Dr Alice Roberts asks one of the great questions about our species: are we still evolving? 　　There's no doubt that we're a product of millions of years of evolution. 　　But thanks to modern technology and medicine, did we escape Darwin's law of the survival of the fittest? 　　Alice follows a trail of clues from ancient human bones to studies of remarkable people living in the most inhospitable parts of the planet and the frontiers of genetic research, to discover if we are still evolving - and where we might be heading.

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.

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.

茫茫宇宙中，是否存在着适合生命安身立命的星球？置身广袤的宇宙，人类又是否是唯一存在着的孤单生物？世界各地一帮具有高度聪明才智，并且训练有素的科学家共同坚持着一个惊人的信念：在浩瀚的宇宙中，可能存在着生命。这是人类曾经尝试过的最“疯狂”的一次实验，去探索宇宙中普遍或偶尔存在的智能生命。然而要证明它，却并非易事。 五十年来，“太阳系外类地智能搜寻小组”在一直观测着银河系，以求来自外星文明的消息。NASA也希望能在十年内再找到50个类似地球的行星。今天，地平线系列纪录片的团队，也成为了“行星搜寻猎队”中的一员。他们曾发现名为“葛利斯581c”（这是迄今已经发现的太阳系外的最类似地球的行星）的“超级地球”，其上很有可能存在着适宜生命存活的环境条件。尽管目前仍毫无效果，但一些激动人心的成就都暗示着外星生命已在银河系的其他地方诞生。

Last year the discovery of a tiny fossilised jawbone hit the headlines. The jawbone, only a few centimetres long, and with 7 rows of teeth, had been found lying abandoned in a dusty museum where it had lain unnoticed for decades. It's rediscovery has caused a sensation in the world of palaeontology because scientists now believe it may be a tiny remnant of a "missing link", an ancient extinct animal that could provide a vital clue in our understanding of one of the great mysteries of science - how, 360 million years ago, a slimy fish-like creature grew legs and walked out of the sea, onto the land, and became our ancestor. This mystery, of how and why, long ago, we grew legs and crawled out of the water, has taken scientists a century to unravel. And this tiny jawbone may be a final clue.

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.

Horizon is BBC Two's flagship 50-minute science documentary series. In September 2004 it celebrated its 40th anniversary and it continues to enjoy outstanding critical acclaim. Recognised as the world leader in its field, it regularly wins a sweep of international science, medical and environmental film accolades, and has recently won the Royal Television Society Award and the Prix Italia. In 2002, the British Academy of Film & Television Arts presented Horizon with the BAFTA Television Award for Best Factual Series or Strand. In 2003 it won the prestigious Images et Science award for best medical documentary and the Carl von Linne Award at the Living Europe film festival in Sweden. That year, a Horizon co-production with WGBH Boston won the Emmy for best documentary.

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.

2013年2月28日，佛罗里达坦帕市东郊住宅区，正在熟睡中的杰夫•布什和他的卧室突然消失得无影无踪。可怕的是，他消失前毫无征兆，杰夫从此杳无音信。他被陷穴吞没了。那么，陷穴是如何形成的？对于陷穴我们能做些什么？在这个不可思议的地理侦探故事片中，伊恩•斯图尔特博士发掘了地球几百万年的历史，以寻找这些问题的答案，并追问是否会有更多陷穴在我们身边出现。
