And of course, snap traps, like our friend the Venus flytrap.

当然，还有捕兽夹式陷阱，比如我们的朋友捕蝇草。

Believe it or not, the Venus flytrap is on the verge of becoming an endangered species.

信不信由你，捕蝇草现在濒临灭绝。

Sometimes those responses are recognizable and action-packed — like a Venus flytrap snapping shut on a bug.

有时，这些反应是可识别的，而且充满了动感——就像捕蝇草捕捉昆虫一样。

For example, among the species at risk of extinction is the Venus flytrap, a plant that " eats" insects.

例如，在濒临灭绝的物种中，有一种叫捕蝇草，它是一种以昆虫为食的植物。

It's called a flytrap because, as you probably know, it's famous for trapping flies in its toothy leaves.

它被称为捕蝇草，因为你可能知道这种植物以把苍蝇困在它的齿状叶子里而闻名。

The Venus flytrap uses a modified version of that jasmonic acid signal.

维纳斯捕蝇草使用茉莉酸信号的改良版本。

He wants you to shut that flytrap you got hanging down.

他是说让长在你身上的捕蝇器收声。

So here we are seeing the flytrap actually doing a computation.

所以在这里我们看到捕蝇草实际上在进行计算。

So, as unique as they look, the Venus flytrap’s claws and chemistry are evolutionarily repurposed tools.

因此，尽管它们看起来很独特，但维纳斯捕蝇草的爪子和化学物质是经过进化改变用途的工具。

And to understand why that is, we need to know a little bit more about the behavior of the flytrap.

为了理解为什么会这样，我们需要更多地了解捕蝇草的行为。

I'm going to go ahead and trigger this mimosa right now by touching on the hairs of the Venus flytrap.

我现在要通过触摸金星捕蝇器的头发来触发这个含羞草。

The Venus flytrap is a strange plant that only grows naturally in the coastal bogs of North and South Carolina in the United States.

捕蝇草是一种奇怪的植物，只在美国南、北卡罗来纳州的沿海沼泽中生长。

There are also snap traps which are active, using rapid modified leaf movements, like  those of a Venus flytrap, to snag prey.

还有一些活跃的捕捉器，利用快速修改的叶子运动，如维纳斯捕蝇器， 捕捉猎物。

Instead of releasing compounds to make itself taste bad, jasmonic acid stimulates the flytrap to unleash a cocktail of killer digestive enzymes into its green stomach.

茉莉酸并没有释放化合物让自己变味，而是刺激捕蝇草在它绿色的胃里释放出一种致命的消化酶混合物。

So while they may seem pesky, thorny or even downright mean, Venus flytraps are our friends, and we should make an effort to keep them safe, at least in the real world.

虽然它们可能看起来很烦人，身上有刺，甚至用刻薄来形容也不为过，但捕蝇草其实是我们的好朋友，我们应该努力保护它们的安全，至少在现实世界中。

For example, a key genetic change in the  evolution of carnivory took place in a common ancestor of Venus flytraps and sundews  that lived about 60 million years ago.

例如，食肉动物进化过程中的一个关键遗传变化发生在生活在大约 6000 万年前的维纳斯捕蝇草和茅膏菜的共同祖先身上。

When these nucleotides get into the flytrap alongside glutamate, they stabilize its structure, making it close even harder and more securely, so an even stronger umami signal goes to your brain.

当这些核苷酸与谷氨酸盐一起进入捕蝇草受体时，它们会稳定其结构，使其更牢固、更安全地闭合，从而向你的大脑发出更强的鲜味信号。

The glands inside of the trap, though, expressed genes much more similar to the Venus flytrap’s roots -- which actually makes sense, since both parts of the plant absorb nutrients.

不过，捕蝇草内部的腺体表达的基因与维纳斯捕蝇草的根更相似— — 这实际上是有道理的， 因为植物的两个部分都吸收养分。

The magic starts when glutamate hits a part of the umami receptor on your tongue called the Venus flytrap domain, so named because it's shaped like a Venus flytrap, with two lobes around a hinge.

当谷氨酸盐击中你舌头上称为捕蝇草域的一部分鲜味受体时，魔法就开始了，之所以如此命名是因为它的形状像一个捕蝇草，在铰链周围有两个叶瓣。

To be honest, I had to think about it a little before I said yes because I was taking on a topic that was basically a Venus flytrap of everything that makes people mad.

老实说，在我说是之前我不得不考虑一下， 因为我正在讨论一个基本上是一切让人发疯的维纳斯捕蝇草的话题。
