The following is a summary of published science and technology news of China.

TREE RING DATA

Chinese researchers have provided new insight into the regional climate history in southwest China's Yunnan Province through scientific analysis of the annual rings of trees in that region.

The study was recently published in the journal Palaeogeography, Palaeoclimatology, Palaeoecology.

The researchers from Xishuangbanna Tropical Botanical Garden (XTBG) under the Chinese Academy of Sciences, collected samples of Tsuga dumosa, one of the oldest local tree species, from the Wuliang Mountain area in central Yunnan.

DUST WEATHER FEEDBACK MECHANISM

Chinese researchers have made significant headway in the study of the feedback mechanism between dust aerosol and dust weather. This research is instrumental in aiding the prevention and control of dust storms, according to Lanzhou University.

The study provides strong support for a more comprehensive understanding of the dust weather feedback mechanism, improving dust forecasting and dust control capabilities, said Chen Siyu, leader of the study and professor with the College of Atmospheric Sciences of Lanzhou University.

YOUTH SPACE INNOVATION COMPETITION

The finals of the 2023 National Youth Space Innovation Competition were launched on Monday in Wenchang City of south China's Hainan Province, providing teenagers with an opportunity to share their wisdom on aerospace innovation.

Speaking at the finals, Fang Xiangming, deputy Party chief of the China Aerospace Science and Technology Corporation (CASC), said that young people are not only the hope of the country's future, but also an important force to promote innovation.
