Someone in the news departments of @nature.com or @science.org needs to take a look at this--its a huge scandal from the scientific supplier that has become a monopoly

How do sperm and egg fuse? Surprisingly, we still don’t fully know… Our field has uncovered many pieces of the fertilization puzzle, but not how they fit together. We identify ✨ SPARK ✨ - a conserved sperm complex that couples sperm-egg binding to fusion. tinyurl.com/34cm4xat Read on! 🧵👇

@johanduchene.bsky.social @sholtodavid.bsky.social Spent the last hour looking, found ten more apparently manipulated Western blots in Thermo Fisher's antibody verification data (across eight different catalogued products). Thread below. www.thermofisher.com/antibody/pro...

Taxol exploits molecular switches within tubulin to stabilize microtubules. https://www.biorxiv.org/content/10.64898/2026.05.17.725690v1

Surprised to discover that Thermo Fisher appears to show a fake western blot for the validation of one of their p53 antibodies. I've added a diagram to show the very similar bands. This does not appear to be one of the "published figures" but their own internal data.

wow — the preprint host, arxiv, is banning authors for a year if they submit papers with hallucinated citations 🤖

The cartwheel was first visualized ~70 years ago in the symbiont Trichonympha in the wood termite gut. We’ve discovered the cartwheel’s secret: a unique zigzag stacking of SAS-6 tetramers that facilitates the iconic 9-fold symmetry of cilia. #cellbiology #teamtomo #SAS6 #cartwheel
