In recent years a groundbreaking new study has been released into the effects of the contraceptive pill. Research from Denmark claimed women on the pill and other forms of hormonal contraception were 70% more likely to be diagnosed with depression than those who were not. And another study has found hormonal contraception was linked to a seemingly dramatic risk of breast cancer. 　　Negative headlines are nothing new for the contraceptive pill - first introduced in 1961, it has had a chequered history with early versions linked to cancer risk and life-threatening blood clots. Yet hormonal contraception remains Britain's most popular form of birth control, and today over three million women take regular doses of synthetic hormones. So should they be worried about its safety? 　　GP Dr Zoe Williams gets behind the headlines in this Horizon investigation. A specially commissioned, nationwide survey reveals the areas of most concern to British women - from mental health to the risk of cancer and drop in libido. With the help of world leading scientists, Zoe finds out if these concerns are justified and by delving deep into the science around the pills side effects Horizon uncovers some striking revelations - from protecting women against cancer to increasing their risk of suicide.

你曾经想过，是什么原因导致一个普通的正常人做出极端的暴力行为么？这个发人深省却又令人不安的提问，正是此次BBC地平线系列纪录片所要探讨的问题。主持人迈克尔·波蒂里奥，将带领你踏上此次探讨人性阴暗面的揭秘之旅。迈克尔发现，我们遭受痛苦的根源和致使我们有暴力倾向的原因，居然跟重度睡眠障碍有关。带着这一命题，迈克尔采访了多位施暴成瘾的男性，并最终发现其实我们每个人都比想象中的更暴力。本片再现了史上最具争议的米尔格拉姆实验（又称权力服从研究），为了测试受测者，是否愿意对无辜的陌生人实施有可能致人死地的电击实验。 　　地平线系列纪录片是英国广播公司BBC制作的一档流行并且播放已久的科学纪录片，于1964年5月2日首播，到2013年为止已有49个系列超过1100集。本系列纪录片从历史、人文、宗教、地理、设计、艺术、生物、哲学、环保、伦理等多个方面，提供世界上最伟大科学家和哲学家一个可以交流他们看法和观点的平台，并将他们对世界的新看法引入到我们的日常知识中来的科教节目。

人们总说宇宙很大，但是它到底有多大？科学家制定了一项雄心勃勃的计划，要画出一幅完整的宇宙地图。然而在可观测宇宙中，有1700亿个类似银河系的星系，不单这些星系在移动，整个宇宙也并非静止不动，甚至有科学家认为，在我们的宇宙以外，还存在着无数个宇宙。究竟宇宙有多大？怎样才能画出它的全貌？研究人员借助最先进的天文观测设备，调动整个小镇的普通居民展开人工作业，以事实验证前人的理论，并得出了震惊世界的结论。

In America it’s an epidemic. Now new evidence raises concern about the UK’s use of prescription opioids. Michael Mosley goes on an immersive journey to ask what can be done about it. 　　The opioid epidemic has devastated America. But what’s the situation here? A new report from Public Health England raises serious concerns about Britain's own relationship with painkillers. Dr Michael Mosley embarks on an immersive journey to Britain’s opioid frontline and meets patients struggling with addiction and GPs fighting a constant battle to help those suffering from chronic pain. He also uncovers worrying evidence of people abusing over-the-counter opioids and discovers how easy it is to buy strong opioids online. 　　Nearly six million people in England and Wales were prescribed an opioid last year. Michael wants to uncover how and why we’re consuming twice the amount of opioids as twenty years ago, especially when the scientific evidence he encounters disturbingly suggests that for the majority of people taking them for chronic pain, these drugs mostly don’t even work. Though a vital tool in our doctors’ armoury to combat acute pain and in cancer and end-of-life care, the Public Health England report revealed that more than half a million people have been on opioids for more than three years. 　　Michael cautions that people taking these drugs should not suddenly stop taking them. Nevertheless, as he discovers, long term or high dose use does leave them exposed to greater risk of side effects including dependency, addiction and even accidental death by overdose. 　　As many as 28 million Britons endure chronic pain - and if we’re to kick what seems like a dangerous national opioid habit, Michael believes that the critical issue is deprescribing. Millions now require help coming off opioids and drug-free alternatives to them. For Michael this is nothing short of a challenge as important as the fight against cancer and heart disease. 　　So how much do people on the ground really know about these powerful painkillers, some of which, including fentanyl, can be many times stronger than heroin? On his travels, Michael meets Karen in Hastings who now believes her five years on increasingly strong opioids ‘turned her into a zombie’. But he also encounters Brenda in Salford who thinks the morphine she has taken for fifteen years to help with her excruciating back pain is the thing that makes her life just about bearable. And he spends time with Vicki whose 50+-a-day over-the-counter painkiller habit led to overdose and near death before she finally admitted her addiction and started detox.

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.
