#MembraneTraffickers! Our next online seminar is this Thursday, Nov 6 at 5 PM CEST! We’ll hear from @agatawitkowska.bsky.social on mechanical control of neurotransmission and @abdourachidthiam.bsky.social on lipid storage mechanisms in health and disease. Spread the word and join the discussion!

I set out to review the evolution of eukaryotic intracellular traffic, but along the way a new hypothesis came into focus: maybe the earliest membrane carriers were tubules, not coated vesicles! New preprint: ecoevorxiv.org/repository/v... Here’s the idea. 🧵

A very Happy 2025 to all here and outside.
