BEIJING, Nov. 15 (Xinhua) -- The following is a summary of published science and technology news of China:


An AI-driven robotic chemist, developed by Chinese scientists, has automatically synthesized and intelligently optimized catalysts for the oxygen evolution reaction from Martian meteorites, offering a highly efficient and energy-conserving solution for the production of oxygen on Mars.

Using a machine-learning model, the AI chemist automatically and swiftly identifies the optimal catalyst formula from more than three million possible compositions. This groundbreaking discovery demonstrates the feasibility of the AI chemist in the automated synthesis of chemicals and materials for Mars exploration, according to the study published in the journal Nature Synthesis.


A team of Chinese scientists has confirmed the first live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line, which paves the way for scientists to use chimeric primates to study human diseases.

The experiment demonstrated that the monkey stem cells, a type of cell able to develop into many different cell types, could efficiently contribute to placental tissues outside the embryo and germ cells.

The research team from the Center for Excellence in Brain Science and Intelligence Technology and the Guangzhou Institutes of Biomedicine and Health under the Chinese Academy of Sciences, bred the chimeric monkeys using crab-eating or long-tailed macaques.


The Chinese government has unveiled an eight-year action plan for cancer prevention and treatment, aiming to achieve an overall five-year survival rate of 46.6 percent among cancer patients by 2030.

The plan, covering the 2023-2030 period, was jointly formulated by 13 government agencies, including the National Health Commission.

According to the plan, by 2030, the ability of cancer screening and early diagnosis and treatment will be significantly enhanced, the rising trend of cancer incidence and mortality will be curbed, and the burden of patients treating such diseases will be under control. Enditem
