Living Organisms Emit Faint Light That Dims Upon Death
2025-05-19
Researchers at the University of Calgary have discovered that all living organisms emit a faint light, a phenomenon known as ultraweak photon emission (UPE). Studies on mice and plants revealed that living organisms exhibit significantly higher UPE intensity than deceased ones, with plant UPE varying based on stress factors like temperature changes, injury, and chemical treatments. UPE is linked to reactive oxygen species produced during cellular metabolism. This research suggests UPE imaging could become a non-invasive tool for both basic biological research and clinical diagnostics.
