Mechanics of a heartbeat
(Top) The microtubule network in a heart cell at rest, as in diastole, and microtubules decorated with a fluorescent protein so they can be visualized with high-resolution microscopy. (Bottom) When compressed, as occurs during contraction systole, microtubules buckle and provide a spring-like ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Red Blood Cells Flowing Through Blood Vessel in Heart
This 3-D rendering of red blood cells flowing through a blood vessel in the heart to deliver oxygen to underlying muscle cells (myocytes) was created by researchers at the Pittsburgh Supercomputing Center (PSC) for PSC's Computational Modules in Science Teaching (CMIST) program. CMIST creates ...This is an NSF Multimedia Gallery item. (Source: NSF Multimedia Gallery)

Pathways to Prevention Workshop: Methods for Evaluating Natural Experiments in Obesity (Day 2)
Obesity is a major contributor to serious health conditions in children and adults. The prevalence of obesity in the United States and globally has grown rapidly in the last three decades; thus, there is a pressing need to help people achieve and maintain a healthy weight.
Obesity is commonly defined as having a body mass index (BMI) greater than or equal to 30. In 2014, more than one-third (37.7%) of U.S. adults (Flegal, 2016 ) and 17% of U.S. children and young adults under the age of 20 (Ogden, 2016 ) met this definition, accounting for about 55% of the total U.S. population. There are also persistent disparities among ...
