Cell phone radiation may prevent or even cure Alzheimer's disease
University of South Florida researchers exposed 96 mice, some bred to develop Alzheimer's-like disease, to cell phone radiation. Treated mice matched normal aged mice on cognitive tests, memory loss reversed in older Alzheimer's mice, and the waves erased beta-amyloid deposits.
