New preprint from the lab 🎉: γ-tubulin is a novel target of the tubulin autoregulation pathway! Previously thought to exclusively target α- and β-tubulin mRNAs, we show that the TTC5–SCAPER–CNOT11 axis also degrades γ-tubulin mRNA, expanding the scope of this fundamental regulatory mechanism.

This is the cover proposal I made for our recent paper!
It’s Pyramimonas diskoicola — a very beautiful green flagellate and one of those cells that makes you stop and stare for a while.
I tried to capture its shape, symmetry, and general vibe :)

This delicate sponge has a remarkably clever survival strategy.🪝✨️
Most sponges filter small plankton and bacteria from the water and pump them through their bodies. But the harp sponge (Chondrocladia lyra) uses small hooks along its vertical branches to trap and eat larger prey.
