On the Move

Abstract

From the trafficking of intracellular cargoes to the flight of the wandering albatross, movement is one of life's central attributes. All organisms have a three-dimensional spatial context that is both internal and external; directed, organized motion, which creates as well as operates within this context, has been a prime target of natural selection from the dawn of evolutionary time. This special issue examines the principles of movement as expressed at scales ranging from the subcellular to that of individual organisms, and in robots as well as in living creatures.
