There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd. It's not just budgets but research, institutions, expertise, and training the next generation.

Nice work by the Kurumizaka Lab in @natcomms.nature.com Multiple structures of RNA polymerase II isolated from human nuclei by ChIP-CryoEM analysis www.nature.com/articles/s41...

1/ New preprint! How do transcription factors (TFs) use intrinsically disordered regions (IDRs) to find their target sites? www.biorxiv.org/content/10.1... #TranscriptionFactors #IDPs #SingleMolecule #Biophysics

Super cool work on the function of intrinsically disordered regions in regulating transcription factor DNA binding.

The energy landscape of a single disordered protein (tau) and the impact of PTMs is resolved. An important step to understanding the function and dysfunction of disordered proteins from their conformational ensemble. Not yet peer reviewed. www.biorxiv.org/content/10.1...

How to find Evolutionary Conserved Enhancers in 2025? 🐣-🐭 Check out our paper - fresh off the press!!! We find widespread functional conservation of enhancers in absence of sequence homology Including: a bioinformatic tool to map sequence-diverged enhancers! rdcu.be/enVDN github.com/tobiaszehnde...

And, again, WHERE IS #BIGPHARMA in defending #basicscience? laying low? playing dead? Waiting it out? Do SOMETHING! SPEAK UP! Use your gigantic lobbying machine to defend us instead of peddling your wares and increasing your profits. Or do you think highly trained workforce grows on trees?

Wow - this is also the cofactor for the lyase activity of Cyp17A1 - required for production of androgens from pregnenolone/progesterone.

Did you know that there is an enzyme called ATAC, which is not related to ATAC-seq? :) academic.oup.com/nar/advance-... This paper reports a very interesting finding that ATAC and SAGA increase TF binding to DNA target sites on nucleosome by an order of magnitude independent of histone acetylation

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪
