Scene 1 5.6 mm caliber bullet with a mass of 2.6 g leaves the barrel. Velocity: 329 m / s Nearing the end. Gets! You're not wearing a bulletproof vest, so pierces the skin, muscles, sternum, pericardium and rips the heart muscle. Blood fills the pericardium, compressing the damaged heart, which - compressed - can not fill. Falling blood pressure. You lose consciousness. You die.
Scene 2 The same bullet. The same parameters. The bullet hits the skin i .. stops. The point of impact symbols and meanings is enormous bruise. SF? A computer game? Not at all. Arts. Biological art.
June 9, 2011, the Dutch institute for shooting forensic artist Jalila Essaidi in a special ballistic gel to mimic the human muscles, put your "baby" - a small piece of skin, which is bred in the laboratory. This is not "normal" skin, but pajęczo-human hybrid. Specifically pajęczo-human-silkworm. In a moment, symbols and meanings the child will be shot. Everything will be under the watchful eye of the cameras. A gunshot rings out. Sphere sweeps the skin of "muscle", but even so the skin is not draśnięta! Success, but only half - the projectile was half filled with dust (0.05 g instead of 0.1 g). Time for a second attempt. Standard, rushing at full speed ball skin no longer resisted. The bullet pierces her and gel. However, the experiment symbols and meanings was a success - because it was not a scientific experiment, but the artistic action. The skin went on show in the museum Naturalis in Leiden, and pictures for newspapers.
"I'm fascinated by biology and new materials, which gives us a biotechnology - explains Essaidi" Focusowi "origins of 2.6 g 329 m / s - As an artist, I want to get close as possible to the true beauty that we get from nature. For me, teaching is an important tool that allows you to achieve this. " The idea to grow pajęczo-human skin fell by reading an article in "Science", describing research professor. Randy Lewis of Utah State University. American scientist bred goats, in which the milk protein found in spider symbols and meanings silk.
Sounds like a mad scientist's fantasy, but to produce artificial spider symbols and meanings silk is the Holy Grail of biotechnology. In the future, this yarn can find a lot of applications - from materials superwytrzymałych the scaffold for culturing skin and ligaments. All thanks to its unique properties. Yarn tensile spider equal quality steel. It is more resistant to cracking (can absorb more energy and deform before the break) than Kevlar, and thus the material of which is made bulletproof vests.
Of course, it averages - in the world there are about 41 thousand. species of spiders, and each weaves several types of networks - insurance, hunted, locomotion, etc. The most powerful symbols and meanings of the tested threads produced by Caerostris DarwinI, symbols and meanings is 10 times more resistant to cracking than Kevlar!
The problem is that spider silk is not easy to obtain. Spiders symbols and meanings because, unlike silkworms - traditional "providers" yarn - can not be cultured ... They kill and eat until everyone (that has not been eaten) will take as much land as he needs.
This does not mean that the culture symbols and meanings was not attempted. In 1709, François-Xavier Bon de Saint-Hilaire has proved that spider symbols and meanings cocoons suitable for spinning. However, to produce 1 kg of material was needed for 1.3 million cocoons ... The venture proved so unprofitable.
Recently, weaving expert Simon Peers and Nicholas Godley symbols and meanings entrepreneur again took up the challenge. With the machine at the end of the nineteenth century, constructed by Fr Combue "wydoili" more than a million spiders in Madagascar. The resulting two unique symbols and meanings spider fabric: a scarf and shown in January at the Victoria & Albert Museum in London cape. The problem is that when the production of working ... More than 80 people for 8 years!
If spiders were so anti-social, the researchers decided to implant the gene responsible for the production of spider silk yarn more willing to cooperate organisms. Randy Lewis and his team have done first experience with goats, and then - from silkworms. "We placed a synthetic gene for the formation of proteins in the egg spider silk yarn together with control elements of a natural gene silk, spider so that the protein was produced in the same way as a normal silk protein" - translates "Focusowi" Dr. Lewis. symbols and meanings "A protein that was created, it was a mix of yarn spider game and leading" - he added. Interestingly, silk obtained from transgenic silkworms, only 4 per cent. consisted of a spider protein. Although symbols and meanings no match for natural production of spiders, and yes - he asserts Dr. Lewis - "was half the tougher and more flexible than ordinary silk." I received symbols and meanings this hybrid thread symbols and meanings Jalil.
"Silk from Utah was sent to Korea, where it namotano on the spool. Bornemann Etiketten company in Germany has done with the fabric they needed
