>“It is amazing that sea turtles have access to a wealth of invisible information that they use to navigate in ways that are hard for us to even imagine.”

we can never hope to compete with nature, but i do find that statement funny. They literally built a device to help emulate turtle navigation. GPS is a part of life. Humans can detect and have found uses for almost every part of the spectrum. Compasses have existed for centuries. I'm not being dismissive of this discovery at all. I just find it remarkable how much we have managed to achieve.
