The new era of socialism with Chinese characteristics has put forward new requirements for science popularization. Popular science writers in the new era should not only popularize scientific knowledge, but also convey scientific worldview and methodology to the public. Both the scientific knowledge and humanistic awareness are essential to popular science writing. By mastering the basic rules of creative writing, popular science writers can integrate their own scientific and humanistic literacy and knowledge in their creation, so as to improve the quality of popular science works. Writing on the basis of domestic popular science creating and academic studies, writers need to learn from relevant experiences in the field of creative writing, and bring creative writing into the education system of popular science writers, which is helpful to form a new ecology of Chinese popular science writing.

Nowadays, popular science short videos have become an important carrier of science communication, as well as a focal point and important direction for deepening the content-production reform of science popularization. In this paper, we analyze the creation strategy of short science videos from three dimensions. Firstly, in terms of topic selection, producers can combine national development strategies and policy deployment, pay attention to national scientific and technological innovation achievements, refer to the annual guide for science popularization creation, draw on other large-scale science popularization activities and outstanding science popularization publications, combine current news and social hotspots and daily life, and explore suitable themes for creation. Secondly, as for the titles, one need to pay attention to the type of speech and the flexible use of a variety of sentence patterns and figures of speech, such as metaphors, parody and contrasts. Lastly, for better content presentation, technical advantages are brought into play to maximise the scientific, interesting and artistic nature of the work, enhance its appeal and public influence.

In the era of new media, the creators and disseminators of online popular science content should not blindly follow the trend, but learn to avoid legal risks and safeguard their own rights and interests. The article summarizes and analyzes the legal issues and risks faced by healthcare professionals in the creation and dissemination of live webcasts and short videos of popular medical science, and points out that the production of short videos of medical science should comply with regulations in both form and content, advocating that content creators need to have risk awareness. Finally, legal precautionary measures and ways to defend the rights of content creators are provided.

At present, the sales of children's science books in China continue to grow, and the proportion of original children's popular science books in this category has greatly increased. At the same time, the subjects of original children's popular science books vary from comprehensive encyclopedia to books of specific science discipline, from "grand narrative" to "small narrative". Many popular science works borrow the imaginative wings of literary writings, focus on children's interests, and value the readability, literariness, and narrative techniques of narratives, presenting readable and accessible narratives to children. In addition, the usage of animated 3D and AR images and adaptation of animation characters bring the books with stronger visual impacts and more playfulness.

Popular science short videos are usually vivid, intuitive and interesting. Compared with traditional media, short videos are more popular among the audience, as they are more in line with the market preferences and the preference of fragmented information of the Internet era, which has led to a change of methods in science popularization and an influx of content creators. Meanwhile, many problems have also arisen. For example, the number of creators is huge, but their content quality is uneven, and the low threshold of this field leads to a motley mixture of creators; many video creators emphasize on knowledge over value, resulting in the growing spread of rumors and pseudoscience amongst the rapid increase of video quantity; the platforms' algorithm fuels the production of "information cocoons", leading creators to create for web traffics and clicks; the lack of proper mechanism of evaluation as a guidance cause a scarcity of quality videos produced by scientists and technicians. Therefore, based on the current development of popular science short videos, the existing advantages, and emerging problems, this article proposes suggestions for the future development of popular science popularization short videos from the perspectives of the creation source, the evaluation mechanism of video quality and effect, and the integration of theory and practice in content creation.

The University of Science and Technology of China and Xinhuanet have jointly produced three micro films Always With the Original Intention, The Light of Science, The Moon Appears Brighter Over My Hometown, which have shaped the cinematic images of scientists of the older generation, respectively based on the lives of Guo Yonghuai, Yan Jici and Qian Linzhao. The three micro films used some pivotal props to blend the exemplary events of the protagonists into plots, and composed conflicts and struggles to shape characters, so as to present the honorable morals of patriotism and self-sacrificing of the scientists. However, the films simplify the relationships among the characters and fail to several non-fictional ones.

Science fiction is a genre of works combining the principles of science with the methods of literary creation, an integrating product of culture, science, technology, which also demonstrates the comprehensive strength of national science and technology. Based on the development of science fiction research in China, this paper draws a scientific knowledge map using CiteSpace for a visual analysis based on 1264 academic papers published in "CSSCI source journals" and "PKU core journals" from 2000 to 2020. The research sorts out the current research status and hot topics of Chinese science fiction studies in the past 20 years, summarizes the knowledge mapping and explores the future trends of Chinese science fiction research. The study finds that science fiction research has been increasingly flourishing from 2000 to 2020, covering the fields of literary texts, film and television industries, cultural theory, and technology and society. Research on sci-fi theories, relationships between science fiction and science popularization, promotions of sci-fi works, sci-fi industries, and grassroots science fiction fandom are the future trends of science fiction research, indicating that Chinese science fiction research has huge room for development.

Tales From The Loop, a science fiction TV drama, conveys the dual emotional tendencies of "depression" and "cure" through the circular and radial narrative structure. Its philosophy derives respectively from the emotional tearing triggered by the tragic conflict and the rational bridging guided by the spirit of tragedy. The science fiction narrative in the TV drama combines technology and emotion very well, which not only shows the human emotion under the influence of science and technology, but also highlights the disenchantment of technology through the power of emotion. The TV drama depicts the twists and turns of life through interactional observation, and enacts the elements of tragedy through the art form of science fiction. The audience could gain spiritual purification through the emotions of "fear" and "pity" displayed in the TV drama. The art form of sci-fi utopia can bring us unusual aesthetic experience.

The intellectuals of the late Qing Dynasty represented by Liang Qichao attached great importance to the communication advantages and social functions of fiction. As a combined product of literature and science, science fiction also naturally assumes the important mission of disseminating scientific knowledge and enlightening the public. However, when specific fictional texts are examined, the complicated understandings of science of the late Qing authors are revealed. It is discovered that many authors either held suspicious views of science, wrote stories against common sense, or believed in the philosophy of religion. These various attitudes, emotions and beliefs represent some common epistemological features during the process of science exploration, signifying progressive values in modern Chinese thought.

With the development of mobile Internet technology, new media has become the main means of obtaining information, socializing and entertainment. New media has become important platforms for the creation of popular science content due to its low threshold of content production, speedy transmission, and strong interaction, which has brought great changes to the presentation of popular science content. This paper analyzes the new characteristics of popular science content creation in the era of new media, and the problems in popular science creation, including severe homogeneity, insufficient scientific reliability and inferior business models. In response to these problems, this paper proposes strategies for the creation and its communication of new media popular science.
