Non-invasive strategies to detect and track activated myeloid cells will facilitate disease diagnosis and monitoring in patients affected by neuroinflammatory disorders. Here, the authors present 18F-FMD, a dendrimer-based PET tracer that detects and monitors activated myeloid cells at different stages (presymptomatic and symptomatic) of Experimental Autoimmune Encephalomyelitis (EAE) in mice and in response to disease-modifying therapies.

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease, but it is not deterministic. Here, the authors show that common genetic variation changes how APOE-ε4 influences cognition.

Using 63 globally distributed grassland and shrubland sites from the International Drought Experiment, this study identified plant traits linked to drought resistance after 1 year of extreme drought across growth forms, lifespans and climate.

In 2025, chemistry education research moved towards more mature and critical uses of generative artificial intelligence (GenAI). Recent studies show how GenAI can support visualization and learning of abstract chemical concepts, while highlighting the need for strong AI literacy to manage errors, ethics and misuse.

A controlled greenhouse study that manipulated the presence of both ectomycorrhizal fungi and arbuscular mycorrhizal fungi at a range of conspecific and heterospecific plant competitor densities shows that arbuscular mycorrhizal fungi promote plant species coexistence by equalizing fitness differences and stabilizing competition.

When senescent cells accumulate during adulthood they negatively influence lifespan and promote age-dependent changes in several organs; clearance of these cells delayed tumorigenesis in mice and attenuated age-related deterioration of several organs without overt side effects, suggesting that the therapeutic removal of senescent cells may be able to extend healthy lifespan.

Estimates from the Global Burden of Disease study reveal declines in chronic respiratory disease mortality between 1990 and 2023—especially during the COVID-19 pandemic—but the burdens on people affected remain substantial.

The CMS Collaboration reports the measurement of the spin, parity, and charge conjugation properties of all-charm tetraquarks, exotic fleeting particles formed in proton–proton collisions at the Large Hadron Collider.

Targeting neurons that regulate energy balance may offer new approaches for obesity treatment. Here, authors show that chemogenetic and pharmacological manipulation of GABAergic neurons in the DRN/vlPAG increases adaptive thermogenesis and reduces weight gain in mice fed a highfat diet.

In a phase 1b/2 trial, an off-the-shelf vaccine using gorilla adenoviral and modified vaccinia Ankara vectors with over 200 mutated peptides known to be present in persons with mismatch-repair-deficient tumors is safe and elicits neoantigen-specific T cells in individuals with Lynch syndrome.

Using metatranscriptomics of diatom-associated viruses and quantification of extracellular viruses in coastal water samples, the authors link silicon limitation to increased virus-induced mortality of diatoms, which could have implications for marine biogeochemical cycling.

Improved vaccines and antivirals are needed for many enveloped viruses. Here, the authors identify sulfur-based small molecules that disrupt viral membrane properties, inhibiting fusion and entry, and safely inactivate influenza virus. The resulting inactivated influenza vaccine is protective in mice.

This study shows that high-molecular weight tau has enhanced seeding capacity, and seeding differences can define molecular subtypes of progressive supranuclear palsy, underpinning the disease’s heterogeneity.

The tolerogenic activity of type 1 conventional dendritic cells (cDC1s) is determined by EPOR, which is preferentially expressed in cDC1s and induces antigen-specific FOXP3-expressing regulatory T cells.

The authors report a trial subset analysis of the immune responses induced by two inactivated quadrivalent influenza vaccines (QIVs): Sinovac QIV and Vaxigrip-Tetra™. Both vaccines elicit robust humoral responses and distinct T cell profiles.

Neutrophils infiltrate glioblastomas with the capacity to engage pro/anti tumoural responses. Here the authors developed proteomic workflows to stratify neutrophil heterogeneity by function. This work provides a platform to study neutrophil proteomes with single cell resolution in glioblastoma.

Barcoding microbial ribosomal RNA creates a recording of gene transfer events without requiring translation.

Walmsley and colleagues report that systemic hypoxia induces persistent loss of histone H3K4me3 marks and epigenetic reprogramming in neutrophil progenitors, resulting in long-term impairment of subsequent neutrophil effector functions.

Building flexible electronic devices demands an understanding of how mechanical deformation affects the active materials. Here, the authors observe and quantify the effects of local strains generated by the wrinkling instability in the conducting channel of rubrene crystal thin-film transistors.

Kalia et al. investigate metabolic changes in Alzheimer’s disease (AD) using blood metabolomics, and show that lysophosphatidylcholines are associated with early amyloidosis in AD as measured by P-tau181 and P-tau217.

Beck et al. develop a model where striosomes create a flexible “decision-space” that adapts to environmental context and internal state. It explains how we make choices and why decision-making varies between people, and in neuropsychiatric disorders.

PD-L2 can bind the immune checkpoint PD-1. However, its potential as a therapeutic target for immune checkpoint blockade in cancer has not been extensively explored. Here, the authors demonstrate that αPD-L2 is effective in aged, but not young, melanoma murine models.

Genotype and exome sequencing of 150,000 participants and whole-genome sequencing of 9,950 selected individuals recruited into the Mexico City Prospective Study constitute a valuable, publicly available resource of non-European sequencing data.

Antimicrobial resistance genes that have been mobilized between bacterial species represent a subset of the naturally occurring resistome. Here, the authors compare the abundance, diversity and geographical patterns of acquired resistance genes with latent resistance genes in global sewage metagenomes.

The role of the complement system (CS) - part of the immune system - in pancreatic ductal adenocarcinoma (PDAC) remains underexplored. Here, the authors evaluate the association of genetic variants in CS-related genes with PDAC risk, and explore their potential role in prognosis and immune infiltration.

CCR5-deficient gamma–delta CD19 CAR T cells show resistance to HIV-mediated depletion and antitumour efficacy in B cell malignancies.

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.

In this work, authors show that the nucleoside prodrug obeldesivir has potent antiviral activity across respiratory syncytial virus (RSV) clinical isolates with a high resistance barrier. Once-daily obeldesivir treatment was efficacious against RSV in a non-human primate model.

Einstein's theory of general relativity has been tested — and confirmed — on scales far beyond those of our Solar System. But the results don't exclude all alternative theories of gravity.

Variations in shield-derived sediment influx and weathering extent affect the Nd isotopic composition of North Atlantic seawater and seafloor sediments, according to Nd isotopic data from southwest Greenland.

Near-term climate prediction is an information tool used in climate adaptation services. This study analyses the quality of the predictions, showing that near-term climate forecasts have good skill in predicting temperature at regional scales, where most of the skill is attributed to atmospheric composition changes.

Vertebra lengths differ from the neck to the tail tip and differ between species, evidenced by extreme differences in mouse and jerboa tails. Here, Weber and colleagues identify cellular mechanisms and candidate genes that shape vertebral proportion.
