And in one sample collected in 2015, the researchers found this one little rotifer.

霍普金：在 2015 年收集一个样本中，研究人员发现了这种小轮虫。

Just a reminder, rotifers have a simple brain and a simple nervous system.

提醒一下，轮虫有一个简单大脑和一个简单神经系统。

It means that a successful mutated line of rotifers will not be diluted by the genetic mixing caused by sexual congress.

这意味着一个成功轮虫突变系不会被有性繁殖引起基因混合所稀释。

The little creatures you see in the center of your screen, they are called rotifer.

你在屏幕中央看到小物，它们被称为轮虫。

It's a feeling of wonder like that first time I looked through a microscope as a kid staring at that rotifer.

Paul McEuen: So this little rotifer shows us something really amazing.

Paul McEuen：所以这个小轮虫向我们展示了一些非常惊人东西。

In fact, these little ladies reproduce asexually, laying eggs that hatch into the next generation of self-propagating rotifers.

霍普金：事实上，这些小雌性进行无性繁殖，产卵孵化出下一代自繁殖轮虫。

So, the previous record for frozen rotifers was a decade or so.

霍普金：所以，冷冻轮虫先前记录是十年左右。

Now, the fact that rotifers can spring to life after a thaw is not a total surprise.

现在，轮虫在解冻后能够重新活过来这一事实并不完全令人惊讶。

It's a microscopic worm called a rotifer that was brought back to life after spending about 25,000 years locked in the arctic permafrost.

这是一种被称为轮虫型蠕虫，在被困在北极永久冻土层中大约 25,000 年后复活了。

The next step is studying how rotifers can chill for millennia and still maintain their cellular integrity.

霍普金：下一步是研究轮虫如何在寒冷几千年后仍然保持其细胞完整性。

That's why we are going to study proteins that help rotifers to survive in those conditions.

Malavin：这就是为什么我们要研究有助于轮虫在这些条件下存蛋白质。

Entering a state of cryptobiosis allows even modern rotifers to survive seasonal changes in their local environment and more otherworldly assaults.

进入隐状态甚至可以让现代轮虫在当地环境季节性变化和更多来自其他世界攻击中存下来。

Rotifers are better—or at least more interesting—because they're multicellular animals, with a head and a body, that can eat, crawl around and make more rotifers.

霍普金：轮虫更好——或者至少更有趣——因为它们是多细胞动物，有头部和身体， 可以进食、爬行并制造更多轮虫。
