Good morning and welcome to TalkCast.
早上好，欢迎来到 TalkCast。
Today is October 26, 2026, and we are thrilled to accompany you as you start your morning routine.
今天是2026年10月26日，当您开始早晨的日常时，我们感到非常兴奋能够陪伴您。
Good morning, Lucas, and good morning to all our listeners tuning in from around the world.
早安，卢卡斯，也早安所有来自世界各地收听的听众们。
Grab your morning coffee or tea, wake up your ears, and get ready for an inspiring exploration of
拿起你的早晨咖啡或茶，叫醒你的耳朵，准备好进行一场鼓舞人心的探索
global science, public health, and the living natural world.
全球科学、公共卫生以及生机勃勃的自然世界。
On this morning's show, we have two remarkable stories that illustrate how science, vigilance, and
在今天的早间节目中，我们有两个非凡 的故事，阐明了科学、警惕和
compassion shape our world.
同情心是如何塑造我们的世界的。
First, we delve into the high -stakes work of disease detectives and epidemiologists across Africa,
首先，我们深入探讨非洲各地疾病侦探和流行病学家的生死攸关的工作
who are deploying contact tracing and disease surveillance to halt the spread of a rare pathogen in
他们正在部署接触者追踪和疾病监测，以阻止一种罕见病原体的
its tracks.
将其踪迹彻底扼杀在萌芽状态。
And later in the broadcast, we travel to the southern coast of South Korea for an astonishing
并且在节目稍后，我们将前往韩国南部海岸，讲述一个惊人的
wildlife rescue story.
野生动物救援故事。
A three -meter dusky shark named Bukangi became an unexpected viral superstar after wandering into an
一条名叫布坎吉的长达三米的暗鲨在误入一个城市运河后，意外地成为了一个意想不到的网络巨星。
urban canal, outsmarting a massive rescue mission and teaching marine biologists crucial lessons
城市运河后，智胜了一场大规模的救援行动，并给海洋生物学家传授了关键的教训
about animal navigation.
关于动物导航的重要一课。
Let us begin with our top story this morning.
让我们从今天早上的头条新闻开始。
When an infectious pathogen emerges, the first line of defense is not just medicine.
当一种传染性病原体出现时，防线的第一线不仅仅是药物。
It is information and rapid detective work.
而是信息和迅速的侦查工作。
Health authorities in West Africa, led by the Nigeria Center for Disease Control, alongside the
西非的卫生当局，在尼日利亚疾病控制中心的领导下，联合
World Health Organization and the Africa CDC, are conducting an intensive epidemiological
世界卫生组织和非洲疾控中心，正在进行一项密集的流行病学
investigation following the confirmation of an imported case of the rare Bundibugio virus in Abuja.
调查，此前阿布贾已确认了一起罕见的邦迪布吉奥病毒输入病例。
An imported case in a major capital city like Abuja naturally puts public health teams on high alert.
像阿布贾这样的大型首都城市出现输入性病例，自然会让公共卫生团队高度警惕。
Lucas, what does the situation look like on the ground and what steps are officials taking?
卢卡斯，实地的具体情况如何，官员们正在采取哪些措施？
According to official health bulletins, a traveler who recently arrived on an international flight
根据官方健康简报，一名最近搭乘国际航班抵达的旅客
from Uganda developed symptoms and was placed in medical isolation at a specialized treatment facility.
来自乌干达的旅客出现了症状，并被安置在一家专业治疗机构进行医学隔离。
What makes this significant is that health teams moved swiftly to identify and monitor 44 close
这意义重大之处在于，医疗团队迅速行动，识别并监测了44名密切
contacts, including health care workers, family members, and fellow travelers.
接触者，其中包括医护人员、家庭成员以及同行的旅客。
44 close contacts identified in a matter of days.
仅仅几天时间就识别出了44名密切接触者。
That is an enormous amount of legwork.
这需要进 行巨大量的外勤奔波。
Lucas, for our English learners, can you unpack the term contact tracing?
卢卡斯，对于我们的英语学习者来说，你能解释一下“接触者追踪”这个术语吗？
We hear it often in health news, but what does it actually mean in practice?
我们在健康新闻中经常听到它，但在实际实践中它到底意味着什么呢？
That is an essential concept, Grace.
这是一个核心概念，格蕾丝。
Contact tracing is the process of identifying, notifying, and monitoring anyone who has spent time
接触者追踪是指识别、通知并监测任何在疾病可能传播期间
in close proximity to an infected person during the period when the illness could be transmitted.
与感染者保持密切接近的人的过程。
Public health investigators conduct detailed interviews with the patient, creating a precise
公共卫生调查人员对患者进行详细访谈，从而建立起一个精确的
timeline of their movements.
