A short burst of intensive exercise before eating a high fat meal is better for blood vessel function in young people than the currently recommended moderate-intensity exercise, according to a new study from the University of Exeter. Cardiovascular diseases including heart attacks and stroke are the leading cause of death in the UK, and the process underlying these diseases start in youth. An impairment in the function of blood vessels is thought to be the earliest event in this process, and this is known to occur in the hours after consuming a high fat meal.

In a remarkable demonstration of the curative power of memory, published in Nature, scientists have established that artificial reactivation of memories stored during a positive experience can suppress the effects of stress-induced depression. The research, conducted by scientists at the RIKEN-MIT Center for Neural Circuit Genetics, a joint collaboration of RIKEN Brain Science Institute in Japan and MIT, shows how positive and negative memories interact in mood disorders, and provides a specific brain circuit for future clinical interventions.

Toxic chemicals may be triggering the recent increases in neurodevelopmental disabilities among children -- such as autism, attention-deficit hyperactivity disorder, and dyslexia -- according to a new study from Harvard School of Public Health (HSPH) and Icahn School of Medicine at Mount Sinai. The researchers say a new global prevention strategy to control the use of these substances is urgently needed. The report will be published online February 15, 2014 in Lancet Neurology.

Carnegie Mellon researchers identify brain regions that encode words, grammar, story

Some people say that reading "Harry Potter and the Sorcerer's Stone" taught them the importance of friends, or that easy decisions are seldom right. Carnegie Mellon University scientists used a chapter of that book to learn a different lesson: identifying what different regions of the brain are doing when people read. Researchers from CMU's Machine Learning Department performed functional magnetic resonance imaging (fMRI) scans of eight people as they read a chapter of that Potter book...
