People with tinnitus process emotions differently from their peers, researchers report

CHAMPAIGN, Ill. — Patients with persistent ringing in the ears – a condition known as tinnitus – process emotions differently in the brain from those with normal hearing, researchers report in the journal Brain Research.

Tinnitus afflicts 50 million people in the United States, according to the American Tinnitus Association, and causes those with the condition to hear noises that aren't really there. These phantom sounds are not speech, but rather whooshing noises, train whistles, cricket noises or whines. Their severity often varies day to day.

Chronic brain damage not as prevalent in NFL players, say researchers

ROSEMONT, IL – A study published online today in Sports Health: A Multidisciplinary Approach provides a different take on previous information regarding the prevalence of chronic brain damage in retired NFL players.

Neural sweet talk: Taste metaphors emotionally engage the brain

So accustomed are we to metaphors related to taste that when we hear a kind smile described as "sweet," or a resentful comment as "bitter," we most likely don't even think of those words as metaphors. But while it may seem to our ears that "sweet" by any other name means the same thing, new research shows that taste-related words actually engage the emotional centers of the brain more than literal words with the same meaning.

For the next generation: Democracy ensures we don't take it all with us

Given the chance to vote, people will leave behind a legacy of resources that ensures the survival of the next generation, a series of experiments by Yale and Harvard psychologists show. However, when people are left to their own devices, the next generation isn't so lucky.

"People want to do the right thing; they just need a little help from their institutions," said David Rand, assistant professor of psychology at Yale and a co-author of the study appearing June 25 in the journal Nature.

A vote for cooperation

Whatever the solutions to preserving our world's natural resources might be, it seems clear that answers won't come overnight. How, then, can we be sure the steps we take today won't jeopardize the fate of future generations?

The answer, researchers say, may lie with one of cornerstones of modern society – democracy.

Marriage and healthy hearts

PITTSBURGH—The affairs of the heart may actually affect the affairs of the heart in ways previously not understood.

Mathematical models explain how a wrinkle becomes a crease

PROVIDENCE, R.I. [Brown University] — Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, can help make durable circuit boards for flexible electronics.

Collaborative learning -- for robots

Machine learning, in which computers learn new skills by looking for patterns in training data, is the basis of most recent advances in artificial intelligence, from voice-recognition systems to self-parking cars. It's also the technique that autonomous robots typically use to build models of their environments.

Carnegie Mellon method automatically cuts boring parts from long videos

PITTSBURGH—Smartphones, GoPro cameras and Google Glass are making it easy for anyone to shoot video anywhere. But, they do not make it any easier to watch the tedious videos that can result. Carnegie Mellon University computer scientists, however, have invented a video highlighting technique that can automatically pick out the good parts.

Deep brain stimulation improves non motor symptoms in Parkinson's disease

Amsterdam, NL, 25 June 2014 – Deep brain stimulation (DBS) has become a well-recognized non-pharmacologic treatment that improves motor symptoms of patients with early and advanced Parkinson's disease. Evidence now indicates that DBS can decrease the number and severity of non motor symptoms of patients with Parkinson's disease (PD) as well, according to a review published in the Journal of Parkinson's Disease.

3-D computer model may help refine target for deep brain stimulation therapy for dystonia

LOS ANGELES (June 24, 2014) – Although deep brain stimulation can be an effective therapy for dystonia – a potentially crippling movement disorder – the treatment isn't always effective, or benefits may not be immediate. Precise placement of DBS electrodes is one of several factors that can affect results, but few studies have attempted to identify the "sweet spot," where electrode placement yields the best results.

Food ingredient fears

Daily headlines on internet pages and blogs claim: "New ingredient X is harmful to your health." Such warnings can scare people into avoiding these ingredients without actually knowing the facts, leading some people to have food fears about ingredients such as sugar, fat, sodium, high-fructose corn syrup (HFCS), mono sodium glutamate (MSG), and others. While some of these food fears are merited, others can be misleading.

Adults with Asperger Syndrome at significantly higher risk of suicidal thoughts than the general population

Adults with the autism spectrum condition known as Asperger Syndrome are nine times more likely to experience suicidal thoughts than people from the UK general population, according to the first large-scale clinical study of its kind, published in The Lancet Psychiatry.

Engineered bacteria keep mice lean

Obesity levels are rising throughout the world. As obesity rates increase, so do the incidences of diabetes, heart disease, and other serious health conditions. The bacteria within an individual's gut can influence their susceptibility to these disorders. Therefore, altering the microbe population in the gut could prevent or reverse disease. A June 24th study in the Journal of Clinical Investigation demonstrates that modified bacteria can prevent weight gain in mice.

Novel biomarker predicts febrile seizure-related epilepsy, UCI study finds

Irvine, Calif. — A newly discovered biomarker – visible in brain scans for hours after febrile seizures – predicts which individuals will subsequently develop epilepsy, according to UC Irvine researchers. This diagnostic ability could lead to improved use of preventive therapies for the disorder.
