AI Summary

Researchers at the Max Planck Institute for Neurobiology of Behavior used a novel brain‑mapping technique to examine how Ansell’s mole rat (Fukomys anselli) responds to magnetic field changes. The study found that when Earth’s magnetic field is dramatically reduced, the mole rats exhibit physiological signs of stress, indicating a strong reliance on magnetosensation for navigation. The animals, which navigate extensive underground tunnels with near‑blind eyes, appear to detect magnetic fields through those eyes, though the underlying mechanisms remain poorly understood.
