The Inquiry

Last year the US state of Texas introduced a controversial law designed to control the huge number of undocumented migrants crossing its southern border with Mexico. The law known as Senate Bill 4 or SB4, allows local and state police the power to arrest and charge people with a newly created state crime - ‘illegal entry’.

Immigration law has historically been handled by the federal government. Crossing the border is a federal crime and addressed by immigration courts that fall under the justice department.

Now Texas is embroiled in a legal battle and SB4 has been paused. But it’s just the latest measure that Texas has taken to stop hundreds of thousands of migrants entering the US on its border. Back in 2021 the state’s Governor, Greg Abbott launched a multi-billion dollar border security programme known as Operation Lone Star. Along with his Republican lawmakers, the Governor’s argument is that Texas has a legal right to defend itself and they allege that Democrat President Joe Biden has failed to secure the US southern border in violation of the law. But with a Presidential election this November, it remains to be seen if Texas will have a more sympathetic ally in the White House in the future.

So, on this week’s Inquiry, we’re asking ‘Can Texas go it alone on border control?’

Beyonce has released an album that has gone straight to the top of the country music charts.

The 27 tracks include the work of many collaborators from the world of country music, including Black country artist Linda Martell and Dolly Parton’s 1974 song Jolene.

It has been so well received it has become the fastest selling album of the year.

Beyonce is usually known for her pop and RnB. Her success in the country music genre has opened up a wider debate about where country music originates from, who it belongs to and its political associations.

This week on the Inquiry we are asking, who is country ?

An increasing number of people are dying from misuse of synthetic opioids. In 2022, the US recorded over 70,000 overdose deaths involving synthetic opioids. The government is spending billions to combat the effects of these super strength drugs. Synthetic opioids, such as Fentanyl, are made in laboratories by using materials derived from the opium poppy. China is a major hub for the production of synthetic opioids, where it then makes its way to North America through Mexican drug cartels.

The lab-made drugs can be more deadly than the natural materials, but they are more easily accessible, and prevalence is rising across the world.

In West Africa and the Middle East, tramadol is one of the most consumed synthetic drugs. The rise of synthetic opioids in the European market, which are being used as a substitute for a heroin shortage, is fuelling concern that these substances could lead to a rise in drug-related deaths.

This week on The Inquiry, we’re asking are synthetic opioids a global problem?

Six months into Israel’s war in Gaza and with no sign of a ceasefire or breakthrough in securing the release of the 130 hostages, as yet unaccounted for, pressure is mounting on Israel’s Prime Minister Benjamin Netanyahu.

There have been widespread protests in Tel Aviv and across Israel. There have been calls both from home and abroad for an early election to be called. And Israel’s greatest ally, the United States has sharpened its rhetoric in the past few weeks over Israel’s conduct of the war, with President Biden now saying that he believes Benjamin Netanyahu is making ‘a mistake’ in his handling of it.

For his part, the Israeli Prime Minister looks set to continue with his military offensive and has shown no indication so far that he is willing to step down or call an early election.

So, on this week’s Inquiry, we’re asking ‘How secure is Benjamin Netanyahu’s leadership?’

Not long ago, they were calling each other names and raising fears of a nuclear war. Now, it is feasible they could together win the Nobel Peace Prize - if they can reach a deal. The mooted meeting between America’s Donald Trump and North Korea’s Kim Jong Un could go wrong in many ways. Mr Trump has already talked of walking out. But in a spirit of optimism, this week’s Inquiry hears from those who have brokered some of the world’s most unlikely pacts for advice on how to strike the deal of a lifetime. With Helena Merriman.

In late December 2017, one of the world’s leading neurobiologists died of pancreatic cancer. His name was Ben Barres. He was an extraordinary scientist, advancing our understanding of how the brain works, in particular how certain cells in the brain may contribute to degenerative brain diseases like Alzheimer’s and Parkinson’s.

He had also lived the last 20 years of his life as a transgender man. He used his unique perspective of having ‘lived in the shoes of a woman and…the shoes of a man’ to become an outspoken opponent of gender bias.

As the voice of the transgender community continues to grow in influence, what can wider society learn from people who’ve been in this rare position of living life as both a perceived man and woman? What does their experience tell us about the nature of gender bias? And does it help us fix it?

Black infants in America are twice as likely to die in their first year as white infants. This stark disparity has long puzzled doctors and researchers. Why are so many African-American babies dying?

Syria, Salisbury, Malaysia Airport – all sites of nerve agent attacks carried out in the past couple of years. Yet hundreds of countries have supposedly destroyed their stockpiles of chemical weapons. It’s also illegal to produce and use them.

We look to four of the world’s most experienced chemists and researchers to tell us more about the nerve agents used in these recent attacks, how they are regulated and the ongoing problems of getting rid of them.

China’s ivory market is now closed for business. The country has long been one of the world's biggest consumers of ivory. But as of this year, buying and selling ivory in China is illegal. Carving factories, workshops and jewellers have all shut their doors. How did this happen? And will it be enough to save the African elephant?

When Robert Mugabe was deposed last year, he had ruled Zimbabwe for nearly four decades. How do dictators and authoritarians stay in power? James Tilley, a professor of politics at Oxford University in the UK, finds out what's in the dictators' survival guide. How do they control ordinary people and stop revolts? How do they stop rivals from taking over? And why are elections often helpful to securing their rule?

The tide of public opinion is turning on plastic.

The image of a whale with plastic stuck in its mouth on the BBC nature documentary Blue Planet 2 woke people up across the world to the reality of plastic pollution in our oceans. Experts think that by 2050, there could be more plastic than fish in the sea. Communities across the globe are saying that something must be done.

But does this change in public mood spell disaster for plastic? And if so, what would replace it? We go from Europe, to the US and Indonesia to examine the supply and demand of plastic.

