Stonehenge is one of Britain’s most iconic monuments: an ancient stone circle still shrouded in layers of speculation and folklore. A new exhibition at the British Museum looks at the human story behind the stones, and offers new insights into the beliefs, rituals and worldview of our Neolithic ancestors. The curator Neil Wilkin tells Adam Rutherford about one of the objects on show – the metal Nebra Sky Disc – which is the world’s oldest surviving map of the sky. The palaeobiologist Thomas Halliday looks even further back in deep time to reveal the Earth as it used to exist. In his new book Otherlands: A World in the Making he uses the latest technology and fossil records to examine ancient landscapes – from the mammoth steppe in Ice Age Alaska to the lush rainforests of Eocene Antarctica, with its colonies of giant penguins. While these distinct ecosystems appeared stable for millions of years, their disappearance is a reminder of the both the fragility and tenacity of the natural world.Change and survival are at the centre of the writer and ecologist, Rebecca Nesbit’s book, Tickets for the Ark. As the current rate of extinction starts to resemble the demise of the dinosaurs 65 million years ago, conservationists appear to be fighting a losing battle. Nesbit questions the motives behind what we fight to save, in an examination of what we should conserve and why.Producer: Katy Hickman

Forget the Victorians, the Georgian era is having its moment. Regencycore, a fashion style inspired by the Netflix period drama Bridgerton was shortlisted for Word of the Year 2021, and there will be more frocks and 18th century gossip when the television series returns in the Spring. In The Georgians the historian Penelope Corfield explores all aspects of 18th century life, from politics and empire to culture and society, science and industry. She tells Tom Sutcliffe that Britain at the time was often seen as both a sentimental and enlightened place, where frippery and satire sat side by side. Before the Industrial Revolution The Staffordshire potter Josiah Wedgwood exemplified the era’s entrepreneurial spirit. He was, according to Tristram Hunt’s biography, The Radical Potter, the Steve Jobs of the 18th century. His innovative designs and marketing strategies made his wares popular throughout the country and further afield, and he was instrumental in building the infrastructure to enable the region to flourish economically.What could today’s policies to ‘level up’ the regions learn from the 18th century, and Wedgwood’s championing of his home town. Professor Philip McCann is Chair in Urban and Regional Economics at the University of Sheffield. He argues that during the last century the system of localised finance was lost as the country became highly centralised. This has had a serious impact on poorer regions and smaller local firms, and today the UK has some of the worst regional inequality in the world.Producer: Katy Hickman / Natalia FernandezPhoto Credit: LIAM DANIEL/NETFLIX Bridgerton, Series 2 (L to R) Bessie Carter as Prudence Featherington, Polly Walker as Lady Portia Featherington, Harriet Cains as Philip

The award-winning poet Fiona Benson retells the Greek myth of the Minotaur, upending the legend of the dashing male hero slaying the monster in the labyrinth. In a series of poems in her new collection Ephemeron we hear from the bull-child’s mother – the betrayed and violated Pasiphae. Benson tells Helen Lewis she wanted to explore male and female desire, and the extraordinary cycles of violence and abuse of power in the Greek myths.The cultural historian Ivan Jablonka has taken his native France by storm with his history of Masculinity – From Patriarchy to Gender Justice, translated by Nathan Bracher. In it he asks what it means to be a good man? Using examples from the past he explores the origins and structure of male dominance. He argues that it’s time that men took more responsibility and fought harder for genuine equality. The political philosopher Nina Power is more circumspect about the demonisation of men, which she believes is now rampant in today’s society. In What Do Men Want, Power looks at what happens when men feel beleaguered and retreat to the ‘manosphere’, and she explores ways in which men and women can live together more harmoniously. The number of people living alone has increased over the last decade, but it’s still a path that goes against what society expects, according to the entrepreneur and Founder of the lifestyle magazine, About Time, Angelica Malin. She became single at the beginning of lockdown and has now brought together 30 women to explore what single womanhood means in the modern age, in Unattached. Producer: Katy Hickman

Modernism is a cultural and philosophical movement that emerged in the West during the late 19th and early 20th centuries. It’s a complex hydra-headed beast that was pervasive in the arts, but also spread through modern industrial societies influencing architecture and science. As part of a series of programmes on BBC Radio 3 and 4 celebrating modernism, Kirsty Wark presents an introduction to modernism – how and why did it arise at this time, and its legacy today. She is joined by the cultural historian Matthew Sweet who is presenting a 10-part series for BBC Radio 4 on a crucial year for modernism: 1922 – The Birth of Now. Suzanne Hobson, from Queen Mary University of London, is an expert on modernist literature, and examines the defining characteristics of the genre, while the musician Soweto Kinch discusses the impact of modernism on music, especially the development of jazz, and how it plays out today. While innovations in the arts including stream of consciousness, atonal music and abstract art are the headline acts for modernism the academic Charlotte Sleigh looks more closely at what was happening in the sciences, and how innovations in physics, psychology and technology changed the way people experienced the world.

