Episode 336 - Life frozen in time inside extreme ice

July 22, 2019

Ice can be refreshing and cooling, but it can also be used to preserve life. Sometimes for strangely long periods of time. So just how do you make extreme forms of ice? From 'warm ice that doesn't ruin your frozen food, to controlled ice that helps planes fly. Sometimes you can even use a diamond to make some super controlled ice. Ice can harbour life even in some extreme conditions like the frozen and UV radiated Andes. Buried in Alaska is a bacterial community frozen in time. For 50,000 years bacteria have been thriving beneath layers of frozen tundra.
