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!)
Mapping magnetite in the human brain
A nice find!
The two articles dovetail nicely.
