Young children instinctively use a 'language-like' structure to communicate through gestures.
Research led by the University of Warwick suggests when young children are asked to use gestures to communicate, their gestures segment information and reorganise it into language-like sequences. This suggests that children are not just learning language from older generations, their preference for communication has shaped how languages look today.
The current state of science on the adverse health effects of marijuana use links the drug to several significant adverse effects including addiction, a review reports. The article, published today in the New England Journal of Medicine, is authored by scientists from the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health.
"These findings provide strong evidence that these electrical oscillations in the alpha frequency band play a key role in a person's ability to store a limited number of items in working memory," Awh said. "By identifying particular rhythms that are important to memory, we're getting closer to understanding the low-level building blocks of this really limited cognitive ability.
Quebec City, June 5, 2014—A recent study published in Annals of Neurology reports that healthy human tissue grafted to the brains of patients with Huntington's disease in the hopes of treating the neurological disorder also developed signs of the illness, several years after the graft. This discovery will have profound implications on our understanding of the disease and how to treat it, and may also lead to the development of new therapies for neurodegenerative disorders.
Entitled attitudes appear to be linked to sexism—even among women, according to a personality study by psychologists from Case Western Reserve University and San Diego State University. In general, entitled men are more likely to endorse hostile views of women and entitled women are more likely to endorse views of women as frail and needing extra care.
If you're trying to outwit the competition, it might be better to have been born a chimpanzee, according to a study by researchers at Caltech, which found that chimps at the Kyoto University Primate Research Institute consistently outperform humans in simple contests drawn from game theory.
After Mitt Romney was defeated by President Barack Obama in the 2012 presidential election, some political pundits and even Romney himself tried to pin the loss in part on Hurricane Sandy.
Observers, particularly conservatives, believed the storm was an "October surprise" that allowed Obama to use the trappings of his office to show sympathy and offer support for the victims. The devastating storm hit a week before Election Day, killing hundreds and causing more than $50 billion worth of damage.
PHILADELPHIA (June 4, 2014)— In a study that began as a sixth-grade science fair project, researchers at Drexel University have found that a popular non-nutritive sweetener, erythritol, may be an effective and human-safe insecticide.
Erythritol, the main component of the sweetener Truvia®, was toxic to Drosophila melanogaster fruit flies in a dose-dependent manner in the Drexel team's study, published in PLOS ONE. The flies consumed erythritol when sugar was available and even seemed to prefer it. No other sweeteners tested had these toxic effects.
If you're depressed, don't get enough exercise or have high blood pressure, you may find yourself complaining more about memory problems, even if you're a young adult, according to a new UCLA study.
UCLA researchers and the Gallup organization polled more than 18,000 people about their memory and a variety of lifestyle and health factors previously shown to increase the risk of Alzheimer's disease and dementia. They found that many of these risk factors increased the likelihood of self-perceived memory complaints across all adult age groups.
ANN ARBOR, Mich. – Pain medicines often lead to constipation for patients seeking long-term pain relief, but an investigational once-daily drug may help, according to study led by the University of Michigan Health System.
Globally, approximately 28 million to 35 million, or nearly half, of patients taking opioids for long-term pain develop constipation. Laxatives provide sub-optimal relief.
June 4, 2014 (Toronto) – Women nearing menopause have higher levels of a brain protein linked to depression than both younger and menopausal women, a new study by the Centre for Addiction and Mental Health (CAMH) shows.
This finding may explain the high rates of first-time depression seen among women in this transitional stage of life, known as perimenopause.
A team of UCLA researchers has identified a new gene involved in Parkinson's disease, a finding that may one day provide a target for a new drug to prevent and potentially even cure the debilitating neurological disorder.
JACKSONVILLE, Fla. — Neuroscientists at Mayo Clinic in Florida and at Aarhus University in Denmark have shed light on why neurons in the brain's reward system can be miswired, potentially contributing to disorders such as attention deficit hyperactivity disorder (ADHD).
A QUT scientist is hoping to unlock the potential of stem cells as a way of repairing neural damage to the brain.
Rachel Okolicsanyi, from the Genomics Research Centre at QUT's Institute of Health and Biomedical Innovation, said unlike other cells in the body which were able to divide and replicate, once most types of brain cells died, the damage was deemed irreversible.
Ms Okolicsanyi is manipulating adult stem cells from bone marrow to produce a population of cells that can be used to treat brain damage.
ROCHESTER, Minn. — Researchers at Mayo Clinic have demonstrated in a mouse model that their recently developed synthetic peptide carrier is a potential delivery vehicle for brain cancer chemotherapy drugs and other neurological medications. The findings appear in PLOS ONE.
