We report a human cell-free translation screen that identified NT-2, a Fusarium mycotoxin that blocks human ribosomes. The surprise: NT-2 does binds the ribosome and pushes them into a dormant state. www.nature.com/articles/s42...

@nbellono.bsky.social and colleagues observed that Elysia sea slugs steal chloroplasts from algae and store them in specialized organelles called kleptosomes. During times of starvation, this allows them to photosynthesize in support of their energy needs! 🧪 www.cell.com/cell/abstrac...
Graphical abstract of the linked paper.

Sea slugs retain and store foreign chloroplasts in kleptosome organelles (top). Kleptosomes use luminal ATP-sensing ion channels to support photosynthesis (bottom left). Kleptosomes digest chloroplasts during prolonged starvation (bottom center). Slugs and corals use convergent mechanisms of endosymbiosis (bottom right).
