Blood donor serosurveillance in eight of Brazil’s most populous cities reveals extensive variation of SARS-CoV-2 attack rate across cities, age, and sex groups in December 2020 and increased intrinsic severity of the Gamma variant of concern.

Experimentally validated structural models of ACKR1-LukE and CCR5-LukE complexes reveal the critical contributions of sulfotyrosine binding sites and divergent loops of Staphylococcus aureus leukotoxins to the recognition of chemokine receptors.

The impact of changing gene expression noise on fitness reveals beneficial or deleterious effects in a stable environment depending how close the average expression level is to the fitness optimum.

Competition between adhesive and tensile forces regulates axon fasciculation, thus introducing a new role of mechanical tension in the development of neural networks.

One minute biotinylation with APEX2 peroxidase in living cells identifies established and new components of mitochondrial and ER membranes; dataset intersection and overexpression screen identifies SYNJ2BP overexpression as inducing mitochondria-rough ER contacts.

Visualized odor encounters show that Drosophila navigate spatiotemporally complex odor plumes using random walks biased by the timing of brief and unpredictable odor encounters.

The nonsense-mediated RNA decay (NMD) branch-specific factor UPF3B influences olfactory sensory neuron cell populations, the olfactory receptor repertoire, and antimicrobial gene expression.

Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.
