简介:

  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.

简介:

  This new feature-length biographical film tells the extraordinary and dramatic story of the planet's most famous living scientist, told for the first time in his own words and by those closest to him. Made with unique access to his private life, this is an intimate and moving journey into Stephen Hawking's past and present. Interviewees include Stephen Hawking's sister Mary, his ex-wife Jane, carers and students, as well as colleagues such as Roger Penrose, plus Apollo astronaut Buzz Aldrin, actors Benedict Cumberbatch and Jim Carrey, and Sir Richard Branson This inspirational portrait of an iconic figure relates Hawking's incredible personal journey from boyhood underachiever to scientific genius and multi-million-selling author. And it charts how he overcame being diagnosed with motor neurone disease - and being given just two years to live - to make amazing scientific discoveries and become a symbol of triumph over adversity. Born exactly 300 years after the death of Galileo, Hawking grew up in a family some regarded as eccentric. Always asking questions, he was nicknamed 'Einstein' at school. Hawking blossomed at Oxford, although he only spent an hour a day studying. He noticed that he was becoming clumsy and fell over for no apparent reason. He was diagnosed with motor neurone disease, but nevertheless started a family and embarked on his academic career, finding himself at the heart of a searing scientific debate about the origins of the universe. And as he lost the use of his body, Hawking had to find new ways to think. He went on to write the huge bestseller A Brief History of Time, and the film reveals the high and lows of his resulting fame and fortune.

简介:

  For thousands of years, humans have believed that there were once flying monsters. But did they really exist beyond our nightmares? 220 million years ago dinosaurs were beginning their domination of Earth. But another group of reptiles was about to make an extraordinary leap: pterosaurs were taking control of the skies. The story of how and why these mysterious creatures took to the air is more fantastical than any fiction. In Flying Monsters, David Attenborough the worlds leading naturalist, sets out to uncover the truth about the enigmatic pterosaurs, whose wingspans of up to 40 feet were equal to that of a modern day jet plane. Attenborough works with scientists to understand the incredible story of the evolution of the pterosaurs, a story that unfolds in such stunning locations as New Mexico, the Jurassic Coast of Lyme Regis in Britain, an ancient pterosaur landing site in Southern France and a fossil pit in Germany where near perfect pterosaur specimens have been found. The central question and one of the greatest mysteries in palaeontology is: how and why did pterosaurs fly? How did lizards the size of giraffes defy gravity and soar through prehistoric skies? Driven by the information he finds as he attempts to answer these questions, Attenborough starts to unravel one of sciences more enduring mysteries, discovering that the marvel of pterosaur flight has evolutionary echoes that resonate even today. Flying Monsters is a groundbreaking film that uses cutting-edge 3D technology and CGI to bring the story of giant flying monsters and their prehistoric world to life. Audiences of all ages will be in awe as they enter the world and experience, as never before, REAL Flying Monsters in HD.

  Episode 1 蓝色星球 The Blue Planet 大部分海洋领域仍然隐身在未为人知的神秘面纱中。本集将会综观全系列,介绍海洋的不同范畴,完全揭露海洋的规模、力量与复杂性。探索海洋运作的物理与生物力量,并解释如何影响生命聚集的地理位置。
  Episode 2 幽暗深海 The Deep 在所有的海洋生态中,深海依然是最神秘莫测的地方。在黑暗的迷离世界里,动物都在捉秘藏。有许多生物都像隐了形一样,希望无声无色地避开敌人,隐藏在黑暗之中。为了得到少有的食物,掠食者拥有超大的口与牙齿,潜藏在路边,像捕鼠器般等待;猎物送上门来。
  Episode 3 远洋辽阔 Open Ocean 在广阔的大海中寻找生命的足迹,向着渺无边际的蓝色大海,四面八方伸展开去。在这海洋沙漠中,上面的阳光透不进来,下面则是黑暗深渊。无尽的大海看似荒芜一片,但令人难以置信的是,有许多最奇特的掠食者竟然聚居此处。一簇簇的大海草,为鱼类提供最佳的居所,但也令它们成为掠食者手到擒来的快餐。
  Episode 4 冰封大海 Frozen Seas 首次,我们对南、北极的严峻与艰辛作一比较。在这里,海洋每年的结冰与解冻,主宰生命的节奏。冬天的温度会急降至摄氏零下七十度,只有在春天稍有舒缓,此时阳光普照,浮游生物才会涌现,为众多生物提供养分;在短暂的休息后,寒冰又会随着秋天的风暴卷土重来……
  Episode 5 季节性海域 Seasonal Seas 随着季节的变更,本集将探究太阳能量的转变对海洋生物的影响。我们会前进到最富饶的海洋生态:温和的海洋。水是最重要的能源,巨大的海草森林为成千上万的动物提供庇护。海濑、惊惶失措的七色海葵、鱿鱼、青叶龙等等,都是居住在这个凉快且富饶的水域中的某些例子。
  Episode 6 瑰丽珊瑚海 Coral Seas 沐浴于阳光充沛的温暖清澈热带海域,让珊瑚礁成为海洋中的热带雨林,亦是海床沙漠的绿洲。种类繁多的鱼儿争奇斗艳,并在礁岩中展开弱肉强食的生存竞争。珊瑚为鱼类提供居所之余,也是充满生命力一族。这是一个关于珊瑚的故事:珊瑚礁的形成到终结,乃至于受到灾难式的摧毁……
  Episode 7 潮汐之间 Tidal Seas 潮汐涨退主宰着海洋生物,掌管了生物繁殖的地点与时间。潮汐沼泽地带更是世界上最富饶的地方,丰富的植物供养着为数众多的生物,但是生活仍是坚困。掠食者随时随地都在巡视正片沼泽,水退潮后把动物暴露出来,迫使它们不断迁徙寻找庇护,只有等到再次涨潮时,方能松一口气……
  Episode 8 多变海岸线 Coasts 潮水界限以外,可能是海洋中最具生命力的世界。涨潮不断,只有少数生物会长居于此,其他大部分生物都要由大海中返回海岸,繁殖下一代。海鸟、海龟甚至某些鱼类都会上岸产卵。海狮上岸生育,吸引杀人鲸乘浪而来,让他们成为下一餐的主食。
  Episode 9 隐忧 Deep Trouble 多年来,人类一直挖掘海洋找寻事物与丰富资源,可是我们快要失去这个珍贵宝库了。海洋抵受不了人类残酷的折磨;鱼类不断被捕捞、海洋生态受到严重威胁、经历数千年进化才成熟的珊瑚礁,往往会被盲目扫荡海床的鱼网在瞬间中摧毁……我们可以成功扭转这个局面吗?
  Episode 10 清波作浪 Making Waves 本章系列的成功要素、见证科学家与摄制队的热忱与承诺,把冒险家与大自然搏斗的实录亲身体验与感性的生物研究,一一披露眼前。清波作浪是献给所有热爱海洋研究的朋友之作品。
