Oliver, let us travel straight to the Mediterranean waters of Turkey.
奥利弗，让我们直接前往土耳其的地中海水域。
How did marine archaeologists uncover this historic shipwreck?
海洋考古学家是如何发现这艘历史沉船的？
Our lead story takes us to the waters near Kekova Island along Turkey's southern coast.
我们的头条故事将带我们前往土耳其南部海岸凯科瓦岛附近的水域。
A collaborative team of marine archaeologists and underwater survey specialists were conducting
一个由海洋考古学家和水下调查专家组成的合作团队正在进行
deepwater sonar mapping when they detected an unusual formation resting on the seabed more than 50
深水声纳测绘，当时他们探测到一个异常的地形结构，静静地躺在超过50米
meters below the surface.
米表面以下。
When they deployed remotely operated underwater cameras, they realized they had stumbled upon a
当他们部署远程操作的水下摄像机时，他们意识到自己偶然发现了一艘
remarkably intact Bronze Age vessel dating back approximately 3 ,600 years.
保存得非常完好的青铜时代船只，可追溯到大约3600年前。
3 ,600 years.
3600年。
That is 1 ,600 years before the Common Era.
那是共同纪元前的1600年。
Oliver, to put that in perspective, this ship was sailing the Mediterranean around the time the
奥利弗，换个角度来看，当时这艘船航行在地中海时，正值
legendary Minoan civilization was flourishing in Crete.
传说中的米诺斯文明在克里特岛繁荣发展。
What was this ancient ship carrying when it sank?
这艘古船沉没时载着什么？
The seabed is carpeted with dozens of ceramic storage amphorae and dozens of pillow -shaped copper ingots.
海底铺满了数十个陶瓷储藏双耳罐和数十个枕形铜锭。
Preliminary metallurgical scans show that the copper likely originated from ancient mines on Cyprus,
初步的冶金扫描显示，这些铜很可能源自塞浦路斯的古代矿山，
which was the primary copper hub of the ancient world.
它是古代世界主要的铜贸易中心。
Hold on, Oliver.
等等，奥利弗。
Ingot is a wonderful vocabulary word for our English learners.
锭是我们英语学习者一个绝佳的词汇。
How should we picture an ingot?
我们应该如何想象一个金属锭呢？
An ingot is simply a solid block of purified metal that has been poured into a specific mold for
金属锭简单来说就是一块提纯的金属固体，被浇铸进特定的模具中
easy storage, transport, and trade.
以便于储存、运输和贸易。
Think of a rectangular brick of gold in a bank vault.
想象一下银行金库里长方形的黄金砖。
Or in this ancient case, a heavy slab of raw copper shaped like an ox hide with four handles so
或者在这个古代的例子中，是一块重型 生铜板，形状像牛皮，带有四个把手，以便
sailors could easily haul it onto wooden cargo decks.
水手们可以轻松地把它拖上木制货舱甲板。
That is so vivid.
真是太生动了。
Like giant metal luggage with handles.
就像带把手的巨型金属行李箱。
Why is this particular discovery considered such a monumental milestone in marine archaeology?
为什么这一特定的发现被认为是海洋考古学中如此划时代的里程碑？
Until now, the famous Ulubarun shipwreck, discovered in the 1980s, was widely celebrated as one of
直到现在，20世纪80年代发现的著名的乌鲁布鲁恩沉船一直被广泛赞誉为
the oldest known merchant ships.
已知最古老的商船之 一。
But this newly confirmed site predates Ulubarun by over a century.
但这个新确认的遗址比乌鲁布鲁恩沉船早了一个多世纪。
By using digital photogrammetry, which stitches thousands of underwater photographs into a
通过使用数字摄影测量技术，该技术将数千张水下照片拼接成
millimeter accurate three -dimensional map, archaeologists can study the ship's construction without
一张精确到毫米的三维地图，考古学家可以研究船只的结构，而不会
disturbing the fragile timbers buried in the silt.
打扰到埋藏在淤泥中的脆弱木材。
It is like having a time capsule sealed in saltwater, showing us that people were daring sailors and
这就像拥有一个封存在盐水中的时间胶囊，向我们展示了数千年前人们就是勇敢的水手和
international traders thousands of years ago.
国际商人。
What a thrilling cultural headline to start our day.
