Fatty liver disease exacerbates atherosclerosis, but the underlying mechanisms remain unclear. Here, the authors show that D-dopachrome tautomerase (D-DT/MIF-2) acts as an atypical chemokine, promoting both atherosclerosis and hepatic lipid accumulation.

Immunotherapies now dominate the treatment landscape for melanoma, but why they only work in a subset of patients remains unclear. Here, the authors perform an immunogenomic analysis on 67 intratumor sub-regions of a PD-1 inhibitor resistant melanoma, and 2 additional metastases from a single patient, mapping the spatial relationships between genomic and immune heterogeneity at high resolution.

Toxicities limit combination of PARP inhibitors (PARPi) and chemotherapy in patients with germline BRCA1 and BRCA2 pathogenic variant (gBRCAm) breast cancer. Here, the authors report a preclinical study followed by a randomised phase II/III clinical trial investigating the addition of a gap between chemotherapy (carboplatin and paclitaxel) and PARPi (olaparib), in patients with early gBRCAm breast cancer.

Simultaneous profiling of RNA and chromatin accessibility in single nuclei isolated from human postnatal brain regions from infancy to late adulthood identifies key cellular regulators and nominates target genes and mechanisms for brain-related diseases and disorders.

Human decision-making, including cooperation, is shaped by motivations. Here, the authors develop a modelling framework to show that motivations for cooperation evolve when the benefit-to-cost ratio exceeds a threshold and social network structure can alter the evolutionary outcome.

The Star of David topology is an iconic symbol that has been used in religious and cultural contexts for thousands of years. Now it is assembled in molecular form through a hexameric circular helicate generated by six tris(bipyridine) ligands entwined about six iron(II) cations. The structure of the two triply-entwined 114-membered rings is revealed by X-ray crystallography.

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.

Two orthogonal mass spectrometry techniques reveal that both the Fc and Fab domains of IgGs make direct interactions with FcRn, which could inform the engineering of new improved therapeutic IgGs.

The long-term effect of prenatal nutrition on gene regulation is largely unknown. Here the authors identify differentially methylated regions in whole blood from individuals exposed to famine early after conception, and show that these epigenetic changes may have adverse metabolic consequences later in life.

The degree to which the diurnal light/dark cycle influences Mg-heterogeneity in foraminifera with complex shell morphologies remains unknown. Here, using highly spatially resolved analytical techniques, the authors investigate Mg-banding and calcification in isotope-labelledNeogloboquadrina dutertreispecimens.

Excitatory neurons in the neocortex exhibit considerable morphological diversity, yet their organizational principles remain a subject of ongoing research. Here, the authors use unsupervised learning to show that most excitatory neuron morphologies in the mouse visual cortex form a continuum, with notable exceptions in deeper layers.

Analysis of the blood DNA virome in patients with COVID-19 and autoimmune disease associates endogenous HHV-6 (eHHV-6) and high anellovirus load with increased disease risk, most notably for systemic lupus erythematosus. eHHV-6 carriers show a distinct immune response.

Familial adenomatous polyposis (FAP) is an inherited gastrointestinal syndrome associated with duodenal adenoma formation. Here the authors show that IL17A-producing NKp44- group 3 innate lymphoid cells accumulate in FAP duodenal tissue and are associated with duodenal adenoma formation in patients with FAP.

Genomic and functional analyses of healthcare-associated vancomycin-resistant Enterococcus faecium reveal that bacteriocin T8 is enriched in emergent lineages and provides a competitive advantage in vitro and in vivo.

The accuracy of melanoma diagnosis can vary considerably among clinicians, impacting both patient outcomes and the performance of related AI tools. Here, the authors systematically assess interrater variability among expert pathologists reviewing histopathological images and clinical metadata of melanoma-suspicious lesions collected at eight German hospitals.

FIORA, an advanced graph neural network, enhances the simulation of tandem mass spectra by learning molecular bond-breaking patterns. The open-source algorithm generates high-quality reference spectra for compound identification in metabolomics.

CHIMERYS is a spectrum-centric and data acquisition method-agnostic algorithm for the analysis of MS2 spectra. It is capable of deconvoluting any MS2 spectrum, regardless of whether it was acquired by DDA, DIA or PRM, thus unifying the analysis of bottom-up proteomics data.

An RNA-binding protein on leukemia cells provides an effective target in mouse models.

Cell2fate improves RNA velocity analysis of single-cell and spatial transcriptomics data by module decomposition of realistic biophysical models of transcription dynamics.

Recently, negative pressure has been observed in perovskite nanowires by annealing the wires from a lower-density phase. Here, the authors show that the negative pressure enhances the piezoelectric coefficient of PbTiO₃ and Pb(Zr,Ti)O₃ nanowires experimentally and by ab initiocalculations.

Mechanisms underlying treatment failure of antileishmanial therapy are unclear. Here the authors provide transcriptome data of innate immune cells from cutaneous leishmaniasis patients undergoing treatment and find that a heightened type-I interferon response is associated with treatment failure.

Synthesizing the cellular proteome is demanding and finely regulated. Here, the authors show that mTORC1 cooperates with tRNA wobble modification to promote ribosomal protein synthesis, thus supporting the high translational demands of cell growth.

Livanos et al. provide mechanistic insight into the recruitment and maintenance of kinesin-12 POK2, a central component of the division site in plants that is required for cell plate positioning during cytokinesis.

Madrer et al. identify a Parkinson’s disease–specific increase in transfer RNA (tRNA) fragments in human blood, cerebrospinal fluid and postmortem brain tissue, demonstrating the ability of blood-based tRNA fragment quantification to distinguish between pre-symptomatic patients and healthy controls.

Iron is crucial for cellular metabolism, but its availability varies greatly within and between individuals and populations. This Review highlights how iron regulates innate and adaptive cellular and humoral responses affecting protection against infections, tumours and autoimmunity.

Most genomics research cohorts are made up of participants of European ancestry, which limits the reach of precision medicine. Here, the authors describe the genetic diversity in the All of Us research program, which is enriched in underrepresented ancestries.

A large-scale analysis of DNA-bound transcription factors (TFs) shows how the presence of DNA markedly affects the landscape of TF interactions, and identifies composite motifs that are recognized by complexes of TFs rather than by individual ones.
