The Forum

This week, The Forum delves into the subterranean world of life underground – from the forgotten tunnels and catacombs of our cities to life found in the stifling sunless world two miles below the Earth’s surface. Might humans one day retreat underground if living above ground becomes too tough? Bridget Kendall with Social Geographer Dr. Bradley L. Garrett, Zoologist Dr. Gaetan Borgonie and Isotop...

As fire risks change due to climate change, how should we deal with fire to protect human health and property without compromising the integrity of our environment? Bridget Kendall asks the geologist Andrew Scott, the fire ecologist Jennifer Balch and the biologist David Bowman. (Photo: A fire tornado in California, USA. Credit: Getty Images)

Anxiety is a universal human emotion that has been described as the price-tag on freedom. It is the price we pay for a brain that can anticipate the future. But when anxiety spirals out of control it can take over our lives as we battle against phobias, panic attacks, dread and debilitating fear. So how is anxiety triggered and constructed in the brain? Is the almond-shaped amygdala the seat of fe...

Our lives are increasingly cluttered by images, not just in the world around us, but on advertising bill-boards, television screens, and even on our mobile phones. So how are we to process this barrage of information and make sense of the visual world? How can today’s designers help us and how are we to avoid image-overload? Bridget Kendall talks to three people who help us navigate the increasing...

A small toy balloon floating free into the sky. A giant hot air balloon filled with passengers peering down at the ground. Classic images, but what about the huge balloons now being developed to help us explore outer space? Or the tiny balloons which bio engineers inflate inside your body to help blood surge through your veins? Or the extraordinary balloonomania that spread across Northern Europe...

Everyone likes to be alone sometimes, but we also all spend much of our lives collaborating and sharing things with others. Many argue that on this increasingly crowded planet, we need to master the art of sharing much better if we are to survive and flourish. So what makes us want to share new ideas and pass on our experience? Bridget Kendall discusses three very kinds of sharing - digital inform...

New ideas about volcanoes, earthquakes and other geological processes that both enrich and threaten us.

If you think of your favourite foods – chocolate, maybe, or samosas, or pizza – do you really know where all the ingredients came from? Bridget Kendall asks the food scientist Chris Elliott, the software designer Jérôme Malavoy and the food labelling expert Monique Raats. Photo: The food label on a box of brownies (Getty Images)

One of the first things that comes to mind when thinking of radioactivity is often a nuclear accident or dangerous rays. But radioactivity is in fact a much more varied phenomenon, one that can bring us great benefits as well as put us in danger. With help from three experts, Rajan Datar looks for a more nuanced picture of the role radioactivity plays in our lives. Photo: A symbol for radioactivit...

Acts of defiance small or large have proved to be incredibly powerful throughout history, but when does defiance spill into aggression? Bridget Kendall asks the employment lawyer Lewis Maltby, the theatre director Olivier Py and the psychopathologist Dr Luna Muñoz Centifanti.

The Obama administration recently announced it will spend over a hundred million dollars on deepening our knowledge of the human microbiome - the bacteria, fungi, viruses and other organisms which make their home in and on our bodies. Bridget Kendall is joined by three people whose work in different ways enriches our appreciation of the world of human microbiota - the epidemiologist Mark Woolhouse...

We are at The Metropolitan Museum of Art in New York at The Met Breuer, where the exhibition "Unfinished: Thoughts Left Visible", is a springboard to explore the notion of things unfinished or incomplete. The concept of a work of art that is unfinished, the so called 'non finito' style, has been with us since the Renaissance. But it has taken on new meaning in modern art of the 20th and 21st Centu...

According to the United Nations, we probably throw away over one billion tonne of waste every year. Some goes into landfill, some is destroyed and some is recycled. The mountain of cast-off litter is not just a huge environmental challenge, but a logistical one as well. Bridget Kendall explores ideas about how to harness waste with - Martin Medina, a global waste consultant, who suggests scavengin...

These days everyone from schoolchildren to business owners is being told to become more resilient, but what does resilience mean in geological time? How and why do some organisms survive mass extinctions? And, on a shorter time-scale, how do people cope with the demands of dictators? Janina Ramirez and her guests discuss how to survive adversity across time and space. (Photo: Caiman crocodiles in...

What is the place of rivalry in human behaviour? What drives it? And where is the dividing line between competition as a positive force and one that wreaks havoc? Samira Ahmed discusses rivalry in sport, in cities and in our minds with psychologist Stephen Garcia, sport morality expert Maria Kavussanu and historian Philip Mansel. (Photo: The finish line at the men's 100 meters final at the Seoul O...

Dr Janina Ramirez explores our relationship with, and attitudes to, darkness and the night. From the beginning of humanity when night was a time to sleep and hide from predators, over millennia the night and darkness has gathered a multitude of myths and cultural references all around the world and is something we can exploit, or something we might fear. Dr Janina Ramirez examines the human perspe...

The Forum is in Cape Town, South Africa, as guests of The British Council at the Going Global Conference. As globalisation enables the transit and relocation of people ever more quickly and easily, what impact is there on countries who desperately need to keep their skilled labour and what are the issues that need addressing? With Quentin Cooper to discuss the Brain Drain is professor Olusola Oyew...

People have come up with the idea of the wheel many times and in different places, but what were the key turning points which led to mass transport and the miracle of modern logistics? Bridget Kendall discusses the still-unfolding story of the wheel with historian Richard Bulliet, logistics expert Jagjit Singh Srai and Cyr wheel dancer Valerie Inertie. (Photo: Wagon wheels and the view of Monument...

We all need rules - nature has them and we impose them on our communities in order to function; sometimes fairly and sometimes not- depending on your perspective. But just how important are rules and how do rules in nature affect our function as human beings? And how are our rules being used and interpreted by machines as artificial intelligence and deep learning evolve at enormous speed? Bridget...

Balance is essential. It stops us falling over or getting too cross and it stops machines failing catastrophically. There are also very fine balances present, more generally in nature and across the universe. But much of the World is not in exact and perpetual balance - it needs constant fine tuning. To help explore our latest understanding of balance in human beings, machines and music, Bridget K...

From the horrors of human suffering and plunder of ancient artefacts in war to the reshaping of musical traditions, we examine the notion of things lost and found. British journalist Julian Borger reflects on the unmasking of some of the most notorious Balkan war criminals, Iraqi archaeologist Dr Lamia al-Gailani Werr mourns the loss of ancient relics in modern conflict and American pianist Bruce...

Bestselling Turkish novelist Elif Shafak, Nick Bostrom from Oxford’s Future of Humanity Institute and Ann Phoenix from UCL's Institute of Education trace the evolution of 21st century identity with the BBC’s Jo Fidgen. Are technology and geopolitics conspiring to create a new type of human, unrecognisable to our forebears? Is ‘serial migration’ the new norm for transnational families and what effe...

Bridget Kendall explores extreme living and what it tells us, from human exploration to deep sea fish and synthetic biology. Bridget and her guests explore hot dry deserts and sub-zero polar ice, deep sea vents, salt heavy lakes, acid hot springs and outer space. NASA scientist Lynn Rothschild is a pioneer in the field of astrobiology, interested in probing the limits of life on earth, to better u...

Is the idea of a pristine landscape an illusion, given that over thousands of years human activity has almost everywhere left its mark? Bridget Kendall asks the gardener Gilly Drummond, the land artist Danae Stratou, the archaeobotanist Dorian Fuller, and the historian William Beinart. (Photo: Blenheim Palace Park where English landscape architect Capability Brown created a 150-acre lake and plant...
