Seriously...

Luke Jerram is that rare bird, a genuinely popular yet acclaimed contemporary artist. And he's obsessed with the moon. So he's made one: seven metres wide featuring 120dpi detailed NASA imagery, and he's taking it around the world. This is his story, as well as the moon's..Every day Luke Jerram cycles to his studio across the river in Bristol and watches its dramatic changes. It has the second highest tidal range in the world and it's the moon that makes this happen. Luke's become fascinated with finding out everything he can about the cultural, artistic and poetic significance of the moon, and the latest scientific developments around it. It both reflects our culture and inspires it.Being colourblind he's interested in all forms of light, and moonlight is fascinating and has very particular properties. The fact we see 'the man in the moon' is a perceptual and optical illusion. But again, different cultures see different imagery - in China they see the Hare in the Moon.Luke presents his own story of making these works and hearing people's responses to them, woven in with the new soundtrack he's commissioned from composer Dan Jones. We talk to fellow contemporary moon obsessives James Attlee and Jay Griffiths, but it's all filtered through the very particular consciousness of one artist and his imagination, and the hard slog of his creative process.Producer Beth O'Dea.

How do we prepare for the distant future? Helen Keen meets the people who try to.If our tech society continues then we can leave data for future generations in huge, mundane quantities, detailing our every tweet and Facebook 'like'. But how long could this information be stored? And if society as we know it ends, will our achievements vanish with it? How do we plan for and protect those who will be our distant descendants and yet may have hopes, fears, languages, beliefs, even religions that we simply cannot predict? What if anything can we, should we, pass on?

For centuries tales were shared around the camp-fire; modern settlements share data via wi-fi. But what hasn't changed across the ages is our passion for histories and information - we shape and make sense of our lives by telling stories about what has happened to us, and relax by reading or seeing fictions about the lives of imagined characters. From cave-dwellers to millennials , stories have been organised in pretty much the same way - with a beginning, middle and end, although, in contemporary culture, now less frequently in that order. All storytellers have used techniques of tension, delayed revelation, surprise twists. But - now - the art of narrative is being fundamentally changed by new technologies, which offer fresh ways of telling stories and different places for them to be told, redefine narrative genres, and allow audiences unprecedented opportunities to inter-act with and even co-author the content.In this, the first part of a new three part series, Mark Lawson speaks with some of the leading figures in British TV - including showrunner Jed Mercurio (Line of Duty), producer Nicola Shindler (Red Productions) writer Paula Milne (The Politician's Wife, Angels), Charlotte Moore (BBC Director of Content) - to examine how the stories being told on television in the digital age have adapted to the advent of streaming services, binge-watching and catch-up TV. Mark also visits a cinema in Macclesfield to watch the live broadcast of 'Follies'- staged simultaneously in the West End. He talks with Kwame Kwei-Armah, soon to begin as the Young Vic's Artistic Director, about how the technology involved has brought top-level theatre to a whole new audience and redefined the idea of live spectatorship.

Zoologist and founder of the Sloth Appreciation Society, Lucy Cooke, unleashes her inner sloth to discover why being lazy could actually be the ultimate evolutionary strategy.The explorers of the New World described sloths as 'the lowest form of existence', but sloths are actually some of the most enduring of all tropical mammals. They make up one third of the mammalian biomass in rainforests and have survived some 64 million years - outliving far flashier animals like sabre tooth tigers.The secret to the sloth's success is their slothful nature and their suite of energy-saving adaptations. In fact slothfulness is such a successful strategy, that there are examples all over the animal kingdom, including, surprisingly, worker ants. Recent studies in humans have shown the many health benefits of adopting a slower pace of life. Sleep itself is universal amongst the animal kingdom. All animals do it, but why remains a mystery. What is clear though, is that unleashing your inner couch potato is no bad thing, be you sloth or human.Lucy discovers the genius behind the sloths laid back attitude and fights the corner for laziness.Producer: Alexandra Feachem.

Dreaming of a Dark Christmas, in IcelandAt the darkest time of the year in Iceland scary creatures come out to play. Storyteller Andri Snær Magnason used to be terrified by his grandmother's Christmas tales of Gryla the 900 year old child eating hag and her thirteen troll sons - the Yule Lads - who would come down from the mountains looking for naughty children in the warmth of their homes. These dark lullabies partly hark back to a pre-Christian Christmas when people worshipped the Norse gods.As Iceland opens up to global influences after centuries of isolation Andri travels from farmstead to lava field and reflects on these traditions: whether the elves still crash your house to throw a Christmas party or the cows still talk on New Year's Eve; and what happens when you have to spend Christmas alone, locked inside Ikea?Featuring the Graduale Nobile Choir conducted by Árni Heiðar KarlssonPartially recorded in Binaural Stereo. Listen on headphones for the best effect.Additional sound design by Phil ChannellProducer Neil McCarthy.

Historian and psychoanalyst Daniel Pick of Birkbeck College, University of London tells the story of how aerial bombardment - from Zeppelins to B52s, from H-Bombs to drones - has made the unconscious mind a field of battle.Daniel explores how, in the shadow of the First World War, Freud turned his analytical eye from desire to the 'death drive', and how psychoanalysts probed what might happen if another war came.Would survivors of mass aerial bombardment hold up psychically, or would they collapse into infantile panic? Or would they become uncontrollably aggressive?And why do humans come to be so aggressive in the first place?When the war - and the bombers - did come to Britain, it appeared that survivors were much more stoical and defiant than had been expected.But, as Daniel discovers, brave faces concealed a great deal of psychological damage.With historian Lyndsey Stonebridge, he visits the Wellcome Library to see - courtesy of the Melanie Klein Trust - the case notes of the psychoanalyst Melanie Klein on her analysis of a troubled ten year old boy, 'Richard'.What do Klein's notes, and Richard's extraordinary drawings, reveal about his attitude to being bombed?Daniel examines how, with the advent of the Cold War and the distinct possibility that bombs and missiles could destroy civilisation, technocrats trying to plan for the end of the world coped with staring into the abyss.Finally, Daniel shows how a radical new turn in aerial bombardment opens up this field anew. Nuclear weapons can destroy the planet; but what does it do to the mind to live under the threat of 'surgical' attack by unmanned drones?With: Derek Gregory, Peter Hennessy, Dagmar Herzog, Richard Overy, Lyndsey StonebridgeProducer: Phil Tinline.

