El Niño has been strengthening for several months now and is already having a significant impact on global weather patterns.

Countries including Indonesia, India and the United States have been experiencing droughts, floods and heatwaves in line with projections about how extreme weather events will be supercharged by the phenomenon.

Have a look at the label in the clothes you’re wearing today. Chances are, you’re wearing some polyester. It’s the most- produced synthetic fibre on the planet and it’s having a bit of a moment on socials. In a bad way…people are giving it up and swapping for more natural fibres.

You might’ve seen claims that polyester is linked to diseases like cancer and can cause fertility issues. But how worried should we be? Professor Mohamed Abdallah from the University of Birmingham breaks it down for us and Chelsea Coates from the What in the World team explains how we can make better clothing choices.

Is educational content about women’s reproductive and sexual health being removed or restricted on social media apps? Content moderation tools are meant to flag specific words and imagery that breach platform guidelines, like showing nudity or explicit content, but posts that use clinical terms like ‘vagina’ are getting blocked too.

What began as a peaceful protest in Albania turned violent in October, as students took the lead, setting buildings on fire and clashing with police. They are demanding better university conditions, greater opportunities for young people – and an end to what they describe as a corrupt government.

This all goes back to a proposal to build a huge, luxury tourist resort in Zvërnec, where there’s a flamingo reserve. US President Donald Trump’s son-in-law, Jared Kushner, is among the investors. But locals were unhappy at the impact the proposals would have on the flamingos and the nature in the area. So, they began to protest.

The Flamingo Movement has grown, and crowds are now chanting not just about the environment, but schools, jobs and living standards. We hear from some protesters, including 23-year-old activist, Brunela, who has become known as “the girl who started the revolution”. And Rita Behadini from the What in the World, breaks down the political landscape of Albania.

Shoes on or off? Laptops in or out? And don’t get us started on the rules around liquids! Getting through airport security never seems to be simple. It’s there for a reason, of course. But there are so many rules and why do they seem to be different everywhere you go?

We’re joined by science journalist and presenter Caroline Steel to talk about everything from the miles long luggage belts our suitcases travel on, how x-ray scanners work, what they’re looking for and whether or not they can ACTUALLY see us naked.

Singapore’s got a reputation for being one of world’s cleanest cities. But right now, it’s covered in a thick blanket of smog. And it’s recently seen its worst air quality levels for the year. The reason? Fires in nearby Indonesia.

Indonesia’s seen its worst wildfire season in years. Huge areas of land have been burning for weeks. Fires are sometimes lit as a way to illegally clear land to make room for plantations - a process known as ‘slash and burn’. Hot and dry conditions caused by extreme weather mean the fires grow and spread easily.

We hear from people in Singapore and Indonesia about how the fires and resulting haze are affecting their daily lives. Plus, BBC reporters Tessa Wong in Singapore and Liza Tambunan in Indonesia explain how both countries are responding.

It’s no surprise more people want to become influencers - a study found that in 2024, YouTube content creators alone contributed £2.2bn to the UK’s economy. But… would you pay thousands to study how to be one?

A growing number of universities around the world, like Arizona State University in the US, have started offering Content Creation courses. We hear from Martyna who is currently studying BA Content Creation at Nottingham Trent University in the UK.

So are these courses the best way to become an influencer? Or are they more about training to go into a career in online marketing?

BBC journalist Megan Lawton takes us through the stats and Daanish (@doctordaanish), a medical doctor and influencer, gives us his take on these degrees.

There’s just SOMETHING not quite right about that French influencer we’re seeing all over socials. His blonde bob, the suit he wears, and that moustache! His name is Jean Philanthrope, and his videos have wracked up millions of views. But, it turns out, he’s not real. He’s AI and he’s being used to promote a risky type of crypto called a Meme coin.

We speak to BBC Verify’s Marco Silva about how he investigates characters like this, how they work, and what you can do to keep yourself safe from falling for this kind of content. Artist and performer Nadir Josi also tells us his concerns about the ‘copy and paste culture’ of the internet, and what it means for the future of art.
