German Fish Meeting webpage coming soon with all fish models! Special postdoc session by @mads100tist.bsky.social + lunch meet-up with the 3 keynotes. We also hope to welcome participants from France, Switzerland, Austria and more Updates here or on @rastapopolus.bsky.social
"All That’s Left of You" is among the movies you should absolutely watch to better understand what’s going on in the Middle East and stop believing everything mainstream media tells you.

At the German Fish Meeting in Heidelberg (Sept 16–18, 2026), we’re excited to host a special session for postdocs transitioning to independence, animated and chaired by @mads100tist.bsky.social. PhD students will select the best talk to receive a prize. Looking forward to seeing you in Heidelberg!

Conservation of dark CPD photolyase function in blind cavefish - Nature Communications
By investigating the paradoxical retention of a photolyase gene in a light-deprived blind cavefish, the authors reveal a novel light-independent function for CPD photolyase in the repair of oxidative ...

Dear Jacob, I believe that better days will come, because every tyranny and dictatorship eventually collapses, precisely because they are built on injustice and the oppression of some over others. Stay strong and safe Azizi!!!!.
1/n Dear friends, in light of the current events in Palestine and to help spread awareness, a large number of filmmakers have made their FILMS about PALESTINE AVAILABLE FOR ONLINE FOR FREE
Below, we are sharing links to films that you can watch and share to spread our message to the world:
