Since the turn of the 21st century，the imagination of alternative history in Chinese science fiction has been grounded in technological imagination，continually re-examining the enlightenment ideals of democracy and science while exploring a distinctly Chinese sci-fi aesthetic. This is reflected in three aspects: first，the construction of a holistic，cyclic，and unified Eastern philosophy of technology，highlighting the poetic beauty of traditional Chinese craftsmanship; second，the infusion of characters with the Confucian concept of“Yi”，representing righteousness and humanitarian concern，promoting the Chinese ethical spirit of upholding righteousness and embracing innovation; third，the carnivalization of science fiction“New Tales”，filled with wit，humor，and ironic aesthetics，which display postmodern cultural features such as the retreat from historicity and the fragmentation of subjectivity. These explorations demonstrate writers’aspirations to transcend the epistemological framework and cultural aesthetics of Western modernity，to explore and elevate traditional Chinese humanism and rational thought on science and technology，while also capturing the characteristics of postmodernism and expressing concerns for contemporary realities.

Based on the principle of spatialization of time，Haiya’s The The Space-Time Painter imagines the time travel realized by space projection，thereby unfolding a spatio-temporal narrative where the Northern Song Dynasty overlaps with the present. The historical perspective implied in The Space-Time Painter aligns with the propositions of neo-historicism，and the imaginative portrayal of historical time and space reinvigorates the narrative resources of national identity in historical science fiction. The internal conflict between rational disenchantment and historical myths highlights the tensions surrounding national identity in Chinese historical science fiction.

In 2023，the overall development of long-form science fiction novels has been promising，maintaining a high standard of creativity，producing numerous outstanding works，and exhibiting new trends. These are mainly reflected in five aspects: first，the popularity of the “Metaverse” theme remains strong，with high-quality works showcasing localized creative features; second，the theme of artificial intelligence has become a new growth point，producing major works rarely seen in recent years; third，an increasing number of works focus on China’s cutting-edge technological development，reflecting cultural confidence；fourth，there is a rising trend of cross-media writing，with the film and television styles of works becoming increasingly prominent；fifth，an increase in philosophical reflection adds depth to the narratives. With the rapid advancement of Chinese technology and a society increasingly immersed in technological progress，the public’s imagination of the future world，along with the creation of science fiction，has raised the bar for the genre. Writers must guard against low-level repetition，avoid clichéd patterns，and strive to forge a path for science fiction literature and art with distinct Chinese characteristics.

Contemporary popular science works exhibit diverse narrative forms，marked by the emergence of new paradigms such as“popularizing scientific writing”and“infusing everyday life with scientific concepts”. Firstly，these new approaches enhance public participation and trust in science，mitigating prejudices within the scientific community and promoting the democratization and popularization of scientific knowledge. Secondly，they render abstract scientific concepts concrete and practical. Finally，they provide psychological support to those facing similar challenges and cultivate a sense of mutual aid. By enhancing the vividness and approachability of popular science writing，these new paradigms effectively promote the dissemination and utilization of scientific knowledge，thereby holding significant social and practical value.

Western science fiction films serve as a battleground for competing discourses on the posthuman body. The imagination of the posthuman body reflects the philosophical debates surrounding the essence of human being in the technological context. Within these debates，transhumanism，extending the humanist tradition，envisions posthuman cyborgs as embodiments of a liberated subjectivity，seeking to enhance human agency and will through technology. Moreover，critical posthumanism advocates for a decentralized culture that challenges anthropocentric views of the body. Therefore，the body narratives in Western posthuman science fiction films portray both the utopian vision of a technologically enhanced future，where technology merges with organic life，and the dystopian fear of the loss of Enlightenment humanism，as manifested in grotesque and uncontrollable body images resulting from technological corruption. Meanwhile，the plasticity of posthuman bodies challenges the essentialist assumptions of human identity，thereby deconstructing traditional biopolitical categories such as gender and race.

In the context of new media science communication，scientists，while holding positions of authority and being key contributors to high-quality popular science content，also face challenges in both creation and dissemination. This paper uses the case of Dr. Wang Liming，a scientist in the life sciences，to explore strategies for scientists' participation in popular science communication within new media environments. It examines how scientists can balance their professional roles with their responsibilities as science communicators，and how they can effectively select topics and develop communication strategies. The study suggests that scientists collaborate with professional science communicators，while recognizing their social responsibility in public communication. When creating content，scientists should align their topics with contemporary societal needs and anxieties，use a conversational tone，and emphasize the historical development of science. In communication，Dr. Wang’s use of personal science communication branding demonstrates how to construct an effective communication matrix，transition popular science content between books and online knowledge platforms，leverage key events to enhance brand influence，and prioritize audience feedback and interaction. The paper concludes that in the new media era，scientists need to update their science communication concepts，explore suitable creation and dissemination models，and strengthen their skills in producing and sharing popular science content.

Popular science documentaries are an important subtype of science documentaries. With the advancement of media technologies and the increasing integration of aesthetics into daily life，combining popular science documentaries with desktop cinema and expanding the content themes of desktop films has marked a milestone in the integration of science and visual media. Network Neighborhood exemplifies this new form of media art by using visual symbols to narrate a popular science journey within computer desktops，presenting diverse artistic symbols and showcasing scientific symbolic landscapes through smart replicated images.
