10 genetically modified creatures
Genetics - one of the sciences, whose rapid development awaits humanity in the coming years. Now even the scientists can not imagine all the possibilities that can open a person manipulating DNA, but some of the results of years of experience with the genome can already feel the every - the world's food is gaining popularity, plants and pets with altered DNA. If you want to make this the charming "mutant" or enjoy a meal with unusual properties, here are some options that modern genetic science can offer you.
1. Design children
The first "batch" of genetically modified babies was born in the year 2001. 30 infants had a DNA consisting of the genes of three parents - these babies were conceived using a method of transplantation of the cytoplasm, are now prohibited US Agency for Food and Drug Administration.
Initially, this method was developed for the fertilization with low fertility (ie, with low ability to conceive), but when one of the children in the further development, researchers found abnormalities in brain development, which could be a cause of autism, the experiments of this kind have forgotten.
Incidentally, infants with two DNA may be born without the participation of scientists in cases such microchimerism when present in the organism a quantity genetically foreign cells, which sometimes lead to deviations in embryonic development.
2. Bald chickens resistant to avian influenza
If you like chicken wings, this news certainly will please you: Israeli breeders brought breed chickens does not have fins that allows to reduce to no maintenance costs and save time for plucking. At the same time, it is said to have no feathers did not affect the taste, and avian influenza new chickens from birth are immune. Scientists have deduced "bald" chickens, experimenting with naked neck breed. They believe that these "birds" to grow more profitable than conventional layers.
However, tireless researchers do not forget that nature has endowed chicken feathers, not only for the sake of beauty, and for protection against insect pests, adverse weather conditions, as well as to protect the skin from the claws during mating.
3. Hypoallergenic dogs and cats
If you really want to get a dog, or a cat, but you prevent allergies, do not worry: the company is "Lifestyle Pets" offers customers hypoallergenic pets - cats and dogs with altered DNA. Unlike their natural counterparts, pets are not modified natural allergens (which, by the way, four cats and dogs - six), so they do not affect the well-being of the hosts.
"Improved" pets have one major drawback: at the price of $ 6950 few people can afford such a pleasure.
By the way, "Lifestyles Pets" are not pioneers on the market of genetically modified pets: Previously, scientists have invented another way to get rid of their pets from allergic properties. With the help of the so-called method of "genetic silence" the researchers were able to destroy the protein responsible for the production of allergens from cats, and if you do not want to expose your beloved pet this painful procedure, do not forget to take Allergy medications, when you play with him.
One of the most popular fish in the world, grown on an industrial scale, improved genetics to make tilapia more unpretentious, and make animals fatten faster weight - in today's fish and meat sector it is quite common practice. But there is one feature that distinguishes tilapia from other products of genetic engineering - scientists have made so that the light appears mostly males. The reason lies in the mechanism of protection of offspring, the present state of tilapia, - in case of danger the female hides the eggs and fry in his mouth, while stopping to eat, you do not accidentally eat children. This hunger strike can last up to a week, which negatively affects the growth of the fish, so it is more profitable to breed males, which is nothing to prevent fatten weight.
5. Golden seahorse
If you have money, but you are tired of boring gold gadgets, jewelry and luxury cars, look for unusual pet, which will emphasize the consistency of the owner and at the same time give him a lot of happy moments.
Vietnamese scientists have revealed the world of the seahorse, with mind though composed of pure gold. For his birth had to mix a certain amount of gold dust and protein contained in the jellyfish, and then add the resulting "cocktail" to the calf seahorses by the so-called "genetic firing", which is said to have in the future find wide application to change the DNA For example, in the treatment of diabetes. Doctors will be able to "shoot" through the cells, replacing the problematic regions of DNA healthy.
6. The camel as a pharmacy
Dubai Genetics went their own special way - they make changes to the genetic code of some animals to get the genetically modified milk, capable, according to preliminary estimates, to deal with certain diseases.
The basic material for the experiments are the camels, because the "ships of the desert" unpretentious food, resistant to disease and adapt easily to different climatic conditions.
7. The anti-malarial mosquitoes
Each year, about one million people were killed, one of the most difficult and dangerous in the world of disease - malaria. More than one generation of physicians beating on solving this problem, and one of the last arguments in the fight scientists believe the creation of genetically improved mosquitoes unable to spread malaria, and thus has an appropriate dominant gene. In other words, with conventional mosquito pairing and the modified progeny have appeared on the light will be blocked by the gene responsible for malaria transmission.
Of course, there is a risk response mutations that may neutralize the positive effect of the new gene, why, then, does not create a mechanism for the mosquitoes' genetic self-destruct "when the offspring will die, not even reached puberty, because now it's possible? The fact that the sharp decline in the number of mosquitoes inevitably affect the other links of the food chain, for example, may disappear a few rare species of bats, and insects for which, in particular, mosquitoes - one of the main components of the diet.
First farmed bull named Herman, he was born in Germany in 1990. Since then, science has considerably stepped forward, and now there are different breeds of cows that are resistant to rabies infection and did not even have horns to reduce the innate tendency to "bodlivosti".
Among the rocks, which were born by man - the famous Belgian Blue. Once, as a result of long-term experiments Breeders calf was born with a gene that suppresses the production of myostatin - a protein responsible for the suspension of muscle growth, so nagulivaniya meat process from the bull almost did not stop. The process of so-called doubling in muscle mass has allowed a new breed cows quickly gain popularity among farmers, in addition to an intensive weight nagulivaniya Belgian Blue cows are renowned for low-fat meat, dishes that attracts gourmands around the world.
9. Pork with spinach flavored
The Japanese raised pigs to help meat lovers improve their diet. Genetically modified breed of pigs called the creators of Popeye Pigs in honor of the famous character Disney cartoons - Captain Papaya, which feed mainly on spinach. Scientists have introduced one of the genes pig spinach which converts the saturated fat in pork, in a healthy and easily digestible unsaturated fats (linoleic acid).
Although research has not yet identified any complications in the use of genetically improved pork, implacable enemies meat eating this product is unlikely to enjoy - after all, you can just eat vegetables instead of inventing "vegetable meat."
10. Pets, glow in the dark
You have heard about the glowing rabbit? Ever since he was born in 2000, Genetics constantly experimenting with various animals, instilling in them the ability to emit light.
These experiments are carried out, not only to give people the opportunity to give each other funny dogs and cats, for example, the introduction of cats the gene responsible for the glow in the dark, and improves their resistance to immunodeficiency virus. The researchers created a luminous fish to track their migration and, in addition, the doctors say that experiments with fluorescent genes will help in developing treatments for Parkinson's disease and Alzheimer's.
Incidentally, one of their side goal of using a unique Japanese technology is to create extremely beautiful luminous silk via the introduction of appropriate gene-silkworm caterpillars.
