The Inquiry

This week we’re looking at nothing less than the state of life on earth. The planet has seen mass extinctions before, periods of widespread and dramatic species loss. Some now fear human activity is driving another one: land cleared for farms, homes and roads; waters filled with pollution and emptied of fish; skies choked with gasses causing climate change. But does it add up to a mass extinction?...

Millions of us take a vitamin tablet every day - how did they become so popular? We follow the rise and rise of vitamins from their discovery just a century ago, to the multi-billion dollar market of today. The story of how the vitamin supplement entered our daily lives takes us from the targeted guilt-tripping of concerned mothers, to the use of vitamins as a weapon against the Nazis, via a plan...

#MeToo became viral following allegations of sexual harassment and violence at the hands of Harvey Weinstein. Now women and men in their millions around the world have been mobilised by the hashtag to share their stories of abuse. But its founder Tarana Burke fears the movement has moved away from its original remit to give a voice to victims of sexual violence. She worries it is being talked abou...

Journalists have been subject to more killings, and increasing levels of violence and intimidation in 2018, according to monitoring groups. This year alone more than 30 have been murdered, including Mexican veteran journalist Carlos Domínguez Rodríguez who was stabbed to death in January, 5 journalists shot dead at their office in Annapolis in the US in June, and the story that has dominated the n...

The UK voted to leave the European Union in June 2016. More than two years on, it’s still not clear how that will happen, or what will come after. Consensus within Westminster seems impossible, and if the deal currently on offer from Brussels is voted down on December 11, the UK could crash out of the EU with no deal at all. What makes it so hard to come up with a solution? The BBC has followed al...

There’s talk of a new Cold War between Russia and the West. What responsibility does the West carry for the dismal state of relations? Russian leaders say Nato has expanded far beyond the borders that were agreed when the Soviet Union collapsed and a new European order was thrashed out. They see troops and hardware stationed close to their towns and cities as highly provocative. America and the EU...

There are currently a number of serious allegations made in the West against Russia. They include the attempted murder of the former spy Sergei Skripal on British soil; interference in the 2016 US election; the hacking of the American electricity grid. To some, it feels like the West is under attack. But do any of these actions amount to war? Olga Khovostunova, a Russian media analyst, describes t...

There are different routes to pariah status. North Korea, with its gross human rights abuses and illicit nuclear weapons programme tops the list and represents the classic pariah - completely ostracized from the international system. Another sure-fire way to become a pariah is to sponsor international terrorism, like Muammar Gaddafi’s Libya in the 20th century. But as his example shows, internatio...

Warnings about the approaching post-antibiotics apocalypse have been sounding for years. There are now strains of deadly bacteria that are resistant to all antibiotics. This means that doctors are faced with patients who have completely untreatable infections. Hundreds of thousands of people worldwide are dying due to antibiotic resistance - and this number is set to rise rapidly. If we carry on l...

The burgeoning relationship between China and Africa has been one of the great economic stories of the 21st century. Billions of dollars of investment and loans from China have created radical change in many African countries. But not everyone is happy, with some even claiming this is a new form of colonialism. As signs of discontent grow in countries like Zambia, and investment numbers start to s...

Thousands died when an earthquake and tsunami struck Palu, Indonesia – but could more lives have been saved? Accusations have been made of a host of failings: alert systems that were out of action, sirens that didn’t sound, a government slow to give emergency help - even people who were too busy filming the disaster to run away. How much truth is there to this? Was everything done to warn people b...

Delhi is one of the worst polluted cities in the world. Radical ideas like skyscraper-sized air purifiers are being proposed to clean the smog – can they work? There are lessons to be learned from other cities around the world about how to manage emissions. But will any city’s air ever be really clean? (Image: A heavily polluted street in Delhi.

Most countries in the world have signed up to the idea that no child should work at all under a certain age – but is this the best approach? This week Nicolle, a 17 year old from Peru, has been part of a delegation of child labourers visiting the UN to ask them to rethink their ban on child labour. She’s been working since she was 8 years old, and says not only did her family need the money she ea...

DNA testing is big business. Millions of people worldwide are finding out about their ancestry and genetic health traits by sending off a spit sample to one of the big consumer genetic testing companies. But what do your genes really tell you? And could genetic testing have harmful consequences for our health and for society? Four experts chart the rise of consumer genetic testing and examine the...

The story of how a line on a map becomes a hard state border that no one can cross. Korea was ruled as one Kingdom for a thousand years. They valued poetry and scholars helped rule the country. But their Kingdom was invaded by Japan. When Japan left, Russia and America raced to take their place. Amid frantic organising, a line dividing Korea in two was suggested. Who knew that line would become th...

Ever since it began, women’s sport has been beset by a fundamental question: who gets to compete as a woman? It’s a debate which is more heated now than ever. That’s because in a few months, athletics’ governing body, the International Association of Athletics Federations, will introduce controversial new rules, regulating the participation of athletes with disorders of sexual development, commonl...

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...
