What Breaks a Cell’s Ribs Can Make It Stronger
TL;DR · WeSearch summary

The process of cell division exerts powerful forces on the cell's molecular machines, and researchers have been studying how these machines manage the strain. The mitotic spindle, a dynamic rib cage made of microtubules, plays a crucial role in cell division, and its ability to withstand forces without breaking apart has been a scientific mystery. Recent experiments have shown that the spindle has a self-repair mechanism that enables it to stabilize itself under force and avoid disintegrating.
