The Safe Routes to School (SRTS) program was created as part of the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users, (SAFETEA-LU) in 2005. The US Congress initially authorized $612 million to facilitate the planning, development, and implementation of infrastructure improvements and other initiatives in and around schools to enable and encourage all children to walk and bicycle to school.

Sidewalks, bicycling infrastructure, and accessible trails and parks are just some of the features communities are seeking to encourage active living. While local and state funding is crucial, federal transportation funding is often a catalyst for improvements to the built environment.

Body Weight Simulator

Understanding the dynamics of human body weight change has important consequences for conditions such as obesity, diabetes, cardiovascular disease, starvation, and wasting syndromes such as anorexia nervosa and cancer cachexia. By using mathematical modeling to quantitatively integrate metabolism data with body weight and composition data, the Laboratory of Biological Modeling at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH) aims to substantially improve our understanding of body weight regulation and develop practical tools for research and clinical use.

One of these tools is a Body Weight Simulator, which helps us understand the impact of energy imbalance on body weight change.
