New hardware boosts communication speed on multi-core chips

Computer engineers at North Carolina State University have developed hardware that allows programs to operate more efficiently by significantly boosting the speed at which the "cores" on a computer chip communicate with each other.

More than allergies: Histamine may be a possible drug target for multiple sclerosis

If you think histamines are your nemesis during allergy season, here's something that might change your perspective. New research published in the Journal of Leukocyte Biology (http://www.jleukbio.org) shows that histamine could be an important molecule to developing new treatments for multiple sclerosis (MS). In the study, the scientists analyzed the role of histamine in an animal model of multiple sclerosis and found that histamine plays a critical role in preventing MS or lessening its effects.

Revealing the wiring that allows us to adapt to the unexpected

Milan, Italy, 31 January 2010 – Wouldn't life be easy if everything happened as we anticipated? In reality, our brains are able to adapt to the unexpected using an inbuilt network that makes predictions about the world and monitors how those predictions turn out. An area at the front of the brain, called the orbitofrontal cortex, plays a central role and studies have shown that patients with damage to this area confuse memories with reality and continue to anticipate events that are no longer likely to happen.

The changing roles of 2 hemispheres in stroke recovery

Milan, Italy, 31 January 2010 – Most people who survive a stroke recover some degree of their motor, sensory and cognitive functions over the following months and years. This recovery is commonly believed to reflect a reorganisation of the central nervous system that occurs after brain damage. Now a new study, published in the February 2011 issue of Elsevier's Cortex, sheds further light on the recovery process through its effect on language skills.

Scripps Research scientists reveal key mechanism governing nicotine addiction

JUPITER, FL – January 25, 2011 – Embargoed by the journal Nature until January 30, 1 PM Eastern time – Scientists from the Florida campus of The Scripps Research Institute have identified a pathway in the brain that regulates an individual's vulnerability to the addictive properties of nicotine. The findings suggest a new target for anti-smoking therapies.

The study appeared January 30, 2011, in an advance, online issue of the journal Nature.

A deficiency of dietary omega-3 may explain depressive behaviors

How maternal essential fatty acid deficiency impact on its progeny is poorly understood. Dietary insufficiency in omega-3 fatty acid has been implicated in many disorders. Researchers from Inserm and INRA and their collaborators in Spain collaboration, have studied mice fed on a diet low in omega-3 fatty acid. They discovered that reduced levels of omega-3 had deleterious consequences on synaptic functions and emotional behaviours.

Surf's up: New research provides precise way to monitor ocean wave behavior, shore impacts

CORVALLIS, Ore. – Engineers have created a new type of "stereo vision" to use in studying ocean waves as they pound against the shore, providing a better way to understand and monitor this violent, ever-changing environment.

The approach, which uses two video cameras to feed data into an advanced computer system, can observe large areas of ocean waves in real time and help explain what they are doing and why, scientists say.

Study finds presence of peers heightens teens' sensitivity to rewards of a risk

It is well known that teenagers take risks — and that when they do, they like to have company. Teens are five times more likely to be in a car accident when in a group than when driving alone, and they are more likely to commit a crime in a group.

Now, a new study sheds light on why.

Helping others helps alcoholics stay on the road to recovery, Case Western Reserve shows

Participating in community service activities and helping others is not just good for the soul; it has a healing effect that helps alcoholics and other addicts become and stay sober, a researcher from Case Western Reserve University School of Medicine reports.

Mini-strokes leave 'hidden' brain damage: Vancouver Coastal Health and UBC Research

Each year, approximately 150,000 Canadians have a transient ischemic attack (TIA), sometimes known as a mini-stroke. New research published today in Stroke, the journal of the American Heart Association shows these attacks may not be transient at all. They in fact create lasting damage to the brain.

Retired NFL players misuse painkillers more than general population

Retired NFL players misuse painkillers more than general population

Those who misused the drugs during their playing days were more likely to continue misusing them after retiring from football. Some 15 percent of those who misused the drugs as active players still were misusing them in retirement. Only 5 percent of former players who took the drugs as prescribed misused them after they retired from the NFL.

Infants ascribe social dominance to larger individuals

CAMBRIDGE, Mass. -- Psychologists at Harvard University have found that infants less than one year old understand social dominance and use relative size to predict who will prevail when two individuals' goals conflict. The finding is presented this week in the journal Science.
