Evaluation of rural comprehensive development level and obstacle factors in various countries around the world
At present, major developing countries in the world are entering a stage of rapid urbanization, and rural transformation and development are accelerating. Conducting international comparisons of rural development, evaluating and diagnose rural development levels of various countries and summarizing the advantages of rural areas in developed countries. These summaries and comparisons are important for developing countries to implement rural revitalization and promote the transformation of rural regional systems. Basing on the connotation of rural development, this study constructs an evaluation index system for rural development level worldwide. Through AHP-entropy method, TOPSIS method, obstacle model, and regression model, this study analyzes the rural comprehensive development level of 175 countries and regions and obstacle factors on the basis of statistical data from the United Nations and World Bank. Results suggest significant differences in the comprehensive development level of rural areas among countries at the global level. In addition. The comprehensive development level of rural areas exhibits definite correlations with national income level, per capita GDP, and the Human Development Index (HDI), among which it shows the weakest correlation with the level of urbanization. The main obstacle factors to rural development in various countries are agricultural mechanization level, agricultural land output rate, average per labor of cultivated land area, number of doctors per thousand, and per capita income of farmers. The factors affecting the rural development level are resource endowment, economic development level, education level, and government support for agriculture. Based on the research findings, this study proposes strategic recommendations for improving the rural comprehensive development level from the perspectives of agricultural and rural development and the living standards of farmers.

Economic suitability of direct seeded rice across different geographies in India
Puddled transplanted rice (PTR) is being replaced by dry direct-seeded rice (dDSR) to address manpower, water, and agricultural costs. The economic suitability of dDSR in different agro-climatic regions limits its widespread adoption. We use plot and household data to estimate the impact of dDSR adoption in four Indian rice-growing states. We first used propensity score matching (PSM) to assess how dDSR adoption affected operation-wise cultivation costs, paddy yield, and net income. The yield effect on DSR adoption was estimated using endogenous switch regression (ESR) to account for observed and unobserved heterogeneity. Both PSM and ESR-based results show that DSR adoption may increase paddy yield in Uttar Pradesh, Andhra Pradesh, and Telangana and decrease it in Madhya Pradesh, but net income from paddy farming increased significantly (Rs5009/acre to 8134 based on different locations) in all four states. Adopting dDSR helps resource-poor Indian farmers reduce paddy production costs and increase income. Therefore, Central and State governments must implement policies and strategies to encourage non-adopters to adopt dDSR.

Organic magnetic nanoparticles catalyze CO2 capture in hydrogen-bonded nanocages via water-driven crystallization
Abstract Limiting global warming increasingly relies on the development of environmentally friendly CO2 capture strategies. Crystallization is renowned for versatile separation and purification, yet traditional compound crystallization-based CO2 capture still necessitates intricate preparation processes, stringent reaction conditions, and high regenerative energy consumption. As an ambitious sustainability goal, natural water could be used as a precursor of crystallization to construct hydrogen-bonded water cages for CO2 capture, but main obstacles are slow crystallization kinetics and low capture capacity. Here, a water-activation-induced crystallization strategy by organic magnetic nanoparticles (Methionine@Fe3O4) has been proposed for efficient CO2 capture. Local water ordering strengthened by hydrophobic amino acids and abundant nucleation sites provided by nanoparticles create hotspots for hydration phase transition and crystal growth, with a CO2 capture capacity of 118.7 v/v (22.7 wt%). Favorable biocompatibility and stable performance are conducive to the industrial application of this nanomaterial, and the excellent magnetic recyclable property enables simple separation from clean water. This strategy demonstrates an extraordinary CO2 capture potential compared to state-of-the-art systems, thus providing an inspiration for sustainable CO2 capture and storage with zero resource depletion (ZRD).

Structural mechanism of FusB-mediated rescue from fusidic acid inhibition of protein synthesis
Abstract The antibiotic resistance protein FusB rescues protein synthesis from inhibition by fusidic acid (FA), which locks elongation factor G (EF-G) to the ribosome after GTP hydrolysis. Here, we present time-resolved single–particle cryo-EM structures explaining the mechanism of FusB-mediated rescue. FusB binds to the FA-trapped EF-G on the ribosome, causing large-scale conformational changes of EF-G that break interactions with the ribosome, tRNA, and mRNA. This leads to dissociation of EF-G from the ribosome, followed by FA release. We also observe two independent binding sites of FusB on the classical-state ribosome, overlapping with the binding site of EF-G to each of the ribosomal subunits, yet not inhibiting tRNA delivery. The affinity of FusB to the ribosome and the concentration of FusB in S. aureus during FusB-mediated resistance support that direct binding of FusB to ribosomes could occur in the cell. Our results reveal an intricate resistance mechanism involving specific interactions of FusB with both EF-G and the ribosome, and a non-canonical release pathway of EF-G.
Gama rays mediated improvement of catalytic efficiency and thermostability of glucoamylase by replacing active site leucine to isoleucene from super koji (Aspergillus oryzae)
Glucoamylase is considered as an essential enzyme in food industry. However, lowere catalytic efficiency and weak thermostability confine its application in food industry. Therefore, the current study was aimed to improve catalytic efficiency and thermostability of glucoamylase by replacing active site leucine to isoleucene from Super Koji (Aspergillus oryzae) using gama rays mediated point mutation. High catalytic efficiency and thermostability of glucoamylase from mutant Aspergillus oryzae M-60(5) (screened from 51 mutants) was achieved due to a point mutation, i.e., Leu203 → lle in active site. The SDS-PAGE molecular mass of parent and mutant glucoamylase was 63.1 kDa, while mutant glucoamylase showed; productivity = 9.7 U ml‒1, kinetic constants kcat = 118 (1.62 fold), (kcat/Km) = 1899 (4.75 fold) and half-life at 55 °C for 45 min (1.92 fold). Thermodynamics parameters for starch hydrolysis of parent glucoamylase were; ΔH*= 47.755 kJ mol‒1 and ΔG*= 67.975 kJ mol‒1 while for mutant ΔH*= 44.263kJ mol‒1 and ΔG*= 66.514 kJ mol‒1. The ΔG* of irreversible thermostability for parent and mutant at 55 °C was 104.95 kJ mol‒1 and 101.52 kJ mol‒1respectively. The point mutation altered the conformation of the glucoamylase active site that contributed to improve the functional energy (ΔG*), resulted the stabilization of transition state which made it thermostable and highly efficient in starch hydrolysis.

