title: Molecular motors: Walking talking heads.
abstract: Small tension signals that pass between the two linked heads of kinesin allow the motor protein to coordinate its walking action. Two new studies suggest that certain members of the two other major families of motor proteins, the myosins and dyneins, can do the same thing.
