The Inquiry

When President Obama wept at a recent press conference to announce action on gun control, his tears might have been born of frustration as well as sadness. Despite frequent mass-shootings, events which some might think would strengthen the case for tighter gun laws, it is difficult for any politician or party to change the rules on gun ownership in the US. One organisation is often credited with,...

The air in much of China is so bad the government has repeatedly declared "war" on it. The enemy are tiny particulates which spew forth from countless cars, coal-fired power stations and steel plants to create a dense, putty-coloured smog. Known as PM2.5s, after their length in micrometres, the particulates contain toxic droplets so small they embed deep in the lungs and sometimes even the bloodst...

Gender identity is considered more fluid than ever because of the success of the trans movement. But most trans people, just like everyone else, still identify as either a man or a women. For those who feel they are neither – or both – the male-female distinction does not fit. And, for the one in 2000 who are born with indeterminate sex, finding a place in this binary world can be damaging. So, ar...

The richest 10% of Americans earn half of all of income. In Britain, the top 10% hold 40% of all the income. Inequality is not just an issue for rich countries. A billion people have been lifted out of poverty since 1990, and inequality has been rising in many other countries too. So, how much inequality is too much? Many may recoil from such a question - inequality is a dirty word. But this progr...

The world has a problem. The climate is changing. At least, most people think so. That’s why global leaders have been meeting in Paris to work out a way to deal with the problem. They blame carbon dioxide in the atmosphere, much of it released by the human need for energy, obtained from fossil fuels like oil and coal. But believe it or not the world also has a solution at hand: sunlight. Harvest i...

The UN forecasts that the number of people living in Africa will double in the next 35 years. Nigeria, the fastest-growing nation, is expected to become the third-largest country in the world by 2050. By the end of the century, almost 40% of the world’s population will live on this one continent. It raises questions about how countries – some of which are already facing big challenges – will cope...

Many claim that ‘Islamic State’ is the ideological offspring of Saudi Arabia; that the strict form of Islam originating in the Kingdom - and the Saudi state's aggressive promotion of it around the world – has fostered terrorism. Saudi Arabia is also accused of funding IS, either directly or by failing to prevent private citizens from sending money to the group. But what is the evidence for these c...

Imagine waking up one morning to the sound of a helicopter overhead. You look out and see that packages are being dropped in front of the homes of everyone on your street. You race downstairs, and tear open your package. Inside? Exactly $10,000 in new bills. A gift of freshly-printed money from your government – no strings attached. What would you do? Economists hope you would go out and spend – a...

In November the US Drug Enforcement Administration issued its Drug Threat Assessment. Mexican ‘transnational criminal organisations’, it said, are the primary suppliers of heroin, cocaine, methamphetamine, and marijuana to the United States. Drugs – the DEA says – are killing 46,000 Americans a year. But between Mexico’s criminal enterprises, and their clients, is a vast expanse of difficult geogr...

We first asked this question over a year ago. So far, the answer has been no. The attacks in Paris killed 129 people. The day before that 43 people died when suicide bombers hit Beirut. Nearly two weeks before that a Russian passenger jet exploded over Egypt, killing all 224 people on board. The group calling itself Islamic State has claimed responsibility for all these attacks. If true, in two we...

New research suggests plants might be capable of more than many of us might expect. Some – controversially – even describe plants as “intelligent”, or even “sentient”. So, this week, we’re asking: have we underestimated plants? Our expert witnesses include an academic studying how networks of trees communicate through what she describes as a “wood wide web”, and the pioneer who is using plants to...

Syria’s cultural heritage is being attacked from all sides - the Assad regime, opportunistic looters, opposition forces, Islamic State fighters and even Russian air strikes. Ancient sites like Palmyra have been destroyed, and it is feared that hundreds of precious valuables have been smuggled out of the country to be sold on the international art market. Is it too late to save Syria’s antiquities?...

