"We seem to be losing the battle to prevent childhood obesity by dealing with diet and exercise in individual children. Our study notes the interaction between environment and weight and suggests that environmental approaches to childhood obesity may prove more successful than working individually with the growing number of overweight children," said Gilbert Liu, M.D., assistant professor of pediatrics at the IU School of Medicine and a Regenstrief Institute, Inc. affiliated scientist, who is the principal investigator of the new study. The study relied upon patient data from the Regenstrief Medical Record System. Neighborhood vegetation and proximity to food retail were calculated using geographic information systems.
The study, which was conducted in Marion County, Indiana, found that increased green space was closely associated with decreased risk for being overweight, but only for children residing in higher population density regions. In more suburban areas, closer distance between a child’s home and the nearest major supermarket was more closely associated with decreased risk of being overweight than proximity of the home to green space.
The study authors hypothesize that being close to green space or to a grocery store affects weight by positively influencing physical activity and dietary behaviors. "As a pediatrician, I hope this study will encourage neighborhood organizations, community activists, and others to bring more opportunities for physical activities and healthy food choices to the places where children live," said Dr. Liu.

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
