## A microbe that thrives in fire
Scientists have discovered an amoeba that survives extreme heat, earning it the nickname fire amoeba.
## What makes it different
The fire amoeba is a eukaryote, a complex single-celled organism. Most eukaryotes cannot tolerate the temperatures this one endures.
## Pushing the boundaries
The discovery challenges scientists' understanding of where complex life can exist and survive on Earth.
## Expanding what's possible
Finding organisms that thrive in extreme conditions reshapes our knowledge of life's limits and potential habitats.
## New questions for science
The fire amoeba opens new research directions into how complex life adapts to hostile environments.
## Key takeaway

Researchers found a heat-resistant amoeba that expands the known boundaries of where complex life can exist on Earth.
