What headlines are we covering in today's News Digest?
今天的新闻文摘涵盖了哪些头条新闻？
Here is a quick look at our top stories.
以下是我们头条新闻的快速概览。
First, four astronauts complete a safe landing back on Earth after eight months aboard the space station.
首先，四名宇航员在空间站生活了八个月后，安全返回地球。

construction tool.
建筑工具还要响。
Stay tuned because our main news story begins right now.
请保持关注，因为我们的主新闻马上开始。
Our top story today comes from space exploration.
我们今天的头条新闻来自太空探索。
Four astronauts have safely returned to Earth after spending almost eight months living in orbit.
四名宇航员在轨道上生活了近八个月后，安全返回地球。
Eight months is a very long time to be away from home.
八个月对于离家在外来说是很长的一段时间。
Where did they land, Ethan?
他们在哪里着陆的，Ethan？
Their SpaceX capsule landed gently in the ocean.
他们的 SpaceX 太空舱平稳地降落在海洋中。
In space news, we call this kind of water landing a splashdown.
在太空新闻中，我们把这种水上着陆叫做溅落。
A splashdown?
溅落？
That sounds like jumping into a swimming pool.
听起来像是跳进了一个游泳池。
But I assume landing a spacecraft is much more complex.
但我猜测降落一艘宇宙飞船要复杂得多。
Indeed it is.
确实如此。
Big parachutes opened in the sky to slow down the capsule before it hit the water.
巨大的降落伞在空中打开，在太空舱触水前减速。
Special rescue boats were waiting nearby to help the crew out safely.
特种救援船只在附近等候，以帮助机组人员安全撤离。
Who was on this mission?
谁执行了这次任务？
Were all four astronauts from the same country?
这四名宇航员来自同一个国家吗？
No, it was an international team.
不，这是一个国际团队。
The crew included four astronauts, such as French astronaut Sophie Adano.
机组人员包括四名宇航员，例如法国宇航员索菲·阿达诺。
Together, they stayed aboard the International Space Station for 237 days.
他们一起在国际空间站呆了 237 天。
That is over seven months living in microgravity. Exactly.
那是在微重力环境下生活了七个多月。确实。
Microgravity means there is very little gravity.
微重力意味着只有很少的重力。
So objects and people float around inside the space station.
所以物体和人在空间站内四处漂浮。
Floating around sounds like fun for a day or two, but what happens to the human body after eight months?
四处漂浮一两天听起来很有趣，但八个月后人体会发生什么变化呢？
Without gravity pulling on your body, your muscles and bones can become weaker.
没有重力拉扯你的身体，你的肌肉和骨骼会变得更弱。
That is why astronauts must exercise every day in space.
这就是为什么宇航员在太空中必须每天锻炼。
I can see why.
我能理解为什么了。
When they finally return to Earth, even standing up must feel like lifting heavy weights.
当他们最终返回地球时，甚至连站起来都一定感觉像是在举重物。
It certainly does.
当然是的。
Doctors checked the astronauts right after they stepped out of the capsule.
医生们在宇航员刚踏出太空舱时就检查了他们。
Reports show that all four crew members are healthy and in good spirits.
报告显示，所有四名机组人员都很健康，精神状态良好。
That is wonderful news.
那真是精彩的消息。
I wonder what the first thing they wanted to eat was.
我想知道他们最想吃的第一样东西是什么。
Probably real, fresh food.
可能是真正的新鲜食物。
Many returning astronauts say they miss fresh fruit and crunchy vegetables the most, because space
许多返回的宇航员说他们最想念新鲜水果和脆生生的蔬菜，因为太空
food comes in sealed packages.
食物都是密封包装的。
I would definitely ask for a big, fresh salad and a comfortable bed that does not float around.
我肯定会要一份大份的新鲜沙拉，以及一张不会到处飘的舒适床铺。
Moving on to our second story, let us look even deeper into space.
接下来进入我们的第二个故事，让我们把目光投向太空更深处。
Astronomers using the James Webb Space Telescope have made another amazing discovery.
使用詹姆斯·韦布空间望远镜的天文学家们有了又一项惊人的发现。
The James Webb Space Telescope is always finding cool things in the night sky.
詹姆斯·韦布空间望远镜总能在夜空中发现酷炫的东西。
What did it find this time?
它这次发现了什么？
It detected the home galaxy of the farthest fast radio burst ever seen by humans.
