Going Straight To Your Head

If you live with your cell phone pinned to your ear, listen up. Scientists at Britain's Bristol University have been testing model heads, complete with "liquid brains," to analyze the reaction of fake flesh and brain matter to the cell phone's high-frequency radio waves. According to Dr. Alan Preece, the amount of harmful waves emitted can differ between phone models by as much as a factor of 40. The heads, made from real skulls, saltwater, modeling clay and antifreeze, have been monitored for the past two years with radiation-sensitive probes. MRI images will be compared with those of living patients, and results will be sent to European Union officials to set new cell-phone safety standards by the end of the year.
