New Amoeba Species Sets Record for Heat Tolerance in Complex Life

A groundbreaking discovery has revealed a tiny, single-celled organism capable of thriving in extreme heat, setting a new record for the heat tolerance of complex life forms. This newly identified species of amoeba can survive at temperatures that would prove lethal to all other known complex organisms.

Scientists detailed this remarkable finding in a study published in the journal Cell. The research highlights the amoeba's ability to eat and reproduce in hot spring water reaching an astonishing 63°C (145°F). This extreme environment is found within California's Lassen Volcanic National Park, where the organism was discovered.

Beyond its ability to thrive, the amoeba possesses a unique protective mechanism. It can safeguard itself against even higher temperatures, up to 70°C (158°F), by undergoing a transformation. This involves changing its shape and forming a resilient outer layer, effectively shielding its cellular structures from the intense heat.

The discovery offers significant insights into the limits of life and adaptation in extreme conditions. Its capacity to withstand and function in such high temperatures pushes the boundaries of what was previously understood about complex biological survival.

What to watch: Further research into the specific genetic and molecular mechanisms enabling this amoeba's extraordinary heat resistance.
