现在，Zoe，今天我们的节目里有哪些令人兴奋的健康与生活方式动态呢？
We have an essential lineup for you.
我们为您准备了一份至关重要的节目单。
We start with a sobering health alert.
我们首先带来一条令人警醒的健康预警。
Alcohol -linked cancer deaths have doubled in recent decades, challenging what we think we know about
在最近几十年来，与酒精相关的癌症死亡人数翻了一番，挑战着我们自认为了解的
moderate drinking.
适度饮酒。
That is definitely something we need to unpack.
这绝对是我们有必要深入剖析的内容。
Following that, we will look at how U .S.
随后，我们将探讨美国
scientists are turning to an unexpected animal ally, chickens, to protect us from a rise in mosquito

声音如何就大脑健康向你发出预警。
And to wrap it all up, we have a heartwarming story about a very special box turtle named Pedro, who
最后，我们有一个暖心的故事，关于一只名叫 Pedro 的非常特别的箱龟，它
got a second chance at moving around thanks to some creative veterinarians and Lego wheels.
多亏了一些富有创意的兽医和乐高轮子，它获得了重新走动的第二次机会。
I can't wait for that one.
我都等不及想听那个故事了。
Let's jump right into our lead story.
让我们直接进入我们的头条新闻。
A series of long -term medical studies have revealed a worrying trend.
一系列长期医学研究揭示了一个令人担忧的趋势。
Cancer deaths directly linked to alcohol consumption have doubled over the last few decades.
与酒精摄入直接相关的癌症死亡人数在过去几十年中翻了一番。
What's even more surprising is that even light drinking can significantly raise cancer risk,
更令人吃惊的是，即使是轻度饮酒也会显著增加患癌风险，
especially for adults over 50.
尤其是对于 50 岁以上的成年人。
Wow, Zoe, hold on. Doubled?
哇，Zoe，等一下。翻倍了？
That's a massive jump.
那可是个巨大的跨越。
We often hear stories about how a single glass of red wine is good for the heart.
我们经常听到关于单单一杯红酒 对心脏有好处的说法。
Are doctors now saying that even one drink a day is dangerous?
医生们现在是说每天即使喝一杯酒也是危险的吗？
Yes, Lucas.
是的，卢卡斯。
The scientific consensus is shifting.
科学 界的共识正在发生转变。
Research shows that alcohol is a direct carcinogen.
研究表明，酒精是一种直接的致癌物。
When our bodies break down alcohol, they turn it into a chemical compound called acetylaldehyde.
当我们的身体分解酒精时，会将其转化为一种名为乙醛的化学化合物。
This chemical can damage our cell DNA and prevent our bodies from repairing that damage, which can
这种化学物质会损坏我们的细胞 DNA，并阻止我们的身体修复这种损伤，而这可能
lead to tumors in the liver, breast, colon, and esophagus. Acetylaldehyde.
导致肝脏、乳腺、结肠和食道出现肿瘤。乙醛。
That is quite a mouthful for our vocabulary list.
对于我们的词汇表来说，这还真是个拗口的词。
Let's write that down.
让我们把它记下来。
A carcinogen, which is any substance that can cause cancer.
致癌物，即任何能够导致癌症的物质。
But Zoe, how does this affect our daily life?
但是 Zoe，这会如何影响我们的日常生活呢？
Is there a safe limit?
存在安全的限度吗？
Honestly, health experts now suggest that the safest level of drinking is none at all.
坦白说，健康专家现在建议最安全的饮酒量是完全不喝。
But if you do choose to drink, moderation is key, and being aware of the risk is crucial.
但如果你确实选择饮酒，适度是关键，意识到风险是至关重要的。
Think of alcohol like exposure to strong sunlight.
把饮酒想象成暴露在强烈的阳光下。
A little bit of sun gives you vitamin D, but too much burns your skin and increases your skin cancer risk.
少量的阳光能为你提供维生素D，但过量会晒伤皮肤并增加患皮肤癌的风险。
We need to treat alcohol with the same level of caution.
我们需要以同样的谨慎态度对待酒精。
That is an excellent analogy, Zoe.
这是一个极好的类比，佐伊。
We don't need to panic, but we definitely need to be mindful of how much we consume.
我们不必恐慌，但我们绝对需要留心我们的摄入量。
Speaking of protecting our health from external risks, our next story takes us outdoors, where
说到保护我们的健康免受外部风险的侵害，我们的下一个故事将带我们走出门外，在那里
mosquito -borne illnesses like West Nile virus are on the rise across the United States, but
像西尼罗河病毒这样由蚊子传播的疾病在美国各地呈上升趋势，但是
scientists are fighting back with an unusual weapon, chickens.
