China's Five-hundred-meter Aperture Spherical Radio Telescope (FAST), the world's largest single-dish radio telescope, has identified more than 900 new pulsars since its launch in 2016. The telescope provides astronomers around the globe with a powerful tool to uncover the mysteries and evolution of the universe, said Jiang Peng, chief engineer of the FAST. One of the important implications of the research on pulsars is to provide cosmic coordinates for possible future interstellar travel.
In a hospital in Wuwei, northwest China's Gansu Province, a medical facility consisting of large pieces of steel and complex coils occupies a building of 30 meters high. The high-speed carbon ions produced by it are channeled into the treatment room to kill the tumor cells of cancer patients. The advanced medical facility, called heavy-ion accelerator, is assisting human's fight against cancers. However, due to its large size, high production and maintenance costs, it has not been widely used in ordinary hospitals.
In a study recently published in the journal Science, a team of researchers led by Huang Yuanyuan from the Institute of Geographic Sciences and Natural Resources Research of the Chinese Academy of Sciences (CAS) and Zhang Ganlin from the Institute of Soil Science of the CAS, have quantified the global store of SIC, challenging the long-held view.
Chinese scientists have constructed a database of nutrient concentrations in Chinese lake sediments, which reveals their historical changes and can be used to predict water quality and environmental conditions in various lake areas.
