The psychologist Kimberley Wilson lays bear the truism ‘we are what we eat’. In Unprocessed: How the Food We Eat is Fuelling our Mental Health Crisis she bring into sharp focus the known links between diet, brain, behaviour and mental health. She tells Tom Sutcliffe how the government’s failure to address poor nutrition is a catastrophe.Rebecca O’Connell’s research focuses on the social, cultural and economic reasons that shape what children and families eat, and the part food plays in their everyday lives. With the cost of living crisis and an increase in families suffering food poverty, she looks at the capacity to ‘choose’ to buy healthier food, and what other countries, like Portugal, have achieved in prioritising school meals. But what about the food itself and how it’s grown? The author of The Ethical Carnivore, Louise Gray, turns her attention to fruit and veg in her latest book, Avocado Anxiety And Other Stories About Where Your Food Comes From. Tracking from farm to table, Gray discovers the impact that growing fruits and vegetables has on the planet.Producer: Katy Hickman

Tom Sutcliffe talks to three historians about the crimes of WWII and the shifting geopolitics, and the lasting reverberations today with the war in Ukraine. Dan Stone’s new book, The Holocaust - An Unfinished History moves beyond the concentration camps to reveal the true extent of the killing in towns and villages, and the depth of collaboration across the continent – from Norway to Romania. On BBC World Service and BBC Sounds Catherine Merridale uncovers the complex story of loss and silence about the murder of Soviet Jews during the Nazi invasion in 1941, and the extraordinary testimony of what was happening, detailed in The Black Book. Bernard Wasserstein’s family originally came from Krakowiec and in A Small Town in Ukraine he traces the arc of history across centuries of religious and political conflict through the fortunes of its inhabitants – from the earlier invasions of Cossaks, Turks and Swedes to the horrors of WWII and today’s war with Russia.

The architect Sandra Youkhana takes readers on a tour of the structures of modern digital worlds in Videogame Atlas (co-authored with Luke Caspar Pearson). From Minecraft to Assassin’s Creed Unity she examines the real-world architectural theory that underpins these fantasy worlds, and their influence on concrete designs today.The journalist Louise Blain presents BBC Radio 3’s monthly Sound of Gaming which showcases the latest and best gaming soundtracks. She explores how composers help create not only the atmosphere in a game, immersing players in these invented worlds, but their music is also integral to the game’s structure and design. Adrian Hon spent a decade co-creating the hit game Zombies, Run but has become increasingly disillusioned with the way real world institutions – corporations, governments and schools – are using gamification to monitor and control behaviour. In You’ve Been Played he shows how the elements of game playing have been co-opted as tools for profit and coercion.Producer: Katy HickmanImage Credit: Map of the game 'Katamari Damacy' by Sandra Youkhana and Luke Caspar Pearson from 'Videogame Atlas: Mapping Interactive Worlds'

From Europe’s perspective Christopher Columbus ‘discovered’ America in 1492. But the historian Caroline Dodds Pennock shifts the focus in her new book, On Savage Shores, to explore what the great civilisations of the Americas – the Aztecs, Maya, Totonacs, Inuit and others – found in return. The stories of Indigenous Americans abroad are ones of abduction, loss and cultural appropriation, but also bafflement at the lives and beliefs in 15th century Europe. On Savage Shores is BBC Radio 4's Book of the Week.Iokiñe Rodríguez Fernandez is a Venezuelan sociologist who co-founded Grupo Confluencias, a consortium of Latin American conflict resolution practitioners.

In Not So Black and White: A History of Race from White Supremacy to Identity Politics Kenan Malik questions what he sees as lazy assumptions about race and culture. He retells the forgotten history of a racialised working class which sits uncomfortably with today’s obsession with ‘white privilege’. He tells Tom Sutcliffe that we need to confront the issues facing society in terms of class and inequality, and not in terms of identity. The academic Francesca Sobande believes people’s racial identity is a key factor in their experiences and how they are treated. Black Oot Here, co-authored with layla-roxanne hill, explores the history and contemporary lives of Black people in Scotland. The prize winning poet Don Paterson grew up on a working-class council housing estate in Dundee in Scotland. He looks back at that time in his memoir, Toy Fights, interweaving the moments of love, joy and musical delight with the dark side of growing up surrounded by poverty.Producer: Katy HickmanImage credit: '40 George Square' by Francesca Sobande

