In a remarkable fusion of public engagement and space science, China has officially named four pioneering mice that recently completed an orbital mission aboard the nation’s space station. The Chinese Academy of Sciences revealed the selected names—Wangtian (gaze at the sky), Lanyue (reach for the moon), Zhuiyun (chase the clouds), and Zhumeng (follow the dream)—during a special public science event on Saturday.

The naming initiative formed part of an innovative public outreach campaign orchestrated by Xinhua News Agency, which invited citizens to propose and vote on names for the rodent astronauts. The four selected mice, originally identified as numbers 6, 98, 154, and 186, were chosen from a pool of 48 candidates for their historic space voyage.

Launched aboard the Shenzhou XXI crewed spacecraft on October 31, the mice spent approximately two weeks in microgravity conditions before returning safely to Earth with the Shenzhou XX crew on November 14. The mission represents China’s continuing advancement in space biological research, particularly in understanding how space environments affect mammalian physiology.

Dr. Li Tianda, an expert at the Institute of Zoology of the Chinese Academy of Sciences, explained the scientific significance: ‘We have initiated comprehensive studies on these mice following their return to Earth. Our research aims to uncover how the space environment affects mammalian physiology and behavior, with particular focus on stress response mechanisms and adaptation processes.’

To celebrate this achievement and engage the public further, a special month-long ‘Flying Mice’ exhibition has been inaugurated at the National Zoological Museum of China. The event, jointly organized by the Technology and Engineering Center for Space Utilization and the Institute of Zoology, features detailed information about the mission, cartoon illustrations of the named mice, and insights into the cutting-edge biological experiments being conducted as part of China’s space program.

A breathtaking astronomical event captivated observers across Japan as a brilliantly luminous meteor streaked across the night sky, creating a stunning visual display against the iconic silhouette of Mount Fuji. The extraordinary phenomenon, captured by numerous eyewitnesses and surveillance systems, occurred during optimal nighttime viewing conditions, transforming the region into a temporary theater for celestial observation.

According to astronomical experts, this particular meteor belongs to the category of exceptionally bright fireballs, characterized by its intense luminosity and prolonged visibility. The spectacular display lasted several seconds as the space rock descended through Earth’s atmosphere, undergoing rapid disintegration while generating tremendous heat and light through atmospheric compression.

Japan’s geographical position and typically clear atmospheric conditions make such sightings relatively frequent compared to other regions, though the proximity to the nation’s most recognizable natural landmark created particularly dramatic viewing circumstances. The meteor’s trajectory appeared to originate from the asteroid belt between Mars and Jupiter, though precise orbital calculations remain ongoing by scientific organizations.

The event has generated significant interest within the scientific community, with researchers emphasizing the importance of such occurrences for studying the composition of interplanetary material. Simultaneously, the visual documentation provides valuable data for refining meteor trajectory prediction models and understanding atmospheric entry dynamics of extraterrestrial objects.

In a landmark achievement for Indian genetic research, the nation’s inaugural gene-edited sheep has successfully reached its first year of development. The animal, named Tarmeem (Arabic for ‘modification’), was born on December 16, 2024, at Sher-e-Kashmir Agricultural University in Srinagar, Indian-administered Kashmir, where it resides under controlled conditions alongside its non-edited twin sister.

The research team employed CRISPR-Cas9 technology—a revolutionary gene-editing system—to precisely modify the myostatin gene, which naturally limits muscle development in mammals. Dr. Suhail Magray, a key researcher on the project, explained the process: ‘We extracted embryos from pregnant sheep and performed targeted gene editing before transferring them to foster recipients. After 150 days of gestation, the edited lambs were born.’

Professor Riaz Shah, dean of veterinary sciences and principal investigator, reported that Tarmeem demonstrates normal physiological development with a notable 10% increase in muscle mass compared to its non-edited twin. ‘We anticipate further muscle development as the animal matures,’ Shah noted, adding that the team has implemented rigorous monitoring protocols to evaluate long-term health outcomes.

This breakthrough culminates seven years of dedicated research by an eight-member team that initially faced significant challenges. The researchers attempted multiple strategies before achieving success in December 2024, with only one successful gene-editing outcome from five live births following seven IVF procedures.

