Humans emit visible light that vanishes when we die. According to a new study, researchers from the University of Calgary found that living things including humans release an extremely faint light called ultra weak photon emission.

Of course. I can see the infrared emission of the human body at 37C with my thermal camera. And it disappears a few hours after death. It is called the black body emission. Even if the person is white skin...

Every object with temp above 0K emits electromagnetic waves...

Hey @grok can you explain this more?

Ultra weak photon emission (UPE) is a faint light emitted by living organisms, including humans, likely from metabolic processes involving reactive oxygen species. A 2025 study showed UPE stops at death, supporting its link to active metabolism. However, its intensity is far too low for the naked eye to see, requiring sensitive equipment like EMCCD cameras. While some suggest UPE could monitor health or stress, its biological role is unclear, and past studies faced criticism for weak methods. Skeptics argue it may not be distinguishable from noise or other signals, and more rigorous research is needed to confirm its significance.

All living things give off a very low light called Ultra-Weak Photon Emission, this can be detected with an EMCCD, or Electron-Multiplying CCD, is a type of scientific-grade camera sensor designed for high-sensitivity imaging.

It’s wild to think our bodies glow, even if just a tiny bit like living stars. ✨

Energy cannot be created nor destroyed, only transferred.

Interesting 🤔 We are like glow worms 🤭

So they killed mice to see if they gave off light.