活动轨迹的时间线。
Once those contacts are found, health workers check in with them daily to watch for any early
一旦找到这些接触者，医护人员就会每天与他们联系，观察是否有任何早期
symptoms and offer guidance.
症状并提供指导。
Think of it like mapping the ripples created when a pebble drops into a quiet pond.
把它想象成绘制当一颗鹅卵石落入平静池塘时产生的涟漪。
If you can track every ripple right from the center before it spreads across the water, you can keep
如果你能在每一个涟漪在水面扩散开来之前，从中心开始追踪它们，你就能让
the entire lake calm and protected.
整个湖泊保持平静并得到保护。
That is a brilliant analogy, Grace.
这是一个极妙的类比，格蕾丝。
By isolating the source and monitoring every ripple, you prevent secondary infections from spreading
通过隔离源头并监测每一个涟漪，你可以防止继发性感染
into the wider community.
向更广泛的社区蔓延。
And that brings us to another key medical term, the incubation period.
这就让我们引出了另一个关键的医学术语——潜伏期。
Ah, the incubation period.
啊，这个潜伏期。
Let me jump in here.
让我在插话说两句。
The incubation period is the silent window between the moment a person is exposed to a virus and the
潜伏期是个人暴露于病毒的瞬间与他们
moment they actually start feeling sick or exhibiting symptoms.
实际开始感到生病或表现出症状的时刻之间那段无声的窗口期。
Exactly right.
完全正确。
For this particular pathogen, that incubation period can last up to 21 days, three full weeks.
对于这种特定的病原体，其潜伏期可持续长达 21 天，整整三个星期。
That is why health workers are actively monitoring all 44 individuals for 21 continuous days.
这就是为什么医护人员正在积极监测所有 44 个人，持续 21 天。
If none of those 44 contacts develop symptoms by the end of that three -week window, the transmission
如果这 44 名接触者在为期三周的窗口期结束时都没有出现症状，那么传播
chain is officially broken.
链条就被正式切断了。
44 people under daily health observation for 21 days.
44 人在进行为期 21 天的每日健康观察。
Rechecking every person every single day is a massive undertaking.
每天重新检查每个人是一项庞大的工程。
But it is precisely how modern disease containment succeeds without causing public alarm. Precisely.
但这正是现代疾病防控在不引起公众恐慌的情况下成功的方式。正是如此。
In addition, epidemiologists are cross -referencing flight manifests and regional travel records
此外，流行病学家正在交叉比对航班旅客名单和区域旅行记录
across East and West Africa to pinpoint exactly where exposure took place.
跨越东西非以精确定位暴露发生的准确地点。
It is a powerful reminder that global health resilience relies on transparent data sharing and
这是一个强有力的提醒，表明全球卫生韧性依赖于透明的数据共享和
methodical community surveillance.
有条不紊的社区监视。
Methodical detective work keeping everyone safe.
有条不紊的侦探工作保障了每个人的安全。
Now, Lucas, speaking of methodical operations and careful monitoring, our next story takes us from
好了，卢卡斯，说到有条不紊的操作和仔细的监测，我们的下一个故事将带我们从
public health tracking to the aquatic world, where an entirely different kind of rescue mission has
公共卫生追踪转向水生世界，在那里一场完全不同类型的救援任务
been unfolding.
正在展开。
That takes us to the bustling maritime city of Busan, South Korea.
这把我们带到了韩国熙熙攘攘的海滨城市釜山。
For the past month, the city has been captivated by an unexpected visitor, a three -meter -long female
在过去的一个月里，这座城市一直被一个意想不到的访客所吸引。
dusky shark that somehow found her way into a shallow artificial canal at the Northport Waterfront Park.
这条 dusky 鲨鱼不知何故游进了北港滨水公园的一条浅水人工运河中。
Three meters long.
三米长。
That is nearly 10 feet.
这将近 10 英尺。
Imagine taking your morning jog along a city promenade and looking down into the canal to see a
想象一下，你沿着城市的海滨长廊晨跑，低头看运河时看到
massive shark fin gliding through the water.
一只巨大的鲨鱼鳍在水中滑行。
And the public reaction was simply staggering, was it not?
公众的反应简直是令人震惊的，不是吗？
Staggering is the right word.
令人震惊是正确的词。
More than 1 .7 million people, 1 ,700 ,000 visitors flocked to the waterfront park just to catch a
超过 170 万人，1,700,000 名游客蜂拥至滨水公园，只为
glimpse of the shark.
瞥一眼这条鲨鱼。
Local residents affectionately nicknamed her Bukangi, inspired by the Korean name for Busan's North Port.