The scientific community highlights the potential agricultural implications of this advancement. Professor Nazir Ahmad Ganai, the university’s vice-chancellor, emphasized that gene-editing could address Kashmir’s substantial mutton deficit—the region consumes approximately 60,000 tonnes annually while producing only half that amount. ‘By increasing body weight by up to 30%, this technology could enable more efficient meat production with fewer animals,’ Ganai explained.

While CRISPR technology—co-developed by Nobel laureates Emmanuelle Charpentier and Jennifer Doudna—has revolutionized medical research globally, its application in agriculture remains subject to regulatory scrutiny. The Indian research team has submitted proposals for government funding and approval to scale this technology for broader agricultural implementation.

Globally, nations including Argentina, Australia, Brazil, Japan, and the United States have already incorporated gene-edited animals and crops into their agricultural systems. The United Kingdom is poised to permit gene-edited foods beginning next year, while the European Union recently moved to reduce regulatory barriers for such products.

Despite ethical debates surrounding genetic modification, scientists distinguish between gene editing (modifying existing genes) and genetic modification (introducing foreign genes). As India evaluates whether to classify Tarmeem as a natural genetic variant, researchers remain optimistic about CRISPR’s potential to transform sustainable food production nationwide.

In a groundbreaking ecological development, Northeast China Tiger and Leopard National Park has documented unprecedented footage of a wild Amur tigress successfully raising five cubs. The remarkable video, captured via camera trap in November 2025 within the Hunchun sector of the world’s largest tiger reserve, was formally announced by World Wildlife Fund China this week.

According to WWF China’s analysis, the adult female tiger is approximately nine years old, while her five offspring are estimated to be between six and eight months old. This exceptional case represents a significant deviation from normal reproductive patterns, as wild Amur tigers typically produce litters of one to four cubs even under optimal environmental conditions.

The conservation organization emphasized the extraordinary nature of this discovery, noting that the survival of all five cubs in a region with still-recovering prey populations indicates substantial ecological improvement. Simultaneously, rangers documented another Amur tigress, aged five to eight years, successfully nurturing four cubs of similar age in the same protected zone.

As apex predators, Amur tigers serve as critical indicators of ecosystem health, reflecting both habitat integrity and food chain stability. The consistent observations of multiple tiger families with high cub survival rates demonstrate the effectiveness of comprehensive conservation strategies implemented in the region. These measures include enhanced habitat protection, intensified anti-poaching patrols, and sophisticated human-wildlife conflict management protocols.

Commonly known as Siberian tigers, Amur tigers predominantly inhabit Russia’s Far East and Northeast China. Classified among the world’s most endangered species, they function as flagship indicators for forest ecosystem vitality. From a precarious population of just 12-16 wild individuals in China during 1998, current estimates indicate approximately 70 Amur tigers now roam within the Northeast China Tiger and Leopard National Park, signaling a remarkable conservation recovery.

NANJING—A groundbreaking scientific forum convened this month at Nanjing University has revealed the extensive impact of vehicular traffic on urban wildlife populations across China. The Forum on Road Safety and Wildlife Conservation, held December 14 at the university’s Xianlin campus, brought together over 60 representatives from 19 academic institutions and environmental organizations to address the growing crisis of wildlife-vehicle collisions.

The gathering marked the culmination of pioneering research led by Professor Li Zhongqiu of Nanjing University’s School of Life Sciences, whose work has catalyzed China’s first systematic study of urban roadkill. The research initiative began unexpectedly in 2020 when Professor Li witnessed the tragic death of a Siberian weasel near campus—an event that exposed the widespread yet undocumented phenomenon of wildlife fatalities on urban roadways.

Recognizing the critical data gap, Professor Li’s team launched a comprehensive survey in 2021 that has since evolved into a nationwide citizen science project. Through a specially designed WeChat mini-program, the initiative has collected more than 8,000 verified roadkill reports from over 2,000 contributors across China, providing unprecedented insights into urban biodiversity impacts.

Scientific analysis of this data enables researchers to monitor population trends, identify vulnerable species, and develop targeted conservation strategies. The research highlights the urgent need for infrastructure adaptations including wildlife crossings, specialized fencing, and habitat corridors to reduce animal-vehicle collisions.

The forum participants emphasized that roadkill data serves as both an ecological indicator and a policy tool, providing evidence-based recommendations for urban planning and transportation design. This collaborative approach between academic institutions and public participants represents a innovative model for environmental research in densely populated regions.

