Swimming without brains and muscles

Bacteria and other unicellular organisms developed sophisticated ways to actively navigate their way, despite being comparably simple structures. To reveal these mechanisms, researchers used oil droplets as a model for biological microswimmers. Biologists investigated the navigation strategies of microswimmers in several studies: how they navigate against the current in narrow channels, how they mutually affect their movement, and how they collectively start rotating in order to move.
