The response to infectious and inflammatory challenges differs among people but the reasons for this are poorly understood. Here the authors explore the impact of variables such as age, sex, and the capacity for controlling inflammation and maintaining immunocompetence, linking this capacity to favourable health outcomes and lifespan.

Over half the world’s rivers dry periodically, yet little is known about the biological communities in dry riverbeds. This study examines biodiversity across 84 non-perennial rivers in 19 countries using DNA metabarcoding. It finds that nutrient availability, climate and biotic interactions influence the biodiversity of these dry environments.

Corticosteroid therapy is frequently used for chronic obstructive pulmonary disease (COPD) but its use is associated with increased risk of pneumonia. Here the authors show that corticosteroid use impairs innate and adaptive immunity to rhinovirus infection, which is restored by exogenous IFNβ.

A cell-based phenotypic screen led to the discovery of compounds called NVS-STGs, which bind to the N-terminal domain of STING and act as a molecular glue to induce higher-order oligomerization and activation.

Data collected from more than 2,000 taxa provide an unparalleled opportunity to quantify how extreme wildfires affect biodiversity, revealing that the largest effects on plants and animals were in areas with frequent or recent past fires and within extensively burnt areas.

Spintronic nano-neurons and synapses can be connected by radiofrequency signals into neural networks that are capable of classifying real-world radiofrequency inputs without digitization at high speed and with low energy costs—an important step for artificial intelligence at the edge.

The alternative splicing regulator MBNL1 is overexpressed in MLL-rearranged leukaemia. Here, the authors show that MBNL1-mediated alternative splicing leads to a specific splicing profile in MLL-rearranged leukaemia and loss or inhibition of MBNL1 impairs leukaemia development in vitro and in vivo.

A single-cell multiomics analysis of over 200,000 cells of the primary motor cortex of human, macaque, marmoset and mouse shows that divergence of transcription factor expression corresponds to species-specific epigenome landscapes, and conserved and divergent gene regulatory features are reflected in the evolution of the three-dimensional genome.

The RNA endonuclease CPSF3 was identified as the cellular efficacy target of the small molecule JTE-607, revealing pre-mRNA processing as a vulnerability in cancers such as Ewing’s sarcoma that are characterized by aberrant transcription.

Apicomplexan parasites share complex cell pellicular structures that isolates the cytosol from most of the plasma membrane. Koreny et al show that, as an early adaptation to this barrier, dedicated stable endocytic structures occur at select sites in these cells. In Toxoplasma, plasma membrane homeostasis is particularly dependent on endocytosis.
