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)

Thank you so much Beth!! I miss you all too!! It's such a pity that travel is not possible.

Awww there's nothing to thank me for! You're an inspiration!!!

Eugenics is on the rise again: human geneticists must take a stand Scientists must push back against the threat of rising white nationalism and the dangerous and pseudoscientific ideas of eugenics.

“If left unchallenged, a rising wave of white nationalism in many parts of the globe could threaten the progress that has been made in science — and broader society — towards a more equitable world,” writes Genevieve Wojcik in a Comment article for Nature. 🧬 🧪
