Ion Cyclotron Resonance interactions in living systems

The interaction of weak magnetic fields, with intensities on the order of the geomagnetic field, is a very interesting subject that only recently, in the last few decades, has received much scientific attention. In the late 1970s a number of independent studies showed, counter to scientific prediction, that magnetic fields on the order of the geomagnetic field (GMF) appeared capable of interacting with living things. The first of these was the impressive data on bird sensitivity brought to the fore by husband-and-wife Wolfgang and Roswitha Wiltschko, by Beason and Semm, and by other ornithologists. Quite independently, an epidemiological study by Wertheimer and Leeper found that leukemia in children increased with proximity to the 60 Hz frequencies emitted by power lines, implicating magnetic intensities below 5µT, ten times less than maximum geomagnetic levels. Most critically, an experiment designed by Adey (Fig. 1) and Bawin studying radiofrequency effects on chick brain (Bawin et al, 1978), later modified by Blackman, discovered that calcium transport is profoundly affected when the radiofrequency was modulated by specific extremely low frequencies (ELF).