“Humans are the only species that willingly deprive themselves from sleep”. Ever since fire was discovered, we have traded off sleep time for other activities - from creating stone tools to partying. As our technology progressed, the list of things to do rather than sleep just got longer. But with sleep deprivation now a growing health problem, could we be reaching our limits? Or is tiredness part of our condition? In this week’s programme, an evolutionary biologist, a historian and a neuroscientist give us their take on whether we are now any more tired than our ancestors. We hear what makes human sleep unique and how it has evolved in surprising ways. And finally we hear from a woman with a dream – that we may never have to sleep again.

Presenter: James Fletcher Producer: Estelle Doyle and Sarah Shebbeare

From courtrooms and prisons to rehab centres and martial arts training. We look to Europe, Iraq, Central Asia and Saudi Arabia to investigate how they are dealing with Islamic State militants.

The defeat of Islamic State in Iraq and Syria has raised a new, global challenge. While Iraq is funnelling huge numbers of Islamic State suspects through its courts, thousands of foreign fighters are returning to their home countries. What is happening to former IS fighters?

It is one of the largest, most profitable companies in the world, with billions of users, but more and more questions are being asked of Facebook. Accused of allowing the spread of fake news and hate speech, and of turning a blind eye to election meddling by Russia, Facebook is in the spotlight for the wrong reasons. Facebook’s founder and CEO, Mark Zuckerberg has committed himself to “fixing Facebook.”

With the help of experts in the field, in the US, India and Germany, we ask if Facebook really is in trouble.

The US and UK governments have accused Russia of orchestrating the most damaging cyber-attack in history. It caused billions of dollars’ worth of damage in over 60 countries. This programme tells the story of the attack as it unfolded across the globe. With the help of the world’s leading cyber security experts we take a forensic look at how the attack began, the extraordinary way in which it spread, and examine the international repercussions.

Women earn less than men in every country in the world.

Women are now more educated than ever before. But, on average, they don't take home the same in their pay packets. And laws against discrimination in the workplace haven't been enough to close the gap.

This inequality in wages has proven difficult to shift. Governments, employers and unions are struggling to find solutions to this stubborn and deep-rooted problem. How do you close the gender pay gap?

It is feared than in a few months’ time Cape Town could run out of water. The city is planning for so-called Day Zero when the supply is switched off and people will have to collect water rations. Cape Town is an extreme example of what is now a global phenomenon of water scarcity. We investigate how the city got so close to the brink, and whether there’s anything that other cities around the world can do to avoid a similar fate.

The Taliban have staged devastating attacks in the capital of Afghanistan, Kabul, in recent weeks. And a BBC study has discovered the group is active across the majority of the country – pushing beyond its traditional southern stronghold into eastern, western and northern parts. Seventeen years after the Taliban were toppled by a US-led invasion, it is clear the insurgent group has not been defeated. Why are the Taliban so resilient?

The story of how the search for a material to replace ivory changed our lives forever. In the 19th century a billiard ball company placed an advert in a newspaper offering $10,000 to anyone who could come up with a substitute for ivory. There was growing concern that companies were hunting elephants into extinction so they could use their ivory for billiard balls, buttons and umbrella handles. The story that follows takes us from explosive factories that often went up in smoke to the modern world we find ourselves in today. How did plastics go from being a saviour of the environment to a cause for concern? How did we get hooked on plastic?

China has long been keen to assert its authority in the South China Sea. In recent years, it has undertaken a huge programme of island-building to stake its claim to the region. Fiery Cross, once a tiny reef, is now a fortified airbase. And this is just one of China’s seven artificial islands in the Sea.

But China is not the only one. Bordered by seven states, many others also claim parts of the South China Sea as their own. Experts warn these hotly contested waters could be a flashpoint for conflict in 2018.

Why is the South China Sea so important to China?

The EU’s launched the ‘nuclear option’ against Poland, the first time it’s triggered the disciplinary measure in its history. They say recent changes to the legal system mean there is a serious threat to the rule of law and as a punishment, Poland could lose its voting rights in the European Union. The ruling party say this is an attack on Poland and that the EU should not be telling them what to do. The government says that actually their judiciary is threatened by the legacy of communism which is why they have made the legal reforms. They also say they’re being singled out by the EU for their refusal to take refugees, which they claim pose a threat to their country. If you believe the government, there are lots of threats to Poland, but what is actually being threatened and is there something far greater at stake? What is the greatest threat to Poland?

In 2017 the black flag of the Islamic State group flew in the southern Philippines as a mixture of local and foreign fighters attacked the Islamic City of Marawi.

While the government did eventually regain control, it took five months to break the siege and many terrorist leaders escaped during the fighting. It's led to fears that the extremist violence could spread.

In this Inquiry we investigate the long history of conflict which provided a fertile place for IS's Islamist ideas to grow, and ask how important the region is to IS now that they're retreating in the Middle East.

In 1994 a United Nations conference, backed by 173 countries, announced that ‘female genital mutilation’ was a “violation of basic rights and a major lifelong risk to women’s health”. Agreeing it should end, international agencies and charities quickly swung into action, and over the next two decades millions were spent on campaigns to eradicate the practise around the world. Today though, pricking or cutting of the genitalia still happens to an estimated 3 million girls a year in 30 countries, and some experts are saying we should rethink how we tackle it. In this episode of The Inquiry we talk to four expert witnesses, all with very different views on what the next steps should be.

This programme contains frank discussions of a physical and sexual nature.

Making sense of the digital currency and the ideology of its founders, fans and future.

In 2010 a developer spent 10,000 bitcoin to buy two pizzas. Seven and a half years later that was the equivalent of over $80m.

Bitcoin has been exploding in value throughout 2017 as more and more people buy into the idea of a digital currency. Traditional financial institutions have even begun to get involved. But far from a mainstream investment, Bitcoin started life as an idea from the radical cypherpunk movement, who wanted to use decentralised technologies as a way to disrupt governments and corporations.

In this edition of The Inquiry we trace the history and development of Bitcoin – and ask whether its future will stay true to its libertarian roots.

