Global Burden of Disease analysis found that in 2023, suboptimal diet was estimated to be responsible for 4 million deaths and 97 million morbidity burdens from ischemic heart disease.

A high-resolution spectroscopic analysis reveals ultralow amounts of heavy elements in the star SDSS J0715−7334. The star originates from the Large Magellanic Cloud and probably formed directly after the first stars through dust cooling.

A study investigating the emergence of squamous tumours in the upper gastrointestinal tract of the mouse shows that an initial tumour stress response triggers fibroblasts to remodel the underlying stroma, creating a fibronectin-rich precancerous niche that supports tumour survival.

Single-variant and ultrarare variant burden analyses leveraging exome sequencing data from 22 cohorts identify new risk genes for amyotrophic lateral sclerosis and show cumulative effects of several rare variants on disease risk.

An analysis of rare disease cohorts from the UK, the USA, Italy and the Netherlands identifies a neurodevelopmental disorder caused by biallelic variants in RNU2-2. Individuals with this disorder have substantially reduced levels of U2-2 small nuclear RNA in blood.

Over five years, implementation of the NHS England Lung Cancer Screening Programme achieved high early-stage detection rates and demonstrated that the programme is both feasible and scalable for reaching high-risk and underserved populations.

In triple-negative breast cancer, the kinase PIM1, which is highly expressed, functions through the transcription factor c-MYC to promote tumor cell survival and growth.

Global Burden of Disease estimates show that between 1990 and 2023, the prevalence and burden of drug use disorders, inclusive of amphetamine, cannabis, cocaine and opioid use, have been increasing in high-income countries, particularly in the USA.

A star in a primordial dwarf galaxy has preserved the elements produced by the first generation of stars. The star lacks heavy elements but exhibits an extreme amount of carbon, suggesting that low-energy explosions can seed the initial chemistry of early galaxies.

The population genome structure of Asian Toxoplasma remains incompletely understood. This study analyzes intercontinental genomic admixture in 17 isolates from Japan and China, providing insights into the evolution of parasites and their impact on public health.

Although antiretroviral therapies (ART) have expanded the life expectancy of patients with HIV, they are not curative due to the presence of latently infected cells. Here, the authors present IMC-M113V, a bispecific soluble TCR targeting the HIV peptide Gag_77-85 complexed to HLA-A*02:01 as an approach for targeting HIV reservoirs and test safety, tolerability and pharmacodynamics in a first-in-human clinical trial on 12 HLA-A*02:01-positive male individuals on ART.

Eggplants are important vegetables worldwide. Here, the authors report 40 genome assemblies of Solanum melongena, its progenitor S. insanum and the allied species S. incanum to construct two pangenomes, and identify loci associated with multiple traits via pangenome-wide association analysis.

National climate institutions could greatly impact the process of policy design and implementation. This analysis identifies four models of climate governance for major emitters, estimates their policy ambitions and performance, then shows how they are related to macro features.

IgE antibodies targeting cancer antigens can be used for immunotherapy. Here the authors present an IgE antibody targeting the melanoma-associated antigen, chondroitin sulphate proteoglycan 4, that recognises human melanoma, stimulates tumour cell cytotoxicity, and restricts tumour growth in humanised mouse models.

An IgE antibody recognising Folate Receptor-alpha has been tested in clinical trials for ovarian cancer and preclinical studies show macrophage involvement in the anti-tumoural functions of IgE. Here the authors demonstrate that IgE induces proinflammatory activation of ovarian cancer patient macrophages, which reverses their immunosuppressive induction of Treg cells and promotes CD8⁺ T cell function.

Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

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.

Glaciers lost 408 ± 132 Gt of mass during the hydrological year 2025, equivalent to 1.1 ± 0.4 mm sea-level rise. Since 1975, glacier mass loss has totalled 9,583 ± 1,211 Gt, equivalent to 26.4 ± 3.3 mm of sea-level rise, with six of the highest mass-loss years on record occurring in the past seven years.

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.

The authors demonstrate that KAI2-dependent signaling, which perceives an unknown ligand referred to as KL, promotes vegetative reproduction in Marchantia polymorpha by regulating cytokinin levels through the control of MpLOG expression.

Melting from the Greenland Ice Sheet triggers land uplift beneath the ice sheet and changes to Earth’s gravitational field and rotation axis, a process called Glacial Isostatic Adjustment. Lewright et al. find that this process will lead to a local sea level fall along Greenland’s coast over this century.

Migrating cancer cells are round or elongated, and it is thought that the differently shaped cells invade surrounding tissue using different mechanisms. Here, Orgaz et al. show that the round cells secrete matrix metalloproteinases, which allow them to degrade surrounding connective tissue more effectively than elongated cells.

A common immune signature in the blood of patients with COVID-19, who are otherwise clinically heterogeneous, sheds light into the pathogenesis and clinical progression of the disease.

A comprehensive multi-omics reference atlas of prenatal human skin shows that innate immune cells crosstalk with non-immune cells to perform pivotal roles in skin morphogenesis, including the formation of hair follicles.

GluFormer, a generative foundation model, uses continuous glucose monitoring data to accurately forecast glycaemia-related health responses, particularly for long-term outcomes.

Across three experiments, Baror et al. show that context shifts reduce serial dependence (bias towards prior choices) and shape memory at event boundaries.

Here the authors provide an explanation for 95% of examined predicted loss of function variants found in disease-associated haploinsufficient genes in the Genome Aggregation Database (gnomAD), underscoring the power of the presented analysis to minimize false assignments of disease risk.

Integrated multi-omic analyses using samples from the TRACERx study highlight cross-talk between DNA hypermethylation and genomic lesions in non-small cell lung cancer.

Releasing only males remains a major hurdle for mosquito genetic control. Here, authors develop a mosquito strain using CRISPR and a synthetic sex chromosome, producing dark males and yellow females that develop slower and lay desiccation-sensitive eggs, enabling easy separation and safe releases.

High-depth sequencing of non-cancerous tissue from patients with metastatic cancer reveals single-base mutational signatures of alcohol, smoking and cancer treatments, and reveals how exogenous factors, including cancer therapies, affect somatic cell evolution.

Keratin 76 (Krt76) is an epithelial differentiation marker that is downregulated in oral squamous cell carcinomas, correlating with poor prognosis. Here the authors show that genetic ablation of Krt76 in a mouse model results in increased susceptibility to carcinogenesis via enhanced accumulation of Tregs.
