In humans, non-crossover gene conversion events transmit GC alleles in 68% of cases and exhibit a complex pattern of multiple disconnected tracts clustered within 20–30 kilobase intervals.

Trait-based metagenomic analysis of an ecosystem fertilization experiment shows that genomic traits that affect the costs and rates of biochemical information-processing mediate community assembly.

Diminished incidence of COVID-19 amongst healthcare workers in a comprehensive screening programme demonstrates how effective infection control measures and staff testing can prevent hospitals becoming independent 'hubs' of SARS-CoV-2 transmission.

The GC content of human mRNAs is key to P-body localization and protein yield, and has a major impact on their post-transcriptional control.

Variation in codon usage among functional categories of human genes is not due to selection for translation efficiency, but to differences in intragenic recombination rate, linked to variation in meiotic transcription level.

A paternal bias in germline mutation is seen throughout amniotes and may be explained by sex differences in DNA damage and repair after primordial germ cell specification.

In Thermoplasma acidophilum, an archaeon without histones, a DNA-binding protein acquired from bacteria via horizontal gene transfer mediates histone-like chromatin architecture.

An integrated cryoEM and X-ray crystallography study resolves the structural basis for antibody-mediated targeting of the hantavirus fusion glycoprotein and provides insight into the conformational landscape of the hantavirion surface.

Evolutionary analyses suggest that most mammalian circRNAs did not emerge from common ancestral circRNA precursors, arguing against widespread functional conservation.

Mutualistic viruses called virophages are common genome inhabitants of a marine protist, where they may protect host populations from giant viruses.