What next for North Korea? Kim Jong-un's nuclear ambitions and their global repercussions are explored in this special, extended edition of the programme.

After a year of repeated weapons testing by the secretive regime that’s sparked a war of words with the United States, Ruth Alexander brings together six expert witnesses to dive deep into the detail of what is one of the biggest geopolitical challenges of our time.

Their discussion examines North Korea’s weapons capability, the mind-set of its leader, the chance of war breaking out and the possibilities of finding a diplomatic solution.

Governing moon miners, asteroid hunters and space junk sounds pretty tricky, but we better get our act together. This year the majority of space launches included commercial enterprises. Space is no longer just the playground of governments but companies; companies that want to mine the moon for water that they could sell as rocket fuel, companies that want to mine the moon for helium -3 which could be sold and used as energy back on earth and companies that want to mine asteroids for platinum that they could sell for huge profits. But is this legal? The Outer Space Treaty, a set of laws written in the 1960s, says no state can conquer or own the moon or any other celestial body. So if you can’t own the moon, can you sell what you find on it? Perhaps it’s time for a new set of laws. So, how do we rule the universe?

There is a place on the internet where almost two billion of us regularly go – many of us, every day. Facebook: the social network which Mark Zuckerberg started in his university dorm room and which has grown, in a little over a decade, into one of the most valuable companies in the world. But what does Facebook’s lines of computer code do with the data we give it – and what could it do in the future? Just how powerful is Facebook's algorithm? The answer will surprise you.

Forty-two Americans die every day from an overdose involving painkilling prescription opioids. President Donald Trump recently declared the US opioid epidemic a national public health emergency. Yet in the world’s poorest countries, cancer patients and people recovering from major surgery often get no effective pain relief at all. Why is access to prescription painkillers so unequal? And is the shortage of opioids in much of the world getting the attention it deserves?

Missiles, fighter jets and mines waiting on the sea bed - war games in the gulf. Tension between Iran and Saudi Arabia is at an unprecedented level since a missile was intercepted over Saudi Arabia’s capital city. The Saudi Crown Prince blames Iran and says the attack may be considered an act of war. This is what would happen if they did go to war.

The world’s most profitable company is accused of aggressively dodging tax. Leaked documents in the Paradise Papers show Apple moved hundreds of billions of dollars in untaxed foreign profits to Jersey, where foreign companies pay no corporation tax. Yet Apple says it pays “every dollar it owes in every country around the world”. Confused? Not for long.

He’s pushed through reforms but some fear there is a darker desire driving the ruler. In one night, Crown Prince Mohammad bin Salman arrested over a dozen Princes and government ministers on corruption charges. To turn on his own royal family, he must be serious. But is corruption the Crown Prince’s real target or is this a power grab? There are also fears that the aggressive stance he has taken with Lebanon, Yemen and Qatar is increasing tensions with regional rival Iran. If the tension reaches a tipping point, there are fears the conflict could widen beyond the region. So what is he up to? What does the Saudi Crown Prince want?

Academic research stands accused of turning a blind eye to dodgy data, failing to reconcile contradictory findings and valuing money over knowledge. We examine the criticisms, which go the very heart of our pursuit of knowledge.

The growth and reach of a group labelled a ‘terror force’ by President Trump. On 13 October President Trump announced new sanctions against Iran’s Islamic Revolutionary Guard Corp for supporting terrorism. But what is the Revolutionary Guard and what is its role in Iran and the Middle East?

The group started as an army to protect the values of the Iranian revolution of 1979, but their role in fighting a long and brutal war with Iraq strengthened their military clout considerably. Today their forces work beyond their borders and have played a key role in the fight against so-called Islamic State. But they are no longer just an army, they run construction projects, run most of the telecommunications industry and even have a news agency. So how powerful is the Islamic Revolutionary Guard Corps?

Why internal conflicts end and what it might mean for Syria. The war in Syria is in its seventh year and there are few signs that an end is in sight. Yet over the years, other seemingly intractable civil conflicts have, eventually, been resolved. So, how did they do it and what lessons are there that might help Syria?

The head of the Roman Catholic Church has been accused of aiding the spread of heresy. A petition criticising the ambiguity of Pope Francis' statements on the treatment of people who have divorced and remarried is the latest twist in a fierce debate which is dividing Roman Catholics. The argument centres on whether divorcees on their second marriages should be able to receive Holy Communion, a ceremony that is central to the Christian faith. However, the dispute goes much deeper than that. At its heart, it is an argument over what it means to be a Roman Catholic and what the role of the Pope, and the Church, should be.

From driverless cars to "carebots", machines are entering the realm of right and wrong. Should an autonomous vehicle prioritise the lives of its passengers over pedestrians? Should a robot caring for an elderly woman respect her right to life ahead of her right to make her own decisions? And who gets to decide? The challenges facing artificial intelligence are not just technical, but moral - and raise hard questions about what it means to be human.

We all do it: ask a search engine things we wouldn’t dare ask a friend, post our lives on social media, hit the ‘agree’ button on privacy conditions we never read. This is life in our online age. To get our favourite apps and services for free, we provide companies with the intimate details of our lives. Businesses we’ve heard of, and many we haven’t, make money off this data in ways we may not fully realise. And almost every week it seems there’s another data breech – Equifax, Sonic, and Deloitte have been hacked in the last month alone. Each time the private data of millions of people is compromised. Can we control who knows what about us? And are we comfortable with how much information we’re giving up and how it might be used, or mis-used? This week the Inquiry asks “Is Privacy Dead?”

The list of nations legislating to ban the sale of petrol and diesel cars is growing. But these restrictions won’t come into effect for decades. Air pollution contributes to thousands of early deaths each year and the scandal known as Dieselgate, when vehicle manufacturers admitted tampering with emissions tests, made us more aware of the polluting power of the diesel engine. Automotive technology is advancing quickly, but will greener vehicles really replace the combustion engine? Hybrid and electric cars are better for the environment but more expensive, and petrol stations are easier to find than charging points.

