Are health services around the world wilfully blind to the problem of dangerously long hours being worked by junior medics?

Vivienne Nunis speaks to doctors in Australia and America about how tiredness and depression are not only ruining their lives, but also pose a threat to the safety of patients going under the knife or receiving prescriptions. And it's a worldwide problem - as Sydney-based doctor Yumiko Kadota discovered when a blog she wrote attracted similar stories of exhaustion from Colombia to Poland.

Author Margaret Heffernan says the culture of many health systems is one of wilful blindness to the physical limits of human employees, while the campaigning American medic Pamela Wible MD explains how it is driving many hospital staff to suicide.

Our appliances are getting increasingly difficult and expensive to mend, in some cases by design. So should consumers demand the right to repair?

Ed Butler speaks to those campaigning for manufacturers to make it easier for us to fix our electronics goods - with everything from tractors to phones to baby incubators in their sites.

Clare Seek runs a Repair Café in Portsmouth, England, a specially designated venue for anyone who wants to get their stuff to last longer. And Ed travels to Agbogbloshie in Accra in Ghana, one of the places where our mountains of e-waste end up being pulled apart and melted down for scrap.

The programme also features interviews with Gay Gordon-Byrne, executive director of The Repair Association; Kyle Wiens, founder of iFixit; intellectual property lawyer Jani Ihalainen; and Susanne Baker, head of environment and compliance at techUK.

Should the collection of vast genetic databases be dominated by private companies such as 23andMe or Ancestry.com?

In the second of two programmes looking at the businesses riding high on the boom in home DNA testing kits, Manuela Saragosa looks at how the enormous head start these companies have over public sector DNA research initiatives may be skewing medical research.

Will the profit motive drive these companies to wall off their databases, and give access only to pharmaceutical companies capable of developing lucrative new drugs that mainly benefit the predominately wealthy, white customers who send in their DNA samples in the first place?

The programme features interviews with Kathy Hibbs of 23andMe, Mark Caulfield of Genomics England, and Kayte Spector-Bagdady of the University of Michigan Medical School.

The story of Theranos, a company that falsely claimed it could perform a full range of medical tests using just a tiny blood sample drawn by pricking your finger. Manuela Saragosa speaks to John Carreyrou, an investigative reporter with the Wall Street Journal and author of a book on the case, Bad Blood. Plus Silicon Valley venture capitalist Hemant Taneja explains why investors need to be more cautious.

Should Facebook and others be forced by governments to take responsibility for what people are exposed to on their platforms?

Social media companies' algorithms have come under particular scrutiny, with allegations that they push inappropriate content - such as neo-Nazi propaganda, self-harm videos and conspiracy theories - to its users, including to children. "Angry Aussie" YouTuber Andrew Kay describes how the video sharing platform shifted from being a site for video bloggers, to a place where contributors will do or say anything in order to get attention, and thereby earn money.

Meanwhile Professor Alan Woodward, a cyber security expert at the University of Surrey, tells Vishala Sri-Pathma what he thinks governments should be doing to rein these global digital behemoths in.

Poor diet has been linked to diseases such as diabetes and cancer, but do you have much of a choice if you are on a tight budget?

Organic food is rising in popularity in the West, but Vishala Sri-Pathma asks nutritionist Sophie Medlin whether the additional cost of buying organic is actually worth it. And what if you are time poor, as well as short of money? Chef Tom Kerridge has tips for how even if you have just 20 minutes spare, it's still possible to pull together a healthy family meal.

Plus Dr Susan Babey, a senior research scientist for health policy at University College Los Angeles, explains another major factor affecting the diets of many ordinary Americans - so-called "food deserts" where there is simply nowhere to actually buy fresh produce.

How bogus stats can get repeated again and again until they end up influencing policy at governments and major multilateral institutions.

Ed Butler speaks to three people who claim they are struggling to slay these zombies. Ivan Macquisten is an adviser to the UK's Antiquities Dealers Association who actually wrote into Business Daily to complain about a previous programme that he claimed repeated false figures about the scale of looted archaeology from the Middle East finding its way into Western art markets.

Meanwhile, Kathryn Moeller of Stanford University describes how she never found the source of a claim widely quoted by international development agencies that girls are much more likely than boys to invest their income to the benefit of their household. And Rachel Kleinfeld of the Carnegie Endowment for International Peace explains the headache the UN faces in compiling international data about violent crime.

Also in the programme, Lazare Eloundou- Assomo of Unesco and the BBC's own Tim Harford.

Exporters express their fears and frustration at the lack of any agreement about future trade relations with just six weeks left to go until the UK leaves the EU.

Adam Sopher of popcorn manufacturer Joe & Sephs tells Ed Butler how he is now having to send his wares to Asia via air freight, because by the time the usual ships reach dock in Hong Kong the UK will have left already and he still doesn't know what tariffs he will have to pay. Pauline Bastidon of the Freight Transport Association describes how British road hauliers are having to take part in a lottery for permits to continue operating in the EU, with many being left empty handed.

Meanwhile in the Netherlands, MP Pieter Omtzigt, who acts as a Brexit point person for his country's parliament, explains how the Dutch have been preparing far longer than their British counterparts for the possibility of the UK crashing out of the EU with no trade deal at all. Plus Paul Hodges of the consultancy Ready for Brexit explains why so many of the small businesses he speaks to are far from being that.

Are women finally breaking through off screen in the film industry? A year on from the Harvey Weinstein scandal, why aren't there more female movie directors at the Oscars?

Regan Morris reports from a Hollywood still coming to terms with the #MeToo movement. She speaks to Leah Meyerhof, founder of Film Fatales - a movement that brings together female film and TV directors on the West Coast - as well as directors Alyssa Downs and Rijaa Nadeem.

Meanwhile Nithya Raman of the Time’s Up campaign against sexual harassment explains why they have launched the "4% Challenge" - named after the derisory number of top-grossing films directed by women - as well as a legal defence fund and a mentorship programme for women.

Plus actors Armie Hammer and Felicity Jones talk about a forthcoming movie about the pioneering Supreme Court judge Ruth Bader Ginsburg, being directed by Mimi Leder.

Is the era of globalisation, unfettered markets and billionaire philanthropists drawing to a close? Is the answer to rising populism for the state to tax the wealthy and invest more in the public good?

Manuela Saragosa speaks to three people who say the populist revolts, from Brazil to the US, are symptomatic of an economic system in crisis. Winnie Byanyima, head of anti-poverty campaigners Oxfam, explains why she thinks global jobs statistics mask the reality that many people do not receive dignified work or a decent wage.

Development economist Paul Collier of Oxford University says he thinks corporations and billionaires have lost their way in an era of shareholder value and a growing wealth gap, while journalist Anand Giridharadas claims we are witnessing the death throes of the free market ideology that has dominated global politics since the 1980s.

Should your head trump your heart when seeking lifelong love? That's the challenge Business Daily's Justin Rowlatt has taken on for this Valentine's Day.

The hyper-rationalist businessman Ed Conard thinks he knows the answer, and his strictly mathematical strategy for romance is called "sequential selection, no turning back". He used it to meet his wife of the last 20 years, Jill Davis.

But is Ed's approach right for everyone? Justin hears sceptical voices from two very different quarters - romantic novelist Nicola Cornick, and Nobel prize-winning economist Alvin Roth. And what about Jill? What's it like to be on the receiving end of such a calculated courtship?
