    "abstract": "The charges in live cells interact with or produce electric fields, which\nresults in enormous dielectric responses, flexoelectricity, and related\nphenomena. Here we report on a contraction of schizosacchraoymces pombe\n(fission yeast) cells induced by magnetic fields, as observed using a phase\nsensitive projection image technique. Unlike electric fields, magnetic fields\nonly act on moving charges. The observed behavior is quite remarkable, and may\nresult from a contractile Lorentz force acting on diamagnetic screening\ncurrents. This would indicate extremely high intracellular charge mobilities.\nBesides, we observed a large electro - optical response from fission yeast\ncells.",
