BEIJING, Jan. 2 (Xinhua) -- The following is a summary of published science and technology news of China:

MARSH WETLANDS

On the Qinghai-Tibetan Plateau, Chinese scientists recently discovered the phenological dynamics of wetland vegetation in response to climate change.

The study, led by researchers from Northeast Institute of Geography and Agroecology of Chinese Academy of Sciences, was recently published on the journal Global Change Biology.

According to the study, the Qinghai-Tibetan Plateau, which holds 20 percent of China's wetlands, plays a critical role to the regional carbon cycle. Understanding the influence of climate change on marsh vegetation requires an examination of the phenological dynamics.

FAST TELESCOPE

Astronomers detected a scintillation arc in the spectrum of fast radio burst (FRB) for the first time using China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish and most sensitive radio telescope.

FRBs are mysterious radio flashes lasting only a few thousandths of a second that were confirmed in 2016 to originate from the cosmos. There is still no explanation for their origins.

An international group led by the researchers from the Chinese Academy of Sciences' National Astronomical Observatories presented the interstellar scintillation analysis of FRB 20220912A during its extremely active episode in 2022.

SELF-DRIVING

An urban air traffic center for self-driving passenger aircraft opened in China's southern metropolis of Shenzhen and started urban air traffic business recently.

The urban air traffic demonstration center, located in Bao'an District, includes an apron, a hangar, as well as its command and dispatch center on 4,500 square meters of land.

It supports low-altitude urban air mobility (UAM) business, which is likely to expand in the future to include UAM travel for sightseeing, science and technology projects and science popularization education. Enditem
