One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

Risk factors for SARS-CoV-2 infection in healthcare workers included caring for Covid-19 patients, Black or Asian ethnicity, and Covid-19-positive household contacts, whereas a bundle of PPE-related measures protected ICU staff.

New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

Spatial genomics reveals the mode of evolution of a tumour based on the positions of mutations in high-resolution samples.

Background selection is shown to be the dominant mode of linked selection in humans, with marked effects on diversity levels throughout autosomes.

Hamilton's rule can be violated when costs and benefits of cooperation are defined using the counterfactual method, and when they depend on the cooperation of others.

For many bacterial species, recombination dominates genome evolution and phylogenetic patterns that have so far been assumed to reflect clonal relationships, in fact reflect variation in recombination rates across lineages.

METTL3-mediated m6A modification maintains proper cell lineage specification during skin epithelium morphogenesis by coupling transcription and translation of key regulatory pathways.

Deciphering the mechanism of action of a large family of natural and synthetic cytotoxic lipids bioactivated by enantiospecific oxidation into protein-reactive species inspires the development of enzyme-specific prodrugs.

To make reliable but metabolically efficient perceptual inferences in a changing world, neural systems should dynamically adapt based on surprise and uncertainty about the sensory environment.
