When the Light Goes Out

 Scientists find that living cells emit light—until death extinguishes it.

A surprising new study reveals that living human cells naturally emit a faint glow of visible light, the result of biochemical reactions within the mitochondria that produce tiny amounts of photons.

This subtle bioluminescence, invisible to the naked eye but detectable with sensitive instruments, appears to be closely tied to the cell’s metabolic activity and vitality.

Remarkably, researchers observed that this light fades and vanishes entirely when the cell dies, suggesting a potential link between this glow and the essence of life itself.

The discovery could open new doors in medical diagnostics and deepen our understanding of what defines living versus non-living matter.
