Pigeons may ‘hear’ magnetic fields
Pigeons’ remarkable navigational feats have long been pegged to the birds’ ability to sense magnetic fields, but pinning down how they do so has frustrated scientists for years. Work published today in Science shows that individual cells seem to encode information on a magnetic field’s direction, intensity and polarity1. The work also suggests that these signals come from a part of the inner ear called the lagena, further complicating matters for researchers in the field.
