Science Saturday: Moon exploration, cruise ship, organ regeneration and nuclear-contaminated water
By Tech It Out
The China Manned Space Agency has begun preparations to land the first Chinese person on the moon by 2030. The agency also described the process as involving the launch of an unmanned moon orbiter and lander, as well as a new-generation manned spacecraft. After docking with the orbiter, a taikonaut will enter the lander residing inside the orbiter and land on the moon. The research and construction work for the project is already underway with a new launchpad in the pipeline at the Wenchang Satellite Launch Site in south China's Hainan Province.
China cruise ship
China's first domestically built large cruise liner, Adora Magic City, has completed its second and final trial voyage. The six-day test, which started on September 7, mainly focused on the ship's speed, maneuverability and internal infrastructure operation. There were more than 1,300 people on board including technical personnel and inspectors. The cruise ship was built by the China State Shipbuilding Corporation in partnership with China Telecom, who installed 5G on the ship. Adora Magic City is expected to begin operations by the end of 2023.
Human organ regeneration
Under the Chinese Academy of Sciences, scientists used an editing tool to engineer certain genes in "human induced pluripotent stem cells" to form kidneys in pig embryos that were genetically modified to lack the ability to grow a kidney. After a three-to-four week gestation period, researchers harvested five embryos with organized human-pig middle-stage kidney structures. It supports the idea that generating a humanized organ in pigs may offer a viable alternative to the shortage of human organs for transplantation. The study published in the journal Cell Stem Cell says that the research may open a new window for studying human kidney development.
Fukushima contaminated water
Japan has completed the discharge of the first batch of nuclear-contaminated water from the crippled Fukushima power plant. The Tokyo Electric Power Company, which operates the plant, said on Monday that a total of 7,800 tonnes of treated water had been released. The company said that a second discharge of the same volume will be released by the end of September. The process began on August 25 and will continue for at least 30 years. The controversial discharge has been condemned by local fishing communities and neighboring countries, including China, which has imposed a blanket ban on all Japanese aquatic products.
