Disruptive behaviors in childhood are among the most prevalent and costly mental health problems in industrialized countries and are associated with significant negative long-term outcomes for individuals and society. Recent evidence suggests that disruptive behavioral problems in the first years of life are an important early predictor of lower employment earnings in adulthood. A new […]Continue Reading ...
Atlas Award-winning study in Journal of Affective Disorders shows link between depression and sedentary behavior is strongest in cities Getting people involved in community activities like playing games and social events could be a low-cost way to tackle depression in the developing world, according to a study in the Journal of Affective Disorders. Sedentary behavior […]Continue Reading ...
WEDNESDAY, Dec. 26, 2018 — You’ve probably seen movies where a veteran returns home from the horrors of war and wakes in the middle of the night yelling, punching or flailing so much that they harm themselves or a sleep partner. This isn’t just Hollywood drama. New research has identified who’s most at risk for […]Continue Reading ...
Johns Hopkins researchers have observed a previously unrecognized behavior in a single-celled parasite called Spironucleus vortens, which infects ornamental fish such as angelfish: The protozoans swarm. Different species of Spironucleus infect other species of fish, amphibians, reptiles, birds and mammals, though this parasite family is not a threat to human health. One notorious member of […]Continue Reading ...
Call it instinct, but something compels some animals to behave in certain ways, perhaps programs in their genes. Researchers have directly connected activities of genes with instinctive behavior in little male fish that make patterns in the sand to attract their mates. Scientists at the Georgia Institute of Technology and Stanford University who led the […]Continue Reading ...
New research from the University at Buffalo has, for the first time, identified differences between men and women in their preferences for maintaining comfort both while exercising and in recovery. The results could one day inform the development of new athletic apparel. The human body has a variety of automatic mechanisms in place to respond […]Continue Reading ...
Our responsiveness to seeing others in distress accounts for variability in helping behavior from early in development, according to a study published Sept. 25 in the open-access journal PLOS Biology by Tobias Grossmann from the Max Planck Institue for Human Cognitive and Brain Sciences (MPI CBS) and the University of Virginia, and his team. Altruistic […]Continue Reading ...
At right, a close-up of mouse brain tissue shows an engineered protein (stained green) being expressed by astrocytes, but no other cells. UCLA scientists used this technique to selectively silence astrocytes to explore their roles in mouse behavior. Credit: UCLA Health Repetitive behavior disorders are relatively common. One of the best known in this family […]Continue Reading ...
Feeding behavior and social stimulation activate intermingled but distinct brain circuits, and activating one circuit can inhibit the other, according to a new study by researchers at Stanford University. The researchers demonstrated in mice that direct stimulation of fewer than two dozen nerve cells, or neurons, linked to social interaction was enough to suppress the […]Continue Reading ...
It may seem like one of the cruelest aspects of the natural world, but research has shown that infanticide is actually an instinctive behavior in many animals – and Catherine Dulac has begun deciphering the chemical and other sensory cues that drive the behavior. The Higgins Professor of Molecular and Cellular Biology and the Lee […]Continue Reading ...
Many species of mammals have evolved what appear to be paradoxical behaviors towards their young. Like humans, most exhibit nurturing, protective behaviors, and in some circumstances even act as surrogate parents. However, virgin males often engage in infanticide as a strategy to propagate their own genes. How are these conflicting social behaviors controlled? Research published […]Continue Reading ...
Researchers at the University of Zurich and Harvard University have developed a new strategy in the search for psychoactive drugs. By analyzing the behavior of larval zebrafish, they can filter out substances with unwanted side effects right from the start. This method has resulted in the discovery of a number of new appetite modulators. Many […]Continue Reading ...
In the current issue of Family Medicine and Community Health (Volume 6,Number 3, 2018, pp.115-123, researchers Bishwajit Ghose and Sanni Yaya of the Faculty of Social Sciences, School of International Development and Global Studies University of Ottawa, Ottawa, ON, Canada, describe how this study is the first to assess the effect of socioeconomic status on […]Continue Reading ...
An international team of researchers consisting of scientists from NUST MISIS and TU Dortmund University has developed a technology to study the behavior of orthopedic implants in laboratory conditions as close as possible to the human body. The technology is notable for its ethics: the research can be carried out in vitro – that is, […]Continue Reading ...
Why do some people comfortably walk between skyscrapers on a high-wire or raft the Niagara Falls in a wooden barrel whereas others freeze on the mere thought of climbing off escalators in a shopping mall? In a new study, scientists have found that a certain type of cells in the hippocampus play a key role. […]Continue Reading ...
