Splet31. mar. 2024 · To find out if the bacteria could actively control swarming, given the opportunity, the team set out to design a situation where a tendril encountered an obstacle that didn’t interfere with the flow of the liquid. After some experimentation, they landed on antibiotics. The team placed a drop of the antibiotic gentamicin near the tip of a tendril.
