-06-23)
Researchers use mass spectrometry to detect norovirus particles
Scientists have used mass spectrometry for decades to determine the chemical composition of samples but rarely has it been used to identify viruses, and never in complex environmental samples. view more (2006-04-07)
From biological imaging to Sudoku solutions
Cornell physicist Veit Elser has been engrossed recently in resolving a pivotal question in biological imaging. So he hasn't had much time for brainteasers and number games. view more (2006-03-06)
Finding out which parts of the brain do what
Ever since the Greeks proposed that different parts of the brain housed different parts of the ‘soul’, mankind has tried to discover where our mental functions are located. This evening, Thursday 22 February, in a public lecture at the Royal Society, 6 Carlton House Terrace, London SW1Y 5AG, Professor Alan Cowey FRS of the University... view more... (2001-02-15)
Long the Fixation of Physicists Worldwide, a Tiny Particle Is Found
After decades of intensive effort by both experimental and theoretical physicists worldwide, a tiny particle with no charge, a very low mass and a lifetime much shorter than a nanosecond, dubbed the "axion," has now been detected by the University at Buffalo physicist who first suggested its existence in a little-read paper as early as... view more...

Obesity research boosted by watching hunger in the brain
Scientists can now measure how full or hungry a mouse feels, thanks to a new technique which uses imaging to reveal how neurons behave in the part of the brain which regulates appetite. view more (2007-11-08)
Big magnet ready to face the big questions of the universe
The largest superconducting magnet ever built has successfully been powered up to its operating conditions at the first attempt. Called the Barrel Toroid because of its shape, this magnet is a vital part of ATLAS, one of the major particle detectors being prepared to take data at CERN's Large Hadron Collider (LHC), the new particle accelerator... view more...

Early myocardial enhancement defects on multidetector CT predicts future myocardial viability
Early myocardial enhancement defects (dark spots) on multidetector CT are valuable predictors of myocardial viability in patients who have suffered a heart attack. view more (2006-05-03)
Study points to possibility of blood test to detect lung cancer
A test for four blood proteins may provide a less-invasive follow-up for patients who have suspicious lesions on chest radiographs or computerized tomography (CT) scans, according to a new study led by Duke University Medical Center researchers. view more (2007-12-10)
Cassini finds Prometheus a sculptor of Saturn's rings
New findings from members of the Cassini imaging team show that certain prominent features in Saturn's narrow and contorted F ring can be understood in terms of a simple gravitational interaction with the small moon Prometheus. view more (2005-10-27)
3-D fruit fly images to benefit brain research
The fragile head and brain of a fly are not easy things to examine but MRC scientists have figured out how to make it a little simpler. And they hope their research will shed light on human disease. view more (2007-09-05)
Chronic back pain linked to changes in the brain
A German research team using a specialized imaging technique revealed that individuals suffering from chronic low back pain also had microstructural changes in their brains. view more (2006-11-29)
Optical imaging added to ultrasound improves breast cancer diagnosis
A new study shows that combining a technology called optical tomography with standard ultrasound imaging can help distinguish early-stage breast cancer from non-cancerous lesions-and potentially reduce the number of breast biopsies performed. view more (2005-09-27)
New technique developed for tracking cells in the body
Scientists' inability to follow the whereabouts of cells injected into the human body has long been a major drawback in developing effective medical therapies. view more (2007-03-21)
New technology useful for soft-tissue imaging in interventional radiology procedures
Soft-tissue cross-sectional imaging acquired on a flat panel C-arm fluoroscopic unit located in the interventional radiology area is feasible and useful for interventional radiology procedures, avoiding the necessity of sending patients out to a CT scanner. view more (2007-05-07)
MDCT Arthrography Good for Assessing Hip Dysplasia
MDCT arthrography is an accurate method for assessing cartilage loss in patients with hip dysplasia and may be more reliable than MRI in such instances. view more (2005-08-08)
U-M researchers use nanoparticles to target brain cancer
Tiny particles one-billionth of a meter in size can be loaded with high concentrations of drugs designed to kill brain cancer. view more (2006-11-15)
Cassini finds more rings highlighted by telltale small particles
Images taken by NASA's Cassini spacecraft, looking in the direction of the Sun, have provided scientists fresh insights into the dynamic nature of the rings and, in particular, the creation of new rings made from tiny particles released from larger bodies. view more (2006-10-12)
Are teenage brains really different?
Many parents are convinced that the brains of their teenage offspring are different than those of children and adults. view more (2008-03-31)
Aching back? Sitting up straight could be the culprit
Researchers are using a new form of magnetic resonance imaging (MRI) to show that sitting in an upright position places unnecessary strain on your back, leading to potentially chronic pain problems if you spend long hours sitting. view more (2006-11-28)
