Anna Lintunen had the pleasure to participate and give an invited talk in the IPCHS2021 seminar that was organized online in December 2021 (https://12thipchs.wixsite.com/home). During the seminar week, all the participants visited the conference area online as little avatars. They were able to walk around, chat with people and listen presentations at different sessions. Also daily live sessions were organized online. The topic in the talk that Anna gave was tree water dynamics and gas bubble formation in xylem under freezing conditions. She had many interesting discussions with other participants related to freezing behavior of trees and its consequences. And most importantly, she got new ideas for further research and collaboration. Thank you for the organizers!
