brains as we get older.
随着年龄增长而衰老的老大脑。
Plus, we have some quick updates on hot drinks and a new, cheaper cancer treatment.
此外，我们还为您带来关于热饮以及一种最新、更便宜的癌症疗法的简讯。
I am so ready for this, Zoe.
佐伊，我已经完全准备好听了这个了。
Let's start with our first story.
让我们从第一条报道开始。
If you love coffee, you will love this news.
如果您喜欢咖啡，您一定会喜欢这个新闻。
A new study suggests that caffeine can actually help ourselves age more slowly.
一项新研究表明，咖啡因实际上可以帮助我们的细胞更慢地衰老。
Wait, really?
等等，真的吗？
My morning cup of coffee is actually keeping me young?
我早上的那杯咖啡实际上能让我保持年轻？
That is the best news I have heard all week.
这是我这一周听说过最好的消息了。
But Zoe, how does caffeine do that?
但是佐伊，咖啡因是怎么做到那点的？
Well, the study shows that caffeine protects our cells from damage over time.
嗯，研究表明咖啡因可以保护我们的细胞免受随着时间推移而产生的损伤。
Our body is made of billions of tiny cells.
我们的身体由数十亿个微小的细胞组成。
As we get older, these cells get tired and do not work as well.
随着我们变老，这些细胞会变得疲倦，工作效率也不如从前。
Ah, so what is a simple way to think about this?
啊，那么理解这个问题的简单方式是什么呢？
I need a good picture in my head.
我需要在脑海中构思一个清晰的画面。
Imagine your cells are like tiny photocopy machines.
想象一下，你的细胞就像微型的复印机。
When you are young, the machine is brand new.
当你年轻时，这台机器是全新的。
It makes perfect copies of your DNA.
它能制作出你 DNA 的完美副本。
But as the machine gets older, the copies start to look blurry and weak.
但随着机器变老，复印件开始显得模糊和字迹微弱。
Right, I understand.
好的，我明白了。
So where does coffee come in?
那么咖啡是在哪里发挥作用的呢？
Caffeine is like a high -quality maintenance service for those machines.
咖啡因就像是为那些机器提供的高品质维护服务。
It helps them run smoothly for a longer time, so the copies stay sharp and clear.
它帮助它们更长时间地平稳运行 ，从而使复印件保持清晰明亮。
As a result, your cells age more slowly.
作为结果，你的细胞衰老得更慢。
That is a wonderful metaphor.
那是一个精彩的比喻。
But does this mean I should drink 10 cups of coffee today?
但这是否意味着我今天应该喝 10 杯咖啡？
No, absolutely not.
不，绝对不行。
In my opinion, moderation is key.
在我看来，适度是关键。
Doctors say that moderate coffee drinking is best.
医生表示，适度的咖啡饮用量是最好的。
That means about 3 to 4 cups a day.
那意味着每天大约 3 到 4 杯。
Too much caffeine can make you nervous and ruin your sleep.
摄入过多咖啡因会让你感到紧张不安并破坏你的睡眠。
Good point.
好观点。
I will stick to my regular amount.
我会坚持我常规的饮用量。
Still, it is nice to know my favorite morning drink has a secret power.
不过，能知道我最喜欢的早晨饮料拥有秘密力量还是很棒的。
Speaking of sleep, our next story is a warning about how we sleep.
说到睡眠，我们的下一个报道是关于我们如何睡眠的警告。
Researchers found that sleeping in low light can hurt your heart.
研究人员发现，在微光下入睡可能会伤害心脏。
Wait, what does low light mean?
等等，微光指的是什么？
Like having the television on or keeping a small lamp beside the bed? Exactly.
比如开着电视，或者在床头开着小台灯？一点没错。
Many people like to sleep with a bedside light on, or they leave the television playing in the background.
许多人喜欢开着床头灯睡觉，或者让电视在背景中播放。
However, the study says this is a bad idea.
然而，研究表明这是一个坏主意。
But why?
但这是为什么呢？
My eyes are closed, so how does the light affect me?
我的眼睛是闭着的，光线又是怎么影响我的呢？
Even when your eyes are closed, your brain can still sense the light.
即使在你闭着眼睛的时候，你的大脑仍然能够感知到光线。
As a result, your body doesn't fully relax.
结果，你的身体无法完全放松。
The researchers found that sleeping with even a little light increases your heart rate during the night. Wow.
研究人员发现，即使在微弱的光线下睡觉也会在夜间增加心率。哇。
So your heart has to work harder when you're supposed to be resting?
所以当你本该休息时，你的心脏却不得不更努力地工作？
Yes, exactly.
是的，完全正确。
It also affects how your body processes sugar, which can lead to a problem called insulin resistance.
