Our morning session started with talks on the open science ecosystem from Tobias Wenzel & Hernán Grecco. Both speakers emphasised the importance of training. Quote of the day so far, “By democratising science, we strengthen democracy!”

Dina Arvanitis @camatnu.bsky.social presented fluorescence microscopy 101, discussing the pros and cons of different methodologies. Take home messages: fancier microscopy ≠ better research; think NA, NA, NA!

So humbled and grateful for this opportunity, but want to emphasize that none of this would be possible without @marianadeniz.bsky.social who not only had the idea and did the work for the nomination, but saw in me something that I did not. It has been an honor to work with and learn from her. (1/2)

Now that I can say it publicly - huge congratulations to @michelleitano.bsky.social , winner of this year's @bioimagingna.bsky.social Michael W Davidson award for "Community contributions, in any of the areas of Engagement, Education, Mentorship, and Standardization". So well deserved! #GBIxBINA2025
