Sharing things

In this episode, guests Charles Cockell and Rianna Walcott talk about woolly mammoths, deep sea gigantism, knowing your place in the family hierarchy and more. Charles is Professor of Astrobiology at the University of Edinburgh. His group focuses on the study of life in extreme environments and understanding the diversity, processes and biosignatures of life in extremes, and the potential habitability of extraterrestrial environments. Rianna is a PhD candidate at King's College London researching Black women's identity formation in digital spaces, and a graduate twiceover from the University of Edinburgh. Each episode of Sharing things is a conversation between two members of our university community. It could be a student, a member of staff or a graduate, the only thing they have in common at the beginning is Edinburgh. We start with an object. A special, treasured or significant item that we have asked each guest to bring to the conversation. What happens next is sometimes funny, sometimes moving and always unexpected.
