Albinism is a rare genetic condition that reduces melanin; that’s the pigment that gives colour to your skin, eyes, and hair. The condition can make people more vulnerable to skin cancer and it can also cause problems with vision. There’s a history of discrimination and stigma. Journalist and disability advocate Teejay Ameen talks about his experience of growing up in Nigeria with albinism and how it compares to the UK, where he lives now. Makuochi Okafor, BBC Africa Health reporter, explains what support exists in Nigeria for people with albinism and whether attitudes are changing.

Agronejo is a relatively new genre of Brazilian music. It draws on Brazil’s ever-popular traditional country music, sertanejo but adds a modern twist adding pop, electronic, funk or hiphop.

Crucially agronejo, like sertanejo, celebrates the Brazilian rural and farming lifestyle. The music videos - with farmers in cowboy hats, bling watches, and expensive tractors - are getting millions of views online. Some of the most famous artists are Us Agroboy, Ana Castela, Luan Pereira and DJ Chris no Beat.

But critics say the agricultural industry, or “agrobusiness”, is using the genre to sell an idealised vision of the sector and distract from its environmental impact. The musicians and the industry reject this. Marco Silva, a BBC journalist specialising in climate disinformation, who has made a documentary about this, explains the inspiration behind agronejo. We hear some of his interview with Us Agroboy. And we discuss the environmental impact of Brazil’s agriculture sector and whether this music gives an accurate portrayal of the industry.

In June 2025, a Europe-wide law enforcement operation shut down Archetyp Market, the longest-running illegal drug marketplace on the dark web. 300 officers were involved and assets worth €7.8 million were seized. It’s estimated that Archetyp had over 600,000 users worldwide, with a total transaction volume of at least €250 million, mainly offering illegal drugs for sale, like cocaine, MDMA, amphetamines and synthetic opioids like fentanyl.

BBC Cyber correspondent Joe Tidy explains how the dark web and these marketplaces work as well as what we know about how the police were able to track down Archetyp’s vendors and moderators.

Sinkholes are holes that suddenly appear in the ground. They can be any size but some are enormous. Some have swallowed cars, parts of buildings and even people. There are terrifying videos online of football pitches being sucked into the ground, or the resulting huge circular chasms in the middle of cities. They are found all over the world but some parts of the world are more prone to them than others.

In this episode BBC climate and science reporter Esme Stallard answers our questions about what causes them - and whether you can predict if one is going to happen.

In China, the sink holes there are actually different from the rest of the world. Devra Willingham, from the National Cave and Karst Research Institute in the US, tells us why and what it’s like to go into one.

And we examine if climate change is making sinkholes more common.

Outer space is starting to get crowded. Private companies like Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin are launching rockets regularly, thousands of satellites now orbit Earth, and celebrities like Katy Perry are signing up for space tourism.

There’s talk of more missions to the Moon, and Elon Musk is even hoping for human landings on Mars, within the next decade. But while space tech is racing ahead, the laws that govern it are lagging behind. In fact, there’s only one major international law, the Outer Space Treaty - but that was made ages ago in 1967.

In this episode we hear from three people studying space law; Andre Kwok, a recent graduate at the Australian National University, and Judith Jahnke from Sweden and Martina Elia Vitoloni from Argentina, both at McGill University in Canada. And BBC journalist Freya Scott-Turner explains what laws we already have and why it’s been difficult to agree on more.

What if countries could sue each other for wrecking the climate? Well, that’s now a real possibility after a decision by the UN’s top court, the International Court of Justice (the ICJ). The court made the decision after a group of young law students from low-lying Pacific islands on the frontlines of climate change started a campaign in 2019. But critics say it will be hard to untangle who caused what when it comes to climate change — and that they’re already making good progress when it comes to reducing harm to the environment.

BBC Climate and Science Correspondent Georgina Rannard talks us through what this decision means and how it could impact future climate cases. And we hear from two of the young campaigners who helped bring this case to the ICJ, who tell us what this decision means to them and their communities.

Period tracking apps help you track your menstrual cycle, so you know when to expect your period. They’re growing in popularity worldwide, with the three most popular ones racking up over 250 million downloads between them. But studies show that some women might also be using them to avoid getting pregnant.

One of the apps, Natural Cycles, has been approved in the US to be used as a contraceptive. The company claims it is 93% effective at preventing pregnancies, when used perfectly. So why are more people turning to these apps? Are they safe to use as a contraceptive and what are the risks?

Sexologist Rayka Kumru from Turkey explains why these period tracking apps are becoming so popular and the privacy concerns around using them. Dr Francesco Rampazzo, a lecturer in Demography at the University of Oxford, tells us more about where period tracking apps are getting the most downloads.

Violence has flared up again in Syria, this time in the southern province of Suweida. Fighting has broken out between the government forces and two minority groups: the Druze and the Bedouins. It’s not the first time that the stability of the country has been shaken since the fall of dictator Bashar al-Assad last December. But it signals the challenges the new government faces - not just from internal violence, but from its neighbours. Israel launched air strikes on Suweida and the Syrian capital, Damascus, and says it will only hold a US-backed ceasefire if the Druze are protected. So, what’s behind this conflict - and what does it mean for the future of Syria?

We speak to BBC Monitoring journalist Tess Mallinder Heron, to explain who the different groups involved in the fighting are and what’s behind the dispute. And we hear from our BBC Middle East Correspondent in Damascus, Lina Sinjab, who tells us what life has been like for people in Syria since the fall of Assad’s regime - and how the new government is trying to maintain control in Syria.
