Let us jump right into our lead story from deep space.
让我们直接切入来自深空的头条新闻。
Mars is definitely taking center stage today.
今天火星绝对成为了全场焦点。
Tell us about Perseverance, Chloe.
给我们讲讲“毅力号”吧，克洛伊。
How exactly does a robotic rover break a driving record on another planet?
一个机器人探测车究竟是如何在另一个星球上打破驾驶记录的呢？
NASA's Perseverance rover, which has been exploring the ancient lake bed of Jezero Crater since
美国宇航局的“毅力号”探测车自 2021 年以来一直在探索耶泽罗撞击坑的古代湖床...
2021, has officially set the all -time record for the longest autonomous drive on another celestial body.

in history.
在历史上。
Hold on a second, Chloe.
等一下，克洛伊。
When you say autonomous drive, do you mean the rover is literally thinking for itself like a self
当你提到自主驾驶时，你是说这辆探测车真的像自动驾驶汽车一样自己在思考吗？
-driving car?
...汽车吗？
How does it avoid driving off a cliff without someone holding a digital steering wheel?
在没有人握着数字方向盘的情况下，它是如何避免冲下悬崖的呢？
That is the remarkable part.
这正是非凡之处。
Because radio signals between Earth and Mars take anywhere from 5 to 20 minutes to travel one way,
因为地球和火星之间的无线电信号单程需要 5 到 20 分钟不等，
real -time remote driving is physically impossible.
实时远程驾驶在物理上是不可能的。
If an engineer on Earth saw a dangerous boulder ahead and sent a brake command, the rover would have
如果地球上的工程师看到前方有一块危险的巨石并发送刹车指令，探测车...
crashed into the rock 10 minutes earlier.
...已经在 10 分钟前撞上岩石了。
To overcome this obstacle, NASA built an intelligent navigation system called AutoNav.
为了克服这一障碍，美国宇航局构建了一个名为 AutoNav 的智能导航系统。
It uses high -resolution 3D cameras and onboard computers to assess the terrain, identify hazards,
它利用高分辨率 3D 相机和车载计算机来评估地形、识别危险，
and map out the safest route forward in real time.
并实时规划出前行最安全的路线。
That is incredible.
这太不可思议了。
It essentially gives the rover its own set of eyes and a digital brain so it can make smart
这本质上赋予了探测车一双属于它自己的眼睛和一个数字大脑，这样它就能做出...
decisions on the fly.
...即兴做出决定。
That kind of independent mobility will be essential for future missions, especially when humans
这种独立的机动性对于未来的任务至关重要，尤其是当人类...
eventually build permanent bases on the moon and Mars. Precisely.
...最终在月球和火星上建立永久基地。正是如此。
And Mars is remaining in the spotlight because the Japan Aerospace Exploration Agency, known as
火星依然处于焦点之中，因为被称为...
JAXA, has just launched its Martian Moons Exploration Mission, or MMX.
JAXA 刚刚发射了其火星卫星探测任务，简称 MMX。
This spacecraft is traveling toward Phobos and Deimos, the two small and irregularly shaped moons
这艘宇宙飞船正驶向火卫一和火卫二，这两颗形状不规则的小卫星...
orbiting Mars.
...环绕火星运行。
The primary objective is to touch down on Phobos, collect pristine surface samples, and transport
主要任务是在火星 卫一着陆，收集原始的表面样本，并进行运送
them securely back to Earth. Right.
将它们安全地带回地球。没错。
Bringing pieces of a Martian moon back to our home planet?
把火星卫星的碎片带回我们的母星？
That sounds like a plot from a classic science fiction novel.
这听起来像是经典科幻小说里的情节。
Why are planetary scientists so fascinated by Phobos and Deimos?
为什么行星科学家对火卫一和火卫二如此着迷？
From pictures, they look like giant floating potatoes.
从照片上看，它们就像巨大的漂浮土豆。
They might resemble lumpy potatoes, but they hold crucial clues about how planetary systems evolve.