它还会影响你身体代谢糖分的方式，这可能会导致被称为胰 岛素抵抗的问题。
Hold on.
等一下。
Insulin resistance sounds a bit complicated.
胰岛素抵抗听起来有点复杂。
Can you explain that simply for us? Sure.
你能为我们简单解释一下吗？当然可以。
Think of your body as a busy factory, and sugar is the fuel.
把你的身体想象成一座繁忙的工厂，而糖就是燃料。
Normally, your body has a special key, called insulin, to open the factory doors and use the fuel.
通常情况下，你的身体有一把叫做胰岛素的特殊钥匙，用来打开工厂的大门并使用燃料。
But when you have insulin resistance, the doors get rusty and the keys do not work well.
但当你产生胰岛素抵抗时，大门就会生锈，钥匙也无法很好地工作。
As a result, sugar builds up in your blood.
结果，糖分就会在你的血液中堆积起来。
Oh, I see.
哦，我明白了。
So sleeping with the light on makes our body's factory doors rusty.
所以开着灯睡觉会让咱们身体的工厂大门生锈。
What is a good analogy for the whole sleeping light issue?
对于整个开灯睡觉的问题，有什么好的类比吗？
Imagine your body is a car.
想象一下你的身体是一辆汽车。
When you sleep in a completely dark room, you turn the car engine off.
当你在一个完全黑暗的房间里睡觉时，你就熄火了汽车发动机。
The car rests fully.
汽车得到了充分的休息。
But if you sleep with a light on, it's like keeping the car engine running slowly all night.
但如果你开着灯睡觉，就相当于让汽车发动机整夜都在缓慢运转。
The engine never gets a real break.
发动机永远得不到真正的休息。
That makes perfect sense.
那完全说得通。
I am definitely turning off my television and bedside lamp tonight before I go to sleep.
今晚睡觉前我绝对会关掉电视和床头灯。
That is a very smart decision, Benjamin.
那是一个非常明智的决定，本杰明。
Now let's move on to our third major story, which is about protecting our brains.
现在让我们转到第三个重大新闻，是关于保护我们的大脑。
The World Health Organization, or WHO, has issued new guidelines.
世界卫生组织（WHO）发布了新的指南。
They say we can reduce our risk of dementia by 45%. 45 %?
他们表示我们可以将患痴呆症的风险降低45%。45%？
That is almost half.
那几乎是一半了。
But first, can you explain what dementia is? Yes.
但首先，你能解释一下什么是痴呆症吗？可以。
Dementia is a medical condition that affects the brain.
痴呆症是一种影响大脑的医学状况。
It makes it hard for people to remember things, think clearly, or make decisions as they grow older.
随着人们年龄的增长，它会让人很难记住事情、清晰思考或做出决定。
I see.
我明白了。
It is a very difficult condition for many families.
对于许多家庭来说，这是一项非常艰难的病况。
So how can we reduce the risk?
那么我们怎样才能降低这种风险呢？
A new study shows that two midlife habits are very important for protecting our brains.
一项新研究表明，两种中年习惯对保护我们的大脑非常重要。
These are regular physical exercise and continuous learning. Midlife?
它们是规律的体育锻炼和持续的学习。中年？
Does that mean when we are in our 40s and 50s?
那是不是指我们四五十岁的时候？
Yes, exactly.
是的，完全正确。
The choices we make during these middle years have a huge impact on our brain health later in life.
我们在中年时期做出的选择对以后的脑部健康有着巨大的影响。
So why do exercise and learning help our brains so much?
那么为什么锻炼和学习对我们的大脑帮助这么大呢？
Think of your brain like a muscle.
把你的大脑想象成一块肌肉。
If you do not use it, it gets weak over time.
如果你不用它，随着时间的推移，它就会变弱。
Physical exercise brings more oxygen to the brain, which keeps the brain cells healthy.
体育锻炼能为大脑带来更多的氧气，从而保持脑细胞健康。
Learning new things, like a language or an instrument, creates new connections in the brain.
学习新事物，比如一门语言或一种乐器，能在脑中建立新的连接。
Ah, so it is like going to the gym, but for your mind. Exactly.
啊，所以这就像去健身房锻炼， 不过锻炼的是大脑。确实如此。
If you only do the same easy things every day, your brain does not get a workout.
如果你每天只做同样简单的事情，你的大脑就得不到锻炼。
But when you challenge yourself, you build a stronger brain.
但是当你挑战自我时，你就能塑造更强大的大脑。
That is very encouraging.
那真是太令人鼓舞了。
It means we have a lot of control over our own brain health.
这意味着我们对自己的大脑健康有很大的控制权。
It is never too late to start a new hobby or go for a daily walk. Absolutely.
培养一个新的爱好或坚持每天散步，什么时候开始都不晚。完全正确。
Small daily habits can make a massive difference in the long run.
