In the technological scenarios where social media and artificial intelligence are popularized，low-quality scientific and health information has become an important object for the collaborative governance of false information，which poses higher requirements for the knowledge and skills of Internet users who serve as one of the main bodies of collaborative governance. To investigate the role of digital news literacy and its sub-dimensions in reducing the preference for unofficial media trust among individuals with different levels of scientific trust，this paper conducted an online survey based on a quota sample of Chinese netizens（N=1 109）. Research has found that those with higher literacy in the context，content，circulation，and consumption of digital news，as well as overall literacy，are more likely to break the reliance on unofficial information channels，and this mechanism is more effective among scientific believers. The research has broken the theoretical myth of “trust nexus”；as a differentiated path for the whole society to enhance digital news literacy and govern disinformation，the study suggests disseminating social science knowledge，such as media effects and media systems to science believers，and emphasizing how news differs from non-news and the process of news production to science skeptics.

Deep synthesis technologies，exemplified by DeepSeek，are injecting powerful momentum into modern science communication，guiding the public’s understanding of science into a new normal. They are propelling public cognitive paradigms from “tool-assisted” to a novel stage of “cognitive enhancement”. However，this technological leap is not entirely smooth. While presenting numerous opportunities，it also harbors cognitive risks. This inherent tension reveals that while the public benefits from enhanced cognitive efficiency，expanded cognitive horizons，and transformed knowledge transmission paradigms through algorithmic tools like DeepSeek，they simultaneously face risks of cognitive displacement which includes systemic degradation of critical thinking，pathological fixation of cognitive dependencies，and hierarchical rigidification of cognitive disparities due to “cognitive outsourcing”. Faced with the technological empowerment value and potential cognitive risks demonstrated by tools like DeepSeek in AI science popularization，we must pursue a rational dialectical thinking dimension to advance development，constructe a three-dimensional collaborative framework integrating technology，cognition，and ethics. By restructuring critical thinking training mechanisms，refining technical usage standards，and strengthening social equity safeguards，we can foster a new ecosystem for AI science communication characterized by human-machine symbiosis and inclusive sharing，ensure technological capabilities genuinely serve the comprehensive development of the public as DeepSeek and similar deep synthesis service algorithms integrate with modern science communication.

Scientific literacy underpins national technological innovation and sustainable development，with the efficacy of science popularization directly influencing a nation’s overall scientific literacy. China has always attached great importance to the science popularization，and since the beginning of the 21st century，the promulgation of a series of important policies and documents and the establishment of mechanisms for the science popularization have led to the important development of the cause of science popularization. In the new era，the connotation，concept and means of science popularization have undergone significant changes，and science popularization is facing many challenges，including insufficient understanding of the importance of science popularization，insufficient supply of high-quality science popularization，the urgent need to improve the system of collaborative work in the society of science popularization and the need to strengthen the venues for science popularization，etc. In view of this，the latest progress and experience of science popularization in the international arena will be useful for China to enhance the effectiveness of science popularization. This paper takes the United Kingdom，the United States，Japan，Australia and the European Union as the research objects，and conducts in-depth research and comparative analysis on the science popularization systems in these countries and regions from 2017 to 2024 by constructing a multi-dimensional analytical framework of “theory-policy-technology-practice-public participation”，aiming at grasping the cutting-edge dynamics of the development of science popularization in the international arena. It is found that these developed countries and regions have the following distinctive features in the field of science popularization：theoretical inquiry shows a trend of paradigm change and synergy of subjects，policy making focuses on educational integration and differentiated response，technological development and application and cognitive reflection，practical path focuses on multi-dimensional expansion and continuous deepening，and public participation highlights equal interaction and multi-party linkage. Based on the current situation of science popularization in China，this paper proposes that China should build a multi-dimensional optimization path with its own characteristics.

The application of generative artificial intelligence in the field of science writing is burgeoning. While empowering science writing，it also introduces unique challenges，such as scientific inaccuracies of science popularization works，the identity and ability recognition of science writers，and the “limited autonomy” of the audience under the implicit dominance of technology. It is suggested to guide the responsible and sustainable development of generative AI-assisted science writing from several aspects：Adhering to the bottom line of the scientificity of science popularization works；Strengthening the subjectivity of “human” of science writers and emphasizing the organic integration of instrumental rationality and value rationality；Enhancing the scientific and digital literacy of the public and creating a new environment for science writing that suits the current situation.

