Let me get this straight: * blood is made of iron * some blood cells are made for killing enemies * these defense cells also eat old blood cells, and become 🔮superparamagnetic🔮 et voila, magnetic navigation I love biology so much 😭😭😭 🧪
Researchers have identified superparamagnetic macrophages in the livers of rock pigeons to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. https://scim.ag/4nTQ3nq
