Dutch Scientists Claim to Have Developed Bulletproof Skin

Dutch scientists claim to have developed bulletproof human skin, fabricated from spider silk and goat milk. Researcher Jalila Essaidi in collaboration with her team at the Forensic Genomics Consortium in the Netherlands have created a blend of spider silk, harvested from the milk of goats injected with spider-silk protein, and human skin cells. The developed material is believed at least 10 times stronger than steel.

The mission, '2.6g 329m/s' is aimed to make humans resistant to bullets through the replacement of keratin in our skin with spider's silk, making it much tougher as compared to normal skin.

“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”, she added.“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”.

In addition, Jalila Essaidi has expressed enthusiasm to test the limits of human endurance, and it starts by having milk spider-goats, innocent looking goats, designed for producing milk packed with the protein made in spider's silk.

由蛛丝蛋白制成的“防弹皮肤”问世有望使刀枪不入的超人走出科幻

据英国《每日邮报》报道，荷兰的科学家日前通过基因工程技术用蛛丝蛋白制成了一种高强度人造皮肤，这种“皮肤”甚至能够抵御子弹的射击而不被穿透。

实验中，研究人员首先通过转基因技术培育出了一种山羊，这种山羊能够生产出具有蛛丝蛋白的羊奶。在羊奶中加入一种特殊的溶剂后，就能提取到大量的蛛丝纤维。这种蛛丝纤维甚至比著名的凯夫拉尔纤维还结实，强度是钢的10倍。将这些纤维纺纱编织就能制成所需要的“超强布料”。

负责该实验的荷兰科学家杰勒·埃瑟迪说，他们的项目名为“2.6克 329米/秒”，就是取自点22口径步枪子弹的重量和速度，意在希望其研究成果能够抵御子弹的射击。

为了测试这种皮肤日后被植入人体的可能性，埃瑟迪的小组以一块手掌大小的蛛丝纤维“布料”为对象，用5周的时间在上面培育出了一层真正的皮肤。研究人员在美国视频网站YouTube上发布的一段视频显示，这种人造皮肤对子弹有一定的抵御作用。

埃瑟迪称，测试结果显示，虽然这种人造皮肤还有很多需要改进的地方，但他们把原先只存在于科幻小说中的东西变成了现实。她说：“其实我们可以抛开防弹背心，考虑得更长远一些——直接用蛛丝蛋白替换人体皮肤中的角蛋白。这样或许就能让我们的皮肤变得刀枪不入。”角蛋白广泛存在于脊椎动物皮肤、毛发和指甲等部位，是人类和其它动物体内的一种具有结缔和保护功能的纤维状蛋白质。……
