Norwegian scientists conduct research in a very special environment: a Pac-Man-like maze filled with a nutritious liquid, a few single-celled organisms and multicellular ‘ghosts’ that eat the single-celled organisms.
That may not sound sweet, but according to one of the professors, it is indeed a good way to set up research. In any case, better than research in a petri dish where all organisms tumble over each other. If it is such a ‘mountain’ of organisms, then studying becomes difficult. There is another way, thought the Norwegians of a college in southeastern Norway, namely in a Pac-man-like maze.
The unicellular cilia or Ciliophora are constantly attacked in the film by multicellular rotifers or Rotifera. The whole maze is no bigger than a millimeter in diameter, but luckily they used a microscope to film.
