Now, let's look at what we have lined up for you in today's digest.
现在，让我们来看看今天的文摘中为你准备了什么。
We have some truly groundbreaking medical updates today.
今天我们有一些真正具有突破性的医疗更新。
Oh, we certainly do.
哦，我们确实有。
We will start with a medical miracle where a patient was kept alive using a pig kidney for nine months.
我们将从一个医学奇迹开始，一名患者使用猪肾维持了九个月的生命。
Then we will look at some double -header breakthroughs in Alzheimer's research.
然后我们将看看阿尔茨海默病研究中的一些双重突破。
We will also discuss a dietary showdown between the Mediterranean and keto diets, and a simple 20
我们还将讨论地中海饮食和生酮饮食之间的饮食对决，以及一个简单的20
-minute hack to cure your sleep deprivation brain fog.
分钟小技巧，可治愈因剥夺睡眠导致的脑雾。
And finally, we will talk about a very unusual piece of technology, smart underwear that tracks flatulence.
最后，我们将讨论一项非常不寻常的技术，即可以追踪排气的智能内衣。
Yes, you heard that right.
是的，你没有听错。
It is all about gut health.
这完全与肠道健康有关。
All right, let's kick things off with our lead story, which comes from the field of organ transplantation.
好的，让我们从我们的头条故事开始，它来自器官移植领域。
Scientists have achieved a major milestone.
科学家们取得了重大里程碑。
A man was successfully kept alive with a gene -edited pig kidney for 271 days, which is about nine
一名男子靠基因编辑的猪肾成功维持了271天的生命，这大约是九个
months before he was finally able to receive a human organ.
月后，他终于能够接受人体器官。
Wait a second, Ethan.
等一秒，伊森。
A pig's kidney inside a human?
人体内部的猪肾？
That sounds like pure science fiction.
这听起来纯粹像科幻小说。
Is that even safe?
这真的安全吗？
How does the body not instantly reject it?
身体怎么可能不立刻排斥它呢？
It does sound like science fiction, doesn't it?
这听起来确实像科学幻想，不是吗？
The medical term for this is xenotransplantation.
对此的医学术语是异种移植。
Let me spell that out for our language learners.
让我为我们的语言学习者拼写出来。
X -E -N -O.
X-E-N-O。
Xenotransplantation refers to transplanting organs, tissues, or cells from one species to another,
异种移植是指将器官、组织或细胞从一个物种移植到另一个物种，
in this case from a pig to a human.
在这种情况下，是从猪移植到人。
Ah, xenotransplantation.
啊，异种移植。
That is a brilliant word to learn.
那是一个非常绝妙的词汇。
So how did they stop the human body from attacking the pig kidney?
那么他们是如何阻止人体攻击猪肾的呢？
Well, they used gene editing technology.
嗯，他们使用了基因编辑技术。
You see, normal pig organs have certain sugars and proteins that the human immune system immediately
你看，正常的猪器官含有某些糖类和蛋白质，人类免疫系统会立即
recognizes as foreign enemies.
识别为外来敌人。
By editing the pig's genes, scientists essentially put a disguise on the kidney, hiding those
通过编辑猪的基因，科学家们基本上给肾脏戴上了伪装，隐藏了那些
foreign markers so the human immune system wouldn't reject it.
外来标记，这样人类免疫系统就不会排斥它。
That is absolutely mind -blowing.
那绝对令人震惊。
So the kidney worked just fine for nine months?
所以这个肾脏正常工作了九个月？
Did it actually filter toxins and produce urine like a normal kidney?
它实际上像正常肾脏一样过滤毒素并产生尿液吗？
It functioned beautifully.
它运转得非常完美。
It performed all the essential duties of a human kidney, keeping the patient stable and healthy
它履行了人体肾脏的所有核心职责，使患者保持稳定和健康
until a human donor kidney became available.
直到有了可用的器官捐献者肾脏。
This is a massive victory because it proves that animal organs can serve as a temporary bridge for
这是一个巨大的胜利，因为它证明了动物器官可以作为临时桥梁，
patients on waiting lists.
服务于等候名单上的患者。
A temporary bridge, that is a great metaphor.
临时桥梁，这是一个绝佳的比喻。
Thousands of people die every year waiting for a kidney, so this temporary bridge could literally
每年有成千上万的人在等待肾脏中离世，因此这个临时桥梁字面意义上
save countless lives.
