For three years a brutal civil war has been raging in Sudan. Hundreds of thousands have been killed. Millions have been forced from their homes. But the war has other hidden costs – particularly for the young. It’s estimated that 60% of the population is under 25, and millions have lost out on their education. Now after the capital Khartoum was recaptured by the army, for the first time in years, school and universities have re-opened in the city. But as Mohanad Hashim reports, the lives of Khartoum’s youth are still shaped by war.

Renowned Danish chef Trine Hahnemann tells Sahar Zand how she combines the concept of hygge with her cooking. Hygge is a word that is embedded in the Danish language. It’s about relaxing and taking time away from the daily rush to enjoy life's quieter pleasures. And yet, Trine finds the time to write cookery books (over 20 so far), and run cookery lessons from the kitchen in her family home in Copenhagen. She tells Sahar how she does it, as she prepares a comforting meal of freshly harvested vegetables, and explains how she started her culinary career by cooking for rock stars on tour, including Red Hot Chilli Peppers, The Rolling Stones and Elton John.

Potatoes are having a moment. Once dismissed as dull, stodgy or even unhealthy, they are now back, appearing on restaurant menus, in food magazines and across social media feeds. But the story of the potato goes back much further. Ruth Alexander traces the journey of one of the world’s most familiar foods. From its origins millions of years ago to its place in today’s global food system. AJ Shehata, senior sous chef at Fallow restaurant in London explains why the potato forces chefs to get creative. At the Natural History Museum, botanist Sandy Knapp explains how the potato may have been born from a chance encounter between two wild plants in the Andes, an event that made it possible for potatoes to grow underground and spread across new environments. Potatoes USA president Blair Richardson explains how demand continues to grow worldwide, and how the industry is working to reshape the potato’s image. Nutrition scientist Candida Rebello shares research suggesting potatoes may be far more beneficial, and more misunderstood, than many people think. And, at the International Potato Centre in Peru, scientist Julian Soto works with farmers to conserve thousands of native potato varieties. In the Andes, potatoes are not just a crop, they are part of culture, identity and family life.

For more than 80 years, no-one knew what happened to a Soviet prisoner of war who escaped from the Nazis on the Channel Island of Jersey and spent the rest of World War Two hiding from the German occupiers with a local family, the Le Bretons. Known only by his first name, Bokejon, or simply Tom, he was one of about 2,000 Soviet prisoners and forced labourers brought to the island of Jersey to build Nazi fortifications. After liberation, Tom and the other surviving PoWs were sent back to the USSR and the Le Breton family, particularly their daughter Dulcie, always wondered what became of him. That was until BBC teams tracked down his descendants. BBC Russian's Olga Ivshina was one of the journalists who tracked him down.

Political violence has been a problem in Kenya for decades now. It is often carried out by gangs of young people, known as 'goons', who are sponsored by politicians to threaten, disrupt and attack rivals. After the general election in 2007 over 1500 people were killed and with another election planned for 2027, there are fears violence could erupt again. Wycliffe Muia of BBC Africa has been looking into these politically sponsored violent gangs and what can be done to stop them.

 Traditional fortune telling culture,  known as Saju, is popular in South Korea and has ancient roots. It uses data such as a person's birth year, month, day and hour to determine their future and in South Korea people still sometimes consult it before important life decisions like marriage, or seeking a new job. Now, the practice of Saju is beginning to be combined with AI technology and it's finding a wide audience both online and as a walk-in, more immersive experience. BBC Korean's Yujin Choi went to try it out.
