Divine, a short-form video-sharing app, lets users create and share videos which are just six seconds long and repeat on a loop. It’s inspired by Vine, an app founded in 2012 that, at its peak, had more than 200 million monthly active users. It helped launch the careers of some of the internet's biggest stars, including Jake Paul and Lele Pons.

Laura Cress, a BBC tech reporter, explains how the app plans to shake up social media by banning AI and moving away from an algorithm that feeds people videos specific to their taste and browsing habits. Instead it uses an open, decentralized design that encourages people to engage with similar videos as other users.

Plus: Chelsea and Baldeep from the What in the World team re-enact some of the most iconic moments from the Vine era.

Niu Lai, a low-budget Chinese animation film about a cow in a dream sequence, is going viral. Released on August 5, it earned less than $1,500 in its first ten days. But then — following snarky comments, bad reviews and widespread mockery by Gen-Z — the film found a larger audience and has now brought in more than $1.6 million dollars.

We speak with William Lee Adams, a BBC culture reporter, and Mengchen Zhang from the BBC’s Global China Unit. They discuss the film’s plot, its rudimentary animation and how bad publicity has helped it go viral at home and abroad. We also hear about the origins of the film, which was made by a mother and son over the course of five years.

Plus: Chinese content creator Marcelo Wang offers his hot take, and Utah-based content creator Cameron Cowley shares three of his favourite “so bad they’re good” films.

Across social media young women are discussing the "luteal uglies." These are changes in appearance and mood that women experience during the luteal phase of their menstrual cycle. We hear from women in Vietnam, the Philippines, and the UK about the symptoms they experience, from acne and bloating to fatigue and brain fog.

But what’s behind these changes? Dr Helen O'Neill, an associate professor in reproductive and molecular genetics at University College London, explains how changing hormone levels impact women’s bodies and their brains. She also offers some tips and coping strategies.

AI isn’t just occasionally going rogue…(Open AI and Meta we’re looking at you) it’s also changing the world of work. Nearly 70% of college students in the US said they thought AI would make it harder to find a job in a recent survey - and 22% said that they’ve changed what they’re deciding to study at university because of this. They’re not the only ones… students all over the world are thinking about how to AI-proof their future careers.

In this episode, we go to the University College London campus to speak to three students: Omer, who’s studying French and German, Zahra, who’s studying entrepreneurship, and Allie, who’s just graduated from Kings College after completing her law studies. They tell us how they think AI could change the course of their careers, how they’re adapting to the new technology, and if their degrees will still be helpful in the face of AI.

Rapper Tupac Shakur is one of the most influential music artists ever - with musicians such as Kendrick Lamar, Justin Bieber and Drake citing him as a major inspiration. His career was cut short in 1996 when he was killed in a drive-by shooting in Las Vegas - but now, nearly three decades later, a man is going on trial, accused of his murder. He’s called Duane "Keffe D" Davis - he has pled not guilty and denies all allegations.

So, what we can expect from the trial? And how is Tupac’s music continuing to influence hip-hop, decades after his murder?

We speak to culture journalist Ivie Ani, who’s based in New York, to learn more about the impact Tupac has had on music today. We also hear from Tupac fans that have discovered his legacy in the years since his death - and from Anoushka Mutanda-Dougherty, host of the BBC’s Fame Under Fire podcast. She is in Las Vegas covering the rapper’s murder trial.

What would you do if you found out that your favourite artist was not actually human? More musicians are using AI-tools for their work. But recently, there has also been a boom in AI Personas and 100% AI generated work. Some fans and musicians are not happy, they have called for more transparency around what’s human made. Streaming websites have also raised concerns about fraud and copyright infringement. Tidal and Deezer have outright banned the promotion of this AI content. And now Spotify has announced it will begin labelling songs that are AI generated.

BBC Newsbeat journalist, Eleanor Doyle, talks us through how you can spot AI generated music, how it has made and how regulating it on streaming platforms might work.

Plus, we also hear from two musicians, Marina Josephina in the UK, and Nkasiobi Chukwu in Nigeria about their experiences with AI music.

Orangutans are the world’s most endangered apes and they’re now even closer to extinction. They live on two islands in southeast Asia: Sumatra and Borneo. In November, an extreme weather event in the area killed more than 1,000 people there, plus about 7% of the world’s rarest type of orangutan according to a new study.

BBC Climate and Science reporter Georgina Rannard takes us through how orangutans are being pushed towards extinction and what some countries and charities are doing to protect them.

We also hear from a conservationist making an effort to save the species.
