Animal Magnetism: How Animals Navigate

The video explores magnetoreception, the ability to detect magnetic fields, which is found in various animals. Initially, it was believed that animals navigated using celestial cues, but research in the 1950s revealed that birds might use magnetic fields. Studies suggest that animals like trout and birds have cells containing magnetite, aiding in navigation. Another theory involves cryptochrome in the eyes, which might allow animals, including humans, to perceive magnetic fields. The video highlights ongoing research and the potential for humans to have a similar sense.

What findings did the German researchers discover regarding the cells in trout's noses?

In what ways might humans also possess the ability to detect magnetic fields?
