The Inquiry

Thousands of cyberattacks occur every single day. Some hackers steal credit card details or pilfer money from online bank accounts. Others cripple businesses, or even governments. As tensions mount in cyberspace, what are countries doing to strengthen their cyber power and build a hacking army? In this Inquiry, we delve into some of the world’s most intriguing cyber operations – including Iran, Ru...

It’s graduation day at the end of a religious summer school in Yemen’s Saada province. A class of young boys are off on a trip to a shrine. In a land of war, they are happy - jostling and full of energy on their school bus. Moments later, most of the boys are dead. A Saudi-led coalition airstrike has hit their bus. The bomb that was dropped by the Saudis was made in the United States, and Saudi Ar...

The year 2030 was set by the UN as the world's deadline for halting the spread of HIV, stopping Aids deaths, and having the first generation since 1980 born and raised completely free from infection. But at last month’s 22nd International Aids conference the mood was less optimistic. Deaths from the disease, having stabilised, are now beginning to increase, with some people fearing the disease is...

It was May 2013 when Cody Wilson went public with his 3D-printed handgun. An online video showed the crude plastic object fixed on top of a tripod. The trigger was pulled from a distance by someone pulling a long piece of string. Since that first successful firing, 3D printed guns and the debate around them has come a long way. The design for Cody Wilson’s plastic firearm, dubbed the ‘Liberator’ h...

In India, false rumours about child kidnappers, spread on WhatsApp, have prompted fearful mobs to kill innocent people. In May 2018 a video went viral. The original, a Pakistani child safety video, had been edited to show two men on a motorbike driving up to a group of children playing cricket in the street. They swoop up a small boy in a red t-shirt and drive away. As the video spread across Indi...

It’s a July morning in Ethiopia and Addisalem Hadigu, a journalist in his 50s, boards a flight to neighbouring Eritrea. But it’s no ordinary plane. This ‘bird of peace’ is the first commercial flight to operate between the two countries since 1998, and Addisalem is flying to see his wife and two daughters – the family he hasn’t seen in 20 years. Reunions like this are happening across Ethiopia and...

As relations with Iran and the West reach a new low point with the collapse earlier this year of the nuclear deal and the reintroduction of strict economic sanctions we ask: what does Iran think of the West? Pooneh Ghoddoosi explores a long and tortuous history of outside interference in the country. It dates back to the Western desire for Iran's rich oil reserves in the early 20th century, and co...

By the time she died at the age of 46, Koko the gorilla was a global superstar. Not only could she apparently understand two thousand words of spoken English and convey her own thoughts and feelings using sign language, but she was even able to give her own pet kitten a name. Some say that it’s impossible to know whether Koko really understood what she was communicating, or whether she was just tr...

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 repeat Inquiry – we’re looking at alternative climate-friendly diets and asking what it would take to move the world towards them. Presenter: Helena Merriman (Photo: Friends havin...

The world’s two biggest economies are on the brink of a costly standoff. The US has announced tariffs of 25% on a swathe of Chinese goods, starting July 6th. China has vowed to respond in kind. ‘If someone wants a trade war,’ China’s Commerce Minister said, ‘we will fight to the end.’ President Trump is bullish, threatening further tariffs and tweeting: ‘trade wars are good, and easy to win.’ But...

Donte Robinson and Rashon Nelson were waiting to meet a business associate in Starbucks. After two minutes, the store manager called the police and the African-American men were removed from the café in handcuffs. The Starbucks CEO has described the incident as “racial profiling”, claiming that the manager acted on unconscious racial bias. In response, he closed 8,000 branches of the coffee giant...

More than half the world’s countries are not producing enough babies to offset the number of deaths. Russia is the latest to experience a dip in the fertility rate, despite the government rolling out measures to encourage people to have more children. They have tried mortgage subsidies, giving couples days off to have sex, and rewarding fruitful mothers with the grand prize of a refrigerator. But...

Last year, the world watched as Islamic State was driven from Raqqa, the city they claimed as their capital. The UN has estimated that around 80% of the city’s buildings were destroyed or damaged in the battle. Eight months later, many Raqqans are returning home. Amid the rubble, life is slowly returning to Raqqa. This week, we investigate what life is like after Islamic State. (Picture: A view of...

Chicago resident Robert McDaniel was surprised when a police commander showed up at his home to warn him that they were watching him. With only a misdemeanour conviction and arrests for a number of suspected minor offenses, he had somehow made it onto the Chicago Police Department’s so called ‘heat list’ - a list of names created by algorithm of those deemed to be most at risk of either being a vi...

North Korea has been under sanctions for many years. But this isolated economy is showing signs of life that might surprise you. From hacking and counterfeit money to coffee shops in Pyongyang, we investigate what life is like in North Korea and how the state makes its money. Presenter: Celia Hatton Producer: Josephine Casserly (Photo: A woman shopping at the Kwangbok, or 'liberation', department...

Armenia's recent successful uprising is being celebrated as unprecedented for a former Soviet state. The so-called “velvet revolution” began on the last day in March with a protest walk. It ended two weeks and 100km later with the government overthrown. Yet revolutions rarely triumph. In this Inquiry we look at the factors that need to come together for such a revolution to succeed. Do they always...

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 wh...

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....

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 r...

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? (Photo: An African Elephant throws mud onto himself, Mpala Research...

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 secu...

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...

“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...

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 returni...
