Scientists are investigating the way birds use a photochemical compass to navigate the Mother Earth's weak magnetic fields in their migratory routes.

Apparently, birds use signals from chemical reactions sparked by the amount of sunlight and the earth's weak magnetic fields to guide them in their annual trips to go eat, poop, and bone in different parts of the world.

A version of this sweet chemical compass probably will be a feature on Google Maps eventually, along with colorful sperm robots.
