All living things, including humans, constantly emit a ghostly glow – and it appears to vanish almost as soon as we die. Monitoring this signal could one day help track forest health or even detect diseases in people.
The existence of this barely perceptible glow has been controversial, but it is thought to be the result of a process called ultraweak photon emission. Mitochondria and other energy-producing machinery in our cells involve molecules gaining and losing energy, in turn emitting the equivalent of a few photons a second per square centimetre of skin tissue.However, these “biophotons” are extremely difficult to detect and disentangle from other biological processes or light sources, such as the radiation produced by any warm object.Now, Dan Oblak at the University of Calgary in Canada and his colleagues have isolated what happens to these biophotons when an animal dies, imaging ultraweak photon emission across an entire mouse before and after its death.
The article is behind a paywall but it may be a legit report. Biophotons are a thing per wikipedia. I never heard of them but I am not surprised they exist. Biochemistry uses photons. It is a weak signal but it may be useful down the road. The idea of it was kinda creepy on first sight.
