  • Scientists suspect quantum effects are behind animals' ability to perform geomagnetic navigation.
  • Geomagnetic navigation is believed to be light-based.
  • Researchers watch as magnet-induced quantum changes affect cells' luminescence.

    • As dogs navigate, they appear to be using the Earth's magnetic fields.
    • 170 dogs orient themselves to north and south as they plot shortcuts back to their people.
    • Dogs join the growing number of magnetism-sensitive animals.

    Magnetic north isn’t even close to where it used to be

    You won't notice much of a difference unless you're north of the 55th parallel, though.

    • Magnetic north has recently been moving north from Canada to Russia in a cold hurry.
    • It's moving about 33 miles a year instead of the usual 7 miles.
    • World navigation models had to updated ahead of schedule to catch up with it.
