Here, the authors conduct a paired genome analysis of humans and Mycobacterium tuberculosis in a cohort from Lima, Peru. Their research reveals that genetic variations in both the host and pathogen significantly influence the progression to tuberculosis.

Environmental sustainability movements have faced criticism for their often mechanical, anthropocentric approach that maintains standards of overconsumption within healthcare and has perpetuated planetary harm. Environmental stewardship, as practised within many Indigenous communities, instead focuses deeply on the interconnectedness of human and planetary health, and offers insights from which the health community can learn.

Joller and colleagues show that the co-inhibitory receptor TIGIT induces the expression of the tissue growth factor amphiregulin (Areg) in regulatory T cells and contributes to tissue repair in response to viral infection.

A high-resolution, global atlas of mortality of children under five years of age between 2000 and 2017 highlights subnational geographical inequalities in the distribution, rates and absolute counts of child deaths by age.

A study of several longitudinal birth cohorts and cross-sectional cohorts finds only moderate overlap in genetic variants between autism that is diagnosed earlier and that diagnosed later, so they may represent aetiologically different conditions.

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.

Naked mole-rats are long-lived rodents with remarkable resistance to cancer. Here authors show that their T-cell compartment is different from that of mice in that they have a large population of circulating cytotoxic γδ T cells harboring a dominant clonotype, and the clonotypic diversity of their conventional cytotoxic αβ T cells is more modest than that of mice.

In this work, the authors study the immunological and virological effects of administering either wild-type anti-HIV-1 broadly neutralizing antibodies (bNAbs) or bNAbs with a mutation that increases binding to Fc-gamma receptors (FcγRs) to rhesus macaques in the acute phase of SHIV_AD8-EO infection.

Head and neck squamous cell carcinoma (HNSCC) frequency and risk factors vary considerably across regions and ancestries. Here, the authors conduct a multi-ancestry genome-wide association study and fine mapping study of HNSCC subsites in cohorts from multiple continents, finding susceptibility and protective loci, gene-environment interactions, and gene variants related to immune response.

Fine-scale geospatial mapping of overweight and wasting (two components of the double burden of malnutrition) in 105 LMICs shows that overweight has increased from 5.2% in 2000 to 6.0% in children under 5 in 2017. Although overall wasting decreased over the same period, most countries are not on track to meet the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025.

High-throughput, single-copy sequencing of SARS-CoV-2 spike in a longitudinal cohort of people with and without HIV infection demonstrates striking intra-host diversity and adaptive evolution of SARS-CoV-2 in people with advanced HIV infection.

NAD⁺ is an essential cofactor in energy metabolism and redox reactions and is a regulator of different cellular processes. Kinetic and structural studies of the M. tuberculosis glutamine-dependent NAD⁺ synthetase suggests a tight coupling of the catalytic sites that catalyzes the ATP-dependent formation of NAD⁺ at the synthetase domain using the ammonia derived from the L-glutamine and glutaminase domain.

Neurons in the median preoptic nucleus that express the prostaglandin EP3 receptor produce prolonged hypothermic responses or hyperthermic responses, respectively, following brief activation or inhibition.

Study shows PTSD predisposition shares distinct genes and genomic regions with several cardiovascular conditions. Here the findings reveal neuronal, immune, and metabolic pathways, and repurposed drug targets that further the understanding of the comorbidity.

Passive immunisation for respiratory syncytial virus for infants is recommended by the World Health Organization but products currently available have limited duration of protection. Here, the authors investigate the age distribution of infant hospitalisation for respiratory syncytial virus to inform optimal timing of immunisation.

Authors perform an analysis of the patient data and risk factors to evaluate unfavorable outcomes and adverse events in adults with pulmonary tuberculosis treated with a 4-month rifapentine based regimen. Low rifapentine exposure was the most clinically significant risk factor for treatment failure and tuberculosis relapse.

Vaccines against the WA1 SARS-CoV2 strain confer protection against other variants. However, the mechanisms underlying cross-protection are not fully understood. Here, the authors develop a method for rapid analysis of single B cells from patient samples and show that infection with a variant elicits convergent, public B cell responses to other variants.

An analysis of 52 million births in 26 countries shows small reductions in preterm birth during the first to third months of lockdown. Further research is needed to examine causal pathways.

Buter et al. elucidated the biological function of the terpene nucleoside 1-TbAd, which is made abundantly by virulent but not avirulent Mycobacterium tuberculosis strains, and demonstrate that 1-TbAd regulates the pH and function of host macrophage endolysosomes.

Morgane Rolland and colleagues report that in HIV infection, a higher diversity of infecting founder viruses is associated with markers of poorer clinical outcome.

The bittersweet nightshade Solanum dulcamara produces extrafloral nectar from herbivore-inflicted wounds, without the need for any specialized structure. This nectar attracts ants that defend the plant against two of its native herbivores.

Springtails are omnipresent soil arthropods, vital for ecosystems. In the first global assessment of springtails, this study shows a 20-fold biomass difference between the tundra and the tropics, with distinct temperature-related patterns for diversity and metabolism that suggest climate change may restructure the functioning of soil biodiversity.

Determining progress in adaptation to climate change is challenging, yet critical as climate change impacts increase. A stocktake of the scientific literature on implemented adaptation now shows that adaptation is mostly fragmented and incremental, with evidence lacking for its impact on reducing risk.

The parabrachial nucleus contains separate populations of neurons that respond to elevated CO₂ with EEG arousal and increased breathing. Here we report that the parabrachial respiratory neurons express FoxP2 and are required for respiratory responses to elevated CO₂.

Analyses of the proportions of individuals who have completed key levels of schooling across all low- and middle-income countries from 2000 to 2017 reveal inequalities across countries as well as within populations.

High-resolution subnational mapping of child growth failure indicators for 105 low- and middle-income countries between 2000 and 2017 shows that, despite considerable progress, substantial geographical inequalities still exist in some countries.

Genetic diversity in social genes is expected to be shaped by conflict. Here, the authors show that in Dictyostelium discoideum, social genes in fact exhibit diversification patterns consistent with relaxed purifying selection, likely due to their expression only in intermittent social generations.

Bhattacharjee and Schaeffer et al. map exclusive breastfeeding (EBF) in 94 low- and middle-income countries (LMICs), finding increased EBF practice and reduced subnational variation across the majority of LMICs from 2000 to 2018. However, only six LMICs will meet WHO’s target of ≥70% EBF by 2030 nationally, and only three will achieve this in all districts.

Mathematical modelling of 15 years of data from South Africa reveals the spread and vaccine-driven changes in fitness and antimicrobial resistance of Streptococcus pneumoniae.

Although progress in the coverage of routine measles vaccination in children in low- and middle-income countries was made during 2000–2019, many countries remain far from the goal of 80% coverage in all districts by 2019.

Multi-ancestry genome-wide analyses identify 95 loci associated with post-traumatic stress disorder and implicate candidate genes, pathways and neurobiological systems underlying its pathophysiology.

Jones et al. examine the generalizability of the valence–dominance model of social judgements of faces in 41 countries across 11 world regions. They find evidence of both generalizability and variation, depending on the analytical method.

A gelling hypotonic solution for ocular delivery that forms a uniform and clear thin layer conformal to the ocular surface resists clearance from blinking and extends the residence time of the delivered drugs.

Chiea Chuen Khor, Tin Aung, Francesca Pasutto, Janey Wiggs and colleagues report a global genome-wide association study of exfoliation syndrome and a fine-mapping analysis of a previously identified disease-associated locus, LOXL1. They identify a rare protective variant in LOXL1 exclusive to the Japanese population and five new common variant susceptibility loci.
