Just an hour and a half after the clock struck midnight on New Year’s Day 2026, a fire broke out in a bar in Crans-Montana, a ski resort in Switzerland. At least 40 people are confirmed to have died in the blaze and over 100 are injured. Most of the party goers were young people celebrating the start of the New Year. Patients as young as 15 are being treated for severe burns.

The exact cause of the fire has not yet been confirmed, but authorities have said that the fire was likely an accident and an investigation is already underway. In this episode, we explain what we know about what happened and we hear from people who were in the bar that night as well as BBC reporters covering the story.

Women’s appearances have often come under heavy scrutiny, especially their weight. The ideal body type has changed again and again. But in the wake of the body positivity movement of the 2010s, it seems like super skinny models are more prominent once more.

There’s a lack of diversity being shown in the fashion industry and across social media. According to the Vogue business report for Spring/Summer 2026, there were fewer mid-size and plus-size models on the catwalks in 2025. So what’s behind it, and what could the effects be? Imogen James from the What in the World team gets into the trend.

We also hear from Norwegian model Karoline Bjornelykke, who has experienced working while very thin and being forced into diets, as well as being a curve model.

Nostalgia. That reminiscent, comforting feeling of something from the past that is familiar. We get it with different things, from fashion to TV shows and music. In the last few years, there’s been a huge rise in things like y2k fashion, old school technology like flip phones and digital cameras, and even Kate Bush has made it back into the charts.

So why do Gen Z care so much about old things? Professor Ryan Lizardi tells us more about how nostalgia works, when it’s bad for you, and how marketing is keeping old things alive. We also hear how nostalgia is interpreted from Marie Tusiama in the Ivory Coast, who runs a successful y2k Instagram page.

And what does nostalgia mean in Portuguese and Brazilian culture? Well, we hear from someone else in the Gelbart family - Ben tells us about his favourite Portuguese word, ‘saudade’.

Are you an extrovert or an introvert? Do you enjoy small talk with strangers or do you do everything you can to avoid catching their eye? Type A or Type B?

Right now the internet is obsessed with these labels. Personality types, birth charts, attachment styles, Myers Briggs, colour coding your aura.

These days the internet is full of tests that attempt to define who you are by answering questionnaires, but the reality is more complicated. We go through these trends with Claudia Hammond, a psychologist and BBC presenter. Plus we hear from BBC colleagues in other parts of the world. Yuna Ku tells us the trends around personality types in South Korea and Makuochi Okafor in Nigeria explains how Igbo culture defines people’s characteristics according to four categories.

From the Caribbean to the Mediterranean, tonnes of seaweed is turning up on beaches in ever bigger quantities. Seaweed blooms — massive, rapid accumulations of seaweed — are smelly and can release toxic gases. They’re also crowding out native plants. So where is all this seaweed coming from and is it down to climate change? BBC climate and science correspondent Georgina Rannard explains what effect this extra seaweed is having on biodiversity.

Lots of countries and scientists are trying to work out what to do with all this seaweed - and even find ways to use it in the fight against climate change. We speak to Santiago Stebelski, who’s 20 and from Mexico. He and his brother have just founded a company called Sargolico, which aims to convert sargassum seaweed into bioplastic.

Football fans all around the world are gearing up for the 2026 Men’s World Cup. It’s set to be a historic tournament and will be hosted by three countries for the first time: the United States, Canada and Mexico. But some fans says it will make the history books for the wrong reasons - because of the jump in ticket prices.

Group-stage tickets are up to three times more than those for the 2022 World Cup in Qatar and the cheapest ticket for the final will cost hundreds of dollars. FIFA has announced that it will release a small number of more affordable tickets, but some fans say this is not enough.

BBC Africa Sports Reporter Celestine Karoney explains the costs of attending the 2026 World Cup - and how the tournament could also be affected by US‘ immigration policy. We also hear from fans in Cape Verde, which has qualified for the tournament for the first time, and in the Ivory Coast about the barriers they have faced when trying to get tickets to World Cup matches.

Are your work emails too polite? Do you use unnecessary punctuation and emojis? Career experts have told the BBC that using multiple exclamation marks can seem fake or could impact credibility.

At the end of November, Ethiopia’s biggest social media creators gathered in Addis Ababa for the Ethiopia Creative Awards. It was supposed to be a night celebrating the thriving digital culture but the outfits of the attendees stole the spotlight. A few weeks later six creators were arrested and detained for wearing “indecent attire” at the event and undermining public morality - but what exactly does that mean?

Kalkidan Yibeltal, a BBC journalist based in Nairobi, tells us about cultural expectations for clothing in Ethiopia and why the outfits sparked so much controversy there.

Iran is facing its worst drought in decades, with rainfall hitting a record low. Several of the reservoirs that supply water to the capital Tehran are almost empty: one of them, the Latian Dam, is currently holding less than 10% of its capacity. The government is encouraging people in Tehran to use less water and putting heavy restrictions on water supplies, especially at night.

But Iran’s president, Masoud Pezeshkian, has also suggested another solution - relocating the capital.

