Some epidemiological investigations have suggested a link between exposure to radio frequency electromagnetic fields and risk of childhood leukaemia, but no one has yet suggested a plausible biological mechanism. Perhaps the results of a large case control study from Germany will lay the hypothesis to rest. Children living within 2 km of high powered amplitude modulated or frequency modulated radio or television transmitters were no more likely to develop leukaemia than those living more than 10 km away (American Journal of Epidemiology 2008;168:1169-78, doi:10.1093/aje/kwn230).

How parents talk to their adolescent children about sex, pregnancy, birth control, and sexually transmitted diseases affects the likelihood that adolescents will engage in risky sexual behaviours. A qualitative study finds, unsurprisingly, that when parents were receptive, informal, and composed during such conversations, adolescents were less anxious and less avoidant.
