During the Noorderzon Festival, Marthe gave a lecture on ‘The various faces of sugar’ at the event Noorderlichten, organized by the Young Academy Groningen. Noorderlichten was a 5-day event that included scientific activities and experiments for children during the day, and four mini-lectures for adults every night, where the audience was wearing headphones. In Marthe’s interactive lecture, people were taught about the molecular structure and sweetness of sugars, their (unexpected) addition to food, and learned about ‘good’ and ‘bad’ sugars.