This edition of the Inquiry asks, if we wanted to, could we ban the sale of diesel and petrol cars now?

North Korea continues to rattle the world with its rapidly advancing weapons programme. Diplomacy with this Hermit Kingdom is broken and UN sanctions have little effect curtailing the nuclear ambitions of the country’s enigmatic leader Kim Jong–Un. As its closest neighbour and biggest ally, can China solve the growing threat - with whatever options remain?

Do we have the power to avoid the natural forces of intense rainfall? With rising sea levels and the threat of climate change, the risk of death due to floods seems an insurmountable challenge. But there are some surprising facts in the figures on flood deaths. In developed countries like the US, more men die in floods than women and it is 30% of white men who are of particular concern.

We hear from four expert witnesses from across the globe, who share different options for change. Their ideas are both obvious as well as innovative, both low cost for use in developing countries like Bangladesh and high-tech like in the Netherlands. We also hear from the one place in the world which seems to be saving more lives in the face of devastating floods and storm surges than anywhere else on the planet.

Cemeteries around the world are fast running out of space. As more and more people choose to live in cities, some can't even cope with the ashes left after cremation. Deep questions about our communities, cultures and mortality emerge as The Inquiry asks: what can we do with our dead?

The programme script says that "only the very wealthiest can afford to rest in the ground in Hong Kong and Singapore". This is true for Hong Kong but Singapore's National Environment Agency has been in touch to say that you do not have to be wealthy to be buried in the government run cemetery.

North America’s most notorious racist group, the Ku Klux Klan fought the end of slavery in the 19th century, opposed civil rights in the 20th century and now forms part of a new extreme-right wing movement protesting openly, on America’s streets. Presented by James Fletcher and produced by Kate Lamble, The Inquiry asks four expert witnesses to answer this pressing question; how has the KKK managed to last so long? The answer can be found by looking at the origins of the KKK and the power of the white supremacist idea which became infamous for its’ distinctive costumes and deadly violence.

The American concept of freedom of speech has also helped give the KKK longevity. The views of the groups’ members are not shut down by the authorities. Rather, the KKK is allowed to speak and operate openly, within certain limits of the law. The hope is that counter protest and dialogue will expose the hatred and bigotry of its members.

Through hearing the views of one reformed racist, we learn how the group have been opportunistic in recruiting members. These include troubled young men, looking for family, security and meaning to their lives.

Finally, modern day technology has helped to spread the KKK’s message throughout the world via the internet. The group has been managed to mobilise and has recently, become emboldened by the election of President Donald Trump.

Video games are a huge industry, bigger than Hollywood, and billions of people around the world play them for fun. But new economic research in the US suggests that young men are dropping out of work to play games more. This is both because some jobs are becoming harder to find and less rewarding, and because video games are becoming more and more attractive. The gamers say they are happy, but the research has sharpened long-standing concerns about video games. Will there be a 'lost generation' of young men sitting in their parents' basements, frittering their lives away on mindless games, with disastrous long-term effects for them and the economy? Are video games a waste of time?

Smears, bots and bags of cash - we reveal some of the tricks used for fiddling elections around the world. German Chancellor Angela Merkel's security chiefs say Russian intelligence is actively trying to influence next month's German elections. Meanwhile, from the US to the Netherlands, countries are becoming increasingly wary of election interference. So how do you fix someone else’s election? Hear answers from people who've studied it and even been involved.

A story of crime and often no punishment. South Africa's notoriously violent record has been getting worse. The number of murders and violent crimes is rising as public confidence in the police falls. Officers themselves have been linked to a series of high-profile cases, including spectacular heists at the country's main international airport. South Africa's police minister has called for "a firmer, disciplined force". So, are South Africa's police failing?

You might think simple rules decide the creation of nation states. You'd be wrong.

There are plenty of people out there who want their own state - like in Iraqi Kurdistan and Catalonia, which both have independence referendums coming up. Yet the national governments in Baghdad and Madrid say the votes - whatever their outcome - won't result in new countries. So how do you start a new country? Making sense of an atlas dotted with exceptions, special cases and lands in limbo, we ask: who gets to have their own country?

Alarm about North Korea has spiked. Earlier this month, the North claimed to have successfully test-launched an intercontinental ballistic missile that could hit Alaska. Some experts estimate that North Korea is now 18 to 36 months away from launching a missile able to reach Los Angeles.

President Trump has warned that a "major, major conflict" with North Korea is possible. His closest advisers have said that "the era of strategic patience is over".

So, in this week's Inquiry, we take a look at the two sides' war plans and ask: what would war with North Korea look like?

Every single second, 20,000 single-use drinking bottles are sold around the world. That is more than a million pieces of non-biodegradable rubbish produced every minute. And as demand grows in developing economies, so will the mountains of waste, with much of it ending up in the ocean.

We learn how the invention of the plastic bottle spawned an industry that has quickly got us hooked. We hear the consequences of our addiction from the man who has dedicated his life to The Great Pacific Garbage Patch. And, with one estimate that by 2050 there will be more plastic in our oceans than fish, we ask if we now need a radical solution. Is it time to ban the plastic bottle?

"This structure has novel features, which are of considerable biological interest." It was perhaps the greatest understatement of all time - the announcement more than six decades ago of the discovery of the shape of a single human DNA. The double-helix structure is now one of the world's most recognisable icons. Knowledge of it has transformed the fight against everything from disease to crime.

That revolution was brought to us by an elite. It took the world's most eminent scientists, backed by the treasuries of the United States, the United Kingdom and private markets to go from the discovery of that one gene, in 1953, to map the more than 22,000 genes that make up a human being in 2000. Mapping the genome, as it was known, was likened to "learning the language in which God created life."

Genetic research has since become democratised. Incredible new technologies now allow labs all over the world to not only learn the language of creation, but to write it...and edit it. Do-it-yourself gene editing kits are available online for less than $100. Gene editing offers breathtaking promise - eliminating disability and disease. But the rapid spread of this powerful technology is leading some who've been at the forefront of the research to warn against unintended consequences, and question whether the rush for miracle cures could bring hellish side-effects.

