Chinese scientists reveal how climate shift enhanced Jurassic biodiversity in East Asia
Science China PressPeer-Reviewed Publication
A Chinese research team has shown how a climate shift from wet to sub-humid conditions 167 million years ago reshaped East Asia’s landscapes, driving an increase in biodiversity in the Yanliao Biota. Published in National Science Review, the study highlights how varied habitats drove the evolution of early mammals, dinosaurs, and insects in the North China Craton.

Human oocyte quality and reproductive health
Science China PressPeer-Reviewed Publication
Oocyte quality is the key limiting factor of female fertility. However, compared with other species, the research and understanding of human oocyte quality and human reproductive health is limited. This review will highlight the current understanding of the physiological and pathological factors on human oocyte quality and discuss the potential treatments. In physiology, researchers discuss the regulation of the hypothalamic-pituitary-gonadal axis, granulosa cells, key subcellular structures, maternal mRNA homeostasis, the extracellular matrix, maternal microenvironment, and multi-omics resources related to human oocyte quality. In pathology, they reviewed the hypothalamic-pituitary-gonadal defects, ovarian dysfunction including premature ovarian insufficiency and polycystic ovary syndrome, human oocyte development defects, and aging. Furthermore, they outline the emerging scientific prospects and challenges for future mechanisms exploration and clinical treatment. This review seeks to deepen our understanding of the mechanisms regulating human oocyte quality and to provide novel insights into clinical female infertility characterized by defects in oocyte quality and oocyte development.
