When we first heard about researchers using tiny freely floating tools to grab tissue samples deep inside the body, we were scared.
But our fears quickly turned to fascination.
Johns Hopkins engineers are testing out what they call "untethered microgrippers" as a better way to investigate hard-to-reach places. They have launched hundreds of these things, which look like miniature ninja throwing stars, inside the body of animal to retrieve tiny pieces of tissue for biopsies.
