Although only about 2% of Antarctica is exposed as ice-free land, there are hundreds of lakes found there that vary from freshwater to saline. There are even hundreds more that are below the ice sheets that have been hidden and isolated there for millions of years. In this episode, I review the different types of lakes found in Antarctica and the life within them. These lakes include the most saline lake on earth, Don Juan Pond which is 18x saltier than the ocean, and the most isolated lake in the world, Lake Vostok, a large freshwater lake that is 4 km below the ice sheet on the polar plateau.

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.
