A pooled analysis of longitudinal studies in low- and middle-income countries identifies the typical age of onset of linear growth faltering and investigates recurrent faltering in early life.

Understanding the emergence, evolution, and transmission of antibiotic resistance genes (ARGs) is essential to combat antimicrobial resistance. Here, Munk et al. analyse ARGs in hundreds of sewage samples from 101 countries and describe regional patterns, diverse genetic environments of common ARGs, and ARG-specific transmission patterns.

Small non-polymeric molecules have tremendous structural diversity that can be used to represent information. Here the authors encode data in synthesized libraries of Ugi products.

Dietary restriction promotes healthy brain aging, but the mechanism is unknown. Here, the authors show that OXR1 is upregulated by dietary restriction and confers age-related neuroprotection by maintaining retromer-mediated protein and lipid trafficking.

The goals, resources and design of the NHLBI Trans-Omics for Precision Medicine (TOPMed) programme are described, and analyses of rare variants detected in the first 53,831 samples provide insights into mutational processes and recent human evolutionary history.

An improved, fully re-annotated Aedes aegypti genome assembly (AaegL5) provides insights into the sex-determining M locus, chemosensory systems that help mosquitoes to hunt humans and loci involved in insecticide resistance and will help to generate intervention strategies to fight this deadly disease vector.

Detailed analyses pairing deep phenotyping and molecular profiles reveal mediating roles of plasma lipids in genetic and environmental factors associated with autism-related traits in children.

Many studies assess epigenetic marks in white blood cells, but it is unclear how much immune factors affect the epigenome. Here, the authors show that fine-scale blood cell composition and cytomegalovirus infection affect the DNA methylome of adults.

Trastuzumab binding to tumor cells depends on the availability of HER2 at the cell membrane. Here the authors show that caveolin-1 (CAV1) regulates HER2 density at the cell membranes and that CAV1 gene knockdown or protein depletion via the cholesterol modulator lovastatin, increases trastuzumab binding and anti-tumor activity.

The ambipolar field of Earth controls the structure of the polar ionosphere and boosts its scale height by 271%, physically driving  the polar wind and acting as the source of the magnetospheric cold H⁺ ion population.

A large-scale mutagenesis screen identifies mutant phenotypes for over 11,000 protein-coding genes in bacteria that had previously not been assigned a specific function.

Transient absorption with N prescribed excitation intensities allows isolation of N increasingly nonlinear responses, enabling separation of single- and multiple-exciton dynamics.

This study presents the results of the second round of the Critical Assessment of Metagenome Interpretation challenges (CAMI II), which is a community-driven effort for comprehensively benchmarking tools for metagenomics data analysis.

Rewetting of plant litter accumulated in dry riverbeds releases pulses of CO₂, reveals a global analysis of intermittent rivers and ephemeral streams.

Antibody-mediated SARS-CoV-2 uptake by monocytes and macrophages triggers inflammatory cell death that aborts the production of infectious virus but causes systemic inflammation that contributes to COVID-19 pathogenesis.

The interaction between land degradation and the livelihoods of the poor is complex and conditioned by important economic, social and environmental factors. These factors are also in part responsible for the limited success of economic growth policies to reduce poverty.

A survey of 136 factors that may influence cytokine secretion identify smoking, cytomegalovirus latent infection and body mass index as influential factors, with varying effects on innate and adaptive immunity.

A coupled knockdown-editing screen shows that CRISPR–Cas9 editing in human cells requires the Fanconi anemia pathway, which acts by diverting double-strand break repair away from non-homologous end joining toward single-strand template repair.

Exhaustion is an acquired state of T cell dysfunction. Sharpe and colleagues demonstrate that the phosphatase PTPN2 supports a T cell-intrinsic exhaustion program in both chronic infection and cancer models.

Antiviral nanoparticle-formulated mimics of heparan sulfate proteoglycans were developed and shown to permit strong viral association as well as inhibition of a range of viruses on in vitro and in vivo models of infection.

Leif Andersson and colleagues report the genome sequence of the ruff, a bird species with three male morphs with different reproductive strategies. Satellite and faeder morphs differ from the common independent morph by a 4.5-Mb inversion that occurred approximately 3.8 million years ago, and multiple genetic changes within this inverted region are associated with the satellite and faeder morphs.

Analyses of a long term fishery-independent trawl survey dataset reveal substantial loss of trawlable biomass and shift in community structure in a marine ecosystem, with little signs of recovery.

Exceptionally wet growing seasons, compared to the past 700 years, preceded the European Great Famine of 1315-1317 and are associated with a newly identified hydroclimate pattern, according to analyses of Europe-wide tree ring data.

Extensive flooding of the North American continent during the Cambrian occurred more recently and more rapidly than previously thought, according to analyses of detrital zircons sampled from the Grand Canyon region.

The authors defined a roadmap for investigating the genetic covariance between structural or functional brain phenotypes and risk for psychiatric disorders. Their proof-of-concept study using the largest available common variant data sets for schizophrenia and volumes of several (mainly subcortical) brain structures did not find evidence of genetic overlap.

Openshaw and colleagues find myeloid inflammation and complement activation signatures in patients with long COVID who were previously hospitalized.

Using genome-wide bisulfite sequencing of acute lymphoblastic leukemia subtypes, cell lines and healthy cells, Hetzel et. al. find that unlike most cancers, ALL has a highly methylated genome, which points to a distinct mode of epigenome regulation in this cancer type.

Liver diseases exert a substantial disease burden across the Asia–Pacific region. In this Review, the authors explore the epidemiological trends in the most common liver diseases in the region, including HBV infection, HCV infection and nonalcoholic fatty liver disease, and discuss implications for preventive measures.

Analysis of bronchoalveolar lavage fluid samples from patients with SARS-CoV-2-induced respiratory failure suggests that SARS-CoV-2 infects alveolar macrophages to cause release of T cell chemoattractants, thereby inducing local inflammatory cytokine release and further T cell activation, ultimately resulting in a positive feedback loop that drives alveolar inflammation.

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard model of particle physics, and does not show any signs of new physics, such as supersymmetry.

As phase 1 of the Earth Microbiome Project, analysis of 16S ribosomal RNA sequences from more than 27,000 environmental samples delivers a global picture of the basic structure and drivers of microbial distribution.

The number of publications in artificial intelligence (AI) has been increasing exponentially and staying on top of progress in the field is a challenging task. Krenn and colleagues model the evolution of the growing AI literature as a semantic network and use it to benchmark several machine learning methods that can predict promising research directions in AI.
