What Magnetizing Cockroaches Can Teach Us About Navigation

A new study has found cockroaches can sense the Earth’s magnetic field, an ability called magnetoreception. Could humans have this sense, too?

“Kong and co placed a series of living and dead cockroaches in a magnetic field of 1.5 kiloGauss; that’s about 100 times stronger than a fridge magnet. The team left the creatures in the field for 20 minutes and then measured how strongly they had become magnetized and how long it took for this magnetization to decay.”

“Birds do it. Bees do it. But the human subject, standing here in a hoodie-can he do it? Joe Kirschvink is determined to find out. For decades, he has shown how critters across the animal kingdom navigate using magnetoreception, or a sense of Earth’s magnetic field.”

“Dolphins can now add magnetic sense to their already impressive resume of abilities, new research suggests. When researchers presented the brainy cetaceans with magnetized or unmagnetized objects, the dolphins swam more quickly toward the magnets, the new study found.”
