From the Chinese Loong to the Filipino Bakunawa, the Scottish Beithir and the Greek Hydra, dragons have inflamed imaginations for millennia. Their ubiquity across world mythology has led many scholars to ponder their possible origins. Could it be that tales of dragons were crafted to make sense of violent weather events? Timothy J. Burbery shares what geomythology has uncovered about dragons. [Directed by Sailesh Gopalan, Lanlan Studios, narrated by Alexandra Panzer, music by André Aires].
从中国的“龙”到菲律宾的“巴库纳瓦”，从苏格兰的“贝蒂尔”到希腊的“九头蛇”，数千年来，龙一直激发着人们的想象力。它们在世界神话中无处不在，引得许多学者探寻其可能的起源。龙的故事是那时的人们为了解释暴风雨或龙卷风等恶劣天气而创作的吗？蒂莫西 · J · 伯伯里（Timothy J. Burbery）分享了地质神话学有关龙的发现。 

Everyone needs time to themselves, and peaceful solitude has stress-relieving benefits. But when being alone is forced upon you, the effects can be surprisingly extensive. And though different people experience distinct effects, symptoms tend to become more severe and persistent the longer one’s isolated. So, how exactly does isolation affect your body and brain? Terry Kupers investigates. [Directed by Camille Bovey, narrated by Addison Anderson, music by Stephen LaRosa].
每个人都需要独处的时光，平和的独处也能帮人缓解压力。可一旦独处成为强加的境遇，其带来的影响会严重到超乎想象。尽管不同人感受到的影响各有不同，但独处的时间越长，产生的种种不适症状往往会越严重、越顽固。那么，独处究竟会对人的身体和大脑造成怎样的影响？特里・库珀斯（Terry Kupers）为你深入剖析。

Dyslexia affects up to 1 in 5 people, but the experience of dyslexia isn't always the same. This difficulty in processing language exists along a spectrum -- one that doesn't necessarily fit with labels like "normal" and "defective." Kelli Sandman-Hurley urges us to think again about dyslexic brain function and to celebrate the neurodiversity of the human brain. [Directed by Marc Christoforidis, narrated by Addison Anderson].
阅读障碍影响着高达五分之一的人，但阅读障碍的经历不一定都一样。处理语言的困难在一定范围内存在 —— 不一定适合贴上像“正常”和“不正常”的标签。教育家凯莉·桑德曼-赫利（Kelli Sandman-Hurley） 敦促我们重新认识有阅读障碍的大脑功能，赞美人脑的神经多样化。 

Is there more than one universe? In this visually rich, action-packed talk, Brian Greene shows how the unanswered questions of physics (starting with a big one: What caused the Big Bang?) have led to the theory that our own universe is just one of many in the "multiverse."
现代宇宙学的核心是一个谜：为什么我们的宇宙如此精美协调地创造出适合生命的必需条件呢？在一些科学新发现的这个绝技之旅，布莱恩·格林恩（Brian Greene）展示了令人难以置信的多元宇宙的想法可能持有这个谜团的答案。
格林恩是哥伦比亚大学物理和数学教授，专注于统一理论已有25年以上，并撰写了多本畅销及非技术类书籍，包括普利策奖决选作品《优雅的宇宙》和《宇宙的织物》——这些作品均被改编成NOVA迷你系列。他最新的著作《隐藏的现实》探讨了宇宙并非唯一的宇宙的可能性。
格林恩认为科学必须以新颖且引人入胜的方式呈现给大众，比如他的现场舞台奇观《提姆边缘的伊卡洛斯》，由菲利普·格拉斯创作原创管弦乐配乐，以及他于2008年与记者特雷西·戴共同创办的年度世界科学节。

When under anesthesia, you can't move, form memories, or — hopefully — feel pain. And while it might just seem like you are asleep for that time, you actually aren't. What's going on? Steven Zheng explains what we know about the science behind anesthesia. [Directed by Zedem Media, narrated by Addison Anderson].
在麻醉药的作用下，你身体不能移动，不能形成记忆。幸亏麻醉，你也感觉不到疼痛。在麻醉后，你看起来像是睡着了，实际上却不是。到底发生了什么呢？Steven Zheng给我们解释了麻醉背后的科学。

As AI races into classrooms, we risk confusing quick and easy answers with true learning, says AI education entrepreneur Priya Lakhani. She explains why being challenged is essential for making knowledge stick — and how AI can be designed to strengthen (not weaken) learning, teaching and thinking.
当 AI 迅速出现在教学情境，我们很容易把「快速又省力的答案」误当成真正的学习。AI 教育创业者普莉亚・拉卡尼（Priya Lakhani）指出，适度的挑战是让知识真正内化的关键，并进一步说明 AI 工具应该如何设计，才能强化——而不是削弱——学习、教学与思考能力。

Sleep positions go by countless creative names— the zombie, mountain climber, free faller, soldier, and more. Yet sleep experts typically simplify them into the basic types: side, stomach, or back. Individual sleep styles are highly personal, but how we spend the night affects our bodies and health in several ways. So, what’s the best position to sleep in? Rachel Marie E. Salas investigates. [Directed by Sofia Pashaei, narrated by Susan Zimmerman, music by Salil Bhayani, cAMP Studio].
睡姿有各式各样创意十足的名称——丧尸式、登山者式、自由落体式，和士兵式等等。但睡眠专家通常会把睡姿简单归为四种基本类型：左侧睡、右侧睡、趴睡、仰睡。每个人的睡姿风格都是非常个人化的，但我们晚上睡觉的方式对我们的身体会有数种影响。所以，最佳睡姿是哪一种？瑞秋‧玛莉‧E‧萨拉斯（Rachel Marie E. Salas）要来讨论这个问题。

As winter approaches, shorter days spark a cascade of changes within the brains of animals. As a result, groundhogs retreat to their burrows for hibernation, weasels’ coats turn from brown to white, and birds cease their singing. And scientists are finding that seasonal behavioral changes similarly happen for some humans. Kelly Rohan digs into what we know about seasonal affective disorder. [Directed by Avi Ofer, narrated by Bethany Cutmore-Scott, music by Cem Misirlioglu].
随着冬季临近，白天渐短在动物大脑中引发连锁反应。土拨鼠退入洞穴冬眠，鼬鼠皮毛由棕转白，鸟儿停止鸣唱。科学家发现，某些人类同样会出现季节性行为变化。凯莉·罗韩（Kelly Rohan）深入探讨了我们对季节性情感障碍的认知。

We are living through what may be the largest economic bubble in history, spanning AI, cryptocurrency and tech company stocks, says financial analyst Henrik Zeberg. He explores why the current AI-crypto bubble mirrors the great economic frenzies of the past, revealing the psychological forces behind them — and why it looks like we're repeating the same patterns again.
我们正在经历有史以来最大的一个经济泡沫，涉及 AI、加密货币、科技公司股票，金融分析师亨里克·泽伯格（Henrik Zeberg）说道。他探究了为什么当前的 AI、加密货币泡沫重现了过往的经济狂热，展现了背后的心理驱动因素，为什么我们像是在重蹈覆辙。
