Grossip Gossip can be entertaining. We often thirst for it and delight in its consumption. There is also a dark side, however. Please don’t go there.
Lack of D1 receptor leads to slowness of movements in Parkinson’s disease Dopamine deficiency in the basal ganglia (a set of subcortical structures) causes severe motor dysfunctions, such as slowness of movements (bradykinesia), as observed in Parkinson’s disease. Dopamine binds D1 and D2 receptors that are expressed in the nerve cells of the striatum (a structure of the basal ganglia), and exerts different effects on the nerve [...]
Predicting which soldiers will commit severe, violent crimes Workplace violence perpetrated by military personnel is a major concern of the U.S. Department of Defense (DoD). Although programs have been implemented to teach violence prevention strategies to all military personnel, such programs are much less intensive than others developed in settings for people judged to be at high risk of violent behavior. But what [...]
People with higher ‘intellectual arrogance’ get better grades, study finds People who think they know it all — or at least, a lot — may be on to something, according to a Baylor University study. The finding was a surprise to researchers at Baylor and the University of Mary Hardin-Baylor, who had theorized that “intellectual humility” — having an accurate or moderate view of one’s [...]
Extremely active rats become lazy when they artificially receive 'runners' high' Researchers have found that activating the pleasure and reward receptors in the brain could provide the 'reward' of dangerous drugs without having to consume those drugs.
Researchers discover mutation involved in neurodegeneration A mutation that increases the level of a special class of sphingolipids–molecules important to cell structure and signaling–can lead to neurodegeneration due to problems with neuronal membranes, reports a research team led by Jackson Laboratory Research Scientist Lihong Zhao, Ph.D. and Professor Patsy Nishina, Ph.D. Sphingolipids are a family of biological molecules structurally related to [...]
Heavy internet use may put teens at risk for high blood pressure Teens who spend hours on the Internet may be at risk for high blood pressure, say researchers at Henry Ford Hospital in Detroit. In a study published in the Journal of School Nursing, researchers found that teens who spent at least 14 hours a week on the Internet had elevated blood pressure. Of 134 teens [...]
How the brain’s wiring leads to cognitive control How does the brain determine which direction to let its thoughts fly? Looking for the mechanisms behind cognitive control of thought, researchers at the University of Pennsylvania, University of California and United States Army Research Laboratory have used brain scans to shed new light on this question. By using structural imaging techniques to convert brain [...]
Study shows how dominant parents affect kids’ self-worth Children’s self-esteem is linked to the behaviour of who is considered the most powerful parent within the household, new University of Sussex research suggests. The study of English and Indian families living in Britain is the first to assess the impact on a child’s wellbeing of the household power structures that exist within different cultures. [...]
When Abuse Becomes Denial “The victim who is able to articulate the situation of the victim has ceased to be a victim: he or she has become a threat.” — James Baldwin I used to think that abuse victims who lived in denial of their situations had to know … ...
4 Small Signs of Depression Often times when we think of depression we picture a person sitting in bed all alone, not showered, with a sad look on their face. But depression doesn’t always have … ...
Information diffusion: How to mathematically make something go viral on Facebook Researchers at Chapman University have proposed a strategic approach for information spreading via Facebook using cancer screenings as a health intervention. In a study called, “Information diffusion, Facebook clusters, and the simplicial model of social aggregation: a computation simulation of simplicial diffusers for community health interventions,” they use Facebook to identify social clusters and opinion [...]
Anxiety Sufferers: You Might Just Be Too Smart If you suffer from anxiety, social or otherwise, you might be tempted to think that your brain is just ‘broken.’ However, there is evidence to suggest that you might rather … ...
The science of retweets: Researchers forecast user engagement on social media What’s the best time to tweet, to ensure maximum audience engagement? Researchers at the University of Maryland have demonstrated that an algorithm that takes into account the past activity of each of your followers — and makes predictions about future tweeting — can lead to more “retweets” than other commonly used methods, such as posting [...]
NIH scientists identify how normally protective immune responses kill neurons National Institutes of Health (NIH) scientists studying inflammation of the brain have discovered why certain immune responses, which typically help cells recognize and fight viral and bacterial infections, can sometimes be harmful to the brain. Many brain disorders involve the death of neurons, or nerve cells, but how these neurons die is not well understood. [...]
Children learn from stress and failure: all the more reason you shouldn’t do their homework A recent report by the NSW Board of Studies, Teaching and Educational Standards has suggested that parents are helping children cheat by completing their school homework, and has called for this issue to be addressed. But does helping your child with homework hinder their progress? The answer to this question is not simple. So far, [...]
Analysis of chronic pain drug trials shows increasing placebo responses over time — in the US only A new study finds that rising placebo responses may play a part in the increasingly high failure rate for clinical trials of drugs designed to control chronic pain caused by nerve damage. Surprisingly, however, the analysis of clinical trials conducted since 1990 found that the increase in placebo responses occurred only in trials conducted wholly [...]
Repeating things aloud to another person boosts memory recall, study finds Repeating aloud boosts verbal memory, especially when you do it while addressing another person, says Professor Victor Boucher of the University of Montreal’s Department of Linguistics and Translation. His findings are the result of a study that will be published in the next edition of Consciousness and Cognition. “We knew that repeating aloud was good [...]
Approach or buzz off: Brain cells in fruit fly hold secret to individual odor preferences Responding appropriately to the smell of food or the scent of danger can mean life or death to a fruit fly, and dedicated circuits in the insect’s brain are in place to make sure the fly gets it right. In studies designed to better understand how the brain processes information, scientists led by Cold Spring [...]
Understanding others’ thoughts enables young kids to lie Kids who are taught to reason about the mental states of others are more likely to use deception to win a reward, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The findings indicate that developing “theory of mind” (ToM) — a cognitive ability critical to many social [...]
