Together with a companion paper, molecular details of immune responses in a pig-to-human xenotransplantation are identified through dense longitudinal multi-omics profiling of the xenograft and the host recipient, across the 61-day procedure.

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.

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.

A study reports whole-genome sequences for 490,640 participants from the UK Biobank and combines these data with phenotypic data to provide new insights into the relationship between human variation and sequence variation.

A genome-wide association study of critically ill patients with COVID-19 identifies genetic signals that relate to important host antiviral defence mechanisms and mediators of inflammatory organ damage that may be targeted by repurposing drug treatments.

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.

Interpreting untargeted mass spectrometry (MS) data is challenging due to incomplete reference libraries. Here, the authors created the nearest neighbor suspect spectral library from largescale public MS data, significantly enhancing the ability to hypothesize structures for unknown mass spectra.

Peatlands have historically acted as a carbon sink, but it is unclear how climate warming will affect this. The response of peatland carbon uptake to warming depends on the timing of summer warming; early warming leads to increased CO₂ uptake and later warming to decreased uptake.

Genetic and testing data from England show that the SARS-CoV-2 variant of concern B.1.1.7 has a transmission advantage over other lineages.

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.

A genome-wide association study performed in 1,126,563 individuals identifies seven new loci associated with Alzheimer’s disease and implicates microglia and immune cells in late-onset disease.

Metabolomics data from germ-free and specific-pathogen-free mice reveal effects of the microbiome on host chemistry, identifying conjugations of bile acids that are also enriched in patients with inflammatory bowel disease or cystic fibrosis.

The Omicron variant evades vaccine-induced neutralization but also fails to form syncytia, shows reduced replication in human lung cells and preferentially uses a TMPRSS2-independent cell entry pathway, which may contribute to enhanced replication in cells of the upper airway. Altered fusion and cell entry characteristics are linked to distinct regions of the Omicron spike protein.

Continuous monitoring of intraocular pressure remains a grand challenge in glaucoma care. Here the authors develop smart soft contact lenses for continuous 24-hour monitoring of intraocular pressure in human eyes, even during sleep.

The genome of a western lowland gorilla has been sequenced and analysed, completing the genome sequences of all great ape genera, and providing evidence for parallel accelerated evolution in chimpanzee, gorilla and human lineages at a number of loci.

Post-international travel quarantine has been widely implemented to mitigate SARS-CoV-2 transmission, but the impacts of such policies are unclear. Here, the authors used linked genomic and contact tracing data to assess the impacts of a 14-day quarantine on return to England in summer 2020.

In this study, Aggarwal and colleagues perform prospective sequencing of SARS-CoV-2 isolates derived from asymptomatic student screening and symptomatic testing of students and staff at the University of Cambridge. They identify important factors that contributed to within university transmission and onward spread into the wider community.

Repository-scale reanalysis of public mass spectrometry-based metabolomics data is facilitated by the Reanalysis of Data User (ReDU) interface, a system that uses consistent formatting and controlled vocabularies for metadata capture.

Feature-based molecular networking allows the generation of molecular networks for mass spectrometry data that can recognize isomers, incorporate relative quantification and integrate ion mobility data.

Genomics and metabolomics are widely used to explore specialized metabolite diversity. The Paired Omics Data Platform is a community initiative to systematically document links between metabolome and (meta)genome data, aiding identification of natural product biosynthetic origins and metabolite structures.

Electronic implants are often used in diagnosing and treating human illness, but permanent implants come with problems; here, devices are described that can sense temperature, pressure, pH or thermal characteristics, and—crucially—are fully resorbable by the body.

Imagine a future in which your garments are intelligent, expressive and transform the way you perceive and communicate with your environment. This is the promise of e-textiles. E-textiles could revolutionize healthcare, communication and our relationship with technology. However, their sustainable commercialization requires a comprehensive approach that involves scientific advancements and ethical and societal evaluation.

Sarah De Baets et al. investigate the effect of root hair abundance on root-substrate cohesion and experimental soil erosion in Arabidopsis. They find that plants with root hairs are more difficult to detach from soil and are better able to prevent soil erosion than root hairless plants and present a model to predict the impact of root hairs on soil erosion resistance.
