BEIJING - The fifth batch of scientific experimental samples from China's Tiangong space station has arrived in Beijing, following the return of the Shenzhou XVI crew on Tuesday.

Samples of 19 scientific experiments, weighing around 25 kg, were brought back to Earth, including liver cells, protein and nucleic acid, Arabidopsis plants, rice seeds, radiation-resistant microbes and some chemical materials.

Scientists will conduct life and material experiments to study the impacts of a microgravity environment on these samples, the Chinese Academy of Sciences said

They have been delivered to the Technology and Engineering Center for Space Utilization under the Chinese Academy of Sciences.
