title: Cell signalling: changing shape changes the signal.
abstract: Recent experiments have revealed the existence of subcellular gradients of signalling molecules. A new modelling study shows that changes in cell shape or size allow gradient-controlled pathways to be turned on or off simply by altering the distance between the signal source and targets.
