What is the big news today?
今天有什么重大新闻？
Today, we start with a major change to maps.
今天，我们首先来看地图的一个重大变革。
The United States is updating its official map coordinates, and your GPS location might shift by up
美国正在更新其官方地图坐标，您的GPS位置可能会移动多达
to four meters.
四米。
Four meters?
四米？
That is wild!
那真是太离谱了！
Next, we will meet an inspiring 14 -year -old student who used paper folding to design super strong
接下来，我们将认识一位鼓舞人心的14岁学生，他利用折纸设计出了超强
shelters for disaster areas.
用于灾区的避难所。
And we will head out into space to see how our moon was born.
我们还将飞向太空，看看我们的月球是如何诞生的。
New simulations show it might have formed in only five hours.
新的模拟表明，它可能仅在五小时内就形成了。
We also have quick updates on how tourist breathing is damaging beautiful caves, how Mars software
我们还带来了最新的简讯，关于游客的呼吸如何破坏美丽的洞穴，火星软件
is finding lost rock art on Earth, and how simple trees are going to be.
如何寻找地球上失落的岩画，以及简单的树木将会怎样。
It shows that great scientific ideas can come from anyone, anywhere.
这表明伟大的科学创意可以来自任何人、任何地方。
All you need is some paper, curiosity, and a lot of patience.
你所需要的只是一些纸、好奇心和足够的耐心。
I am definitely going to look at my paper airplanes differently from now on.
从现在开始，我肯定会以不同的眼光看待我的纸飞机了。
Now, let us look up at the night sky.
现在，让我们抬头看看夜空。
Scientists have a new theory about how our moon was born.
科学家们提出了关于月球如何诞生的新理论。
I thought we already knew how the moon formed.
我以为 我们已经知道月球是如何形成的了。
Didn't a giant rock hit the Earth and then the dust slowly came together over millions of years?
难道不是一颗巨石撞击了地球，然后尘埃在数百万年里慢慢聚集在一起吗？
That was the common theory for a long time.
长久以来这都是普遍的理论。
But scientists just ran some very powerful new computer simulations.
但科学家们刚刚运行了一些非常强大的新计算机模拟。
What did the simulation show?
模拟显示了什么？
They showed that the moon may have formed in just five hours.
它们显示月球可能在短短五小时内就形成了。
Five hours?
五小时？
That is shorter than a school day.
这比在学校上一天的课还要短。
How can a whole moon form so quickly?
一个完整的月球怎么能如此快速地形成？
The simulation shows that when the giant rock hit the young Earth, it threw a huge amount of hot
模拟显示，当那颗巨型岩石撞击年轻的地球时，它抛出了大量的炽热
rock into space.
岩石到太空之中。
Instead of turning into a dusty ring first, a large piece of the Earth's outer layer broke off
地球外层的一大块并没有先变成粉尘环，而是脱落了下来
almost completely intact.
几乎完全完整无损。
So the moon is basically a piece of the Earth that got knocked out and quickly became its own satellite? Yes!
所以月球基本上是被撞出去的地球碎片，并迅速成为了自己的卫星？是的！
The collision threw this big piece into a stable orbit within hours.
这次撞击在几小时内将这块巨大的碎片推入了一个稳定的轨道。
This explains why the rocks on the moon are chemically so similar to the rocks on Earth. Wow.
这就解释了为什么月球上的岩石在化学成分上与地球上的岩石如此相似。哇。
That is a very dramatic story.
那真是个非常戏剧性的故事。
It is like the Earth got into a giant space fight and lost a piece of itself, which became our
这就像地球卷入了一场巨型太空打斗，掉了一块肉，而那块肉变成了我们的
beautiful moon.
美丽的月球。
It is a very cool way to think about it.
这是想问题的一种非常绝妙的方式。
And it shows that space history can happen much faster than we think.
这表明航天历史的发展可能比我们想象的要快得多。
I love that.
我很喜欢这一点。
Space is always full of surprises.
太空总是充满了惊喜。
Now, let us go through our morning quick briefs.
现在，让我们来看看今天的早间简报。
First, let us talk about tourism.
首先，我们来谈谈旅游业。
Oh, I love traveling.
哦，我喜欢旅行。
Are we visiting a beautiful cave?
我们是要去参观一个美丽的洞穴吗？
Yes, but we must be careful.
是的，但我们必须小心。
A new study shows that the breadth of millions of tourists is slowly killing cave stalactites. Wait. Stalactites?
一项新研究表明，数百万游客的呼吸正在慢慢破坏洞穴钟乳石。等等，钟乳石？
Let me remember.
让我回忆一下。
Are those the rocks that grow down from the ceiling or up from the ground?
那些是从洞顶向下生长还是从地面向上生长的岩石？
Stalactites grow down from the ceiling.
钟乳石是从洞顶向下生长的。
They are shaped like icicles.
它们的形状像冰柱。
The rocks that grow up from the ground are called stalagmites. Right.
从地面向上生长的岩石被称为石笋。对。
So how does our breath damage them?
那么，我们的呼吸是如何损害它们的呢？
When millions of visitors enter a cave, they breathe out a lot of carbon dioxide and moisture.
