Xi'an's science achievements rank in national top 10

Two achievements from Xi'an – the transplantation of gene-edited pig livers into humans and the high-performance flexible tandem solar cells for aerospace applications – have been included in the 2025 Top 10 Scientific Advances in China, as announced on March 25 at the 2026 ZGC Forum Annual Conference in Beijing.

Launched in 2005, the selection for the Top 10 Scientific Advances in China has become a flagship activity showcasing major annual progress in China's basic research, encouraging scientists and researchers to scale new heights in science, and promoting the popularization of basic research to enhance public understanding.

The xenotransplantation of gene-edited pig livers into humans, accomplished by Xi'an's Air Force Medical University, systematically verified the feasibility of xenogeneic liver transplantation from two perspectives: donor modification and recipient regulation. This has achieved a major clinical breakthrough, providing the world with a Chinese approach to xenogeneic liver transplantation and laying a solid technical and theoretical foundation for future clinical applications.

The high-performance solar cells for aerospace applications were submitted by LONGi Green Energy Technology Co and Soochow University. A LONGi representative said that the study proposed an interface regulation strategy using a double-buffer layer and an indium cerium oxide thin film. The device's certified photoelectric conversion efficiency reaches 33.6 percent, and it is expected to be applied in various fields.
