title: Intracellular transport: force controls motor switching at filament junctions.
abstract: How does cellular traffic switch direction on microtubules, or switch back and forth between microtubule- and actin-based tracks? A pair of recent studies mimics the layout of motors and tracks within the cell to provide intriguing answers to these questions.