Earth system instability amplified biogeochemical oscillations following the end-Permian mass extinction
Abstract After the end-Permian mass extinction, the Earth system underwent extreme ecological and environmental fluctuations, including high temperatures, recurrent oceanic anoxia, and carbon cycle oscillations as demonstrated by the geochemical isotope proxy records. However, the underlying mechanism behind these oscillations remains poorly understood. Here we propose that they were produced by a coupled oscillation mode of marine phosphorus ( P ) and atmosphere–ocean carbon ( A ), driven by nonlinear redox controls on marine phosphorus burial. Our modeling demonstrates that the initial emplacement of the Siberian Traps and the mass extinction (on land and in the ocean) directly led to an early Triassic greenhouse. More importantly, it homogenized the ocean floor redox condition towards anoxia, activating amplifying feedbacks and destabilizing the system. The internal dynamics of an unstable system—rather than recurrent volcanic shocks—triggered the periodic oscillations (limit cycles) of serial excursions in carbonate carbon and uranium isotopes during the early Triassic.

Zygotic activation of transposable elements during zebrafish early embryogenesis
Abstract Although previous studies have shown that transposable elements (TEs) are conservatively activated to play key roles during early embryonic development, the details of zygotic TE activation (ZTA) remain poorly understood. Here, we employ long-read sequencing to precisely identify that only a small subset of TE loci are activated among numerous copies, allowing us to map their hierarchical transcriptional cascades at the single-locus and single-transcript level. Despite the heterogeneity of ZTA across family, subfamily, locus, and transcript levels, our findings reveal that ZTA follows a markedly different pattern from conventional zygotic gene activation (ZGA): ZTA occurs significantly later than ZGA and shows a pronounced bias for nuclear localization of TE transcripts. This study advances our understanding of TE activation by providing a high-resolution view of TE copies and creating a comprehensive catalog of thousands of previously unannotated transcripts and genes that are activated during early zebrafish embryogenesis. Among these genes, we highlight two that are essential for zebrafish development.

A simulation-driven computational framework for adaptive energy-efficient optimization in machine learning-based intrusion detection systems
Abstract This paper presents GreenMU, an innovative proposed novel framework designed to address the two main challenges: energy efficiency as one of the main research components and detection performance in intrusion detection systems. In the proposed research paper study, by integrating advanced machine learning techniques such as random forest classifier and support vector machines classifier with knowledge distillation and adaptive energy-aware optimization, GreenMU achieves a balanced trade-off between computational efficiency and cybersecurity accuracy. The proposed MUGuard algorithm is at the framework’s core, which dynamically adjusts computational complexity based on real-time actual energy constraints and the evolving threat landscape. Extensive simulations conducted on the KDD 1999 dataset demonstrate that GreenMU achieves a detection accuracy close to 99%, significantly surpassing standard baseline models while reducing energy consumption by 31%. Furthermore, the framework improves computational efficiency, reducing processing time by 15% and making it highly effective for resource-constrained environments such as IoT and edge computing. This research paper study highlights the potential of green artificial intelligence in advancing cybersecurity, providing a scalable, sustainable, and high-performing solution to modern intrusion detection challenges.

The demographic characteristics and prognosis of acute myeloid leukemia with t(3;3)/inv(3) in the united states: a SEER-based study
Abstract Acute myeloid leukemia (AML) with t(3;3) (q21; q26.2) or inv(3) (q21; q26.2) is a rare subtype of acute myeloid leukemia with a poor prognosis. Research on the demographic characteristics and clinical outcomes of AML patients with t(3;3) (q21; q26.2) or inv(3) (q21; q26.2) is limited. All AML patients diagnosed with t(3;3) (q21; q26.2) or inv(3) (q21; q26.2) between 2000 and 2021 from SEER (Surveillance, Epidemiology, and End Results Program) database were included in this study. Survival analysis was performed using the Kaplan–Meier method. The log-rank test was used to analyze the significance of differences between overall survival (OS) and cancer-specific survival (CSS). Due to being a retrospective study, the limited amount of baseline characteristics available, and the missing information on treatments and recurrence, the provided dataset is not exactly representative for the US population. The median age of the total 90 AML patients with t(3;3) (q21; q26.2) or inv(3) (q21; q26.2) was 65(49–74) years old. Among them, 57.78% were married and non-Hispanic whites accounted for 74.44%. 84.44% of the patients received chemotherapy. The median OS was 8 months, and the median CSS was 10 months. The 5-year survival rate for OS was 15.29% (95%CI:7.98-24.78%), and 20.05% (95%CI:10.69–31.51%) for CSS. The OS and CSS of patients above 60 years were inferior to those of patients under 60 years. Single (never-married) patients had better OS and CSS than those with other marital status. Age and marital status at diagnosis were independent influencing factors for OS and CSS based on the multivariate COX regression analysis. AML with t(3;3) (q21; q26.2) or inv(3) (q21; q26.2) mostly occurs in adults and has poor clinical outcomes with worse OS and CSS, especially in the elderly.
