Every so often on the evening news we hear health experts giving us the latest scoop on the health dangers of cell phone and electronics usage. Some of us listen, and some of us don’t—indeed, conclusive evidence implicating cell phone radiation directly with harmful health risks has yet to be scientifically shown.

But now, in a study published on Wednesday in the Journal of the American Medical Association, researchers from the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Alcoholism, and the Medical Department at Brookhaven National Laboratory demonstrate that the radiation emitted by cell phones, at the very least, do affect the brain. Participants were exposed to a cell phone turned on in one ear for fifty minutes as well as a cell phone turned off in the opposite ear simultaneously. Examination of PET brain scans showed that areas of the brain that were close to the cell phone that was on had increased glucose metabolism and brain activity.
