If we could shrink a submarine down to the microscopic scale, could we pilot it into the human body to fight infection and perform surgery? Despite suggestions from futuristic sci-fi such as “Fantastic Voyage”, “Honey, I Shrunk the Kids”, “The Magic School Bus”, “Power Rangers”, and “Rick and Morty”, we cannot survive such shrinking and our vessel would be without a pilot. But it may still be possible to “shrink” down some of our technology and control it remotely as we will see from researchers at MIT in this week’s paper.
