I probably misunderstand your comment but electric potentials play many roles in biological functions (example: proton gradient). As for magnetism, it's certainly speculated that some migratory animals can detect the earth's magnetic field.

You can induce an activation potential with an external EM field. That’s the entire basis for deep brain stimulation.

A rediscovery is also a discovery. No need for the quotes here.

EDIT: Finding more evidence for convergence between scientific fields is also worthy. (Though the delta is very small at this point.)