开启我们一天的文化头条真是激动人心。
It certainly shows human ingenuity across millennia.
它确实展现了数千年来人类的智慧。
And speaking of how we live our lives, let us transition from how ancient mariners navigated by the
说到我们如何生活，让我们从古代水手如何依靠晨光导航过渡到
morning sun to how our modern bodies respond to morning light.
早晨的太阳到我们现代人的身体如何对清晨的光线作出反应。
Our second story is a health science feature that hits close to home for everyone listening. Yes!
我们的第二个故事是一个与每个听众息息相关的健康科学专题。是的！
A fascinating scientific report featured in the Washington Post explains that if you struggle to
《华盛顿邮报》上的一篇迷人的科学报告解释说，如果你很难
fall asleep at night, the real culprit might not be what you do at bedtime, but what you do right
晚上入睡困难，真正的罪魁祸首可能不是你在临睡前做的事，而是你...
after you wake up in the morning.
早上醒来后立刻做的事。
Oliver, how on earth does my 7 o 'clock morning routine affect my sleep 16 hours later?
奥利弗，我7点的早晨常规究竟是如何影响我16小时后的睡眠的？
It all comes down to our internal circadian rhythm, which is governed by a tiny cluster of neurons
这一切都归结为我们内部的昼夜节律，它由一群微小的...
in the brain called the suprachiasmatic nucleus.
大脑中被称为视交叉上核的一小群神经元控制。
The suprachiasmatic nucleus.
这枚视交叉上核。
That sounds like a mouthful of syllables.
听起来像是一嘴的音节。
Amelia needs a simple metaphor, Oliver.
艾米莉亚需要一个简单的隐喻，奥利弗。
Think of the suprachiasmatic nucleus as the master conductor of an internal orchestra.
把视交叉上核想象成一个内部管弦乐队的首席指挥。
Every cell and organ in your body has its own biological clock, but they all take their tempo from
你体内的每个细胞和器官都有自己的生物钟，但它们都从...
this master conductor.
这位首席指挥那里获取节奏。
And the master conductor synchronizes its timing based on one primary external signal, morning light
并且这位首席指挥根据一个主要的外界信号——早晨的光线，来同步其时间
entering your eyes.
进入你的眼睛。
So sunlight is the conductor's baton.
所以阳光就是指挥的指挥棒。
When natural light hits our retinas, the conductor taps his stand and tells the whole body that
当自然光照射到我们的视网膜上时，指挥敲击他的指挥台，告诉整个身体...
daytime performance has officially begun. Exactly.
白天的表演已正式开始。没错。
When bright morning sunlight reaches your eyes, your brain initiates what neuroscientists call the
当明亮的早晨阳光到达你的眼睛时，你的大脑会启动神经科学家所称的
cortisol awakening response.
皮质醇觉醒反应。
This healthy spike in cortisol raises your body temperature, sharpens alertness, and starts a
皮质醇这种健康的激增会提高你的体温，增强警觉性，并启动一个...
biological timer.
生物计时器。
Approximately 14 to 16 hours later, your brain automatically begins releasing melatonin, the hormone
大约14到16小时后，你的大脑会自动开始释放褪黑素，这种激素...
that creates deep, restorative sleep. Aha.
可以创造深度、具有恢复性的睡眠。啊哈。
But if we stay inside a dark bedroom, keep the curtains shut, or scroll through a dim smartphone
但是如果我们呆在黑暗的卧室里，把窗帘拉上，或者在...
screen under our bed covers, the master conductor never gets that clear signal.
被窝里翻看昏暗的智能手机屏幕，首席指挥就永远收不到那个清晰 的信号。
So what common morning mistakes are scientists warning against?
那么科学家们正在警告哪些常见的早晨错误呢？
Researchers point out three widespread habits.
研究人员指出了三个普遍的习惯。
First, repeatedly pressing the snooze button.
首先，反复按下贪睡按钮。
When you drift back to sleep for seven or eight minutes, your brain enters a fragmented sleep cycle
当你再次入睡七八分钟时，你的大脑会进入一个片段化的睡眠周期
that produces severe sleep inertia, leaving you feeling groggy for hours.
这会产生严重的睡眠惯性，让你感到昏昏沉沉好几个小时。
Second, drinking heavy doses of caffeine within five minutes of waking. Wait.
