BMX Freestyle is one of the events at the 2024 Urban Cycling World Championships which are being held in Abu Dhabi. It features fearless BMX riders jumping, spinning and hurling themselves around the course on a small bike, pulling off mind-blowing tricks that get you gasping. Think acrobatic gymnastics but on a bike.

What does it take to become a BMX rider though? Tom Clemens from Germany, who sits 18th in the BMX Freestyle world rankings, tells us how he became a professional BMX rider.

Plus, Olympic commentator and professional skateboarder Lucy Adams explains how BMX Freestyle riders compete, and how new ‘action’ sports like BMX are trying to grow their popularity.

A law passed earlier this year means TikTok will be banned in the US unless it is sold by its Chinese parent company, ByteDance, before 19 January 2025. On Monday US President-elect Donald Trump met the company’s CEO, Shou Zi Chew, and now people are questioning if he will try and stop this ban, and save the app.

Rhiannon Williams, a UK-based tech journalist, talks us through how Trump’s relationship to TikTok has changed over the years, including how he utilised it to target young people in the presidential election, and why some people are calling this a clever move politically.

Plus Natalie Jimenez, a BBC reporter based in New York, reviews Trump’s TikTok page for us and shares if it’s hot, or a flop.

Game of Thrones. Twilight. Little Red Riding Hood. The wolf is an animal that appears more than most creatures across popular culture. They’re known for being fierce, dangerous and scary. Is this what they are like in real life though? Abby Keller, who works at the International Wolf Centre in the US, tells us everything we need to know about wolves.

For 45 years in Europe, grey wolves were under the second highest level of protection in European Union laws. This is called Annex Two and offered ‘strict protection’. This month though, EU conservation officials voted to downgrade them to Annex Three. It means they have gone from ‘strictly protected’ to just ‘protected’. From March next year, each EU nation will be able to set a yearly figure of how many wolves can legally be killed in their country.

The BBC’s Emilia Jansson explains the decision and what it means for the wolf population of the EU.

There’s nothing quite like going to see a new film in the cinema; the big screen, surround sound, buckets of popcorn and collective gasps from the audience. But the film industry has experienced a number of setbacks in recent years, including the pandemic, competition from streaming, and Hollywood strikes.

Annabel Rackham, a BBC culture reporter, talks us though whether cinema in the United States, and elsewhere, is bouncing back, and how mega hits like Wicked and Gladiator 2 are helping.

We also speak to Mr C, a film critic from Nigeria who now lives in the UK, about how cinema is faring in Nigeria. And Adam Chowdhury from the What in the World team quizzes Hannah on some (pretty surprising) film-related Guinness World Records.