拯救无数生命。
What an incredible start to our morning news.
对于我们的早间新闻来说，这真是一个难以置信的开端。
It really is.
确实如此。
Now, let's move on to our next big story, which is a double breakthrough in Alzheimer's research.
现在，让我们转向下一个重大新闻，这是阿兹海默症研究中的双重突破。
First, a patient in Florida has shown remarkable progress with their brain plaques completely
首先，佛罗里达州的一位患者取得了显著的进展，其大脑斑块已完全
cleared after receiving a new treatment.
在接受新治疗后被清除。
That sounds incredibly promising, but Ethan, let's pause for a moment.
这听起来非常有前景，但伊森，让我们先停顿一下。
Can you explain what brain plaques actually are?
你能解释一下大脑斑块究竟是什么吗？
Why are they such a big deal in Alzheimer's?
为什么它们在阿兹海默症中如此关键？
Of course, think of the brain as a highly efficient city with busy highways of communication.
当然，可以把大脑想象成一座高效的城市，拥有繁忙的通信公路。
In a healthy brain, signals travel freely.
在一个健康的脑部，信号可以自由传递。
But in Alzheimer's disease, a sticky protein called amyloid beta starts to clump together.
但在阿兹海默症中，一种名为β-淀粉样蛋白的黏性蛋白开始凝结成块。
These clumps are called amyloid plaques.
这些凝块被称为淀粉样蛋白斑块。
Think of them like massive piles of trash dumped right in the middle of those highways, blocking the
把它们想象成倾倒在这些公路中央的大堆垃圾，阻挡着
traffic and eventually causing the brain cells to die.
交通，并最终导致脑细胞死亡。
Ah, so clearing those plaques is like bringing in a massive cleanup crew to clear the trash off the
啊，所以清除这些斑块就像是带来一支庞大的清理队伍去清除公路上的垃圾，
highways so the brain traffic can flow normally again. Exactly.
以便大脑交通能够再次正常流动。一点没错。
And this patient saw those plaques completely cleared.
而这位患者的斑块被完全清除了。
But that is only half of the exciting news.
但这仅仅是令人兴奋的新闻的一半。
A second landmark study published in the journal Nature suggests that a major trigger for
发表在《自然》期刊上的第二项里程碑式研究表明，引发
Alzheimer's damage doesn't actually start in the brain at all.
阿兹海默症损伤的主要诱因实际上根本不是在大脑中开始的。
Wait, what?
等等，什么？
If it doesn't start in the brain, where on earth does it start?
如果不是在大脑中开始的，那到底是在哪里开始的呢？
It starts in the peripheral immune system, meaning outside the brain.
它起始于外周免疫系统，也就是大脑之外。
Scientists discovered that certain immune cells, called T -cells, get activated in other parts of the body.
科学家发现，某些被称为T细胞的免疫细胞在身体的其他部位被激活。
They then travel through the bloodstream, cross into the brain, and aggravate the damage caused by
然后它们穿过血液循环，进入大脑，加剧由
another protein called tau. Wow.
另一种被称为Tau的蛋白质所造成的损害。哇。
So the trouble starts outside the brain's borders.
因此麻烦是从大脑的边界之外开始的。
That is a massive paradigm shift.
那是一个巨大的范式转变。
It is like discovering that the intruders in the city actually planned their attack from a
这就像发现城市里的入侵者实际上是从
neighboring town.
邻近的城镇策划攻击一样。
Spot on.
完全正确。
This is huge because it means we might be able to develop treatments that target these immune cells
这非常重大，因为这意味着我们可能能够开发出针对这些免疫细胞的治疗方法
before they even reach the brain, making it much easier to prevent or slow down the disease.
在其到达大脑之前，从而大幅降低预防或延缓该疾病的难度。
That is incredibly hopeful.
这令人难以置信地充满希望。
It shows how interconnected our entire body is.
这表明我们整个身体是多么紧密相连。
Speaking of keeping our bodies healthy, let's talk about our third story, the battle of the diets.
说到保持身体健康，让我们聊聊第三个故事：饮食之战。
We hear so much about the Mediterranean diet and the keto diet.
我们听到过许多关于地中海饮食和生酮饮食的讨论。
What is the new finding here?
