Here Yan et al. assess the community dynamics that are driving biodiversity-ecosystem function relationships across the world’s reef fishes. While reef fish abundances and species richness have similar impacts on productivity in temperate regions, productivity in the tropics is driven by abundances.

In a large, partially prospective cohort of patients with molecularly profiled and clinically annotated meningioma, the extent of surgical resection and radiotherapy (RT) response correlate with molecular classification, which can be used in a molecular model to predict clinical outcomes in response to RT.

Sears and colleagues found that ongoing replication stress pathways and T cell clonal responses differentiate liver and lung recurrence and are associated with different clinical outcomes in the context of pancreatic ductal adenocarcinoma.

A NutNet experiment in 57 grasslands across six continents shows that when herbivores are excluded from grasslands with a long coevolutionary history of grazing plant diversity is reduced, while in grasslands without a long grazing history the evolutionary history of the plant species regulates the response of plant diversity.

Evidence synthesized from 252 large-herbivore exclusion studies suggests that herbivore-induced change in dominance, independent of site productivity or precipitation, best predicts herbivore effects on biodiversity in grassland and savannah sites.

Inventory data from 90 lowland Amazonian forest plots and a phylogeny of 526 angiosperm genera were used to show that taxonomic and phylogenetic diversity are both predictive of wood productivity but not of biomass variation.

Homeostasis of memory T cells is modulated by each antigen encounter, thereby creating a heterogeneous population preventing precise tracking. Here, the authors use barcode-assisted tracing of Epstein-Barr virus-specific CD8⁺ memory T cells of young and older individuals to find antigen-guided, clonally divergent aging trajectories.

Glioblastoma (GBM) is an aggressive tumor characterized by an immunosuppressive microenvironment. Here, the authors present a therapeutic approach based on the implantation of a biodegradable scaffold for the sustained, local release of a TLR7/8 agonist at the time of tumor resection, to achieve anti-tumor immunity and protection from future tumor challenge.

A common but untested expectation is that nutrient enrichment causes biotic homogenization. However, a globally standardized nutrient addition experiment in grasslands shows proportionally similar species loss across scales and no biotic homogenization after up to 14 years of treatment.

In this work, authors report a mechanism for how phage can promote the spread of costly antibiotic resistance. They show that faster-growing sensitive cells dominate the biomass periphery where they encounter more phage, allowing for slower growing resistant cells to persist.

Different aspects of biodiversity may not necessarily converge in their response to climate change. Here, the authors investigate 25-year shifts in taxonomic, functional and phylogenetic diversity of tropical forests along a spatial climate gradient in West Africa, showing that drier forests are less stable than wetter forests.

An analysis of more than 500 sites distributed worldwide finds that declines in the abundance of terrestrial insects are attributable mainly to decreases in species that were formerly abundant, rather than being the result of losses of rare species.

Decadal averages of March precipitation in western Europe can be predicted by exploiting links with the jet stream and ocean along with skilful predictions of sea surface temperatures, according to an analysis of observations and reanalysis products.

Extended-spectrum cephalosporin resistance genes in Escherichia coli have spread worldwide. Here, the authors dissect the emergence and distribution of these genes over time, and across geographic location and host species, to better understand their dynamics and mechanisms of transmission.

The fossil taxon Propotto was originally identified as a primate, but is currently widely interpreted as a bat. Here, the authors identify Propotto as a stem chiromyiform lemur and, based on phylogenetic analysis, suggest two independent lemur colonizations of Madagascar.

Contaminant sequences in metagenomic samples can potentially impact the interpretation of findings reported in microbiome studies, especially in low biomass environments. Here the authors describe Squeegee, a computational approach designed to detect microbial contamination within low microbial biomass microbiomes and identify microbial contaminants in publicly available datasets that lack negative controls.

Ke et al. investigated the association between trauma exposure and post-traumatic stress disorder symptoms and the gut microbiome and dietary pattern of a cohort of women enrolled in a longitudinal study in the United States.

Chronic rhinosinusitis with nasal polyps generally has a type 2 inflammatory eosinophilic profile but can have a treatment resistant neutrophilic phenotype. Here the authors characterise nasal polyps using single cell sequencing and spatial transcriptomics and show granzyme K⁺CD8⁺ T cells associated with neutrophilic inflammation which promote release of neutrophilic chemoattractants from fibroblasts.

This protocol uses the R microeco package to provide a pipeline for the statistical analysis and visualization of microbiome data, covering omics data types such as amplicon sequencing data, metagenomic sequencing data and nontargeted metabolomics data.

An analysis of fish and macroinvertebrate communities in European rivers over 32 years shows that inland ship traffic is associated with declining taxonomic richness, diversity and trait richness and with increased taxonomic evenness.

The quark structure of the f₀(980) hadron is still unknown after 50 years of its discovery. Here, the CMS Collaboration reports a measurement of the elliptic flow of the f₀(980) state in proton-lead collisions at a nucleon-nucleon centre-of-mass energy of 8.16 TeV, providing strong evidence that the state is an ordinary meson.

Mixing metal-organic frameworks (MOFs) with halide salts enable low-temperature melting and processable MOF-derived glasses with tunable properties and enhanced structural versatility.

Poeck and colleagues identify a microbiome signature in patients receiving allogenic stem cell transplantation, which is associated with protective immune-modulatory metabolites, improved survival and less transplant-related mortality.

Authors perform a genomic analyses of 136 Klebsiella pneumoniae isolates, revealing that both the genetic background of host strains and the routes of plasmid transmission influence the spread of antimicrobial resistance in bloodstream infections.

Axonal injury, induced in the white matter by expansion of early tumour cells, is a key driver of glioblastoma progression.

Analysis of human genotypes and 16S microbiome data of 18,473 individuals from 25 cohorts through a genome-wide association study, a phenome-wide association study and Mendelian randomization identifies host genetic and microbial trait associations.

The enzyme ABHD18 is shown to have a key role in cardiolipin metabolism in mitochondria, offering a potential route for a small-molecule treatment of the rare genetic disease Barth syndrome.

Irritable bowel syndrome (IBS) is a complex and chronic gastrointestinal disorder associated with dysregulation of the gut-brain axis. Here, the authors develop an engineered microalgae that can address the pharmacokinetic complications of IBS and achieve the treatment of multi-organ symptoms.
