The goat goat milk produced by a genetically modified goat produced by the scientists contains the same protein as the spider silk. The firmness of the fabric made of "goat spider silk" is four times that of the Kevlar fiber used in the bulletproof vest. In the lab, scientists mixed goat's silk with bio-engineered human skin to obtain artificial skin with bulletproof capabilities.

The firmness of a web made of spider silk is four times that of Kevlar.

Bioengineered skin is capable of withstanding bullet bombardment at half-speed firing, but is unable to withstand bullets flying at full speed.

The skin is made of layered spider silk and artificial skin grown in the laboratory.

"New Scientist" magazine reported that: "Bioengineered skin can withstand bullet bombardment at half speed, but its impact resistance is extremely limited. When the bullet reaches a full speed of 329 meters per second, the bullet penetrates the skin." Dutch researcher Galila. Isadi said that the spider silk research project is called "2.6 grams per second 329 meters," and is named after the weight and speed of a 22-caliber rifle bullet. The goal of this study was to replace the keratin in human skin with spider silk protein.

The spider silk used in the study was produced in Utah, USA, then spun in Korea, and then woven into fabric in Germany. The last step is to have a layer of real skin around the bulletproof skin. The whole process lasted about 5 weeks. Isadier pointed out that this research made science fiction a reality. Spider silk has a long history of warfare. Genghis Khan had used a silk vest for all cavalry soldiers against the arrows shot by the enemy.

She said: "Imagine a bullet-proof vest made of spider silk that can withstand the impact of bullets and capture the bullets - bullets are equivalent to the modern version of the arrow of the era of Genghis Khan. Now, let us go further, Why only make bulletproof vests? Imagine replacing the keratin in the skin with spider silk protein, which is related to the toughness of the skin."

Isadi said: "The possibility of implanting spider silk genes into the human genome is also possible. This will create bulletproof people. Sounds like science fiction? Maybe, but we think that this idea of ​​creating superhumans can become The reality is that the spider silk with anti-elastic properties is combined with artificially cultivated skin." Bulletproof vests have been around for decades, but bullet-proof skin has always existed in science fiction. The most famous example is Superman. Invincible super hero.
