BEIJING, Oct. 22 (Xinhua) — The following is a summary of published science and technology news of China.

CHANG’E-5 SAMPLES

A Chinese group analyzed lunar samples returned by China’s Chang’e-5 mission and proposed a new mechanism for how young volcanos took shape on the cooling moon 2 billion years ago.

Scientists previously speculated that the elevated water content or radioactive elements in the lunar interior might have driven volcanism in the late stage of the moon’s life. But the Chang’e-5 data found its mantle source region both dry and lacking in heat-producing substance.

The study published on Saturday in the journal Science Advances showed that the mantle melting-point depression due to the presence of fusible, easily-melted components could generate young lunar volcanism.

GUT BACTERIA RESEARCH

A study by Chinese scientists and their U.S. counterparts has identified a type of bacteria in our gut that can effectively degrade nicotine, a harmful ingredient in tobacco that causes addiction and a slew of health risks including fatty liver disease.

A colony of gut bacteria was found to have reduced intestinal nicotine concentrations in nicotine-exposed mice, according to the latest study published in the journal Nature.

DEEP SPACE EXPLORATION LABORATORY

China’s deep space exploration laboratory launched campus recruitment, aiming to attract more young talents to devote themselves to the country’s deep space exploration, according to the China National Space Administration (CNSA).

Co-established by the CNSA, Anhui Province, and the University of Science and Technology of China, the laboratory is headquartered in Hefei, the capital city of Anhui. It started operation in June this year.
