A 71 THz signal was reportedly detected in living human cells and intact mitochondria

A reply says a September 2026 bioRxiv preprint by Shanghai researchers reports a 71 THz signal in living human cells, mouse tissues and intact mitochondria that disappears when structures are disrupted. The researchers hypothesize a quantum light-matter state in mitochondrial membranes that may help modulate ATP production. The reply also reports a roughly 10% boost with matching infrared light in lab tests and notes that the preprint had not been peer-reviewed.
