    Evaluating the heat risk among city dwellers is important. Here, the authors assessed the heat risk in Philippine cities using remote sensing data and social-ecological indicators and found that the cities at high or very high risk are found in Metro Manila, where levels of heat hazard and exposure are high.

    Market integration may loosen the dense kinship networks maintaining high fertility among agriculturalists, but data are lacking. Here, Colleran shows that in 22 rural Polish communities, women’s ego networks are less kin-oriented, but not less dense, as market integration increases, potentially enabling low fertility values to spread.

    Spread of antimicrobial-resistant (AR) bacteria is a global concern, but contributing factors remain unclear. Here, authors analyze distribution of AR bacteria in households from three ethnic groups in Tanzania and find that livelihood factors are more strongly associated with AR prevalence than antibiotic use.

    Diabetic eye disease is a cause of preventable blindness and accurate and timely referral of patients with diabetic macular edema is important to start treatment. Here the authors present a deep learning model that can predict the presence of diabetic macular edema from color fundus photographs with superior specificity and positive predictive value compared to retinal specialists.

    Here, Nelson et al. use amplicon next-generation sequencing of two P. falciparum polymorphic gene regions to investigate the genetic similarity of parasite populations across time and space in a pediatric cohort in Kenya. They identify both micro- and macro-scale structuring of malaria parasites in this high-transmission setting, which could inform future intervention strategies.

    Invasive non-typhoidal Salmonella (iNTS) infections are dominated by antibiotic resistant isolates of the sequence type (ST) 313. Here, the authors identify the ST313 sublineage II.1 in the Democratic Republic of the Congo exhibiting extensive drug resistance and genetic signatures potentially associated with host adaptation.

    Antivenoms, obtained by venom immunization, have narrow species coverage due to low immunogenicity of venom neurotoxins. Here the authors immunize horses with a designed recombinant consensus neurotoxin, and the resulting antisera protect mice from envenomation by a broad spectrum of elapid snakes.

    Residential solid fuel use constitutes a large amount of air pollution but has been gradually replaced by other cleaner energy during the past three decades. Here the authors investigated the contribution of rural residential sector to ambient PM2.5 pollution and the resulting climate forcing and health impacts, and find that the remaining large quantities of solid fuels used in rural households are still a major contributor to ambient air pollution despite of decrease in its pollutant emissions and relative contribution to PM2.5 due to the clean energy transition.

    Type 2 diabetes (T2D) is prevalent in populations worldwide, however, mostly studied in European and mixed-ancestry populations. Here, the authors perform a genome-wide association study for T2D in over 5,000 sub-Saharan Africans and identify a locus, ZRANB3, that is specific for this population.

    Foreign aid is necessary to control tropical diseases in endemic countries. Here the authors outline the steps taken to control malaria in Africa since 2000 and present an economic model to propose that US$25−30 per capita will be needed to avoid a disease trap.

    There have been growing concerns about the exploitation of workers in the fisheries sectors. Here, Tickler et al. use a country-level metric of slavery to determine the risk of fisheries-level slavery across 20 countries, and find it rises as unreported catch increases and mean value of catch decreases.

    The decision when to stop an intervention is a critical component of parasite elimination programmes, but reliance on surveillance data alone can be inaccurate. Here, Michael et al. combine parasite transmission model predictions with disease survey data to more reliably determine when interventions can be stopped.

    Degradation—the loss of carbon stored in intact woodland—is very difficult to measure over large areas. Here, the authors show that carbon emissions from degradation in African woodlands greatly exceed those from deforestation, but are happening alongside widespread increases in biomass in remote areas.

    The rapid growth of South–South trade reflects a new phase of globalization. Here the authors show that some energy-intensive production activities, particularly raw materials and intermediate goods, and related CO2 emissions are relocating from China and India to other developing countries.

    Inundation and erosion could make many atoll islands uninhabitable over the next century. Here the authors present an analysis of change in the atoll nation of Tuvalu that shows a 2.9% increase in land area over the past four decades, with 74% of islands increasing in size, despite rising sea levels.
