Other than a magnetar, are there any sources of magnetism that will kill you directly (ie: not by accelerating some external object)?

What is the mechanism of removal of the proteins associated with Alzeheimer's?

I know there's been work with ultrasound that helps therapeutic drugs cross the blood-brain barrier - Is your work related to this or something else entirely?

Thanks!

That's really fascinating, thanks!

Are there any potential complications associated with the ultrasound process? From how you described it (exerting a mechanical force onto the blood vessels), it sounds like there's potential for damage to the blood-brain barrier or brain tissue itself.
