Living Creatures Cast a Faint Aura That Stops at Death, Study Suggests

Living organisms, including humans, emit a faint glow that extinguishes after death.

Monitoring this weak signal could one day help scientists track injury and disease.

Researchers found that living things glow faintly throughout their lives due to the energy released by metabolic and cellular processes.

This light is extremely weak compared to ambient light sources and is hard to image.
