Seriously...

The Berlin-based Argentinian artist, Tomás Saraceno, trained as an architect. He was struck by the beauty of spider webs, their structural intricacy and began making them into sculptural works. Then he realised that every time a spider tugs a string as it spins a web, or moves along the silken strands, this causes vibrations. Using microphones and amplifiers it is possible to hear the tiny music they make. The different species create various sounds - bass, treble, percussion - and the result is an orchestra of arachnids. On Air is Saraceno's latest and most ambitious exhibition. He has filled the Palais de Tokyo in Paris with extraordinary, beautifully lit spiders' webs, some connected to microphones so their occupant's movements echo round the gallery. There is an African spider that spins large webs which lift in the wind and so they travel, gliding places new. This inspires Saraceno's light-weight sculptures that do the same, and an aeolian harp of spider silk, which sings in response to the turbulence ca

The sounds of casting, chiming, singing and clanging are fused together to make a magical sound track to the story of how meat cleavers have been used as musical instruments for over 300 years.. Growing up in Suffolk, Nathaniel Mann, heard stories passed down by his grandma about a tradition of the village Rough Band, made up of pots and pans, iron and metal implements, including meat cleavers - delivering a sort of sonic warning to anyone stepping out of line, committing adultery or behaving in way considered unacceptable. As part of the Avant-Folk trio 'Dead Rat Orchestra', Mann, a singer and composer, has long been playing music with strange percussive instruments. Coming across an old meat cleaver in his dad's garage he was inspired to make a set of cleavers to play music on - so turned to a bronze bladesmith to help turn meat cleavers into musical gold. In a chance discovery, he discovered the idea wasn't new - and so he sought out Jeremy Barlow, author of “The Enraged Musician”, to find out the coded me

Artist Emma Critchley meets filmmakers, photographers, sculptors and painters who are drawn beneath the sea to create underwater art. Julie Gautier performs a graceful, lyrical ballet on the floor of the deepest pool in the world. Without a tank of air or mask, she dances magically through crystal-clear waters across a sunken stage. In the azure waters of the world, sculptor Jason deCaires Taylor uses the seabed as his canvas. He has installed hundreds of life-sized, concrete people on the sea floor. Fish weave through his couple playing on sea-saw, tourists taking photographs or migrants huddling in a raft. As Jason works towards the opening of his first cold water installation, Emma asks what draws him to the sea, the meaning of his work and how audiences can engage with underwater art. She explores the unpredictability of working with the sea, hearing stories of storms, seasickness and near drowning. Suzi Winstanley is petrified of the deep, but her passion for documenting wildlife has taken her to the rem

Laurie Taylor investigates the people who hear the voices of the dead in recorded sounds - and uncovers the strange and haunting world of auditory illusion. Believers in EVP, or Electronic Voice Phenomena think they're hearing the voices of the beyond - messages captured in the throb and static of white noise. Laurie Taylor's a rationalist - he doesn't go in for this mumbo-jumbo. But whilst the peculiar world of EVP may not be evidence of the afterlife, it does show how we're susceptible - far more susceptible than we might have ever believed - to be deceived by our ears. Laurie takes us on an mind-bending journey through the world of aural hallucination and illusion - revealing how the ghosthunters of EVP actually are showing off something rather profound about the flaws in our auditory perception...and they way we scrabble for meaning in the booming, buzzing confusion of the world around us. Contributors include the acclaimed expert on auditory illusion Diana Deutsch, writer and sound artist Joe Banks, neur

Alex Bellos is brilliant at all things mathematical, but even he can't hold a candle to the amazing mathematical feats of the supercalculators. Alex heads to Wolfsburg in Germany to meet the contestants at this year's Mental Calculation World Cup. These men and women are the fastest human number crunchers on the planet, able to multiply and divide large numbers with no need to reach for a smart phone, computer or calculator. So how do they do it, and is it a skill that any of us can learn? Alex talks to Robert Fountain, the UK's two-time winner of this prestigious prize, about his hopes for this year's competition and the mathematical magicians of the past who have inspired him. He also meets Rachel Riley, Countdown's number queen, to find out what it takes to beat the countdown clock.

