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.

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.

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.

In natural environments, animals often rely on odors to evaluate the nutritional value of food. Odor molecules from food sources provide predators with crucial information regarding nutritional quality and palatability.

Chinese researchers have developed a novel method to efficiently engineer natural killer (NK) cells for cancer immunotherapy.