它们可能类似于结块的土豆，但它们蕴含着关于行星系统如何演化的关键线索。
For decades, astronomers have debated their true origins.
几十年来，天文学家一直在争论它们的真正起源。
One hypothesis argues that they are stray asteroids captured by the gravitational pull of Mars
一种假设认为，它们是被火星引力捕获的流浪小行星
billions of years ago.
在数十亿年前。
Another hypothesis suggests they are fragments of debris launched into orbit after a massive cosmic
另一种假设认为，它们是巨大宇宙碰撞火星后发射到轨道上的碎片。
impact collided with Mars.
撞击了火星。
Analyzing physical soil samples in terrestrial laboratories will finally resolve that mystery.
在地球实验室中分析实际的土壤样本最终将解开这个谜团。
Furthermore, because Phobos orbits extremely close to Mars, whenever giant meteorites strike the red
此外，由于火卫一距离火星极近，每当巨大的陨石撞击红色星球时，
planet, clouds of Martian dust are blasted upward and settle on Phobos.
行星上的火星尘埃云被向上喷射并沉降在火卫一上。
So when the Japanese spacecraft scoops up dirt from the moon, it might actually bring home ancient
因此，当日本航天器从该月球上铲起泥土时，它实际上可能会带回古老的
Martian soil as an added bonus. Exactly.
火星土壤作为额外的奖励。没错。
It is like collecting two planetary souvenirs in a single expedition.
这就像在单次远征中收集两个行星纪念品。
Now, let us bring our focus back home to Earth, where marine ecologists have announced an unexpected breakthrough.
现在，让我们把注意力带回地球，海洋生态学家在那里宣布了一项意想不到的突破。
Lucas, if you are feeling unwell and completely exhausted, would a simple physical touch from a
卢卡斯，如果你感到身体不适且完全筋疲力尽，来自
close companion help you recover?
亲密同伴的简单身体接触能帮你恢复吗？
A warm hug always lifts my spirits, Chloe.
一个温暖的拥抱总能振奋我的精神，克洛伊。
But I assume you are not suggesting that marine biologists are prescribing hugs to sick fish.
但队员们猜你并不是说海洋生物学家在给生病的鱼开拥抱处方。
What actually happened in the water?
水中实际上发生了什么？
In a marine research facility, scientists were studying coral bleaching, a severe condition where
在一个海洋研究设施中，科学家们正在研究珊瑚白化，这是一种严重的情况：
heat stress forces corals to expel the colorful photosynthetic algae that provide them with energy.
热应力迫使珊瑚排出为它们提供能量的色彩斑斓的光合藻类。
During an experiment, researchers accidentally placed a dying, bleached coral fragment directly
在一次实验中，研究人员意外地将一块垂死的、白化的珊瑚碎片直接
against a thriving, healthy coral colony so that their tissues touched.
靠在一个繁荣的、健康的珊瑚群体上，使它们的组织接触。
To everyone's astonishment, the dying coral began regenerating almost immediately and made a full
令所有人惊讶的是，濒死的珊瑚几乎立刻开始再生，并在短短七周内完全恢复。
recovery in just seven weeks.
仅用七周便完全恢复。
Wait, it recovered simply because it was touching a healthy neighbor?
等等，它仅仅是因为接触了一个健康的邻居就恢复了？
How is that biologically possible?
这在生物学上怎么可能？
That sounds like pure wizardry.
这听起来像是纯粹的巫术。
It certainly seems like magic, but the secret lies in microscopic cooperation.
这看起来确实像魔法，但秘密在于微观合作。
Corals are not solitary animals.
珊瑚不是独居动物。
They are complex ecosystems made of animal polyps, microscopic algae, and diverse bacterial colonies.
它们是由动物息肉、微观藻类和多样化细菌群落组成的复杂生态系统。
When the healthy coral made physical contact with the sick one, it transferred beneficial
当健康的珊瑚与生病的珊瑚进行身体接触时，它传递了有益的
microorganisms and healthy symbiotic algae directly across its tissue.
