寄生在我们脸上的螨虫

These Face Mites Really Grow on You | Deep Look

微观深望
[DEEP LOOK]
嘿 你脸上有东西
Hey, you’ve got something on your face.
呃 更像是生活在你的脸上
Well, more like living in your face.
看不见吗?
Can’t see them?
来吧 我们展示给你看
Here, we’ll show you.
研究人员只用了一点胶水
Researchers just use a little glue…
不要在家里尝试哦
Don’t try this at home.
当那层薄薄的皮层脱落时
When that thin layer of skin comes off,
会带下来一些微小的毛囊
it takes some tiny hair follicles
那些附在桃红色绒毛上 几乎看不见的毛囊
that barely-visible peach fuzz – with it.
这些毛囊看起来像一个微型的森林
Those follicles that came out look like a miniature forest.
当中的一些
And inside some of them…
就是面部螨虫
That’s a face mite!
旧金山加州科学院的昆虫学家Michelle Trautwein
Entomologist Michelle Trautwein at the California Academy of Sciences in San Francisco
研究方向就是我们脸上的这些“长期租客”
studies these long term tenants of ours.
它们有八支小步足
They’ve got eight little legs,
因为它们其实是蛛形纲动物
because they’re actually arachnids,
和蜱虫……
related to ticks
以及蜘蛛有关
and spiders.
没错 你身上现在就有很多这样的“偷渡者”
Yep, you almost certainly have dozens of these stowaways on you right now
然而你却完全不知道
and don’t even know it.
通常 你的免疫系统能够控制它们
Usually, Your immune system keeps them in check
但在极少情况下 螨虫数量激增会引发皮疹
But in rare cases, a population boom causes a red rash.
但别紧张
But don’t freak out.
真的!
Seriously!
事实上 它们并不总是一无是处
They’re actually not such bad houseguests.
你不是生来就带着螨虫的
You’re not born with them.
面部的螨虫是由父母传给婴儿的
Face mites are passed down from parent to baby.
它们一直藏在我们的毛囊里 紧挨着头发
They spend their days tucked right inside our hair follicles, next to the hair.
所有觉得舒适的地方
All cozy.
看到黄色的东西了吗?
See that yellow stuff?
那是皮脂
It’s sebum,
是由皮肤分泌的 可以防止皮肤干燥的物质
that greasy oil your skin makes to protect itself from drying out.
它也是螨虫的食物
That’s what face mites eat.
在你睡觉的时候 它们会爬到皮肤表面进行交配
When you’re asleep, they climb out to the surface and mate,
然后爬回你的毛孔产卵
before crawling back into your pores to lay their eggs.
太有趣了!
So, that’s fun!
但如果你想把它们都擦洗掉
But if you’re thinking about scrubbing them all off,
算了吧 你永远也摆脱不了它们
forget it, you’ll never get rid of all of them.
面部螨虫没有肛门
And here’s the weirdest part of all —
这是最奇怪的地方
face mites don’t have an anus.
它们只是不停地进食而从不排泄
They just eat and eat but never poop!
它们把我们广阔的皮肤视为自己的王国
They’ve made our vast landscape of skin into their own personal kingdom.
把它们当成一种自然的 甚至是健康的
Just think of them as a natural– maybe even healthy —
人类皮肤生态系统的一部分
part of your skin ecosystem.
现在你知道了 你再也不用感到孤独了
Now that you know, you never have to be lonely again.
哦 不仅如此 还有很多想和你出去“玩”的寄生虫
Oh yes, we’ve got even more things that want to hang out with you.
比如这些“会杂技”的头虱
Meet these acrobatic head lice.
一些可爱的水蛭?
Some cuddly leeches?
或是一些蜱虫?
Or maybe a few ticks?
如果《微观深望》让你有所收获
If Deep Look has grown on you,
到Patreon上给我们一些支持 好吗?
come over to Patreon and throw us some support, OK?
谢谢!
Thanks!
