Calcium cyclotron resonance and diatom mobility

Abstract

The hypothesis that movement of biological ions may be predicted by cyclotron resonance theory applied to cell membranes is tested in these experiments. Diatoms (Amphora coffeaeformis) were chosen as the biosystem since they move or don't move, depending on how much calcium is transported across the membrane. The experiments demonstrate that a particular ion (calcium) is apparently moved across the cell membrane in response to the DC and AC values of magnetic flux densities (B) and the frequency derived from the cyclotron resonance theory. A clear resonance is shown and a rather sharp frequency response curve is demonstrated. The experiments also show a dose response as the AC value of the flux density is varied, and that odd harmonics of the basic cyclotron frequency are also effective.

Main findings

Experiments in diatoms showed an apparent movement of calcium across the cell membrane in response to specific DC and AC magnetic flux densities and a frequency derived from cyclotron resonance theory. A clear resonance with a sharp frequency response curve was reported, along with a dose response as AC flux density varied and effects at odd harmonics of the basic cyclotron frequency.

Outcomes measured

• Diatom mobility (move vs. don't move)
• Calcium transport across the cell membrane
• Frequency response/resonance to applied magnetic fields
• Dose response to AC magnetic flux density
• Effectiveness of odd harmonics of cyclotron frequency

Limitations

• Sample size not reported in abstract
• Exposure parameters (exact flux densities and frequencies) not specified in abstract
• Experimental design details (controls, blinding, replication) not described in abstract

Suggested hubs

• elf-emf (0.62)
  Study involves DC and AC magnetic flux densities and cyclotron resonance-type frequency effects, consistent with low-frequency magnetic field exposure.
