We are now to a major scientific breakthrough, building life from scratch. A biologist here in the US claimed to have created the first man made cell. He and his team researchers built this synthetic cell from human DNA inside their lab. The benefits really could be limitless. But then there are all these questions, you know, about ethics and moral issues as well.

現(xiàn)在科學(xué)有了大發(fā)現(xiàn),人類可以憑空創(chuàng)造生命。美國(guó)一名生物學(xué)家宣布其團(tuán)隊(duì)在實(shí)驗(yàn)室中合成了第一個(gè)具有人類DNA的人造細(xì)胞。這項(xiàng)科研結(jié)果帶來(lái)的效益將是無(wú)限的。但接下來(lái)問(wèn)題來(lái)了,在科技進(jìn)步的情況下,我們同樣需要考慮倫理道德。

And Michio Kaku is a theoretical physicist, physics professor and author of the book Physics of the Impossible. So, is this really a big deal? Why is it such a big deal?

Michio Kaku是一名理論物理學(xué)教授,著有《Physics of the Impossible》,那么,倫理在生命科學(xué)中真的重要嗎,為什么這么重要呢?

This is the proverbial game changer. It's like splitting the atom back in the 30s. In 10 years, splitting the atom change the political, economic, theological landscape. This is potentially on that scale.

眾所周知,這是一項(xiàng)顛覆傳統(tǒng)觀念的科研成果。就如30年前原子分裂一般,僅僅10年就從政治,經(jīng)濟(jì)和神學(xué)上改變了世界。如今這項(xiàng)科研成果很可能具有這項(xiàng)潛能。

So we are creating artificial life?

所以說(shuō),我們是在創(chuàng)造生命?

In some sense, yes, if you take a look at the cell, think aobut it is a cell phone. We've downloaded apps onto the cell phone all the time, so this time, we took a cell from a goat, and actually downloaded new DNA that we programed.

某種程度上說(shuō),是的。你可以把細(xì)胞想象成手機(jī)。我們下載應(yīng)用程序到手機(jī)上,就像我們將編輯好的程序置入山羊的細(xì)胞一樣。

So, a cell from a goat and with human DNA?

那就是說(shuō),這是一個(gè)取自山羊,但擁有人類DNA的細(xì)胞?

Well, different kinds of junk DNAs was put in, even James Joyce quotation from James Joyce. biography of Jay Robert, Robert Highbird. Also, this stuff was put in. The point was, that it was artificial, (got it ) and that's why this is so novel.

不同的DNA被分別置入細(xì)胞中,即使是喜劇大師James Joyce也會(huì)覺(jué)得這不可思議。Jay Robert和Robert Highbird也參與其中。重要的是這是人工合成的細(xì)胞,所以才會(huì)那么具有傳奇色彩。

So what can we do with an artificial cell? What can be some of the benefits?

那我們會(huì)對(duì)人工合成的細(xì)胞做什么呢?人類可以獲得什么好處呢?

We can tailor and make it to do certain things, like eat oil slicks. (No kidding). Exile is a very much interested in commercializing this technology. Already there are negotiations with talks. Also global warming. You can create bacteria that are specifically designed to eat up carbon dioxide.

我們可以調(diào)整,并且使它能夠做些有利人類的事,比如吞食水面浮油。(這不是在開(kāi)玩笑。)。Exile公司對(duì)于將這項(xiàng)技術(shù)商業(yè)化十分感興趣,并且已經(jīng)開(kāi)始洽談。但需要提醒的是,我們已經(jīng)創(chuàng)造出了以二氧化碳為食的細(xì)菌。

But this story reminds me of Jurrassic Park when all the dinosaurs got out and ran in the mark. I mean, there can be some unintended consequences, is that right?

但這類似于侏羅紀(jì)恐龍滅絕,我是說(shuō)這一定會(huì)造成一些意想不到的后果,對(duì)嗎?

That's right. You can not recall a life form, you can recall a bad Toyota, or General Motors car; You can recall a life form. And also killer bees, they were introduced in Brazil in the 1950s. Some Queen bees are escaped by accident. And these bees have now pushed down the honey bees out of the most of land of the America.

是的。你可以復(fù)活豐田,通用汽車,但你不能復(fù)活死去的生物。還有殺人蜂,它們是1950年被帶入到巴西。一些蜂王逃出,并驅(qū)逐美洲大陸上的工蜂。

And there were Tinker West?

還有Tinker West?

I know there were Tinker West, but it came Africa, deliberately introduced from Africa to Brazil (I see), to see whether we can get a better hybrid mix, but it was out of control. And now they are penetrating California, Texas, and Louisiana.

Tinker West來(lái)自非洲,為了配種被引進(jìn)到巴西,但之后的事情失去了控制。現(xiàn)在這些蜜蜂遍及加利福尼亞,達(dá)克薩斯和路易斯安那州。

So an example of unintended consequence is really quick. As a physicist, do you give thumbs up or thumbs down of this discovery?

意想不到的結(jié)果來(lái)得很快。那作為一名物理學(xué)家。您多人工合成細(xì)胞的事情有什么看法呢?

I think it this way, yuh, but it's between here and here.

我想這就是發(fā)展,不是好就是壞。

All right, we will see what will happen, just beginning now. So, I guess a lot of things could happen moving forward. Thank you very much, I appreciate your coming in and Joan, back up to you.

好的,我們將會(huì)持續(xù)關(guān)注事態(tài),這還僅僅是個(gè)開(kāi)始。因此,我猜有很多事情將會(huì)不斷向前發(fā)展。謝謝,感謝你來(lái)到這里,現(xiàn)在節(jié)目交回給Joan。