Mohammed Akhlaq’s murder shocked India. A mob broke into his house last month and beat him to death. They believed a rumour that Mr Akhlaq, a Muslim, had broken a Hindu taboo by slaughtering a cow. We find out how the cow became such a political animal and look at whether Hindu nationalists are feeling bolder in today’s India. (Photo: An Indian woman sprinkles yoghurt paste onto a cow's forehead....

Rhinos are in trouble. The ancient Sumatran rhino has just been declared extinct in Malaysia, following the fate of black rhinos in West Africa in 2011. Central Africa's northern white rhino has been reduced to four - yes, four - animals, and conservationists say the more plentiful southern white rhinos are under unprecedented attack from poachers eager to sell the horns to Asian and Arab buyers....

Oil accounts for around 75% of Nigeria’s economy, but no-one knows how much the country produces or refines. It means corruption is rife. Hundreds of thousands of barrels of oil are stolen every day, at each level of the supply chain. It is a problem that has cost the Nigerian economy billions of dollars, and weakened its public services and infrastructure. Schools and hospitals are paid for, but...

Russia’s intervention in Syria caught the world by surprise. Moscow gave Washington just one hour’s notice before it began its aerial bombardment. Russia claims its jets are attacking the so-called Islamic State. But reports suggest the Russian pilots are in fact targeting groups linked to the Free Syrian Army - the main opposition to Syria’s President Assad, who is a Russian ally. It is the first...

The CIA has just released 2,500 top secret presidential briefings from the 1960s. The President’s Daily Brief – or PDB – is the US intelligence agencies’ best assessment of global threats, delivered directly to the president every morning. The CIA’s director, John Brennan, has described the PDB as “among the most sensitive and classified documents in all of our government”. The decision to release...

The United States, UK, Israel and now Pakistan all use drone strikes to kill. In September a general in the Pakistani army announced their first ever use of an armed drone. It was directed at a terrorist compound, he said, and killed three. Meanwhile the US is thought to have launched a secret drone campaign to kill so-called Islamic State fighters in Syria. Armed drones are the counter-terrorism...

Japan is a pacifist country - at least that is what its constitution says. The wording, introduced under the occupying forces after World War Two, seems unequivocal: “the Japanese people forever renounce war as a sovereign right of the nation”. But new laws championed by conservative prime minister Shinzo Abe introduce a broader interpretation of what the constitution does, and does not, permit. A...

Tens of thousands of people have marched in Buenos Aires and elsewhere in outrage at the astonishing frequency with which women are being killed in Argentina - the vast majority at the hands of their partners or former partners. Violence directed at women and girls is at the extreme end of the scale. But the protesters believe it grows out of the 'machista' culture - where men have to be macho, an...

In 2011, following a devastating tsunami, Japan’s Fukushima nuclear power station went into meltdown, leaking radiation. It was the most serious nuclear accident since Chernobyl. It appeared to send the nuclear power industry into retreat – and not just in Japan. Other nations had second thoughts too. Germany decided to phase out its nuclear reactors altogether. But now Japan has resumed nuclear p...

Tens of thousands of migrants continue to queue at the borders of the European Union in search of a better life. Their journeys are often hazardous and thousands have drowned in the Mediterranean trying to reach Italy or Greece. Attempts to share the burden among EU member states have been dogged by internal politics. And Europe’s actions so far have focussed on deterrence despite little evidence...

Robots are coming for your job. Blue-collar jobs in industries like manufacturing have been disappearing for years but now white-collar work is under threat too. Machines are already taking roles that used to be done by journalists, lawyers and even anaesthetists. One recent study calculated that 47% of total employment in the US is at risk of automation in the next 20 years. So what will happen t...

In June last year the world's attention became fixed on the progress of so-called Islamic State, or IS. They had just captured Mosul, Iraq's second-largest city. Since then a reported 20,000 fighters from all over the world have joined them. They have killed and enslaved thousands. They have captured towns, oil fields and dams. They control vast swathes of Iraq and Syria. IS are more brutal, sophi...
