Recent advances in multimodal large language models unlock unprecedented opportunities for GUI automation. However, a fundamental challenge remains: how to efficiently acquire high-quality training data while maintaining annotation reliability? We introduce a self-evolving training pipeline powered by the Calibrated Step Reward System, which converts model-generated trajectories into reliable training signals through trajectory-level calibration, achieving >90% annotation accuracy with 10-100x lower cost. Leveraging this pipeline, we introduce Step-GUI, a family of models (4B/8B) that achieves state-of-the-art GUI performance (8B: 80.2% AndroidWorld, 48.5% OSWorld, 62.6% ScreenShot-Pro) while maintaining robust general capabilities. As GUI agent capabilities improve, practical deployment demands standardized interfaces across heterogeneous devices while protecting user privacy. To this end, we propose GUI-MCP, the first Model Context Protocol for GUI automation with hierarchical architecture that combines low-level atomic operations and high-level task delegation to local specialist models, enabling high-privacy execution where sensitive data stays on-device. Finally, to assess whether agents can handle authentic everyday usage, we introduce AndroidDaily, a benchmark grounded in real-world mobile usage patterns with 3146 static actions and 235 end-to-end tasks across high-frequency daily scenarios (8B: static 89.91%, end-to-end 52.50%). Our work advances the development of practical GUI agents and demonstrates strong potential for real-world deployment in everyday digital interactions.

Radiation absorbers have increasingly been attracting attention as crucial components for controllable thermal emission, energy harvesting, modulators, etc. However, it is still challenging to realize thin absorbers which can operate over a wide spectrum range. Here, we propose and experimentally demonstrate thin, broadband, polarization-insensitive and omnidirectional absorbers working in the near-infrared range. We choose titanium (Ti) instead of the commonly used gold (Au) to construct nano-disk arrays on the top of a silicon dioxide (SiO 2 ) coated Au substrate, with the quality (Q) factor of the localized surface plasmon (LSP) resonance being decreased due to the intrinsic high loss of Ti. The combination of this low-Q LSP resonance and the propagating surface plasmon (PSP) excitation resonance, which occur at different wavelengths, is the fundamental origin of the broadband absorption. The measured (at normal light incidence) absorption is over 90% in the wavelength range from 900 nm to 1825 nm, with high absorption persisting up to the incident angle of ~40°. The demonstrated thin-film absorber configuration is relatively easy to fabricate and can be realized with other properly selected materials.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease frequently accompanied by intestinal barrier dysfunction and gut microbiome dysbiosis. Emerging evidence suggests that these impairments can contribute to secondary liver injury (SLI) by disrupting the gut–liver axis and promoting hepatic inflammation. Gentiopicroside (GPS), a natural iridoid glycoside, possesses antimicrobial, anti-inflammatory, and hepatoprotective properties. This study aimed to evaluate the protective effects and underlying mechanisms of GPS in a dextran sulfate sodium (DSS)-induced mouse model of UC and associated SLI. Mice were evaluated for body weight, Disease Activity Index (DAI), colon length, histopathology, tight junction protein expression, gut microbiota composition, inflammatory cytokine levels, and liver function biomarkers. GPS significantly alleviated weight loss, reduced DAI scores, restored intestinal tight junction protein expression, and improved colonic permeability. GPS also modulated the gut microbiota, notably increasing beneficial Bacteroides and Clostridium cluster IV. Mechanistically, GPS suppressed colonic and hepatic inflammation by inhibiting the TLR4/MyD88/NF-κB and JAK2/STAT3 signaling pathways. Moreover, GPS improved liver function and reduced hepatic inflammatory markers, indicating mitigation of SLI. In conclusion, GPS exerts protective effects against DSS-induced UC and SLI by enhancing intestinal barrier integrity, modulating the gut microbiome, and attenuating inflammation via the gut–liver axis.

