An in-depth analysis of tissue biopsies from patients with multiple myeloma and CAR T cell therapy-associated immune-related adverse events (CirAEs) after treatment with commercial BCMA-targeted CAR T cell therapy shows that CD4⁺ CAR T cells mediate off-tumor toxicities and that high CD4:CD8 ratio at apheresis, robust early CAR T cell expansion, ICANS and ciltacabtagene autoleuce treatment are independently associated with the development of CirAEs.

Here, the authors mapped the wastewater virome from 62 cities worldwide to identify over 2,500 viruses, revealing city-specific virome fingerprints and showing that wastewater metagenomics enables early detection of emerging viruses.

Amazonian fog samples contain viable microbes, suggesting fog plays a role microbial dispersal, colonization and nutrient cycling, according to analyses of fog samples from a tall tower observatory.

Microglia influence amyloid-β effects on astrocyte reactivity in the living brain of individuals with Alzheimer’s disease. This phenomenon further contributes to cognitive impairment via tau phosphorylation and aggregation.

Thirty years of forest demographic data, combined with recent ecophysiological measurements, reveal that intense Amazon droughts sharply increase tree mortality once soil moisture falls below a threshold, and that these hot droughts will become more frequent and intense as Earth warms towards hypertropical conditions.

Analysing >1,700 inventory plots from the Amazon Tree Diversity Network, the authors show that the majority of Amazon tree species can occupy floodplains and that patterns of species turnover are closely linked to regional flood patterns.

The non-coding RNA RNU4-2, which is highly expressed in the developing human brain, is identified as a syndromic neurodevelopmental disorder gene, and, using RNA sequencing, 5′ splice-site use is shown to be systematically disrupted in individuals with RNU4-2 variants.

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.

Fossils of Cretaceous birds with feathers are rare and known mostly from China. Here, the authors show an enantiornithine bird from the Lower Cretaceous of Brazil with a fully articulated skeleton and rachis-dominated tail feathers, which has implications for our understanding of feather evolution.

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).

This study shows that glial reactivity is linked to synaptic dysfunction in aging and Alzheimer’s disease, with tau pathology mediating these effects–highlighting the potential of synaptic biomarkers track disease progression.

The authors analyse tree responses to an extreme heat and drought event across South America to understand long-term climate resistance. While no more sensitive to this than previous lesser events, forests in drier climates showed the greatest impacts and thus vulnerability to climate extremes.

Wood density is a key control on tree biomass, and understanding its spatial variation improves estimates of forest carbon stock. Sullivan et al. measure >900 forest plots to quantify wood density and produce high resolution maps of its variation across South American tropical forests.

Head and neck squamous cell carcinoma (HNSCC) frequency and risk factors vary considerably across regions and ancestries. Here, the authors conduct a multi-ancestry genome-wide association study and fine mapping study of HNSCC subsites in cohorts from multiple continents, finding susceptibility and protective loci, gene-environment interactions, and gene variants related to immune response.

Tree mortality has been shown to be the dominant control on carbon storage in Amazon forests, but little is known of how and why Amazon forest trees die. Here the authors analyse a large Amazon-wide dataset, finding that fast-growing species face greater mortality risk, but that slower-growing individuals within a species are more likely to die, regardless of size.
