US researchers have done an experiment and, in a development, understood that the human body emits faint visible light that fades away gradually as the person approaches death. According to a discovery published in The Journal of Physical Chemistry Letters, this phenomenon is called ultraweak photon emission (UPE) or biophoton emission. All living organisms, including humans, mice and plants, emit an ultra-weak light that disappears upon death, says the study conducted by researchers from the University of Calgary and the National Research Council of Canada.

A report by Science Alert highlighted the research findings, as per which the light-emitting phenomenon revealed here is known as ultraweak photon emission (UPE) or biophoton emission. The study suggests that all living organisms on t
