Photon Sucking as an Essential Principle of Biological Regulation

reabsorbed as soon as it is emitted or reemitted by the tissue under study. A typical example is displayed in Fig. 1. The first observations of “photon sucking” in living tissues can be traced back to the strange phenomenon of oscillations around the relaxation curve of delayed luminescence (Popp et al., 1981). After confirmation of these findings by Chwirot et al. (1987), Schamhart and van Wijk (1987) observed some kind of photon-induced photon absorption in normal cell cultures of sufficiently high cell density, whereas this effect disappeared completely in tumor cell cultures (Fig. 2). As shown by Scholz et al. (1988), these effects are strongly correlated with the degree of coherence of the reemitted photons (Fig. 3). An even deeper understanding of this phenomenon was provided by the dissertation of M. Galle
