For centuries, the narwhal's spiraling tusk has occupied a strange border between myth and biology — sold as unicorn horn, admired by explorers, and never fully understood. Now, researchers using advanced three-dimensional X-ray imaging have mapped the tusk's internal architecture and revealed the mathematical principles that allow a single tooth to grow in a perfect helix without becoming brittle or unstable. The discovery is a reminder that nature often solves, quietly and over millennia, the very engineering problems that human ingenuity is only beginning to pose.
