Super excited to share my postdoctoral work at @imbavienna.bsky.social @viennabiocenter.bsky.social - We discovered that some retrotransposons, or "jumping genes" 🧬, are able to spread from cell to cell via a new viral infectivity route. A short thread: 🧵👇 (1/7)

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! 🧵👇

Hot take, pls hear me out: rather than single manuscripts, imagine single self correcting monographs per long term topic in a laboratory, version controlled like a GitHub repository, where additions are tracked with author lists to give credit. Peer review of the monograph addition. Could this work?

Initial attempt at replicating in relion (parameters in next post). This is for Aca2-RNA, using a 100k subset of the 2D-classified particles (no prior 3D cleanup). A 1-class ab initio in relion, then local refinement in relion (1.8deg searches+blush) gives a nominally 3.3Å map; 3.5 Å w/out blush.