它检测到了人类迄今见过的最远快速射电暴的宿主星系。
Hold on a second, Ethan.
等一下，伊森。
What is a fast radio burst?
什么是快速射电暴？
That sounds like a complicated science term.
这听起来像是一个复杂的科学术语。
Good question.
好问题。
A fast radio burst, or FRB, is a very short, sudden flash of energy from deep space.
快速射电暴（简称FRB）是来自深空的一种非常短暂、突发的能量闪光。
It lasts for only a fraction of a second.
它只持续短短的一小部分秒。
A fraction of a second?
秒的一小部分？
How can scientists even catch something that happens so fast?
科学家们怎么能捕捉到发生得这么快的东西呢？
It is difficult, but these bursts release an enormous amount of power.
这很难，但这些爆发会释放出巨大的能量。
In just a few milliseconds, an FRB can release as much energy as our sun produces in two whole days. Wow.
仅仅在几毫秒内，一个快速射电暴释放的能量就可以达到我们的太阳整整两天产生的能量。哇。
That is mind -blowing.
这真是令人震撼的。
So it is like a super bright cosmic flash, but in radio waves instead of visible light? Exactly.
所以它就像是一个超亮的宇宙闪光，只不过是以无线电波而不是可见光的形式出现？完全正确。
Think of it like someone taking a photo with a flash in a huge dark stadium.
想像一下，就像有人在一个巨大的黑暗体育场里用闪光灯拍照一样。
You see a quick light, but you need to figure out where in the stadium it came from.
你看到一道快速的光，但你需要弄清楚它是从体育场的哪个位置发出的。
And the Webb Telescope figured out where this cosmic flash came from. Yes.
而韦布望远镜弄清楚了这个宇宙闪光来自哪里。是的。
By looking closely with its powerful infrared cameras, Webb traced the signal back to an ancient galaxy.
通过用其强大的红外相机仔细观察，韦布将信号追溯到一个古老的星系。
This galaxy is so far away that its light traveled for billions of years to reach us.
这个星系如此遥远，它的光行了数十亿年才到达我们这里。
Billions of years?
数十亿年？
So when that flash of energy started, Earth was completely different.
所以当那道能量闪光开始时，地球完全不同。
That is right.
说得对。
Studying these distant signals helps scientists understand how galaxies formed in the early universe.
研究这些遥远的信号有助于科学家了解星系在早期宇宙中是如何形成的。
Science truly allows us to look back in time through light.
科学确实让我们能够通过光回溯时间。
That is so fascinating.
这太迷人了。
Now, let us bring our focus back to Earth and talk about our favorite pets.
现在，让我们把焦点带回地球，聊聊我们最喜欢的宠物。
If you have a pet dog, you might know that small dogs usually live longer than big dogs.
如果你有一只宠物狗，你可能知道小型犬通常比大型犬寿命更长。
Yes, I have noticed that.
是的，我注意到了这一点。
My friend has a tiny chihuahua that is 15 years old and still very energetic.
我朋友有一只15岁的小吉娃娃，仍然非常精力充沛。
But large dogs like Great Danes often live only 7 or 8 years.
但像大丹犬这样的大型犬经常只能活7或8年。
Why is that?
为什么会这样？
For a long time, scientists were not sure.
长久以来，科学家们并不确定。
But a new biological study has finally solved this mystery.
但一项新的生物学研究终于解开了这个谜团。
Oh, tell us.
哦，告诉我们吧。
What did the researchers find out?
研究人员们发现了什么？
The study shows that big dogs grow very fast when they are puppies.
研究表明，大狗在还是幼犬时生长非常快。
Because their bodies grow so quickly, their cells age much faster at a microscopic level.
因为它们的身体生长得太快，它们的细胞在微观层面上衰老得快得多。
At a microscopic level?
在微观层面上？
So their cells are working overtime to help them grow. Exactly.
所以它们的细胞在加班加点地帮助它们生长。完全正确。
Scientists looked at a biological process called epigenetics. Epigenetics.
科学家们研究了一个被称为表观遗传学的生物过程。表观遗传学。
That sounds like a tricky word for our listeners, Ethan.
对于我们的听众来说，这听起来像是一个棘手的词，伊森。
Can you explain it simply? Sure.
你能简单地解释一下吗？当然。
Think of your DNA as a giant recipe book for your body.