So this week, The Inquiry asks, Is Gene Editing Out of Control?

The tiny state behind a global diplomatic feud.

Qatar's landmass is so small it could fit into the UK 20 times over. Its citizen population is just a few hundred thousand. Yet this desert country finds itself at the centre of a geopolitical dispute, with its powerful neighbour Saudi Arabia leading a blockade against it and President Donald Trump firing off critical Tweets.

So how did this bantam-weight state end up slogging it out with the world's heavyweights? In other words, what's so special about Qatar?

“Humans are the only species that willingly deprive themselves from sleep”. Ever since fire was discovered, we have traded off sleep time for other activities - from creating stone tools to partying. As our technology progressed, the list of things to do rather than sleep just got longer. But with sleep deprivation now a growing health problem, could we be reaching our limits? Or is tiredness part of our condition?

In this week’s programme, an evolutionary biologist, a historian and a neuroscientist give us their take on whether we are now any more tired than our ancestors. We hear what makes human sleep unique and how it has evolved in surprising ways. And finally we hear from a woman with a dream – that we may never have to sleep again.

China is currently developing the biggest infrastructure initiative of all time. Called the Belt and Road initiative, the trillion dollar plans involve working with other Asian countries to build hundreds of new roads, high speed trains, ports and pipelines across continent to mimic the ancient Silk Road trading routes. The project offers a clear economic opportunity, but the diplomatic ties that form as a result could have the potential to change the current world order.

On 12 June 2017 thousands of protesters took to the streets in over 160 towns and cities across Russia. Opposition leader Alexei Navalny called on people to march against corruption from Kaliningrad in the west to Yuzhno-Sakhalinsk in the east, in bustling cities and significantly, in rural towns where support for President Putin is strong. This is unusual. Protests are usually restricted to the urban elites in Moscow. So who is Navalny and how has he managed to bring so many people out on the streets?

Our expert witnesses assess the strength of the opposition movement in Russia. They explain that the protests reveal a greater threat to Putin. The mobilisation of a young generation who do not believe what they see on state TV and are turning to opposition politics online instead.

When violent jihadis struck London last Saturday, the rolling news networks kicked quickly into action. The story became front-page news around the world and dominated the UK's news media for days, with ever more information on the attack, the victims and the perpetrators. It was shocking, horrific - and perhaps also exactly what the terrorists wanted.

Terrorists rely on the world's media to spread their message of fear and their ideology. Maybe if there was less media coverage of such attacks, it would frustrate the people behind them. We look at four democratic countries where attempts have been made to limit the media impact of terrorism. Drawing on the lessons learnt, how do you report terrorism?

Many of us find our jobs stressful, underpaid and the hours too long. But few would complain about work being less physically strenuous than in the past. And yet, new research shows that the decline in physical activity at work is key to explaining the obesity epidemic. So - is work now too easy? And if it is, can this be reversed? Producers: Estelle Doyle and Phoebe Keane Presenter: Michael Blastland

Does the experience of poverty actually take a physical toll on your brain? The Inquiry investigates the scientific claims that being poor affects how our brains work.

It's well known that children from poorer backgrounds do worse at school. And adults who are poor are often criticised for making bad life decisions - ones that don't help them in the long-term.

Some say the problems are rooted in the unfair way our society functions. Others argue it's simple genetics. But a growing body of research suggests that something else may be going on too.

The Inquiry assesses the evidence and asks: does poverty change the way we think?

Brexit showed that the issue is now among the most important for British voters. And that’s likely to continue in June’s UK general election, as major parties have made their positions on immigration central to their campaigns. And yet for decades, immigration was a no-go area for mainstream debate. Following racial tensions in the 1960s, it came to be perceived as a proxy for racism. Today it is one of the most salient issues in British politics. What changed?

Once the richest country in South America, Venezuela is now in deep economic crisis.

Children in school are fainting from hunger; patients are dying from the lack of basic medicine. As prices spiral out of control, cash is carried not in wallets, but in backpacks. Street protests over the crisis are growing in size and frequency - and the government's response becoming ever more authoritarian.

Yet in 1970, Venezuela was among the wealthiest countries in the world. It was held up as a beacon of democracy and stability - an example of a successful developing economy that turned oil resource wealth into riches. So what went wrong? How did Venezuela go from so rich to so poor?

Tensions between the US and North Korea are running high. Kim Jong-Un has been testing long-range missiles and nuclear weapons. The Trump administration wants Pyongyang to end its nuclear weapons programmes and has said “all of our options are on the table” in pursuit of that goal. North Korea has said that a "super mighty pre-emptive strike” is planned if the US uses military force against them. But – our question this week – how did this poor and isolated country develop nuclear weapons in the first place?

Yuval Noah Harari, the author of Sapiens and Homo Deus, explores the long history of inequality – from the Stone Age onwards – and asks whether we are on the brink of creating a huge “economically useless” underclass, unable to keep up with enhanced humans, the owners of increasingly valuable data and, eventually, artificial intelligence.

There is a place on the internet where almost two billion of us regularly go – many of us, every day. Facebook: the social network which Mark Zuckerberg started in his university dorm room and which has grown, in a little over a decade, into one of the most valuable companies in the world. But what does Facebook’s lines of computer code do with the data we give it – and what could it do in the future? Just how powerful is Facebook's algorithm? The answer will surprise you.

In 2014 marijuana was legalised for recreational use in Colorado and Washington states in the US. Oregon, Alaska, California, Nevada and Massachusetts have all followed. These votes were the result of fierce campaigns. Activists argued that changing the law would eliminate the black market in marijuana; creating a legitimate, taxable industry and allowing the police to focus on more serious crime. Opponents feared more people would become cannabis addicts and predicted an uptick in health problems and robberies. So – three years in – what happened?