当地居民亲切地给她起名叫 Bukangi，灵感来自釜山北港的韩语名称。
Bukangi quickly became a cultural sensation.
Bukangi 迅速成为一种文化轰动。
YouTubers set up 24 -hour live cameras, local baseball teams created mascot capes, and the city even
YouTube 主播设置了 24 小时直播摄像头，当地棒球队制作了吉祥物披风，这座城市甚至
named her an honorary ambassador.
封她为荣誉大使。
An honorary city ambassador.
一位荣誉城市大使。
I love that.
我太喜欢了。
But while tourists were cheering, marine biologists and city officials were facing a serious dilemma.
但正当游客欢呼雀跃时，海洋生物学家和市官员正面临着严峻的困境。
A concrete urban canal is definitely not a suitable home for an endangered open ocean predator.
混凝土城市运河绝对不是濒危开阔海洋捕食者的合适家园。
You are absolutely right, Grace.
你说得绝对对，格蕾丝。
Dusky sharks are a vulnerable marine species known for traveling long distances in deep, temperate waters.
暗鲨是一种脆弱的海洋物种，以在深厚、温带水域中长途跋涉而闻名。
Marine experts warned that Bukangi was facing two immediate threats.
海洋专家警告说，Bukangi 正面临两个迫在眉睫的威胁。
First, falling seasonal temperatures.
首先，季节性气温下降。
As autumn deepens in Busan, water temperatures in the shallow canal, currently around 21 degrees
随着釜山的秋意渐浓，浅水运河 中的水温目前约为 21 度
Celsius, are projected to drop below 18 degrees Celsius next month.
摄氏度，预计在下个月降至 18 摄氏度以下。
Below 18 degrees Celsius.
低于 18 摄氏度。
And dusky sharks are warm -tempered ocean animals that cannot survive extended periods in cold,
而且暗鲨是温水海洋动物，无法在寒冷中存活很长时间
shallow water.
浅水中。
Plus, inspectors found no evidence that she was hunting or feeding properly inside that concrete canal. Exactly.
另外，检查人员没有发现任何证据表明她在那个混凝土运河里正常捕食或进食。确实如此。
So last week, the Ministry of Oceans and Fisheries, along with Busan municipal authorities and Coast
因此上周，海洋渔业部与釜山市政当局和海岸
Guard teams, launched a meticulously planned operation to coax Bukangi back to the open sea.
警卫队一起发起了一项精心策划的行动，将 Bukangi 引诱回公海。
They used a large floating platform called a pontoon, secured with soft barrier nets.
他们使用了一个叫做浮筒的大型浮动平台，用软阻隔网固定。
A pontoon.
一个浮筒。
For our English learners, a pontoon is a flat, buoyant, floating platform, often used on rivers or harbors.
对于我们的英语学习者来说，浮筒是一个平坦、有浮力的浮动平台，经常用于河流或港口。
How did the rescue team use it to move a three -meter shark?
救援队是如何使用它来移动一条三米长的鲨鱼的？
Dozens of workers stood on the platform, using oars to guide Bukangi gently forward, while ground
数十名工人站在平台上，用桨轻轻引导布坎吉向前，而地面
crews on both banks pulled ropes to advance the platform.
两岸的工作人员拉着绳索使平台前进。
Step by step, over several hours, they slowly escorted the shark along a one -kilometer stretch of
经过几个小时的一步步努力，他们慢慢护送这条鲨鱼沿着运河一公里的路段
the canal, steering her past the marina bridge and out into the deeper waters of the port.
运河，引导她穿过码头桥，游向港口更深的水域。
A one -kilometer escort through an urban canal.
一场穿过城市运河的一公里护航。
It felt like mission accomplished.
感觉像是任务完成了。
Until night fell.
直到夜幕降临。
Tell our listeners what Bukangi did next, Lucas.
告诉我们的听众布坎吉接下来做了什么，卢卡斯。
Well, dusky sharks are remarkably agile and intelligent creatures.
嗯，暗鲨是非常敏捷且聪明的生物。
Later that night, instead of swimming out toward the open ocean, Bukangi circled back, dived beneath
那天晚上晚些时候，布坎吉没有游向开阔的大洋，而是绕回，潜入下方
the outermost net barrier attached to the pontoon and swam right back into the canal.
连接在浮筒上的最外层网障，直接游回了运河。
She slipped right underneath the net?
她就这么从网底下溜过去了？
She basically said, thanks for the tour, but I like my canal.
她基本上是在说，谢谢你们带我兜风，但我还是喜欢我的运河。
But on a serious scientific note, Lucas, why was she so reluctant to leave?
