African HIV research now makes up almost a third of total research being conducted into the virus. A new study highlights how it has increased from just 5 per cent in 1986. But there’s still a way to go until the quantity of research reflects the burden of HIV infections on the African continent. Claudia Hammond speaks to Professor Thumbi Ndung’u and Dr Omolara Baiyegunhi from the Africa Health Research Institute in South Africa about the future of research being conducted in Africa by Africans and why it matters.

Non-alcoholic fatty liver disease is now the fastest growing liver disease in Europe. It already affects 38 per cent of people around the world. We hear from Vienna in Austria where a mobile clinic is offering people liver scans, and specialists have been teaching school children about liver health.

Dr Ann Robinson joins Claudia in the studio to discuss the latest health research including a US study with good news for people diagnosed early with a skin cancer known as melanoma. And a simple reason why staying up late might mean you won’t live as long as someone who enjoys an early start to the day.

And who better to crunch the data on siestas than the President of the Spanish Federation of Sleep Medicine Societies. Dr Carlos Egea explains how the modern siesta is more about taking a short time to relax, rather than a long afternoon sleep.
