BEIJING, May 16 (Xinhua) — The following is a summary of published science and technology news of China.
SYNCHROTRON RADIATION FACILITY
China has upgraded the Shanghai Synchrotron Radiation Facility (SSRF), a key sci-tech infrastructure to reveal the mysteries of the microscopic world.
The construction of upgrades on the SSRF passed the national inspection and acceptance in east China’s Shanghai on Wednesday.
The SSRF, which resembles a nautilus when viewed from above, was officially opened to users on May 6, 2009 as the first third-generation synchrotron light source in China’s mainland.
DINOSAUR TEETH
Four large dinosaur teeth unearthed in Guangdong Province have been confirmed by Chinese scientists to be from the Tyrannosauroidea group dating back 70 million to 66 million years ago, making it the southernmost fossil evidence of this taxon in China.
The four teeth can be traced back to the Maastrichtian stage, the most recent phase of the Late Cretaceous period. Three of these specimens were discovered in 2010 in the city of Sihui by an amateur fossil enthusiast who later donated them to a local museum. The other tooth was found at a construction site in the provincial capital Guangzhou in 2020 by one researcher and is currently housed in the collection of Sun Yat-sen University.
NEW PLANT SPECIES
Five new plant species have been discovered in the Yintiaoling national nature reserve in southwest China’s Chongqing Municipality over the past decade, the reserve’s administration center said.
The center has jointly cooperated with the Chongqing Natural History Museum, and some other local universities and scientific institutions, to conduct a comprehensive and special survey of biological resources in the reserve over the past ten years.
During this survey, researchers found that the reserve boasted a variety of rare and endangered species. Among the 3,595 species of vascular plants found in the reserve, there are 74 species of key protected wild plants, including 51 species at the national protection level.
