Abstract
Lednev's (Citation) “possible mechanisms for the influence of weak magnetic fields on biological system” involved two parallel magnetic fields, one constant and one oscillatory in the ELF (extremely low-frequency) range. The suggested ion resonances (IPR) were termed “impossible” by Adair (CitationCitationCitation) even after they were demonstrated in a rat-nerve (PC-12) cell culture by Blackman et al. (Citation). The “signal-to-noise-ratio” paradox (introduced by the author) is resolved by taking account of the coherent absorption of the ELF energy and showing how the energy of several trillion ELF photons can free a single ion from its trap on the surface of a cell of the culture.
