The ability to sense the Earth’s magnetic field—a trait known as magnetoreception — is well documented among many animals, but researchers have struggled to show that humans are also capable of the feat. Until now.
Despite recent panic surrounding the potential reversal of our planet’s magnetic poles, new evidence suggests it probably isn’t probably the impending doom it sounds like.
Earth’s magnetic field does way more than guide our compasses and cause occasional worry. It’s part of the reason there’s life at all on this planet — it protects us from harmful solar radiation that might otherwise blow our ozone layer away.
