More than two decades ago, it has been proposed [1], that electric vibrations with frequencies in the GHz-region should be excited coherently in active biological material producing e.g. long range interactions of biomolecules.
In repetition of one result out of a series of russian experiments pointing to a verification of this theoretical conjecture, we have analysed the growth behaviour of single yeast cells by image cytometry and controlling the physical parameters by a high precision irradiation chamber. Frequencies round 42 GHz have been shown to influence cell growth (up to 10% to 20% ) in a resonance like manner, where the resonance width seems to be intensity dependent. These observations have been compared with results of model calculations of the response of nonlinear oscillators disturbed by external fields [2]. As a hypothesis to adapt this theory to our results, it is suggested, that a nonlinear selfsustained oscillator is involved in the biological response without, of course, any indication of the primary absorption process itself.
