Sounds like great weapon to assassinate someone.

Jokes apart, can anyone well versed actually tell of this is just a paper for publishing sake or is there any truth to this story ?

“In mice” - actually not even.

I think the researchers and I (and probably most other people) have a different definition of “autonomously”.

Not really, as your victim would also need to be in an MRI-like machine for fifteen minutes to an hour.

I do hope this is serious research as well. It’s hard to tell from the outside.

Even better, we can disguise it as a routine MRI scan

MRI sounds far from routine to me.

MRI is anything but routine.
