Scientists at the University of Southeast Norway have released microorganisms into a Pac-Man-style maze made out of fluid to observe how the single-celled euglena (in this case, Pac-Man) avoid their predators, the multi-celled rotifers.


In addition to looking cool, these “micromazes” make it easier to view and study microorganisms, which are usually bunched together in a Petri dish. The Pac-Man imitation, though, was an inspired move on the part of the researchers, who wanted to better communicate their findings to the public.
