internal compass, how long a flu virus can last in the environment,

and whether creativity and mental illness actually go hand in hand.

Let's satisfy some curiosity.

Do humans have an internal compass? Think about it. Lots of

animals have an instinctive sense of which way points north. Even dogs tend to

poop in line with the planet's magnetic poles, really.

So then what about humans?

Especially those of us who never seem to be able to find where we parked our car.

Could we possibly have an internal compass? Well, it turns out the answer is probably yes.

And researchers even have some theories on how it works,

ranging from magnetite in our sinus bones to a protein called

cryptochrome. So for most of the 20th century, research

into the ability to sense magnetic fields or magneto reception were ridiculed. But scientists

have found that virtually every migratory animal, from birds to fish, have a built-in compass. So why not humans?

In the 1980s, British biologist Robin Baker performed experiments that suggested that humans had

magneto reception. But these results couldn't be replicated. And his claims of the human

sinus bone being magnetic were contested by Caltech geophysicist Joseph Kurshvink.
