Abstract

We advance the hypothesis that biological systems utilize the geomagnetic field (GMF) for functional purposes by means of ion cyclotron resonance-like (ICR) mechanisms. Numerous ICR-designed experiments have demonstrated that living things are sensitive, in varying degrees, to magnetic fields that are equivalent to both changes in the general magnetostatic intensity of the GMF, as well as its temporal perturbations. We propose the existence of ICR-like cell regulation processes, homologous to the way that biochemical messengers alter the net biological state through competing processes of enhancement and inhibition. In like manner, combinations of different resonance frequencies all coupled to the same local magnetic field provide a unique means for cell regulation. Recent work on ultraweak ICR magnetic fields by Zhadin and others fits into our proposed framework if one assumes that cellular systems generate time-varying electric fields of the order 100 mV/cm with bandwidths that include relevant ICR frequencies.

Main findings

The paper advances a hypothesis that biological systems may utilize the geomagnetic field for functional purposes via ion cyclotron resonance-like mechanisms. It states that numerous ICR-designed experiments have demonstrated sensitivity of living things (to varying degrees) to magnetic fields equivalent to changes in geomagnetic field intensity and its temporal perturbations, and proposes an ICR-like framework for cell regulation.

Outcomes measured

cell regulation (hypothesized)
biological sensitivity to changes in geomagnetic field intensity
biological sensitivity to temporal perturbations of geomagnetic field
ion cyclotron resonance-like mechanisms (hypothesized)

Limitations

Hypothesis-based; no specific experimental methods or results are provided in the abstract.
Claims rely on unspecified 'numerous' experiments without details on design, exposure levels, or outcomes.
Key assumption (cellular time-varying electric fields ~100 mV/cm with relevant bandwidth) is stated as an assumption rather than demonstrated in the abstract.
