March 29, 2013 A government study of the medical records of 1,000 kids found no correlation between the number of vaccines a child received and his or her risk of autism spectrum disorder. Experts hope the finding will allay some parents who worry that many vaccines on one day or in the first two years of life may lead to autism.
March 26, 2013 Loneliness and isolation often go hand in hand, so teasing out which factor is harder on health isn't easy. But a British study now suggests that, while loneliness may make you unhappy, it's social isolation that could take years off of your life. Discuss (with a friend).
March 25, 2013 When abiding fear takes over some kids' lives, they respond with anger and aggression that's not premeditated. One psychiatrist says he's finding profound relief for a particular subgroup of these children in experimental research with the anesthesia drug ketamine.
February 12, 2013 A study of more than 85,000 women in Norway found that those who started taking a folic acid supplement four weeks before getting pregnant were about 40 percent less likely to have a child who developed the disorder.

January 9, 2013 An experimental drug developed to fight Alzheimer's disease partially reversed hearing loss caused by exposure to extremely loud sounds, researchers say. The results apply only to mice, but scientists are encouraged by the fact that the medicine caused new hair cells to grow in the animals' inner ears.
December 31, 2012 Superstorm Sandy is what most people will remember from the 2012 Atlantic hurricane season. But Sandy was just one of 10 hurricanes this year during a season that was both busy and strange. From an El Nino that never materialized to meandering tropical storms, meteorologists were baffled.
December 26, 2012 The year saw some disappointments in the development of drugs to treat Alzheimer's. But the setbacks were offset by progress in other areas.

December 21, 2012 Sandy Hook and other mass killings have left people wondering how someone could engage in such behavior. Scientists say that genes can indeed predispose a person to mental illness or violence. But genetic variants alone can't explain why someone commits mass murder.
November 19, 2012 A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. The new combination of genetic and health information is one of the most powerful research tools on earth, a researcher says.
