The Bacteria That Make Perfect, Tiny Magnets

Magnetotactic bacteria have built-in compasses that align with Earth's magnetic field, helping them navigate to optimal oxygen levels in water. These bacteria produce nanomagnets by forming magnetosomes with iron, which have potential applications in medicine and data storage. Bacteria are more efficient at creating uniform nanomagnets compared to chemical methods, offering insights into future technological advancements.
