But gene drives also have some actual limitations.

不过基因驱动也有一些实际的限制。

But - a gene-altering strategy called gene drive changes that.

OK, remember how I said that gene drives originally had two problems?

前面我提过基因驱动有两大难题。

That's one that basically overwrites the change made by the first gene drive.

这样就可以覆盖 第一个基因驱动进行的改变。

In November 2018, signatories of a UN Convention on biodiversity noted uncertainties regarding engineered gene drives.

2018年十一月，联合国生物多样性公约的签署方指出了工程基因驱动的不确定性。

It’s hoped that gene drive can be tested in the wild within five to ten years.

希望在五到十年内基因驱动可以在野外进行测试。

It's hoped that gene drive can be tested in the wild within five to ten years.

我们希望，基因驱动能在未来5-10年里在野外环境中得到测试。

A gene drive is a term for genetic engineering that alters the probability of genes passed to offspring.

基因驱动是基因工程的一个术语，它改变基因传递给后代的可能性。

What's remarkable and powerful and frightening about gene drives is that that will no longer be true.

基因驱动的强大和可怕之处在于这种情况不再是理所当然的了。

Gene drive is something that scientists have known about for a long time.

基因驱动是科学家早就知道的事情。

The gene drive is, is a technical solution that allows a genetic qualification to be spread from few individuals to an entire population.

基因驱动是一种技术方案，让遗传条件从少数蚊子传到所有蚊子身上。

The only problem, gene drive has never been tested anywhere in Africa.

唯一的问题是，基因驱动从未在非洲任何地方进行过测试。

Now the question, how far are we from releasing gene drive?

现在的问题是，我们距离释放基因驱动还有多远？

Gene drive mosquitoes are already in the lab, and releasing them in the field is not going to take us more than 30 minutes.

基因驱动蚊子目前已在实验室中研制成功，将它们释放到野外只需 30 分钟。

Today, using the power of genetics, we can reduce or even eliminate mosquito-borne diseases, such as malaria, Zika, and even treat dengue with gene drives.

今天，利用遗传学的力量，我们可以减少甚至消除疟疾、寨卡病毒等蚊媒疾病，甚至可以通过基因驱动治疗登革热。

Gene drive holds a lot of promises, but it will not take us anywhere if we Africans aren't enabled to run it on our own.

基因驱动有很多前景，但如果我们非洲人不能自行运行它，它就无法带我们走向任何地方。

My colleagues and I at Target Malaria, and are working on something called gene drive: a way to control mosquito population and halt malaria transmission.

我和“目标疟疾”项目的同事正在研究一种叫做基因驱动的技术：一种控制蚊子数量和阻止疟疾传播的方法。

Such genes are said to drive, and so the name " gene drive." Our most promising strain affects female fertility by targeting a gene called doublesex.

这类基因被称为驱动基因，因此得名“基因驱动”。我们最有希望的菌株通过针对一种名为双性基因的基因来影响雌性生育能力。

Ladies and gentlemen, there is one more thing that needs to be done before gene drive can be released in the field in Africa.

女士们、先生们，在基因驱动技术在非洲实地推广之前，还有一件事要做。

They want to use a method of genetic modification called gene drive, which causes female insects to become infertile, but in a way that has proven immune to the evolution of resistance.

他们想使用一种被称为“基因驱动技术”的基因改造方法，这种方法可以让雌性昆虫不育，但以一种已经被证明对抗性进化免疫的方式。
