This weekend, traffic in a key part of Mumbai came to a standstill to make way for a convoy of VIP guests attending one of the year’s most talked about events, the wedding ceremony of Radhika Merchant and Anant Ambani. The couple tied the knot in a 4-day wedding extravaganza with the likes of Kim Kardashian, John Cena and India’s PM Narendra Modi in attendance. It was the glittering finale to 4 months of pre-wedding events which spread across continents and featured private concerts by Rihanna, Katy Perry and Justin Bieber. The spectacle of the whole wedding has divided opinions, with some enjoying the extravagance of it all and others uncomfortable with such a display of wealth in a country facing stark inequality between rich and poor. BBC Delhi reporter, Meryl Sebastian, gives us an overview of the event and wedding culture in India. Plus, BBC Business Correspondent, Nikhil Inamdar, tells us a bit about how the Ambani family made its fortune and the changing wealth landscape in India. And Alex tells all about a disaster at his own wedding!

On Saturday evening someone tried to kill Donald Trump. The former president was giving a speech at a political rally in Pennsylvania when a gunman took aim from a nearby rooftop. The bullet grazed Mr Trump’s right ear before he was rushed to safety.

Images of the defiant presidential candidate, moments after the incident, standing with his fist raised, lines of blood streaked across his face, could impact the election. We look at why. We also discuss security and how the gunman managed to get past US Secret Service agents.

JailTime is a record label that aims to get prisoners away from crime and into the music industry. It operates from a studio in New Bell prison, a high security jail in Douala, Cameroon. They say they’ve brought reoffending rates down significantly.

JailTime’s founders, Dione Roach and Steve Happi, tell us what they're trying to achieve and talk about one of their success stories; Moussinghi. Paul Njie, a BBC reporter in Cameroon, describes the conditions in prisons there - and explains why reoffending rates are so high.

On the other side of the world, the USA has one of the highest recorded reoffending rates in the world. Can arts programmes prevent offenders returning to crime? Maurice Chammah from the Marshall Project gives us his take. He also talks us through the history of music in prisons and describes how prisoners manage to record music from their cells unofficially.

Over the last 18 months the world has gone pretty crazy about AI. Apple has been jumping into the space and Samsung is forecasting higher profits than ever from its advanced chips. Tech companies say it’s the future and may even put a lot of us out of a job. But a new report from one of the world’s top banks says that generative AI, things like ChatGPT or Gemini, might not prove to be the gamechanger that tech companies have been promising.

Generative AI also uses huge amounts of energy and water, behind the super smart tech are massive data centres that drive up greenhouse gas emissions. So we’re asking is AI really going to be worth the cost to our wallets and potentially our planet?

Imran Rahman Jones, a BBC Tech Reporter, tells us how the drive for AI has bumped up Google’s emissions by almost half and explains the ways tech companies are trying to compensate for the surges. Also Ed Zitron, who writes about tech and hosts the Better Offline podcast, tells us why he thinks the hype around generative AI is in danger of becoming overblown.

After the Covid pandemic, global tourism numbers have been on the rise again, but so are concerns about the impact of tourism.

We will take you to Spain, Southern Africa and Hawaii to discuss the tension between the money that tourism brings in, and the price locals have to pay.

Protesters in Barcelona have been showing their discontent with tourists by spraying them with water pistols, trying to scatter visitors from popular areas like La Rambla. Demonstrations against tourism are happening more and more in different parts of Spain. Maria Clara Montoya from the What in the World team explains why the protests have been happening.

And James McCulloch in South Africa and Doctor Kiona in Hawaii talk us through how they set up travel companies with an ethical tourism approach to promote a more sustainable way of travelling.

There’s loads of misinformation online about vaccines. For years, there have been false claims about the tetanus jab causing infertility. One of our listeners, Henry, got in touch to ask us if they were true. Fauziyya Tukur, a BBC Disinformation journalist in Abuja, looks into the claims with us.

The BBC's medical editor, Fergus Walsh explains why vaccine hesitancy is on the rise around the world - and the impact vaccines have had on global health. And we hear from Sahar Baloch, a BBC journalist in Islamabad, who talks about efforts to eradicate polio in Pakistan, amid misinformation about the jab (fuelled in part by a CIA fake vaccine campaign to seek out Osama bin Laden!).

On Sunday night, a surprising exit poll was announced for France’s parliamentary election. It showed that the New Popular Front was about to win the second round, in a result that no-one was expecting.

All previous predictions had suggested the far-right National Rally party would come out on top, but it came third.

The New Popular Front, a brand new left-wing coalition, was formed as part of a strategy to block seats from the National Rally. And even though the plan worked, the National Rally still got its best result in history. But now no party has a majority, meaning France will have a hung parliament.

BBC Journalist, Sara Menai, takes us through what happened and what it means for France.

Dating apps like Tinder, Bumble, Hinge, Match have changed the way many of us date, offering convenience, choice and connection at your finger tips. They have millions of users worldwide. As many as one in three adults in the U.S. has used them, according to Pew Research Centre. But now, ten years after their boom, there’s endless chatter about deleting them. And it’s not because people are finding their Mr or Mrs Right. Some people are opting for advice online and paid coaching programmes instead.

Özge Özdemir from BBC Turkish has looked at the research. She tells us how attitudes are changing about online dating. She’s spoken to psychologists, journalists and young daters about the cultural shift and gives us an overview.

Some app developers have been accused of deliberately making their apps addictive. Elias Aboujaoude a psychiatrist from Stanford University, in the US, explains how some people get hooked.

Also, we get some dating tips from Anwar White, an American dating and relationship coach who specialises in advice for professional women, and women of colour.
