The emergence and rapid development of generative artificial intelligence（GenAI）have greatly changed the current science popularization ecology. It not only effectively empowers current science popularzation creators，making the production of science popularization content more convenient and faster，but also directly intervenes in the current socialized collaborative science popularization pattern as a non-human actor. To better realize the benign intervention of GenAI in the current ecological pattern of science popularization，it is first necessary to systematically analyze its strategy bias as a science communicator when generating science popularization content and the possible differences between its science popularization strategy use and that of human science popularization creators. Based on the method of algorithm auditing，this paper finds，through coding and analyzing the science popularization content that representative GenAI tools generated at home and abroad，that GenAI has indeed adopted a series of diversified discourse strategies when producing science communicators，and there are certain differences between the discourse strategies adopted and those of human science communicators. Overall，it presents a characteristic of being inclined to be microcosmic and having an ambiguous identity. There are also considerable differences in the discourse strategies of large models based on different corpora within them，and they may need to be treated differently. This result may provide experience and reference for further improving the regulation and guidance of science popularization by GenAI in the future.

This paper focuses on the synergistic developmental path between the scientificity and narrativity of science popularization. It systematically explains the mechanism for AIGC-driven synergistic optimization of scientificity and narrativity，analyzes the dual functions of AIGC in enhancing scientificity and optimizing communication，as well as the multidimensional issues behind its usage. Subsequently，it proposes corresponding optimization strategies for issues such as the detrimental effects of AI hallucinations on scientific rigor，the technical bottlenecks in generating highly complex scientific content，and the conflicts between instrumental rationality and value rationality. Namely，establishing multiple mechanisms to suppress AI hallucination generation，conduct narrative transformation for highly complex science popularization content，and build a synergy mechanism between instrumental rationality and value rationality.

Through a questionnaire survey of over 100 college students across the country，the current situation of science popularization reading among college students was preliminarily sorted out，and the main problems and corresponding countermeasures were analyzed. The results show that college students generally recognize the importance of science popularization reading，but their actual reading is insufficient，and they lack systematic reading plans. At present，the science popularization reading promotion activities for college students are faced with problems such as few brand projects，single activity forms，and a lack of innovation，which，to some extent，affect the effective implementation of science popularization reading for college students. Given these problems，it is suggested to strengthen ideological guidance，refine reading needs，and create a good campus reading atmosphere.

University museums play a unique role in science popularization education. The development of science popularization courses in these museums not only extends formal education but also serves as a vital channel for disseminating scientific knowledge. In the new era，it is essential to explore how university museums can effectively utilize their rich and distinctive collections for educational purposes. This study focuses on the University of Southern California Pacific Asia Museum as a case study to examine its practice and experience in developing science popularization courses based on constructivist theory. The findings reveal that the museum’s courses feature clear goals，diverse content，a varied teaching staff，and a robust evaluation system. The study proposes a four-dimensional approach to course development in university museums：setting clear course objectives，infusing distinctive content，ensuring adequate faculty support，and enhancing development through evaluation. This framework aims to provide guidance for developing science popularization courses in Chinese university museums and to support the effective implementation of science education activities in these institutions.

Based on the results of the National Civic Scientific Literacy Sampling Survey，this study reveals that the scientific literacy of Chinese youth（aged 18~35）exhibits three distinct characteristics：high-level，regional imbalance，and cognitive contradictions. The findings indicate that the proportion of youth with qualified scientific literacy significantly surpasses the national average. Notable disparities exist across regions：developed areas such as the Yangtze River Delta outperform western and rural regions. Highly educated and knowledge-intensive vocational youth form a clear advantage group. Scientific interests are predominantly concentrated in specific domains，with a heavy reliance on digital media and interactive scenarios for information acquisition. The field of artificial intelligence presents the characteristics of“high activity coinciding with anxiety coexisting”，reflecting the deep contradictions in digital transformation. To advance high-level technological self-reliance and further foster an innovation-driven nation，this study proposes the following recommendations：Guided by policy frameworks，strengthen the foundation for enhancing youth scientific literacy；Construct a layered and classified system for accurately improving the scientific literacy of young people；Build a youth science popularization ecosystem with collaborative participation of multiple stakeholders；Actively embrace artificial intelligence，with Guiding young people to grasp the technological dividends and ethical boundaries.

