Title:
Effects of Extremely Low Frequency Electromagnetic Fields on Growth and Differentiation of 'Physarum polycephalum'

Abstract:
Microplasmodia from the slime mold Physarum polycephalum have been continuously exposed to weak electromagnetic fields at 60 and 75 Hz. To date, microplasmodia have been exposed to field of 75 Hz, 2.0 G, 0.7 Vm for more than 700 days. Another set of cultures has been exposed to 60 Hz, 2.0 G, 0.7 Vm for more than 400 days. The time between successive mitotic divisions in cultures exposed to these fields varied from 0.5 to 2 hours longer than their respective controls. This delay was discernable after approximately 90 to 120 days of exposure to electromagnetic radiation. The ability to complete both the sexual sporulation or asexual spherulation life cycles was not affected but a retardation in reversible photoplasmic streaming was observed.
