The eight extraordinary genetic experiments: Nazi attempts to make twins'

The eight extraordinary genetic experiments: Nazi attempts to make twins' city
November 19 news of scientific and technological news Beijing time of Sina, according to medias of foreign countries, since the mankind knew gene and hereditary basic principle, never disconnected over further exploration of the genetic secret. The scientists have been attempting to change or optimize various hereditary genes through various experiments all the time too. Recently, the foreign media chooses the eight strange genetic experiments in the history of mankind, include Nazi's scientist's attempting to make twins' city, hybridization spider's goat,etc..

1,The scientist of Nazi attempts to make twins' city

Nazi scientist attempt, make the intersection of twins and urban Joseph - the intersection of door and Georgia, rein in it is the intersection of Nazi and the intersection of Germany and famous anthropology with gene that study expert, he is known as because of genetic experiment of notorious twins' human body too " The dead angel " . At that time, one dose of main tasks tied tight created a new excellent nationality for the third kingdom of Hitler's on the door. From 1943 to 1945, he resides at Auschwitz Concentration Camp, utilizes the twins of Jew in the concentration camp to carry on human body and genetic experiment, attempt to find and change the chromosome and make the method of twins, he hopes to raise the refined profit to fit the ethnic group's birth rate artificially through this kind of method. Some historians think, one dose of genetic experiments tied tight may have already made some achievements on the door. Over many years, scientist guide the intersection of Togo and many twins of Iraq town birth rate to the intersection of Brazilian and bank high to feel very much mysterious, but been failing to find the answer all the time. Guide the intersection of Togo and many the intersection of Iraq and town in bank, a woman bears twins in the every 5 pregnant women probably, and babies of twins bearing it are for the most part green eyeballs of golden hair. And this is exactly the excellent and national characteristic that the scientist of Nazi firmly believes, dose ties tight this small town on the door but also quite interested in, he has attempted to make one and guide many similar twins' cities of his town of Togo with the bank too. Guide the intersection of Togo and many local of Iraq town introduction according to bank, until initial stage of the sixties of last century, dose ties tight and also frequently calls on this town on the door. At first, he appears in the capacity of veterinarian, later on he practises medicine on the small town, the target of mainly practising medicine, as the women in the small town. After the war for escape legal sanction, door dose tie tight in drift in Argentinian, Brazilian, Paraguay and other places. Passed away until 1979, dose tied tight and made the excellent nationality and twins dream of the city and failed to realize finally on the door.

2,Can produce the biological steel wire while hybridizing spider's goat

Can produce the biological steel wire spider to hydridize with the goat one while hybridizing spider's goat, it sounds as if that seems to be Arabian Nights, but there really exists such a thing in fact. Hereditary scientists once planted the spider DNA chosen carefully into goat's embryo, attempt to make a spider goat hybridizing. What do the scientists carry on this strange experiment purpose? They are for obtaining the special gossamer. The scientists think, some special gossamer is more precious than the gold. Biological scientific & technical corporation cooperates with the national biochemical command centre of ground force of U.S.A. together in a summer in Quebec of Canada, collect spider's gene to plant into the goat in the body from spider, has made one and hybridized goats. Participating in the experimental spider actually can produce a kind of special gossamer. The intersection of hybridization and goat born, appearance seem remain goat, too like goat various behavior, but it can produce a kind of sheep's milk enriched with gossamer albumen. The scientists utilize the special spinning procedure again, spin the gossamer albumen in the sheep's milk into an artificial genetic spider silk. Such artificial gossamer not only has softness and gloss like silk, but also several times better even than steel wire of intensity, so this kind of gossamer is known as the biological steel wire, it is quite extensive to employ. Certainly, there is little amount of production of gossamer albumen of a goat, if cultivating in a large amount, can well meet demands of practical application.

3,The scientist revives an extremely icy mouse

It is one piece icy for scientist to revive the intersection of mouse and one mouse freeze 16 year behind the death extremely, Japanese scientist drawing the gene clones a new mouse from their in the body, this is the mankind success clones the frozen animal for the first time. Researchers claim, their research results can promote the well-being of mankind too, can also be used for reviving some extinction species, such as the mammoth, sabertoothed tiger,etc.. But the critic thinks, with the maturity of this technology, the human one will be cloned in the near future. This is quite terrible a technology, will also cause the confusion of ethics. The relative of the death is frozen, perhaps probably the process will be cloned and revived again in the future. Before this though scientists have already cloned out a lot of animals, has utilized the cells alive, have never utilized frozen cells.

