A rare and ancient plant has been waiting for its long-lost mate. The only known specimens of Encephalartos woodii, a rare and ancient species of cycad, are male, all clones of the same plant found over 100 years ago deep in a South African forest. Now a team of researchers is on a mission to find an elusive female version of the plant with the help of drones and artificial intelligence. In this episode we speak to Laura Cinti, a research fellow at the University of Southampton in the UK, about her determined quest to save the species – called the world's "loneliest" plant. The story in this episode came out of our series Plant Curious, exploring scientific studies that challenge the way you view plantlife.

An epidemic of mpox in the eastern Democratic Republic of Congo, is spreading quickly, particularly among young children. Mpox is a serious, at times fatal, virus – and the world knows how to prevent it. There are effective vaccines stockpiled in many western countries. Yet, after an earlier global epidemic in 2022 was largely brought under control in Europe and North America, the ongoing battle to protect people in Africa from mpox was ignored. In this episode we ask a virologist and a paediatrician why Africa's mpox crisis was so neglected and what needs to happen now to save lives, particularly children's. Featuring Nadia Adjoa Sam-Agudu, professor of paediatric infectious diseases at the University of Minnesota in the US and Wolfgang Preiser, head of the division of medical virology at Stellenbosch University in South Africa, with an introduction from Nadine Dreyer, health and medicine editor at The Conversation Africa.
