Here the authors show in a large global study that participants that reported identifying more strongly with their nation reported greater engagement in public health behaviours and support for public health policies in the context of the pandemic.

Transcription factor osr2 is identified as a specific marker and regulator of mural lymphatic endothelial cell (muLEC) differentiation and maintenance, and muLECs and border-associated macrophages share functional analogies but are not homologous, providing an example of convergent evolution.

Genomic analyses applied to 14 childhood- and adult-onset psychiatric disorders identifies five underlying genomic factors that explain the majority of the genetic variance of the individual disorders.

As Nature Aging celebrates its fifth anniversary, the journal asks some of the researchers who contributed to the journal early on to reflect on the past and the future of aging and age-related disease research, the impact of the field on human health now and in the future, and what challenges need to be addressed to ensure sustained progress.

Cities are engines of innovation and economic growth, but they also struggle with segregation, which works against both. This study finds rings of isolation around US cities and pockets of segregation within them, a pattern persistent over time and intensified since the pandemic.

Fine-scale field analysis and modelling of the spatial dynamics of infection of Darwin’s frogs with Batrachochytrium dendrobatidis fungus identifies highly localized transmission dynamics that generate clustered epidemics and can drive collapse of local subpopulations.

Superconducting-qubit quantum annealers have served as platforms for simulating condensed-matter phenomena. Sathe et al. use a quantum annealer to probe critical phenomena in classical magnets by reliably sampling thermal distributions, revealing universal signatures of phase transitions without classical slowdowns.

Neural progenitor cell transplantation shows promise for treating spinal cord injury. However, here, the authors show that graft-derived neurons form limited synaptic connections with host spinal motor circuits after injury, constraining functional motor recovery.

Myeloid derived suppressor cells (MDSC) use different metabolic mechanisms to adapt to the tumour microenvironment. Here the authors show that 6-phosphogluconate dehydrogenase (6PGD) is important for MSDC function and that blockade of 6PGD impaired MDSC function and suppresses tumour growth leading to metabolic and functional changes in the MDSC and a more pro-inflammatory phenotype.

The combination of JWST and ALMA data here unravel the history of the gas content of a quiescent galaxy, which became quenched through an act of self-sabotage. Black-hole accretion feedback heated the galaxy’s surrounding material, preventing its accretion.

cellSTAAR advances noncoding rare variant association analysis by integrating single-cell genomics data.

The oncogenic potential of interfollicular stem and progenitor cells in cutaneous squamous cell carcinoma (cSCC) remains poorly understood. Here, the authors modelled rapidly growing cSCC driven by the hyperactivation of the MAPK signalling pathway in mice and showed that SOX2 overexpression renders progenitor cells prone to transformation.

High-resolution flare footpoint observations in the extreme ultraviolet and X-rays were taken by Solar Orbiter. Combined with simulations, the results reveal that the dominant mechanism carrying flare energy through the Sun’s atmosphere can vary on small spatial scales.

Mutations in GJB2 cause DFNB1, the most common hereditary deafness. ATAC-seq identification of gene regulatory elements enables targeted GJB2 delivery to cochlear cells, preventing hearing loss in mouse models.

HIV epidemic trends among female sex workers in sub-Saharan Africa are rarely known. The authors analyse HIV prevalence trends among female sex workers based in Zimbabwe and report a significant decline between 2016-2017 and 2021-2023, which may be due to increased treatment coverage among the male population.

Ghatbale et al. adapted a co-evolutionary technique to develop Klebsiella pneumoniae phages to be highly active longitudinally against K. pneumoniae clinical isolates, including drug resistant isolates.

Elevated levels of IL-33 induce the production of autoantibodies through an unknown mechanism. Here, the authors show that IL-33 disrupts splenic architecture and germinal center organization, causing an expansion of antibody-secreting plasmablasts and plasma cells. In multiple mouse models of inflammation, administration of IL-33 exacerbates the pathology, increasing the production of autoantibodies, whereas IL-33 blockade reverses autoantibody production in a model of lung inflammation.

Psoriasis is a difficult to treat chronic skin condition that could be limiting to quality of life. Here, authors present results of the phase 2 randomized clinical trial KNOCKOUT (NCT05283135) in which they treated patients with moderate-to-severe plaque psoriasis with higher-than-approved doses of risankizumab, an interleukin-23 inhibitor, to show high skin clearance rates and decreased tissue resident memory T cell numbers in the lesional skin.
