PINK1/Parkin-mediated ubiquitin-dependent mitophagy is a key regulator of browning in inguinal white adipose tissue (iWAT). Here, the authors report that PNPLA7, an Endoplasmic Reticulum and mitochondria-associated membrane (MAM) protein, inhibits browning of iWAT by promoting PINK1/Parkin-mediated mitophagy upon cold challenge or adrenergic receptor agonist treatment.

Renal cell carcinoma consists of several subtypes, and recurrence is highly dependent on subtype. Here, the authors develop a multi-classifier using imaging, lncRNA and clinical data to predict recurrence in papillary renal cell carcinoma.

The concept of topological corner states in two dimensional topological insulators can be generalised to higher dimensions. Here, authors present a three dimensional acoustic metamaterial that exhibits the full hierarchy of topological multipole states including corner, hinge, surface and bulk states.

Low-frequency quasiperiodic oscillations in X-ray data are thought to trace the accretion flow in X-ray binaries. Here, the detection of 200 keV oscillations probes the innermost regions of MAXI J1820+070, revealing the precession of a small-scale jet.

The death of massive stars has traditionally been discovered by explosive events in the gamma-ray band. Liu et al. show that the sensitive wide-field monitor on board Einstein Probe can reveal a weak soft-X-ray signal much earlier than gamma rays.

Current-driven dynamic atomic rearrangements in layered In₂Se₃ are visualized. The authors identify an intralayer ‘unzipping’ and interlayer ‘zipping’ phase-transition pathway in which bond formation across the van der Waals gaps drives bond cleavage within covalent layers.

Guan et al. analyse the impacts of COVID-19 restrictions on global supply chains. Earlier, stricter and shorter lockdowns can minimize overall losses. A ‘go-slow’ approach to lifting restrictions may reduce overall damages if it avoids the need for further lockdowns.

Socioeconomic status is multidimensional and can change over time. Xu, Lui, Ji et al. found dimension-specific, late-stage-specific and change-specific socioeconomic effects on brain, cognition, personality and emotion.

In this work, authors show that the key epigenetic regulator Gcn5 contributes to multidrug resistance in Candida auris. The inhibition of its activity by CPTH₂ synergizes with caspofungin, presenting a promising antifungal strategy.

Non-invasive approaches for risk stratification and screening remain crucial for colorectal cancer (CRC). Here, the authors develop a model for CRC risk stratification by integrating plasma proteomics data with polygenic risk score and QCancer-15 risk score, which could guide recommendations for earlier screening of high-risk populations.

Conventional methods for nanoparticle cluster formation involve surface functionalization, which can alter the properties. Here, the authors propose a non-disruptive strategy to position nanomaterials of different shapes between nanosheets without the need for pre-modification.

Cross-ancestry genome-wide association studies of 3,414 brain imaging phenotypes in Chinese Han and white British participants identify autosomal and X-chromosomal associations in more diverse populations.

Artificial magnetic fields have been meticulously engineered in a 3D acoustic crystal, facilitating the creation of 3D flat bands through Landau quantization of quasiparticles arising from nodal-ring band degeneracies.

Cotton fibre is the most important renewable material for textiles, with a huge economic output. Here the authors show that a homeodomain-leucine zipper transcription factor, GhHOX3, transduces a gibberellin signal that in turn promotes fibre cell elongation.

Glucagon-like peptide 1 (GLP1) is processed and cleaved from proglucagon to stimulate insulin secretion. Here, authors show that Nogo-B interacts with proglucagon to retain it on the ER, thereby inhibiting PCSK1-mediated cleavage of proglucagon and secretion of GLP1.

The quality of covalent organic frameworks is often compromised by structural damages induced during their activation procedure which influences their subsequent applications. Here, the authors describe a self-sacrificing guest strategy to synthesize high-quality two-dimensional COFs by incorporating salt guests within the pores of the COF structure.

Oncolytic viruses can activate tumor neoantigen-specific T cell responses. However, PD-L1 upregulation on tumor cells and immune cells leads to tumor resistance to this immunotherapy approach. Here, the authors develop an oncolytic virus which expresses both a PD-L1 inhibitor and GM-CSF which allows an improved tumor neoantigen-specific T cell response in preclinical models.
