wetwater 1 hour ago 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 ? refactor_master 1 hour ago > The researchers successfully tested the robots on phantom heart models that closely mimic a human heart, and on real porcine heart tissue. The robots traveled smoothly and autonomously, even against simulated blood flow.“In mice” - actually not even. ungreased0675 52 minutes ago 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.

raomin 4 hours ago if they manage to drive small robots, they could probably also drive magnetotactic bacteria...!https://en.wikipedia.org/wiki/Magnetotactic_bacteria

electric signal based actuators is catching up after machine learning boom
It was only a matter of time... https://www.youtube.com/watch?v=pRxfO7Fy0Yk
I for one welcome our magnetic millirobot overlords into my beating heart.
