After becoming the most downloaded non-gaming app earlier this year, Telegram messaging app has amassed half a billion users – a quarter of WhatsApp’s and rising. Owned by the elusive Russian exile Pavel Durov, Telegram has been used to coordinate global protest movements - from Belarus to Iran and Hong Kong. It’s also been accused of tolerating the extremist channels behind ISIS and the Capitol Hill riots. But in its home country, Russia, misogyny appears to be permitted on the platform. Ivana Davidovic hears from women who worried for their safety when their personal information, including addresses and workplace details, were posted on Telegram channels, subjecting them to threats. Professor Megan Squire from Elon University in the US tells how she also received threats following her research into far-right groups on the platform, and about her fears that those groups might only get bigger if Telegram proceeds with plans to pay content creators.Digital security expert Raphael Mimoun looks under the app’s bonnet, explaining whether its privacy promises to users are up to scratch. And journalist Max Seddon profiles the founder and CEO Pavel Durov.

Voters in Greenland have backed a party which opposes a rare earth mining project. On Business Weekly, we ask what this means for the security of the global supply of rare minerals and hear why this project was so controversial. From the ice to the ocean, where the race to extract minerals is on. But environmentalists are concerned that deep sea mining could hurt the world’s oceans, even if they are being mined to help the environment in other ways. You may have heard of the term non-fungible token, but do you know what they are and how they work? We look at whether they are just another crypto craze or an amazing financial opportunity for digital artists. Plus, how to learn the art of complaining. The show is presented by Lucy Burton and produced by Matthew Davies.

After the Ever Given blocked the Suez Canal last month, we ask: are container ships too big? How much bigger can they get? To answer those questions we speak to Aslak Ross, head of marine standards at the world’s largest container shipping line, Maersk. Jan Hoffman, head of trade and logistics at the UN's Conference on Trade and Development, explains that economies of scale have led to the ships getting bigger and bigger. And Evert Lataire, head of maritime technology at Ghent University, describes how he assesses whether a mega ship can fit into a port, or through a canal.

How rocks on the ocean floor could be key to the transition to electric cars. Justin Rowlatt speaks to Gerard Barron, boss of DeepGreen, a company that wants to gather rocks from the ocean floors rich in the metals essential for making electric car batteries. He tells us why this kind of mining is crucial to transitioning away from fossil fuels. Louisa Casson, senior campaigner with Greenpeace, warns of the environmental devastation this could cause. And zoologist Adrian Glover tells us how mining could take place alongside conservation of the deep seabed. (Photo: A sunset over an ocean, Credit: Getty Images)

Can technology help eradicate forced labour from global cotton supplies? A confrontation continues to rise between Western powers, global brands, and the Chinese authorities over the use of forced labour and human rights abuse in cotton production in the western region of Xinjiang. Sophie Richardson, China director at Human Rights Watch, explains why transparency from the Chinese authorities over the whole cotton supply chain is unlikely to be forthcoming. With that in mind, some technology companies are volunteering their services to mark or trace the DNA of cotton, so apparel companies can be sure that it's not from a region with suspected forced labour. Jim Hayward, CEO of Applied DNA Sciences, explains how their particular cotton tagging technology works. But John Gapper, business columnist at the Financial Times, cautions that without larger industry willingness to uproot their business models, at considerable cost, the tech can only go so far to solve the problem.Presenter: Tamasin Ford Producer: Frey Lindsay(Picture: Cotton from fields in Xinjiang, China is displayed in the palm of a cotton-picker's hand.

When the world of crypto currencies met with the world of art, they created what's called a non-fungible tokens or NFT. Some say NFTs could redefine what we think of as art while others think it’s just the latest crypto craze that may well end in financial losses and tears.

How exposing the truth at work can cost you your career. Theo Leggett speaks to whistleblowers Ian Foxley and Bianca Goodson, both of whom found it impossible to get a new job after exposing wrongdoing at their respective employers. Psychotherapist David Morgan describes the emotional toll on those who choose to expose wrongdoing, and why the majority stay silent. And whistleblower lawyer Mary Inman, partner at the law firm Constantine Cannon, argues that companies need to start seeing whistleblowing as a help rather than a threat.