Donald Trump's pledge to build a "big beautiful wall" along the US-Mexico border has inserted a political urgency into the mainstream art world and made the Latino experience a point of inspiration for many. Seven artists working on either side of the border wall, from the Pacific Ocean in the west to the Gulf of Mexico in the east, describe their work and how recent US immigration policy has helped to shape it. From music, to sculpture, virtual reality and performance art, the Art of Now explores the diverse artistic scene thriving along the 2000 miles border. Producer: Sarah Shebbeare

How instant noodles, now 60 years old, went from a shed in Japan to global success. What is the most traded legal item in US prisons? Instant Noodles. According to the World Instant Noodles Association, 270 million servings of instant noodles are eaten around the world every day. Annually, that's 16 to 17 portions for every man, woman and child. At the turn of the millennium, a Japanese poll found that "The Japanese believe that their best invention of the twentieth century was instant noodles." The Taiwanese-Japanese man who invented them (Momofuku Ando) was convinced that real peace would only come when people have enough to eat. In the bleak wreckage of post-war Japan, he spent a year in a backyard hut, creating the world's most successful industrial food. Crucially, he wanted the noodles to be ready to eat in less than three minutes. That convenience has since become a selling point for noodles that are consumed by students, travellers and, yes, prisoners the world over. Instant noodles first went on sale

The story of knife crime, told in verse by the weapon itself. Why do teenagers carry knives? How does it feel to live in a world where that's normal? How should we respond to the moral panic generated by the current wave of youth crime? Momtaza Mehri, Young People's Poet Laureate for London, presents a verse-journey into the thoughts and feelings of those for whom knife crime is an everyday reality. Perpetrator or victim, armed or defenceless, all the lines blur in "Ballad of the Blade" - a poem told in the voice of the knife as it travels on a chilling arc out of a child's bedroom, through fear, a yearning to belong and succeed, ruin and - sometimes - redemption. First-person voices from London and Sheffield splinter through the poem, reflecting the mosaic of lives affected by youth violence - bereaved youngsters and determined parents, criminals and youth workers. "Ballad of the Blade" is scored by Jon Nicholls. The programme was devised by Andrew Efah of BBC II! Producer Monica Whitlock.

The Sound Odyssey is a new series in which Gemma Cairney takes British artists for musical collaborations in different countries around the world, hearing the musicians in a new light, and exposing their artistic process as they create something new in different and unfamiliar surroundings with an artist they have never met before. In the first of a series of journeys Nadine Shah a British Muslim artist travels to Beirut, to collaborate with Lebanese singer songwriter and musicologist Youmna Saba. The challenge will be for them to create a track together in Beirut in just two days. Both have very different musical styles and cultural heritages. Nadine was born in Whitburn, South Tyneside, to an English mother of part-Norwegian ancestry and a Pakistani father. Her music is very much inspired by conflict, immigration, and cultural and religious identity, and her latest Mercury Prize nominated album, Holiday Destination was written about the Syrian refugee crisis. Although Nadine's lyrics have been very much ins

In February 2017, President Trump made a speech to his supporters. He moved on to the topic of immigration and Sweden. "You look at what's happening last night in Sweden," he told the crowd at a rally in Florida. "They took in large numbers; they're having problems like they never thought possible". This confused the Swedes because they hadn't noticed anything happening on that Friday night in their country. What Trump was referring to was a Fox News report he had seen about immigration and crime in Sweden. The report twisted a story done by Ruth Alexander for Radio 4's More or Less programme and used misleading statistics to try to show that recent immigrants were responsible for a crime wave in Sweden. More or Less debunked the report and its use of statistics but since then there has been spate of violent crime in Sweden. Ruth Alexander travels to Stockholm and Malmö to find out the truth about what's going on. Producer: Keith Moore.

According to Charles W. Eliot - President of Harvard and cousin of T.S. - everything required for a complete, liberal education could fit on a shelf of books just 5-feet in length. In 1909 the first volume of the Harvard Classics were published - and grew to become a 51-volume anthology of great works, including essays, poems and political treatises. But what if people today from all walks of life were asked to recommend books to be included on a five foot shelf? Which books do they think might be required for a complete home education? Ian Sansom has set a course for Wigtown - Scotland's National Booktown - to find out. Local craftsman Steve has been busy creating just the shelf for the job - exactly five foot long - and fashioned from elm wood and whiskey barrels recycled from a local distillery. Ian will be playing shopkeeper at the Open Book in Wigtown - a B&B meets bookshop which allows visitors to indulge their fantasy of running their own bookstore. With Ian parked behind the counter, all that's ne

If you are a parent, you probably do not need an introduction to Fortnite Battle Royale. It's the online video game that's been absorbing the minds and time of millions of children and young adults since its launch last September. To the uninitiated, it's an online shooter game that has elements of The Hunger Games movies and the building video game Minecraft. In each match, 100 people are air-dropped onto a cartoon-rendered island where they run around searching for weaponry, building defensive forts and fighting to the death. The winner is the last one standing. It's free to play on multiple devices from computers to games consoles to smartphones. Presenter Kevin Fong (medical doctor, broadcaster and father of two) asks, is Fornite more like the new crack cocaine or more like the Beatles? It's estimated that more than 125 million people have played Fortnite Battle Royale and that 3 million people around the world are playing it at any one time. Its creators Epic Games have earned more than US$1 billion from

