Nematodes, little soil-dwelling worms found on and off of every continent on Earth, are Dr. Bick's specialty.

线虫，生活在每个大陆上或周围土壤型蠕虫，是比克博士专业研究对象。

Nematodes, little soil-dwelling worms found on and off of every continent on Earth, are Dr. Bik's specialty.

线虫，生活在地球上每个大陆上土壤蠕虫，是比克博士专长。

Nematodes, of course, are much smaller than sandworms.

当然，线虫体型比沙虫要得多。

" Most nematodes, you can just barely see."

“大多数线虫几乎无法用肉眼看见。”

The team studied the mechanism of action in various species such as silkworms, nematodes, and fruit flies.

研究团队研究了在蚕、线虫和果蝇等多物作用机制。

And indeed, they found eight species of nematodes living there!

他们确实在那里发现了8线虫！

" They look like nematodes. You know, anything in the popular culture that has a relationship to worms, we follow."

“它们看起来很像线虫。流行文化与蠕虫有关任何东西，我们都会研究。”

Their charges are susceptible to intestinal nematode worms which cause them to waste away and can, in severe cases, kill them.

他们羊群容易受到肠道线虫影响，这些蠕虫会使它们日渐消瘦，在严重情况下，会令它们死亡。

So now we've got C. elegans the pupfish, C. elegans the tarantula, C. elegans the nematode, and C. elegans the turtle.

因此，现在我们 C. elegans 鳉鱼，C. elegans 狼蛛，C. elegans 线虫和 C. elegans 甲鱼。

Others may look familiar, but be stranger still, like nematodes.

其他一些可能看起来很熟悉，但仍然更陌生，比如线虫。

Not a snake nor an earthworm, nematodes are a creature all of their own.

It would be really interesting if we could get the nematodes to photosynthesize.

如果我们能让线虫进行光合作用，那将非常有趣。

For every single human on this planet, there exist 57 billion nematodes.

在这个地球上，每有一个人类，就存在570亿条线虫。

And indeed: they found eight species of nematodes living there!

事实上：他们发现那里生活着八线虫！

They discovered that down-regulating the expression of 7 genes significantly shortened the lifespan of nematodes, while down-regulating 3 genes extended their lifespan.

他们发现下调 7 个基因表达显著缩短了线虫寿命，而下调 3 个基因则延长了它们寿命。

Their charges are susceptible to intestinal nematode worms which cause them to waste away and can in severe cases.

它们羊群容易受到肠道线虫感染，导致羊群消瘦，严重时甚至会导致死亡。

But he'd found a recent study that suggested it might be possible in nematodes, these tiny freaky worms.

但他发现了一项最近研究， 表明这在线虫身上可能是可能，线虫就是那些微怪异蠕虫。

To solve that mystery, the researchers exposed 79 slugs to more than a million nematodes that had been tagged with a fluorescent marker.

为了揭开这个谜团，研究人员们将79只鼻涕虫放在用荧光标记过100万多只线虫环境。
