In recent years component parts of historic shipwrecks have started to disappear, with reports of mysterious vessels and scavengers floating around. This phenomenon has been reported in Indonesia, Australia, and the Netherlands. One theory is that the target for plunderers is pre-atomic steel, i.e any steel produced before the nuclear testing era, and therefore free of radioactive particles. Its purer material composition makes it essential in the manufacturing of specialist scientific tools such as MRI machines, and as such is highly valuable. Shipwrecks - oftentimes war graves - are one of the few remaining sources for this material. Materials scientist Anna Ploszajski investigates a murky picture of illegal plundering across the globe.

More than 300 children were kidnapped from a school in the Western Nigerian village of Papiri in November, but in the aftermath, accounts of the kidnappings were confused and misleading. BBC Africa's Madina Maishanu was part of a team of journalists who faced huge risk to visit the site of the kidnappings and hear the testimonies of parents. In October this year, a young Chechen woman living in Armenia, Aishat Baimuradova, was killed. She'd previously escaped a repressive life in Chechnya but is now believed to be the first Chechen woman in exile to be killed outside of Russia. BBC Russian's Zlata Onufrieva and Olga Prosvirova set out what is known about Aishat's life and death, and consider the implications of her killing for Chechen women living in exile. This episode of The Documentary comes to you from The Fifth Floor, the show at the heart of global storytelling, with BBC journalists from all around the world. Presented by Faranak Amidi. Produced by Laura Thomas, Caroline Ferguson and Hannah Dean. (Photo: Faranak Amidi. Credit: Tricia Yourkevich.)

From 10 December, Australian children under 16 will be banned from most social media platforms including TikTok, YouTube, Instagram and Snapchat. The ban is designed to protect teenagers from harmful content and other risks such as cyberbullying and grooming. Surveys suggest the legislation is popular with many parents, but it has been challenged by social media companies and some young campaigners have argued it disregards children’s rights. We bring together two families in New South Wales who are on opposite sides of the debate. We also hear from three young Australians with tens of thousands of social media followers, including Ella who says, "it’s the content that needs to be removed, not us".
