Bacteria know that they are too small to make an impact individually. So they wait; they multiply, and then they engage in behaviors that are only successful when all cells participate in unison. There are hundreds of behaviors that bacteria carry out in such communities. Now researchers have discovered that bacteria form an unusual solitary wave - a behavior that has never been observed or described before in a living system.
