当我们用红色或蓝色或黄色来描述某样东西为，我们想当然地认为其他人会理解并知道我们要表达的意思。但我们如何能确保我们有着相同的色彩体验呢？颜色仅仅是我们大脑的创造物吗？我们看到的色彩斑斓的世界是完全真实的吗？或者这与认知有关并受我们所说的语言、我们的年龄或甚至我们的国籍影响吗？本期《地平线》节目将寻找色彩对我们的意义，色盲是否有望治愈以及我们是否能扩展人类视野。

For centuries we have dreamt of reaching the centre of the Earth. Now scientists are uncovering a bizarre and alien world that lies 4,000 miles beneath our feet, unlike anything we know on the surface. It is a planet buried within the planet we know, where storms rage within a sea of white-hot metal and a giant forest of crystals make up a metal core the size of the Moon. 　　Horizon follows scientists who are conducting experiments to recreate this core within their own laboratories, with surprising results.

如果你被问到“你知道现在的时间吗”，是否会觉得这是一个太过简单的问题？看看腕上的手表，或是翻出手机，精确到分秒的时间就能被轻易知晓。然而今天，粒子物理学家布莱恩·考克斯教授也如此问到。布莱恩探访了墨西哥的古玛雅金字塔，在那里古玛雅人是靠建神殿来计时的。他惊人地发现，符合地球本身规律的“时间”，从来都不是一天24小时。那么这个我们早已习以为常的“公理”，到底是个物质周期变化的规律，还是我们对于时间和空间认知上的一种错觉呢？ 　　此次BBC地平线系列纪录片的摄制组，将跟随布莱恩教授的脚步，从时间的起点开始入手研究，走访了多个支持“弦理论”的国度，并研究了时间的极限，试图解开这个抽象概念背后的神奇奥秘。

Around the world, a new generation of astronomers are hunting for the most mysterious objects in the universe. Young stars, black holes, even other forms of life. 　　They have created a dazzling new set of super-telescopes that promise to rewrite the story of the heavens. 　　This film follows the men and women who are pushing the limits of science and engineering in some of the most extreme environments on earth. But most strikingly of all, no-one really knows what they will find out there.

David Baddiel, father of two, sets out to answer one of the greatest questions a parent can ask: how best to educate your child. 　　Taking in the latest scientific research, David uncovers some unconventional approaches: from the parent hot-hosing his child to record-breaking feats of maths, to a school that pays hard cash for good grades. 　　David witnesses a ground-breaking experiment that suggests a child's destiny can be predicted at four, and hears the three little words that can ruin a child's chance of success for good. He also uncovers the neurological basis for why teenagers can be stroppy and explosive and has his own brain tinkered with to experience what it is like to struggle at school. 　　Through it all, David's quest remains true: to maximise his child's potential for success and happiness.

Six months after the explosions at the Fukushima nuclear plant and the release of radiation there, Professor Jim Al-Khalili sets out to discover whether nuclear power is safe. 　　He begins in Japan, where he meets some of the tens of thousands of people who have been evacuated from the exclusion zone. He travels to an abandoned village just outside the zone to witness a nuclear clean-up operation. 　　Jim draws on the latest scientific findings from Japan and from the previous explosion at Chernobyl to understand how dangerous the release of radiation is likely to be and what that means for our trust in nuclear power.

本部纪录片是英国BBC地平线系列中的一部。这让我们又爱又恨的神奇液体，就是一种泛滥成灾的成瘾品——酒。戒毒专家约翰·马斯登亲身说法，从专业和个性化的角度探索我们与酒精之间的关系，用科学的观点介绍人们对酒的依赖。 酒精是迄今为止最为广泛使用的药物，当然也是最危险的。那么，为什么这样多的人会饮酒过量？为什么酒精会如此强大的控制着我们的神经？酒精跟基因有关么？如果青少年过早饮酒的真正危害又是什么呢……面对如此之多的疑问，约翰试图与药品设计师开发出实验药物，来取代酒精。在不久的将来，这种药物是否会取代酒精呢？