这里有什么新发现吗？
Well, a new study published in Eating Well suggests that the keto diet might have a surprising edge
发表在《Eating Well》上的最新研究表明，生酮饮食可能具有意想不到的优势
over the Mediterranean diet when it comes to liver health, specifically for reducing liver fat in
相比于地中海饮食而言，特别是在降低肝脏脂肪方面，针对
people with obesity. Really?
患有肥胖症的人群。真的吗？
The keto diet?
生酮饮食？
Isn't that the one where people eat lots of fats and almost zero carbohydrates?
难道不是人们吃很多脂肪且几乎零碳水化合物的那个吗？
I always thought eating too much fat was bad for the liver.
我一直以为吃太多脂肪对肝脏不好。
It is a bit counterintuitive, isn't it?
这有点违背直觉，不是吗？
But the study found that a very low -carbohydrate ketogenic diet slashed liver fat by a staggering 67%.
但研究发现，极低碳水化合物的生酮饮食将肝脏脂肪削减了惊人的 67%。
Not only that, it also helped reverse pre -diabetes in several participants.
不仅如此，它还帮助几位受试者逆转了糖尿病前期。
67 % is a massive reduction.
67% 是一个巨大的减少。
But I noticed the study mentions cardiometabolic benefits.
但我注意到研究提到了心血管代谢方面的益处。
That is a pretty complex term.
那是一个相当复杂的术语。
Can you break that down for us? Definitely.
你能为我们解释一下吗？当然可以。
Cardiometabolic is a combination of two words.
心血管代谢是两个词的结合。
Cardio, which relates to the heart, and metabolic, which relates to how your body processes energy
Cardio 与心脏有关，而 代谢 则与身体如何处理能量有关
and blood sugar.
以及血糖。
So cardiometabolic benefits mean the diet helps protect your heart and improves your metabolism at
因此，心血管代谢益处意味着这种饮食有助于保护心脏，并同时改善你的代谢
the same time, reducing the risk of heart disease and diabetes. Aha!
同时降低患心脏病和糖尿病的风险。啊哈！
Cardio for heart, metabolic for energy.
Cardio 代表心脏，metabolic 代表能量。
That makes sense.
那很有道理。
So while the Mediterranean diet is still wonderful and balanced, the keto diet might be a powerful
因此，虽然地中海饮食仍然非常棒且均衡，但生酮饮食可能是一个强大的
short -term tool for those specifically needing to clear out liver fat quickly. Exactly.
对于那些专门需要快速清除肝脏脂肪的人来说，是一个短期工具。完全正确。
Although, giving up pasta and bread can be very difficult for many of us.
不过，放弃意面和面包对我们许多人来说可能非常困难。
Tell me about it.
谁说不是这样呢。
I love my carbs.
我爱我的碳水。
Speaking of struggles, Ethan, I have to admit, I did not sleep very well last night.
说到困难，伊森，我必须承认，我昨晚没睡好。
I'm feeling a bit of that classic morning brain fog.
我感觉有点那种典型的早晨脑雾。
Do you have any good news for me?
你有带来什么好消息吗？
Actually, I do.
实际上，我还真有。
Our fourth story is perfect for you.
我们的第四个故事非常适合你。
A new study shows that just 20 minutes of exercise can help protect your memory and reverse brain
一项新研究表明，只需 20 分钟的运动就能帮助保护你的记忆，并逆转大脑
fog after a short night of sleep.
睡眠不足后的脑雾。
Only 20 minutes?
只需 20 分钟？
That is amazing.
那太令人惊叹了。
But please tell me I do not have to run a marathon or lift heavy weights when I'm already exhausted.
但请告诉我，在 我已经精疲力竭的时候，我不必去跑马拉松或举重。
Not at all.
完全不必。
The researchers found that a single moderate workout, like a brisk walk, a light jog, or a quick
研究人员发现，只需一次适度的锻炼，比如轻快地散步、轻微地慢跑或快速
bicycle ride, competes with a 90 -minute nap in terms of restoring your brain's cognitive performance. Wow!
骑自行车，在恢复大脑认知功能方面的效果就堪比 90 分钟的小睡。哇！
A 20 -minute walk competes with a 90 -minute nap?
20 分钟的散步能与 90 分钟的小睡相媲美？
That is incredibly practical.
那真是难以置信地实用。
Sometimes when you take a long nap, you wake up feeling even more groggy, which is a feeling we call
有时当你睡个长觉醒来，感觉反而更加昏昏沉沉，这种感觉我们称之为
sleep inertia.
