At this summer’s 64th Lindau Nobel Laureate Meeting, 37 laureates spent a week with 600 young scientists from almost 80 countries to share their ideas, experiences and knowledge. Discussions revolved around global health, the latest findings in cancer and Aids research, challenges in immunology, and future approaches to medical research. All of the lectures can be viewed on Lindau’s Mediatheque website.

Reporter Lorna Stewart was there for Nature Video to capture the unique spirit of the Meeting. In a series of four films, she asks both laureates and young researchers some of the most profound questions in medicine. The first film, HIV in hiding, highlights the research of Françoise Barré-Sinoussi who was awarded the Nobel prize for the discovery of HIV.

This is the second film: The long goodbye.

Growing old is inevitable and across the world average life expectancy is increasing. With the prevalence of age-related diseases following suit and a limited pot of resources, where should scientists be targeting research? In this Nature Video, superstar statistician Hans Rosling sets the record straight about the cause of the world’s ageing population and Nobel laureate Oliver Smithies, now 89, gives his opinion on medical research priorities. But when Lorna talks to young researchers, they disagree with the laureates on where scientists should be focusing their efforts.

Nature Outlook also produced a supplement based on the Lindau meetings.
