Fig.2 Increase of Delayed Luminescence of Tumor Cells with Increasing Cell Density Versus Decrease of Delayed Luminescence of Normal Cells. 3 Anomalous Absorption of Photons by Bacteria in Cell Culture Medium. Growing bacteria in culture medium which by oxidative reactions always emit light absorb from a definite density on the light of the medium. For higher densities this absorbance may decrease. 4 Interference-like Biophoton Emission from Daphnia in Dependence on the Population Density in Tap Water.
Daphnia display non-linear biophoton emission with increasing population density.
The minima and maxima can be assigned to definite mean values of their mutual distances in the population. This paper concerns the possible mechanisms behind these non-linear interactions between living systems and weak photon emission.
