Novel Imaging Approach May Assist in Predicting Success of Treatment For Atrial Fibrillation
University of Utah researchers have developed a magnetic resonance imaging (MRI)-based method for detecting and quantifying injury to the wall of the heart's left atrium in patients who have undergone a procedure to treat atrial fibrillation.   view more (2008-10-08)

Portable imaging system will help maximize public health response to natural disasters
Researchers at the Georgia Tech Research Institute (GTRI) have developed a low-cost, high-resolution imaging system that can be attached to a helicopter to create a complete and detailed picture of an area devastated by a hurricane or other natural disaster.   view more (2008-10-07)

Receptor could halt blinding diseases, stop tumor growth, preserve neurons after trauma
An international team of researchers has discovered what promises to be the on-off switch behind several major diseases.   view more (2008-10-07)

New light on link between snoring and cognitive deficits in children
About two-thirds of children with sleep-disordered breathing (SDB)- snoring or obstructive sleep apnea (OSA)- have some degree of cognitive deficit, but the severity of the cognitive deficit has been notoriously difficult to correlate to the severity of the SDB.   view more (2008-10-07)

Food for thought -- regulating energy supply to the brain during fasting
If the current financial climate has taught us anything, it's that a system where over-borrowing goes unchecked eventually ends in disaster. It turns out this rule applies as much to our bodies as it does to economics. Instead of cash, our body deals in energy borrowed from muscle and given to the... view more (2008-10-06)

New screening technologies improve detection of polyps during colonoscopy
Two studies presented at the American College of Gastroenterology's 73rd Annual Scientific Meeting in Orlando highlight new technologies with the potential to improve the detection of colorectal polyps and flat lesions during colonoscopy.   view more (2008-10-06)

6 environmental research studies reveal critical health risks from plastic
Exposure to Bisphenol A (BPA), phthalates and flame retardants (PBDEs) are strongly associated with adverse health effects on humans and laboratory animals.   view more (2008-10-03)

Millisecond brain signals predict response to fast-acting antidepressant
Images of the brain's fastest signals reveal an electromagnetic marker that predicts a patient's response to a fast-acting antidepressant, researchers have discovered.   view more (2008-10-03)

Musicians use both sides of their brains more frequently than average people
Supporting what many of us who are not musically talented have often felt, new research reveals that trained musicians really do think differently than the rest of us.   view more (2008-10-03)

Singing to females makes male birds' brains happy
The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer.   view more (2008-10-03)

Zooming way in, technique offers close-ups of electrons, nuclei
Providing a glimpse into the infinitesimal, physicists have found a novel way of spying on some of the universe's tiniest building blocks.   view more (2008-10-02)

Structures of Important Plant Viruses Determined
Flexible filamentous viruses make up a large fraction of known plant viruses and are responsible for more than half the viral damage to crop plants throughout the world.   view more (2008-10-02)

Treatment window expanded
Patients can still benefit up to 4.5 hours after a stroke if a drug that dis-solves blood clots in the brain is administered. Thus far, three hours had been considered the useful limit for administering thrombolytic drugs.   view more (2008-10-01)

During exercise, the human brain shifts into high gear on 'alternative energy'
Alternative energy is all the rage in major media headlines, but for the human brain, this is old news. According to a study by researchers from Denmark and The Netherlands published in the October 2008 print issue of The FASEB Journal, the brain, just like muscles, works harder during strenuous... view more (2008-10-01)

Direct recording shows brain signal persists even in dreamless sleep
Neuroscientists at Washington University School of Medicine in St. Louis have taken one of the first direct looks at one of the human brain's most fundamental "foundations": a brain signal that never switches off and may support many cognitive functions.   view more (2008-10-01)

MRI spots DCIS in mice
A new magnetic resonance imaging procedure can detect very early breast cancer in mice, including ductal carcinoma in situ (DCIS), a precursor to invasive cancer. Some of the tumors detected were less than 300 microns in diameter, the smallest cancers ever detected by MRI.   view more (2008-10-01)

Smoking increases depression in women, study reveals
Researchers from the University of Melbourne and Barwon Health assessed a group of 1043 Australian women, whose health had been monitored for a decade as part of the Geelong Osteoporosis Study.   view more (2008-10-01)

Learning to shape your brain activity
A study in the Oct. 1 issue of the journal Sleep shows that the successful manipulation of sensorimotor rhythm (SMR) amplitude by instrumental SMR conditioning (ISC) improved sleep quality as well as declarative learning. ISC might thus be considered a promising non-pharmacological treatment for... view more (2008-10-01)

Adolescent insomnia linked to depression and substance abuse during adolescence and young adulthood
A study in the Oct. 1 issue of the journal Sleep shows that adolescent insomnia symptoms are associated with depression, suicide ideation and attempts, and the use of alcohol, cannabis and other drugs such as cocaine.   view more (2008-10-01)

Blood thinning drug linked to increased bleeding in brain
A new study shows that people who take the commonly used blood thinning drug warfarin may have larger amounts of bleeding in the brain and increased risk of death if they suffer a hemorrhagic stroke.   view more (2008-09-30)

Is there more to prion protein than mad cow disease?
Prion protein, a form of protein that triggers BSE, is associated with other brain diseases in cattle, raising the possibility of a significant increase in the range of prion disease.   view more (2008-09-30)

Groundbreaking findings on autism to be presented at Carnegie Mellon international symposium
Today's autism research draws on a variety of scientific disciplines, from genetics to functional magnetic resonance imaging (fMRI) to neural development. At the 35th Carnegie Symposium on Cognition, "Development and Brain Systems in Autism," 16 of the world's most prominent autism... view more (2008-09-30)

Do 'light' cigarettes deliver less nicotine to the brain than regular cigarettes?
For decades now, cigarette makers have marketed so-called light cigarettes - which contain less nicotine than regular smokes - with the implication that they are less harmful to smokers' health. A new UCLA study shows, however, that they deliver nearly as much nicotine to the brain.   view more (2008-09-29)

'Hub' of fear memory formation identified in brain cells
A protein required for the earliest steps in embryonic development also plays a key role in solidifying fear memories in the brains of adult animals, scientists have revealed. An apparent "hub" for changes in the connections between brain cells, beta-catenin could be a potential target... view more (2008-09-29)

New approach to gene therapy may shrink brain tumors, prevent their spread
Massachusetts General Hospital (MGH) researchers are investigating a new approach to gene therapy for brain tumors - delivering a cancer-fighting gene to normal brain tissue around the tumor to keep it from spreading.   view more (2008-09-26)
