Lab rats with cellphones?

[Commentary] We love our digital gadgets -- "magic" devices that define cool and promise to remake our lives for the better. But there is growing evidence of a dark side to the techno-magic. Your cellphone, and any other wireless device that depends on electromagnetic (EM) microwave radiation to function, may be hazardous to your health. Most of the bad news comes from major labs and research institutions in Europe. What they're reporting is that using cellphones and Wi-Fi transmitters -- which operate using similar frequencies -- can have biological effects on the brain and body. The scientific debate remains heated and far from resolved. But the research to date suggests a number of chilling possibilities as to what EM radiation may be doing to us.
