Finally!!! I’m astonished how so many—especially the educated—stay silent while authoritarianism rises and our freedoms shrink.

Five more journalists killed in a #Gaza hospital today. The toll is now 200. And in our so-called democracy, silence.

#zebrafish genome update from Shawn Burgess

Shawn Burgess @burgesslab.bsky.social · Aug 15

#zebrafish genome update, our T2T assembly of the inbred strain of AB (M-AB) generated by my buddy Nori Sakai has now been released at NCBI and will be a second reference genome for zebrafish (GRCz12ab):

Blind cavefish still keep an ancient DNA repair trick — even in total darkness 🌑🐟 New Nature Communications study from Nick Foulkes & team @ IBCS, KIT: "Conservation of dark CPD photolyase function in blind cavefish"
doi.org/10.1038/s414...

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 ...

Congratulations to you and your team

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:

I believe some Israeli scientists are beginning to react to what's happening in Gaza to avoid losing financial support from the European Commission.

Sepand Rastegar @rastapopolus.bsky.social · Jul 28

What can we expect when the majority of Israelis still support Bibi and his criminal gang? Sadly, Israeli scientists are often not much different from the general population. It’s a harsh reality.

Beautiful, enjoy 🫶

The world is truly insane!!! A war criminal is supporting a narcissistic politician who incited his supporters to attack the U.S. Congress—for the Nobel Prize. This is the most ridiculous joke ever.

Sepand Rastegar @rastapopolus.bsky.social · Jul 9

This is what we are usually doing too. Often the rebuttal letter are so long that even we do not remember what was exactly done.

Sepand Rastegar @rastapopolus.bsky.social · Jul 9

After 2 intense months and a 42-page rebuttal (!), we’ve resubmitted our revised MS: “Multiple cis-regulatory elements collaborate to control mdka expression in telencephalic neural stem cells of adult #zebrafish.......” Soon on
@biorxivpreprint.bsky.social — stay tuned!
