In the heart of Antarctica’s McMurdo Dry Valleys, a glacier bleeds. Known as Blood Falls, this crimson cascade has puzzled explorers and scientists for over a century. Is it algae, iron, or something stranger? Beneath the ice lies a hidden brine, a frozen laboratory where life endures without sunlight or oxygen — and where the boundaries of survival are tested.
In this episode of The Tilted Planet Podcast, Jack explores the surreal landscape of Blood Falls, from its discovery in 1911 to the cutting-edge science that reveals its secrets today. Along the way, you’ll meet the microbes thriving in isolation, uncover the chemistry that makes a glacier bleed, and reflect on what this alien place can teach us about life on other worlds.
Tilt your perspective and step into one of Earth’s strangest and most haunting wonders!

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.
