Scientists at Harvard University have sketched a new map of the evolutionary labyrinth species must traverse to reach eusociality, the rare but spectacularly successful social structure where individuals cooperate to raise offspring.
In an unconscious attempt to outdo female rivals, ovulating women buy sexier clothing, according to a new study in the Journal of Consumer Research.
Oxytocin (OT) is a hormone that plays an important role in social behavior—it has even been nicknamed “the love hormone” and “liquid trust.” Increased levels of OT have been associated with greater caring, generosity, and trust. But does OT increase people’s trust in just anybody or does it act more selectively?
Adults with attention-deficit/hyperactivity disorder (ADHD) who received medication and individual sessions of cognitive behavioral therapy (CBT) showed greater improvement in symptoms through 12 months compared to patients who did not receive CBT, according to a study in the August 25 issue of JAMA.
The placement of alcohol-based hand disinfectants in businesses can reduce illness and absenteeism amongst the work force. A study published in the open access journal, BMC Infectious Diseases, has found that incidences of absenteeism in public administrations due to the common cold, fever and cough are significantly reduced when alcohol-based hand disinfectants are used by employees.
Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Medical Research Council (MRC) have successfully used a drug to reset and restart the natural 24 hour body clock of mice in the lab. The ability to do this in a mammal opens up the possibility of dealing with a range of human difficulties including some psychiatric disorders, jet lag and the health impacts of shift work.
Mutations in a single gene can cause several types of developmental brain abnormalities that experts have traditionally considered different disorders. With support from the National Institutes of Health, researchers found those mutations through whole exome sequencing – a new gene scanning technology that cuts the cost and time of searching for rare mutations.
In a new study on British Sign Language, signers made different mistakes in the sign and in the mouthing—which means the hand and lip movements are separate in the signer’s brain, not part of the same sign.
Children who were exposed to organophosphate pesticides while still in their mother’s womb were more likely to develop attention disorders years later, according to a new study by researchers at the University of California, Berkeley.
A regulatory protein best known for its role in a rare genetic brain disorder also may play a critical role in cocaine addiction, according to a recent study in rats, funded by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health. The study was published today in the journal Nature Neuroscience.
Watching superheroes beat up villains may not be the best image for boys to see if society wants to promote kinder, less stereotypical male behaviors, according to psychologists who spoke at the 118th Annual Convention of the American Psychological Association.
Women and girls in the United States consider and engage in suicidal behavior more often than men and boys, but die of suicide at lower rate-a gender paradox enabled by U.S. cultural norms of gender and suicidal behavior, according to a psychologist who spoke Thursday at the 118th Annual Convention of the American Psychological Association.