It’s two years since the start of the Saudi-led military campaign in support of the Yemeni government which was ousted by Houthi rebels. The war has been a disaster for countless civilians. Thousands have been killed and the country is on the brink of famine. The UN is calling it a humanitarian crisis. And yet it’s far from clear which – if any – of the multiple nations and groups involved in the conflict is working to end it. In other words, our question this week, why is no one trying to stop the war in Yemen?

At a recent press conference on the new US budget questions were asked about funding for climate change initiatives. The answer was stark. “We’re not spending money on that anymore,” reporters were told, they’re a “waste of your money”. The new administration is sceptical about man-made climate change. Most of the world’s scientists and governments, however, are not. The Paris Agreement committed the world to prevent global temperatures from rising more than two degrees over pre-industrial levels. That target looked close to impossible even before the election of Donald Trump. So – our question this week – do we need a ‘plan B’? Scientists have been developing some very ambitious ideas to re-engineer our climate. They have created materials that could suck carbon dioxide out of the air and a scheme to pump reflective particles into the atmosphere. But – if ‘plan A’ fails – might any of these last-ditch ideas actually work?

Every candidate in the upcoming presidential election in France is calling for change: change to the bureaucracy, the economy and even the culture. France, they say, is broken; society too divided, unemployment too high or the state too oppresive. Are they right? Is this call for change a tired political cliché – or a justifiable response to a deep set of problems? In other words – our question this week – what's wrong with France?

The UN has declared that South Sudan is in the grip of famine. Aid agencies have pointed the finger not at crop failure, weather or some other environmental problem. Humans, they say, have created this misery – misery which could easily have been avoided. The UN has also warned that conflicts in Yemen, Somalia and northeastern Nigeria mean there could soon be famine in those countries too, creating “the largest humanitarian crisis since the creation of the United Nations” in 1945. Humankind long ago figured out how to manage agriculture, store and distribute surplus produce or use trade to overcome hunger. So are all famines – like the one unfolding now in South Sudan – man-made? That’s our question on The Inquiry this week.

Mosul is today the scene of the largest battle on Earth. Some 100,000 soldiers, police and militiamen are bearing down on the ancient Iraqi city. Backed by Western air power, their mission is to drive out the so-called Islamic State fighters who’ve occupied the city since 2014. Mosul holds enormous symbolic value to both sides. The IS leader declared himself “caliph” there; the Iraqis want to avenge their defeat there nearly three years ago. Between them are hundreds of thousands of civilians. The UN says they face "extreme risks": water, food and fuel are already scarce. This edition of The Inquiry tells the story of the campaign and asks how the final phase could end.

Back in 2015 our radios and TV bulletins were full of stories of people trying to get to Europe. We saw distressing pictures as boats sank and lives were lost. Huge numbers of men, women and children tried to make their way by road, rail and foot to Hungary, Germany and beyond. There was anguish and fear in EU capitals. Now the story has slipped from the front pages. We find out what happened next.

Our phones are powerful tools with lots of benefits – keeping in touch, accessing information and services and managing our lives. We are using them more and more, constantly picking them up. Even in situations where it is considered inappropriate, disadvantageous, or even dangerous, many people still find it hard to resist the urge to check their smartphones. Why do we find these mini computers in our pockets so compelling?

Our expert witnesses explain how tech developers are tapping into established behavioural psychology theories about what gets us hooked. We hear how experiments conducted on pigeons can help explain why we cannot resist checking to see whether we have got email or a new like on social media and we reveal the tricks that companies use to keep us coming back for more.

President Trump has made no secret of his contempt for news organizations, stating that the media are "among the world's most dishonest people". He has described The New York Times as "failing", The Wall Street Journal as “a pile of garbage” and CNN as a “terrible organization” responsible for “fake news". The BBC? “There’s another beauty.” The President has made statements and assertions which are false. He uses Twitter to speak directly to the American people. His combative press secretary Sean Spicer said he plans to “hold the press accountable”. All this seems like bad news for what many Trump supporters call – derisively – the “mainstream media”. But might the opposite be true? Might Donald Trump, in fact, be good for journalism? That’s the question on The Inquiry this week.

Since 2006 the WikiLeaks website has been publishing secret documents and material obtained from whistleblowers and other sources. Many of the confidential files published by WikiLeaks have been revelatory. The site has frequently made news around the world. But in 2016 Wikileaks published hacked emails relating to Hillary Clinton and her presidential bid. Those leaks appeared to serve the interests of the Trump campaign and were – according to US intelligence – probably provided to Wikileaks by Russian sources. So, this week on The Inquiry, we’re asking: can you believe what you read on WikiLeaks?

"No deal is better than a bad deal." So said Britain's Prime Minister Theresa May, clarifying her country's position on Brexit negotiations with the EU. In the absence of a deal with the EU Britain would “revert to WTO rules” after Brexit. But what does that mean, exactly? The Inquiry has the answer.

'Do we want his finger anywhere near the button?' Hillary Clinton asked during the US election campaign, referring to Mr Trump and the nuclear arsenal. But how close is an American president's finger to 'the button'? How close is anyone’s? We explain how the nuclear weapons systems of the US, Russia, Britain and China work – and how much power any one individual has over them.

In 2002 US military personnel at Guantanamo Bay in Cuba were given 96 hours to prepare their sleepy base for the arrival of hundreds of prisoners. “The worst of the worst,” they were told. Beyond US jurisdiction, with no clear legal framework, prisoners accused of terror offences have been held there indefinitely without charge ever since. For many, Guantanamo has stained the image of the United States. When President Obama came to power in 2008 he vowed to close it. He failed. In this week’s Inquiry we are telling the full story of Guantanamo - from its creation to the so-called “forever prisoners” held there today.

It’s a question humans have asked forever. Are we alone in space? But it wasn’t until the late 1960s that humans started an organised, systematic hunt for extra-terrestrial intelligent life. We have listened to radio waves, peered through the celestial dust and beamed The Beatles to distant planets. So how’s it going? Is there anybody out there? This is the story of the search for extra-terrestrial life.

