When a certain protein is mutated or missing, symptoms of the neurodevelopmental disorder Rett syndrome arise, causing a gradual loss of brain function during early development.

Stress in middle age could contribute to late-life dementia
Psychological stress in middle age could lead to the development of dementia later in life, especially Alzheimer's disease, reveals research from the University of Gothenburg, Sweden.

Today's superheroes send wrong image to boys, say researchers
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 Sunday at the 118th Annual Convention of the American Psychological Association.

Sex between adolescents in romantic relationships is often harmless to their academics
The context in which adolescent sexual activity occurs can substantially moderate the negative relationship between sexual intercourse and education, according to research to be presented at the 105th Annual Meeting of the American Sociological Association.

Better treatment of atrial fibrillation and its risks
The earlier that patients who suffer from atrial fibrillation obtain the correct treatment, the lower is the risk of serious secondary effects such as stroke.

Cultural capital is key to preparing for college and getting into a good school
An Indiana University researcher found that students with low-income or minority status do not prepare for college in the same way as their more privileged counterparts, regardless of their academic ability or plans to attend college.

Probing the nanoparticle: Predicting how nanoparticles will react in the human body
Researchers at North Carolina State University have developed a method for predicting the ways nanoparticles will interact with biological systems -- including the human body.
