BEIJING, Dec. 1 (Xinhua) -- The following is a summary of published science and technology news of China.

COVID-19 OMICRON VARIANT

China's current prevention and control strategies are effective against the COVID-19 Omicron variant, the National Health Commission (NHC) said on Tuesday.

China will stick to its pandemic prevention and control policy, which aims to curb the transmission of the virus from abroad and simultaneously prevent the virus from resurging in the country, NHC spokesperson Mi Feng said at a press conference.

MATERIAL FOR SPACECRAFT

Chinese researchers have developed a new type of double-layer polyimide nanocomposite film, which can be applied on the external surfaces of spacecraft.

The researchers from the University of Science and Technology of China generated a new polyimide-based nanocomposite film with greatly enhanced mechanical properties and atomic oxygen resistance by integrating mica nanosheets with polyimide into a unique double-layer nacre-inspired structure with a much higher density, according to their recent research article published in the journal Advanced Materials.

ANTARCTICA METEOROLOGICAL STATIONS

Two more meteorological stations of China in the Antarctica began formal operation Wednesday to help the country obtain long-term and continuous observational data on the continent, said the China Meteorological Administration.

The two automatic stations, located at China's Antarctic research bases, Kunlun and Taishan stations, were set up by China's Antarctic expedition teams in 2017 and 2012, respectively.

The station operation will help observe the Antarctic ice sheet and further advance the global weather forecasting, said Wang Yi, deputy director of the World Meteorological Centre (Beijing) Office. Enditem