Food production accounts for as much global greenhouse gas emissions as all forms of transport combined. That’s why many scientists think we can’t tackle climate change without addressing what we eat. So – in this week’s Inquiry – we’re looking at alternative climate-friendly diets and asking what it would take to move the world towards them.

A lot has gone wrong this year. We are not talking about Brexit or the election of Donald Trump – both of which split opinion in Britain and the US. We are talking about terror attacks, the brutal conflict in Syria, and the thousands of migrants who died trying to reach Europe.

Good things did happen. But the good news was mostly buried under the bad. So we wanted to find about four things that went right in 2016. And, we talked to the people who made those things happen. Four amazing stories united by one thing - the ambition of a small number of extraordinary people to achieve the seemingly impossible.

It’s a surprisingly simple idea: to end long-term homelessness, give every person living on the streets a home. It can also be surprisingly effective. Medicine Hat, a city in Canada, recently became the first city to end homelessness in this way. The approach is known as Housing First, and – unlike many other homelessness initiatives – it doesn’t require homeless people to make steps towards solving other issues like alcoholism, mental health problems or drug addiction before they get a home. But is this approach solving the problem, or simply moving it off the streets?

We see and hear about Aleppo almost daily as news stories emerge of the hardship endured by its besieged people. After years of bombardment this once majestic place, the 'jewel' of Syria and one of the world's oldest inhabited cities, has been reduced to rubble. Thousands are dead. The residents who remain in the rebel-held parts of the city suffer from the ever-present threat of barrel bombs, while the international community has repeatedly failed to find a workable solution.

But why is Aleppo such an important part of the story of the war in Syria? The answer lies in Aleppo's historic role as a strategic city for so many people over the centuries, from Silk Road merchants of medieval times to the Assad regime and the forces currently battling for control of the country. Four Syrians, including one current Aleppo resident, tell us what life has been like in the city during its long and turbulent history.

Turkey first applied to join the European club over 50 years ago. Over the subsequent decades-long flirtation, enthusiasm for the EU in Turkey has remained high. Integrating with Europe, it was thought, would spur modernisation and economic development. But the country is changing under President Erdogan – who recently survived a coup attempt – in ways which deepen doubts in Europe about whether Turkey really shares its values. And enthusiasm in Turkey for the EU has begun to ebb away, as fewer and fewer Turks believe the EU will ever fully embrace them. So, our question this week: does Turkey still want to join the EU?

Trust in government is at an all-time low in many countries. From failed healthcare policies to missed intelligence, government blunders happen often – and visibly. But successful policy-making is hard (and fixes are rarely as quick as politicians like to promise).

Some argue that governments would do stupid things less often if they based their policies on the careful analysis of good evidence; find out what works, in other words, and then do that.

But that’s not how most governments operate, most of the time.

Why not?

Hillary Clinton lost the US election despite some polls putting her chances of winning at 99%.

In the run up to the vote pollsters spent huge sums of money speaking to thousands of Americans. They were careful to collect the best possible data from representative samples, and they applied their finest statistical minds to analysing the numbers. Yet almost no-one predicted that Donald Trump would win. So – our question this week – why did the polls get it so wrong? Our expert witnesses explain why polling is getting harder, and why many pollsters weren’t – despite that – very far wide of the mark.

Smoking tobacco is the single most dangerous voluntary activity in the world. It kills six million people a year, and if current trends continue that figure is expected to rise to 8 million people by 2030. Even if it does not kill you, it will give you bad breath, bad skin and cost you money. So why do so many of us still smoke?

On 8 November, as they stood in line to cast their votes, Americans were told by pollsters and pundits that, while close, the presidential race would be won by Hillary Clinton. As the results came in, precinct by precinct, many in the political establishment watched the unfolding story in disbelief. It was a similar feeling to that felt by many in Britain’s so-called ‘chattering class’ when, on June 24, they woke to the news that the UK had voted to leave the EU. Both were seismic political shocks. Neither was predicted by pollsters. What next? After two extraordinary electoral shocks, both of which challenge the established order, and with elections coming up in France and Germany, should we expect more?

The Clinton–Trump race has been extraordinary. Two of the most unpopular presidential candidates ever have slugged it out through a bitter campaign. They are both – for different reasons – deeply polarising figures. Hillary Clinton is viewed with suspicion by Americans who have turned against what they regard as “the elite”. Donald Trump has exploited crudely divisive, sexist, even racist, rhetoric. The tone of the contest has been ugly. But there is historical precedent for much of this – divisive policy positions on slavery or the famous attack ads of the 1960s. How should we view this campaign compared to the candidates, rhetoric, policies and media climate of past elections?

By 2050, experts predict that drug-resistant infections will kill one person every three seconds unless the world’s governments take drastic steps now. But given the complexity of antibiotics resistance, what should their plan be? Some of the possible fixes involve changing ingrained human behaviours such as doctors’ prescribing habits and the intensive farming of animals. But other promising solutions to avert a post-antibiotics apocalypse come from surprising sources. Scientists are now hunting for undiscovered fungi in the world’s most remote places while other researchers stay in the lab deciphering the language of bacteria.

The International Monetary Fund says corruption siphons $2 trillion a year out of the global economy, slowing growth and fuelling poverty. Endemic corruption is very hard to deal with. But not impossible. We tell the astonishing story of one country – Georgia – which did turn itself around. At the turn of the century Georgia was one of the most corrupt states in the world. Now it is one of the cleanest. How did it do it?

Earlier this year Europol, the EU's law enforcement agency, announced 10,000 children had arrived in Europe, part of the wave of migration that has swept through the continent in recent years. They had been registered and identified. And then they had disappeared. Many of these children are travelling alone. Some are as young as six years old. But the authorities across Europe – the police, the border agencies, NGOs and care organisations – have no idea where they have gone. They are at risk from trafficking and exploitation as well as the hazards of the journey across Europe – jumping onto lorries at Calais, sleeping rough in Northern European weather.

