New designer drug, 'bath salts,' may confer additional risk for adolescents

BOSTON — Use and abuse of "bath salts," a new group of designer drugs, have been increasing in recent years, particularly among teenagers. Poison control centers received over 2,000 calls last year for patients with delusions, hallucinations and paranoia following "bath salt" use.

Saint Louis University, University of Toronto biologists help decode turtle genome

ST. LOUIS – A group of 50 researchers from around the globe, including biology professors Daniel Warren, Ph.D., from Saint Louis University and Leslie Buck, Ph.D., from the University of Toronto, have spent the last several years sequencing and analyzing the genome of the western painted turtle and the results of their research point to some important conclusions that may be important for human health.

Whether human or hyena, there's safety in numbers

Humans, when alone, see threats as closer than they actually are. But mix in people from a close group, and that misperception disappears.

In other words, there's safety in numbers, according to a new study by two Michigan State University scholars. Their research provides the first evidence that people's visual biases change when surrounded by members of their own group.

New technology that improves your brain

TAMPA, Fla. (April 23, 2013) – Improving brain function is one of the topics explored in the latest issue of Technology and Innovation – Proceedings of the National Academy of Inventors® (https://www.cognizantcommunication.com/component/content/article/636).

Decoding touch

We know the world through the sensory representations within our brain. Such "reconstruction" is performed through the electrical activation of neural cells, the code that contains the information that is constantly processed by the brain. If we wish to understand what are the rules followed by the representation of the world inside the brain we have to comprehend how electrical activation is linked to the sensory experience.

New research examines connection between inflammatory stimulus and Parkinson's disease

BOSTON—Parkinson's disease (PD) is a progressive degenerative disease affecting a person's ability to coordinate and control their muscle movement. What starts out as a tremor in a finger will eventually lead to difficulty in writing and speaking, and ultimately the inability to walk without assistance. Since the 1950s research has shown that people with Parkinson's have decreased levels of the chemical dopamine in their brains, which is involved in sending messages to the part of the brain that controls coordination and movement.

Humans feel empathy for robots

Washington, DC (April 18, 2013) – From the T-101 to Data from Star Trek, humans have been presented with the fictional dilemma of how we empathize with robots. Robots now infiltrate our lives, toys like Furbies or robot vacuum cleaners bring us closer, but how do we really feel about these non-sentient objects on a human level? A recent study by researchers at the University of Duisburg Essen in Germany found that humans have similar brain function when shown images of affection and violence being inflicted on robots and humans.

Rescue me: New study finds animals do recover from neglect

Animal sanctuaries can play an important role in rehabilitating goats and other animals that have suffered from neglect, according to scientists at Queen Mary, University of London.

Atrophy in key region of brain associated with multiple sclerosis

OAK BROOK, Ill. – Magnetic resonance imaging (MRI) measurements of atrophy in an important area of the brain are an accurate predictor of multiple sclerosis (MS), according to a new study published online in the journal Radiology. According to the researchers, these atrophy measurements offer an improvement over current methods for evaluating patients at risk for MS.

National study: Teen misuse and abuse of prescription drugs up 33 percent since 2008

New York, NY – April 23, 2013 – New, nationally projectable survey results released today by The Partnership at Drugfree.org and MetLife Foundation confirmed that one in four teens has misused or abused a prescription (Rx) drug at least once in their lifetime – a 33 percent increase over the past five years. The Partnership Attitude Tracking Study (PATS) also found troubling data on teen misuse or abuse of prescription stimulants.

Gone, but not forgotten

An international team of neuroscientists has described for the first time in exhaustive detail the underlying neurobiology of an amnesiac who suffered from profound memory loss after damage to key portions of his brain.

New light shed on early stage Alzheimer's disease

The disrupted metabolism of sugar, fat and calcium is part of the process that causes the death of neurons in Alzheimer's disease. Researchers from Karolinska Institutet in Sweden have now shown, for the first time, how important parts of the nerve cell that are involved in the cell's energy metabolism operate in the early stages of the disease. These somewhat surprising results shed new light on how neuronal metabolism relates to the development of the disease.

Scientists find antibody that transforms bone marrow stem cells directly into brain cells

LA JOLLA, CA – April 22, 2013 – In a serendipitous discovery, scientists at The Scripps Research Institute (TSRI) have found a way to turn bone marrow stem cells directly into brain cells.

'Clean' your memory to pick a winner

Predicting the winner of a sporting event with accuracy close to that of a statistical computer programme could be possible with proper training, according to researchers.

In a study published today, experiment participants who had been trained on statistically idealised data vastly improved their ability to predict the outcome of a baseball game.

Large animal models of Huntington's disease offer new and promising research options

Amsterdam, NL, 22 April 2013 – Scientific progress in Huntington's disease (HD) relies upon the availability of appropriate animal models that enable insights into the disease's genetics and/or pathophysiology. Large animal models, such as domesticated farm animals, offer some distinct advantages over rodent models, including a larger brain that is amenable to imaging and intracerebral therapy, longer lifespan, and a more human-like neuro-architecture.
