In certain cultures in Uganda and across Africa, a belief exists where departed husbands return as ethereal entities to engage in intimate encounters with their living partners. To ward off this phenomenon, women are required to perform Enkumbi. Ugandan presenter Daniel Leinhardt sets out to investigate this belief and its impact, including the role it may play in subjugating women.

The Children’s Hospital of Entebbe, funded by the Italian NGO, Emergency, and designed by world famous architect Renzo Piano, was established in 2021 to change the situation.

A wave of criminal activity in Japan has been blamed on social media. Yami Baito – meaning “dark part-time jobs” in Japanese – refers to job ads posted by criminal gangs on social media and encrypted messaging platforms including Telegram. Jobseekers are blackmailed or enticed with the promise of getting rich quick to commit a range of crimes from scamming elderly people to, at its most extreme, armed robbery. Japanese police have attempted to crack down on Yami Baito by taking down these ads and launching public awareness campaigns. But BBC Trending explores evidence that these recruiters are still operating online. We hear from someone who got sucked into Yami Baito, and a criminal mastermind in charge of recruitment.

The Los Angeles river has been a concrete channel since the 1930s, when the US Army Corps of Engineers decided to concrete over the original river for flood mitigation. Ever since then, the river has been regularly used as a symbol of dystopia and was the backdrop in a famous scene in The Terminator. However, landscape architect Mia Lehrer wants to transform its reputation and to revitalise the river, because it is still a waterway shared by millions. This will be not be an easy task, however, as the river itself is still the property of the US Army Corps, and the river course crosses numerous bureaucratic boundaries at both the local and state level. Presenter Alan Weedon meets Mia as she describes her vision to breathe new life into an American icon.
