MOLE-RATS. “The magnetic compass of mole-rats is affected by brief magnetic pulses with an intensity high enough to re-magnetize magnetite particles. The same properties were found for the magnetoreceptors of microphthalmic bats. Importantly, the magnetic compass of Ansell’s mole-rats was unaffected by a treatment specifically designed to perturb the radical pair mechanism using a RF field in the low MHz range (broadband as well as Larmor frequency, i.e., 1.315 MHz)16 over 300 times stronger than that shown to cause disorientation in birds.”
