Campaigners have told the BBC of several cases of women taking their lives, either after enduring sexual violence or to avoid it. On Tuesday, a major UN report highlighted 'staggering' levels of sexual violence in Sudan, attributing the worst atrocities to the paramilitary RSF group.

Good Bad Billionaire - Patrice Motsepe: Mining magnate

Metal man and football fan Patrice Motsepe rose out of post-apartheid South Africa to become the country’s first black billionaire. Under apartheid, Patrice had to get a special permit to study at an ‘whites-only’ university - the same that Nelson Mandela attended in the 1940s - becoming a lawyer before following the gold into the mines. When the racist regime finally crumbled, he benefited from Black Economic Empowerment initiatives that turbo-charged his wealth. BBC business editor Simon Jack and journalist Zing Tsjeng track Patrice’s rise from asking to do the worst job in the mines to owning them. Then they decide if they think he’s good, bad, or just another billionaire.

CrowdScience - Why do languages fade from us?

Can learning new languages make us forget our mother tongue? CrowdScience listener Nakombe in Cameroon is concerned that his first language, Balue, is slipping from his grasp. He has learned multiple languages through his life, but Balue is the language of his family and home. It’s central to his identity and sense of belonging. So why does it seem to be fading from him, and what can he do to get it back?

We search for answers, investigating what happens in our brains when we struggle to recall languages, as well as the social and economic factors that lead to language loss. Presenter Anand Jagatia asks Michael Anderson from the University of Cambridge, an expert on memory and forgetting, whether forgotten languages disappear from our brain, or just become difficult to access. Linguist Monika Schmid from the University of York takes us through the phenomenon of first language attrition, and has words of reassurance and advice for Nakombe and others in his situation.

And we meet Larry Kimura from the University of Hawai’i at Hilo, a pioneer of Hawaiian language revitalization, and Gabriela Pérez Báez, an expert in indigenous languages and language revitalization at the University of Oregon. They explain why languages around the world become threatened, and how to keep them alive.

Unexpected Elements - Mystery blobs

White blobs have been appearing on the beaches in Newfoundland, Canada. They’re kind of doughy-looking, and smell of vegetable oil. As yet, officials are not sure what they could be. Of course, this got the Unexpected Elements team intrigued, so we decided to dedicate the programme to the weird world of blobs, slime and bizarre things that wash up onshore.

We hear about the fabulous hagfish, which produces copious amounts of snot-like slime to defend itself from predators.

But what makes slime so slippery in the first place? And why is ketchup so hard to get out of a bottle? And what makes quicksand so difficult to escape from? It’s all down to fluid dynamics. Professor Daniel Bonn, from the University of Amsterdam, explains the physics behind all these sticky situations.

Also this week, we find out more about a shipment of bath toys that tumbled overboard, and how they have helped scientists to decipher ocean currents.

Plus, we discover more about the restoration of mangrove forests, how flowers can cause weird dreams, the size of the biggest black forest gateau and a species of plankton and how it floats.
