Abstract:

When the myxomycete Physarum polycephalum is exposed to sinusoidal 45, 60, 75 Hz or modulated 76 Hz electromagnetic fields, the mitotic cycle is lengthened, shuttle streaming period is slowed, and the rate of respiration is depressed. Further, modulated fields appear to induce these alterations sooner and at lower intensities than sinusoidal waves. The findings so far do not admit a conclusion that exposure to weak ELF electromagnetic fields is deleterious for Physarum or other organisms it can be concluded, however, that these fields do significantly affect biological processes.
