Single Atom Controls How Bacteria Walk

Bacteria can swim, propelling themselves through fluids using a whip-like extension called a flaggella. They can also walk, strolling along solid surfaces using little fibrous legs called pili. It is this motility that enable some pathogenic bacteria to establish the infections - such as meningitis - that cause their human hosts to get sick or even die.
