An expert on exercise physiology discusses the importance of different elements of fitness, and teenagers share personal stories about how exercise helped them achieve and maintain a healthy weight. Exercise also helps build strength, develop endurance, improve agility, boost self-confidence, and connect socially. John Ratey, a professor of psychiatry, describes the growing evidence that aerobic exercise remodels our brains, making us sharper mentally, and providing protection against mood disorders.

For nearly 40 years, Dr. Ellen Ketterson and her research team from Indiana University have been studying juncos in the mountain forests of Virginia. This segment introduces viewers to the junco, the researchers, and the core methods they use to study birds. Set in field, lab, and aviary locations, one landmark study is highlighted in detail: a long-term field experiment investigating the complex effects of the hormone testosterone on behavior, physiology, and evolutionary fitness. Part of Ordinary Extraordinary Junco (Chapter 2).
Mobile computing is accelerating beyond the smartphone era. Today, people wear smart glasses, smart watches, and fitness devices, and they carry smartphones, tablets, and laptops. In a decade, the very same people are likely to wear or carry tens of wireless devices and interact with the Internet and computing infrastructure in markedly different ways. Computer scientist Xia Zhou is working to make sure there are no traffic jams with the increased demand. With support from the National Science Foundation, Zhou and her team at Dartmouth College are developing ways to encode and transmit all that data faster and more securely. Part of the "Science Nation" series.
