  • Sabotaging Bacteria Propellers to Stop Infections
    When looking at bacteria, you typically see also flagella: long hairs that protrudes from the bacteria's body. The key function of the flagella is movement - what scientists call "motility." The flagella give the bacteria the ability to swim in their environment by rotating ...More
