A structure-based model of the chromosomal cohesin complex, accompanied by molecular-mechanistic simulations, explains cohesin's key role in topologically entrapping DNA, as well as its ability to alternatively extrude DNA loops.
Slow-cycling chondrocytes are maintained in a Wnt-inhibitory environment within the resting zone, unraveling a novel mechanism regulating maintenance and differentiation of parathyroid hormone-related protein (PTHrP)-expressing skeletal stem cells of the postnatal growth plate.

The E2F/Dp transcription factors, which are key cell cycle regulators, can also mediate the regulation of carbohydrate metabolism in larva by controlling both systemic trehalose homeostasis and fat storage.
Descending interneurons maintain synaptic connectivity and behavioral function despite pruning during metamorphosis, showing that synaptic specificity is established twice at different life stages.

The cryo-EM structures of XKR9 define the architecture and caspase-mediated activation of a protein family that is involved in the exposure of phosphatidylserine during apoptosis leading to the engulfment of apoptotic cells by macrophages.

Single-molecule methods reveal that cytidine triphosphate promotes DNA condensation specifically at bacterial centromeres by facilitating one-dimensional diffusion of ParB from parS sites.

Synaptic resolution analysis of a full olfactory connectome reveals lateralised circuits, convergence of innate and learned pathways, and shows that homologous neurons are highly stereotyped within and across brains.
