We — and every organism around us — really do produce tiny amounts of light.
Scientists still aren’t sure whether these biophotons serve a purpose, or if they’re just cellular byproducts, according to Catalina Curceanu, a nuclear and quantum physicist.
It’s not bioluminescence, a well-known set of chemical reactions, notes Curceanu.
