James Gallagher, the BBC’s Health Correspondent, explains how chatbots work, what the risks are and how the technology is evolving. We also hear from young people about how and when they seek advice from chatbots.

For better for worse, for richer for poorer…but first, can we sign a prenup?
You might have heard about them in relation to celebrity divorce scandals, or even in songs, but recent data suggests prenups aren’t just for the rich and famous anymore. A prenup is a legal arrangement made by a couple before they marry or enter into a civil partnership, which sets out plans for how their wealth will be divided if they divorce. Polls in the US, Canada and the UK show that over half of Gen Z would consider signing one and there’s even a growing number of apps to help you draw up the contract.
So — why are prenups on the rise? And what does it say about modern marriage?
BBC journalist Chelsea Coates breaks down the data behind this - and talks us through the reasons why more of Gen Z are considering signing one. Basma El Atti, a BBC reporter based in Nairobi, explains how marriage differs across the African continent and how conversations around finance before getting married are changing.

For more than three months, Cuba has been struggling under an oil blockade by the United States. It had been getting a lot of its oil from Venezuela, but President Trump put a stop to that.
People in Cuba have been living with all kinds of shortages for decades - food, medicine and of course, oil. This blockade though has made things even more tough and people say they’re exhausted. Santiago Vanegas Maldonado, from the What in the World team, brings us voices of young Cubans who are upset about how their lives have changed and the BBC’s Jose Carlos Cueto Lopez, who is from Havana, takes us through the background to the blockade and what it’s like for people in Cuba.

The Pope is on an 11 day trip around 4 African countries - Algeria, Cameroon, Angola and Equatorial Guinea. This isn’t the only reason why the Pope is in the news though, there’s also been some drama with President Trump, where they clashed over the war in Iran.
A major message from the Pope on this tour (and generally) is “peace”. He’s said “the world is being ravaged by a handful of tyrants.” Some of the countries the Catholic leader is travelling to are dealing with active conflicts.
His visit also shows the increasing importance of Africa to Catholicism - more than a fifth of the world's Catholics live on the continent.
Makuochi Okafor, takes us through it all, from Nigeria. Plus we hear from two young Catholics in Cameroon about their feelings about the Pope’s visit.

Today we’re talking talc… that white powder that is sometimes found in make-up. There’s been a lot of chat recently about the safety of talc. So, in this episode we find out why it’s in our make-up and cosmetics, and whether we should be avoiding it.
BBC journalist Phoebe Keane, who produced the podcast series Talc Tales, explains what talc is and its link to asbestos, a known carcinogen. We also discuss the different tests that are used to determine if talc has been contaminated with asbestos.
The World Health Organization has classified talc as “probably carcinogenic to humans”. Several companies, including Johnson & Johnson, Chanel and L’Oreal have been quietly moving away from using talc-based products in recent years. But do consumers care about this? We hear from Savannah, a PhD student and make-up content creator. And what can you use if you want to avoid talc in make-up? Jen Novakovich, a science communicator and cosmetic scientist, suggests some alternatives.
