WEEKLY REVIEW(Dec.14-20)
Chinese Internet Satellite Group Launched
China sent the first group of low Earth orbit satellites for a satellite Internet constellation from the Wenchang Space Launch Site in south China's Hainan province on December 16. The launch marked the 552nd mission of the Long March series carrier rockets.
New Pattern in Virus Transmission Uncovered
A Chinese research team has uncovered a new pattern in virus transmission through synthetic biology techniques. The research discovered that the faster the directional movement of bacterial populations, the more easily infected bacteria are discarded by the moving group, eventually leading to a population composed entirely of healthy bacteria.
Cancer-fighting Nuclides from Rare Earth Minerals
Chinese researchers have extracted high-purity lead-212 and bismuth-212 nuclides from rare earth minerals, which are known for their potential in treating various cancers. The breakthrough holds significant importance for achieving self-sufficiency in the production of critical medical nuclides in China.
Complex History of Human Gene Flow Revealed
An international team has estimated the genomes of 300 modern and ancient humans, including 59 individuals who lived between 2,000 and 45,000 years ago. The research helps to understand the effects of gene function and gene flow on human ancestors, and the results provide more precise details of the complex history of gene flow from the Neanderthals, an extinct species of archaic humans, to modern humans.
First Proof of Heaviest Antimatter Hypernucleus
The first ever evidence of antihyperhelium-4, which is composed of two antiprotons, an antineutron and an antilambda, has been discovered by an international team. The result represents the first evidence of the heaviest antimatter hypernucleus at the Large Hadron Collider, the world's largest particle accelerator, according to the European Organization for Nuclear Research. It provides new clues for scientists to further uncover the mystery of the matter-antimatter imbalance in the universe.
