In mice, the neural mechanisms underlying aversive social learning, specifically avoidance and fear after defeat, involve oxytocin signalling in the anterior subdivision of the ventromedial hypothalamus, ventrolateral part.

We study the interplay between cohesin and replication by reconstituting a functional replisome using purified proteins, showing how cohesin initially responds to replication and providing a molecular model for the establishment of sister chromatid cohesion.

Reconstruction of four Treponema pallidum genomes associated with human remains from around 2,000 years ago suggests that T. pallidum existed in the Americas and diverged to its modern subspecies before the fifteenth century European contact with the Americas.

Red mud is shown to yield green steel through fossil-free hydrogen-plasma-based reduction, a simple and fast method involving rapid liquid-state reduction, chemical partitioning, and density-driven and viscosity-driven separation.

High-speed molecular tracking is integrated with three-dimensional electron microscopy to map the diffusion distribution and ultrastructure of endoplasmic reticulum-mitochondria contact sites, revealing the ability of high-speed single-molecule imaging to map contact site interface structures and corresponding diffusion landscapes.
