According to a report in the British "Daily Mail" on the 18th, Japanese scientists said recently that they plan to use cloning technology to create a living woolly mammoth within 5 years. Mammoths are species that survived the Ice Age and have been extinct for more than 5,000 years. Japanese scientists extracted intact DNA cells from the mammoth zygomatic bones displayed in the Russian Institute. Scientists plan to insert it into the empty cells of ordinary elephants, artificially grow and divide them, and then obtain an embryo containing the hairy elephant genes. Then put the embryo into the uterus of a mother elephant, hoping that the mother elephant can produce a small mammoth after more than 600 days of pregnancy. Akira Iritani, head of the research team, said that elephants were chosen to breed embryos because elephants are the species most closely related to mammoths in modern species. The entire research and operation process need to be careful. If cloned mammoths are born successfully, scientists will continue to study their genetic and ecological characteristics in order to infer the cause of the extinction of mammoths. (Begonia) Metallographic Cutting Machines Cutting is the first step of material analysis. The selection of cutting machine and cutting wheel must comply with the geometric size and material characteristics of the sample. The perfect metallographic cutting should avoid microstructure thermal damage and deformation, and preserve the necessary accuracy and efficiency.Hardness and ductility are the two main parameters for selecting the cutting wheel. The best choice of the cutting wheel depends on the size, hardness and ductility of the material and the equipment used. Trojan's cutting products speak with facts and the cutting process is simple, fast and accurate.