微生物和健康的共生藻类直接穿过其组织。
In short, the healthy coral shared its vital nutrients, kick -starting the weakened coral metabolism
简而言之，健康的珊瑚分享了其重要的营养物质，启动了虚弱珊瑚的新陈代谢
and helping it resist disease.
并帮助它抵抗疾病。
That is extraordinary.
这真是非凡。
It is like receiving a natural cellular infusion or having a kind neighbor bring over hot soup and
这就像接受天然的细胞输液，或者让善良的邻居端来热汤和药。
medicine when you are stuck in bed with a terrible fever.
当你因糟糕的发烧而卧床不起时。
That is an apt comparison.
这是一个恰当的比较。
Researchers believe this technique could transform coral restoration projects worldwide.
研究人员认为这项技术可以改造全球的珊瑚修复项目。
Instead of relying on expensive chemical treatments or complex laboratory equipment, conservation
而不是依靠昂贵的化学处理或复杂的实验室设备，保护
teams might be able to heal degraded reefs simply by planting small, healthy donor fragments
团队可能能够通过直接在受损珊瑚头部旁边种植小的、健康的捐赠碎片来治愈退化的礁石。
directly next to damaged coral heads.
直接在受损的珊瑚头旁边。
That offers genuine hope for our endangered marine ecosystems.
这为我们濒危的海洋生态系统提供了真正的希望。
Now, moving from the ocean floor to the damp soil of ancient forests, we have a prehistoric
现在，从海底转移到古代森林潮湿的土壤中，我们拥有一个史前的
discovery that sounds like something out of a paleontology thriller.
一个听起来像是出自古生物学惊悚片里的发现。
Chloe, what is this D -Rex that scientists have identified?
克洛伊，科学家们鉴定出的这个“D-Rex”是什么？
Do not worry, Lucas.
别担心，卢卡斯。
It is not a ferocious carnivorous dinosaur.
它不是一只凶猛的食肉恐龙。
It is actually a newly discovered giant fungus.
它实际上是一种新发现的巨型真菌。
In the lush subtropical forests of southwestern China, researchers discovered a massive wild
在中国西南部郁郁葱葱的亚热带森林里，研究人员发现了一株巨大的野生
mushroom weighing nearly five pounds.
蘑菇，其重量将近五磅。
Genetic sequencing revealed that it represents an entirely new fungal family with an evolutionary
基因测序显示，它代表了一个全新的真菌科，拥有进化史上的
lineage dating back 65 million years, right to the catastrophic asteroid impact that ended the age
谱系，可追溯到6500万年前，直指那场结束了
of the dinosaurs.
恐龙时代的灾难性小行星撞击。
65 million years ago.
6500万年前。
So when that colossal asteroid struck Earth and triggered a global winter, this fungal lineage was
因此，当那颗巨大的小行星撞击地球并引发全球性严冬时，这个真菌谱系
actually flourishing?
实际上还在繁荣生长吗？
It was indeed.
它确实如此。
When the asteroid struck, thick dust clouds blocked the sun, causing vegetation to collapse and
当小行星撞击时，厚厚的尘埃云遮挡了太阳，导致植被崩溃并
starving massive herbivores, which ultimately led to the demise of apex predators like Tyrannosaurus rex.
使庞大的食草动物挨饿，这最终导致了诸如霸王龙等顶级掠食者的消亡。
However, fungi do not require sunlight for photosynthesis.
然而，真菌不需要阳光来进行光合作用。
They are nature's ultimate recyclers.
它们是大自然终极的回收者。
While the surface ecosystem was collapsing, ancient fungi fed on the endless supply of decaying wood
当地面生态系统崩溃时，远古真菌以取之不尽的腐木
and organic matter.
和有机物为食。
That global catastrophe paved the way for this fungal lineage to diversify and survive all the way
那场全球性灾难为这种真菌谱系的多样化和生存铺平了道路，一直延续
into the modern era.
到现代时代。
That puts our planet's history into perspective.
这让我们对我们星球的历史有了正确的视角。
Dinosaurs dominated the landscape for over 100 million years.
