To the naked eye, it is invisible, a nothing. Under the microscope, it seems a silvery corkscrew undulating on a darkfield. The form has a simple elegance, like the whorl of a nautilus shell or the sweep of a dragonfly wing. But that simplicity is an illusion. Through the more powerful electron microscope you see not a featureless wiggle but a shape-shifter―now a spiral, now a thread, now a rod or a sphere―with two walls, a dozen whiplike appendages and internal structures. And any microscope's view, revealed only indirectly, by laboratory tests, lies a marvel of complexities. The surface bristles with molecules that sense and respond to the environment, and the interior churns like a chemical factory. Inside, more than a thousand genes flicker on and off in changing sequences, to allow survival in places as different a a tick's gut, a dog's knee and a human brain.