Under international and EU law children should be protected. There are various systems and regulations in place to deal with unaccompanied child migrants, whether refugees or not. But the system is failing and children continue to go missing at an alarming rate. Why?

So-called Islamic State is on the run. Caught in a pincer movement in Syria and Iraq, the group has lost large swathes of territory over the past year. With its revenues and numbers of fighters also dwindling, the demise of the caliphate appears all but unavoidable. And yet many caution against writing them off too soon, pointing to the group’s proven ability to change tactics. Already, they have redirected their efforts to launching terrorist operations around the world. And their ideology is still proving an effective recruiting sergeant.

The death of cash has been predicted many times over the years. But in the last decade a future without coins and notes has become a real possibility thanks to the global development and adoption of cashless systems. Some banks in Scandinavia are already refusing to accept or hand out cash. And, in nations with poor banking infrastructure, the growth of cashless has been explosive. Millions of people around the world now conduct their lives with hardly any cash at all and in terms of convenience, most of us are winners. But warnings are sounding about the driving forces behind this shift. Are we in danger of getting rid of our cash without really understanding the consequences? Presented by Linda Yueh.

It is now hard to find a country that does not have a state sponsored lottery – even the remote Himalayan kingdom of Bhutan recently adopted one. They have famously been called a “tax for people who are bad at maths” and make little economic sense for the individuals who play. Instead, lotteries allow governments to raise much needed revenue to be spent on ‘good causes.’ But there is more to lotteries than power-balls and million dollar prizes. Should we embrace them as a way of making life more fair? Presented by Michael Blastland.

Over the past eight months almost a quarter of the Great Barrier Reef has died – according to some estimates – because of coral bleaching, which can happen when sea temperatures rise. It's not the first time coral has bleached. It happened once or twice in the early 20th century after periods of warm weather. But, since the 1980s, coral bleaching has been happening regularly. And this year's Great Barrier Reef ‘bleaching event’ is the longest in history. Some say it signals the beginning of the end for coral reefs. There are though, rays of hope. In this Inquiry you'll hear from scientists who are pioneering some extraordinary ways of trying to help coral withstand warmer seas. They're hoping they're not already too late.

For millennia human beings worked until they dropped. Then in the late 19th century, Otto von Bismarck started the first state pension in Germany. The idea caught on. By the 20th century, advances in medicine meant that many more people were surviving childhood and living longer and longer into old age.

This was great news for those individuals, but not such good news for governments and companies who found themselves having to fund ever-longer retirements. Many of the most generous schemes have now been withdrawn and it’s increasingly up to the individual to save for their retirement – but many aren’t saving enough.

Volatile stock markets and low interest rates are making the situation worse. Many think retirement will turn out to be a "blip" in human history; it didn't exist in the past, and it won't exist in the future. So, is retirement over?

Our expert witnesses are: Professor Noel Whiteside of the University of Warwick, UK; Thomas B Jankowski, research director at Wayne State University, US; David Blake, director of the Pensions Institute at Cass Business School, London, Andrew Scott, professor of economics at London Business School.

Earlier this month 50 senior Republican national security officials signed a letter arguing that Donald Trump “lacks the character, values and experience” to lead the United States. “We are convinced”, they wrote, “he would be a dangerous president”. We want to know if they are right.

Our expert witnesses are: Timothy O’Brien, author of The Art of Being The Donald; Peter Feaman, Florida representative for the Republican National Committee; Daniel Drezner, professor of international politics at Tufts; and Elaine Kamarck from the Brookings Institution, an expert on presidential power and its limits.

The Olympic Games has a problem. In recent years the number of cities entering bids to host either the Winter or Summer Olympics has dropped dramatically. For the 2004 Summer Olympics, 12 cities bid. For the 2024 summer Games, there are only four cities running.

The 2022 Winter Olympics bidding cycle saw just two cities compete - winners Beijing, China and Almaty, Kazakhstan - after the other five cities that expressed an interest pulled out due to public and political opposition. And in cities that are hosting, the Olympics has been met with hostility.

Protesters tried to put out the Olympic torch in Rio, and in Tokyo public outcry at the cost of the stadium for 2020 has led to a complete redesign. Four expert witnesses pin-point exactly what is putting off potential host cities and discuss radical solutions.

The fighting in Ukraine has fallen off the front pages recently after making headline news in 2014. But Ukrainian forces and Russian-backed separatists are still engaged in a frozen conflict with no military or diplomatic solution in sight. Soldiers, rebels and civilians are dying. It looks good for Russia. Ukraine lacks the military power and international support to take back the East of the country where Russian-backed separatists hold huge swathes of land. And President Putin’s approval ratings at home have soared thanks to his annexation of Crimea in 2014. But does this mean Russia has won in Ukraine?

On 30 June this year, a study was released in one of the world's top scientific journals. It explained how a group of scientists who had been measuring the amount of ozone in the stratosphere had made a startling observation - the hole in the ozone layer had shrunk. Here, they said, was the first, clear evidence that the ozone layer had begun to heal. So how did this happen? It is a story that involves dogged scientific endeavour, the burgeoning green movement of the 1980s and the signing of what has been described as the most successful treaty ever created.

After more than 50 years of armed conflict that has left 200,000 dead and millions displaced, Colombia is on the brink of peace. A final deal between the government and the Farc guerrilla movement is expected to be signed soon. Thousands of armed fighters will then lay down their weapons in preparation for reintegration into a society from which they have been estranged for years. But the process will not be easy – for the Farc’s fighters, or for the rest of Colombian society.

“Brexit means Brexit,” says Theresa May, Britain’s new prime minister. It sounds pretty unequivocal: the UK voted in a referendum to leave the European Union, so that’s what it must do. But credible figures from US Secretary of State John Kerry to former prime minister Tony Blair have suggested that Brexit may not actually happen. Is that – legally, politically, democratically – possible? The Inquiry has the answer.
