[Subtitles available in English] Do you remember when you were thinking about studying science or not? Were there other things that you also love and have to give up? At what age did you know that science was your thing? CNIO & The City presents ‘Changing the World’ to remember the sensations that accompany us in these decisive stages of our lives and to reflect the importance of knowledge co-creation and transmission. CNIO & The City is the educational and Science Outreach CNIO project which has the support of the Spanish Foundation for Science and Technology – Ministry of Science, Innovation and Universities.
