Videos of strangers offering parental love are gaining traction in China. POV videos of parents doing everyday things - like telling you to wrap up when it’s cold outside or reminding you not to skip meals - are racking up millions of views. Fans leave lots of comments sending love to their digital mums and dads, but lots of the most popular accounts weren’t originally set up for this purpose. So - why are they so popular?

The BBC’s Eunice Yang, who’s based in Hong Kong, joins us to explain what’s behind the trend - and what it could have to do with China’s former One Child Policy. Assistant professor Ting Guo from the University of Toronto unpacks this too. Plus, we hear from a fan of these internet parent videos, who tell us what the content means to them.

It’s the biggest night in the music industry calendar… every year musicians from all over the world flock to the Grammys in the hopes of picking up an award. But this year, the ceremony is also hitting headlines for the speeches and not just the wins. Bad Bunny and Billie Eilish both called out ICE - Immigration and Customs Enforcement - in their speeches. And off-stage, Justin Bieber and Kehlani attended the ceremony wearing ‘ICE OUT’ badges.

Chelsea Coates and Emily Horler from the What in the World team take you inside their group chat to break down the political statements, the fashion statements (hey there Chappell Roan and Heidi Klum!) and all the highlights from the night.

Plus, Yuna Ku, our reporter in Seoul, tells us about that K-Pop Demon Hunters win. It's gonna be golden baby!

For weeks, President Donald Trump has been threatening to attack Iran and he’s sent what he called an ‘armada’ of combat ships and fighter jets to the region. He’s mentioned two main reasons for the military build-up there: Iran’s nuclear programme and the killing of protesters in the country.

International news organisations are often refused visas to report from inside Iran, so it’s difficult to know exactly how many protesters were killed, but some human rights groups say it could be more than 6,000 people.

In this episode we answer some of your most commonly-searched questions; why is the US threatening to attack Iran, why doesn't President Trump want Iran to have nuclear weapons and what could happen if conflict broke out?

Bhajan clubbing is India’s latest cultural trend. People across the country are swarming to bhajan concerts. Instead of club music and vodka shots, they’re enjoying devotional music, chanting and chai. But it’s still high energy with lots of production, like lasers. Many have praised the events for offering a wholesome alternative to traditional clubbing and a nice way to connect with like-minded people. Lots use the opportunity to get dressed-up in their best traditional glitz too.

And even Prime Minister Narendra Modi has phrased the movement saying: ‘Our Gen-Z is taking to bhajan Clubbing... it is spirituality and modernity merging beautifully, particularly keeping in mind the sanctity of the bhajans’.

So what’s it like at a bhajan club? We’re joined by two friends Pari and Muskan who have attended an event in Delhi. They share why they loved it so much.

For some of us, measles might sound like a childhood disease from the past that our grandparents worried about. But it can have a severe effect on your health if you catch it as an adult and in some regions, infections are rising. Indonesia, Pakistan and South Africa have all dealt with recent outbreaks. And in the countries like US - that were previously recognised as having eliminated the disease - there’s been a rise in cases as well. So - why is the virus on the rise and what does vaccine hesitancy have to do with it?

BBC Health reporter Nick Triggle explains what the virus is, where it’s most prevalent and why we’re seeing a downturn in vaccination rates in some regions. Canada lost its measles elimination status late last year - Nadine Yousif, a BBC reporter in Toronto, explains how anti-vax content on social media may have contributed to this.

Nonstop notifications, exam stress, the fear of being left behind. These are just some of the things which can increase our anxiety levels. We’ve all been there. Stress is something most of us experience. But sometimes that stress can tip over into feeling overwhelmed or even burnout. So - what can you do about it?

BBC presenter and psychologist Claudia Hammond has just written a book all about overwhelm. She breaks down the data on stress, explains what triggers it and gives us her tips on how to deal with it when it all gets too much. And we hear from listeners across the world who share what’s overwhelming them right now - from social media to exams - and get some advice from Claudia on how they can feel less stressed.

Protesters have taken to the streets and tensions are running high in the city of Minneapolis in the US, after ICE agents shot and killed a 37-year-old man named Alex Pretti on Saturday. This comes just weeks after another ICE agent shot and killed US citizen Renee Nicole Good in the same city.

Kristi Noem, the head of the US Department of Homeland Security, accused both Alex and Renee of ‘domestic terrorism’. But some lawmakers - and protesters - have said the killings raise concerns about ICE’s operations across the country.

BBC journalist Kayla Epstein, who’s based in New York, joins us to explain how much power ICE has, why they’re being deployed and why some people say they’re controversial.

Donald Trump can’t stop talking about Greenland. He spent a big chunk of his speech at the World Economic Forum in Davos talking about the island, saying he wouldn’t use force but threatening consequences if it wasn’t handed over.

Later that day, he said discussions with NATO Secretary General Mark Rutte had been fruitful, but Denmark and Greenland said only they can negotiate with the US over Greenland.

We break down why exactly Donald Trump is paying so much attention to this Arctic island and what that might mean for the rest of the world.

Do you know there could be chemicals in your clothes, food packaging and even your make-up which can take hundreds or even thousands of years to break down?

They’re called PFAS - or “forever chemicals” - and they are everywhere. They're in our drinking water, at harmful levels in some areas, and they’re inside our bodies, our brains and our blood. They’ve been found on the top of Mount Everest, too.

BBC climate and science reporter Esme Stallard explains what these chemicals are and how they get into our bodies. Stephanie Metzger from the Royal Society of Chemistry in the UK tells us the effect they can have on our health. And podcast host Robin Laird tells us what she does to try to avoid PFAS.

France has just brought in a ban on cosmetics and clothing that contain these chemicals - they can’t be produced, imported or sold there now. We hear about the steps some countries are taking to try to limit their use. Gittemarie Johansen, a Danish environmental and sustainability advocate, gives us her view on what governments and manufacturers should do.

One of the biggest internet personalities in the world, IShowSpeed has gone viral countless times for his ‘irl’ streams from countries all over the globe. His latest tour of Africa has taken him to a bunch of countries so far, including Zambia, Ethiopia and even the newly-crowned AFCON winners Senegal.

In most countries around the world where there is mandatory military service, it largely applies to just men. Denmark, Sweden and Norway have all brought in conscription laws for women in recent years. Experts say more countries are hoping to strengthen their armies and respond to geopolitical changes or conflict through these new conscription laws. Others say that it reflects a broader discussion and exploration of gender equality across cultures.

BBC reporter Emilia Jansson tells which countries are shifting their focus towards getting women in the army, and explains the reasons why in full.

Where’s the worst place you’ve ever gotten sick? Bet you cant beat space!

For the first time since it launched in 1998, astronauts have been evacuated from the International Space Station because of a health problem. They are now back on Earth, but the rare incident has put the spotlight on just how much preparation goes into space flight - and what happens when things don’t go to plan. So - what can you do if you get sick in space?

BBC science correspondent Georgina Rannard explains how astronauts treat illnesses in space and what it’s like being on the ISS (spoiler: it’s actually VERY hard to keep clean).

Dr Na’im Merchant, an infectious diseases doctor interested in astro-microbiology, explains what kind of illnesses astronauts get in space. And we hear from a former astronaut about staying healthy before and after take-off.
