Analyses of snRNA genes in a French cohort of people with rare disorders, with validation through international collaboration, identify monoallelic and biallelic variants in RNU2-2 as frequent causes of neurodevelopmental disorders with epilepsy.

It remains unclear why some BRCA-deficient high-grade serous carcinomas (HGSC) do not respond to platinum-based therapy. Here, multi-omic analysis of BRCA1- and BRCA2-deficient HGSC attributes co-occurring mutations, DNA repair deficiency and tumor microenvironment features to short survival in these patients.

A study of reproducibility in a stratified random sample of 600 papers published from 2009 to 2018 in 62 journals spanning the social and behavioural sciences finds higher reproducibility among more recent papers and papers from journals that require data sharing.

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer’s disease, but it is not deterministic. Here, the authors show that common genetic variation changes how APOE-ε4 influences cognition.

Tracking oceanic microbial populations in situ over time is challenging. Here, the authors use autonomous underwater vehicles to show how microbes at the deep chlorophyll maximum respond to diel cycles and isopycnal uplift by a cyclonic eddy.

Karapetyan et al. report how multiscale electron ptychography, a computational electron microscopy technique with sub-Ångström lateral and nanometer-scale depth resolution, enables 3D imaging of buried features (distortions, defects, and roughness) in gate-all-around transistors, guiding the semiconductor fabrication.

Using cryo-EM, Cui et al. map distinct conformational states of the HIV-1 envelope glycoprotein (Env). The study establishes a classification framework for these dynamic structures and a mechanism of Env conformational changes from closed to fully open.

Genome-wide analysis coupled with long-read sequencing identifies a repeat expansion in GOLGA8A associated with high risk for atypical frontotemporal lobar degeneration with ubiquitin-positive inclusions.

Single-nucleus chromatin and RNA sequencing identifies epigenetic chromatin domains that confer vulnerability to paediatric brain tumours such as ependymomas, providing insight into the development of such tumours despite ‘quiet’ genomes.

Cancer associated fibroblast subpopulations are identified by single cell and spatial sequencing as relevant components of the brain metastasis tumor microenvironment, where they participate in the tissue architecture and intercellular communication.

Trained and validated on data from 2,344 patients with smoldering multiple myeloma, a new algorithm using longitudinal biomarker dynamics provides accurate prediction of risk of disease progression, outperforming established models.

Here, the authors present aDNA from 49 grape pips spanning the Bronze Age to Medieval period in France and surrounding areas. They find evidence of long-distance exchange of domestic varieties through vegetative clones and one Medieval sample that is nearly identical to modern Pinot Noir.

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.

LIGO–Virgo–KAGRA’s fourth Gravitational-Wave Transient Catalog shows evidence of a clear pair-instability gap in the distribution of binary black-hole secondary masses but is absent in the larger primary masses.

From 2014–2017, marine heatwaves caused global mass coral bleaching, where the corals lose their symbiotic algae. The authors find, this event exceeded the severity of all prior global bleaching events in recorded history, with approximately half the world’s reefs bleaching and 15% experiencing substantial mortality.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

Photocatalysts for methane conversion can suffer from inefficient charge carrier diffusion, limiting their effectiveness. Here the authors exploit the insulator–metal transition in VO₂ to create an electronic phase junction, enhancing the non-oxidative conversion of methane into hydrogen, ethane and propane, with peak efficiency at the transition’s critical temperature.

Hyperpolarized ¹³C-enriched pyruvate has demonstrated promise for imaging metabolism in cancer, heart disease and neurodegenerative disorders; however, broader clinical adoption is constrained by the cost and limited availability of current hyperpolarization technology. Here, the authors report in situ hyperpolarization of pyruvate at 6.5mT by SLIC SABRE, demonstrating its application in low-cost high-performance ¹³C MRI at milli Tesla fields with sufficient resolution to distinguish chemical shifts between pyruvate isotopomers.

Disulfide tethering screening is applied to address the challenge of targeting oncogenic KRAS, historically deemed undruggable due to its high nucleotide affinity and perceived lack of binding sites. Here, the authors developed a disulfide library and a set of 83 cysteine KRAS mutants to perform tethering screens towards the oncogenic KRAS, while describing the discovery of fragment-binding pockets in KRAS G12D, identified by this screening approach.

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.

It is unclear whether the harsh abiotic conditions of drylands hinder biological invasions. This global analysis shows that drylands are vulnerable to non-native plants and are likely to become more so as native plant diversity declines and grazing pressure intensifies.

The identification of cellular targets for natural products that potently inhibit the growth of cancer cell lines implicates oxysterol-binding proteins in the growth of cancer cells. These natural products, termed ORPphilins, also affect sphingomyelin biosynthesis.
