A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

COVID-19 can be associated with neurological complications. Here the authors show that markers of brain injury, but not immune markers, are elevated in the blood of patients with COVID-19 both early and months after SARS-CoV-2 infection, particularly in those with brain dysfunction or neurological diagnoses.

Measurements from the heavily shielded Orion spacecraft during the uncrewed Artemis I mission show dose-rate reductions due to shielding and orientation for Van Allen belt crossings and quantify the interplanetary cosmic-ray radiation in a human-rated spacecraft.

A systematic census at 1,636 sites around Australia from 2008 to 2021 finds that more than 30% of shallow invertebrate species in cool latitudes exhibit a high extinction risk due to declining populations and oceanic barriers, but tropical coral species remain relatively stable.

Many SARS-CoV-2 infections may go undetected through conventional PCR or lateral flow tests. Here, the authors analyse the utility of analysing longitudinal nucleocapsid antibody trajectories to improve identification of prior SARS-CoV-2 infections using surveillance data from the UK.

Donor-specific antibodies in sensitized recipients may cause kidney transplant rejection. Here the authors show that complement component C3 inhibition prolongs graft survival by inhibiting T and B cell proliferation/activation and hence tissue injury, despite antibody levels remaining unaffected.

Mammalian genomes are scattered with repetitive sequences, but their biology remains largely elusive. Here, the authors show that transcription can initiate from short tandem repetitive sequences, and that genetic variants linked to human diseases are preferentially found at repeats with high transcription initiation level.

Estimates of infection rates from the UK COVID-19 Infection Survey may have been biased by the characteristics of people who chose to take part. Here, the authors show that the survey population had unusually high vaccination rates and adjust infection estimates taking this into account.

Spontaneous symmetry breaking and emergent polar order are key to liquid crystal phase behaviour. This study reveals two new polar liquid states with lamellar structures, providing novel insights into electrical analogues of magnetic spin structures.

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.

A case–control study investigating the causes of recent cases of acute hepatitis of unknown aetiology in 32 children identifies an association between adeno-associated virus infection and host genetics in disease susceptibility.

The factors influencing risk of reinfection with SARS-CoV-2 are poorly understood. Here, the authors use data from the UK COVID-19 Infection Survey, a community based longitudinal study, to assess characteristics of ~45,000 reinfections compared to initial infections.

A microfluidic bronchial-airway-on-a-chip lined by human bronchial-airway epithelium and pulmonary endothelium can be used to rapidly identify antiviral therapeutics and prophylactics with repurposing potential.

Integrating bioenergetic models and global coral reef fish community surveys, the authors show that there are functional trade-offs, meaning that no community can maximize all functions, and that dominant species underpin local functions, but their identity varies geographically.

Cellular nuisance compounds are a burden in chemical biology and drug screening. Here the authors profile prototypical cytotoxic and nuisance compounds using the cell painting assay to systematically characterise cellular morphologies associated with compound-dependent cellular injury and nuisance activity.

Openshaw and colleagues find myeloid inflammation and complement activation signatures in patients with long COVID who were previously hospitalized.

Longitudinal tracing of antibody responses to the ChAdOx1 and the BNT162b2 COVID-19 vaccines in 45,965 adults from the United Kingdom give indications for vaccine prioritization.

Halogen bond is desired for tuning electronic properties by external stimuli. Here, authors reveal a sequential activation of spin crossover and dimer softening, unveiling a key transient state in a prototypical halogen-bonded material.

Lean body mass is a highly heritable trait and is associated with various health conditions. Here, Kiel and colleagues perform a meta-analysis of genome-wide association studies for whole body lean body mass and find five novel genetic loci to be significantly associated.

Human norovirus pathogenesis is incompletely understood due to a lack of appropriate animal disease models. Here, Green et al. show norovirus replication in chromogranin A-positive enteroendocrine cells and other epithelial cells in tissue from a pediatric intestinal transplant recipient with severe gastroenteritis.

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

The impact of prior infection on the immune response to COVID-19 vaccination has not been fully characterised. Here, the authors use data from ~100,000 adults in the UK and find that a single vaccine dose in those with prior infection produces a comparable or stronger response to two doses in those without infection.

Analysis of whole-genome doubling (WGD) by using cancer sequencing data combined with simulations of tumor evolution suggests that there is negative selection against homozygous loss of essential genes before WGD but not after.

Most people who are infected with SARS-CoV-2 seroconvert within a few weeks, but the determinants and duration of the antibody response are not known. Here, the authors characterise these features of the immune response using data from a large representative community sample of the UK population.

A large study in the United Kingdom shows that virus-specific antibody levels associated with at least 67% protection against SARS-CoV-2 Delta variant infection last longer after two doses of BNT162b2 vaccine than after two doses of ChAdOx1 vaccine in previously uninfected individuals.

The duration and strength of protection against SARS-CoV-2 infection resulting from a booster vaccine dose or breakthrough infection are not well understood. This study uses data from the UK COVID-19 Infection Survey to investigate correlates of protection against Omicron BA.4/5 infection and assess antibody responses to booster vaccination and breakthrough infections.

Circulating tumour DNA profiling in early-stage non-small-cell lung cancer can be used to track single-nucleotide variants in plasma to predict lung cancer relapse and identify tumour subclones involved in the metastatic process.

Nanopore sequencing allows users to identify nucleotide sequence from ionic currents. Here, the authors use deep learning to facilitate the de novo identification of modified nucleotides, particularly methylated cytosine and guanine, from the measured ionic currents without the need for controls.

An international consortium reports the genomic sequence for ten Drosophila species, and compares them to two other previously published Drosophila species. These data are invaluable for drawing evolutionary conclusions across an entire phylogeny of species at once.

Pappalardi and colleagues identify a potent noncovalent DNMT1-selective inhibitor with improved tolerability and efficacy in preclinical AML models compared with clinically validated covalent pan-DNMT inhibitors.

Exome sequencing analysis of 13,933 individuals with bipolar disorder finds enrichment of ultra-rare protein-truncating variants in constrained genes. Combined analysis with schizophrenia exome data identifies AKAP11 as a risk gene for both disorders.

Pre-clinical studies have demonstrated the anti-tumor activity of selective inhibitors of CDK7, including samuraciclib. Here the authors report the results from dose escalation and two expansion cohorts in patients with breast cancer of a multi-modular Phase I clinical trial of samuraciclib as anti-cancer treatment.
