According to the British "Daily Mail" report, American scientists have successfully deciphered 80% of the genome of this prehistoric behemoth through a group of mammoth hairs. Although this is a dull hair, it has made scientists take another step forward on the road to resurrection.
Scientists have compiled the DNA of this prehistoric beast through a sample of hair that has been permanently frozen in Siberia with a mammoth corpse that has been frozen for thousands of years. The genetic code gives scientists a new understanding of the evolution of mammoths, and shows that they are much closer to modern elephants than previously thought. The discovery also allowed researchers to clarify the genetic structure of the elephant and resurrect the mammoth that had been extinct for a long time.
Scientists used the DNA obtained from the remains of two mammoths found in the Siberian permanent freeze zone to conduct a study similar to the sci-fi blockbuster Jurassic Park. American scientists reported in Zui's new scientific journal Nature that one of the two mammoth corpses has been buried underground for 20,000 years, while the other has been buried for at least 60,000 years. By carefully analyzing their DNA, the research team has compiled 80% of the mammoth genome or genetic code.
This study shows that the two mammoths are closely related and the 99.4 genes are identical. In addition, the analysis also shows that 6 million years ago, mammoths and modern elephants went to different evolutionary paths. At the same time, humans and chimpanzees also embarked on the same evolutionary path as them. Two million years ago, the mammoth was divided into two, one group was extinct 45,000 years ago, and the other group disappeared from the earth at the end of an ice age after zui 10,000 years ago.
The male mammoth is about 10 feet high (about 3 meters) and the female is relatively short. Their fangs are long and curved, and the hair of the abdomen is up to 3 feet (about 0.9 meters). So far, scientists have discovered about 40 mammoth bodies in Siberia. The reason why American scientists who have implemented the new study of Zui use DNA extracted from mammoth hair is because they are better preserved than the DNA of other parts of the mammoth.
Some researchers have been suggesting the use of frozen mammoth skin or hair to clone mammoths. Stephan Schuster, a professor at Pennsylvania State University who led the study, said: "In theory, by deciphering this genome, we can get important information, and one day, as long as the unique mammoth DNA sequence Incorporating into the genome of modern elephants, this information may help other researchers resurrect mammoths."
However, Dr. Michael Bunce, director of the Paleontology DNA Laboratory at Murdoch University in Western Australia, poured a cold water on Professor Schuster. He said: "Mastering the DNA code of a certain organism does not mean that we can achieve the good wishes of reviving the extinction organism through genetic means."
Traditional
convenience foods need to be soaked in boiling water for consumption.
Some special people, such as wilderness adventures, tourism, troops, and
police officers, cannot be eaten without boiling water. Self-heating
Rice does not need boiling water when cooking, no need for thermal
power, tear open the outer packaging, pour the pure water bag inside it
into the heating bag, the water and the heating bag will automatically
mix and heat up, steam the rice and the dishes, 8-15 minutes Edible.
Decommissioning
the ingredients of the Self-Heating Rice heating package: Inventing a
multi-purpose self-heating bag, mainly using roasting diatomaceous
earth, iron powder, aluminum powder, coke powder, activated carbon, salt
to form a bag, which can be heated to 60 °C It
can be used for heating in winter, medical hot compress, adding
quicklime, sodium carbonate and water. The temperature can be raised to
120 °C to heat meals or steamed food. The temperature is kept for 20
minutes to 100 ° C for 60 minutes and 60 ° C after 60 minutes. The
material used in the winter heating and hot compressing can be
repeatedly used, and after being used, it can be mixed with quicklime
and sodium carbonate, and then heated to heat the food.
