Wolves were domesticated more than 15,000 years ago and it is widely assumed that the ability of domestic dogs to form close relationships with humans stems from changes during the domestication process. But the effects of domestication on the interactions between the animals have not received much attention. The point has been addressed by Friederike Range and Zsófia Virányi, two members of the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) who work at the Wolf Science Center (WSC) in Ernstbrunn, Niederösterreich.

LOS ANGELES (Jan. 30, 2014) – A multicenter research team led by Cedars-Sinai neurologist Nancy Sicotte, MD, an expert in multiple sclerosis and state-of-the-art imaging techniques, used a new, automated technique to identify shrinkage of a mood-regulating brain structure in a large sample of women with MS who also have a certain type of depression.
TAMPA, Fla. – Children with depression are more likely to be obese, smoke and be inactive, and can show the effects of heart disease as early as their teen years, according to a newly published study by University of South Florida Associate Professor of Psychology Jonathan Rottenberg.
The research, by Rottenberg and his colleagues at Washington University and the University of Pittsburgh, suggests that depression may increase the risk of heart problems later in life.
UC San Francisco researchers are reporting a detailed account of how speech sounds are identified by the human brain, offering an unprecedented insight into the basis of human language. The finding, they said, may add to our understanding of language disorders, including dyslexia.
Scientists have known for some time the location in the brain where speech sounds are interpreted, but little has been discovered about how this process works.
Physicians have long known that oxygen deprivation to the brain around the time of birth causes worse damage in boys than girls. Now a study by researchers from the Johns Hopkins Children's Center conducted in mice reveals one possible reason behind this gender disparity and points to gender-specific mechanisms of brain repair following such injury.
According to the National Institute of Mental Health, over 18 percent of American adults suffer from anxiety disorders, characterized as excessive worry or tension that often leads to other physical symptoms. Previous studies of anxiety in the brain have focused on the amygdala, an area known to play a role in fear. But a team of researchers led by biologists at the California Institute of Technology (Caltech) had a hunch that understanding a different brain area, the lateral septum (LS), could provide more clues into how the brain processes anxiety.
WASHINGTON, D.C., January 30, 2014 ─ The January/February 2014 issue of Educational Researcher (ER), a peer-reviewed journal of the American Educational Research Association (AERA), is now available on the association's website.

Spanish researchers have managed to distinguish between different varieties of beer using an electronic tongue. The discovery, published in the journal 'Food Chemistry', is accurate in almost 82% of cases.
Beer is the oldest and most widely consumed alcoholic drink in the world. Now, scientists at the Autonomous University of Barcelona have led a study which analysed several brands of beer by applying a new concept in analysis systems, known as an electronic tongue, the idea for which is based on the human sense of taste.
Park Ridge, Ill. (January 30, 2014) - Recent research published in the American Journal of Clinical Nutrition (AJCN) found that during pregnancy, and particularly during the third trimester, large amounts of choline may be needed to support fetal development. Conclusions of the research revealed that current recommendations may be too low.1 Choline deficiency in pregnant women may result in elevated levels of homocysteine, potentially resulting in birth defects.
Infants as young as six months old tend to expect that plants are food sources, but only after an adult shows them that the food is safe to eat, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
The findings show that, after watching an adult put part of a plant and part of a man-made object in her mouth, infants at 6- and 18-months of age preferentially identify the plant as the food source.
New research from Karolinska Institutet in Sweden shows that medication used to treat ADHD in adult men can save lives on the road. According to a large registry study, which is now being published in the scientific journal JAMA Psychiatry, up to half of the transport accidents involving men with ADHD could be avoided if the men were taking medication for their condition.
DALLAS – January 29, 2014 – Exposure to DDT may increase the likelihood of developing Alzheimer's disease later in life, a study with researchers at UT Southwestern Medical Center suggests. While previous studies have linked chronic diseases such as cancer and diabetes to DDT, this is the first clinical study to link the U.S.-banned pesticide to Alzheimer's disease.
CHAMPAIGN, Ill. — A quick glance at two, unequal groups of paper clips (or other objects) leads most people to immediately intuit which group has more. In a new study, researchers report that practicing this kind of simple, instinctive numerical exercise can improve children's ability to solve math problems.
A report of the study appears in the journal Cognition.
Researchers led by Marta Barrachina, Institute of Neuropathology of the Bellvitge Biomedical Research Institute (IDIBELL) have identified a new subgroup of patients suffering from schizophrenia characterized by motor disorders.
