I'm thrilled to share our work from @JswLab ( https://t.co/CMzQznSXPN). We developed LOCL-TL, an optogenetic approach for monitoring localized translation in mammalian cells. LOCL-TL revealed two mechanistically distinct strategies for mitochondrially localized translation.

Thank you @ItaiYanai and the everyone for such exceptional workshops! It's valuable in expanding my perspectives and mindsets. These workshops are essential for researchers. I'll more enjoy the epiphanies and mystic encounters in my contradictory data now 🐘☕!
Night science is improvisations, openness, import/export, puzzle switching, hypothesis liabilities, metaphors/analogies, finding questions, contradictions & awe in science; as we discussed yesterday in the legendary Karolinska Institute. 🙏@Katrinardottir @chris_zie @sandberglab