BBC journalist Ghoncheh Habibiazad outlines these plans and explains what other solutions Iran is using to tackle the problem. We hear from someone living in Tehran about what it’s like living with extreme water shortages. And the BBC’s climate and science correspondent Georgina Rannard explains how climate change is contributing to this drought - and what solutions Iran could use to mitigate water shortages.

Charity used to be about bake sales and running marathons. Now it’s all about thumbnails, hashtags, and stunts.

Recently, MrBeast ran a massive campaign called #TeamWater - he partnered up with WaterAid and 10,000 other content creators. It raised over $40 million and is the biggest example so far in terms of number of influencers involved in a charitable campaign.

Now other influencers, and charities are following this trend - working together on campaigns. So what happens when charity becomes content? Does this represent the future of philanthropy?

Makuochi Okafor, a BBC reporter in Nigeria talks us through this growing trend and we hear from Gisela Amponsa, a Ghanaian digital creator, who was part of the #TeamWater campaign.

Taiwan is an island about 180 kilometres off the coast of China - nearly 24 million people live there. Taiwan is self governed but China says it’s part of its territory. Only 12 countries (plus the Vatican) officially recognise Taiwan as a country. Taiwan is increasingly worried that China could be preparing to take the island by force.

Whatever happens there could affect your whole online life, because Taiwan makes most of the world’s computer chips, which power your phone, your laptop, AI apps and electric cars.

In this episode Shawn Yuan from the BBC’s Global China Unit explains the relationship between Taiwan and China and how the whole world could be affected if conflict broke out.

We also hear from Taiwanese students Yi-Ting and Louis and Chinese student Rongzhi, who tell us how they feel about Taiwan-China relations.

Vases crafted thousands of years ago, temples built by past civilisations, natural parks with stunning waterfalls. These are all tangible things, there is a physical trace of them and many times they are protected and valued.

But what about festivals, recipes or dances and skills that are unique to a certain part of the world? These cannot be stored, really. However they are passed on, become part of many people’s identities and are known as intangible cultural heritage.

UNESCO, the United Nations agency that focuses on culture and education has released its yearly list recognising these practices. But what does it actually mean to be included and why is it celebrated? We hear from Matthieu Guevel, Chief of Communications at UNESCO.

Plus we talk to three people whose cultural practices have been added to the list this year: Paola Maggiulli a British-Italian cook, Lika Kat, a content creator from Kyrgyzstan and Zahra Hankir, a Lebanese author and journalist.

Stray Kids or BlackPink? Spice Girls or Westlife? Music executives - like Simon Cowell - have been creating girl bands and boy bands for decades. And he’s about to launch a brand new competition on Netflix to find “The Next Act”. When we talk about these groups, we generally mean good-looking young women or men who’ve been brought together, and who don’t tend to write their own songs or play their own instruments. Their fans are stereotyped as being teenage girls and their mums.

Is there any truth to the belief that girl bands make better music because they are held to higher standards? The BBC’s music correspondent Mark Savage explains how pop bands have evolved over the decades. We look at the different pressures and stereotyping that girl and boy bands face and we hear from some of our BBC friends - do they prefer girl bands or boy bands and why?

More than half a million people have been forced to leave their homes in Cambodia and Thailand. This follows rising conflict over the two countries’ shared border. Now, this is not a new dispute. In fact it’s been going on for decades. But this year things have gotten worse. A ceasefire was negotiated by US president Donald Trump in October. But it hasn’t held. Trump now says he will ‘make a phone call’ to stop the fighting.

BBC reporter Panisa Aemocha, in Bangkok, chats us through the humanitarian needs of hundreds of thousands of evacuees. We also from the BBC’s South East Asia correspondent Jonathan Head who’s at an evacuation centre, and from two young people who have fled their houses.

The Trump administration says it has killed dozens of people in strikes on boats in the Caribbean and Pacific, which it says are from Venezuela and are carrying illegal drugs bound for the US. The US hasn’t provided any evidence or details about those who have been killed. Experts have questioned the legality of these strikes.

President Trump has alleged the Venezuelan leader, Nicolas Maduro runs a criminal group called Cartel de los Soles. Maduro denies this and has accused the US of using its "war on drugs" as an excuse to try and remove him from power to access Venezuela’s huge oil reserves.

Mimi Swaby, a BBC Global Affairs Reporter who focuses on Latin America, explains the history between the US and Venezuela and why the US is launching strikes on boats.

Australia is banning social media for everyone under 16. The government says it’s to protect children from cyber bullying, harmful content and online predators. TikTok, Snapchat, Instagram, YouTube, X (formerly Twitter) - they’re some of the platforms that are going to be banned. Meta, which owns Facebook, Instagram and WhatsApp, has already started kicking under-16s off its apps. An estimated 150,000 Facebook users and 350,000 Instagram accounts are expected to be affected. The social media ban will come in to effect from December 10.

Lots of teenagers are unhappy about this social media ban. But what about Australians who are now over 16? Do they wish they’d had something similar? We chat to Felix, 20, Lia, 19, and Habibat, 21, to find out.
