Paying peer reviewers works. Expanded Fast & Fair experiment @biologyopen.bsky.social: • 5.5 vs 37.7 working days to decision with reviews • ~3 vs ~9 reviewer invitations per manuscript • no reduction in editor-assessed review quality • similar acceptance rates www.biorxiv.org/content/10.6...

The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes: 🖌️ Dozens more images with duplications or painting 🖨️ Hundreds of blots that all share the same background (behold slideshow below)

Group leader Miguel Leung has been awarded the Young Scientists Award 2026 from @heinekenprizes.bsky.social . With his group, he investigates the 3D structure of protein complexes, tiny machines at work inside each of our cells. Congratulations, Miguel! Read more: www.hubrecht.eu/heineken-you...

We're happy to announce our new preprint! 🐸 easymode: general pretrained networks for cellular cryo-ET. Segment ~20 cellular features – ribosomes, microtubules, mitochondria, nuclei & more – with zero model training. 🔗 doi.org/10.64898/202... 🧵👇

1/I was preparing this slide for my annual doctoral school report presentation, and I thought it was worth sharing here: For a long time, I struggled to align my cryo-ET tilts for the Golgi better, but in the end, it was unsuccessful. For some reason, even though I had good data on tomograms without

2/Golgi for those with Golgi, I wasn't able to align. I tried different methods. Until very recently, that “missAlignment” pipeline was out. It is honestly a game-changer for my project. I hope that you can appreciate the improvement in the quality of the example tomogram I shared as well.😌 #CryoET

The manchette is a transient microtubule (MT)-based structure that is vital for the correct shaping of sperm during spermiogenesis. Throughout spermiogenesis, the manchette retains structural integrity for several days, raising the question of how its MTs are regulated. Here, using cryo-electron tomography of manchettes isolated from rat testes, we find that manchette MT ends are structurally diverse. We show that the MT-binding protein CLASP2 is present throughout the manchette and likely regulates both MT ends. Using cryo-electron microscopy single particle analysis and super-resolution microscopy, we reveal that SPACA9 and MNMIP1 (SH3D21) bind to the seam of manchette MTs from the luminal side. SPACA9 binds to both α- and β-tubulin of protofilament 1 but does not interact directly with protofilament 13, while MNMIP1 binds directly to protofilament 13. MNMIP1 further extends and threads through the MT lattice at the seam. Our study reveals a novel seam MT inner protein complex with a unique binding mode, providing a plausible explanation for MT regulation that maintains manchette integrity over an extended period.