但从严肃的科学角度来看，卢卡斯，为什么她这么不情愿离开？
Why would an ocean predator choose a narrow canal over the open sea?
为什么一个海洋掠食者会选择一条狭窄的运河而不是开阔的大海？
Marine scientists believe two fascinating biological factors are at play.
海洋科学家认为有两个迷人的生物学因素在起作用。
First, climate patterns.
首先，气候模式。
Warming sea temperatures along the Korean peninsula have drawn warm water fish like bluefin tuna
朝鲜半岛沿海变暖的海水吸引了诸如蓝鳍金枪鱼之类的温水鱼
farther north, which likely lured Bukangi into coastal Busan in search of prey.
更向北移动，这很可能诱使布坎吉为了寻找猎物而来到釜山沿海。
But once inside the harbor, she encountered severe sensory disorientation.
但一旦进入港口，她就遇到了严重的感觉定向障碍。
Sensory disorientation?
感觉定向障碍？
What confused her senses?
是什么混淆了她的感官？
Sharks navigate using an extraordinary biological organ called the ampullae of Lorenzini.
鲨鱼利用一个被称为洛伦茨壶腹的非凡生物器官进行导航。
The ampullae of Lorenzini?
洛伦茨壶腹？
That sounds like an ancient incantation.
听起来像是一句古老的咒语。
What in the world are the ampullae of Lorenzini?
这世上到底什么是洛伦茨壶腹？
They are hundreds of microscopic, jelly -filled pores scattered across a shark's snout and head.
它们是数百个散布在鲨鱼吻部和头部的微观、充满果冻状物质的孔隙。
These pores act as electroreceptors, allowing sharks to detect the faint electrical impulses
这些孔隙充当电感受器，使鲨鱼能够探测到微弱的电脉冲
generated by muscle contractions of prey, as well as the Earth's geomagnetic field lines for navigation.
由猎物肌肉收缩产生的电脉冲，以及用于导航的地球地磁场线。
Ah, so think of it like an ultra -sensitive smartphone compass.
啊，所以把它想象成一个超灵敏的智能手机指南针。
But inside a busy industrial canal, surrounded by steel sheet piles, ship engines, underwater
但是在一条繁忙的工业运河里，四周环绕着钢板桩、船舶引擎、水下
cables, and port machinery, that compass goes completely haywire.
电缆和港口机械，那个指南针就会完全失控。
It is like trying to use your phone's GPS while trapped inside a metal elevator surrounded by high
这就像试图在被困于金属电梯内部同时周围环绕着高压电时使用手机的 GPS。
-voltage electrical wires.
-电压电线。
That is an accurate picture, Grace.
这是一个准确的描绘，格蕾丝。
The artificial electromagnetic noise of the harbor made it difficult for her to pinpoint the exit to
港口人工的电磁噪声使她很难精确定位通往开阔海洋的出口。
the open ocean.
开阔的海洋。
Realizing this, authorities have smartly changed their strategy.
意 识到这一点，当局明智地改变了他们的策略。
Instead of forcing her out with stressful herding, they removed the internets, widened her swimming
他们没有用充满压力的驱赶方式逼她出去，而是拆除了网，拓宽了她的游泳
corridor, and shifted to non -invasive ecological monitoring.
通道，并转向了非侵入式的生态监测。
And that patient approach is already showing promising signs.
这种耐心的做法已经显示出有希望的迹象。
Recent observations show Bukangi is now exploring deeper waters near the harbor piers, swimming
最近的观察表明，布坎吉现在正在探索港口码头附近更深的水域，游泳
comfortably below the surface, and gradually orienting herself toward the open sea without human pressure.
在水面下舒适地游动，并在没有人类压力的情况下逐渐将自己导向开阔的大海。
Giving wildlife the time and space to find their own way home.
给野生动物时间和空间去寻找它们自己的回家路。
An inspiring demonstration of how modern cities can respond to unexpected wildlife encounters with
这是一个鼓舞人心的示范，展示了现代城市如何以科学、耐心和同理心来应对意想不到的野生动物遭遇
science, patience, and empathy.
科学、耐心和同理心。
What a morning of discovery.
多么美好的发现之晨啊。
From public health detectives tracing contacts to safeguard human communities, to marine scientists
从追踪接触者以保障人类社区安全的公共卫生侦探，到海洋科学家
respecting the delicate sensory biology of an endangered shark.
尊重一只濒危鲨鱼微妙的感觉生物学。
It reminds us that careful observation and patience are at the heart of good science.
它提醒我们，仔细的观察和耐心是优秀科学的核心。
Well said, Grace.
说得好，格蕾丝。
