The producer of knowledge becomes the disseminator of knowledge, and the young scientific researchers become the bloggers of popular science. This is a new era story of spreading scientific knowledge, guiding the whole people to learn, and improving the scientific and cultural literacy of the whole people in the information society. Chen Liang, the blogger of "online popular biometrics" with more than 20 million fans, "Ethan thinks soberly", the blogger of popular science in psychology, Wen Yifei, the blogger of popular science in finance and economics with more than 10 million fans, and so on. On the popular communication platforms such as Station B, Tiao Yin, microblog, and Xiaohongshu, obscure scientific knowledge is made clear through humorous language and vivid examples. These popular science communication practices fit in with the theme of knowledge communication competition, knowledge boundlessness and knowledge utility maximization in today's era. Young scientific research workers lead in the fierce "knowledge dissemination competition". The progress of communication technology has enriched media forms. The rise of We Media has expanded the main body of communication, broadened the communication channels and reshaped the communication environment. However, the Internet environment is full of inaccurate, invalid and false information, making Internet users vulnerable to the impact of "information cocoon room" and "information overload". In this case, we need scientific and systematic knowledge production and simple knowledge expression, occupy the highland of knowledge communication competition in the new media era, and export scientific and universal knowledge for the society. Young scientific research workers become popular science bloggers. They not only master systematic scientific knowledge in their respective fields, but also are creative and imaginative. They are good at finding the combination of professionalism and popularity in scientific knowledge, and show their skills on various network platforms. They are favored and pursued by Internet users. Young scientific research workers practice "knowledge without boundaries" with "public science popularization". Scientific knowledge is the spiritual wealth accumulated over time and shared by the society. Although there is a cognitive threshold for systematic and in-depth scientific knowledge, knowledge learning should not delimit identity boundaries. Internet technology has greatly reduced the cost of knowledge dissemination, and advocating "knowledge without boundaries" should be the value concept of the information age. Young scientific research workers devote themselves to public science popularization, spread professional scientific knowledge through the network platform, and established a shared knowledge oasis in the entertainment atmosphere to promote the popularization and borderless reception of scientific knowledge. At a time when Internet paid knowledge products are popular, public science popularization is a return to the public attribute of scientific knowledge. Young scientific research workers bravely shoulder the task of improving national scientific literacy and cognitive level. Scientific knowledge can be produced in order to explain the relationship between nature and society, and its maximum utility value can only be brought into play when it flows smoothly in the society. Young scientific research workers are mainly engaged in the production of knowledge in universities or scientific research institutions, and knowledge dissemination is mostly confined to scientists. Only when young scientific research workers become "bloggers" of popular science, break down the wall of knowledge flow, let the masses of people access and receive this knowledge, and promote the improvement of national scientific and cultural literacy and public awareness, can the utility of knowledge be maximized. In the process of science popularization, young researchers are good at using the Internet platform to improve the convenience of knowledge dissemination, which greatly increases the audience of scientific knowledge and reduces the marginal cost of knowledge utility. The Internet era has provided new opportunities for science popularization innovation, and the development of new media has widened the channels for knowledge dissemination. In this context
