Pigeon study points to liver cells as a possible magnetic navigation sensor

Researchers say iron-containing immune cells in pigeon livers may help explain how birds detect Earth’s magnetic field, offering a new candidate mechanism for one of animal navigation’s longest-running mysteries.

Key Takeaways

Researchers identified iron-containing liver macrophages as a magnetoreception candidate.
The cells appear to sit near or contact nerve fibers.