The effective communication of scientific information in popularization short videos requires the collaboration of multiple modal discourses. The integration，complementarity，and reinforcement among these multimodal discourses facilitate audiences’understanding of complex scientific knowledge. Based on a multimodal discourse analysis framework，this study explores the narrative strategies of science popularization short videos intending to enhance their effectiveness. This study selects thescience popularization short videos from the Bilibili account“Huazha Hua Xiaolao”as the research object，analyzing the interaction among visual，linguistic，and auditory modal discourses within the videos. Findings indicate that multimodal narratives enhance the narrative expressiveness of science popularization short videos，stimulate emotional expression，and expand cross-media storytelling capabilities. On this basis，this paper proposes the following narrative strategies：scene-based narrative contextual optimization，deep integration of emotions and narrative cues，and cross-platform multimodal storytelling with full-link dissemination. These strategies aim to provide theoretical and practical guidance for the creation and dissemination of science popularization short videos.

In the context of convergence media，the field of meteorological science popularization is showing a trend towards interactivity and visualisation. Through case analysis，it has been found that interactive visualisation in meteorological science popularization communication exhibits characteristics such as intertwined narrative structures，multi-dimensional interaction among narrative subjects，flexible shifts in narrative perspectives，and multi-modal narrative discourse. To promote interactive and visualised dissemination of meteorological science popularisation，a multi-subject collaborative meteorological communication interactive model can be constructed in the future. This model should include dialogue mechanisms involving policymakers（including venues），science popularization creators，and diverse audiences，innovative cross-media communication models for meteorological scientific achievements，and develop a technical platform for concrete meteorological science popularisation scenarios.

Xi Jinping Thought on the Rule of Law is the fundamental guideline and action guide for comprehensively advancing the rule of law. As an important component of comprehensively advancing the rule of law，the rule of law on science and technology popularization must adhere to Xi Jinping Thought on the Rule of Law as its fundamental guideline and action guide. Xi Jinping Thought on the Rule of Law guides the revised Law of the People’s Republic of China on Popularization of Science and Technology mainly in four aspects of logic，namely politics，value，theory，and practice. Regarding political logic，it upholds the comprehensive leadership of the Communist Party of China to ensure the socialist direction of the revised Law of the People’s Republic of China on Popularization of Science and Technology. In terms of value logic，it adheres to people-centered principles，insisting on the people-oriented nature of the revised Law of the People’s Republic of China on Popularization of Science and Technology. In terms of theoretical logic，it leads the localization research of the Law of the People’s Republic of China on Popularization of Science and Technology and promotes the optimization of the science and technology popularization legal system. In terms of practical logic，it guides the positive interaction between the reform of science and technology popularization and legal development，grasping the“key few”in the field of popularization of science and technology，and coordinating domestic and international rule of law on science and technology popularization.

The Law of the People’s Republic of China on Popularization of Science and Technology，promulgated in 2002，is an important milestone in the legal construction of science popularization in China，promoting historic achievements in science popularization. The new era of science popularization is confronted with new situations and challenges，which necessitate the revision and improvement of relevant policies and practices. This paper employs methods such as literature review，questionnaire surveys，and in-depth interviews. conducted a comprehensive evaluation of the implementation of the Law. The paper found that the Law has achieved remarkable results，fully realized the legislative objectives of serving the national strategy. The evaluation also found that the current problems such as the relevant provisions are not adapted to the high-quality development requirements of science popularization in the new era. The conclusions and recommendations of this evaluation study have been adopted and implemented in the revised Law of the People’s Republic of China on Popularization of Science and Technology in December 2024，which has condensed and solidified the good experience in the development of science popularization，and responded to the existing problems and new requirements of the development of China. On this basis，this study puts forward directional suggestions for further implementing the revised law from several aspects，like deepening the institutional arrangements of the two wings are equally important，achieving a higher level of socialized collaboration in science popularization，improving the supply of science popularization products and services，achieving a more solid basic support capacity for science popularization，and promoting the improvement of the policies and regulations on science popularization for industries and local governments.
