To launch our brand new podcasting endeavour we decided to record during our Expo-sciences 2022 event that showcases the work of young scientists from Luxembourg and all the corners of the world. We briefly talked to our director, Sousana Eang, to then move to the heart of our event, the young scientists who were: Uri Sadan Yarchi from Israel, Rayene Frej from Tunisia, and Lynn Schneider, Theodor Stanica and Christopher Gargiulo from Luxembourg. This was an occasion for us to discuss nuclear fusion with cylindrical capsules, cleaning solar panels, creating bioplastic and energy production methods in Luxembourg. What a treat!