Scientists have made a significant entomological discovery within the ancient wooden structures of Tibet’s Potala Palace, identifying a previously unknown genus and species of beetle. The finding, detailed in an international zoological taxonomy journal, represents a major advancement in Coleoptera research with important implications for cultural heritage preservation.

The insect, named Lhasella potala, measures between 4.8 to 6.9 millimeters and exhibits a distinctive reddish-brown coloration. Research team member Zhou Xuan, a PhD student, confirmed the species’ unique taxonomic status through comprehensive morphological analysis, anatomical examination, and DNA barcoding techniques.

This discovery has revealed potential conservation challenges, as the beetle’s wood-boring larvae may pose structural risks to the UNESCO World Heritage site. Subsequent investigations have detected the species in multiple historical locations throughout Lhasa, indicating a broader distribution than initially presumed.

Kunga Tashi, deputy director of the Potala Palace Management Office, emphasized the critical importance of integrating ecological research with cultural conservation methodologies. This interdisciplinary approach aims to simultaneously protect both biodiversity and invaluable heritage structures.

The research collaboration brought together experts from Peking University, the Xizang Plateau Institute of Biology, and the Potala Palace Management Office. Scientists now plan to conduct further studies on the beetle’s biology and behavior to develop more effective management strategies for historical preservation sites across the region.

Fifteen distinguished geoscientists have received China’s most prestigious geological honor, the Li Siguang Geological Science Award, in a ceremony held recently in Beijing. The awards recognize exceptional contributions to both field research and technological advancements within the geological sciences.

The 19th edition of this biennial award distinguished eight recipients with the Field Work Award and seven scholars with the Research Award. The ceremony highlighted the critical role of geological work in China’s current development phase, particularly in ensuring national energy security and achieving scientific self-reliance.

Natural Resources Minister Guan Zhiou congratulated the awardees and emphasized the evolving nature of modern geology. “Contemporary geology has transformed beyond a singular discipline into an integrated field combining artificial intelligence, big data, and advanced manufacturing technologies,” Minister Guan stated. He particularly stressed the importance of challenging conventional theories in deep-earth exploration projects to foster groundbreaking discoveries.

The minister called upon geological professionals to embody the patriotic spirit and innovative mindset of Li Siguang, the renowned Chinese geologist commemorated by this award. He described innovation as “the primary driving force” advancing geological endeavors.

Among the honorees, Chinese Academy of Sciences academician Dai Shifeng expressed gratitude for the national research system’s support and the foundational work of previous generations. Professor Dai committed to pursuing more systematic research on metallogenic mechanisms of key minerals within coal series and their practical applications. He also emphasized mentoring young scientific talent to ensure the continuation of Li Siguang’s legacy among new generations of geologists.

Established to honor the scientific spirit of Li Siguang, this prestigious award serves as both recognition of exceptional achievement and inspiration for continued innovation in China’s geological community.

Professor Li Chuanyou, a distinguished plant molecular biologist from Shandong Agricultural University, has been honored with the prestigious Humboldt Research Award in recognition of his lifetime contributions to understanding plant defense and regeneration mechanisms. The award celebrates his four decades of pioneering research that has fundamentally changed our understanding of how plants communicate, defend against threats, and repair damage.

Growing up in China’s agricultural heartland of Shandong province, Li developed an early fascination with plant growth that would shape his entire career. After obtaining his master’s degree in crop genetics and breeding from Shandong Agricultural University in 1994, he began his academic journey as both teacher and researcher at the same institution.

Li’s most significant breakthrough came during his postdoctoral research at Michigan State University (1999-2003), where he challenged existing scientific consensus about plant defense signaling. While scientists had believed since the 1970s that a substance called systemin served as the primary alarm signal when plants were injured, Li demonstrated that jasmonic acid actually functioned as the long-distance mobile alarm signal, with systemin acting merely as an ‘alarm amplifier’ at the injury site.

This discovery, hailed by the journal Science in 2002 as a major breakthrough in plant and microbe signal transduction, represented just the beginning of Li’s contributions. He subsequently led a decade-long investigation into how plants achieve tissue regeneration without the ability to escape harm. Through meticulous examination of tens of thousands of mutant tomato variants, his team identified a key gene capable of activating stem cells to facilitate damaged tissue regrowth—findings published in the journal Cell last year.

