Telophase reorientation corrects errors in spindle orientation that persist after imprecise initial spindle positioning during early mitosis, and contributes to balancing self-renewal with differentiation during epidermal development.
The structure of the yeast RSC complex, a member of the SWI/SNF chromatin remodeling family, determined by cryo-electron microscopy, reveals a conserved structural core and the mode of nucleosome engagement.
Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
In neuronal mitophagy, Parkin and OPTN induce efficient sequestration of damaged somal mitochondria into autophagosomes, but slow turnover via lysosomal acidification may be a point of vulnerability for the cell.

MYC and Twist1 drive metastasis by a novel non-cell-autonomous transcriptional mechanism of eliciting a cytokinome that mediates the crosstalk between cancer cells and macrophages, and its therapeutic blockade inhibits metastasis.

Elucidation of the molecular basis of early wound epidermis dependence during salamander limb regeneration reveals midkine as a key modulator of wound epidermis development and wound-healing resolution.
Combining Organs-on-Chips technology with adult intestinal organoids provides an improved model of human duodenum and a new platform for preclinical drug assessment.
