that occur with age. The results may also help to explain the basis of common neurological disorders such as Parkinson's and Alzheimer's diseases. Cheol-Koo Lee, Richard Weindruch and Tomas A. Prolla, all of UW-Madison, profiled the action of 6,347 g...

as a "smoking gun" in impulsive violence, Davidson cautions that science is a long way from developing any preventive strategy for at-risk populations. Davidson's future studies will explore this complex brain process in much greater detail, through ...
