BEIJING, Feb. 22 (Xinhua) -- The following are the highlights of China's science news from the past week:


The China-France Oceanography Satellite (CFOSat) has been put into service after completing in-orbit tests, according to the Ministry of Natural Resources.

During the 8-month in-orbit test, the satellite acquired high-accuracy remote sensing data with its scatterometer and wave spectrometer, and the ground stations have met the requirement of data processing, said Liu Jianqiang, chief scientist of the satellite.


Convalescent plasma therapy has proved to be effective on severe cases of novel coronavirus disease (COVID-19), a Chinese official said on Friday.

More than 100 patients who have recovered from COVID-19 have donated plasma and the plasma can be prepared into therapeutic products to treat 240 patients with severe and critical symptoms, said Xu Nanping, vice minister of Science and Technology, at a press conference in Beijing.

The therapy so far proves effective on the patients, said Xu.


The maiden flight of the Long March-5B rocket carrying a trial version of China's new-generation manned spaceship is expected to take place in April, indicating the imminent start of construction of China's space station.

The rocket, the prototype core capsule of the space station and the experimental manned spaceship are undergoing tests at the Wenchang Space Launch Center on the coast of south China's island province of Hainan.


China sent four new technology experiment satellites into planned orbit from the Xichang Satellite Launch Center in southwest China's Sichuan Province Thursday.

The satellites, launched by a Long March-2D carrier rocket at 5:07 a.m. (Beijing Time), will be mainly used for the new Earth-observation technology experiment.

Thursday's launch was the 326th mission of the Long March rocket series.


Chinese experts, based on the result of clinical trials, have confirmed that Chloroquine Phosphate, an antimalarial drug, has a certain curative effect on the novel coronavirus disease (COVID-19), a Chinese official said here Monday.

The experts have "unanimously" suggested the drug be included in the next version of the treatment guidelines and applied in wider clinical trials as soon as possible, Sun Yanrong, deputy head of the China National Center for Biotechnology Development under the Ministry of Science and Technology (MOST), said at a press conference.
