In a paper published in SCIENCE CHINA Earth Sciences, a research team systematically interpreted the key scientific issues such as the DO threshold, structural characteristics, distribution patterns, formation and maintenance mechanisms, and driving factors of the OMZ in the context of global change. It may provide important scientific basis for further exploring the coupling relationship between global change and oceanic OMZ, and for understanding marine hypoxia and deoxygenation issues from a global perspective

A remarkable new discovery is shedding light on one of the greatest survival stories in Earth’s history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence in the wake of the End-Permian Mass Extinction some 252 million years ago, the most devastating extinction event our planet has ever experienced. While countless species vanished, Lystrosaurus not only survived, but thrived in a world marked by extreme environmental instability, intense heat, and prolonged droughts.
