The phenomenon of non-chemical biological interactions (NCBI) was first discovered by Gurwitsch and later investigated in USSR, Europe, and USA (see Rahn, 1936; Gurwitsch, 1945). Gurwitsch’s group also showed that NCBI was mediated by ultraweak photon emission (UPE), and Rajewsky, Frank and Audubert were among the first who measured UPE (1931—1938). In 1950-s—60-s UPE from living objects was rediscovered and proved to originate mostly from lipid peroxidation (see Tarussov, 1972). The authors disputed against Gurwitsch’s NCBI, and argued that UPE was a mere side effect of oxidative processes. At present the interrelation of these two phenomena remains dim, and although some works on NCBI appeared recently, it is still not widely appreciated. How can UPE of 10—100 cps mediate NCBI? Frank (1931) suggested that UPE had a special temporal order. This view is getting recently an increased support. We demonstrate that UPE of frog eggs consists of single flashes, no longer than 1 millisecond each, which altogether occupy <1% of total time, and give 0,6—7 cps in average. As shown by Fourier analysis, they have a non-periodic stage-specific temporal order. An extensive burst of UPE flashes coincides with the period of activation of zygotic genes.
