Biomechanist Katy Bowman and biologist Jeannette Loram take a deeper look into three recent headlines in the body-nerd world.
First up, recent research has shown that our skeletal muscles remember training at the protein level - no brain required! This is exciting research and Katy and Jeannette discuss the implications for exercise over the lifespan. Second, they dig into a recent study of uphill walking; the research suggests it is cheaper to take the steeper route, but energy efficiency might not be the only consideration. Finally in response to the online noise about recent changes to the CDC developmental guidelines, Katy and Jeannette explain what has really changed and whether it should have caused such an upset.

Cardiac Cowboys
The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