恐龙统治了这片土地超过1亿年。
Yet in the end, humble fungi quietly inherited the Earth.
然而最终，卑微的真菌却悄悄地继承了地球。
And speaking of unexpected social behavior, our final story this morning focuses on our closest
说到意想不到的社会行为，我们今天早上的最后一个故事聚焦于我们在
living relatives in the animal kingdom, chimpanzees.
动物界中最亲近的现存亲戚——黑猩猩。
Yes, this fascinating research comes from animal behaviorists studying primate cooperation.
是的，这项迷人的研究来自于研究灵长类动物合作的动物行为学家。
For decades, traditional theory suggested that wild animals act almost exclusively out of immediate
几十年来，传统理论认为野生动物的行为几乎专门出于眼前的
self -interest, such as gathering food calories.
自身利益，例如收集食物热量。
However, scientists conducted a controlled experiment where chimpanzees could pull a mechanical tray
然而，科学家们进行了一项受控实验，黑猩猩可以拉动一个机械托盘
to receive a delicious snack or forego the food to sit beside a partner for a relaxed grooming session.
来获得美味的零食，或者放弃食物，坐在同伴身边进行放松的理毛。
Let me guess.
让我猜猜。
The chimpanzees actually chose companionship over a free meal?
黑猩猩竟然选择陪伴而不是免费的餐食？
They did.
它们确实选了。
In repeated trials, chimpanzees regularly walked past the food tray whenever they had the
在重复的试验中，每当黑猩猩有机会时，它们经常径直走过食物盘
opportunity to groom and bond with a peer.
去与同伴理毛并建立紧密联系。
Researchers found that this altruistic choice was especially common between chimps who already
研究人员发现，这种利他主义的选择在那些已经
maintained long -term friendships.
保持着长期友谊的黑猩猩之间尤为常见。
That is genuinely heartwarming.
这真是太暖心了。
It shows that friendship is not just a modern human invention.
它表明友谊不仅仅是现代人类的发明。
In the wild, having a dependable companion who watches your back, shares resources, and reduces your
在野外，有一个可靠的同伴为你保驾护航、分享资源并减少你
daily stress is worth far more than a single piece of fruit.
日常压力，其价值远超区区一块水果。
Chimpanzees clearly understand that investing in strong social relationships ensures their long -term survival.
黑猩猩清楚地理解，投资于牢固的社会关系可以确保它们的长期生存。
They certainly do.
它们当然明白。
It implies that loyalty, empathy, and social cooperation have deep evolutionary roots that existed
这暗示了忠诚、同理心和社会合作有着深厚的进化根源，这些根源
long before early humans ever walked the savanna.
早在早期人类踏上热带草原之前就已存在。
What an uplifting collection of stories to start our day.
这是多么振奋人心的一组故事，开启了我们的一天。
From self -driving rovers navigating Martian craters and corals healing one another through touch, to
从穿行于火星陨石坑的自动驾驶漫游车、通过触摸相互治愈的珊瑚，到
ancient prehistoric mushrooms and loyal chimpanzees, science continues to show us how interconnected
史前古蘑菇和忠诚的黑猩猩，科学不断向我们展示万物是多么地相互联系
everything truly is.
一切确实如此。
It certainly does.
它确实如此。
Before we conclude this morning's program, we want to leave you with a light -hearted question to
在我们结束今天早晨的节目之前，我们想留给你们一个轻松的问题去
reflect upon during your morning routine.
在你们早晨的例行公事中进行反思。
If you had to make the choice right now, would you give up your favorite morning breakfast pastry
如果你现在必须做出选择，你会放弃你最喜欢的早晨早餐糕点吗？
just to spend 30 uninterrupted minutes catching up with an old friend?
只为了花 30 分钟不间断的时间和老朋友叙旧？
That is a tough call, Chloe, especially if it is a warm cinnamon roll.
这是一个艰难的抉择，克洛伊，尤其是如果它是一个温暖的肉桂卷。
But I think true friendship wins every time.
但我认为真正的友谊每次都会获胜。
That brings us to the end of today's broadcast.