Are we heading into an era of unending low-level conflict, of foreign interference and buying of influence? In The Weaponisation of Everything, the security expert Mark Galeotti argues that traditional warfare is on the wane, replaced by hybrid wars, disinformation, espionage and subversion. He tells Adam Rutherford that this 21st century way of war often goes unnoticed and can be dangerously destabilising, but it also offers opportunities for those who are able to take full advantage of this new armoury. The political philosopher Cécile Fabre explores the ethics of espionage and counterintelligence. In Spying Through a Glass Darkly she looks to answer a fundamental question: when is spying justified? In the context of war and foreign policy what actions are morally justified, and when? Fabre brings together philosophical arguments and historical examples to study the moral justification of state blackmail, mass surveillance, treason and bribery.How far are the subversive techniques discussed uniquely human? It’s a question the primatologist Kirsty Graham considers as she studies the way bonobos and chimpanzees communicate in the field. Her research has shown that both groups share not only the physical form of the gestures but many of the same meanings. Producer: Katy Hickman

The historian, writer and former politician Michael Ignatieff talks to Tom Sutcliffe about how consolation offers a way to survive the anguish and uncertainties of the 21st century. In his new book, On Consolation: Finding Solace in Dark Times, he looks at how works of literature – from the Psalms to Albert Camus and Anna Akhmatova – help increase hope and resilience. On Consolation will be Radio 4's Book of the Week from February 7th. Christopher Prendergast’s Living and Dying with Marcel Proust is the result of a lifetime’s reading of Proust’s masterpiece A la Récherche du Temps Perdu.

Andrew Marr talks to two of the leading scientists who were at the forefront of research into fighting the spread of Covid-19. Professor Teresa Lambe was one of the Principal Investigators overseeing the Oxford/ AstraZeneca vaccine programme. She co-designed the vaccine and led the pre-clinical studies, as well overseeing the impact on immunity. She will be taking part in this year’s Royal Institution Christmas Lectures (to be aired on BBC 4 at 8pm on 28th, 29th and 30th December), alongside Professor Catherine Noakes. As an engineer Noakes is one of a tiny number of specialists worldwide who study ventilation and the spread of airborne diseases. From the beginning of the pandemic she has been instrumental in providing advice on how the virus transmits and the best strategies to control its spread.Covid-19 is a respiratory disease and one of the books on this year’s Royal Society prize shortlist is at the centre of revived interest in how we breathe. James Nestor argues, in his book Breath, that humans have lost the ability to breathe correctly, with damaging consequences that reach beyond snoring, asthma and allergies. Drawing on ancient wisdom and the latest scientific studies Nestor highlights the huge benefits from breathing through your nose, rather than your mouth.Producer: Katy HickmanPhoto: Professor Catherine Noakes doing a demonstration at the Royal Institution Christmas Lectures 2021

The internationally renowned cellist Steven Isserlis talks to Andrew Marr about his companion guide to The Bach Cello Suites. Isserlis explores why Bach’s Six Suites have become some of the most cherished music, and how Bach takes the audience on a spiritual journey, from joy, through tragedy, to jubilation.Schubert’s heart-breaking song-cycle Winterreise tells of a young man’s desperate wanderings: the music and the poems creating images of fire and snow, of scalding and frozen tears. The baritone Benjamin Appl, accompanied by James Baillieu, stars in a new BBC film, Winter Journey, filmed in a tower on the snow-covered summit of the Julierpass in south-east Switzerland. An album of the music will be released in February.The composer and pianist Kate Whitley is also interested in the importance of place in music. But she has taken a different tack, eschewing the often rarefied atmosphere of concert halls, for the concrete heart of city centres. She runs The Multi-Storey Orchestra which performs in car parks around the UK.Producer: Katy HickmanPhoto copyright: Satoshi Aoyagi

What if virtual worlds become indistinguishable from the real one? In 1999 the science fiction film, The Matrix, depicted a dystopian future in which people are unknowingly trapped inside a simulated reality, run by intelligent machines. As the fourth film, The Matrix Resurrections, is about to be released, the writer Naomi Alderman considers the influence this movie franchise has had in the last two decades, and how far virtual reality has become part of everyday life. The philosopher, David J Chalmers, proposes that the Matrix scenario could be the future, but that rather than trapped, humanity can lead a meaningful life in virtual reality. Chalmers is one of the leading thinkers on consciousness. In his latest book, Reality+ he provocatively argues that VR is not escapism. And that we may even be living in a computer simulation already – and if that is true, it’s not so bad.Philippa Garety is Professor of Clinical Psychology at Kings College London and has been at the forefront of treatments for problems associated with psychosis, including hearing voices and hallucinations. She is currently working on innovative treatments using digital technology, including avatars and virtual reality, to alleviate suffering. In a clinical setting VR can be managed as a safe environment for patients who struggle in the real world, as a place they can confront and understand their delusions.

The acclaimed actor Kathryn Hunter plays all three witches in the forthcoming Hollywood adaptation of The Tragedy of Macbeth. The film is directed by Joel Coen and starring Denzel Washington and Frances McDormand as the central couple. Hunter tells Andrew Marr that she studied the witch hunts of the 17th century and was inspired by the ‘outcast women’ who survived and suffered. Her performance is rooted in something real, but also hints at something created in the mind of Macbeth. Claire Askew’s latest collection of poems, How To Burn A Woman, is a cauldron full of spells, power and love. It’s peopled with witches, outsiders, and women who stand out. It too traces historic atrocities and celebrates the lives of those accused of witchcraft. But it also looks at contemporary relationships, of love bordering on infatuation, and the feelings of loss, bitterness and isolation at the end of an affair.When peculiar things begin to happen in the frontier town of Springfield, Massachusetts in 1651, tensions rise and rumours spread of witches and heretics. What follows is a web of spite, paranoia and denunciation – a far cry from the English settlers’ dreams of love and liberty at the dawn of the New World. The historian Malcolm Gaskill retells this dark, real-life folktale of witch-hunting in The Ruin Of All Witches.Producer: Katy Hickman(Image: Kathryn Hunter as one of the witches in The Tragedy of Macbeth, courtesy of Apple TV+)
