Genetic analysis helps dissect molecular basis of cardiovascular disease
Using highly precise measurements of plasma lipoprotein concentrations determined by nuclear magnetic resonance spectroscopy (NMR), researchers led by Daniel Chasman at Brigham and Women's Hospital and Harvard Medical School in Boston, MA, the Framingham Heart Study in Framingham, and the PROCARDIS consortium in Stockholm, Sweden and Oxford,... view more...

An atomic-level look at an HIV accomplice
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity. view more (2009-11-20)
UCSB physicists move 1 step closer to quantum computing
Physicists at UC Santa Barbara have made an important advance in electrically controlling quantum states of electrons, a step that could help in the development of quantum computing. view more (2009-11-20)
New study confirms exotic electric properties of graphene
First, it was the soccer-ball-shaped molecules dubbed buckyballs. Then it was the cylindrically shaped nanotubes. Now, the hottest new material in physics and nanotechnology is graphene: a remarkably flat molecule made of carbon atoms arranged in hexagonal rings much like molecular chicken wire. view more (2009-11-18)
Novel NIST connector uses magnets for leak-free microfluidic devices
Like other users of microfluidic systems, National Institute of Standards and Technology (NIST) researcher Javier Atencia was faced with an annoying engineering problem: how to simply, reliably and most of all, tightly, connect his tiny devices to the external pumps and reservoirs delivering liquids into the system. view more (2009-11-18)
Fat collections linked to decreased heart function
Researchers from Boston University School of Medicine (BUSM) have shown that fat collection in different body locations, such as around the heart and the aorta and within the liver, are associated with certain decreased heart functions. view more (2009-11-16)
A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all. view more (2009-11-12)
Sweet as can be: how E. coli gets ahead
Scientists at the University of York have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut. view more (2009-11-12)
Neuroimaging provides insights into new treatment options for Alzheimer's disease
With about 35 million people around the world suffering from Alzheimer's disease (AD) by the year 2010 and an expectation that these numbers will double every twenty years with approximately 115 million cases by 2050, pressure on healthcare systems worldwide will be intense. view more (2009-11-11)
'Emotions increase or decrease pain': researchers
Getting a flu shot this fall? Canadians scientists have found that focusing on a pretty image could alleviate the sting of that vaccine. view more (2009-11-11)
New UAB Study Sheds Light on Brain's Response to Distress, Unexpected Events
In a new study, psychologists at the University of Alabama at Birmingham (UAB) are able to see in detail for the first time how various regions of the human brain respond when people experience an unexpected or traumatic event. view more (2009-11-11)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Psychiatric impact of torture could be amplified by head injury
Depression and other emotional symptoms in survivors of torture and other traumatic experiences may be exacerbated by the effects of head injuries, according to a study from the Harvard Program in Refugee Trauma (HPRT), based in the Massachusetts General Hospital (MGH) Department of Psychiatry. view more (2009-11-09)
New TMS clinic offers noninvasive treatment for major depression
Rush University Medical Center has opened the Transcranial Magnetic Stimulation (TMS) Clinic to offer patients suffering from major depression a safe, effective, non-drug treatment. view more (2009-11-06)
Magnetic nanoparticles to simultaneously diagnose, monitor and treat
Whether it's magnetic nanoparticles (mNPs) giving an army of 'therapeutically armed' white blood cells direction to invade a deadly tumour's territory, or the use of mNPs to target specific nerve channels and induce nerve-led behaviour (such as the life-dependant thumping of our hearts), mNPs have come a long way in the past decade. view more (2009-11-06)
Carbon atmosphere discovered on neutron star
Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA's Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object. view more (2009-11-05)
New methods found useful for diagnosing myocarditis
Myocarditis is an important, and often unrecognized cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to a study published in the November 2009 issue of Mayo Clinic Proceedings. view more (2009-11-04)
High-performance plasmas may make reliable, efficient fusion power a reality
In the quest to produce nuclear fusion energy, researchers from the DIII-D National Fusion Facility have recently confirmed long-standing theoretical predictions that performance, efficiency and reliability are simultaneously obtained in tokamaks, the leading magnetic confinement fusion device, operating at their performance limits. view more (2009-11-03)
Precuneus region of human and monkey brain is divided into 4 distinct regions
