A remarkable discovery has been made in the world of microbiology: a single-celled organism, Incendiamoeba cascadensis, can thrive in extreme heat, pushing the boundaries of what was previously thought possible for eukaryotic life. This tiny amoeba, found in the unassuming hot stream of Lassen Volcanic National Park, can grow at an astonishing 63°C, surpassing the previous record for eukaryotic life by 3°C. But here's where it gets even more fascinating: even at 64°C, it continues to move and divide, and at 70°C, it forms dormant cysts that can reactivate when temperatures drop. This challenges the notion that eukaryotic life, which includes all animals and plants, is not suited to extreme conditions. Angela Oliverio, a microbiologist at Syracuse University, emphasizes the need to reconsider what's possible for eukaryotic cells in such harsh environments. The discovery, published in a preprint on November 24, has sparked excitement and curiosity among scientists, inviting further exploration of the potential for life in extreme conditions.
