Science Fiction is only a few years away

The first paragraph and the rest of the ensuing article reads like a
medical science fiction novel but it is REAL. Its truly amazing what
these researchers are doing.

"Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy."
