Most people in the world speak more than one language and many countries have more than one official national language. But what is it like living as a polyglot? And what advantages can it bring to your health? Studies have shown that speakers of multiple languages get dementia later and even recover better after a stroke.

BBC journalist Victoria Uwonkunda describes what it was like growing up as a polyglot and how she deals with speaking multiple languages in her daily life. Turkish polyglot Iclal Dagli, who speaks nine languages, tells us how she uses music to learn languages she finds difficult.

Plus, Professor Frédérique Liégeois, a cognitive neuroscientist at University College London, explains the benefits speaking multiple languages has on your brain, and how it could help to maintain your brain health as you get older.

One of the most eye-catching decisions by Donald Trump since becoming American President for a second time was to freeze foreign aid. USAID is the agency that’s given billions of dollars to global projects, from disaster relief to fighting malaria.

With this decision there will be a big hole in global financing, one that could potentially be filled by other leading global countries, such as China.

President Xi has already upped China’s foreign spending in places like Africa. Chinese investing in huge infrastructure projects abroad isn’t new, but could they use America’s decision to their advantage and extend their influence around the world?

Shawn Yuan, from the BBC’s Global China Unit, explains how Chinese aid models differ from the US. We also hear from Janice Nkajja, a Ugandan TikToker and social justice activist whose video went viral when USAID was frozen. And Daniel Dadzie, our reporter in Ghana, takes us through China’s funding strategy in Africa.

Half of the Kenyan population use TikTok everyday. But when the sun sets, darker content appears on the platform. Girls as young as fifteen are advertising their bodies through livestreams and avoiding being caught by using coded messages. It’s a way for them to make money - but TikTok is also profiting, despite their strict rules on underage and sexual content.

BBC Africa Eye reporter Debula Kemoli has been to Kenya to investigate. She tells us what she uncovered, and shares insights from content moderators and the women and teens participating in the livestreams.

At the end of last year, astronomers detected 2024 YR4, an asteroid that could collide with Earth on the 22nd December 2032. It was dubbed the ‘city-killer’ and news reports warned of Armageddon, comparing the potential impact to a nuclear bomb explosion. But since YR4’s discovery, space agencies and scientists have been studying the asteroid’s size, potential path and what we can do to divert it. There’s only the tiniest risk it will hit earth and experts say there’s no need for alarm.

BBC science and climate reporter Georgina Rannard talks us through all the details of Asteroid 2024 YR4, and gives a quick history of how we’ve managed asteroids in the past.

The illegal drug trade is booming in Europe due to a growing and profitable demand for cocaine. It can be sold for almost double the price you can get for it in the US. Belgium and the Netherlands have been named as the new cocaine capitals, as the major container ports there have been infiltrated by drug smuggling gangs, and the US market becomes saturated and turns to opiates instead.

But how does cocaine get to Europe? And who’s operating these gangs? We speak to two journalists who’ve been looking at the illegal drug trade in Europe; Anna Holligan, BBC correspondent in the Netherlands, and Gabriel Stargardter, a Reuters journalist in Paris.

As more drugs are routed to Europe, countries in West and Central Africa are increasingly being used as key transit zones. Lucia Bird from the Global Initiative Against Transnational Organized Crime tells us what impact it’s having on those countries.

Plus David Hillier, a freelance British journalist, explains what kinds of illegal drugs Europeans are currently taking.

Naomi Watanabe is a Japanese comedian, fashion icon and social media powerhouse. She shot to fame in 2008 with her viral Beyoncé impression, earning her the nickname ‘Japanese Beyoncé. Now, with 10 million followers, she’s one of Japan’s biggest influencers. But that wasn’t enough for her. Four years ago she moved to New York to do stand-up comedy on the global stage.

Hannah went to New York in October to see her debut stand-up show, speak to fans and meet Naomi in person. Naomi talks about adapting to life in NYC, the rats, and what it’s like on dating apps when you’re super famous.

She’s also a body positivity icon. In Japan, one in five young women is underweight and there’s immense pressure to be thin. Naomi shares her feelings on body image and explains why she set up her own fashion label, Punyus, which means ‘chubby’.

And Mariko Oi, a BBC reporter from Japan, tells us about her experiences with Japanese perceptions of the ideal body shape.

Watch out for the full interview between Hannah and Naomi on the BBC World Service YouTube channel.

America’s Next Top Model — the reality competition series hosted by Tyra Banks — continues to face criticism years after it stopped airing. And it’s not the only reality show that critics say hasn’t aged well. From Cops to The Swan to Mr Beast’s new show Beast Games, reality TV routinely courts controversy.

We all know reality shows like The Traitors, Keeping Up with the Kardashians, The Real Housewives and Love Island. But how did the genre become so popular in the first place? We hear from Danielle Lindemann, a sociologist at Lehigh University and the author of ‘True Story: What Reality TV Says About Us’. She explains how shows like The Real World and Survivor helped define the genre and unpacks some of the biggest scandals from reality TV history.

We also chat to Angelea Preston, a journalist in New York and a former ANTM contestant. She won Cycle 17 — the show’s All-Stars edition — but had her title revoked after producers learned that she had worked briefly as an escort. She gives her take on some of the show’s most infamous photo shoots.

And what about makeover shows? Well Tawnya Perrotta — who appeared on TV as Tawnya Cooke — underwent several procedures for The Swan, a show where contestants spent months undergoing plastic surgery and therapy before competing in a beauty pageant.

And we hear from Big Brother Naija contestant Mr KayVee, who famously walked out of the house after having what he calls a “mental breakdown.”

Ne Zha 2 has just become the highest-grossing animated film of all time globally. It’s a fantasy film about a boy’s quest, fighting demons with magical powers, based on Chinese mythology. It’s now in the top 10 biggest movies in history and it could end up beating Avatar, as people are still going to see it. This is the first time the Chinese film industry - which is in large part controlled by the information arm of the Chinese Communist Party - has created such a successful film.

BBC journalist Koh Ewe explains why this film has been such a hit, and what this tells us about Chinese cinema. Kerry Allen, who monitors Chinese media for the BBC, explains what the reaction’s been like in China and film reviewer Sully from @SullyStreams on YouTube gives us his verdict on the film.

Three years after Russia’s full-scale invasion of Ukraine, tens of thousands of people have died and hundreds of thousands more have been injured. Now U.S. President Donald Trump thinks he can broker peace by negotiating directly with Russia’s president Vladimir Putin.

Vitaliy Shevchenko, BBC Monitoring’s Russia editor, explains how the war started and how severe it has become, assesses some of the misinformation that President Trump has repeated over the past week, and unpacks what we know about the proposed peace plan.

A generation of young people have had to come of age during the war. We hear from three of them — Maryna, Olga and Volodymyr. They explain how their lives have changed, how they feel about President Trump’s recent comments, and how they keep hope alive.

People should have access to around 50 to 100 litres of clean water per day, according to the UN. But this is not always the case, especially in countries with desert areas or affected by droughts.

There’s a technique called fog catching that’s been used on a small scale for decades. Nets are used to trap fog and water is channelled into pipes and storage tanks. But now, in the Atacama Desert in Chile, researchers want to scale it up massively and meet the entire water demand of Alto Hospicio, which is in one of the world's driest regions.

How much water can fog catching provide? And is it clean? The BBC’s Science Correspondent Victoria Gill runs us through how it all works. And we hear from two organisations working on improving access to water across Africa and Latin America.