Josephine is a single mother of four in Kibera, the sprawling slum in Nairobi, Kenya. At the beginning of the pandemic she was working as a cook, but soon, like many Kibera residents, lost her job, and when the BBC's Ed Butler spoke to her a year ago her situation was dire. In this final episode in the series, Josephine looks to the future, and how she might retrain herself to find new ways to put food on the table. We’ll also hear from Kibera community organiser Kennedy Odede, how Josephine’s is just one of thousands of stories in the township. Dr John Nkengasong, head of the Africa Centres for Disease Control and Prevention, tells us of his concerns about East Africa’s ability to recover from the virus, given the unequal rollout of vaccines. But Kennedy Odede says we should not underestimate the resilience of Kibera residents.Producer: Frey Lindsay.Special thanks to Henix Obuchunju of Pamoja FM in Nairobi.(Picture: Josephine and her family.

Why do so many women still feel unsafe walking the streets of our cities? We take a look at the idea of a feminist city. What is it and what could it look like? And where in the world are they getting it right? Since the murder of Sarah Everard in South London in March, women all over the UK took to social media to discuss their experiences of walking the streets. And the lengths they go to stay safe. The 33 year old was walking home from a friend’s house in the evening she was murdered. The killing touched women all over the country - and even further afield. But what if women didn’t fear being out on the streets? Tamasin Ford speaks to Leslie Kern, the author of Feminist City: Claiming Space in a Man-Made World and to Sara Ortiz Escalante, a member of Col·lectiu Punt 6 (Collective Point 6), a cooperative of architects, sociologists in Barcelona in Spain who have worked in more than 120 towns and cities around the world with just one aim in mind - to put a feminist perspective on everything they do. Plus she speaks to Ellen Woodsworth, the co-chair and founder of Women Transforming Cities International in Canada, an organisation aimed at making cities better places to live for women and girls.

In February a devastating flash flood in India's northern state of Uttarakhand killed at least 70 people and trapped workers in underground tunnels. We'll hear from locals who witnessed the horrific events, as well as Uttarakhand journalist Kavita Upadhyay about how the news spread among the community. Indian geologist Dr Kalachand Sain explains exactly what happened that caused the flood, and Dave Petley, professor of geography at the University of Sheffield explains how climate change played a role. Now, in the wake of the disaster, India's strategy to bring more clean energy to the country through hydroelectric dams is coming into focus, with fears the projects are affecting the delicate balance of the Himalayan ecology. Himanshu Thakkar, coordinator of the South Asia Network on Dams, Rivers and People, explains why the dams should not have been near Himalayan glaciers to begin with,and what could have been done better to warn those near the disaster. Sunita Narain, director of the Centre of Science and Environment in Delhi argues, however, that development is needed in the Himalayas but it needs to be done responsibly. And we close with Amitabh Pande, who warns that the Himalayas are a precious resource to India, and should be treated with care.(Picture: the entrance of Tapovan tunnel following a flash flood in Uttarakhand state, India.

An EU ban on the vegetable oil's use in biofuel has upset Indonesia and Malaysia. Meanwhile critics say it will only worsen the problem of tropical deforestation by palm oil farmers.Manuela Saragosa looks at this most divisive of commodities, and moves to ban it impact the smallholder farmers behind almost half of global production. Sustainability researcher Gernot Klepper of the Kiel Institute explains why he thinks the European position is irrational, while Indonesian palm trade journalist Bhimanto Suwastoyo says palm growers could simply switch to markets in India and China where buyers care much less about deforestation.Meanwhile Greenpeace's Grant Rosoman explains why the environmentalist group is so sceptical about existing certification schemes, while Tiur Rumondang of the Roundtable for Sustainable Palm Oil - the biggest such scheme - defends their work.Producers: Laurence Knight, Joshua Thorpe(Picture: A farmer carries palm oil fruit at a plantation in Malaysia; Credit: STR/AFP/GettyImages)

A letter sent to the Bangladeshi government suggests that Beijing may be clamping down on the biggest source of carbon emissions.Justin Rowlatt speaks to the journalist who got the scoop - Jagaran Chakma of the Daily Star newspaper in Bangladesh. His nation is one of dozens of developing countries that need to build up their power sector, and had been looking to China to finance new coal-fired power stations under the Belt and Road initiative - something the letter pointedly said that Beijing would no longer do.So could China be preparing to take a much harder line against coal than advertised - at home as well as abroad? And what does it all mean for the big Cop 26 climate negotiations due later this year? Justin speaks to researcher Rebecca Ray of Boston University, former Australian Prime Minister Kevin Rudd, and former United Nations climate negotiator Christiana Figueres.Producers: Szu Ping Chan; Laurence Knight(Picture: Street vendors and customers gather at a local market outside a state owned coal fired power plant in Huainan, China; Credit: Kevin Frayer/Getty Images)