第二，醒来后五分钟内饮用大剂量的咖啡因。等等。
No coffee immediately upon waking?
醒来后立即不喝咖啡？
Oliver, half our listeners just gasped.
奥利弗，我们一半的听众刚刚倒吸了一口气。
Why should we delay that first cup?
我们为什么要推迟喝第一杯咖啡呢？
Because when you sleep, your brain clears out a chemical called adenosine, which creates sleep
因为当你睡觉时，你的大脑会清除一种叫做腺苷的化学物质...
pressure throughout the day.
它会在一天中产生睡眠压力。
If you flood your system with caffeine before your natural cortisol peaks, caffeine temporarily
如果你在自然皮质醇达到峰值之前让你的体内充满咖啡因，咖啡因会暂时
blocks the remaining adenosine receptors instead of letting your body naturally clear them.
阻断剩余的腺苷受体，而不是让你的身体自然清除它们。
That creates a sharp energy crash in the early afternoon, which tempts you to drink more caffeine
这会在下午早些时候造成严重的精力崩溃，这会诱使你喝更多的咖啡因
late in the day, sabotaging your nighttime sleep.
在一天晚些时候，从而破坏你的夜间睡眠。
That makes total scientific sense.
这完全符合科学逻辑。
So the winning morning prescription is delightfully simple.
所以这个制胜的清晨秘诀极其简单。
Skip the snooze button.
不要按贪睡按钮。
Step outside for 10 to 15 minutes of natural daylight and wait 60 to 90 minutes before enjoying that
走到室外享受 10 到 15 分钟的自然日光，等待 60 到 90 分钟后再享用那杯
delicious cup of coffee.
美味的咖啡。
Your body clock will run like a Swiss watch.
你的生物钟将像瑞士手表一样精准运行。
Spot on, Amelia.
完全正确，阿梅莉亚。
And looking out our windows brings us smoothly into our third headline, an ingenious revolution in
眺望窗外让我们顺利进入第三个头条新闻，这是一个巧妙的革命，关于
green building materials known as transparent wood.
被称为透明木材的绿色建筑材料。
Transparent wood.
透明木材。
Now, that sounds like pure science fiction, Oliver.
听起来纯粹是科幻小说，奥利弗。
When I think of wood, I picture solid brown tree trunks.
当我想到木头时，我脑海中浮现的是结实的棕色树干。
How can wood be as clear as a glass window?
木头怎么能像玻璃窗一样透明呢？
It is an elegant application of biomimicry and green chemistry.
这是仿生学和绿色化学的一个优雅应用。
Traditional wood gets its brown color and stiffness from a natural polymer called lignin, which
传统木材的棕色和刚度来自一种叫做木质素的天然聚合物，它
absorbs light.
吸收光线。
Scientists strip away the light -absorbing lignin using an eco -friendly chemical bath, leaving behind
科学家使用环保化学溶液剥离吸光的木质素，留下
a delicate, white skeletal structure of natural cellulose tubes.
由天然纤维素管构成的精致白色骨架结构。
Then, they infiltrate those microchannels with a bio -based polymer that has the exact same optical
然后，他们用一种具有完全相同光学折射率的生物基聚合物渗入这些微通道
refractive index as cellulose.
与纤维素相同的折射率。
And just like that, light passes straight through without bouncing or scattering.
就这样，光线笔直穿过，没有反射或散射。
Oliver, why would architects want transparent wood instead of ordinary glass?
奥利弗，为什么建筑师想要透明木材而不是普通玻璃？
Because it possesses extraordinary physical advantages.
因为它拥有非凡的物理优势。
First, transparent wood is nearly shatterproof.
首先，透明木材几乎是防碎的。
If you strike it with a heavy object, it bends or dents rather than shattering into dangerous, sharp shards.
如果你用重物打击它，它会弯曲或凹陷，而不是破碎成危险的锋利碎片。
Second, and most importantly, it is a phenomenal thermal insulator.
第二，也是最重要的，它是一个卓越的绝热体。
It provides more than three times the thermal insulation of standard glass panels.
它提供的隔热性能是标准玻璃面板的三倍以上。
Three times the insulation.
三倍的隔热性能。
In modern cities, enormous amounts of energy are wasted because skyscraper glass lets summer heat in
在现代城市中，大量的能源被浪费了，因为摩天大楼的玻璃让夏天的热量进入
and winter warmth out.
