Imagine losing your home, your job or your reputation, all because of a computer error. We speak to people who say that's exactly what happened to them.
Kim Duncan and her children lost their family home in the US after Kim's bank Wells Fargo mistakenly said she didn't qualify for a loan modification she needed to keep up with her repayments. Meanwhile in the UK, the Post Office is being litigated by former employees who were fired and in some cases went to prison after being accused of fraud - they claim because of a bug in the Post Office's accounting software.
Manuela Saragosa asks computer science expert Lindsay Marshall of Newcastle University whether glitches like these are unavoidable. Do they have to be so damaging, and are they likely to become an ever more common bane of our lives?

The global affordable housing crisis
Do rent controls and the expropriation of apartment blocks provide an answer to the increasing cost of housing in the rich world?
Such radical measures are being considered in many of the world's biggest metropolises, as more and more residents find themselves being priced out of their home cities.
Manuela Saragosa speaks to Tom McGath of the Berlin-based campaign group Deutsche Wohnen Enteignen, who wants the city authorities to seize ownership of housing from the German capital's biggest landlords. But leading urbanist Richard Florida of the University of Toronto says there are better ways of tackling the shortage, not least taking on the "not in my back yard" brigade.

Pricing in climate change
Are markets and companies beginning to grasp the threat of global warming? Ed Butler speaks to Meryam Omi, head of sustainability and responsible investment strategy at Legal and General, a major investor, about divesting from companies that contribute to climate change. And Jeff Colgan, director of security studies at the Watson Institute, Brown University, in the US, tells us why he thinks sectors like insurance, property and oil and gas are overpriced given the threat of climate change. Bjorn Otto Sverdrup, senior vice president for sustainability at Equinor, Norway's state-back oil company, outlines what changes his company is making.

The true cost of periods
Periods. We rarely talk about them but half the world's population will have to manage menstruation for a good chunk of their lives.
For some women, their monthly period brings shame and stigmatisation, as they are forced out of their communities. Others simply can't afford the products they need to carry on with their lives.
Ruth Evans reports from Nepal on some of the challenges and the solutions being developed, to help improve the lives of millions.
We also hear from Janie Hampton, of World Menstrual Network, who's calling for drastic change in the way periods are managed, not just in poor communities but in the developed world, too.
