Modeling analysis from the Global Dietary Database estimated that 70% of new global cases of type 2 diabetes are attributable to suboptimal intake of 11 dietary factors, with substantial differences in dietary risks across world regions and nations.

We reconstruct the spatial distribution and timing of wetland loss through conversion to seven human land uses between 1700 and 2020, elucidating the magnitude and land-use drivers of global wetland losses to improve assessments of wetland loss impacts.

Functional and structural characterization of PtmA2 reveals that it is an unusual non-adenylating acyl-CoA ligase and part of a system wherein the canonical acyl-CoA ligase reaction is separated into two half-reactions performed by distinct enzymes.

Newly evolved Xanthomonas citri pv. malvacearum isolates triggers recent bacterial blight outbreaks in cotton. Here, the authors show that a recently evolved TALE, Tal7b, activates host susceptibility genes GhSWEET14a and GhSWEET14b rather than GhSWEET10 to confer pathogenicity in these new isolates.

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).

An avian influenza virus of the H7N9 type, associated with live-poultry markets, has caused two human epidemics in China. Here, the authors develop a statistical model that predicts the risk of H7N9 infection in live-poultry markets across Asia, as a tool for disease surveillance and control.

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.

Estimates from the Global Dietary Database indicated that 2.2 million new type 2 diabetes and 1.2 million new cardiovascular disease cases were attributable to sugar-sweetened beverages worldwide in 2020, with the highest burdens in sub-Saharan Africa, Latin America and the Caribbean.

Afforestation and reforestation programs aimed at enhancing carbon sequestration may have unintended effects on non-forest ecosystems and biodiversity. Here the authors use remote sensing and land surface modelling to quantify trade-offs between tree planting and wetland conservation in China

Aegilops sharonensis is a wild diploid relative of wheat. Here, the authors assemble the genome of Ae. sharonensis and use the assembly as an aid to clone the Ae. sharonensis-derived stem rust resistance gene Sr62 in the allohexaploid genome of wheat.

Analysis of the hydrolysis kinetics of strigolactone receptors using enzyme-activated fluorescent probes revealed that the catalytic triad histidine of the receptor forms a covalent interaction with the strigolactone hydrolysis product, the D ring.

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.

Wearable sensors typically require innovative methods of energy harvesting for low-power electronics. Here, the authors present an adaptive power management system with a trimodal energy harvesting approach.

Although the role of the human diet in climate change has been widely acknowledged, current practices fail to capture its realistic effect on warming. In this Analysis, Ivanovich et al. develop a global food consumption emission inventory and estimate the associated future climate impact using a reduced-complexity climate model.

MultiSTAAR provides a general and flexible statistical framework for functionally informed multi-trait rare variant analysis of biobank-scale sequencing studies by jointly analyzing multiple traits and incorporating annotation information.

In flowering plants, hermaphroditism is widespread. Here the authors identified a transposon insertion that triggers plant sexual transition. This study highlights the role of transposons in plant adaptation and evolution.

A comprehensive map of genomic variation in melon derived from resequencing of 1,175 accessions sheds light on the population structure and domestication history of melon and agronomic traits for melon breeding.

Large-scale data on human mobility metrics have been used to gain insights into COVID-19 transmission dynamics, but best practices for use of these datasets have not been established. Here, the authors perform a systematic review to describe the sources of mobility data and methods used for analysis in the early COVID-19 pandemic.

Here the authors show genome-wide chromatin changes and transcriptional reprogramming occur in response to heat stress in tomato, leading to the transient formation of promoter-enhancer contacts to drive the expression of heat-stress responsive genes. Furthermore, they show chromatin spatial reorganization requires HSFA1a, a transcription factor (TF) essential for heat stress tolerance in tomato.

Using multi-ancestry genome-wide association study and fine-mapping, 298 loci and 36 credible genes are identified in the aetiology of bipolar disorder.

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.

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.

Analyses of genome and exome sequencing data identify rare coding and structural variants associated with atrial fibrillation and highlight genetic links between atrial fibrillation and cardiomyopathies.

Meta-analysis of genome-wide association studies on Alzheimer’s disease and related dementias identifies new loci and enables generation of a new genetic risk score associated with the risk of future Alzheimer’s disease and dementia.

We must mine the biodiversity in seed banks to help to overcome food shortages, urge Susan McCouch and colleagues.

Different functional variants in ADH1B (and elsewhere) in Europeans and Africans strongly affect risk for alcohol dependence. Dependence only partly genetically correlates with consumption, with strong correlations to other psychiatric disorders.

Non-homologous crossovers impair correct chromosome segregation in allopolyploids. Here the authors show that most non-homologous crossovers in Brassica napus arise from MSH4-dependent recombination and provide evidence that post-polyploidization reduction of MSH4 duplicate stabilizes meiosis.

Vaccination is effective in protecting from COVID-19. Here the authors report immune responses and breakthrough infections in twice-vaccinated patients receiving anti-TNF treatments for inflammatory bowel disease, and find dampened vaccine responses that implicate the need of adapted vaccination schedules for these patients.

Paul Pharoah and colleagues report the results of a large genome-wide association study of ovarian cancer. They identify new susceptibility loci for different epithelial ovarian cancer histotypes and use integrated analyses of genes and regulatory features at each locus to predict candidate susceptibility genes, including OBFC1.
