In this study, the authors present optimization and efficacy testing of apolipoprotein-based lipid nanoparticles for delivering various nucleic acid therapeutics in vivo to immune cells and their progenitors in the bone marrow.

Plasmacytoid dendritic cells produce type I interferons in response to viral sensing. Here the authors show that amines inhibit these plasmacytoid dendritic cell responses through CXCR4 engagement.

Neoadjuvant immunochemotherapy against NSCLC has been tested in clinical trials. Here, the authors follow up longer-term survival and measure immune cell phenotype changes in a single-arm phase II clinical trial of neoadjuvant immunochemotherapy, indicating association of intratumoural TCR diversity and CD8 T cell positioning.

This prespecified updated survival and exploratory subgroup efficacy analysis of the phase 3 DESTINY-Breast04 trial shows that trastuzumab deruxtecan treatment in patients with HER2-low metastatic breast cancer leads to continuous survival benefit irrespective of estrogen receptor or hormone receptor status.

The authors use atomistic calculations with machine-learned interatomic potentials to show that dislocation motion in metals like iron and tungsten involves a nearly constant activation entropy, challenging prior models and improving strength predictions.

Genome-wide association meta-analyses of attention-deficit/hyperactivity disorder symptom measures and clinical diagnoses identify new risk loci, highlight putative effector genes and yield improved polygenic risk scores.

Although uranium-nitrogen multiple bonding is well developed, there are far fewer uranium-phosphorus and -arsenic multiple bonds, and none for antimony, even in spectroscopic scenarios. Here, the authors report syntheses of uranium-stibido, -stibinidiide, -distibene, and -stibinidene derivatives containing single, double, and pseudo-triple bond interactions.

Here the authors apply ZooMS, radiocarbon, and stable isotope analyses to whale bones from the Bay of Biscay. They find that humans were utilizing the remains of at least five species of whales from 20,000 years ago, and that those whale communities may have resembled today’s arctic waters.

Serino et al. show that seeing an infectious avatar approach the body in virtual reality triggers an immune response, indicating that the brain prepares the body to fight infections even for perceived, but not real, threats.

Species synchrony is considered a major mechanism of biodiversity–ecosystem stability relationships. Here, by combining theory, modelling and empirical work, the authors show that with time series length species synchrony decreases and its relationship with diversity switches from positive to negative.

Single-agent maintenance PARP inhibition may represent an effective strategy for advanced/metastatic endometrial cancer treatment. Here this randomized phase IIb UTOLA trial evaluates the efficacy and safety of orally administered olaparib in female patients (n = 145) without progression following front-line platinum-based chemotherapy for advanced/metastatic endometrial cancer.

Population genomics and meta-transcriptomics reveal a role of nitric oxide production and accessory genes in the virulence of the banana wilt-causing fungal pathogen Fusarium oxysporum.

2023 CX1 is the only L-chondrite-like asteroid analysed from space to ground. It catastrophically fragmented in the atmosphere, depositing 98% of its energy in one burst—an unusual, high-risk fragmentation mode with implications for planetary defence.

Lipid particles loaded with RNA coding for tumour-unspecific antigens can enhance early responses of type-I interferons, mediating the success of immune checkpoint inhibitors as well as epitope spreading.

Klebanoff and colleagues report that survival and persistence of CAR-T and CAR-NK cells are regulated by a FAS ligand–FAS autoregulatory circuit, showing that disabling FAS signaling enhances their antitumor efficacy in preclinical models.

Magneto-chiral dichroism is an effect in which unpolarized light is absorbed differently for parallel and antiparallel propagation with respect to an applied magnetic field. Previous observations have only seen a rather weak demonstration of this effect. Following a challenging synthesis, strong magneto-dichroism has now been observed in enantiopure chiral ferromagnets.

Genome-wide sequencing of 180 ancient individuals shows a continuous gradient of ancestry in Early-to-Mid-Holocene hunter-gatherers from the Baltic to the Transbaikal region and distinct contemporaneous groups in Northeast Siberia, and provides insights into the origins of modern Uralic and Yeniseian speakers.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

Plasmonic chiroptical materials suffer from the challenge of combining intense signals with dynamic tunability. Here, the authors present chiroptically active materials composed of linearly assembled gold nanoparticles with birefringent polymer films that enable dynamic tuning of CD signals by mechanical stretching.

Genomic analysis of Plasmodium DNA from 36 ancient individuals provides insight into the global distribution and spread of malaria-causing species during around 5,500 years of human history.

Federated learning (FL) algorithms have emerged as a promising solution to train models for healthcare imaging across institutions while preserving privacy. Here, the authors describe the Federated Tumor Segmentation (FeTS) challenge for the decentralised benchmarking of FL algorithms and evaluation of Healthcare AI algorithm generalizability in real-world cancer imaging datasets.

Ossenkoppele, Coomans and colleagues analyzed the tau PET data of 12,048 individuals from 42 cohorts worldwide. They found that age, amyloid-β status, presence of an APOE ε4 allele and female sex are key contributors to tau PET positivity, which should aid clinical decision-making and trial designs.

Mazan-Mamczarz, Tsitsipatis and colleagues apply single-cell and spatial transcriptomics to mouse models of atherosclerosis to map senescent cells contributing to plaque instability and arterial remodeling. They define a transcriptomic signature of vascular senescence.

Together with an accompanying paper presenting a transcriptomic atlas of the mouse lemur, interrogation of the atlas provides a rich body of data to support the use of the organism as a model for primate biology and health.

Together with a companion paper, the generation of a transcriptomic atlas for the mouse lemur and analyses of example cell types establish this animal as a molecularly tractable primate model organism.

Hybridizations between different wild species and subspecies within Musa genus lead to the origin of current banana cultivars with different ploidy level and constitution. Here, the authors assemble seven genomes from different ancestral genetic groups and show the speciation process is accompanied by chromosome rearrangements.

Analysis of soundscape data from 139 globally distributed sites reveals that sounds of biological origin exhibit predictable rhythms depending on location and season, whereas sounds of anthropogenic origin are less predictable. Comparisons between paired urban–rural sites show that urban green spaces are noisier and dominated by sounds of technological origin.

The scope of Lewis acid catalysis mediated by enzymes is low compared with the range of reactions it drives in organic synthesis. Now the substitution of the iron centre with copper, and the subsequent directed evolution, enabled a non-haem iron hydroxylase to efficiently catalyse asymmetric abiotic Conia-ene cyclizations.
