BEIJING, Feb. 5 (Xinhua) -- The following is a summary of published science and technology news of China.

LUNG CANCER AI DETECTOR

Chinese scientists have developed an Artificial Intelligence (AI) assisted testing tool to detect early-stage lung cancer.

The study published on Thursday in the journal Science Translational Medicine described the Lung Cancer Artificial Intelligence Detector that may play a part in the early detection of lung cancer or large-scale screening of high-risk cancer populations.

SPECIES BIODIVERSITY ON QINGHAI-TIBET PLATEAU

Chinese researchers have discovered geographical isolation, natural selection, and hybridization could have together promoted the species diversification of numerous plant genera on the Qinghai-Tibet Plateau.

Gene flow has been widely detected during the speciation processes of all examined groups, suggesting that natural selection may have played an important role during species divergence in this region.

In addition to geographic isolation, natural hybrids have been recovered in almost all species-rich genera. This suggests that numerous species in this region are still on the speciation pathway to complete reproductive isolation.

GREEN REFRIGERATION TECHNOLOGY

Chinese scientists have discovered a promising green refrigeration technology that may replace traditional refrigerants represented by freon, a greenhouse gas that leads to severe climate problems.

The research team led by Tong Peng at the Institute of Solid State Physics at the Hefei Institutes of Physical Science under the Chinese Academy of Sciences has found excellent cooling performance in n-alkanes through solid-liquid state transition driven by high pressure. The discovery provides a new perspective for developing eco-friendly refrigeration technology. Enditem
