Growing up poor can suppress a child’s genetic potential to excel cognitively even before the age of 2, according to research from psychologists at The University of Texas at Austin.
Whether it’s a company with local and ex-pat employees, countries in need of aid, or the elderly interacting with the young, a new research paper to be published in the journal Psychological Science says recognizing diversity can actually encourage people to help each other instead of sparking conflict.
Employees who have to maintain a neutral disposition while they are on the clock tend to spend more energy to meet that requirement; therefore, they have less energy to devote to work tasks, according to new research from Rice University, the University of Toronto and Purdue University.
The Newcastle University researchers Dr Marcus Kaiser and Mrs Sreedevi Varier carried out a sophisticated computer analysis relating birth-time associated data to connectivity patterns of nerve cells in the roundworm, Caenorhabditis elegans. They demonstrated that when two nerve cells develop close together, they form a connection which then stretches out when the two nerve cells move apart as the organism grows. This creates a link across the brain known as a long-distance connection.
Hope for new ways of treating devastating neurodegenerative disorders such as Huntington’s disease has been raised by a trans-Atlantic team of researchers thanks to the use of cutting-edge genetic techniques.
Scientists in Connecticut have carried out one of the first psychological studies into eating disorders in Native American (NA) populations. The research, published in The International Journal of Eating Disorders, provides new insights into the extent to which Native American populations experience eating disorders, revealing that women are more likely to report behavioral symptoms then men, while challenging views that NA men and ethnically white men will experience different psychological symptoms.
Carnegie Mellon University researchers have found that within the brain’s neocortex lies a subnetwork of highly active neurons that behave much like people in social networks. Like Facebook, these neuronal networks have a small population of highly active members who give and receive more information than the majority of other members, says Alison Barth, associate professor of biological sciences at Carnegie Mellon and a member of the Center for the Neural Basis of Cognition (CNBC).
Most college students in the United States do not grasp the scientific basis of the carbon cycle – an essential skill in understanding the causes and consequences of climate change, according to research published in the January issue of BioScience.
Many prescriptions for the top-selling class of drugs, known as atypical antipsychotic medications, lack strong evidence that the drugs will actually help, a study by researchers at the Stanford University School of Medicine and University of Chicago has found. Yet, drugs in this class may cause such serious effects as weight gain, diabetes and heart disease, and cost Americans billions of dollars.
Emotional crying is a universal, uniquely human behavior. When we cry, we clearly send all sorts of emotional signals. In a paper published online today in Science Express, scientists at the Weizmann Institute have demonstrated that some of these signals are chemically encoded in the tears themselves. Specifically, they found that merely sniffing a woman’s tears – even when the crying woman is not present — reduces sexual arousal in men.
A substantial proportion of youth with severe mental disorders do not receive mental health care, according to data from an NIMH-funded survey published in the January 2011 issue of the Journal of the American Academy of Child and Adolescent Psychiatry.
Brain scans of children with attention-deficit/hyperactivity disorder (ADHD) have shown for the first time why people affected by the condition sometimes have difficulty in concentrating. The study, by experts at The University of Nottingham, may explain why parents often say that their child can maintain concentration when they are doing something that interests them, but struggles with boring tasks.
