MAGNETITE. “The existence of magnetite crystal chains, which lead to a magnetically oriented swimming behavior in so-called “magnetotactic bacteria”, unequivocally proves that living cells can, in principle, synthesize magnetite that will align with the geomagnetic field. However, the magnetite crystals in these bacteria are not part of an active sensory system; they only lead to passive alignment.”
