荷蘭研究人員最近用基因改良后的山羊奶和蜘蛛絲研制出了能夠抵御子彈的人造皮膚。他們發現，經過基因改良的山羊奶含有跟蜘蛛絲相同的蛋白質。這種蛋白質從山羊奶中提取出來后便可將其拉伸進而編織成一種硬度相當于鋼鐵10倍的材料。這種材料可以在5周內跟人體皮膚融合，生出一層能夠刀槍不入的“防彈皮膚”。據介紹，研究人員用.22口徑長步槍子彈的重量和速度將該研究項目命名為“2.6g 329m/s”。該研究的最終目的是用這種防彈皮膚代替人體皮膚中的角蛋白，從而造出真正的“防彈超人”。

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.

Working with the Forensic Genomics Consortium in the Netherlands, 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.

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

‘Now, let’s take this one step further, why bother with a vest: 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 gnome of a human: creating a bulletproof human.

‘Science-fiction? Maybe, but we can get a feeling of what this transhumanistic idea would be like by letting a bulletproof matrix of spidersilk merge with an in vitro human skin.’

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

The most famous example is Superman, or the Man of Steel - bullets simply ricochet off of him.
