Birds Use Quantum Mechanics to See Magnetic Fields, New Research Suggests
Many birds have a sixth sense. No, not seeing dead people: They detect Earth’s magnetic field, an ability that allows them to return to the same sites, year after year, during seasonal migration. Now, scientists have come closer to identifying the mechanism that our feathery friends use to feel Earth’s magnetic field — and it…

Scientists Are Building A Mini-Earth With 8 Tonnes Of Spinning Liquid Sodium
Admit it, you don’t really understand why the Earth has a magnetic field. Sure, movement inside the Earth’s outer core is creating a electric current, generating a magnetic field through it. But what’s causing this movement?

This Company Uses Earth’s Magnetic Field To See Inside Buildings
In some ways, it’s an ominous pitch. By measuring the “magnetic fingerprint” of any building in the world, the Finnish company IndoorAtlas can conjure up a startlingly precise indoor map of any building. It’s technology that sci-fi has dreamt of for decades. But instead of surveillance, it’s being used for shopping.
