BEIJING, Jan. 15 (Xinhua) -- The following is a summary of published science and technology news of China:

TIANZHOU-7 CARGO SPACECRAFT

The combination of the Tianzhou-7 cargo spacecraft and a Long March-7 Y8 carrier rocket was vertically transferred to the launching area on Monday. The cargo spacecraft will be launched in the near future at an appropriate time, according to the China Manned Space Agency.

The facilities and equipment at the Wenchang Spacecraft Launch Site in China's southern island province of Hainan are all in good condition, and various pre-launch function checks and joint tests will be carried out as planned, the agency said in a statement.

ULTRA-LOW TEMPERATURE

Chinese scientists have achieved ultra-low temperature refrigeration -- below minus 273 degrees Celsius -- in a recently synthesized supersolid candidate.

The temperature was reached without the use of liquid helium, a conventional material that has long been used in ultra-low temperature refrigeration, according to a paper published in Nature.

Supersolid is a quantum state of matter that possesses a solid structure and shows superfluidity simultaneously. A team of researchers at the University of Chinese Academy of Sciences and their collaborators proved the presence of this exotic state in the synthesized supersolid candidate, a cobalt-based quantum magnetic material.

ANIMAL SOCIAL BEHAVIOR

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, 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.
