In all the billions of years that this planet has existed,only once did a cell survive to evolve into every living thing we have today.All life on Earth came from just one cell.So how are scientists going to create life in a lab.when nature only ever achieved this once?I've come to San Francisco to show you why the cell could become the most powerful tool on the planet.Building cells in the lab sounds like science fiction,but scientists can already alter the cells that nature has made.They can take cells that have evolved over billions of years and manipulate them in unbelievable ways.Dr Stephen del Cardayre leads a team of scientists who have started with a bacterial cell and re-engineered its inner workings.We've basically remodelled the cell.We've taken a naturally occurring bacteria,E.coli,and souped it up.We are taking this microbe,the chassis of this organism.It is analogous to building a monster truck.We start with a small truck,this bacteria,and we pull off the original wheels and put in some big wheels.Steve and his team have added new genetic components to the bacteria's ancient DNA.'When they take this cell,with its modified DNA,and feed it sugar,'the result is awesome.'I just want to get to it!I want to see them!I wanna find a good place on the slide.Stop there.'This round thing is a blob of pure diesel oil.'So these things here are the bacteria?You can see the rod shapes.Yeah,there's one.They're in the midst of,have just finished,converting renewable sugar to secreted,ultra-clean diesel.It's an oil product.'Feed sugar to these modified bacteria cells 'and they give you diesel oil.'That big blob is simply oil?That's our ultra-clean diesel product,a finished product fuel.We have to separate it,wash it a little bit and it's We have to separate it,wash it a little bit and it's ready to go.You're really blase about this,but that is completely nuts!You have got microbes producing diesel.We're really excited about it!We've been working really hard on thisThe microbes have been working harder!This is revolutionary Steve and his team have set up a test refinery where these manipulated bacteria are now producing just not just a few drops of oil,but gallons of it.And this is what you end up with,in this case,pure diesel.Just in case you think this is a hoax,watch this.Look at that!Diesel power!Sensational!Just a couple of days ago that was just bacteria.Now,it's running a diesel generator!That's the power of the cell.Diesel power!What's happening here is a glimpse of what cells would do for us in the future.As living machines,they have enormous powers.Up to now,we have only been able to manipulate naturally-occurring cells.But how much further could we go if we could actually create life,f we could build new cells from scratch?To do that,we'd have to solve a fundamental mystery -what gives a cell its spark of life?What turns lifeless chemicals into a living thing?

在所有的数十亿年,这颗行星存在,只有一次细胞存活进化成各样有血肉的活物,我们今天有.地球上的所有生命只是一个细胞来自…所以科学家们去创造生命时在实验室.只这一次的自然历史吗?我到旧金山来告诉你为什麽会成为细胞最强大的工具,在这个星球上细胞在实验室建设听起来像科幻小说,但科学家们已经能改变细胞,自然使他们可以把细胞的演化了数十亿年和操纵它们难以置信的方式斯蒂芬·德尔·Cardayre博士领导团队的科学家已经开始用一种细菌细胞和再造它的内部运作我们基本上重塑的细胞我们已经采取了天然细菌、大肠杆菌、souped吧我们正在服用这种微生物、底盘的有机体它类似于建立一个怪物卡车我们开始用一个小卡车,这种细菌,我们把原来的轮子,放入一些大人物斯蒂夫和他的队员们增添了新的基因成分细菌的古老的DNA.”时,他们把这细胞,其修改DNA,喂它糖,结果是awesome.',我只是想把它!我想看看他们!”我想找个好地方上把这一轮停就是一个纯粹的柴油oil.斑点.”于是这事吗.这是细菌你可以看到杆的形状.是的,那儿的人.他们当中,刚刚完成后,可再生的糖,ultra-clean分泌柴油它是一种“饲料糖油product.细菌的细胞,这些修改他们给你的那个大-柴油oil.仅仅是石油?这是我们的ultra-clean产品、成品柴油燃料我们不得不将它分开,洗它有点和它的我们必须分开了,洗它有点和它的准备去…你真地漠不关心,但那完全是神经病!你有微生物生产柴油我们很兴奋我们一直都很努力地工作上一直努力这样微生物这是革命斯蒂夫和他的球队已经建立了一个测试炼油厂这些操纵的细菌是现在不仅仅只生产几滴油,但加仑的它这是你最后,在这种情况下,柴油一旦你认为这是一场骗局,看这.看那!柴油动力!妙极了!几天前,只不过是细菌.现在,它的运行柴油发电机那是权力的细胞柴油动力!这里发生了什么是一个初步的了解细胞会为我们做将来作为生活,他们有巨大的权力机器…到目前为止,我们才能够操纵内细胞的.但是还有多远我们去创造生命.如果我们能实际上,我们可以建立新的细胞从零开始吗?要做到这点,我们必须解决的一个基本的神秘的-它提供了一种细胞的生命吗而毫无生气的化学物质进入一个活生生的吗?