The American satirist Joe Queenan goes in search of sovereignty. He wants to know what it is, what's it for, and how old it is "Now I know this is a big issue for you all right now. Over here we've been fighting over sovereignty since the eighties. The 1780s. But I still don't really understand what it is, nor why it's making everyone so mad."With contributions from Professor Richard Bourke, editor of Popular Sovereignty in Historical Perspective; and Edith Hall the author of Aristotle's Way: How Ancient Wisdom Can Change Your Life. The producer in Bristol is Miles Warde

Donegal is an Irish county where silence is a virtue. You can find it in the desolate landscape, the big skies and far horizons - but silence can be found in the people too. Maybe it's discretion or reticence. It could be shyness or a kind of wisdom.So when radical free-thinking commune, The Atlantis Foundation, set up home in the remote Donegal village of Burtonport in the mid-1970s, it seemed like an unlikely choice of location.Led by charismatic Englishwoman Jenny James and inspired by an experimental brand of counter-cultural psychology, the foundation practised 'primal scream' therapy. This was about letting it all out, yelling; shouting; shrieking to release deep rooted fears in the most challenging and visceral way. The locals simply called them the Screamers.Author and Donegal native Garrett Carr was a boy when he first heard of the Screamers. His family would lower their voices when mentioning them. While he found the name unnerving, Garrett was intrigued. On the coast near his home, he liked to imag

BBC political correspondent Chris Mason examines the changing accents of politics and politics of accents, with help from politicians, language experts and an impersonator.The programme examines the ways that stereotypes and prejudices can be loaded onto accents, how the voting public responds to different voices, and what politicians can do and have done about it all.With the help of the archive, the former Labour leader Neil Kinnock and former Conservative minister Edwina Currie reflect on the political soundtrack of their lifetimes. How have their voices, those of their contemporaries and the sound of the national political conversation changed?How is it possible and when it is sensible to change your accent? Chris is joined by Steve Nallon, who impersonated Lady Thatcher on Spitting Image, to listen back to her as a new backbencher and later as Prime Minister.And what about the sound of political reporting? The archive allows the former Today Programme presenter Jack Di Manio to give Chris (a son of the Y

Michael Sheen explores Aneurin Bevan's roots in Tredegar.A spectre is haunting Tredegar. It feels a little like that at least. This town high in the South Wales Valleys is understandably proud of its most famous son and makes the most of his memory.Aneurin Bevan was born in Tredegar in 1897. And he was the local MP there until his death in 1960. Memories of Bevan still populate the streets.Aneurin Bevan was a coalminer at the age of 13. He was a troublemaker with a stutter. An autodidact. He won a scholarship from his union for further study in London. He joined committees. He was a town councillor, then a district councillor, before reaching Westminster in 1929, where his greatest legacy must surely be his central role in the founding of the NHS in 1948. The civic religion of the NHS.And he fought for it in the image of Tredegar.It's perhaps ironic then, that it's in Aneurin Bevan's home town that the effect of the NHS was felt least of all.By that time an estimated 96% of the town's population was covered a

The writer and illustrator Judith Kerr has created some of our best-loved books for children since publishing her first, and perhaps most famous book, 'The Tiger Who Came to Tea', which celebrates its 50th birthday this year.Judith's life has always inspired her writing, from fleeing Nazi Germany as a child, a story she told in 'When Hitler Stole Pink Rabbit', to the peculiar family cats whose adventures she chronicled in the Mog series. Now 94 years old, Judith is still hard at work, still writing and drawing in the study overlooking the common where she has written all her books and in this programme Judith invites us into her study as she works on her latest classic.Producer & Presenter: Jessica Treen.

A convent of Mexican nuns is helping to save the one of the world's most endangered and most remarkable amphibians: the axolotl, a truly bizarre creature of serious scientific interest worldwide and an animal of deep-rooted cultural significance in Mexico.The Sisters of Immaculate Health rarely venture out of their monastery in the central Mexican town of Patzcuaro. Yet they have become the most adept and successful breeders of their local species of this aquatic salamander. Scientists marvel at their axolotl-breeding talents and are now working with them to save the animal from extinction. BBC News science correspondent Victoria Gill is allowed into the convent to discover at least some of the nun's secrets and explores why axolotls are a group of salamanders so important to protect from evolutionary oblivion.Axolotls are able to regrow lost limbs and other body parts. As a result, the aquatic salamanders are of great interest to researchers worldwide who study them in the hope of imitating the trick: to gro
