Public Engagement: "Licence to Stress" at Edinburgh Science Festival
April 2026
On 13 April, Dr. Mark Nixon and a team of researchers put on an event, 'Licence to Stress', as part of this year's Edinburgh Science Festival. Using a spy theme to illuminate the science, the event showcased BHF-funded research on the stress hormone cortisol and its effects on our health. This was an opportunity to challenge the idea that cortisol is purely harmful, showing it instead as part of a vital system that only becomes problematic when pushed too far.
The event, which took place at the University of Edinburgh's Bayes Centre, included a talk and Q&A session with Mark, followed by activities to help attendees get to grips with the science, which were run by Mahnoor Asif, Doanne Chin, María Paula Huertas, and Dr Giovanni Levatè. Preparations in the run-up to the event and on the day were supported by Ed Dadswell.
The event proved to be popular, with all tickets sold out, very positive feedback, and many participants eager to ask questions and talk to the scientists about their work. Attendees described it as "interesting and engaging", "very accessible for non-scientists", and commented on the "excellent imaginative presentation" and how they "loved the metaphors and graphics to make tricky subjects easier to understand".
