In this series of podcasts we consider the impact of opening up science: allowing both the research community and the public to freely access the results of scientific work. Individuals can be fully informed about medical or environmental research, students worldwide can get access to the latest work, and software agents can roam the vast scientific knowledge base seeking patterns and correlations that no human has observed. Ultimately, it may profoundly change the way science is done. The resources are released under a Creative Commons licence - see end slide for attribution.
