Cool scientific paper showing that humans can detect magnetic fields (if only unconsciously).

They set up the test subjects in a Faraday cage and measured detection of the magnetic fields by EEG - even if the person couldn't tell anything was going on, the EEG changed when exposed to the magnetic fields, but only in certain rotations/presentations.  

For example, when the field was aligned in a way that is naturally present in the Northern Hemisphere, the subjects (Northern Hemisphere residents) showed the EEG changes.  If the EM field was presented in a Southern Hemisphere alignment, they didn't have the EEG change.

Obvious control test: Do the same test with southern hemisphere residents.

It'll be interesting if things change, or not. Both give different clues to how human magnetoreception works.

Heh. My father always blames the way he poops out after dark on "electromagnetic rays from the sun." Which, technically, is true even as a simple response to the change in lighting, but still.
