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.
