The Fire Amoeba That Breaks Life’s Heat Limit

Listen for free

View show details

A microscopic hunter in a California hot spring is rewriting the temperature limit for complex life. In a geothermal creek that would scald a human, one amoeba still copies its DNA and splits in two.

This episode follows the discovery, why the old 60°C rule looked solid, what heat actually does to a cell, and why a few extra degrees change how we think about habitability—on Earth and maybe elsewhere.
