Air-pollution-derived magnetic nanoparticles found in human brains
Magnetite, a magnetic iron oxide mineral, is showing up in a place it doesn’t belong: the brain.
Researchers at the University of Lancaster found unexpectedly high levels of magnetite nanoparticles in human brain tissue they were examining with electron microscopy (Proc. Natl. Acad. Sci. USA 2016, DOI: 10.1073/pnas.1605941113). Barbara A. Maher, one of the team leaders, says that’s concerning because magnetite could . . .
