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.

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.

Video has become an important form of media communication, and popular science communication has also dropped its old-time solemnity through short videos. By selecting typical cases of popular science short videos on Bilibili.com, this paper analyzes the basic features, presentation forms and dissemination effects of popular science short videos, explores the creation features and dissemination laws of the most-viewed popular science short videos, and explains the filling and reconstruction of "knowledge gap" brought by these popular science short videos on Bilibili.com, revealing a new interactive relationship between communicators and receivers.

In the science fiction of late Qing dynasty, the scientific and technological achievements invented by experts and specialists were weaved into the narration in the form of imaginary "things", and became the material cornerstone for novelists to construct the fictional space. In the functional imagination of this "things", the literariness of Late Qing science fiction was weakened by the authors' exaggeration of the performance of "thing", repetition of political theme of "science saving China", and their overt concern of society. Despite of these, the spirit of embracing science and exploring the unknown in these fictional texts still has considerable artistic values.

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.

This article focuses on the science fiction published in the journal Kexue Wenyi/QiTan (Kexue Wenyi renamed as QiTan in 1989) from 1984 to 1990, revisiting the mid-to-late 1980s, a nadir in the history of Chinese science fiction that has long been neglected by the academics, and identifying the symptoms of the times in the science fiction of the period of societal transformation. Compared to the beginning of "the New Era", science fiction in the mid to late 1980s reflected a lot of social problems that emerged in a more advanced stage of modernization, as well as the ensuing confusion and reflections. It has developed significantly in terms of subject range and ideological tension, providing us with a new perspective on China's unique and tortuous modernization process since "the New Era".

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.

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.

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.

In the times of crisis, editors tend to face a task of emergent editing and publishing, but they still need to dig deep into the demand of book market, and to publish some popular books to cater to the publics' attention to the emergency event. The article is about a book of COVID-19 prevention, also a "Best Book on China". Content selection of the book was changed from the development of COVID-19 pandemic to public immunity enhancement, and the creation concept was changed from "giving people fish" to "teaching people fishing", which shows that the creating and editing team of the book adheres to the guiding spirit of scientific reliability, inspiration, and practicability. The good market acceptance and social recognition all proved that a successful health popular science book editing team should take advantage of the social trend, think ahead of the times, and have a healthy cooperation between the author and the editor.
