 Infectious diseases caused by various virulent mosquito-borne viruses have been a major global public health challenge, but there is still a lack of safe and effective prevention and control measures. In the virus transmission cycle, after mosquitoes acquire the virus through blood-feeding, the virus sequentially infects their intestinal cells, hemocoel, and salivary glands, ultimately conferring virus transmission capability to the mosquitoes. Notably, the mosquito gut, as a key tissue determining viral susceptibility, has its microbial community significantly influenced by the living environment. This results in mosquitoes from different habitats exhibiting varying vector competence due to differences in their gut microbiota. Our team, in collaboration with partners, isolated a bacterium named Rosenbergiella_YN46 with significant antiviral activity from the gut of wild Aedes albopictus in Yunnan. This bacterium induces acidification of the intestinal lumen by secreting glucose dehydrogenase, thereby effectively inhibiting infections by dengue virus and Zika virus. Epidemiological surveys indicate that Rosenbergiella_YN46 is commonly present in mosquito populations in low-endemic dengue areas, but relatively rare in high-endemic dengue areas. Semi-field environmental intervention experiments have confirmed that this bacterium can significantly reduce the viral susceptibility of mosquitoes. This discovery provides a new environmentally friendly biological control strategy for the prevention and control of mosquito-borne infectious diseases such as dengue fever.

 Humanoid robots exhibit strong adaptability in complex environments due to their human-like structure and behavior patterns. However, limited by the current level of autonomous intelligence, they still struggle to complete operations independently in high-risk and high-complexity tasks. As a critical complement, dual-arm teleoperation technology introduces human intention and judgment into the control loop, enabling precise manipulation of the robot's arms and serving as an important pathway to practical deployment. This paper systematically reviews the development of humanoid robots and their key technologies in perception, cognition, and control. It focuses on recent advances and representative applications of dual-arm teleoperation in areas such as human-robot mapping, multimodal feedback, and master-slave control. Finally, the paper discusses the challenges and future directions of dual-arm teleoperation, aiming to provide insights for further research and engineering applications.

 Sporopollenin is a biopolymer considered as one of the most stable organic substances on the Earth. As a principal component of the outer walls of terrestrial plant spores and pollen, sporopollenin plays a pivotal role in the evolutionary transition of plants from aquatic to terrestrial environments. Its unique chemical stability enhances the resistance of pollen and sporewalls, thereby assisting plants in adapting to various terrestrial stresses such as high temperature, drought, and ultraviolet radiation. Despite its crucial protective role in plant reproduction, the high stability of sporopollenin has long posed significant challenges for elucidating its chemical composition. However, through a series of structural, chemical, and genetic experiments, researchers have made substantial progress in revealing the molecular structure and biosynthesis mechanisms of this biopolymer. Scientists have utilized gene localization techniques to decipher the pathways involved in sporopollenin biosynthesis, including fatty acid pathways, phenylpropanoid pathways, and flavonoid pathways, which exhibit considerable conservation among terrestrial plants. Recent analyses combining chemical dissolution methods with nuclear magnetic resonance and mass spectrometry have resolved the core structure of sporopollenin. Phenylpropanoid derivatives form polymers through carbon-carbon bond cross-coupling, while hydroxylated fatty acids crosslink these polymers to constitute the core structure of sporopollenin. These new findings not only provide a foundation for understanding the reproductive mechanisms of how plants cope with stress in terrestrial environments but also open up new avenues for utilizing this abundant and highly stable biological material

Flowers of angiosperms attract pollinators such as insects to transfer pollen to the stigmas of conspecific individuals, thereby ensuring reproductive success. In this mutualistic relationship, pollinators provide pollination services, while plants offer rewards such as nectar. This relationship has driven the coevolution of floral traits—including color, morphology, scent, nectar, and other traits—and pollinator preferences. Different pollinators exhibit specific preferences for these traits, and the suite of floral characteristics adapted to particular pollinators is collectively referred to as the pollination syndrome.When environmental conditions change or pollinators change, plants may undergo pollinator shifts to adapt to new pollinators. Evidence from multiple plant families and genera suggests that such shifts not only drive innovations in floral traits but also promote population divergence through pollinator-mediated reproductive isolation, ultimately serving as a key mechanism for rapid species radiation in angiosperms. However, the molecular mechanisms by which pollinator shifts drive speciation remain unclear. Advances in genomics and molecular genetics have accelerated the identification of key genes, enhancing our understanding of pollinator-mediated reproductive isolation. In this review, we first introduce the concepts of pollination syndromes and pollinator shifts, then highlight recent progress in elucidating the molecular mechanisms underlying the transition of pollination syndromes. Finally, we discuss the interactions between pollinator-mediated reproductive isolation and other isolation mechanisms, as well as their implications for the process of speciation.

Silicon quantum dots (SiQDs), as emerging nanoscale semiconductor materials, have attracted extensive attentions in optoelectronic devices and light-emitting diodes (LEDs) due to their excellent photoluminescence and electrolumine scence properties, low toxicity, environmental friendliness, and good compatibility with silicon-based microelectronics fabrication processes. Compared with conventional III-V semiconductor quantum dots, the luminescence characteristics of SiQDs can be tuned and optimized via size control, surface passivation, and doping, demonstrating great potential in various applications. In recent years, researchers have conducted in-depth investigations into the luminescence mechanisms of SiQDs by combining experimental and theoretical approaches. These mechanisms include quantum confinement effects, defect-induced emission, and the influence of surface ligands. Significant breakthroughs have been achieved in enhancing quantum yield and improving emission stability. However, further optimization of the optoelectronic properties of SiQDs and their integration into practical devices remain key challenges. This paper reviews the main synthesis methods, optoelectronic properties, and recent application advances of SiQDs, analyzes critical issues encountered during their development, and discusses possible future research directions.

 The interaction between plant pathogenic fungi and mycoviruses plays a significant role in ecosystems. Weakly virulent mycoviruses can significantly reduce the virulence and infectivity of plant pathogenic fungi. In some cases, fungal pathogens can even transform into beneficial endophytic fungi after viral infection. As a result, using weakly virulent mycoviruses as biocontrol agents become an emerging and promising strategy for controlling plant fungal diseases. In recent years, with the rapid development of environmental sampling and molecular biology techniques, research on mycoviruses has made significant progress, especially regarding the complex interactions among viruses, fungi, and plants. This review provides a comprehensive analysis of the research progress on plant-fungus-virus interactions and looks forward to the potential applications of this field in plant disease management.
