Fully terrestrial life in Antarctica is extremely limited with only two flowering plants and no vertebrates (no polar bears!). Penguins and seals come ashore to breed or molt, but these are marine vertebrates. In this episode, I explore the plant and animal life in terrestrial environments in Antarctica. While limited to ice-free regions, there are hundreds of species of mosses and lichens. Invertebrates are limited to nematodes, springtails, mites and tardigrades that live in soils of different types and structure, including gelisols, or soils so dry they do not freeze as with permafrost, but remain loose. Ornithogenic, or bird-formed soils also are associated with penguin colonies and are rich in nutrients for more plant growth.

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.
