Ngā Wai Hono i te Pō ascends the Māori throne as the new Kuini (Queen), much to the joy of her people, heralding a new age of prominence for the Kiingitanga movement. We ask whether the new queen may have a biological advantage making her a better fit for leadership, whilst searching for examples of matriarchy in the animal kingdom and analogous human societies. As is customary, Ngā Wai Hono i te Pō was crowned on the same day as her father’s funeral, thrust into a leadership role during a time of profound grief. We hear from Prof Lucy Selman, expert in palliative and end-of-life care from the University of Bristol, and founder of the Good Grief Festival. She speaks about the physical and emotional manifestations of grief and how it can be processed and overcome, even in the face of immense responsibility. We remember the legendary voice of the late James Earl Jones, who played the intergalactic monarch, Darth Vader, as Marnie unpicks the science of stuttering. Unravel a massive jigsaw puzzle, uncover a hidden secret behind Queen’s hit song Don’t Stop Me Now, and delve into the fascinating realm of neuroscience and much more on Unexpected Elements.
