I ran across news of this study the other day and thought it was interesting. Makes me feel slightly better for all the time I’ve spent on my Palm Pre!

The study, conducted in mice, appears online in the Journal of Alzheimer’s Disease.

Researchers exposed normal mice and AD-transgenic mice to electromagnetic fields (EMFs) for 2 hours each day, for 7 to 9 months, at frequencies equivalent to typical cell phone use. When the researchers compared these mice with unexposed mice, they found that EMF exposure protected against cognitive impairment and reversed AD-like neuropathology in transgenic mice, as well as improved cognitive performance in normal mice. 

The authors, who advise caution when applying these findings to humans, propose several potential mechanisms of action, including increased amyloid-beta clearance from the brain and increased cerebral blood flow with EMF exposure.
