防弹皮肤问世：你也可以做超人
<p>荷兰研究人员最近用基因改良后的山羊奶和蜘蛛丝研制出了能够抵御子弹的人造皮肤。他们发现，经过基因改良的山羊奶含有跟蜘蛛丝相同的蛋白质。这种蛋白质从山羊奶中提取出来后便可将其拉伸进而编织成一种硬度相当于钢铁10倍的材料。这种材料可以在5周内跟人体皮肤融合，生出一层能够刀枪不入的“防弹皮肤”。据介绍，研究人员用.22口径长步枪子弹的重量和速度将该研究项目命名为“2.6<span word="g">g</span> 329<span word="m">m</span>/<span word="s">s</span>”。该研究的最终目的是用这种防弹皮肤代替人体皮肤中的角蛋白，从而造出真正的“防弹超人”。</p><p><span word="It">It</span> <span word="might">might</span> <span word="look">look</span> <span word="like">like</span> <span word="a">a</span> <span word="poorly">poorly</span> <span word="drawn">drawn</span> <span word="picture">picture</span> <span word="of">of</span> <span word="an">an</span> <span word="alien">alien</span>, <span word="but">but</span> <span word="this">this</span> <span word="is">is</span> <span word="actually">actually</span> <span word="one">one</span> <span word="of">of</span> <span word="the">the</span> <span word="most">most</span> <span word="advanced">advanced</span> <span word="types">types</span> <span word="of">of</span> <span word="skin">skin</span> <span word="ever">ever</span> <span word="made">made</span> - <span word="that">that</span> <span word="can">can</span> <span word="even">even</span> <span word="stop">stop</span> <span word="bullets">bullets</span>。</p><p><span word="It">It</span> <span word="might">might</span> <span word="look">look</span> <span word="like">like</span> <span word="a">a</span> <span word="poorly">poorly</span> <span word="drawn">drawn</span> <span word="picture">picture</span> <span word="of">of</span> <span word="an">an</span> <span word="alien">alien</span>, <span word="but">but</span> <span word="this">this</span> <span word="is">is</span> <span word="actually">actually</span> <span word="one">one</span> <span word="of">of</span> <span word="the">the</span> <span word="most">most</span> <span word="advanced">advanced</span> <span word="types">types</span> <span word="of">of</span> <span word="skin">skin</span> <span word="ever">ever</span> <span word="made">made</span> - <span word="that">that</span> <span word="can">can</span> <span word="even">even</span> <span word="stop">stop</span> <span word="bullets">bullets</span>。</p><p><span word="Researchers">Researchers</span> <span word="genetically">genetically</span> <span word="engineered">engineered</span> <span word="goats">goats</span> <span word="to">to</span> <span word="produce">produce</span> <span word="milk">milk</span> <span word="which">which</span> <span word="is">is</span> <span word="packed">packed</span> <span word="with">with</span> <span word="the">the</span> <span word="same">same</span> <span word="protein">protein</span> <span word="as">as</span> <span word="silk">silk</span> <span word="spiders">spiders</span>。</p><p>外星人？防弹皮肤！</p><p><span word="Once">Once</span> <span word="this">this</span> <span word="is">is</span> <span word="milked">milked</span> <span word="out">out</span> <span word="it">it</span> <span word="can">can</span> <span word="be">be</span> <span word="spun">spun</span> <span word="out">out</span> <span word="and">and</span> <span word="weaved">weaved</span> <span word="into">into</span> <span word="a">a</span> <span word="material">material</span> <span word="that">that</span> <span word="is">is</span> <span word="ten">ten</span> <span word="times">times</span> <span word="stronger">stronger</span> <span word="than">than</span> <span word="steel">steel</span>。</p><p><span word="The">The</span> <span word="fabric">fabric</span> <span word="can">can</span> <span word="then">then</span> <span word="be">be</span> <span word="blended">blended</span> <span word="with">with</span> <span word="human">human</span> <span word="skin">skin</span> <span word="to">to</span> <span word="make">make</span> <span word="what">what</span> <span word="the">the</span> <span word="scientists">scientists</span> <span word="hope">hope</span> <span word="will">will</span> <span word="be">be</span> <span word="tough">tough</span> <span word="enough">enough</span> <span word="to">to</span> <span word="stop">stop</span> <span word="even">even</span> <span word="a">a</span> <span word="bullet">bullet</span>。</p><p><span word="Dutch">Dutch</span> <span word="researcher">researcher</span> <span word="Jalila">Jalila</span> <span word="Essaidi">Essaidi</span> <span word="said">said</span> <span word="the">the</span> '<span word="spidersilk">spidersilk</span>' <span word="project">project</span> <span word="was">was</span> <span word="called">called</span> '2.6<span word="g">g</span> 329<span word="m">m</span>/<span word="s">s</span>' <span word="after">after</span> <span word="the">the</span> <span word="weight">weight</span> <span word="and">and</span> <span word="the">the</span> <span word="velocity">velocity</span> <span word="of">of</span> <span word="a">a</span> .22 <span word="calibre">calibre</span> <span word="long">long</span> <span word="rifle">rifle</span> <span word="bullet">bullet</span>。</p>