Advanced oxidation technology represented by hydroxyl radicals has great potential to remove residual antibiotics. In this study, we systematically compared the metronidazole (MTZ) degradation behavior and mechanism in the UV and UV/H2O2 systems at pH 3.00 condition. The results show that the initial reaction rates were 0.147 and 1.47 µM min−1 in the UV and UV/H2O2 systems, respectively. The main reason for the slow direct photolysis of MTZ is the relatively low molar absorption coefficient (2645.44 M−1 cm−1) and quantum yield (5.9 × 10−3 mol Einstein−1). Then, we measured kMTZ,OH • as 2.79 (±0.12) × 109 M−1 s−1 by competitive kinetics, and calculated kMTZ,OH • and [OH •]SS as 2.43 (±0.11) × 109 M−1 s−1 and 2.36 × 10−13 M by establishing a kinetic model based on the steady-state hypothesis in our UV/H2O2 system. The contribution of direct photolysis and •OH to the MTZ degradation was 9.9% and 90.1%. •OH plays a major role in the MTZ degradation, and •OH was the main active material in the UV/H2O2 system. This result was also confirmed by MTZ degradation and radicals’ identification experiments. MTZ degradation increases with H2O2 dosage, but excessive H2O2 had the opposite effect. A complex matrix has influence on MTZ degradation. Organic matter could inhibit the degradation of MTZ, and the quenching of the radical was the main reason. NO3− promoted the MTZ degradation, while SO42− and Cl− had no effect. These results are of fundamental and practical importance in understanding the MTZ degradation, and to help select preferred processes for the optimal removal of antibiotics in natural water bodies, such as rivers, lakes, and groundwater

Highlights A transparent and ceramizable coating was developed by incorporating nano-layered double hydroxide nanosheets into hierarchical hydrogen bonding polymer networks. The resulting coating composites demonstrated excellent high-temperature stability and fire resistance, effectively withstanding the direct exposure to a butane flame (~ 1100 °C) in air atmosphere. The mechanisms behind the flame-retardant behavior and ceramicization behaviors were thoroughly investigated and explained. In recent decades, annual urban fire incidents, including those involving ancient wooden buildings burned, transportation, and solar panels, have increased, leading to significant loss of human life and property. Addressing this issue without altering the surface morphology or interfering with optical behavior of flammable materials poses a substantial challenge. Herein, we present a transparent, low thickness, ceramifiable nanosystem coating composed of a highly adhesive base (poly(SSS 1 -co-HEMA 1 )), nanoscale layered double hydroxide sheets as ceramic precursors, and supramolecular melamine di-borate as an accelerator. We demonstrate that this hybrid coating can transform into a porous, fire-resistant protective layer with a highly thermostable vitreous phase upon exposure to flame/heat source. A nanosystem coating of just ~ 100 μm thickness can significantly increase the limiting oxygen index of wood (Pine) to 37.3%, dramatically reduce total heat release by 78.6%, and maintain low smoke toxicity (CIT G  = 0.016). Detailed molecular force analysis, combined with a comprehensive examination of the underlying flame-retardant mechanisms, underscores the effectiveness of this coating. This work offers a strategy for creating efficient, environmentally friendly coatings with fire safety applications across various industries.

The activation of persulfate has received considerable attention for its potential application in the removal of pollutants. In recent years, various technologies have been developed to catalyze its activity, which can be classified into two main methods: homogeneous and non-homogeneous activation. Homogeneous activation methods encompass thermal activation, photoactivation, ultrasonic activation, electrical activation, microwave activation, and transition metal ion activation. What is more, non-homogeneous activation methods include activation through metal-based nanomaterials, MOF material activation, single-atom catalysts, piezoelectric effect activation, and carbon activation. In this review, it presents a comprehensive overview about the advantages and disadvantages of these activation methods, as well as the main reaction mechanisms. Additionally, chemical identification methods such as quenching, chemical probes, and isotope techniques are discussed. Furthermore, the article explores two characterization methods, electron paramagnetic resonance, in situ Fourier transform infrared spectroscopy and Raman spectroscopy, and mass spectrometry, and their application in experimental studies. Finally, the current limitations of each technique and future research directions are discussed and prospected. This article aims to provide valuable insights into the various activation methods of persulfate and their applications in the field of environmental science and technology.