科学家们正在用一种不寻常的武器进行反击，那就是母鸡。
Yes, this is one of the most fascinating public health strategies.
是的，这是最引人入胜的公共卫生策略之一。
Health departments are deploying what they call sentinel chickens to keep communities safe.
卫生部门正在部署他们所说的“哨兵鸡”来确保社区安全。
Wait, sentinel chickens?
等等，哨兵鸡？
Sentinel is a word that means a soldier or guard whose job is to stand and keep watch, right?
Sentinel（哨兵）这个词的意思是站岗守望的士兵或警卫，对吧？
Are these chickens wearing tiny guard uniforms and chasing mosquitoes?
这些鸡穿着微型警卫制服追赶蚊子吗？
Not quite, Lucas, though that would be a hilarious sight.
不完全是，卢卡斯，虽然那将是一个极滑稽的景象。
Sentinel chickens are regular chickens, housed in coops and areas with high mosquito activity.
哨兵鸡就是普通母鸡，安置在鸡舍以及蚊子活动频繁的区域。
Because chickens don't get sick from the West Nile virus, but their immune systems still produce
因为鸡不会因西尼罗河病毒生病，但它们的免疫系统仍然会产生
antibodies when they are bitten by infected mosquitoes, scientists can test their blood regularly.
当被感染的蚊子叮咬时产生的抗体，科学家可以定期检测它们的血液。
If the chickens test positive, it means the virus is active in that specific neighborhood, giving
如果这些鸡检测呈阳性，意味着病毒在该特定社区内处于活跃状态，从而
local officials a head start to spray for mosquitoes before humans start getting sick.
让当地官员在人类开始生病之前抢先喷洒杀蚊药。
Aha, so they're like a biological radar system.
阿哈，所以它们就像是一个生物雷达系统。
They don't get hurt, but they sound the alarm for us.
它们不会受伤，但它们为我们拉响了警报。
That is incredibly clever. Exactly.
那真是难以置信地聪明。完全正确。
It's a fantastic example of using nature to protect human health.
这是利用自然保护人类健康的绝妙范例。
It acts just like a smoke alarm in your house.
它的作用就像你家里的烟雾报警器。
The alarm detects the smoke before the fire spreads to the rest of the building, allowing you to put
报警器在火势蔓延到建筑物其他部分之前检测到烟雾，使你能够把它
it out safely.
安全地扑灭。
I love that.
我喜欢那个。
Shout out to the brave sentinel chickens keeping our neighborhood safe.
向保持我们社区安全的勇敢哨兵鸡致敬。
Now, let us move from the outdoors into the bedroom.
现在，让我们从户外转移到卧室。
Zoe, you mentioned a common sleep mistake that might be damaging our hearts.
佐伊，你提到了一个可能正在损害我们心脏的常见睡眠错误。
What is it?
那是什么？
It is sleeping with too much light in the room.
那就是在光线过强的房间里睡觉。
A new study has found that even a tiny amount of light exposure during sleep, like a glowing
一项新研究发现，即使是睡眠期间微量的光线暴露，比如发光的
television screen, a bright streetlight outside, or even a bedside lamp, can significantly increase
电视屏幕、外面明亮的路灯，甚至是床头灯，都会显著增加
heart rate and impair insulin regulation the next morning.
心率并在次日清晨损害胰岛素调节功能。
But Zoe, when we sleep, our eyes are closed.
但是佐伊，当我们睡觉时，我们的眼睛是闭着的。
How can a little bit of light through our eyelids affect our heart?
透过我们眼睑的一点点光线怎么会影响我们的心脏呢？
It is not like we are actively watching the television.
这又不像我们是在主动看电视。
That is the tricky part.
这正是棘手的地方。
Our brain is highly sensitive to light, even when our eyes are shut.
我们的脑部对光线高度敏感，即使在我们的眼睛闭上时也是如此。
When light hits our eyelids, it sends a signal to our brain that it is daytime.
当光线照射到我们的眼睑上时，它会向我们的脑部发送一个信号，提示现在是白天。
This prevents our nervous system from fully relaxing.
这会阻止我们的神经系统完全放松。
Normally, your heart rate drops at night to rest and recover.
通常，你的心率在夜间会下降，以获得休息和恢复。
But with light in the room, your heart rate stays elevated.
但在房间有光线的情况下，你的心率会保持升高状态。
Oh, I see.
