Maintenance is an unfashionable word. But as Chris Bowlby discovers, keeping our infrastructure in good condition is one of the most crucial and creative challenges we face. Key assets such as concrete bridges built in the early post-war decades are crumbling, and may be what one expert calls 'ticking time bombs'. And all kinds of systems, even in the digital world, still need maintaining well. Bu...

For centuries we have met our other halves through family, friends, work, or religious institutions. But they have all now been outstripped: meeting online is now the most common way to meet. Not long ago, finding love online was considered unconventional. Now the ping of dating apps is the soundtrack to many people's lives. But what does this change mean for how we choose whom to date? Shahidha B...

Will the growing competition between China and the United States inevitably lead to military conflict? One leading American academic created huge attention when in 2017 he posed the idea of what he called a "Thucydides Trap". Drawing on the work of the ancient Greek historian, he warned that when a rising power (Sparta) threatens an existing power (Athens) they are destined to clash, unless both c...

Will human actions result in the demise of huge numbers of other species - in a mass die-off, comparable to the end of the era of the dinosaurs? Neal Razzell assesses the evidence that species are dying off at a rapid rate, and looks at some of the surprising things we might do to slow or reverse this process. Producers: Beth Sagar-Fenton and Josephine Casserley

What is the chance of the human race surviving the 21st century? There are many dangers – climate change for example, or nuclear war, or a pandemic, or planet Earth being hit by a giant asteroid. Around the world a number of research centres have sprung up to investigate and mitigate what’s called existential risk. How precarious is our civilisation and can we all play a part in preventing global...

Is there a better way to heal political divides - through panels of ordinary citizens? Sonia Sodha asks if the idea of citizens' assemblies, which have been used around the world to come up with solutions to polarising issues. Proponents argue that they avoid the risks of knee-jerk legislation, winner-takes-all outcomes or the pull of populism. Many in the Republic of Ireland believe that delibera...

Voters and politicians in Britain claim to be perplexed that economic and political relations between the UK and the Republic of Ireland seem to be decisive in determining the course of Brexit. They shouldn't be, argues Edward Stourton. A glance at the history of the countries' relations since the Acts of Union in 1800 helps to explain the situation. From at least the time of Catholic Emancipation...

Does a falling currency help or harm the economy? It's an urgent question for the UK, as the pound fell sharply in value against other major currencies after the referendum on Britain’s membership of the European Union in June 2016. Market commentators put this down to foreign investors becoming intensely gloomy about the prospects for the UK economy after Brexit. Others have welcomed the drop, sa...

Are we living in a ‘golden age’ of political conspiracy theories and what does belief in them tell us about voters and politicians? James Tilley, a professor of politics at the University of Oxford, talks to historians, psychologists and political scientists to ask why conspiracy theories are so common and who are the people spreading them. Why are so many of us drawn to the notion of shadowy forc...

Does being born to non-married parents affect a child's prospects? It is a question that is notoriously hard to answer. BBC Education Editor Branwen Jeffreys investigates research from Princeton's landmark Fragile Families study, which has gathered data from 5,000 births over the last 18 years. She speaks to principal investigator Professor Sara McLanahan to find out how much we know about the dif...

We live in a world where everyone is trying to manipulate everyone else, where social media has opened up the floodgates for a mayhem of influence. And the one thing all the new propagandists have in common is the idea that to really get to someone you have to not just spin or nudge or persuade them, but transform the way they think about the world, the language and concepts they have to make sens...

From a US president who is turning the world upside down – with a relish for dismantling global agreements – the message is clear: it’s America first. But where does that leave old European allies? Few expect the transatlantic relationship to go back to where it was before Trump. Europe, says Angela Merkel, now has to shape its own destiny. James Naughtie explores the uncertain future for America'...

Republican insider Ron Christie discovers how Donald Trump's presidency is changing his party. Trump arrived in the White House offering a populist revolt in America, promising to drain what he calls "the swamp that is Washington D.C". So what does his own Republican Party - traditionally a bastion of the nation’s establishment - really make of him? Where is he taking them and what will he leave b...

What could cause a future financial crash? Ian Goldin, professor of globalisation and development at Oxford University, talks to some of the world's leading economists about whether we have learnt lessons from the 2008 financial crash and whether countries are now better prepared to meet the next crisis. Or are we condemned to another economic meltdown, perhaps even more severe, which would provid...

Many key findings in psychological research are under question, as the results of some of its most well-known experiments – such as the marshmallow effect, ego depletion, stereotype threat and the Zimbardo Stanford Prison Experiment – have proved difficult or impossible to reproduce. This has affected numerous careers and led to bitter recriminations in the academic community. So can the insights...

How many democracies around the world are gradually being dismantled. Democracies today are less and less likely to be overthrown in violent coups. Today’s methods of establishing one party rule are much more subtle and insidious. Political scientist Professor Matt Qvortrup explores how the modern authoritarian leader takes control of his or her country. High on their list will be subtly manipulat...

Poison, exploding cigars and shooting down planes: tales of espionage and statesmanship. Government-ordered assassinations may seem the stuff of spy novels and movie scripts, but they seem to have entered the realm of reality of late. Why do states choose to take this action and can we measure their success? Edward Stourton assesses how various governments -including Israel, Russia, America and th...

How do you increase the attainment of disadvantaged children? Poorer children consistently perform worse at school by not reaching higher grades at age 16, compared to richer children. There is broad agreement, across party lines that they require more money to help them succeed and reduce inequality. Therefore, schools in England adopted the pupil premium policy in 2011 where extra funding was at...

Could Northern Ireland soon face a huge decision - whether to leave the UK? Andrea Catherwood returns to where she grew up to discover why the biggest question of all is looming beyond Brexit. Demography may soon leave Catholics as the largest population group. And Brexit debate over new border controls in Ireland has challenged the uneasy compromise of the Good Friday Agreement. So how could a vo...

Can the Conservatives ever win over non-white support? Black, Asian and minority ethnic communities are as diverse in their values and beliefs as the rest of the population, yet there is a history of ethnic minority voters overwhelmingly supporting the Labour Party. Recent studies show that in 2017 three quarters continued to back Labour, while under a fifth voted for the Conservatives. Long-term...

How power moved from West to East after the 2008 financial crisis. Ian Goldin, professor of globalisation and development at Oxford University, explores how Asian nations, especially China, demonstrated resilience, and rebounded quickly from the crisis. This led to a profound loss of faith in the ability of the Western leaders to manage the global economy effectively. Interviewees: Ngozi Okonjo-Iw...

Former homeless drug-addict Mark Johnson explores our relationship with street beggars

As well as marking the 70th anniversary of the National Health Service, this year marks a similar milestone in adult social care. But whereas our notions of fairness in treating those who fall ill are simple and straightforward - free to those who require care at the point of delivery in the NHS - with social care it is different: means testing remains the device by which assistance with care is d...

In 2016, during the American presidential election campaign, Edward Stourton travelled to the rustbelt of the United States to report on the new political power of Protectionism. Now, as Donald Trump seems poised for a trade war on two fronts - with China and Europe - he asks how far the American president will go to put "America First". Producer Smita Patel Editor Hugh Levinson.

Peter Pomerantsev asks why new techniques in political campaigning have succeeded and what the consequences are for society. He has a different view to most from his past career working inside the TV industry in Moscow. The future arrived first in Russia. The defeat of communism gave rise to political technologists who flourished in the vacuum left by the Cold War, developing a supple approach to...