Despite enormous efforts, copper corrosion remains a key inducement causing huge economic losses in electrical, construction, and military industries, and deteriorates the performance of semiconductor devices. Here we show that a set of ligands functionalized with both catechol and aromatic amine groups achieves environmentally-adaptive copper passivation and fully preserves the intrinsic electrical and thermal conductivities of copper and its alloys. The oxidation of ligands in corrosive environments causes the structure-adaptation of the passivation layer, further enhancing the corrosion resistance to harsh environments including alkali and salt solutions, thermal treatment, and UV-light- and oxygen-enriched conditions. Simply adsorbing these ligands on the surface of copper, brass, copper powder, copper-based flexible printed circuits, and copper inks for flexible electronics results in strong liquid and air anticorrosion performances. Our copper passivation technique only requires a room temperature soaking procedure, providing a high industrialization possibility for copper protection, particularly in semiconductor electronics and flexible electronics. A ligand oxidation structure-adaptive strategy creates an ultra-thin passivation nanolayer that enables copper and its alloys to resist corrosion and oxidation in harsh environments while retaining intrinsic electrical and thermal conductivities.

CD4 + and CD8 + double-positive (DP) thymocytes play a crucial role in T cell development in the thymus. DP cells rearrange the T cell receptor gene Tcra to generate T cell receptors with TCRβ. DP cells differentiate into CD4 or CD8 single-positive (SP) thymocytes, regulatory T cells, or invariant nature kill T cells (iNKT) in response to TCR signaling. Chromatin organizer SATB1 is highly expressed in DP cells and is essential in regulating Tcra rearrangement and differentiation of DP cells. Here we explored the mechanism of SATB1 orchestrating gene expression in DP cells. Single-cell RNA sequencing shows that Satb1 deletion changes the cell identity of DP thymocytes and down-regulates genes specifically and highly expressed in DP cells. Super-enhancers regulate the expressions of DP-specific genes, and our Hi-C data show that SATB1 deficiency in thymocytes reduces super-enhancer activity by specifically decreasing interactions among super-enhancers and between super-enhancers and promoters. Our results reveal that SATB1 plays a critical role in thymocyte development to promote the establishment of DP cell identity by globally regulating super-enhancers of DP cells at the chromatin architectural level. Here the authors show the identity of CD4 + CD8 + double-positive (DP) thymocytes changes upon loss of chromatin organizer Satb1, which controls the expression of cell identity genes by regulating super-enhancers via 3D genome architecture.

Non-small cell lung cancer (NSCLC) remains a leading cause of cancer mortality worldwide. Platinum-based chemotherapy is standard-of-care but has limitations including toxicity and resistance. Metal complexes of gold, ruthenium, and other metals have emerged as promising alternatives. This review provides a comprehensive analysis of metallodrugs for NSCLC. Bibliometric analysis reveals growing interest in elucidating mechanisms, developing targeted therapies, and synergistic combinations. Classification of metallodrugs highlights platinum, gold, and ruthenium compounds, as well as emerging metals. Diverse mechanisms include DNA damage, redox modulation, and immunomodulation. Preclinical studies demonstrate cytotoxicity and antitumor effects in vitro and in vivo , providing proof-of-concept. Clinical trials indicate platinums have utility but resistance remains problematic. Non-platinum metallodrugs exhibit favorable safety but modest single agent efficacy to date. Drug delivery approaches like nanoparticles show potential to enhance therapeutic index. Future directions include optimization of metal-based complexes, elucidation of resistance mechanisms, biomarker development, and combination therapies to fully realize the promise of metallodrugs for NSCLC.
