Towards a better screen

Harvard University researchers have designed more than 1,000 new blue-light emitting molecules for organic light-emitting diodes (OLEDs) that could dramatically improve displays for televisions, phones, tablets and more.

Alzheimer fibrils at atomic resolution

Alzheimer fibrils at atomic resolution

FRANKFURT. Elongated fibres (fibrils) of the beta-amyloid protein form the typical senile plaques present in the brains of patients with Alzheimer's disease. A European research team and a team from the United States (Massachussetts Institute of Technology in cooperation with Lund University) have simultaneously succeeded in elucidating the structure of the most disease-relevant beta-amyloid peptide 1-42 fibrils at atomic resolution. This simplifies the targeted search for drugs to treat Alzheimer's dementia.

Targeting brain cells to alleviate neuropathic pain

Neuropathic pain - which affects more than 1 million Americans - could be reduced or even eliminated by targeting brain cells that are supposed to provide immunity but, in some instances, do the opposite, causing chronic pain that could last a lifetime.

College students who misuse stimulants more likely to have ADHD, substance-use disorder

A new study by Massachusetts General Hospital (MGH) investigators finds that college students who misuse stimulant drugs are more likely to have attention-deficit hyperactivity disorder (ADHD), conduct disorder or substance-use disorder than are students not misusing stimulants. The report published in the Journal of Clinical Psychiatry also finds immediate-release stimulants are more likely to be misused than extended-release versions of the drugs.

Study finds brain connections key to reading

A new study from MIT reveals that a brain region dedicated to reading has connections for that skill even before children learn to read.

By scanning the brains of children before and after they learned to read, the researchers found that they could predict the precise location where each child's visual word form area (VWFA) would develop, based on the connections of that region to other parts of the brain.

Negative attention from teachers can lead to more negative student behaviors

COLUMBIA, Mo. - Previous research has found that student-teacher interactions during the school day are important factors in behavioral and academic outcomes for the students. Now, researchers at the University of Missouri College of Education have developed a new method for observing and measuring teacher interaction with every child in a classroom.

New model recreates early spread of Parkinson's disease in the brain

GRAND RAPIDS, Mich. (Aug. 8, 2016)--They're two of the biggest mysteries in Parkinson's disease research--where does the disease start? And how can it be stopped early in the process?

Human brain recordings provide highly sought insights into cause of Parkinson's disease

Researchers at Yerkes National Primate Research Center, Emory University, are the first to systematically record neural activity in the human striatum, a deep brain structure that plays a major role in cognitive and motor function. These two functions are compromised in Parkinson's disease (PD), which makes the neuron-firing abnormalities the study results revealed key to better understanding the pathophysiology of PD and, ultimately, developing better treatments and preventions.

After the fight, friendship

It's not exactly front-page news that when it comes to conflict, men and women are very different.

The way they resolve those conflicts, though, is another story.

While men are often portrayed as aggressive and combative, a new study shows that, from the tennis court to the boxing ring -- the modern-day equivalent of one-on-one conflict -- men are more likely than women to make peace with their competitors after the final whistle blows.

Therapeutic strategies targeting Alzheimer's disease-related molecules

Therapeutic strategies targeting Alzheimer's disease (AD)-related molecule β-amyloid (Aβ), Tau protein and BACE enzyme have been recently explored. However?the therapeutic efficacy for a single target is not ideal. The clinical trials that clean Aβ from the brain in AD patients were largely unsuccessful. It is well known that the inflammatory response is one component of AD pathogenesis, leading to a series of irreversible pathological events.
