Before revision:  Tracking and fluorescence correlation spectroscopy revealed that in the cytoplasm, dynein spots displayed directed motions toward the cortex, localized at microtubule plus-ends through EBP-2 / EB but are not actively transported. Surprisingly CLIP-1/CLIP170 is not involved. ebp-2(0) slightly reduced spindle rocking, thus most cortical forcesremain suggesting a redundant mechanism .