把你的DNA想象成你身体的巨型食谱书。
Epigenetics is like small sticky notes placed on the pages.
表观遗传学就像贴在书页上的小型便签。
These notes tell the body which recipes to read as you grow older.
随着你年龄的增长，这些便签会告诉身体阅读哪些配方。
Oh, that makes sense.
哦，这很有道理。
So in big dogs, those sticky notes change much faster because the body is growing so rapidly. Precisely.
所以在大狗身上，这些便签变化得快得多，因为身体正在迅速生长。没错。
Because their cells divide and build bone and muscle so fast, the cellular clock ticks faster in
因为它们的细胞分裂并迅速构建骨骼和肌肉，大狗体内的细胞时钟走得更快
large dogs.
大型犬。
That is a bit sad.
这有点伤感。
But understanding this process might help veterinarians keep large dogs healthier as they age.
但理解这个过程可能会帮助兽医让大型犬在变老时保持健康。
That is the goal.
这就是目标。
Scientists hope this research will lead to better diet plans and medical care to help big dogs live
科学家们希望这项研究能带来更好的饮食计划和医疗护理，帮助大狗生活
longer lives.
更长的寿命。
That would be fantastic for dog lovers everywhere.
这对世界各地的爱狗人士来说将是极好的。
For our final story today, we have some lighthearted news from the Amazon rainforest about a record
对于我们今天的最后一个故事，我们有一些来自亚马逊雨林关于一项打破记录的动物的轻松愉快的新闻
-breaking animal.
-打破记录的动物。
Ooh, I love animal stories.
噢，我喜欢动物故事。
Which creature are we talking about?
我们在谈论哪种生物？
We are talking about the white bell bird.
我们在谈论白钟鸟。
Scientists have confirmed that it is the loudest bird in the world. Really?
科学家已经证实它是世界上叫声最大的鸟。真的吗？
How loud can a small bird actually be?
一只小鸟到底能有多大声？
Believe it or not, the call of a white bell bird can reach 125 decibels.
信不信由你，白钟鸟的鸣叫声可以达到125分贝。
125 decibels?
125分贝？
To help our listeners picture that, how loud is 125 decibels compared to daily sounds?
为了帮助我们的听众想象一下，与日常生活声音相比，125分贝有多大声？
Well, a normal conversation is about 60 decibels.
嗯，正常的对话大约是60分贝。
A busy city street is around 80 decibels.
一个繁忙的城市街道大约是80分贝。
A jackhammer on a construction site is about 110 decibels.
建筑工地上的风镐大约是110分贝。
Wait, so this bird sings louder than a heavy jackhammer?
等等，所以这只鸟唱起歌来比重型风镐还要大声？
That is unbelievable!
这真是难以置信！
Yes, it is even louder than a loud music concert.
是的，它甚至比喧闹的音乐会还要吵。
If you stand close to this bird when it sings, the sound can hurt your ears.
如果你在它唱歌时站得很近，声音会伤害你的耳朵。
Why does a bird need to be so loud in the forest?
为什么鸟在森林里需要叫得这么大声？
Is it trying to scare away predators?
它是在试图吓跑捕食者吗？
Actually, male white bell birds use this super loud sound to attract female mates.
事实上，雄性白钟鸟用这种超级 大的声音来吸引雌性配偶。
To attract mates?
为了吸引配偶？
Imagine going on a date and having someone shout louder than a jackhammer right in your ear.
想象一下去约会时，有人在你的耳边大喊大叫，声音比风镐还要大。
That is almost what happens.
这几乎就是发生的事情。
The male bird turns toward the female and sings its loud song directly into her face.
雄鸟转向雌鸟，直接把响亮的歌声唱进她的脸部。
The female birds must have very tough ears.
雌鸟一定有非常强韧的耳朵。
Researchers found that the male bird has special, strong belly muscles to push out that much air.
研究人员发现，雄鸟有特殊、强壮的腹部肌肉来推挤出那么多的空气。
Nature always finds surprising ways to adapt.
大自然总能找到令人惊叹的方式来适应。
It certainly does.
它确实如此。
But if I ever visit the Amazon rainforest, I will bring earplugs, just in case.
但如果我有机会访问亚马逊雨林，我会带上耳塞，以防万一。
That brings us to the end of today's News Digest on Talkcast.
这将我们带到了今天Talkcast新闻摘要的尾声。
