Canadian scientists recently discovered that a substance extracted from the genetically engineered sheep that has been implanted with a spider gene from the body can extract a substance that can be used to make high-strength silk yarn. This was reported in the 12th issue of Geography in Germany in 2002. A discovery. According to reports, a scientist from the Canadian company Quebec named Nexia (NEXIA) implanted a gene from a spider species of the genus Arachniella into a dwarf lamb planted in Nigeria and found it in this genetically modified sheep. The secreted milk contains a special substance that can be used to "weave" high-strength silk threads like a spider. Scientists said that they specially processed the milk secreted by the genetically modified sheep and separated the fat, protein, and moisture contained in the sheep. After the goat milk contained some silky sticky substances, the residual substances were By squeezing out an extremely small nozzle, it is possible to produce a thread with good physical properties. This thread is not only highly resistant to pull, but it is also particularly light. Even with the same quality, the strength exceeds that of steel. Scientists say, This kind of material that they call "bio-steel" will have a wide range of applications in the medical and other fields. It is reported that the company’s researchers have done experiments on implanting a certain spider gene into animals such as hamster larvae. In collaboration with the U.S. military, they have also obtained better-strength silk fiber materials. Earlier this year, the United States "Science" magazine reported similar results.
