One of the leading causes of blindness worldwide could be detected by how our eyes respond to watching TV according to a new study from researchers at City University London.
The researchers, who were funded by the UK charity Fight for Sight, found that they could identify diseases such as glaucoma by looking at maps of people's eye movements while they watched a film.

With the help of mouse models, induced pluripotent stem cells (iPSCs) and the "tooth fairy," researchers at the University of California, San Diego School of Medicine have implicated a new gene in idiopathic or non-syndromic autism. The gene is associated with Rett syndrome, a syndromic form of autism, suggesting that different types of autism spectrum disorder (ASD) may share similar molecular pathways.
The findings are published in the Nov. 11, 2014 online issue of Molecular Psychiatry.

Imagine being able to recognize your car as your own but never being able to remember where you parked it. Researchers at University of California, San Diego School of Medicine have induced this all-too-common human experience - or a close version of it - permanently in rats and from what is observed perhaps derive clues about why strokes and Alzheimer's disease can destroy a person's sense of direction.
The findings are published online in the current issue of Cell Reports.

Turns out your mom was right: Scratching an itch only makes it worse. New research from scientists at Washington University School of Medicine in St. Louis indicates that scratching causes the brain to release serotonin, which intensifies the itch sensation.
The findings, in mice, are reported online in the journal Neuron. The same vicious cycle of itching and scratching is thought to occur in humans, and the research provides new clues that may help break that cycle, particularly in people who experience chronic itching.

As football players are learning, a violent blow to the head has the potential to cause mild to severe traumatic brain injury -- physical damage to the brain that can be debilitating, even fatal. The long-term effects run the gamut of human functioning, from trouble communicating to extensive cognitive and behavioral deterioration. To date, there is no effective medical or cognitive treatment for patients with traumatic brain injuries.

Prolonged periods of deployment among the UK's armed forces have fallen since the introduction of the "Harmony Guidelines" to limit tours of overseas duty--which might have led to a reduction in mental health problems, new research published in The Lancet Psychiatry journal suggests.

A darting mouse may hold an important clue in the development of Attention Deficit Hyperactivity Disorder (ADHD), autism and bipolar disorder, according to a study by a Vanderbilt University-led research team recently published in the Proceedings of the National Academy of Sciences.
The transgenic mouse, into which was inserted a rare human genetic variation in the dopamine transporter (DAT), could lead to improvements in the diagnosis and treatment of these all-too-common brain disorders, said Randy Blakely, Ph.D., the report's senior author.

BUFFALO, N.Y. - Most people rarely sing publicly outside of a duty-bound rendition of "Happy Birthday." And since that particular song is usually offered as a group performance, even the reluctant join in the spirit of the occasion, hoping their individual shortcomings will be cloaked by the chorus.
