Lucy HicksRats and mice aren’t the only ones who can solve lab mazes. A new study suggests single-celled organisms—and even individual cancer cells—are just as adept, using chemical signals to find their way through complex mazes hundreds of times their size.Individual cells, whether cancer cells, skin cells, or single-celled organisms like bacteria, generally know where to go by sensing attractive chemicals in their environments and moving toward them, a process called chemotaxis.

This basic type of navigation works best for short distances, generally less than half a millimeter. But when cells traverse longer, more complex paths, they can’t just passively follow a chemical gradient: They need to process the chemicals around them in real.