The award-winning social psychologist Dacher Keltner believes he’s found the answer to happiness: finding awe. In his new book, Awe: The Transformative Power of Everyday Wonder, he shows how this elusive, but powerful, emotion can have physical and psychological effects, impacting our bodies and brains. Anna Lapwood is an organist and conductor, and currently the Director of Music at Pembroke College, Cambridge. She is also a great believer in the transformative power of music. She regularly plays the Royal Albert Hall’s organ – described as ‘the voice of Jupiter’ – and believes listeners can feel the wonder vibrating through the music.Looking up at the night sky and contemplating galaxies far away is often seen as a sure way to elicit wonder, but the physicist Felix Flicker argues that it can be found much smaller and much closer to home. In The Magick of Matter he shows how truly inspiring crystalline specks of dust can be, and when they're combined the sky’s the limit.Producer: Katy HickmanImage: Anna Lapwood - Leeds Town Hall (Credit Tom Arber)

In this first major biography about his life Jennifer Homans offers an intimate portrait of the man who co-founded the New York City Ballet and brought the art form so spectacularly into the modern age. She explores his life and legacy, revealing a complicated genius who was inspired to choreograph dances from subjects as diverse as Spinoza’s philosophy to Orthodox icons, disrupting the norms of ballet and pushing the dancers into creative worlds of abstraction.Wayne McGregor is a contemporary titan of the dance world. He has just returned from Toronto where his ballet based on Margaret Atwood’s post-apocalyptic book, MADDADDAM, had its world premiere in a joint production for The Royal Ballet and the National Ballet of Canada. Wayne McGregor’s own dance company is celebrating its thirtieth anniversary and since its inception has been the experimental and creative forum for Wayne’s innovative choreographic style.Ballet Black was founded by Cassa Pancho just over twenty years ago in response to the lack of racial diversity in ballet and offers dancers of Black and Asian descent a platform to showcase their talents. The company has gone from strength to strength, continually overturning stereotypes and transforming the landscape of classical dance.

Johan Eklöf is a Swedish bat scientist on a mission. In The Darkness Manifesto (translated by Elizabeth DeNoma) he warns how light pollution is threatening the ancient rhythms of life. Many creatures across the world come to life at night – with bats specially adapted to fly using echolocation. By keeping the lights on we are disrupting entire ecosystems.But darkness can appear alien and frightening. The writer Kate Summerscale explores the phobias that haunt the imagination as the lights go off: nyctophobia, xylophobia and hypnophobia – intense and morbid fears of the dark, of forests and of falling asleep. But why do bumps in the night sound so much more unnerving than during the day? The neuroscientist Professor Geraint Rees focuses his research on seeking to understand the neural basis of consciousness and he explores how our different senses are integral to the way we perceive and experience the world around us.The forces of light and darkness are pitted against each other in the classic children’s story The Dark is Rising by Susan Cooper, now adapted for BBC World Service radio, starting on Tuesday 20th December. Producer and co-adapter Simon McBurney creates a spine-tingling winter soundscape with the use of binaural sound, giving listeners using headphones a unique immersive experience.Producer: Katy Hickman

It is fifty years since the last manned-flight to the moon. While the Apollo missions have long been superseded by explorations further afield, the science journalist Oliver Morton insists the moon landings remain strong in our cultural imagination. In his 2019 book, The Moon, he explained how a spherical piece of rock had captured the world’s attention, but then been largely ignored. He tells Tom Sutcliffe how scientists and politicians are now once again turning their focus to our nearest neighbour.Throughout history the moon has inspired artists, poets, scientists, writers and musicians the world over. The artist Luke Jerram has created an extraordinary replica of the Moon measuring seven metres in diameter, fusing NASA imagery of the lunar surface, moonlight, and sound composition. The Museum of the Moon has been exhibited hundreds of times – both indoors and outdoors – across the world, and Jerram explains how each installation has stimulated different events. While NASA’s Artemis mission explores sending astronauts back to the Moon as a stepping stone to human exploration to Mars, and celebrity billionaires sell visions of private space travel, Mary-Jane Rubenstein sounds a warning. In Astrotopia: The Dangerous Religion of the Corporate Space Race she sees comparisons with the destructive effects of the centuries-long history of European colonialism. As problems multiply on Earth she dismisses the offer by wealthy messiahs of an other-worldly salvation for a chosen few.Producer: Katy HickmanImage: Museum of the Moon by Luke Jerram, Cork Midsummer Festival, UK, 2017
