History Alexander Gurwitsch around 1930Around 1923 Alexander Gurwitsch discovers an "ultraweak" photon emission from living systems (onions, yeast,...), since he suggested connections between photon emission and cell division rate. He calls this photonemission "mitogenetic radiation". His experiments indicate that the wavelength is in the range around 260 nm (Bibliography under ...
