BEIJING, Jan. 13 (Xinhua) -- The following is a summary of published science and technology news of China.
CARGO SPACECRAFT
The Tianzhou-6 cargo craft, tasked with carrying supplies for China's space station, separated from the station combination on Friday, according to the China Manned Space Agency (CMSA).
The cargo craft will re-enter the atmosphere in a controlled manner in the future, the CMSA said.
SPACE TRANSMISSION
A Chinese commercial satellite company has successfully achieved laser communications between satellites in orbit at a speed of 100 gigabits per second (Gbps).
The data transmission was realized between two Jilin-1 satellites, with the final data successfully downloaded on the ground. It marks the first time that the country has transmitted high-definition intersatellite remote sensing images at such a high speed.
The company, the Chang Guang Satellite Technology Co., Ltd. (CGSTL), has sent more than 100 Jilin-1 satellites into orbit to form a commercial constellation, and has conducted key technology verifications for laser communications between these satellites since 2021.
AI FOR ANIMALS
A Chinese research team has developed an artificial intelligence (AI) technology that addresses crucial challenges in accurately detecting animal social behavior, according to the Shenzhen Institute of Advanced Technology (SIAT) under the Chinese Academy of Sciences.
The new technology, Social Behavior Atlas (SBeA), developed by researchers from the SIAT, can identify similar-looking animals with more than 90 percent accuracy, eliminating the need to define social behavior categories in advance, which may help discovery new, undefined differences in animal social behavior.
The new algorithm can also effectively synthesize a large volume of new data and train models with higher accuracy, thus obtaining more accurate 3D social gesture estimation results, said Wei Pengfei, correspondence author of the study. ■