哦，我明白了。
It's like having a sleeping manager at a company.
这就像公司里有一个在睡觉的经理。
Even if the manager is resting in their office, if people keep knocking on the door or shining
即使经理正在办公室休息，如果有人不断敲门或照射
lights through the window, the manager never gets a deep, peaceful rest.
透过窗户的光线，管理者永远无法获得深度而宁静的休息。
They are always on high alert.
他们时刻保持着高度警惕。
Perfect metaphor, Lucas.
完美的比喻，卢卡斯。
Your heart is that manager.
你的心脏就是那个管理者。
Over time, that constant low -level stress can lead to heart disease and high blood pressure.
随着时间的推移，那种持续的低度压力可能会导致心脏病和高血压。
The easy fix?
简单的解决方法是什么？
Use blackout curtains, turn off the TV, and if you cannot get your room completely dark, wear a
使用遮光窗帘，关掉电视；如果无法让房间彻底变黑，就戴上
simple, comfortable sleep mask.
一个简单而舒适的眼罩。
A sleep mask is a very cheap and cozy solution.
睡眠眼罩是一个非常便宜且舒适的解决方案。
I am definitely keeping my bedroom pitch black tonight.
今晚我绝对会让卧室保持漆黑。
Now, Zoe, let us dive into our quick news briefs.
现在，佐伊，让我们深入了解一下今天的新闻简报。
What is this exciting news about berries and fat burning?
关于浆果和脂肪燃烧的这个令人兴奋的新闻是什么？
Scientists have discovered a natural compound in grapes and blueberries that actually unlocks a fat
科学家在葡萄和蓝莓中发现了一种天然化合物，实际上能够开启脂肪
burning process inside our muscle cells.
肌肉细胞内部的燃烧过程。
It helps reduce abnormal fat buildup in the body, which could be a game changer for metabolic health
它有助于减少体内异常的脂肪堆积，这对于新陈代谢健康来说可能是一个改变游戏规则的突破
and weight management.
和体重管理。
That sounds delicious.
那听起来很美味。
So eating berries can actually tell our muscles to burn more fat?
所以吃浆果实际上可以告诉我们的肌肉去燃烧更多脂肪？
Sign me up for a fruit salad. Absolutely.
算我一份水果沙拉。当然。
It's a great excuse to add fruit to your breakfast.
这是往早餐里添加水果的绝佳理 由。
Our second brief is about how our voice might hold clues to our brain health.
我们的第二份简报是关于我们的声音如何可能包含大脑健康的线索。
Researchers found that subtle changes in a person's voice, such as a slower speaking rate, longer
研究人员发现，一个人声音中细微的变化，比如说话速度变慢、更长
pauses, or a slight change in pitch, can be early signs of cognitive decline or dementia years
停顿，或者音调的微小变化，可能是数年前认知下降或痴呆症的早期征兆
before memory problems appear. Wow.
在记忆问题出现之前。哇。
So our voice acts like an early warning signal too?
所以我们的声音也扮演着早期预警信号的角色？
That's incredible.
那真是不可思议。
Can you give us an easy way to understand this?
你能给我们提供一种容易理解的方式吗？
Think of it like a car engine.
把它想象成汽车的发动机。
A skilled mechanic can often hear a tiny rattle or a change in the engine hum long before the check
在检查灯亮起很久之前，一位技术娴熟的机修工往往就能听到微小的异响或发动机嗡嗡声的变化
engine light actually turns on on your dashboard.
发动机故障灯在你的仪表盘上真正亮起。
These tiny vocal changes are like that engine hum, telling doctors that something subtle is changing
这些细微的声音变化就像发动机的嗡嗡声，告诉医生大脑中有些微妙的变化正在发生
in the brain.
在大脑里。
That is a beautiful and clear analogy.
这是一个非常形象且清晰的类比。
Paying attention to these vocal changes could help people get early support.

Sadly, Pedro lost both of his back legs, making it impossible for him to walk, find food, or escape danger.
不幸的是，佩德罗失去了两条后腿，这使得他不可能行走、寻找食物或逃避危险。
But instead of giving up, a creative team of veterinarians at Louisiana State University decided to
但路易斯安那州立大学一支富有创意的兽医团队并没有放弃，他们决定
build him a custom wheelchair.
给他制作一个定制的轮椅。
A turtle wheelchair?
乌龟轮椅？
How does that work?
那怎么运作呢？
Did they build a tiny engine for him?
他们为他建造了一个微型发动机吗？