并让冬天的温暖流失。
If building facades use transparent wood, heating and air conditioning bills could drop
如果建筑物立面使用透明木材，供暖和空调账单可能会大幅下降
significantly, cutting global carbon footprints. Precisely.
显著减少全球碳足迹。完全正确。
Furthermore, transparent wood distributes daylight evenly across indoor spaces as soft, glare -free
此外，透明木材将日光均匀地分布在室内空间，作为柔和、无眩光的
illumination, reducing the need for artificial ceiling lighting during the day.
照明，减少了白天对人工吸顶灯的需求。
It turns walls into glowing, energy -saving light panels made from renewable trees.
它将墙壁变成由可再生树木制成的发光、节能的光面板。
Nature provides the best engineering blueprints if we only know where to look.
如果我们知道去哪里寻找，大自然就会提供最好的工程蓝图。
From high -tech materials that refresh our built environment, let us conclude this morning with a
从刷新我们建筑环境的高科技材料开始，让我们以一个清晨的...来总结
simple habit that refreshes our mental well -being, the psychology of micro -adventures. Indeed.
刷新我们心理健康的简单习惯——微探险心理学来结束。确实如此。
Our final story explores a growing movement supported by behavioral psychologists.
我们的最后一个故事探讨了一个得到行为心理学家支持的日益增长的运动。
In a world where many people feel trapped in repetitive daily routines and cannot easily take long
在一个许多人感到被困在重复的日常生活中而无法轻易进行长时间的
vacations, researchers are highlighting the mental health power of micro -adventures.
度假的世界里，研究人员正在强调微探险对心理健康的强大作用。
Micro -adventures.
微探险。
Let us define this cheerful term for our audience.
让我们为观众定义这个愉快的术语。
What qualifies as a micro -adventure, Oliver?
什么才算符合微探险的条件，奥利弗？
A micro -adventure is a short, simple, inexpensive, and local activity that temporarily breaks your
微探险是一项简短、简单、不昂贵且本地化的活动，它会暂时打破你的
established daily pattern.
既定的日常生活模式。
It does not require booking an airline ticket or buying expensive gear.
这不需要预订机票或购买昂贵的装备。
It could be waking up 30 minutes early to watch the sunrise from a nearby hillside, taking a
这可能是早起 30 分钟去附近的山坡上看日出，
completely unfamiliar walking route home from work, or visiting a neighborhood market you have never
走一条完全陌生的下班步行路线，亦或是去逛一个你从未
stepped inside.
踏入过的社区市场。
That sounds so accessible.
这听起来太容易实现了。
But why does doing something so small produce such a measurable boost in our happiness?
但为什么做这么小的事情，能给我们带来如此可衡量的幸福感提升呢？
Cognitive psychologists explain that when we follow identical habits day in and day out, our brain
认知心理学家解释说，当我们日复一日地遵循相同的习惯时，我们的大脑
switches to autopilot mode to save energy.
就会切换到自动驾驶模式以节省能量。
When autopilot takes over, our days blur together and mental fatigue sets in.
当自动驾驶接管时，我们的日子就会变得模糊，精神疲劳也会随之而来。
However, when you intentionally introduce a novel experience, your brain releases dopamine, a
然而，当你刻意引入一桩新奇的体验时，你的大脑会释放多巴胺，
neurotransmitter linked to curiosity and positive motivation.
一种与好奇心和积极动机有关的神经递质。
Novelty stimulates neuroplasticity, stretching your attention and restoring mental energy.
新奇感能刺激神经可塑性，拓展你的注意力并恢复精神能量。
It shakes up our mental snow globe.
它打破了我们精神上的雪球。
Instead of waiting for a two -week holiday six months from now, we can inject a splash of adventure
与其等待六个月后的两周假期，我们完全可以把一丝冒险色彩注入
right into an ordinary Tuesday afternoon.
到一个普通的周二下午。
I love that philosophy so much.
我太喜欢这种人生哲学了。
It brings a sense of wonder right back to our everyday lives.
它把一种奇妙的感觉带回了我们的日常生活。
Let us take a quick look back at the journey we took together this morning.
让我们简要回顾一下今天早上我们一起经历的旅程。
We dived into the turquoise waters of Turkey to explore the oldest Bronze Age shipwreck ever found,
