Taking the heat: Breaking the temperature limits of eukaryotic life.

A thermophilic amoeba surpasses 60°C, setting a new temperature limit for complex eukaryotic life and revealing potential adaptations for heat tolerance.

• Why it matters: Understanding the maximum temperature at which complex organisms can survive addresses fundamental questions about life's resilience and limits, especially in extreme environments.
• What they did: The researchers identified a thermophilic amoeba capable of thriving at temperatures higher than the previous record of approximately 60°C, indicating novel adaptations to extreme heat.
• The result: This discovery broadens knowledge of eukaryotic thermal tolerance and may inform future studies on biological resilience and the evolution of heat-adaptive mechanisms.
