As little as I care to associate with dogs, I have to love this:
When our planet’s magnetic field is quiet, dogs are more likely to do their business while standing along a north-south axis. Indeed, the data suggested that the animals were actively avoiding the east-west axis.
Apparently the sense which allows birds to navigate, using Earth’s magnetic field, also influences the position of Bowser and Fifi when they take a squat; during magnetic perturbation, they are less sure where to crap. (In case you were wondering, humans do harbor magnetically sensitive proteins — in our eyes, it seems — but I am not aware of specific research about human behavioral interaction with the magnetosphere. I can’t help thinking it must exist whether or not we are aware of it. We are all swimming in this EM soup.)
The original journal abstract is here, for the curious. “Frontiers in Zoology,” indeed.
