Cell phone use might actually help prevent Alzheimer's disease! Really?

The Journal of Alzheimer's Disease has reported that researchers exposed normal mice and mice genetically bred to develop Alzheimer's disease (AD) to electromagnetic fields (EMF) at frequencies equivalent to cell phones for 2 hours each day. After 7-9 months those mice exposed to the EMF were actually protected against cognitive impairment, and  AD-like symptoms were reversed in the mice predisposed to AD. Improved cognitive performance was measured in the normal mice, too.
