German researchers exposed enzyme solutions and hemoglobin to millimeter wave radiation (40-115 GHz) at 10 mW/cm² to test for biological effects. They found no detectable changes in enzyme activity or oxygen binding, even with precise frequency scanning. This suggests millimeter waves at these intensities don't directly interfere with basic protein functions.

Researchers tested whether strong magnetic fields affect nerve signal transmission by exposing isolated lobster nerve tissue to a 1.2 Tesla magnetic field. They found no significant changes in nerve conduction velocity whether the field was applied parallel or perpendicular to the nerve.
