December 9, 2013 Watching violent movies makes teenagers more aggressive, and that violence is almost always associated with sex, drinking and smoking. Violent characters in PG-13 movies are as likely to indulge in violent activities as those in R-rated flicks.
December 7, 2013 Earlier efforts to use gene therapy to treat a rare immune disorder in young children failed when some of the children got leukemia. Scientists say they think they may have figured it out, with eight children now living normal toddler lives.
December 4, 2013 For years doctors have been telling women that it's risky to implant multiple embryos when they do in vitro fertilization. They've listened, and the number of multiples from IVF has dropped. But the number of births of triplets or more has barely budged because of women's use of fertility drugs.
December 4, 2013 In a new poll, parents complain that their children are not getting nearly enough time for a basic school ritual: eating lunch. And that's worrying parents and administrators, given that about one-third of American kids are overweight or obese.
December 2, 2013 The polio outbreak in Syria has spread to four cities, and new cases are suspected each day. But U.N. agencies responsible for combating the outbreak can work only with the Syrian government. This limitation has hobbled vaccination efforts in rebel-held regions, where the virus was first detected.

November 25, 2013 Developmental psychologists are trying to figure out what very small children know and when they know it. The answer: a lot, and a lot earlier than you think.

November 22, 2013 The number of children diagnosed with attention deficit hyperactivity disorder has been rising since the 1990s. Now, the CDC reports that two-thirds of children with a current diagnosis are being medicated — a jump of 28 percent from 2007 to 2011.
November 22, 2013 When an Afghan toddler in Albuquerque was tested for lead at preschool, the child's blood levels were off the charts. A baby's brother's was, too. Why?

November 20, 2013 Around the world, children are slowing down. Researchers have found that kids don't run as fast as they did in the 1970s.