As rows continue in Europe over the safety and supply of the Oxford AstraZeneca Covid 19 Vaccine, on Business Weekly we ask how much of the argument is over genuine safety concerns and how much is political? We also take a look at the pandemic within a pandemic: obesity. It’s the second highest risk factor for Covid mortality. But, how much of the blame should lie at the door of the food industry? Will a renewed focus on health change what we eat and drink? Plus, governments around the world are trying to build back better and greener from the Coronavirus pandemic. We have a special report on the steel industry, which is being pressured to become more environmentally friendly. And the Oscars are #notsowhite this year – we take a look at the nominees.

Why is it that the boss never seems to know what they’re doing? The famous “Dilbert principle” asserts that companies promote incompetent employees into middle management to get them out of the way. But Professor David Dunning, co-creator of the competing “Dunning–Kruger effect”, says there’s more to it than that, specifically that the more incompetent a person is, the more confident they can be. Meanwhile, Kelly Shue, Professor of Finance at Yale, says an even simpler idea, the “Peter Principle” helps to explain why people get promoted beyond their level of competence. And entrepreneur Heather McGregor explains why the incompetence of a former boss led her to buy her own company Presented by Ed Butler, This is a repeat of a programme first broadcast in June 2020.(Picture: A woman at her desk.

The coronavirus pandemic has changed the way we behave on the internet. Online trolling is on the rise as people turn to social media to take out their lockdown frustrations.Marie Keyworth hears from Lisa Forte, who used to work for the UK police's Cyber Crime Unit and has faced online abuse herself. Virginia Mantouvalou says that a social media platform shouldn’t be viewed as “safe space” to express whatever views we wish. But isn't one of the points of social media to connect with like-minded people freely? Marie puts that to Will Oremus, a senior writer for tech magazine OneZero.Our posts and comments can incur the wrath of not just online mobs, but of our employers too. And, as journalist and author Jon Ronson explains, the collective online herd mentality leaves no room for forgiveness, or redemption.

How the biggest start-up acquisition out of Nigeria is resonating across Africa. Last year Nigeria saw its biggest ever start-up acquisition - a multi million dollar deal for digital payments company Paystack. The result was a massive shift in the minds of entrepreneurs and investors in Africa’s Fintech scene.

Though children will usually learn how to add, subtract or multiply in school, very often they are not taught the skills they need to manage their money in older life.

Eliminating carbon emissions in the next 30 years would be "the most amazing thing humanity has ever done".In an exclusive interview, Bill Gates tells Justin Rowlatt why he has set his sights on tackling global warming, and how the challenge compares to efforts to contain the coronavirus pandemic - which he is also taking a leading role in, with the funding of vaccine rollouts. The Microsoft founder and world's most influential philanthropist is particularly focused on the parts of the economy that are the toughest to decarbonise - things like cement, steel and aviation.His thinking is strongly influenced by the energy historian Vaclav Smil. Gates says he has read every one of the Czech-Canadian professor's 40-odd books on the subject. But in a rare interview, Professor Smil tells Justin that he has a decidedly more pessimistic view of how quick and painless the energy transition can be.Producer: Laurence Knight(Picture: Justin Rowlatt interviewing Bill Gates at the Natural History Museum)

After years of planning and delays, Africa’s new trade bloc, the African Continental Free Trade Area, opened in January with the promise of transforming the continent’s economies. Amandla Ooko-Ombaka of McKinsey and Company in Nairobi explains the enormous poverty-reducing potential the bloc represents. But some are calling for the agreement’s terms to more directly benefit women, by helping facilitate trade in their wares across borders. Caroline Gethi of the Organisation of Women in International Trade and Gloria Atuheirwe of Trademark East Africa say the agreement hasn't gone far enough to promote gender equality, and that it as yet doesn’t even recognise the role of women in informal trade which is the backbone of Africa’s economies.Producer: Frey Lindsay(Image credit: Getty Images.)
