  3D Uterine Embryo Implantation Simulating Chip Cracks the Code of Repeated Implantation Failure

  A single chip brings new hope for precise treatment to infertility patients. A research team led by Researcher YU Leqian from the Institute of Zoology of the Chinese Academy of Sciences, in collaboration with scientists from worldwide, has successfully developed a 3D uterine embryo implantation simulating chip. For the first time, the entire process of human embryo implantation has been completely replicated in the laboratory. This research breaks through the long-standing ethical and technical bottlenecks in the field, providing a novel research platform for gaining deeper insights into the mechanisms of maternal-fetal crosstalk and elucidating the pathological basis of Repeated Implantation Failure (RIF), thereby offering a dawn of precise treatment for patients. The related research findings were published in the journal Cell.

  Researchers Uncover Key Gene Linking Mosquito Metabolism and Reproduction

  Mosquito-borne diseases such as dengue, Zika, and yellow fever continue to pose a significant global health threat, infecting millions of people each year. However, current control efforts are increasingly challenged by the rise in insecticide resistance and the limited availability of effective vaccines. Understanding the molecular mechanisms underlying mosquito reproduction is therefore essential for developing new and sustainable strategies to control mosquito populations and reduce disease transmission.

  New Study Reveals Hybridization Enhances Montane Birds Adaptation to Climate Change

  Climate change is driving drastic environmental shifts and accelerating global biodiversity loss. Hybrid introgression has recently been recognized as an important mechanism facilitating rapid adaptation to historic climate change. However, empirical evidence remains lacking as to whether introgression can enhance future climate resilience, particularly for narrow-ranged species inhabiting mountainous regions that serve as biodiversity hotspots.

  Researchers Reveal Complex Sequence Basis for Adaptive Convergent Evolution of Protein Functions by Deep Learning

  Convergent evolution refers to the independent emergence of similar shape and functions in different lineages of species, such as the wings of birds and bats. Recently, a research team led by Dr. ZOU Zhengting from the Institute of Zoology, Chinese Academy of Sciences proposed a novel approach based on cutting-edge deep learning methods to investigate the complex molecular basis of such phenomenon. The study was published on Sep 23 in PNAS.

  Integrating Population Genomics and Environmental Data to Predict Adaptation to Climate Change in Post-bottleneck Tibetan Macaques

  The results show that the Tibetan macaque is divided into two genetic groups: eastern China (including the Huangshan population in Anhui, the Wuyishan population in Fujian, and the Mangshan population in Hunan) and western China (including the Sichuan population, the Wumengshan population in Yunnan, and the Fanjing Mountain population in Guizhou).

  Nature | Decoding and Manipulating the Biosynthesis of Locust Aggregation Pheromone

  The research team first determined that the synthetic substrate of 4VA is derived from plant phenylalanine. Subsequently, using KEGG combined with the metabolic pathway of phenylalanine, two chemically logical 4VA synthetic pathways were predicted.
