New study shows plants and animals emit a visible light that expires at death

A new study reveals that both plants and animals emit a visible light that fades at the moment of death. This phenomenon, known as postmortem bioluminescence, was observed in organisms like zebrafish and Arabidopsis plants. The light emission was found to be associated with the oxidation of lipids in dying cells. Researchers hope to further investigate this process to potentially develop new tools for monitoring cell death in living organisms.
