Bidis are popular with adolescents because many perceive them to be less of a risk to health than regular cigarettes, and because they are manufactured in a variety of flavors, such as chocolate or root beer.

Fasting forestalls Huntington's disease in mice

Decreasing meal frequency and caloric intake protects nerve cells from genetically induced damage, delays the onset of Huntington’s disease-like symptoms in mice, and prolongs the lives of affected rodents, according to investigators at the National Institute on Aging (NIA) Intramural Research Program. This animal study* is the first to suggest that a change in diet can influence the course of Huntington’s disease.

New strategy may protect brain against stroke, Parkinson’s and Alzheimer’s

Federal researchers say they’ve developed several drug candidates that show promise in protecting the brain against damage from stroke, with the potential to fight chronic neurodegenerative conditions like Parkinson’s and Alzheimer’s disease as well.. The drugs, called p53 inhibitors, attack a key protein involved in nerve cell death and represent a new strategy for preserving brain function following sudden injury or chronic disease.
