Episode 435 - Cold war secrets and reanimating frozen life

June 14, 2021

Cold war secrets buried deep in the ice and forgotten, plus reanimating frozen life from Siberia. How could some frozen dirt, forgotten in a freezer for decades help us understand a future of rising sea levels? Greenland's name was a marketing stunt by Erik the Red, but it was once truly covered in greenery. Although Greenland is so close to the North Pole, all it's thick sheets of ice have completely melted (geologically) recently. How did scientists reanimate ancient animals buried in the Siberian Tundra? Rotifers can live in some unusual places, but they can also survive being frozen and brought back to life. Ancient animals have been 'unfrozen' and brought back to life though they are very small.
