Toads continue to amaze us - this time they are using their sense of the Earth's magnetic field to find their way home. But how important this sense is for cane toads as they travel home from long journeys, and how much are they relying on their sense of smell, was a mystery, until a clever new study tested the toads. Then we briefly touch on how pythons digest bones so successfully.
