Radiation-induced mucositis significantly reduces patient quality of life. Here, the authors report on inorganic-free nanosheets that selectively capture inflammatory small extracellular vesicles, reducing oxidative stress, restoring immune balance and reducing radiation-induced mucositis.

Electrostatic effects of separators under internal electric field is crucial for Li metal batteries. Here, authors develop a high dielectric constant fiber separator that shows substantial polarization under electric field to facilitate a robust and low-resistance solid-electrolyte interphase.

Radiopharmaceuticals engineered with click chemistry to selectively bind to tumour-specific proteins can be used to successfully target tumour cells, boosting the pharmacokinetics of radionuclide therapy and improving tumour regression.

Rooftop photovoltaic systems are often seen as a niche solution for mitigation but could offer large-scale opportunities. Using multi-source geospatial data and artificial intelligence techniques, the authors map their potential for reducing global temperatures and analyse regional differences.

Personalized antibacterial agents against diverse bacteria strains are promising for combating antimicrobial resistance, but a balance between strain specificity and broad-spectrum bactericidal activity is elusive. Here, the authors report an antibacterial nanoagent TiOx@C with bacterial cell wall specificity, multi-targeting and bactericidal effect against S. aureus and P. aeruginosa.

The authors demonstrate that salt stress activates CDK8, which phosphorylates AHL10 and promotes its degradation. AHL10 is involved in recruiting SUVH2/9 to repress salt-responsive genes. The CDK8-AHL10-SUVH2/9 module is critical for transcriptional dynamics in response to salt stress.

The molecular mechanisms underlying the function of different cellular states in glioblastoma stem cells (GSCs) remain poorly understood. Here, the authors perform integrated single cell and bulk analysis of GSCs and identify potential therapeutic targets.

Off-target effects have limited RNA degradation approaches. Here, the authors develop a tumor microenvironment-activated ribonuclease targeting chimera (RiboTAC) demonstrating H₂O₂ and acid activated degradation of pre-miR-21, which was effective in restoring radiosensitivity in lung cancer.

While cotton fiber development has been extensively studied, the spatiotemporal transcriptome and metabolome landscape remain largely unknown. Here, the authors profile early stage cotton fiber cell using a combination of spatial transcriptomic, single-cell transcriptomic, and spatial metabolomic analyses.

The inclusion of base Z has the potential to heighten the binding affinity between complementary nucleic acids. Here, the authors integrated base Z into CRISRP-Cas12a crRNA to augment the interaction between the crRNA and the target DNA, resulting in a significant enhancement of editing efficiency.

Difficulties in propagating HRV-C have hindered our understanding of this common respiratory pathogen. Here, authors developed an organoid-based system to reproducibly propagate HRV-C and characterized HRV-C infection in physiologically active respiratory organoids.

SERS spectroscopy critically relies on the accumulation of analyte molecules in electromagnetic ‘hotspots’. Here, the authors demonstrate plasmonic trimers with central particles that act as chemical traps, enabling the subtyping of lung tumors using fresh tissue samples.

Liang, Yan, Long, Ji et al. find that the origin and dynamics of 5-hydroxymethylcytosine (5hmC) during early development are not conserved between humans and mice and that 5hmC contributes to the activation of human embryonic genes.

Improved cytosine base editors are created by repurposing an adenine deaminase.

Here, the authors generate near-field circularly polarized dipole modes in a hBN/WSe₂/hBN–Au nanoantenna hybrid structure by electron beam excitation, and show nanoscale control of the valley polarization through spatial variation of the electron beam excitation position.

Artificial intelligence is rapidly being integrated into Earth science, but how Earth science may benefit artificial intelligence has been overlooked. We call for mutual balancing between the two disciplines and improving cross-disciplinary collaboration.

Kagome materials host 2D planes which give rise to kagome physics, but these are typically embedded in the bulk. Huang et al. demonstrate a strategy for generating surface kagome electronic states by vertical p-d electronic hybridization between surface atoms and the buried Co kagome network in Co₃Sn₂S₂.

High homocysteine plasma levels are associated with cardiovascular diseases. Here, Li and colleagues find that homocysteine aggravates vascular injury by direct binding to the angiotensin II type 1 receptor (AT1R), identifying AT1R inhibition as a potential strategy to counteract the deleterious vascular effects of hyperhomocysteinemia.

Potential rooftop photovoltaic in China affords 4 billion tons of carbon mitigation in 2020 under ideal assumptions, equal to 70% of China’s carbon emissions from electricity and heat. Yet most cities have exploited the potential to a limited degree.

Iron deficiencies are a common non intestinal symptom seen in patients with irritable bowel disease. Here the authors show an associative link between microbiota assisted uptake of nutrients including iron and the promotion of immune tolerance in the intestine.

Catalysts with multiple and modulable reaction pathways are promising but generally hampered by inconsistent reaction conditions and negative internal interferences. Herein, the authors report an adaptable graphitic C6N6-based copper singleatom catalyst

The immune receptor Transmembrane and immunoglobulin ___domain containing 2 (TMIGD2) mediates T-cell and nature killer cells co-stimulation upon B7-family HHLA2 engagement. Here, the authors show that TMIGD2 is expressed in Acute Myeloid Leukaemia stem cells regulating self-renewal and differentiation to facilitate leukemogenesis.

Metal-carbon σ bonds mark the basis of organometallic chemistry, but the formation of multiple such bonds between single organic and metal entities remains a challenge. Here, the authors report a one-pot aromaticity-driven method to construct osmium-based multidentate complexes containing three metal-carbon σ bonds from multiyn chains.

Coordination complexes based on polydentate ligands that contain both nitrogen and carbon ligating atoms are ubiquitous, but design of those with planar cores remains challenging. Here the authors show that complexes with planar CCCN, CCCCN and NCCCN cores can be accessed by modification of the coordinating atoms in CCCC core complexes.

Methods to integrate Earth system modelling (ESM) with deep learning offer promise for advancing understanding of Earth processes. This Perspective explores the development and applications of hybrid Earth system modelling, a framework that integrates neural networks into ESM throughout the modelling lifecycle.

EF-G catalyzes translocation of tRNA–mRNA in the ribosome. Biochemical and structural analyses of EF-G indicate that EF-G disrupts interactions between the decoding center and the codon–anticodon duplex that constitute the barrier for translocation.
