How do animals use magnetism to navigate ?

Scientists have been studying how some animals use magnetic navigation to find their way around.

While it has long been suspected that animals such as birds and fish possess some form of magnetic sense allowing them to travel large distances with impressive precision, the exact biological process through which this occurs has not been fully understood. This new study has helped researchers determine that some fish like trout have cells in their noses that act like a magnetic compass and enable the animals to find their way.

"Our results show that the magnetically identified cells clearly meet the physical requirements for a magnetoreceptor capable of rapidly detecting small changes in the external magnetic field," the research team reported.

"Trout have cells in their noses that act like miniature compasses to help them navigate, a study has shown."

A study was done that showed people have magnetic deposits in our brains ... right behind our noses. "follow your nose"

It must be pretty easy for a trout... most streams aren't that wide and it's either upstream or downstream...

Its a shame that if we did ever have this kind of ability that the lack of need for it over time has seen it be eroded away. Orienteering would be a lot easier if we instinctively knew which way north was. It must be pretty easy for a trout... most streams aren't that wide and it's either upstream or downstream... You are spot on Taun (once they are in fresh water ), but the difficult part for Trout is finding the estuary of the river they are looking for, that is when the navigation factor really comes into play (finding the river from the sea).

I wonder of birds around the LHC collider go around in circles.

I wonder of birds around the LHC collider go around in circles. Until they collide?

Until they collide? Until they collide? Ahh. the elusive bird particle.

Fascinating, that explains a lot! Thanks for posting

if tat were so then fish hooks would have magnets and make catching fish super easy but the magnet would rust sooo..

Some bacteria have built in compasses too... http://www.sciencedaily.com/releases/2008/12/081216201412.htm http://www.nature.com/scitable/knowledge/library/bacteria-that-synthesize-nano-sized-compasses-to-15669190

not much good if there in a reservoir lmao interesting none the less. Thanks.
