Recently, the scientific research team of the Institute of Tibetan Plateau of the Chinese Academy of Sciences has quantitatively restored the uplift and demise process of the central valley of the Qinghai-Tibet Plateau from 38 million to 29 million years ago through comprehensive research in multiple fields and means such as tectonic geological evolution, deep dynamic processes of the lithosphere, paleothermal temperature, paleogetological analysis and paleoclimate simulation, and revealed that the uplift of the central valley is the beginning of the huge impact of the Tibetan Plateau on the geosphere environment. The results were published online on February 10 in the international academic journal Science Advances. (Source: CCTV News Client)

Mulberry tree is an important ecological and economic tree species. The latest research by mainland researchers has found that the fusion fracture of chromosomes makes mulberry trees have two sets of chromosome bases. This study shattered the previous perception that "an organism has only one set of chromosome bases" and laid the foundation for accurately mapping the "family tree" of mulberry tree kinship. The research results were published online in the academic journal Horticultural Research. (Source: Xinhua News Agency)
Recently, the scientific research team of the Chinese Academy of Sciences has made new progress in the research of wheat genome editing disease resistance breeding, and the scientific research team has screened a new type of disease-sensitive gene mutant Tamlo-R32 in a large number of genome-edited wheat mutants. This mutant exhibits complete resistance to powdery mildew while growing and developing normally and yielding normally. This research is an important advance in wheat powdery mildew resistance breeding, and also fully demonstrates the huge application prospects of genome editing in modern agricultural production.

● As one of the most successful evolutionary clades of scaly animals, the monitor lizard family is widely concerned for its multi-sized members and the mystery of its origins. A collaborative team of Chinese and foreign scientists studied a fossil of a new genus of basal stems from Hubei, China, about 56-52 million years ago, that the Archaeopteryx Lee monitor lizard supplemented the evidence chain of the Asian origin theory of the lizard family, indicating that there was a transition stage in Asia from the monitor lizard type to the monitor lizard family.