Beyond his fundamental research, Li has spearheaded international collaborative efforts, working with over 300 scientists from 14 countries to sequence the complete genome of both cultivated tomatoes and their wild ancestors. This genomic mapping has provided crucial insights controlling plant growth, ripening, flavor, and firmness while enabling the development of disease-resistant varieties.

As dean of the College of Life Sciences, Li has translated his research into practical applications, developing more than 30 high-end tomato varieties that offer domestic alternatives to imported seeds. Through the Taishan Academy of Tomato Innovation—established in 2023 through a partnership between Shandong Agricultural University and Tai’an city—Li’s team continues to bridge fundamental research with molecular breeding and variety promotion.

Throughout his career, Li has maintained that research must ultimately ‘return to the land,’ serving farmers and bringing better food to people—a philosophy that has guided his work from laboratory discoveries to tangible agricultural improvements.

China’s fleet of three advanced manned submersibles has achieved a remarkable milestone by completing 1,746 deep-ocean dives, according to the Institute of Deep-sea Science and Engineering at the Chinese Academy of Sciences. The announcement made Wednesday in Sanya, Hainan Province, highlights the growing capabilities of China’s deep-sea exploration program.

The three vessels—Fendouzhe (Striver), Shenhai Yongshi (Deep Sea Warrior), and Jiaolong—are projected to complete 314 dives during 2025 alone, demonstrating accelerated activity in underwater research. Each submersible has contributed unique achievements to marine science this year.

Fendouzhe made history by conducting China’s inaugural manned scientific expedition beneath the ice-covered regions of the Arctic Ocean. The same vessel also facilitated an international collaborative mission to New Zealand’s Puysegur Trench, located off the southwestern coast of South Island, marking significant progress in global oceanographic cooperation.

Meanwhile, Shenhai Yongshi has pioneered archaeological exploration in the deep sea, completing 18 dives along the northwest continental slope of the South China Sea. The submersible operated in coordination with unmanned underwater vehicles, leading to groundbreaking discoveries in deep-sea archaeology that reshape our understanding of maritime history.

The cumulative achievements of these deep-sea vehicles represent China’s growing sophistication in underwater technology and oceanographic research, contributing valuable data to the global scientific community while pushing the boundaries of deep-sea exploration capabilities.

Groundbreaking archaeological research has fundamentally reshaped our understanding of human habitation on the Qinghai-Tibet Plateau, with new evidence pushing the timeline of human activity back to approximately 100,000 years ago. This revelation emerged from comprehensive findings presented by the Xizang Autonomous Region’s cultural heritage authorities during a recent press briefing in Lhasa.

The discoveries form part of the ongoing national ‘Archaeological China’ initiative, which has conducted extensive fieldwork across the region since 2021. Archaeologists have executed 42 systematic excavations spanning 19 distinct locations, covering approximately 8,100 square meters of investigation. This methodological approach has enabled researchers to construct a continuous chronological narrative of human occupation across diverse geographical areas.

The archaeological record now demonstrates eight significant Paleolithic sites, four Neolithic locations, six early metal age sites with burial complexes, and one major Tubo period settlement. Particularly noteworthy is the emergence of advanced blade technology in northern Xizang approximately 40,000 years ago, followed by the proliferation of microlithic tools around 10,000 years ago.

Cultural development milestones indicate the region’s transition to Neolithic practices around 5,000 years ago, with copper implements appearing roughly 3,800 years ago and iron technology developing about 2,800 years ago. The rise of the Tubo Kingdom around 1,400 years ago represents the region’s entry into documented historical periods.

Concurrently, Xizang has completed its fourth national cultural relics survey, revealing unprecedented growth in archaeological site identification. By May 31, researchers had re-examined over 4,200 previously recorded sites while adding 3,346 newly discovered locations. This brings the region’s total documented cultural heritage sites to 7,623, with particularly significant concentrations in Shigatse, Lhokha, and Ngari prefecture—each contributing over 500 new sites.

According to Xu Shaoguo, deputy director of the regional cultural heritage bureau, Xizang now ranks among China’s most rapidly expanding regions for archaeological discovery while maintaining exceptionally low rates of cultural relic loss. The comprehensive survey has yielded new findings across all county-level administrative units, demonstrating the region’s extraordinary archaeological richness and preservation.
