New findings show that multiple efforts designed to improve memory skills similarly improve fluid intelligence.

Brain-training efforts designed to improve working memory can also boost scores in general problem-solving ability and improve fluid intelligence, according to new University of Michigan research.

Comment: And SoTT is here to assist that all important Brain Training folks!

Study offers novel insight into cardiac arrhythmias, sudden cardiac death

A new study by researchers at Rhode Island Hospital provides much-needed insight into the molecular mechanisms that cause arrythmia, or irregular heartbeat, and how it triggers sudden cardiac death, one of the nation's leading killers. Their findings, published online in the Journal of Clinical Investigation, could pave the way for the development of new, genetically-targeted therapies to treat and prevent fatal arrythmias.

Most cases of sudden cardiac death are related to arrhythmias, including clinical conditions such as long QT syndrome (LQTS), a disorder of the heart's electrical system that causes fast, chaotic heartbeats. LQTS - which can be inherited or brought on by certain medications - usually affects otherwise healthy children and young adults. Although LQTS seems to be relatively rare, experts believe it is also underdiagnosed, meaning variants of it may be more common than previously suspected.

Justice in the brain: Equity and efficiency are encoded differently

Which is better, giving more food to a few hungry people or letting some food go to waste so that everyone gets a share" A study appearing this week in Science finds that most people choose the latter, and that the brain responds in unique ways to inefficiency and inequity.

The study, by researchers at the University of Illinois and the California Institute of Technology, used functional magnetic resonance imaging (fMRI) to scan the brains of people making a series of tough decisions about how to allocate donations to children in a Ugandan orphanage.

The researchers hoped to shed light on the neurological underpinnings of moral decision-making, said co-principal investigator Ming Hsu, a fellow at the U. of I.'s Beckman Institute for Advanced Science and Technology.

"Morality is a question of broad interest," Hsu said. "What makes us moral, and how do we make tradeoffs in difficult situations""

Study finds link between birth order and asthma symptoms

Among four year-olds attending Head Start programs in New York City, those who had older siblings were more likely to experience respiratory symptoms including an episode of wheezing in the past year than those who were oldest or only children. Children with at least two older siblings were also 50% more likely than other children to have gone to an emergency department or been hospitalized overnight for breathing problems. These findings from the Columbia University Mailman School of Public Health were recently pre-published online in the journal Clinical and Experimental Allergy.

"Our findings support the hypothesis that having older siblings increases a child's risk of exposure to infectious agents before age two years, and in turn increases the child's risk for wheezing," said Matthew Perzanowski, PhD, assistant professor of Environmental Health Sciences at the Mailman School of Public Health and the lead author of the paper. "Some studies have found that having older siblings increases the risk of wheeze in babies and toddlers. Our findings are novel in that we found that among the four year-olds in this study, the pattern was the same as has been observed in younger children elsewhere."

Calm The Heart To Stop A Stroke?

There's an electrical storm brewing inside the hearts of more than 2.2 million Americans. And just like lightning, this kind of storm can have devastating consequences.

What happens when medicines aren't enough, and fail to control clotting and rhythm? And what about AF patients who have other problems that keep them from being able to take certain medicines? That's when procedures offered by a few specialized centers, including U-M, might be an option.

The "storm", in this case, is a condition called atrial fibrillation - the most common form of irregular heartbeat in the United States.

And the "lightning bolts" they can produce are tiny blood clots, which can form when blood pools in a heart that's not beating regularly. When these clots escape the heart, they can travel to the brain. And then, quick as lightning, those clots can cause a stroke or mini-stroke that can kill or disable a person within minutes.