As the pace of global digital transformation accelerates，digital literacy has emerged as a cornerstone for enhancing citizens’ overall competence and bolstering national competitiveness. By analyzing and comparing strategies and policies for enhancing digital literacy in five representative countries/regions—the United States，the European Union，the United Kingdom，Singapore，and Japan-this paper proposes targeted recommendations for advancing China’s nationwide digital literacy.The study finds six elements consistently underpin these national strategies that regular evaluation of strategic progress，robust digital infrastructure，comprehensive digital-literacy frameworks，sustained cultivation of digital talent，wide-ranging digital-skills training programs，and multi-stakeholder cooperation mechanisms. Looking ahead，China should refine its development goals and supporting measures，continue to expand and upgrade its digital infrastructure，establish a national digital-literacy assessment framework and corresponding curriculum system，enhance digital services for vulnerable groups，strengthen the digital-talent pipeline，and foster closer collaboration among government，industry，academia，and civil society.

To enhance the China Science and Technology Museum（CSTM）visitor satisfaction，This reseanh constructs a structural model to inquire into the interaction mechanism among visitor expectations，perceived quality，perceived value，visitor satisfaction，and visitor loyalty. During the periol from August to October 2024，the research team conducted a survey among CSTM visitors，the results show that perceived quality and perceived value have a significant positive impact on visitor satisfaction，while，visitor expectations exert a relatively weak influence on visitor satisfaction. Furthermore，visitor satisfaction was found to have a positive effect on visitor loyalty. Therefore，CSTM should focus on enhancing perceived quality and perceived value.

As the core ability of citizens to effectively participate in digital life，digital literacy has become a key indicator of national competitiveness. This paper systematically reviewed representative international and domestic definitions of digital literacy and distilled their underlying theoretical orientations，thereby illuminating the conceptual evolution of digital literacy. It aims to develop a theoretical system and practical mechanism of digital literacy with local characteristics. This study shows that the connotation of digital literacy has shifted from instrumental competence to a comprehensive competence system covering critical thinking and security. Current research shows three major trends，including conceptual expansion，exacerbation of the literacy divide，and the rise of algorithmic and AI literacy. In the future，it is imperative to develop a local digital literacy theoretical system and an education ecosystem involving multi-stakeholder collaboration，thereby responding to the new requirements in digital society.

The arrival of the platform society poses new challenges to traditional citizens’ digital literacy，reflected in both visually-centred forms of content expression and algorithmically-driven mechanisms of content distribution. Based on an analysis of visual studies and platform studies，this paper argues that digital literacy in the platform society comprises two key dimensions：visual literacy and algorithmic literacy. Enhancing citizens’ digital literacy requires developing both visual interpretation，critique，and creative abilities, as well as algorithmic cognition，critique，and interactive abilities. Furthermore，it emphasizes that the collaborative enhancement of digital literacy in the platform society should be grounded in structural empowerment，guided by inclusiveness，and oriented toward future technological transformations.

Citizens’ digital literacy and skills are closely linked to personal survival and development，social equity and inclusiveness，and national economic development. Conducting relevant evaluations is an inevitable requirement for promoting the sustainable development of the digital society. This paper reviews the research progress and practical status of citizens’ digital literacy and skills in terms of evaluation concepts and frameworks，evaluation methods and tools. By comparing the characteristics of different evaluation systems through evaluation cases，it clarifies the problems and challenges faced by evaluations and looks forward to the future trends of intelligent，precise，and standardized evaluations.

The national science popularization system and the construction of national science popularization capacity are of great significance for continuously improving the scientific literacy of the entire population，achieving high-level scientific and technological self-reliance and self- improvement，meeting the people’s ever-growing demand for scientific life，and comprehensively building a strong country in science and technology. This article explores the conceptual connotations of the national science popularization system and national science popularization capacity from the meta-concepts of“system”and“capability”. That is，the national science popularization system and national science popularization capacity are a concentrated reflection of a country’s entire set of systematic arrangements and comprehensive strength regarding science popularization. From the perspective of“structure-function”，this article systematically examines the diverse logical relationships between the two. The national science popularization system is the front-end structural construction，while the national science popularization capacity is the post-functional embodiment. The two are composed of a closely coordinated and functionally embedded complementary relationship. Based on this institutionalized logical approach，a set of efficiency improvement paths is proposed，including policies on science popularization，subjects of science popularization，diverse safeguard mechanisms for science popularization investment，management mechanisms combining supervision and incentives，and international science popularization exchange mechanisms.