Why do some of us do bizarre things in our sleep? Like riding a motorbike, using a shoe to 'phone for a pizza or even having sex while sleeping? These are complex behaviours and yet sleepwalkers aren't aware of what they're doing and often have no memory of their strange night-time activities.These sleep disorders are known as non-REM parasomnias and include conditions like night terrors and sleep eating.So why does it happen? Sleepwalking usually occurs during deep sleep, when something triggers the brain to wake - but not completely. So the areas that control walking and other movement wake up, yet other parts, involved in awareness and rational thinking, remain asleep. What's confusing is that sleepwalkers look awake - their eyes are open - but they're really not awake. They're not really asleep either. The brain is awake and asleep at the same time. We have known this happens in some animals, who can sleep with half of their brain at a time. But recently, we have learnt that similar things can happen in the human brain.In the first of a three-part series, neurologist, Dr Guy Leschziner, talks to patients he's been treating at his sleep clinic at Guy's and St Thomas' hospitals in London. They include Jackie who began sleepwalking as a child and continued her strange night-time behaviour as an adult, riding her motorbike whilst sleeping. We hear from James whose night terrors have become so violent his wife has begged him to get help; from Alex who rescues people from floods in his sleep. And we talk to Tom, whose recent diagnosis of sexsomnia has had a significant impact on his life.These remarkable sleepwalking experiences help us to understand the complex workings of the human brain.Presenter: Dr Guy Leschziner Producer: Sally Abrahams.

Byron Vincent joins the Violence Reduction Unit in Glasgow to see how they turn young men away from lives of violence and chaos. Three years ago, after he discussed his own violent and chaotic youth in a Four Thought talk on Radio 4, Byron was invited to come and speak at the VRU. Since then he has been back several times - now he experiences the unit's work directly. Byron spent two weeks embedded in two of the VRU's programmes, from watching the scheme's participants working in food trucks in the west end of Glasgow to joining the cast at the Royal Military Tattoo in Edinburgh. After hours, and with his powerful personal connection to their lives, Byron has extraordinarily candid conversations with the young men involved in the scheme about fear, insecurity, redemption, love, hope and the real reasons for spiralling violence. But what sacrifices will be required for them to make new lives, free from chaos and violence? Producer: Giles Edwards.

"The more we reinforce the stereotypes of who writes and who reads, the more the notion of exclusivity is reinforced. It takes balls to gatecrash a party."Kit de Waal, published her first novel, My Name is Leon, in 2016 at the age of 55. She has already put her money where her mouth is - using part of the advance she received from Penguin to set up a creative writing scholarship in an attempt to improve working class representation in the arts.Kit knows that - as a writer from a working class background - the success of her debut novel is a rare occurrence. Born to a Caribbean bus driver father and an Irish mother (a cleaner, foster carer and auxiliary nurse), Kit grew up in Birmingham and left school at 15 with no qualifications. She became a secretary with the Crown Prosecution Service and went on to have a career in social services and criminal law. In this feature she explores an issue that is deeply personal to her. She looks back at her own life and trajectory, and takes the listener on a journey around the country to find out what the barriers really are to working class representation in British literature today."There is a difference between working class stories and working class writers. Real equality is when working class writers can write about anything they like - an alien invasion, a nineteenth century courtesan, a medieval war. All we need is the space, the time to do it - oh yes, and some way to pay the bills!"Kit talks to a range of writers, agents and publishers about what the barriers are for writers from working class backgrounds, including Tim Lott, Andrew McMillan, Gena-mour Barrett, CEO of Penguin Random House UK Tom Weldon, Julia Bell, Julia Kingsford, Ben Gwalchmai, Nathan Connolly and Stephen Morrison-Burke (Birmingham poet laureate and the first recipient of the Kit de Waal scholarship).Produced by Mair Bosworth.

Filmmaker Mike Figgis explores the story of edited film, audio and culture, and how the simple process of cutting and splicing has changed the way people view the world.We are living in an age of the edit. From the jump-cuts of Eisenstein and Hitchcock, to the fractured narratives of Virginia Woolf and James Joyce, from the cut-and-paste sounds of musique concrete and hip-hop, to the sensibility of social media (to say nothing of the radio feature itself), it's the edit - the cut, the splice; montage and juxtaposition - that has ushered us into the present. To some, it's the stuff of life itself: chimps, for example, share 99% of our DNA; what matters is the sequencing, the edit.There's a year zero to this story of the edit. From the moment we get up in the morning until we close our eyes at night, the visual reality we perceive is a continuous stream of apparently linked images. That's the way we experienced the world for millennia. Then suddenly, just over a century ago, human beings were confronted with something else: edited film.But this isn't an exercise in cinema history. It's about our present culture. A culture in which the invisible mediating hand of the editor is ever-present. A culture of the 'creative commons' in which we can pull anything out of context and re-edit it (a gif, an internet meme, a mash-up, a parody of a political speech) and make the edit itself become an art form. Cutting, splicing, sampling -- it's all part of the way the world functions now. This is just the beginning.With Vicki Bennett aka People Like Us, Margie Borschke, Walter Murch and Will Self.Producer: Martin Williams.
