Devra Davis, of the University of Pittsburgh's Center for Environmental Oncology, has an interesting piece posted on YouTube on the possible health risks of cell phone use.  A health scare about cell phone use seems to appear every couple of years but changes no one's actual behavior as far as I can tell.  What is interesting about this short video is how sensibly it incorporates a discussion of risk into the question of the safety of cell phones. Should we stop using cell phones altogether?  No.  Should we think about the potential consequences of long-term microwave exposure to developing brains.  You bet.   

Food for thought, particularly on the subject of the appropriateness of cell phone use by children and adolescents.
