Here, using functional genomics and a new chromosome-level genome assembly of New Zealand possums, Bond et al. quantify their genome admixture and identify unique parent-specific and weaning associated gene expression.

Which combination of current genome sequencing and assembly approaches results in high-quality, complete diploid genome assemblies is determined.

Chronic infection with SARS-CoV-2 leads to the emergence of viral variants that show reduced susceptibility to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma.

Sera from vaccinated individuals and some monoclonal antibodies show a modest reduction in neutralizing activity against the B.1.1.7 variant of SARS-CoV-2; but the E484K substitution leads to a considerable loss of neutralizing activity.

Combination of epidemiology, preclinical models and ultradeep DNA profiling of clinical cohorts unpicks the inflammatory mechanism by which air pollution promotes lung cancer

FlyWire presents a neuronal wiring diagram of the whole fly brain with annotations for cell types, classes, nerves, hemilineages and predicted neurotransmitters, with data products and an open ecosystem to facilitate exploration and browsing.

Sequence assemblies for the genomes of 16 widely used inbred laboratory mouse strains highlight considerable strain-specific haplotype variation and allow for the identification of regions with the greatest sequence diversity between strains.

Whole-genome sequencing analysis of individuals with primary immunodeficiency identifies new candidate disease-associated genes and shows how the interplay between genetic variants can explain the variable penetrance and complexity of the disease.

A study of the evolution of the SARS-CoV-2 virus in England between September 2020 and June 2021 finds that interventions capable of containing previous variants were insufficient to stop the more transmissible Alpha and Delta variants.

John Chambers, Jaspal Kooner, Pim van der Harst, Shyong Tai, Paul Elliott, Jiang He, Norihiro Kato and colleagues performed a genome-wide association study of blood pressure phenotypes in individuals of European, East Asian and South Asian ancestry. They find trait-associated SNPs at 12 loci, some of which are associated with methylation at nearby CpG sites.

Catastrophic rock weakening upon impact of a meteorite, and hence flow, is shown to be followed by regained rock strength that enabled the formation of the peak ring during cratering.

The Vertebrate Genome Project has used an optimized pipeline to generate high-quality genome assemblies for sixteen species (representing all major vertebrate classes), which have led to new biological insights.

Investigation of variation in three cohorts has identified multiple genetic signals associated with the pregnancy-specific liver disorder, intrahepatic cholestasis of pregnancy, giving insight into the disease which can cause preterm birth and stillbirth.

A high-quality sequence assembly of the zebrafish genome reveals the largest gene set of any vertebrate and provides information on key genomic features, and comparison to the human reference genome shows that approximately 70% of human protein-coding genes have at least one clear zebrafish orthologue.

Trans-ethnic analyses of exome array data identify new risk loci for type 2 diabetes. Fine-mapping analyses using genome-wide association data show that the index coding variants represent the likely causal variants at only a subset of these loci.
