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)
We are hiring POSTDOC now!🚨please repost! Fully-funded 5-year position 👩🏻🔬👨🔬🧬Looking forward to your application!✉️

We're on a roll here. Check out this cool paper by @scienceleah.bsky.social et al. on not one, but two types of sperm (!) in the silk worm Bombyx mori. Happy to have contributed. #meiosis4ever
Now in Nature Comms w/ @ritatewari.bsky.social, Pushkar Sharma & @ryanase.bsky.social (thanks!). Aurora kinases fascinate me: single ancestor - parallel duplications in eukaryotes - paralogs with distinct functions. ARK1 is the CPC Aurora in the malaria parasite. rdcu.be/e5NRT #plasmodium #mitosis

Check out our first lab preprint: A real team effort to understand the Plasmodium GAPM proteins, which form part of a essential bridge between the parasite's cytoskeleton and motility apparatus. Below is a sneak peek of some beautiful microscopy - light and electron! www.biorxiv.org/content/10.6...
Happy to see our work on defining a dependency map of short linear motifs out. We use base editing screens to install more than 80000 mutations into SLiMs in more than 4000 proteins to determine their contribution to cell fitness. www.nature.com/articles/s41...

New preprint! We identified many components that localize to the structure involved in "eating" in a marine organism.

As a cell biology lab, we acknowledge the decades-long impressive efforts to uncover evolutionary relationships using advanced phylogenomics methods. These approaches undergo continuous improvements that lead to adjustments of data interpretation, as is the case in every scientific field. (1/3)

Before he passed away in 2021, Tom Cavalier-Smith had drafted parts of his autobiography. It's now 'published' because Gáspár Jékely put a lot of effort in! Please enjoy and share: doi.org/10.5281/zeno...

Nature Communications - This study reveals that the malaria parasite Plasmodium uses a unique Aurora kinase complex to control cell division. This divergent machinery regulates spindle formation...
Duplicated self-interacting proteins can interact and interfere with each other’s

New work on ARK1 (AURKB?) in Plasmodium (malaria parasite) with @ritatewari.bsky.social and Pushkar Sharma. CPC in Plasmodium is (ofcourse..) different compared to conventional models: two INCENPs, no borealin/survivin - mainly at spindle microtubules/MTOCs. Special thanks to @ryanase.bsky.social!

New paper from the Rosin lab in collaboration with the Hawley lab 🎉 Spearheaded by postdoc Leif Benner. We use imaging and RNA-seq to better understand apyrene meiosis.
Programmed meiotic errors facilitate dichotomous sperm production in the silkworm, Bombyx mori.

BTW when I talked to a cell biologist this week and explained that bacterial-origin proteins were used to determine the root of the eukaryotic tree of life, the person was surprised by that approach. So it's not just me who has issues with this approach.

Pleased to share our new preprint: "Plasmodium ARK1 regulates spindle formation during atypical mitosis and forms a divergent chromosomal passenger complex". Many thanks to our collaborators.