4,The mosquito of the corrective gene can prevent and control disease

Mosquito of corrective gene can prevent and control the intersection of disease and scientist, make a only anti- malaria mosquito through method that gene revised once, this kind of mosquito is more vigorous than other insects that can carry disease. People can imagine, perhaps in the future this kind of technology contributes to disease prevention and control. In the experiment, the scientist plants a kind of very anti- malaria gene into in mosquito's gene at first, revise mosquito's gene. Then, the mosquito after and then revising this kind of gene puts into the field, the mosquito passes such fine gene to all mosquitoes through mating. In the experiment, the scientists not merely plant into defending the malaria gene in mosquito's body, it can make mosquito's eyes give out the gene of the fluoro to still plant into another kind. In this way, scientists can discern them very easily. Having had these genes, it is parasitic that the mosquito can prevent the malaria parasite. However, this technology is still at initial stage at present. Scientist think until the following 10 years have more such genetic revision put into field by insect perhaps while being about. Because the parasite exists to the host's health too and threatens, the mosquito of this kind of corrective gene will not be interfered with by the parasite, so theirs is vigorous.

5,The taste reason to the color of different gender evolves by oneself

The taste reason to the color of different gender evolves by oneself
As everyone knows, woman like pink generally, and men mostly like blue. Though everybody knows this kind of phenomenon, nobody knows why. The scientist thinks, the reason to cause this kind of phenomenon is numerous, among them there is a factor of the cultural tradition, also there is instinct of evolving. Scientists of Britain Newcastle university Bert and Lin YaZhu (transliteration) in Hull Have made investigations to 208 volunteers separately, and compared the investigation result with and analyzed. Included Chinese students by the students investigating, there are British students too. The scientists find, Chinese students like red very much, because red represents in China the good luck is and joyous. This is influence of a kind of cultural tradition. However, no matter Chinese interviewees or British interviewees, the studying of different gender? it moves bright to be difficult to measure the intersection of and the intersection of port and boundless and indistinct , bungle the intersection of and Lang fight Feng warm up the intersection of and competent to impose Le, Huo of Ge, crossing Du Tu while being fierce? Pu keep fit live abroad and hold in the mouth nice food live abroad very much circles of Zhangs of fresh to wrap up to admire E of 1 Mao impose to censure demand You Miaos evil admire s skillful take off rifle block to cook of Lu of last Ping Father's crab The toe warm up 's tomb and take on and walk the light condyle of larva of a tapeworm or the cercaria of a schistosome of Miao You's brain of garden is rolled over?

6,The genetic switch technology makes the tadpole longer than third eyes

Genetic switch technology let tadpole longer than third eyes if scientist can utilize stem cell produce the intersection of eyeball and of mankind, then a lot of blind persons or eye illness patients would get rid of and lose one's sight etc. from then on worried. In 2007, British scientist utilizes the genetic switch technology to succeed in cultivating the third eyeball in the laboratory on tadpole's head. This news is a huge good news to blind person. Utilizing this kind of technology, stem cell's scientists may really realize they give a new lease of life to the dream of the eyeball. In these decades, the scientists have been looking for and controlling the closing and have been good for the gene of eyes development. In the experiment, Professor Dell, scientist of British Warwick university, has injected into a special enzyme in the embryo of the frog, the tadpole which this frog gave birth to out all had a surplus eye finally. This discovery lets scientists realize, this kind of enzyme can promote the development of the eyes system in the embryo. When the scientist tries to inject this kind of enzyme into embryo's other development positions again, more strange phenomenon has taken place. This kind of enzyme has caused long last third eyes on tadpole's belly even tail. The scientist is attempting to find the method to foster human eyeball through this kind of technology at present.

7,Dutch company trains the cow with human gene

Dutch company trains the cow with human gene and carries on one's shoulder or back Ramphal bright biotech company and passes genetic engineering, train a batch of cows with human gene. In the milk which such genetic cow produces, contain rich amount of human milk irons and transmit albumens. According to website of this company, this kind of albumen usually exists in the human tears, lung part secrete multi-type such as thing, milk humorally. It can resist the invasion of many kinds of bacteria, can prevent eyes and lung from infecting, can equilibrate a group of quantity of the fungus in the intestines, can promote the stomach to absorb, play an essential role in the immune system of the human body. Scientist transmit albumen, carry on toxicity measure to the the intersection of milk and iron, they find take orally the the intersection of milk and iron transmit albumen, can cause side effect.

8,The American scientist changes the trees gene to draw the cellulose

The American scientist changes the trees gene to draw the cellulose if the trees can get 30 meters long within 6 years, or can be as convenient if gathering in as crops in the farmland, then they can become main substituent of fuel of petrochemical industry. American researcher of Purdue University utilize genetic technology try, hybridize, appear, can produce biological trees of fuel at a low price while being convenient. The scientists focus sight on a compound known as lignin plant cell wall on one's body. This kind of compound contributes to increasing the supporting strength of the cell wall in the cell wall, but hindered cellulosic abstraction, and the cellulose exactly produces a needed in place of ethanol of fuel and is the candy compound is sucked. The fund that this project has got American Ministry of Energy is supported, Purdue University Clint - check the characteristic that general three scientists of tying tight etc. plan to make use of genetic means to change the lignin in order to draw the cellulose.
