Effects of Extremely Low Frequency Electromagnetic Fields on 'Physarum polycephalum'.

摘要

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.
