科学家研制出防弹皮肤

Bulletproof human skin made from spider silk and goat milk

It might look like a poorly drawn picture of an alien, but this is actually one of the most advanced types of skin ever made - that can even stop bullets.

Researchers genetically engineered goats to produce milk which is packed with the same protein as silk spiders.

Once this is milked out it can be spun out and weaved into a material that is ten times stronger than steel.

The fabric can then be blended with human skin to make what the scientists hope will be tough enough to stop even a bullet.

Dutch researcher Jalila Essaidi said the "spidersilk" project was called "2.6g 329m/s" after the weight and the velocity of a .22 calibre long rifle bullet.

She said the goal was to replace the keratin in our skin with the spider’s silk.

The first stage involves growing a layer of real skin around a sample of the bulletproof skin, which takes about five weeks.

A video posted by the researchers on YouTube shows a bullet then being fired into the mixture of the two.

Essaidi said that the project was making science fiction a reality, even if the tests results were not yet perfect.

She said that silk has a long history of using battle in combat and that Genghis Khan once issued all his horsemen with silk vests as an arrow hitting silk does not break, meaning you can tease it out.

“Imagine a spidersilk vest, capable of catching bullets, the modern day equivalent of Genghis Khan’s arrows,” she said.

Essaidi said:"Now, let’s take this one step further, imagine replacing keratin, the protein responsible for the toughness of the human skin, with this spidersilk protein. This is possible by adding the silk producing genes of a spider to the genes of a human: creating a bulletproof human."

Bullet proof vests have been around for decades but skin that can stop them has only been the preserve of science fiction.
 

据英国《每日邮报》8月16日报道,尽管看起来像一张粗糙的外星人的图片,这实际上却是迄今人类制造最先进的皮肤,它甚至可以防弹。
 

研究人员通过遗传工程创造的山羊可以产下一种特殊的羊奶。这种羊奶所含蛋白质与蜘蛛丝的蛋白质相同。
 

挤出这种羊奶,进行纺织,人们就能获得比钢牢固10倍的材料。
 

然后这种材料可以同人类皮肤混合,从而制成科学家所希望的足够坚硬、能够阻挡子弹的人类皮肤。
 

荷兰研究人员贾莉拉•埃萨迪说,这个“蛛丝”项目被称为“2.6克 329米/秒”,这是根据0.22英寸口径长步枪子弹的重量和速度命名的。
 

埃萨迪说,该项目的目标是用蜘蛛丝取代人类皮肤中的角蛋白。
 

第一阶段的实验需要在防弹皮肤的样本周围培养出一层真正的皮肤,这需要大概五周的时间。
 

研究人员在YouTube上公布的视频显示,他们之后将子弹射向这种混合性的皮肤。
 

埃萨迪说,这个项目把科幻小说变成了现实,尽管测试结果尚不完美。
 

她说,历史上丝织品曾长期用于作战,成吉思汗曾经给他的骑兵发放丝质马甲,这种马甲在箭的攻击下不会破裂。
 

她说:“想象一下可以挡住子弹的蜘蛛丝背心,子弹就相当于成吉思汗的箭。”
 

 

埃萨迪说:“现在让我们更进一步,想象一下用蛛丝蛋白质代替人类角蛋白。角蛋白是使人类皮肤坚硬的一种蛋白质。这可以通过在人类基因组中添加蜘蛛的造丝基因,从而创造出‘防弹人’”。
 

 

防弹背心已经存在了数十年,但是防弹皮肤还仅存于科幻小说中。
