Kerala claims to be the first state in India to have ended extreme poverty. Over the past four years, various government departments have worked together to provide around 64,000 families living in extreme poverty with food, shelter, medical care and scholarships for their children. But what is extreme poverty and why are some people questioning this claim?

The BBC’s Shruti Menon, who is from Kerala, explains all. She also chats us through how extreme poverty rates across India have plummeted in the past decade.

Russia launched a full-scale invasion of Ukraine in 2022. Thousands of schools have been damaged in the war. According to the UN children agency Unicef, only a third of Ukraine's schoolchildren currently study in-person, due to the threat of missile and drone attacks as well as shelling. Russia has attacked energy infrastructure so there are also frequent power cuts across the country. In this episode we hear what life is like for students in Ukraine right now.

Initially Russian forces captured large parts of Ukraine and nearly made it to the capital, Kyiv, but Ukraine pushed the Russian forces back. Now the fighting is mostly in the south and east of the country, but the whole country is affected.

Ukraine has started to build schools underground to allow children to carry on studying during rocket attacks, both purpose-built and by converting existing underground spaces. We speak to BBC reporter Olga Malchevska who has been to see what one of these schools is like.

Another area where education has changed is in Russian-occupied parts of Ukraine. The BBC is not able to travel to these areas but we discuss allegations of “re-education” there.

Sugar taxes are in place in several countries including Mexico and the UK. And they’re evolving. Maybe you’ve noticed that some sweet fizzy drinks are getting more expensive? Buying drinks with added sugar has an extra cost, which is commonly known as sugar tax. It’s a way to discourage people from consuming too much sugar - something which can lead to poor health if consumed in excess. But do these sugar taxes work? Our BBC colleague Maria Clara Montoya has been looking into this with the help of Elisa Pineda, a public health expert from The George Institute for Global Health at Imperial College London.

Colombian archaeologists have retrieved the first items from what’s thought to be the most valuable shipwreck in the world. A Spanish naval ship, the San José, was sunk by a British fleet off the coast of Colombia more than 300 years ago. It had a cargo of gold, silver and emeralds worth billions of dollars in today’s money. Treasure hunters had tried to locate the shipwreck for many years, before Colombia announced that it had discovered it back in 2015.

But how can we be sure this is the actual San Jose - and if it is, who has the rightful claim to the precious cargo onboard?

Helen Farr, a marine archaeologist from the University of Southampton in the UK, takes us through the legal dispute over who owns the ship, and recounts how it ended up on the ocean floor. And we hear from Mariana Carulla, a conservationist in the Colombian ministry of culture, who has been working with the team that’s retrieving objects from the shipwreck. She tells us what they have found so far - and explains how authorities are searching for clues about the shipwreck’s true identity.

Elon Musk could be about to become the world’s first trillionaire. That’s after a record-breaking pay package - that could be worth nearly $1tn (£760bn) - was approved by Tesla shareholders. The electric car boss is already the world's richest man, but this would take his wealth to a whole new level. But who is Elon Musk and how did he make all this money? We explain all, as well as breaking down what a trillion dollars actually is. Plus, we hear from two special guests about what they would do with a trillion dollars.

But not everyone thinks trillionaires are a good thing. Billie Eilish has been vocal about this. She recently called for billionaires to give their money away. And then there’s charities, like Oxfam, who point to rising global inequality. BBC reporter Nathalie Jimenez joins us to crunch the numbers, and explain all sides of the arguments for, and against, trillionaires.

Children learn best when they’re taught in the language they use at home, research suggests. But there's the question about the power of world languages like English, Spanish, French or Arabic and how they could provide more opportunities to those who learn it, be it in education or a career.

You’ve been messaging us about what languages you learned in at school. Say hello to Brian in Kenya and Christian in the Philippines!

We then skip over to Nigeria, where our reporter Makuochi Okafor breaks down for us why the government is reversing its policy of teaching in other languages that aren't English. And our colleague Santiago tells us what went wrong when he was learning in English in his Colombian school.