从长远来看，每天的小习惯可以带来巨大的改变。
I agree.
我同意。
Now, what are our quick updates for today, Zoe?
那么，佐伊，今天我们有哪些简短的最新动态呢？
Our first quick update is about hot drinks.
我们的第一条简讯是关于热饮品的。
A large study has found that drinking very hot beverages can triple your risk of cancer.
一项大型研究发现，饮用温度极高的饮料可能会使你患癌症的风险增加两倍。
Triple the risk?
风险翻三倍？
Oh my, I love my tea burning hot.
天哪，我喜欢喝滚烫的热茶。
Why is hot tea dangerous?
为什么热茶会很危险？
The extreme heat can damage the lining of your throat tube, which is called the esophagus.
极端的高温会损伤喉咙管道的内膜，也就是所谓的食道。
Over time, this constant damage can lead to esophageal cancer.
久而久之，这种持续的损伤可能会引发食道癌。
I see.
我明白了。
So the heat itself is the problem, not the drink?
所以问题出在热度本身，而不是饮料？
Yes, exactly.
是的，确切如此。
It does not matter if it is coffee, tea, or just hot water.
无论是咖啡、茶还是纯热水，这都不要紧。
If it is too hot, it can cause harm.
如果太热，就会造成伤害。
Well, that is an easy fix.
好吧，这很容易解决。
I will just wait a few minutes for my tea to cool down before I take a sip. Yes.
那我只要等几分钟让茶凉一下，然后再喝一小口就行了。是的。
Letting it cool down for just five minutes can keep your throat safe.
只需让它冷却五分钟，就能保护你的喉咙安全。
Good to know.
能知道这一点真好。
What is our second quick update, Zoe?
佐伊，我们的第二条快讯是什么？
It is some very exciting medical news from UCLA.
这是来自加州大学洛杉矶分校的一条令人兴奋的医学新闻。
Scientists have created a new cancer treatment using special cells called T -cells.
科学家利用被称为T细胞的特殊细胞开发出了一种新的癌症疗法。
This new treatment is much cheaper than older methods.
这种新疗法比传统的方法便宜得多。
Cheaper is always good.
更便宜总是好事。
How much cheaper are we talking about?
我们说的到底能便宜多少？
Older treatments could cost hundreds of thousands of dollars, but this new method could cost around
旧的疗法可能要花费数十万美元，但这种新方法的价格大约是
$5 ,000.
5,000美元。
$5 ,000?
5,000美元？
That is a huge drop.
那可真是巨大的降幅。
But Zoe, what are T -cells and how do they fight cancer?
但是佐伊，什么是T细胞？它们又是如何抗击癌症的呢？
T -cells are a type of white blood cell.
T细胞是一种白血球。
They are like the super soldiers of our immune system.
它们就像是我们免疫系统里的超级战士。
Normally, they find and destroy bad cells, like infections.
通常情况下，它们会寻找并消灭坏细胞，比如感染源。
But cancer cells are very clever, and they can hide from T -cells.
但癌细胞非常狡猾，它们能躲开T细胞。
So how does this new treatment help?
那么这种新疗法是如何起作用的呢？
Scientists teach the T -cells how to find and attack the cancer cells.
科学家教T细胞如何寻找并攻击癌细胞。
It's like giving the super soldiers a special map so they can find the hidden enemy.
这就像给超级战士一张特殊的地图，让他们能够找到隐藏的敌人。
This is a huge step forward for modern medicine.
这是现代医学向前迈出的巨大一步。
That is absolutely amazing.
那简直太令人惊叹了。
Medical science is moving so fast.
医学科学发展得如此之快。
It really is.
确实如此。
Well, that is all for our news today.
好的，以上就是我们今天的全部新闻。
But before we go, it's time for our daily quiz.

Listeners, here is today's question.
听众朋友们，今天是这个问题。
Why is sleeping with a bedside lamp or television on bad for your heart?
为什么开着床头灯或电视睡觉对心脏不好？
And what was the car analogy Zoe used to explain it?
佐伊用来解释这件事的汽车类比是什么来着？
Let's give everyone a moment to think.
让我们大家思考片刻。
Are you ready with your answer?
你准备好你的答案了吗？
The light keeps your brain active, so your heart rate increases instead of resting.
光线会让你的大脑保持活跃， 因此你的心率会增加而不是休息。
The analogy was that sleeping in a dark room is like turning a car engine off, while sleeping with
这个类比是：在黑暗的房间里睡觉就像关掉汽车发动机，而在
light is like keeping the engine running slowly all night. Perfect.
开着光睡觉就像让发动机整晚缓慢运转。太完美了。
You got it right again, Zoe.
佐伊，你又答对了。
