The only biological effect that I know of that uses spin is the detection of the vertical component of Earth's magnetic field in bird eyes. [1] I don't think the effect has been reseached further (such as exposing birds to a very strong magnetic field and see if their perception is altered afterwards, not sure whether that would pass an ethics commitee..) The floating frogs were supposedly fine afterwards. [2] Supposedly, if any long term effects occur, they are subtle. There is a lot we do not know yet - for example, cells seem to be able to communicate through glass. (How? no clue. Photons have been proposed.)