Plus, we get the research from Justine Sass, from UNESCO - the UN agency for education, science and culture.

GPS interference or GPS ‘jamming’ is getting more common. It’s when radio signals on the same frequencies as GPS satellites are used to overwhelm and block legitimate navigation signals. It’s led to pilots having to make emergency landings or switch to older non-GPS systems. The issue has become so prevalent that the European Union Aviation Safety Agency (EASA) held a conference on it last year. Several European governments also believe it is intentional interference by Russia. BBC journalist Emilia Jansson explains GPS jamming in detail and how it is affecting the aviation industry.

Plus we hear from Ian Petchenik, director of communications at flight-tracking website Flightradar24 about what GPS interference looks like in real-time.

COP30, the big meeting where countries discuss climate change annually, has finished. This year it was hosted in the city of Belem in Brazil, in the Amazon forest, which is directly affected by it. The role of the two biggest emitters has also made headlines. The United States hasn’t taken part in the talks and China has kept a very low profile.

This summit has ended without a clear commitment to phase out fossil fuels and that has angered protesters and activists, who participated in demonstrations showing their opposition to this plan. We wrap up the highlights of COP30 with our resident climate expert, Georgina Rannard and also hear from Natalia Tsuyama, a Brazilian climate activists who shares with us how her first COP has been.

Scientists at Oxford University in the UK now think that kissing evolved more than 21 million years ago, and it wasn’t humans that started it.

As a behaviour, it has no obvious survival or reproductive benefits but it’s seen across the world, in humans and animals alike.

Victoria Gill, our Science Correspondent, tells us all about the research and what we know about if animals can be romantic like humans can.

Miss Mexico Fatima Bosch has been crowned Miss Universe at a ceremony in Bangkok, marking the end of an exceptionally scandal-filled pageant season. It's the 74th Miss Universe pageant and there was a lot of drama before a single contestant took to the stage.

Early in November, Miss Mexico walked out of an event after she was told off by a Thai official and those who supported her were threatened with disqualification.

Then in the days before the final, some judges resigned, one over claims the competition is rigged - which is of course denied by the Miss Universe Organisation.

Social media has shown some of the drama behind the scenes… and at the centre of it is two of the men running the pageant. Nawat Itsaragrisil and Raúl Rocha Cantú have very different visions for the future of the pageant, which has been dealing with declining ratings and financial issues.

William Lee Adams, host of Marketplace Morning Report, takes us through what’s been going on behind the scenes, everything from finances to clashes over how it should be run.

After months of mounting pressure, US lawmakers have just voted to release all of the so-called Epstein files. So documents from criminal investigations into the sex offender Jeffrey Epstein before his death could soon be made public. The vote was passed in the House of Representatives 427-1 and the Senate unanimously fast-tracked it without a formal vote. Now it’s down to US President Donald Trump, who’s already said he’ll release them.

This story has been around for a while, and it’s become a bit of a thorny issue for the US president. Trump used to socialise with Epstein, although there are no allegations of wrongdoing against him. During his re-election campaign, Trump called for the Epstein files to be released. Then, once in power, he changed his mind. But, after a rebellion from some in his own party, he switched sides again, calling for their release.

Following this vote, lots of people have questions: When will the Epstein files be released? What are the Epstein files? And who’s in them? In this episode we explain everything we know so far.

In Sudan, where a civil war has been raging for over two years, millions of students have had their education disrupted. Over half of all schools are in conflict zones. Many schools are being used as shelters and many students have missed their exams. In some parts of the country there is no education at all.

Sudan is one of the biggest countries in Africa. It’s mostly Muslim and is also one of the poorest countries in the world. More than 150,000 people have been killed in the conflict, and around 12 million have had to flee their homes. The UN has called it the world’s biggest humanitarian crisis.

In this episode school and university students in Sudan tells us how their education has been affected by the war. And BBC journalist Maha El Gaml explains how some schools are now re-opening.
