Weight-loss surgery successful in adolescentsBariatric surgery refers to several different surgical procedures designed to assist weight loss by limiting the amount of food someone eats or the amount they absorb during digestion. It has been used for several years to treat obesity in adults. A newly released study reported in the journal Clinical Obesity reveals that bariatric surgery can result in significant weight loss in severely obese adolescents.

Protecting the brain from epileptic seizures For years brain researchers have puzzled over the shadowy role played by the molecule putrescine, which always seems to be present in the brain following an epileptic seizure, but without a clear indication whether it was there to exacerbate brain damage that follows a seizure or protect the brain from it. A new Brown University study unmasks the molecule as squarely on the side of good: It seems to protect against seizures hours later.
