Illumination of thin liquid-crystal polymer films that contain azobenzene derivatives with short thermal relaxation times induces a continuous wave motion throughout the films, owing to a feedback loop driven by material self-shadowing.

Detailed micro-computed tomography analysis of the skull of Lethiscus stocki places it much earlier in the tetrapod lineage that was previously thought, showing that early tetrapods were more morphologically diverse than has been believed.

Analysis of a comprehensive database of mammalian host–virus relationships reveals that both the total number of viruses that infect a given species and the proportion likely to be zoonotic are predictable and that this enables identification of mammalian species and geographic locations where novel zoonoses are likely to be found.

The poxvirus vaccinia virus phosphorylates serine/threonine residues in the human small ribosomal subunit RACK1, converting it to a plant-like state to favour translation of poxvirus mRNAs

Epitopes derived from two regions of α-synuclein elicit immune responses in patients with Parkinson’s disease, involving IL-5-secreting CD4+ T cells, as well as IFNγ-secreting CD8+ cytotoxic T cells.

Prenatal immune suppression is regulated by fetal arginase-2-expressing dendritic cells which respond normally to toll-like receptor stimulation but, in contrast to adult dendritic cells, induce regulatory T cells and repress TNF-α secretion by effector T cells.

The inflammasome receptor Nlrp9b defends against enteric viruses by interacting with double-stranded viral RNA-bound helicase Dhx9, triggering gasdermin-D-dependent pyroptotic cell death of infected cells and secretion of Il-18.
