Researchers discover a biological marker of dyslexia

Though learning to read proceeds smoothly for most children, as many as one in 10 is estimated to suffer from dyslexia, a constellation of impairments unrelated to intelligence, hearing or vision that make learning to read a struggle. Now, Northwestern University researchers report they have found a biological mechanism that appears to play an important [...]

Older brains more vulnerable to fraud

An ancient warning system in the brain fails to fire in older people making them especially vulnerable to fraud, finds a US study. The brain region called the anterior insula is activated when young adults look at pictures of untrustworthy faces, but fails to respond when older adults see the pictures, reports Professor Shelley Taylor [...]

Girls may be protected against autism

A team of Boston and European scientists have found evidence for a “female protective effect” in autism that could explain why boys are at far greater risk for the disorder than girls. For years, it’s been known that boys are disproportionately affected by autism spectrum disorders, outnumbering girls four to one. What has never been [...]

TV watching linked to bad behaviour

Children and adolescents who watch a lot of television are more likely to become involved in antisocial and criminal behaviour as adults, a University of Otago study indicates. One of the study co-authors, Associate Prof Bob Hancox, said the research showed the issue of excessive television watching needed to be ''taken seriously''. Researchers found the [...]

HPV Vaccine Does Not Raise Risk for Sexual Activity

Adolescent girls who get the human papillomavirus (HPV) vaccine are no more likely to show signs they may be engaging in sexual activity than girls who do not get the vaccine, according to a new study that challenges a widely held belief. HPV is the most common sexually transmitted virus, and some strains of the [...]

Barack Obama and the ’empathy deficit’

In 2011, researchers at the University of Chicago conducted a simple experiment to ascertain whether a rat would release another rat from a cage without being given a reward. The answer was yes. After several sessions, the rats learned intentionally and quickly to open the restrainer and release the caged rats. The rats also repeated [...]

Could PET scans detect brain injury caused by football?

For years, researchers have had to use tissue obtained posthumously to diagnose chronic traumatic encephalopathy, or C.T.E., the degenerative brain disease that has bedeviled athletes, soldiers and others who have sustained repeated head hits and concussions. via Study Suggests PET Scan May Identify C.T.E. in Living Patients - NYTimes.com.

6 scientific insights into increasing happiness

1. Surround yourself with happy people Or surround yourself with people who surround themselves with happy people. A longitudinal investigationconducted over 20 years in collaboration with the Framingham Heart Study revealed that shifts in individual happiness can cascade through social networks like an emotional contagion (The researchers don't mean Facebook, btw, but physical, old-school networks — like live-in [...]

Diet drinks linked with higher depression risk

Sweet beverages, and especially diet versions, could make you 30 per cent more depressed. Coffee, however, saves the day according to research by US scientists. The study was conducted by the National Institutes of Health, the National Institute of Environmental Health Sciences and the National Cancer Institute. The research involved 265,000 people between the ages [...]

In Brain, Competing Thoughts Come in Waves and Rhythms

Despite significant advances in brain imaging and cognitive science, neuroscientists continue to search for how the brain develops and retains perceptions and memories. Emerging evidence suggests that a group of neurons can represent each unique piece of information, but no one knows just what these ensembles look like, or how they form. In a new [...]
