Nanoswarm: Invasion from Inner Space, a serious videogame adventure in healthy eating and exercise, has entered prototype testing. Game developer Archimage is collaborating with experts at the Children's Nutritional Research Center of Houston's Baylor College of Medicine on the project. The project is funded by a grant from the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health. The rising tide of childhood obesity has been linked to type II diabetes, a "looming crisis" that is reaching epidemic proportions. The Centers for Disease Control and Prevention predicts one third of Americans born after 2000 will be diabetic in their lifetime. Unlike type I diabetes, which is a result of mostly genetic factors, type II diabetes is primarily associated with diet and physical activity behavior. Diabetes is already the country's leading cause of new blindness and kidney failure. It is also the nation's sixth leading cause of death. Nanoswarm's rich, immersive, role-playing puts teenagers inside a videogame that blends sci-fi action and adventure with evidence-based behavior modification theories.
