The proliferation rates of HT-1080 human fibrosarcoma cells can be accelerated or inhibited by weak static and extremely low frequency magnetic fields

This in vitro study exposed HT-1080 human fibrosarcoma cells for 4 days to weak extremely low frequency magnetic fields (10 μT, 12–33 Hz) superimposed on a 45 μT static field. The authors report frequency- and amplitude-dependent increases or decreases in cell growth, including sharp inversions near 16.5 Hz with…

Exploring the influence of Schumann resonance and electromagnetic fields on bioelectricity and human health

This review examines links between extremely low-frequency electromagnetic fields, especially the Schumann resonance at ~7.83 Hz, and biological regulation of bioelectricity. It describes proposed mechanisms involving calcium flux modulation and downstream effects on neural activity (including EEG) and circadian…

Extremely low frequency magnetic field distracts zebrafish from a visual cognitive task

This animal study trained adult zebrafish to perform a conditioned avoidance response to a visual cue. The visual cue was presented alone or together with an extremely low frequency sinusoidally changing magnetic field (0.3 Hz) at 0.015 mT or 0.06 mT. The abstract reports that the 0.06 mT magnetic field condition…

Proteomic analysis in human fibroblasts by continuous exposure to extremely low-frequency electromagnetic fields.

This in vitro study examined whether continuous extremely low-frequency electromagnetic fields (3 Hz, 4 mT for 3 hours) alter protein expression in human fibroblast cells using proteomics. The authors report that some protein expressions differed between exposed and sham cells. They identify reduced expression (about…
