想象一个地球还是熔岩遍布、火山肆虐的荒凉世界，持续遭受着巨大小行星的猛烈撞击。长久以来，我们都将这些宇宙撞击视为生命的毁灭者，但如果它们恰恰是我们存在的关键呢？探索一个革命性的理论：正是这些剧烈的碰撞，为地球生命的诞生提供了至关重要的成分——水、矿物质和能量。跟随科学家们从月球岩石和远古撞击坑中发掘证据，揭示这些以终结生命而闻名的天体，或许恰恰点燃了生命的火花。

揭开一个曾经强盛帝国的失落秘密。吴哥城，作为东南亚强大的高棉帝国长达500年的都城，曾是世界历史上最大的城市。几个世纪以来，这个非凡的文明繁荣发展，建造了地球上最大的宗教建筑——吴哥窟，并在充满挑战的自然环境中掌握了卓越的城市工程技术。然而，它后来却神秘地被遗弃，最终被丛林吞噬。如今，借助尖端科技和新发现，我们终于可以揭示这个惊人帝国如何崛起称雄于世，以及什么原因最终导致了它的毁灭性崩塌。跟随这个科学侦探故事，它将挑战我们过去对这个古都的一切认知。

想象一个世界，你最好的毛茸茸朋友可以准确地告诉你它们的所思所想。越来越多的狗主人声称这已经成为现实，这要归功于一种创新的发音按钮，它似乎开启了犬类交流的新领域。但这些狗狗真的能理解我们所说的话，并进行回应吗？它们是否真的在创造性地思考，并在新的语境中运用词汇？还是说，这只是一种巧妙的条件反射？为了找到答案，科学家们正在进行历史上规模最大的动物交流研究，分析来自全球数千只狗狗的数百万次按钮按压。见证那些挑战我们对动物智能固有认知的惊人时刻，从似乎能进行对话的狗狗，到那些能以惊人速度学习新词的狗狗。准备好质疑你对狗狗心智的一切认知，并探索它们的语言能力究竟能达到何种程度。

揭开哺乳动物惊人的远古起源，这段故事早在恐龙统治地球之前就已拉开序幕。纵观地球动荡的过往，我们会发现我们最早的祖先之一——似哺乳爬行动物，这些生物形似爬行动物，但已开始演化出哺乳动物的特征——是如何多次从全球灾难中幸存下来的。通过穴居和温血的出现等非凡的适应性进化，它们锻造了一支克服万难、延续至今的血脉。迷人的化石线索和前沿科学向我们揭示了这群坚韧不拔的小型动物如何面对灭绝事件，如何比巨兽活得更久，并最终繁衍出我们今天所知的包括我们人类在内的多样化的哺乳动物世界。

在当今土耳其一处偏远的山坡上，坐落着地球上最古老的神庙——哥贝克力石阵。数个世纪以来，考古学家一直认为它是在文明兴起之前，由游牧的狩猎采集者建造的宗教中心。但突破性的新证据揭示，在这里常年居住达数百年之久的，并非游牧民，而是一个定居于此的复杂狩猎采集者社群。这一惊人发现，或许正是解开人类从狩猎到农耕这一重大转变之谜的关键环节。跟随专家们一起，利用最新的发掘成果和破碎的头骨，拼凑出一个引人入胜的故事，它或将永远改变我们对文明起源的认知。

在阿波罗计划半个世纪后，阿尔忒弥斯任务的目标是将宇航员送回月球，并建立一个月球空间站。跟随阿尔忒弥斯二号任务的工程师和机组人员，踏上为期10天的环月轨道危险之旅。

一种无形、不可预测的大气力量正在全球肆虐，掀翻超级游艇，击落飞机。跟随科学家们，看他们如何争分夺秒地了解这些灾难性天气事件，探索其形成机制、造成毁灭性影响的原因，以及我们未来或许能如何预测它们。从高科技模拟、无人机探入雷暴云，到探究其与气候变化的可能关联，与一线研究人员一起，揭开这些可怕的“雨弹”背后的真相，并寻找应对其日益增长威力的方法。

跟随考古调查，探索2500年前希腊民主制度激动人心的起源。万人坑与暴君被谋杀的古迹遗址，为这种革命性政府形式的诞生提供了全新的解读。

Once a death sentence, cystic fibrosis now faces an apparent miracle cure. Follow the decades-long scientific quest, fueled by desperate parents, that led to this breakthrough with potential implications for the future of personalized medicine.

For millennia, Indigenous peoples in North America have practiced a unique form of science. From navigating the featureless Arctic to building energy-efficient homes in the desert, see how cultural traditions have led to remarkable innovations.

Hidden in the gorges of Southern France lies one of the most stunning decorated caves ever discovered: Chauvet, 'the Sistine Chapel of Paleolithic art.' For thousands of years, this geological wonder was visited only by animals. But around 37,000 years ago people arrived, and some covered its walls with drawings of exceptional beauty. Since its re-discovery in 1994, only a few scientists have been granted access to study it.

An arms race is escalating above us, as military powers vie for control of space. Discover how satellites we rely on are vulnerable to attack, how debris is filling increasingly crowded orbits, and what can be done to protect them.

Brains might be the most complex structures on our planet – so how did evolution build them? To find out, rewind the clock three billion years to trace the evolutionary story of the dolphin, one of the smartest animals alive today. Discover how the first light sensing cells led to eyes that helped wire bodies to think, how a fluke viral infection supercharged the speed of thought, and how the neocortex emerged as early mammals re-wired their brains to attune to the night.

The relentless pursuit of energy, the very act of eating, has profoundly shaped life on Earth. Follow the evolution of the bat to discover the untold story behind every bite we take – one marked by astonishing evolutionary leaps revealing the strange origins of fundamental body parts like powerful jaws.

Earth teems with life in every imaginable form – creatures that walk, swim, slither, and fly. Some grow to astonishing size, like the elephant, while others boast extravagant adaptations, like the hummingbird’s long beak. How did evolution craft such a dazzling variety of body plans? To find the answer, trace life back to its ultimate ancestor, LUCA, and follow the innovations that shaped complexity.

Sex changed everything – evolutionarily speaking, that is. By shuffling the genetic deck it unleashed variation, fueling diversity and throwing evolution into overdrive. But how did this radical innovation begin? From the first exchange of genes to the origins of males and females, uncover the evolutionary leaps that reshaped life.
