Merged summary

TL;DR - A Nature article examines ultra-weak light emitted by living organisms and its potential biological uses. These “biophotons” might aid disease diagnosis or represent an undiscovered cellular signalling mechanism.

  • Living organisms emit extremely faint photons.
  • Emission patterns could potentially serve as disease biomarkers.
  • Cellular signalling via biophotons remains a hypothesis, not an established mechanism.
