Scientists discover 'fire amoeba' that thrives at record-breaking temperatures

In a laboratory, scientists have identified a microscopic organism — the fire amoeba — that reproduces at 145°F and moves at 147°F, temperatures that should, by every prior understanding, be lethal to complex life. This single-celled eukaryote does not merely survive at the edge of what biology permits; it thrives there, shattering the previous heat tolerance record for organisms of its kind by a meaningful margin. The discovery invites us to reconsider not only the boundaries of life on Earth, but the very maps we use to search for it elsewhere.
