BEIJING, Sept. 10 (Xinhua) -- The following is a summary of published science and technology news of China.

LUNAR SAMPLE

A collection of glass beads retrieved by China's Chang'e-5 lunar mission revealed that the moon might have been geologically active as recently as 120 million years ago.

Lunar samples obtained prior to the mission indicated that the moon's volcanic activities had ceased approximately 3 billion years ago, suggesting it had become a "dead planet." However, the basaltic rock fragments returned by Chang'e-5 suggest a more recent period of volcanic activity, dating back to just 2 billion years ago.

PLANT STUDY

Researchers from the Xishuangbanna Tropical Botanical Garden under the Chinese Academy of Sciences have discovered a new firmoss species in southwest China, an extract of which has been proved to be effective in the treatment of Alzheimer's disease.

The new species, which is later named Huperzia crassifolia, was discovered during a medical plant inventory research in Guizhou Province.

MARINE MICROORGANISMS

A collaborative team of scientists from China, Britain, and Denmark has constructed a comprehensive global marine microbiome database, demonstrating the potential of marine microorganisms for marine science research and biotechnological and biomedical applications. Enditem