睡眠惰性。
But a quick walk actually wakes up the brain cells and gets the oxygen flowing. Precisely.
但快速散步实际上能唤醒脑细胞，促进氧气流动。正是如此。
So next time you are sleep -deprived, instead of reaching for that third cup of coffee or crawling
所以下次当你睡眠不足时，与其伸手去拿第三杯咖啡，或是爬
back into bed, try a quick 20 -minute walk.
回到床上，不如尝试快速散步 20 分钟。
Your brain will thank you.
你的大脑会感谢你的。
I will definitely do that right after the show.
节目一结束我肯定会这么做的。
Now, Ethan, let's move on to our final and perhaps most amusing story of the day.
好了，伊森，让我们来看看今天最后一个，也许也是最好笑的故事。
It involves smart underwear and gas?
它涉及智能内衣和肠胃胀气？
Yes, you heard that correctly.
是的，你没有听错。
Scientists have developed smart underwear equipped with flatulent sensors to help monitor digestive health.
科学家们开发出了配备有肠胃胀气传感器的智能内衣，以帮助监测消化健康。
Oh my goodness!
我的天哪！
Smart underwear that tracks farts?
能追踪放屁的智能内衣？
This sounds hilarious, but is there actual serious science behind it?
这听起来滑稽极了，但背后真的有严肃的科学依据吗？
There absolutely is.
绝对是有的。
You see, the gases we release are a direct product of our gut microbiome digesting fiber and other foods.
你看，我们排放的气体是我们肠道微生物组消化纤维和其他食物的直接产物。
By tracking these gas events, doctors can get a real -time window into our digestive health. Fascinating!
通过追踪这些排气情况，医生可以实时了解我们的消化健康状况。太吸引人了！
So what did the study actually find?
那么这项研究实际上发现了什么？
Well, in a trial using these smart undergarments, the sensors logged that people passed gas an
嗯，在一项使用这些智能内衣的试验中，传感器记录下人们排气
average of 32 times a day.
平均每天 32 次。
That's double the standard figure usually found in medical textbooks, which is about 15 times a day.
这是医学教科书中常见标准数字的两倍，教科书上的数据大约是每天 15 次。
Double the standard?
是标准的两倍？
It seems we are all much more active in that department than we care to admit.
看来我们在那方面都比我们愿意承认的要活跃得多。
It's actually a very clever way to track food intolerances, IBS, or how well our gut bacteria are
这实际上是一种追踪食物不耐受、肠易激综合征或我们肠道细菌健康状况的非常聪明的方式，
doing, without needing invasive procedures.
而且不需要侵入性检查。
It really is.
确实是这样。
It shows that even the most embarrassing aspects of human biology can offer vital clues to keeping
这表明，即使是人类生物学中最令人尴尬的方面，也能为保持
us healthy.
我们健康提供关键线索。
Science truly leaves no stone unturned.
科学真正不会留下任何未翻动的角落。
What a funny and informative note to end on.
作为结尾，这真是既有趣又增长见识。
And that wraps up our main stories for today.
今天的主要新闻到这里就收尾了。
It does.
确实如此。
Now, let's keep our brains active with a quick knowledge question based on what we discussed today.
现在，让我们通 过一个基于今天讨论内容的快速知识提问来保持大脑活跃。
Yes, let's do a quick quiz for our listeners.
好的，让我们为听众朋友们做个快速小测验。
Alright, here is the question.
好的，问题来了。
What is the term used to describe the transplantation of organs or tissues from one species to
用来描述将器官或组织从一个物种移植到
another, such as using a pig kidney in a human patient?
另一个物种（例如在人体患者身上使用猪肾脏）的术语是什么？
I will give everyone a few seconds to think about it.
我给大家几秒钟的时间思考一下。
Got your answer?
找到答案了吗？
The correct term is xenotransplantation. Perfect.
正确的术语是异种移植。完美。
And now we have an open question for our wonderful listeners to think about.
现在我们有一个开放性问题供我们精彩的听众朋友们思考。
If you were sleep deprived and had to choose between taking a 90 -minute nap or doing a quick 20
如果你睡眠被剥夺（严重缺乏睡眠），并且必须在小憩 90 分钟或快速进行 20
-minute brisk walk to cure your brain fog, which one would you choose and why?
分钟轻快散步以消除大脑迷糊之间做出选择，你会选择哪一个，为什么？
