Researching ways to improve your sleep has been popular for years but now it’s evolved and there’s a whole new genre of social media content called ‘Sleepmaxxing’. It shows ways you can build your perfect night’s sleep, by taking magnesium supplements, using black-out curtains or white noise machines. Experts say the popularity has boomed thanks to the accessibility of smart watches which give users sleep scores. We hear from Ollie, who tracks his sleep and is aiming for the perfect score.

BBC reporter Ashitha Nagesh who’s been reporting on the trend, tells us why some experts advise against multi-layered sleep routines and an obsessive fixation with sleep called orthosomnia.

Plus, sleep expert Sophie Bostock tells us how reliable popular sleep trackers are and what they are really measuring.

The issue of safety on college campuses is nothing new. But it’s back in the spotlight again because of the re-opening of a case at Cornell University, New York in the US. A woman alleges she was gang raped at a fraternity party in October 2024. The group is being called the ‘Cornell 7’ on social media. The incident was reported to campus police at the time, but no formal charges were made.

The woman claims she was drugged and raped at a frat house and says the uni didn’t protect her or adequately punish the men she says were involved. Cornell rejects this. Her lawyer says she was traumatised and dropped out of uni.

Now, two years later, state prosecutors have reopened the investigation following a civil lawsuit she’s filed. So - what happened with the case the first time? And what’s different now?

We speak to the BBC’s New York correspondent Nada Tawfik about the case and the conversations about consent, accountability and campus sexual assault.

More and more of us are picking up side hustles - US national employment data shows that the number of people with more than one job is going up year on year, and a survey found that the majority of them are 16-24 year olds. So why are more of us turning to side hustles? And what’s the best way to start one?

We hear from Katie (@katiesgarms), Vera (@viavera_) and Shania (@shaniasvault) who have all started successful side hustles. They share how they got into them and their top tips for getting started. And Chelsea Coates from the What in the World team explains why the current global job market is encouraging more people to pick up second jobs - and the things to look out for if you’re thinking of doing this.

Madonna won Artist of the Year and Taylor Swift made a splash at Sunday’s MTV Video Music Awards - she became the most decorated performer in VMA history, and premiered her music video for Patient Zero, the lead single from the encore to her album The Life of a Showgirl.

And there’s a reason the VMAs might have been so keen to have her - award ceremonies aren’t pulling the big audiences that they used to. Millions of people used to tune in and pore over the outfits and the speeches, hoping their favourite artists would win. But now, viewing figures are falling for shows like the Grammys, the Oscars and the Emmys.

So… why are award shows in their flop era? And what’s being done to revive them?

BBC culture journalist William Lee Adams breaks it all down - and we hear from music fans on whether they think award ceremonies are still relevant.

We’ve seen more and more women talking about cycle-syncing. It’s where you adjust your diet and work outs to match the different phases of your period. Things like eating more in certain phases or taking it easy in others.

But does cycle-syncing help you get better results? Does the science back it up or is it just another wellness trend and rule book for women to follow?

BBC reporter Zara Salaria takes us through what cycle syncing is, we hear from people who have tried it and a doctor breaks it down for us: does it work?

Globally more than a billion tonnes of food is wasted each year and much of it ends up in landfills. As the food breaks down it releases huge amounts of methane, making up 10% of the world’s climate-warming emissions. Now many cities and governments are looking to South Korea as a model of how to reduce food waste and boost food recycling.

BBC reporter Soo Min Kim explains how South Korea cut household food waste going to landfill from 97% to almost nothing. Among other things, they’ve nudged the public to think about their food waste by making it mandatory to separate food waste and to pay for throwing it away. The country also has special RFID bins to handle disposal and payments, and there are financial penalties for people who don’t comply.

We also hear from content creators around the world about how they reduce their food waste. They are: Senjuti Chakraborty in India, Debbi Love in the UK, and Chatty Miss Maddie and Lani Marschall in Australia. Plus BBC reporter William Lee Adams shares some of the surprising food saving hacks he came across on social media.

You may have seen whimsy all over your socials this year. Maybe you’ve been trying to make your days more whimsical? To some, that means taking a moment to appreciate the small things in life: the way the light falls on your desk in the afternoons, or a slow moment spent watching the way the trees blow in the wind. But now, rhinestones have entered the chat and the trend seems to have evolved into something entirely different. There are now concerns that it’s turned into over-consumerism, with people buying gems and other items to be whimsy. When some argue that whimsy simply cannot be bought.

We speak to content creators Karris & Elizabeth about what whimsy means to them. Mollie from the What in the World team talks us through how the trend has grown. And we break down the evolution of whimsy with pop culture writer, Alyssa, and de-influencer, Emma.
