Vanderbilt researchers find that diabetes drug could be effective in treating addiction

Vanderbilt researchers are reporting today that a drug currently used to treat type 2 diabetes could be just as effective in treating addiction to drugs, including cocaine.

The findings, published online today as a Letter To The Editor in the journal Molecular Psychiatry, could have far-reaching implications for patients worldwide who suffer from addiction.

A circuit diagram of the mouse brain

What happens in the brain when we see, hear, think and remember? To be able to answer questions like this, neuroscientists need information about how the millions of neurons in the brain are connected to each other. Scientists at the Max Planck Institute for Medical Research in Heidelberg have taken a crucial step towards obtaining a complete circuit diagram of the brain of the mouse, a key model organism for the neurosciences. The research group working with Winfried Denk has developed a method for preparing the whole mouse brain for a special microscopy process.

Study shows New Jersey's decal for young drivers reduced crashes

Philadelphia, October 23—A new study shows that New Jersey's law requiring novice drivers to display a red decal on their license plates has prevented more than 1,600 crashes and helped police officers enforce regulations unique to new drivers. The first-in-the-nation decal provision went into effect in May 2010 as part of N.J.'s Graduated Driver Licensing (GDL) law. Nearly every state has a GDL law on the books, but "Kyleigh's Law," named for a teen driver killed in a 2006 N.J.

Wayne State researcher's take on brain chemical analysis featured

Detroit - A Wayne State University researcher's take on the current state of brain chemical analysis is the cover story in a recent professional journal, accompanied by a podcast.

ONR to dial up faster data for the Marines

ARLINGTON, Va. - Office of Naval Research (ONR) officials announced a new program Oct. 22 to optimize tactical handheld technology for quick decision-making in the field.

The Exchange of Actionable Information at the Tactical Edge (EAITE) program, designed to sift through data from multiple sources for faster analysis, is among more than a dozen Future Naval Capability (FNC) programs kicking off in fiscal year 2014.

Exercise the body to keep the brain healthy, study suggests

People who exercise later in life may better protect their brain from age-related changes than those who do not, a study suggests.

Researchers found that people over 70 who took regular exercise showed less brain shrinkage over a three-year period than those who did little exercise.

Psychologists and Neuroimaging experts, based at the University of Edinburgh, did not find there to be any benefit to brain health for older people from participation in social or mentally stimulating activities.

Aggressive brain tumors can originate from a range of nervous system cells

LA JOLLA, CA---- Scientists have long believed that glioblastoma multiforme (GBM), the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. In a paper published October 17 in Science, however, researchers at the Salk Institute for Biological Studies have found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.

Parenting and temperament in childhood predict later political ideology

Political mindsets are the product of an individual's upbringing, life experiences, and environment. But are there specific experiences that lead a person to choose one political ideology over another?

New research from psychological scientist R. Chris Fraley of the University of Illinois at Urbana-Champaign and colleagues suggest that parenting practices and childhood temperament may play an influential role. Their study is published online in Psychological Science, a journal of the Association for Psychological Science.

Clue to cause of Alzheimer's dementia found in brain samples

Researchers at Washington University School of Medicine in St. Louis have found a key difference in the brains of people with Alzheimer's disease and those who are cognitively normal but still have brain plaques that characterize this type of dementia.

Fewer patient deaths after surgery in hospitals known for good nursing care

Patients treated in magnet hospitals (specially designated for their nursing excellence) had 14 percent lower odds of death than those in non-magnet hospitals in a four-state study of 564 hospitals led by the University of Pennsylvania School of Nursing. The magnet designation, determined by the American Nurses Credentialing Center, recognizes high-quality patient care, high levels of nurse education, and nursing innovation.

Can your body sense future events without any external clue?

EVANSTON, Ill. --- Wouldn't it be amazing if our bodies prepared us for future events that could be very important to us, even if there's no clue about what those events will be?

Presentiment without any external clues may, in fact, exist, according to new Northwestern University research that analyzes the results of 26 studies published between 1978 and 2010.

A whale with a distinctly human-like voice

For the first time, researchers have been able to show by acoustic analysis that whales—or at least one very special white whale—can imitate the voices of humans. That's a surprise, because whales typically produce sounds in a manner that is wholly different from humans, say researchers who report their findings in the October 23 issue of Current Biology, a Cell Press publication.

CAMH protein discovery may lead to new treatment to prevent smoking relapse

For Immediate Release – October 22, 2012 (Toronto) – Scientists at the Centre for Addiction and Mental Health (CAMH) have identified a potential new approach to preventing smoking relapse, which occurs frequently in smokers who attempt to quit, despite current treatments.

"We have developed a protein peptide that may be a new type of highly targeted treatment to prevent smoking relapse," says Dr. Fang Liu, Senior Scientist in CAMH's Campbell Family Mental Health Research Institute and Professor in the Department of Psychiatry at the University of Toronto.

Survival of the shyest?

A fish's personality can influence how it responds to, and learns from threats, according to a new study by Professor Grant Brown from Concordia University in Canada and his colleagues. Their work, looking at how personality influences a fish's memory of a predator threat, shows that bold trout forget predator odor, and hence potentially predator threat, quicker than shy trout. The research is published online in Springer's journal Behavioral Ecology and Sociobiology.

Aspirin may slow the decline in mental capacity among elderly patients

A daily dose of acetylsalicylic acid equivalent to a fourth of an aspirin may slow the decline in intellectual capacity among elderly individuals with high cardiovascular risk.This is shown in a study by Sahlgrenska Academy, University of Gothenburg, Sweden.

Researchers at Sahlgrenska Academy, University of Gothenburg, over a five year period studied how intellectual capacity changes among 681 elderly women (70 to 92 years) with heightened risk of suffering from a heart attack, vascular spasm or stroke.
