Within just a few years, the Chinese government's policy towards the Uyghurs deteriorated sharply. From control and marginalisation, it shifted to violation of human rights. PhD candidate Elke Spiessens was right in the middle of it with her research. 'The fabric of the community is being completely…

For the Bachelor Honours Class 'Mass Extinction', students produced podcasts about the past, the present and the future of mass extinctions. What exactly is lost when a species goes extinct? What are the practical consequences? But also: does humanity have the moral duty to protect other species?