当数以百万计的游客进入洞穴时，他们会呼出大量的二氧化碳和水分。
This changes the chemistry of the air inside the cave.
这改变了洞穴内空气的化学成分。
The humid air actually begins to corrode or slowly melt the delicate rocks.
潮湿的空气实际上开始腐蚀或慢慢融化这些脆弱的岩石。
That is sad.
这太令人难过了。
We are destroying ancient natural beauty just by looking at it and breathing.
仅仅通过观看和呼吸，我们就在破坏古老的自然之美。
Maybe we need to limit the number of visitors. Yes.
也许我们需要限制游客数量。是的。
Many famous caves are now looking for ways to protect these slow -growing rocks.
许多著名的洞穴现在都在寻找保护这些生长缓慢的岩石的方法。
I hope they find a solution.
我希望他们能找到解决办法。
What is our next quick brief?
我们的下一则速览简报是什么？
Next, NASA is using a photo trick designed for Mars to find ancient art on Earth.
接下来，美国国家航空航天局正在利用为火星设计的摄影技巧，来寻找地球上的古代艺术。
A Mars trick for Earth art?
用于地球艺术的火星技巧？
That sounds interesting.
那听起来很有趣。
NASA scientists created a special software to study satellite photos of Mars.
美国国家航空航天局的科学家开发了一款专用软件，用来研究火星的卫星照片。
It changes the colors in the photos so scientists can see different kinds of rocks and soil clearly.
它改变了照片中的颜色，使科学家能够清晰地看到不同类型的岩石和土壤。
How does that help us on Earth?
这在地球上对我们有什么帮助呢？
Archaeologists use the same software on photos of ancient cave paintings on Earth.
考古学家在地球古老洞穴壁画的照片上也使用了相同的软件。
Many of these paintings are thousands of years old and have faded so much that they are invisible to
其中许多画作已有数千年的历史，并且严重褪色，以至于对……来说是肉眼不可见的
the human eye.
人类的眼睛而言。
But when the software changes the colors, the ancient rock art suddenly appears bright and clear.
但是当软件改变颜色时，古老的岩画突然清晰地显现出来。
That is incredible.
这太难以置信了。
It is like wearing magic glasses to see ancient secrets.
这就像戴上了神奇的眼镜去探寻古代的秘密。
It is wonderful that space tools can help us learn about our own history.
太空工具能够帮助我们了解我们自己的历史，这真是太棒了。
It really is a great crossover of technology.
这确实是技术上的一次伟大跨界。
Finally, engineers at MIT have made simple water filters using slices of tree branches.
最后，麻省理工学院的工程师利用树枝切片制作出了简单的水过滤器。
Tree branches?
树枝？
How can wood clean water?
木头怎么能净化水呢？
Wood has natural microscopic channels, called xylem.
木材具有天然的微观通道，被称为木质部。
In a living tree, these channels carry water and nutrients from the roots to the leaves.
在活树中，这些通道将水和养分从根部输送到树叶。
They act like natural tiny straws.
它们的作用就像天然的微小吸管。
So the engineers used these natural straws to filter dirty water? Precisely.
所以工程师们用这些天然吸管来过滤脏水？一点没错。
They took small slices of tree branches and put them inside tubes.
他们切下细小的树枝切片，并将它们放入管子内部。
In lab tests, these wooden filters removed more than 99 % of bacteria and viruses from dirty water. 99 %?
在实验室测试中，这些木质过滤器清除了脏水中 99% 以上的细菌和病毒。99%？
That is as good as expensive plastic filters.
这和昂贵的塑料过滤器效果一样好。
Yes, and because it's made of simple wood, it is extremely cheap and biodegradable. Biodegradable?
是的，而且因为它是用普通木材制成的，所以极其便宜并且可生物降解。可生物降解？
That means it can naturally break down in the environment without causing pollution, right? Exactly.
这意味着它可以在环境中自然分解而不会造成污染，对吧？一点没错。
It just returns to nature.
它只是回归了大自然。
The team designed a simple gravity -fed filter that can clean one liter of water every hour.
该团队设计了一个简单的重力供水过滤器，每小时可以净化一升水。
That could save so many lives in poor areas without clean water.
这可以拯救缺少洁净水源的贫困地区的许多生命。
What a beautiful, natural invention.
多么美妙、自然的发明啊。
It really is.
确实如此。
And that brings us to the end of today's broadcast of Talkast.
这也意味着今天的 Talkast 广播节目接近尾声了。
We have talked about shifting maps, origami shelters, a fast -forming moon, endangered caves, ancient
我们讨论了变化的地图、折纸庇护所、快速形成的月球、濒危的洞穴以及古老的
rock art, and wooden water filters.
岩石艺术和木制的水过滤器。
We covered a lot of ground today.
我们今天涵盖了很多内容。
Now we have an exciting question for our listeners.
现在我们为听众准备了一个令人兴奋的问题。
If you could design a new object using origami folding, what would you make and why?
如果你可以运用折纸工艺设计一个新物品，你会制作什么？为什么？
Would you make a flat -packed desk, a strong camping tent, or maybe a cool piece of art?
你会做一个平板包装的书桌、一个坚固的露营帐篷，还是一件酷炫的艺术品？
