      This important study demonstrates that a peri-nuclear actomyosin network, present in some types of human cells, facilitates kinetochore-spindle attachment of chromosomes in unfavorable locations - thereby suppressing their missegregation rate. This actomyosin network and its general role have been studied previously, but this study convincingly clarifies the underlying mechanism using a light-controlled perturbation and detailed tracking of kinetochore movement. The generality of the mechanism could be further supported by confirming the findings in non-synchronized cells and additional cell lines. The results may have implications for understanding chromosome missegregation in cancer cells.
