Sounds like a fun night out!
Dogs tend to align N/S before peeing.
I can in the northern hemisphere, but in the southern, I am all turned around.
Hmm, but why do they spin around three times before doing #2?
I can’t sense crap. I get lost in my back yard. I actually have asked for directions.
No crap , Einsteins. Humans and mother nature always have a connection.
If you blindfolded me and spun me around i can still sense magnetic north.
Ancient civilizations knew this info before these halfwit scientists we have today.
I can sense neutrinos passing through me. Also gravity waves generated by distant colliding black holes.
I can only detect Higgs bosons and tau neutrinos.
I can feel north some places but not others. I live in the mountains now and can’t feel direction an all here.
LOL
My dogs did no such thing.
It’s not just the brain that can ‘sense’ the Earth’s magnetic field. It’s the whole body. The answer to why is the same answer as to why Blood Cells are RED.
DG! I’ll see your Science news, and raise you one Physics Today! (for the record I sleep better West-East!)

Mapping magnetite in the human brain
The magnetic nanoparticles are concentrated primarily in the cerebellum and brain stem, among the oldest parts of the organ.
In 1992 researchers identified the presence of magnetite—a permanently magnetic form of iron oxide—in human brain tissue. Iron in the body was no surprise. It is commonly found in ferritin, an intracellular protein common to several organisms, and the magnetite was thought to have formed biogenically, with some possibly originating in ferritin. But the presence of magnetite in the brain could be more than incidental. Various studies have shown that brain cells respond to external magnetic fields. There’s also a disturbing link to neurodegenerative disease: Evidence exists of elevated levels of magnetite in brain tissue from Alzheimer’s disease patients. (More at link)
I had an MRI in in November its messed everything up.
Haven’t been able to find my way back to the Liquor store since! (Which may be just as well since they told me not to drink!)
Leftover stuff from our ‘birdbrain’... helps us fly to Mexico when the time is right.
