The plus and minus of microtubules

Researchers have discovered how the chromosome-dividing spindle avoids slowdowns: congestion. A spindle comprises tens of thousands of microtubules connected by biological motors. Microtubules move forward only when linked to an anti-aligned neighbor. Previous experiments, however, showed microtubules cruising at full speed even when surrounded by neighbors with the same orientation. The researchers report that the microtubules are so entangled that even those not actively propelled forward get dragged along at top speed by the crowd.

The plus and minus of microtubules

Microtubules are protein polymers that assemble into dynamic structures, essential for cell division, shape, motility, and transport of intracellular cargos.
