After deaths in the US and bans around the world, how risky are e-cigarettes? In some countries, smokeless cigarettes are all the rage. In the UK, doctors say if smokers switch from tobacco to e-cigarettes, it will save lives. But in the US, where the authorities are investigating an outbreak of lung injury linked to vaping, they’re advising vapers to consider stopping. In India, Mexico and dozens of other countries, vaping is banned altogether. It’s a confused international picture. Vaping is still relatively new and scientists are still researching how harmful it may be in the long-term. What we do know is that every year, eight million people die worldwide as a consequence of smoking tobacco. What are the potential health risks associated with vaping? We’ll find out from our expert witnesses, who include a neuroscientist, a pulmonary critical care doctor and a professor of nicotine and tobacco studies.(A young woman smoking an electronic cigarette at the vape shop.

The far right conspiracy theory featuring child molesters and baby eaters may sound far-fetched, but the FBI names Q Anon in a report warning conspiracy theorists pose a growing threat of violence. So can we dismiss Q Anon? Q releases anonymous internet posts and claims to have a high level of security clearance in the US, signing messages with only ‘Q’. The cryptic posts apparently reveal that Trump is fighting a battle against the deep state and trying to take on an A list paedophile ring. The followers decode the messages and enjoy feeling part of an online community who have ‘insider knowledge’. There’s no evidence behind any of it. The worrying thing is, it’s not just an online community, some followers have taken real world action, turning up in the desert with guns to hunt for satanic child molesters and a murder suspect has appeared in court with a letter Q written on his palm. Recently, the site Q posts on has been shut down, but our expert witnesses say that doesn’t mean we can dismiss Q Anon.(Trump supporters with Q Anon posters at a 'Make America Great Again' rally in Tampa, Florida, 31 July 2018.

The world’s two biggest economies are fighting a trade war, European growth is slowing and global manufacturing data looks grim. Financial markets are flashing warning signs. It’s been a decade since the last global recession and in 2019 so far, the data has started to turn down. Are we on the verge of an economic meltdown? And what can countries do to avoid recession or reduce its impact when it comes?(A container ship being loaded in a harbour in Asia. Credit: Getty images)

It’s been almost 15 years since a successful campaign to erase the crushing debts of Africa’s poorest countries. Now, debt levels are again creeping up, thanks in part to a risky mix of easy credit and easy spending. We hear from a former Liberian cabinet minister, a Mozambican anti-corruption campaigner, an expert in Chinese financial flows to the continent and the World Bank’s chief economist for Africa.Presenter: Neal Razzell(Photo: Protestors call for debt relief in Durban, South Africa.

In the afternoon of August 20th this year, the sky over Brazil’s largest city, Sao Paulo turned dark. The cause of this premature night was the smoke from fires burning thousands of kilometres away in the Amazon rainforest. The scale of the fires caught the attention of the world, but the Amazon is one story among many. The global community has long worried about deforestation, five years ago nations agreed to work to halve global tree loss by 2020 and end it by 2030. This month, those targets were acknowledged to be missed. This week we investigate what tactics are being used to preserve forests around the world, and ask if any of them are effective.image: View of a burnt area of forest in Para state, Brazil, in the Amazon basin.

Bruce Springsteen is turning 70; rock’s gods are getting on. It’s not clear who’s there with electric guitars to replace them. Younger acts are failing to make hit singles. Veteran rock journalist Mark Coles believes rock music has lost its ability to surprise and innovate. Record label boss Vanessa Higgins describes how the writing of hit songs no longer favours the rock format. Music critic Michael Hann blames the high costs of making rock as part of the reason for its decline. But Chris Woltman, manager of the band Twenty One Pilots, believes bands have adapted rock for a new generation of fans and industry veteran Sat Bisla details how rock is making headway in non-traditional markets like India and Indonesia.

Quantum computers could transform our lives. Based on a branch of Physics that even Einstein found "spooky", the machines are still in their infancy. But governments and corporations are spending billions trying to turn them into workable technology. Neal Razzell finds out why by talking to four experts: Shohini Ghose, Professor of Physics and Computer Science at Wilfred Laurier University in Canada Stephanie Wehner, Professor in Quantum Information at Delft University of Technology in the Netherlands Winifried Hensinger, Professor or Quantum Technologies at the University of Sussex Jonathan Dowling, Professor of Theoretical Physics at the University of Louisiana and author of 'Quantum Technology - The Second Quantum Revolution' and 'Schrödinger's Killer App - Race to Build the World's First Quantum Computer'.Image: Professor Winfried Hensinger with a quantum computer prototype at the University of Sussex.

Fact-checkers say the President of the United States has made more than 10,000 false or misleading statements since coming to office. Whether it’s the size of the crowd at his inauguration, the pay rise offered to the military or where his father was born, Donald Trump often says things that are untrue. And he doesn’t rush to correct them, even when they’re outright fabrications. Ruth Alexander examines Donald Trump’s long record of falsehoods, which stretch back even to his schooldays. And she explores his motives, both political and psychological.Photo: US President Donald Trump addresses the press in the White House briefing room. Credit: Nicholas Kamm/Getty Images.

Porn, smart phones and the ‘slutty transmitter’. Adults in the US have sex on average about 50 times a year, which has dropped by 20 per cent over the last two decades. It’s a similar story in the UK, Australia, Germany, Finland and Japan. Could it be down to porn or our smart phones? Or is it actually down to something much harder to switch off? Some of the answers might surprise you.Picture: A couple in bed using their phones. Credit: Getty Images

It’s known for precision and punctuality but Europe’s engine is slowing down. Germany’s economy relies heavily on selling its products abroad. Famed for luxury cars like Porsche, BMW and Mercedes-Benz, exports are nearly half the German economy. So if countries decide they don’t want to buy, or can’t afford to buy, the things that Germany makes, it’s a problem. And that’s what’s been happening to Germany today. China – the most important market for most German car makers - is slowing down. Much of Europe is struggling and the US is pursuing its own protectionist policies, to get Americans to buy US-made goods. On top of that, the German car industry is facing tough new EU emissions tests (prompted by the Volkswagen emissions’ scandal of 2015), with crippling penalties if they don’t comply. So, buffeted by these adverse winds in part self-inflicted, in part beyond its control, the German government is being urged to boost its economy at home – by spending more on roads, bridges and broadband networks. But, as Neal Razzell discovers, despite having plenty of cash in the coffers, events in its past means Germany is reluctant to loosen the purse strings.Picture: German sports fan / Credit: Getty images
