Model-inference reconstructed SARS-CoV-2 transmission dynamics in South Africa during March 2020 to February 2022, and quantified the immune erosion potential and transmissibility of three major variants (Beta, Delta, and Omicron), highlighting their common characteristics and the need for more proactive preparedness.

Multiple axonal guidance receptors control the local and selective translation of mRNAs by binding to ribosomes, specific mRNAs and RNA-binding proteins.

Correlative microscopy and electron cryo-tomography on apoptotic HeLa cells reveal remodeling of outer and inner mitochondrial membranes, Bax cluster ultrastructure and ATP synthase reorganization in ruptured mitochondria.

High-resolution imaging of microglia in zebrafish reveals a rate-limiting role for the centrosome in the engulfment of apoptotic neurons during brain development.

A droplet microfluidics approach to stably trap and phenotype individual micron-sized algae reveals their distinct but stereotyped movement patterns and how they respond in real time to local environmental cues, including novel boundary circling behaviour under strong confinement.

UV-reflective dragonfly wax is shown to consist of very long-chain methyl ketones and aldehydes, and a synthetic dragonfly wax spontaneously forms light-scattering fine structures with strong UV reflection.

Visual pigments with a longer peak-absorption wavelength or an open chromophore-binding pocket are generally noisier, being more prone to spontaneous activity.

TAF7L acts as a molecular switch that regulates the development of mesenchymal stem cells.

While flooding events may drive spillover transmission of Leptospira spp. through dispersal of the bacteria at low elevations, at higher elevations environmental risk is more localised and directly driven by the distribution of local rat reservoir populations.

Deep mutational scanning of a synthetic allosteric chimera revealed that a sparse set of mutations on the protein surface improved regulation.
