Osteoarthritis is a marked by cartilage loss and limited by the absence of effective disease modifying treatments. Here, the authors show that orphan nuclear receptor small heterodimer partner (SHP) protects cartilage by suppressing IKKβ dependent NF κB signaling, highlighting it as a potential therapeutic target.

Cell death induced by metal ions is promising for cancer immunotherapy but sometimes limited by effective loading/release into tumor sites. Here this group reports a binary mineral nanoparticles incorporating both Ca2+ and Na+ ions to enhance the cytotoxic effects of ion interference in cancer immunotherapy.

Eukaryotic algae and cyanobacteria can produce hydrogen in the presence of little or no oxygen. Here, the authors show that two microalgal strains are capable of producing hydrogen under aerobic conditions, and provide new insights into the natural evolution of oxygen-tolerant hydrogenase.

The absence of a band gap in graphene hinders its use in electronics. Here, the authors open a band gap as large as 3.9 electronvolts in graphene grown by chemical vapour deposition by treating it in hydrogen plasma, and then use this material to create a room temperature field- effect transistor.

Identifying the mechanisms underlying the early inflammatory phase of aortic valve disease is crucial for disease prevention. Here the authors perform single-cell RNA sequencing to show the immunomodulatory role of PPARγ in valvular endothelial cells during hyperlipidemia.

Microbiome-secreted proteins act as key modulators of host-microbiome crosstalk. Here, the authors show that Amuc_1409 protein, secreted from Akkermansia muciniphila, plays a key role in intestinal homeostasis by regulating intestinal stem cells through interaction with E-cadherin, indicating its potential as a biomolecule for improving gut health.

Occurrence of DNA double-strand break (DSB) repair is important for genome integrity. Here, the authors reveal that Pellino1 is a DSB-responsive ubiquitin ligase required for promoting the accumulation of ATM and MRN complex at DSB sites via NBS1 ubiquitination.

Mechanochemistry offers a paradigm shift by enabling ammonia synthesis under near-ambient conditions. Here, the authors present an innovative mechanochemical approach that employs silicon nitride as a defect-inducing physical promoter to facilitate ammonia production.

The deprivation of amino acids in the tumor microenvironment affects T cell survival and activation. Here the authors show that reduced levels of methionine are associated with PD1 upregulation in CD4+ T cells and that methionine supplementation promotes CD4+ T cell dependent anti-tumor immune responses.

GI forms an inactive nuclear condensate that is dispersed at high temperatures by FKF1 binding to GI’s intrinsically disordered region. The resulting FKF1–GI complex promotes SVP degradation, accelerating flowering at high ambient temperatures.

The emergence of cisplatin resistance and side-effects are important factors in cancer treatment failure. Here, the authors identify autophagy-mediated EGFR hyperactivation by TRPV1 promotion as a mechanism of cisplatin resistance and demonstrate the efficacy of a TRPV1 inhibitor to sensitize lung cancer to cisplatin.

Williams and colleagues investigate the origin, dynamics and transcriptional profiles of aortic intima macrophages during atherosclerosis disease progression.

tRNA synthetases are essential to protein synthesis. Kim and colleagues identify a non-translational function for glutamyl-prolyl-tRNA synthetase during viral infection that promotes the anti-viral activity of the antiviral signaling protein MAVS.

The underlying mechanism behind charge density wave formation in Kagome metals is still not fully understood. Here, the authors propose that the phonon modes become frustrated in the charge density wave phase of CsV₃Sb₅.

In ambient conditions, the detection of topological surface states in topological insulators is impaired by the presence of bulk and quantum well states. Here, Park et al. demonstrate how such topological states in epitaxial ultrathin Bi₂Se₃may be isolated using terahertz time-domain spectroscopy.

RNA viral infections trigger an immune response mediated by the formation of aggregates of the MAVS protein. Here the authors show that the mitochondrial protein MARCH5 modulates this response by transferring ubiquitin to MAVS aggregates, thus promoting their proteasomal degradation.

The adaptability of the plant Arabidopsis thaliana to different temperatures is regulated by the ability of its ELF3 protein to undergo liquid–liquid phase separation, in a manner that is dependent on the protein’s prion-like domain.

Nanog can confer resistance to cancer immunotherapy by promoting AKT activity. Here, the authors demonstrate that HSP90A is a Nanog target that stabilizes the AKT coactivator TCL1, thereby activating AKT, and that HSP90A inhibition can enhance the anti-tumor efficacy of adoptive T cell transfer and checkpoint blockade.

Experiments that directly probe the quantum geometric tensor in solids have not been reported. Now, the quantum metric and spin Berry curvature—dual components of the quantum geometric tensor—have been simultaneously measured in reciprocal space.

Recruiting DNA damage repair factors to the sites of DNA damage is critical for the maintenance of genome integrity. Here the authors identify that the TRAF-interacting protein (TRAIP/RNF206) is required for normal recruitment of RAP80 to DNA lesions and the stimulation of homologous recombination.

Retnla is an adipokine with known roles in tissue repair and inflammation. Here Lee et al. show that Retnla also promotes cholesterol metabolism and excretion, thereby lowering blood cholesterol levels and reducing the development of atherosclerosis in mice.

The strong interaction between electron spin and orbital degrees of freedom in 5d oxides can lead to exotic electronic ground states. Here the authors use resonant inelastic X-ray scattering to demonstrate that the theoretically proposed J _eff = 3/2 state is realised in GaTa₄Se₈.

Spectroscopic measurements show how the features of the band structure related to the kagome lattice in CsV₃Sb₅ contribute to the observed strongly correlated phases.

Samples of different body regions from hundreds of human donors are used to study how genetic variation influences gene expression levels in 44 disease-relevant tissues.

A wireless monitoring system that integrates an organic electrochemical transistor and a near-infrared inorganic micro-light-emitting diode on a thin parylene substrate can be used to monitor biomarkers such as glucose, lactate and pH.

Magnets with frustrated interactions are predicted to form quantum entangled states that feature measurable plateaus in their magnetization. Evidence for one of these plateau phases has now been found in a kagome lattice antiferromagnet.

The PIF4 transcription factor promotes stem elongation by inducing auxin biosynthesis at elevated temperature in Arabidopsis. Here, Lee et al.show that the RNA-binding protein FCA attenuates PIF4 activity by promoting its dissociation from the promoter of a gene encoding an auxin biosynthetic enzyme.

Magnetoelectric materials combine ferroelectric and magnetic properties through a coupling of the spin and lattice degrees of freedom. Here, magnetoelectric bismuth ferrite is found to simultaneously undergo both a magnetic and a ferroelectric transition at the same temperature.

Linking protein components in a controlled manner is crucial for assembling protein nanostructures with pre-determined architecture. Here, the authors use a chemical cross-linker to fuse the terminal helices of two proteins into a single one, forcing the protein domains in a specific orientation.
