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).

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.

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.

Land-based mitigation for meeting the Paris climate target must consider the carbon cycle impacts of land-use change. Here the authors show that when bioenergy crops replace high carbon content ecosystems, forest-based mitigation could be more effective for CO₂ removal than bioenergy crops with carbon capture and storage.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

An integrated analysis of de novo and inherited coding variants in 42,607 individuals with autism spectrum disorder identifies 60 risk genes of which five have not previously been associated with neurodevelopmental disorders.

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.

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.

Zaman, Yang and Huang et al. demonstrate MDK’s suppressive effect on amyloid-β and its impact on amyloid burden and microglial activation in Alzheimer disease mice, highlighting its protective role in pathogenesis.

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.

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.

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.

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.

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.

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.

Whole-genome sequencing and phenotype data sharing are introduced in a national health system to streamline diagnosis and to discover coding and non-coding variants that cause rare diseases.

Culture profoundly influences the way a person engages with nature. As cities rapidly increase in cultural diversity, achieving universal equity in access to nature and the benefits that flow from it will depend on meaningful consideration of this diversity in urban design. Current approaches to urban planning and design tend to be implicitly monocultural, which may diminish equity of access and reproduce entrenched epistemological and material conditions that contribute to power imbalances and dictate whose preferences are reflected in urban nature spaces. To move toward culturally inclusive urban nature design demands explicit efforts be made in policy and practice to embrace the contextual, dynamic and multifaceted nature of culture and resist the implicit adoption of monocultural urban nature designs. We discuss the consequences of superficial cultural inclusion attempts and propose three key recommendations for taking a culturally-conscious approach towards urban nature equity.

An expert-elicitation process identifies current methodological barriers for monitoring terrestrial biodiversity, and how technological and procedural development of robotic and autonomous systems may contribute to overcoming these challenges.

Mirchandani and colleagues show that tissue hypoxia alters the number and phenotype of circulating monocytes and their differentiation into lung macrophages, with important implications for the resolution of inflammation in the lung.

Results from the Office of National Statistics COVID-19 Infection Survey in the United Kingdom demonstrate that the ChAdOx1 nCoV-19 and BNT162b2 vaccines reduce the incidence of new SARS-CoV-2 infections by up to 65% with a single dose and up to 80% after two doses, with no significant differences in efficacy observed between the two vaccines.
