Parents shape whether their children learn to eat fruits and vegetables

Providing fruits for snacks and serving vegetables at dinner can shape a preschooler’s eating patterns for his or her lifetime. To combat the increasing problem of childhood obesity, researchers are studying how to get preschoolers to eat more fruits and vegetables. According to researchers at Washington University in St. Louis, one way is early home interventions — teaching parents how to create an environment where children reach for a banana instead of potato chips.

Brain tweak lets sleep-deprived flies stay sharp

Scientists testing sleep’s effects on learning have devised a model that presents fruit flies with a simple choice: fly into a lighted vial or a darkened one.Staying awake slows down our brains, scientists have long recognized. Mental performance is at its peak after sleep but inevitably trends downward throughout the day, and sleep deprivation only worsens these effects. For the first time, researchers at the School of Medicine have found a way to stop this downward slide. When scientists genetically tweaked a part of the brain involved in learning and memory in fruit flies, the flies were unimpaired even after being deprived of sleep.

New disease-fighting nanoparticles look like miniature pastries

Ultra-miniature bialy-shaped particles — called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City — could soon be carrying medicinal compounds through patients’ bloodstreams to tumors or atherosclerotic plaques. The nanobialys are an important addition to the stock of diagnostic and disease-fighting nanoparticles developed by researchers at the School of Medicine.

First U.S. incision-free procedure for obesity performed at Washington University

Christopher Eagon, M.D., performing the first TOGA procedure in the United States.Doctors at the School of Medicine have performed the first non-surgical procedure in the United States that restricts the size of the stomach to treat obesity. The investigational procedure was performed under direct endoscopic visualization with specialized instruments passed into the stomach through the mouth. The first U.S. patient received the treatment on July 23 at Barnes-Jewish Hospital in St. Louis.

Exercise could be the heart’s fountain of youth

Absence may make the heart grow fonder, but endurance exercise seems to make it younger. According to a study conducted at the School of Medicine, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts. The researchers also showed that by one metabolic measure, women benefited more than men from the training.
