[Photo/Xinhua] HARBIN - The relay satellite for the Chang'e 4 lunar probe, which is expected to land on the far side of the Moon later this year, has been named Queqiao - magpie bridge. The name was announced by the China National Space Administration (CNSA)Tuesday, China's Space Day. In a Chinese folktale, magpies form a bridge with their wings on the seventh night of the seventh month of the lunar calendar to enable Zhi Nu, the seventh daughter of the Goddess of Heaven, to cross and meet her beloved husband, separated from her by the Milky Way. Together with the relay satellite, two microsatellites, developed by the Harbin Institute of Technology, will also be sent into orbit. The two microsatellites were named Longjiang 1 and Longjiang 2. Work on the Chang'e 4 lunar probe is progressing well, said Li Guoping, a spokesman of CNSA. Chang'e 4 will carry payloads for Germany, the Netherlands, Saudi Arabia and Sweden, The far side of the mood is of great scientific interest, but landing there requires a relay satellite to transmit signals. The relay satellite will be sent into the halo orbit of the Earth-Moon Lagrange Point L2 in late May, and the Chang'e 4 lunar lander and rover will be sent to the Aitken Basin of the south pole region of the Moon about six months later. silicone wristbandmake custom bracelets onlinewristbands for eventscustom wristbands in bulkrubber bracelets cheap
[Photo/VCG] BEIJING -- Chinese scientists have designed a new screening method for hepatitis B carriers, to detect early-stage hepatocellular carcinoma (HCC), the most common type of primary liver cancer. The new method was developed by researchers from Cancer Hospital, Chinese Academy of Medical Sciences and Genetron Health, a biomedical company. Through a liquid biopsy that detects cell-free DNA somatic mutations in combination with protein markers, researchers can efficiently identify early-stage HCC cases of less than 3 cm. According to Yan Hai, one of the researchers, the method showed 100 percent sensitivity, 94 percent specificity and 17 percent positive predictive value in the validation cohort, proving it a feasible approach to identify early stage HCC. The research team will optimize this screening method through systematic research in a multi-center, large prospective cohort study, Yan said. After rigorous clinical validation, this method is expected to become a more convenient, non-invasive and standardized early screening program for liver cancer. The research was published in the US journal Proceedings of the National Academy of Sciences.
