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.

主演:Mary Beard
简介:

  Professor Mary Beard, renowned classicist and TV historian, is to explore what life was like in one of the world’s most extraordinary and iconic archaeological sites, in Pompeii: Life Before Death, a new landmark programme for BBC One.
  Mary Beard – a world Pompeii expert and author of Pompeii: Life Of A Roman Town – will be joining an international team as they bring the very latest technology to bear on this most extraordinary of archaeological sites.
  Mary Beard says: “This is a really exciting chance to find out more about the ordinary people who lived in ancient Pompeii. It's a once in a lifetime opportunity. I'm hoping we're going to unlock some if the secrets about who the people were.”
  For the first time, a team is CT scanning and fully investigating the world-famous casts of the bodies to analyse the skeletons trapped within, to ascertain all they can about who they were, where they came from and how they lived. A team is also conducting DNA analysis of the bodies for the first time.
  Elsewhere, the documentary will follow the work of recovering damaged frescoes and mosaics, the excavation and rebuilding of certain key buildings and the organisation and cataloguing of the thousands of astonishing artefacts in the storerooms – from loaves of bread to pet monkeys, paint pots to purses. It will shine a light on the work of archaeologists who are exploring the third of the town that has never been excavated, and will present a unique first look at the complete Pompeii in stunning CGI.
  Using the evidence gleaned from all this research, the BBC One film will piece together a full picture of daily life in Pompeii before the town was destroyed by the eruption of Vesuvius in AD79.

主演:Hannah Fry
简介:

  A witty, exhilarating and mind-expanding exploration of the word of our times - data - with mathematician Dr Hannah Fry. Following in the footsteps of BBC Four's previous gleefully nerdy, award-winning maths films The Joy of Stats, Tails you Win - The Science of Chance and The Joy of Logic, this new high-tech romp reveals exactly what data is and how it is captured, stored, shared and made sense of. Fry also tells the story of the engineers of the data age, people most of us have never heard of despite the fact they brought about a technological and philosophical revolution.
  For Hannah Fry, the joy of data is all about spotting patterns. She's Lecturer in the Mathematics of Cities at UCL as well as being the presenter of the BBC series Trainspotting Live and City in the Sky, and she sees data as the essential bridge between two universes - the tangible, noisy, messy world that we see and experience, and the clean, ordered, elegant world of maths, where everything can be captured beautifully with equations.
  Along the way the film reveals the connection between Scrabble scores and online movie streaming, explains why a herd of Wiltshire dairy cows are wearing pedometers, and uncovers the remarkable network map of Wikipedia. What's the mystery link between 'marmalade' and 'One Direction'?
  The Joy of Data also hails the giant contribution of Claude Shannon, the American mathematician and electrical engineer who, in an attempt to solve the problem of noisy telephone lines, devised a way to digitise all information. It was Shannon, father of the 'bit', who singlehandedly launched the 'information age'. Meanwhile, the green lawns of Britain's National Physical Laboratory host a race between its young apprentices in order to demonstrate how and why data moves quickly and successfully around modern data networks. It's all thanks to the brilliant technique first invented there in the 1960s by Welshman Donald Davies - packet switching - without which there would be no internet as we know it.
  But what of the future, big data and artificial intelligence? Should we be worried by the pace of change, and what our own data could and should be used for? Ultimately, Fry concludes, data has empowered all of us. We must have machines at our side if we're to find patterns in the modern-day data deluge. But, Fry believes, regardless of AI and machine learning, it will always take us to find the meaning in them.
