Living Beings Emit a Faint Light That Disappears at Death
Living organisms emit a faint glow through ultraweak photon emission, which ceases at death. This glow, linked to cellular activity and oxidative stress, could be used for non-invasive health monitoring, disease detection, and even searching for extraterrestrial life. Advances in imaging technology may soon enable real-time, field-deployable assessments of organism health and stress responses.
