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.

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.

Dimethyl fumarate (DMF) is an anti-inflammatory drug proposed as a treatment for COVID19. Here the results are reported from a randomised trial testing DMF treatment in 713 patients hospitalised with COVID-19. DMF was not associated with any improvement in day 5 outcomes.

Cortical activity can be monitored for 6 months or longer from within the brain vasculature using an endovascular stent-electrode array.

A machine learning algorithm can predict the future risk of idiopathic pulmonary fibrosis, a disease that is difficult to diagnose at its early stages, based on comorbidity signatures in electronic health records.

Formins promote the polymerization of actin filaments at barbed ends and capping protein prevents polymerization. Here the authors use single molecule imaging to directly visualize a decision complex consisting of the formin mDia1 and capping protein bound simultaneously to the filament barbed end and the dynamic mechanisms by which it forms and dissociates.

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.

The QT interval is a heritable electrocardiographic measure associated with arrhythmia risk when prolonged. Here, the authors used a series of genetic analyses to identify genetic loci, pathways, therapeutic targets, and relationships with cardiovascular disease.

Analysis of blood pressure data from the Million Veteran Program trans-ethnic cohort identifies common and rare variants, and genetically predicted gene expression across multiple tissues associated with systolic, diastolic and pulse pressure in over 775,000 individuals.

Computational analyses integrating whole-genome sequencing, cardiac epigenomic data and RNA-binding-protein data identify a role for noncoding de novo mutations in congenital heart disease.

Heart failure is a complex syndrome that is associated with many different underlying risk factors. Here, to increase power, the authors jointly analyse cases of heart failure of different aetiologies in a genome-wide association study and identify 11 loci of which ten had not been previously reported.

Sekar Kathiresan and colleagues examine 185 common variants using a modified mendelian randomization approach and provide evidence supporting a causal role of triglyceride-rich lipoproteins in the development of coronary artery disease.

Mangroves are adapted to cope with tropical storms, but might be threatened by rising frequency and intensity of these events. Here the authors document one of the largest mangrove diebacks on record following Hurricane Irma in Florida, and show a greater role of storm surge and ponding rather than wind as a mechanism for mangrove dieback.

On the electrocardiogram, the PR interval reflects conduction from the atria to ventricles and also serves as risk indicator of cardiovascular morbidity and mortality. Here, the authors perform genome-wide meta-analyses for PR interval in multiple ancestries and identify 141 previously unreported genetic loci.

Trans-ethnic analyses of exome array data identify new risk loci for type 2 diabetes. Fine-mapping analyses using genome-wide association data show that the index coding variants represent the likely causal variants at only a subset of these loci.

Surveys from 2,584 sites across the Indo-Pacific identify key climate, socioeconomic and environmental drivers associated with hard coral assemblages. This informs a strategic approach to protect, recover or transform coral reef management.

Breast cancer risk for BRCA1/BRCA2 mutation carriers varies depending on other genetic factors. Here, the authors perform a case-only genome-wide association study and highlight novel loci associated with breast cancer risk for BRCA1/BRCA2 mutation carriers.

Whole-genome sequencing analysis of individuals with primary immunodeficiency identifies new candidate disease-associated genes and shows how the interplay between genetic variants can explain the variable penetrance and complexity of the disease.

Climate threats to iconic places may arouse public concern and protective sentiment. This study shows that mass coral bleaching influenced sentiments, threat perceptions and values associated with the Great Barrier Reef and climate change attitudes in Australian and international tourists.

The Cas9-specific T cell response has been speculated to impair CRISPR therapy. Here, the authors show that local and systemic AAV CRISPR therapy induces cytotoxic killing and eliminates rescued dystrophin in canine models of Duchenne muscular dystrophy.

A global dataset of the satellite-tracked movements of pelagic sharks and fishing fleets show that sharks—and, in particular, commercially important species—have limited spatial refuge from fishing effort.

Assessing the conservation status of 1,020 European marine fishes reveals half of large (>1.5 m) fishes are threatened with extinction and stock status diverges geographically: almost all Mediterranean stock is overfished, most northern European stock is not.

Mary Relling and colleagues explore the effects of ancestry on the pharmacogenomics of relapse in acute lymphoblastic leukemia. They found that Native American ancestry was associated with risk of relapse but that differences in relapse risk were abrogated by the addition of a single extra phase of chemotherapy.

Upstream open reading frames (uORFs), located in 5’ untranslated regions, are regulators of downstream protein translation. Here, Whiffin et al. use the genomes of 15,708 individuals in the Genome Aggregation Database (gnomAD) to systematically assess the deleteriousness of variants creating or disrupting uORFs.

Protein Disulfide Isomerase (PDI) is a prothrombotic, multidomain enzyme with separate substrate binding and catalytic domains. Here, the authors identify a new class of compounds that target the PDI substrate binding site, inducing a conformational change in the catalytic domains and inhibiting thrombosis.

The relative importance of the mechanisms underlying species radiation remains unclear. Here, the authors combine reference genome assembly and population genetics analyses to show that neutral forces have contributed to the radiation of the most species-rich tree genus Syzygium.

The world’s tropical forests represent a terrestrial carbon sink, yet its size is uncertain. Espírito-Santo et al.characterize full Amazon disturbances combining forest inventories and remote sensing data, and use statistical modelling to quantify the Amazon aboveground forest carbon balance.

Capacitive energy storage is an attractive alternative to batteries, but electrochemical capacitors are limited by their low energy density. Oxygen vacancies are now shown to enhance the electrochemical properties of MoO_3−x.

Sun et al. report human lifespan changes in the brain’s functional connectome in 33,250 individuals, which highlights critical growth milestones and distinct maturation patterns and offers a normative reference for development, aging and diseases.
