Keys to Bioethics is an app that provides users with a virtual bioethics manual. It is tailored to young people and is available in Italian, Spanish and English. The manual consists of questions and answers to fundamental existential questions related to: the development of the human being starting at conception, sexuality and gender, illness and death, abortion and research on stem cells, euthanasia and organ transplants. The project was carried out by the Dicastery for Laity, Family and Life in collaboration with the Jérôme Lejeune Foundation and presented at the World Youth Day in Panama 2019.
