An ex vivo model and pre-clinical study in a brain-dead recipient provide enzyme-converted O organs to avoid hyperacute rejection in ABO-incompatible kidney transplant patients.

Phosphorus is an essential plant nutrient. Here Meng et al. show that low phosphorus availability stimulates hydrogen peroxide production which in turn promotes the oligomerization, nuclear translocation and DNA binding activity of the PHR2 transcription factor and enhances the phosphate starvation response.

Cryo-electron microscopy was used to study human mechanistic target of rapamycin complex 1 (mTORC1) activation on lysosomal membranes, showing progressive recruitment by RAG–Ragulator, RHEB and RAPTOR, culminating in mTOR–membrane engagement and full enzyme activation.

A chromatin-associated complex, which is dynamically regulated by TOR kinase at the translational level, functions to suppress the transcription of stress-responsive genes marked by histone acetylation, thereby coordinating plant growth and stress tolerance.

A study of several longitudinal birth cohorts and cross-sectional cohorts finds only moderate overlap in genetic variants between autism that is diagnosed earlier and that diagnosed later, so they may represent aetiologically different conditions.

Previous studies have suggested that branched chain amino acids (BCAA) may contribute to the development of diabetic kidney disease (DKD).Here the authors report that genetic disruption of BCAA catabolism in podocytes or exogenous BCAA supplementation can trigger DKD initiation via rewiring of glucose metabolism in mice.

Rice-infecting arboviruses adopt convergent strategies to overcome host defenses. Here, the authors show that viral proteins from distinct rice viruses boost OsTSN1 nuclease activity to suppress rice antiviral RNA decay immune response through promoting its phase separation and multimerization.

Yin, Lin, Cai, Nie and colleagues report phase separation of ERCC6L2 as a mechanism that regulates RNF138-mediated ubiquitination and degradation of CtIP, thereby modulating DNA end resection and treatment response to ATM inhibitors in cancer.

Through binding mitochondrial ATP synthase, engineered nanomedicines rejuvenate aged bone stem cells and restore osteogenesis, reversing osteoporosis in mice and offering a potential senolytic therapy for skeletal ageing.

Inhibition of ELOVL6, a fatty acid elongation enzyme, selectively degrades mutant KRAS, disrupts its membrane localization and suppresses tumor growth, revealing a novel vulnerability in KRAS-driven cancers.

The insecticidal protein Mpf2Ba1 shows potent control against corn rootworm. Here, the authors present detailed structural analyses revealing transitions between its three main stages of pore formation. These findings uncover molecular mechanisms of bacterial pore assembly and advance both crop biotechnology and food security.

More students than ever are studying across international borders, but where and what they learn is shifting.

The mechanisms linking neuropsychiatric and metabolic disorders remain unclear. The authors show a pancreas–hippocampus feedback loop whereby metabolic and circadian factors drive behavioral fluctuations, with potential relevance for bipolar disorder.

Intracellular α-ketoglutarate availability dictates energy sensing through regulation of TET–YBX1-dependent AMP-activated protein kinase synthesis, which prevents disulfide stress accumulation and cell death in cancer cells.

Polygenic scores for body mass index and obesity constructed using data from 5 million people with different ancestries were associated with distinct weight gain trajectories from early childhood to adulthood.

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.

Gut microbiota-derived succinate promotes CitC succinyltransferase-dependent succinylation of PurR to alleviate T3SS repression and promote virulence in enterohaemorrhagic Escherichia coli and Citrobacter rodentium.

Atmospheric rivers are responsible for much of the poleward water vapour transport in the mid-latitudes and can cause extreme precipitation after landfall. Here, the authors show that ocean fronts and eddies can influence atmospheric rivers and increase the associated precipitation along the North American west coast.

The Consortium on Asthma among African-ancestry Populations in the Americas (CAAPA) aims to better understand population genetics of the African diaspora. Here, it uses deeply sequenced whole-genomes to describe the impact of admixture and potential disease burden of deleterious variants.

The role of Leflunomide in αPD1-induced cardiotoxicity remains unclear. Here, the authors show that leflunomide mitigates αPD1-induced cardiac toxicity in melanoma-bearing mice through modulation of the microbiota-indole-3-propionic acid-heart axis.

R9AP is a key receptor for entry of Epstein–Barr virus into human epithelial and B cells, and interacts directly with the viral glycoprotein gH/gL complex to mediate virus–host membrane fusion.

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.

It is challenging to purify and prepare large amount of methacrylated proteins from cells. Here, the authors develop genetic code expansion technology to site-specifically incorporate ε-N-Methacryllysine into proteins and identify the post-translational modification ε-N-methyl-ε-N-methacrylation.

Fan et al. report a role for PRMT5 in regulating GPX4 stability and ferroptosis sensitivity through arginine methylation, which may be targeted to inhibit tumour development.

A PICALM allele associated with increased risk of late-onset Alzheimer’s disease has a microglial-specific role in lipid droplet accumulation.

The high-throughput identification of cross-linking peptides is challenging. Here, the authors developed an enrichable and cleavable latent bioreactive unnatural amino acid eFSY, and a software AixUaa to improve the cross-linking peptides indentification in live cells.

Zhang et al. show that YAP binds to TDP-43 to promote TDP-43 multimerization and phase separation. YAP and TDP-43 may co-localize in multiple cell types in oxidative stress and in brain samples from individuals with amyotrophic lateral sclerosis.

Fan et al. show that cTAGE5 is essential for adipogenesis and adipose tissue development. Mechanistically, cTAGE5 promotes pro-insulin receptor processing, which mediates actin cytoskeleton remodeling and lipolysis during the adipocyte differentiation.

Tumour cells can alter the function and metabolism of immune cells to reduce anti-tumour responses. Here the authors use single cell sequencing of HCC and show three tumour archetypes; metabolism, inflammation and stemness and the metabolism archetype are found in association with TREM⁺ macrophages which restrict immune cell infiltration into the tumour microenvironment.

The mechanism of HIV-1 latency reversal remains unclear. The authors suggest that PRMT3 drives the reversal by enhancing chromatin accessibility to form a transcriptional hub containing TEAD4 and P-TEFb at the viral promoter.

The role of glioma cellular metabolism in response to oncolytic herpes virus (oHSV) therapy remains to be studied. Here the authors report that oHSV induces metabolic reprogramming in IDH wildtype glioma cells, leading to ferroptosis and anti-tumor immune response. Pharmacological blockade of mutant IDH enhances glioma cell sensitivity to oHSV therapy.

International trade links regions of production and consumption. Analyses with a multiregional input–output model based on trade data reveal that much of East Asia’s aerosol radiative forcing is tied to consumption in developed countries.
