“For four decades, the United States has run one of the most profitable trades in the world economy… import young people that the global labor market has underpriced—graduate students whose ability outruns their résumés—give them a place to prove themselves, and keep much of the upside”

A sobering, clear assessment in @pnas.org of the current US policy of international student exclusion. "The damage would not end with academic careers. A discovery becomes a vaccine, a company, and an industry only when someone commercializes it, and that work runs on the same imported talent."

Our paper on the subcellular proteome of Paulinella is finally out! A possible oxygen-scavenging mechanism to enhance RuBisCO carboxylation highlights how protists can reveal unexpected solutions to challenges in photosynthesis. Big kudos to everyone involved! @evanowack.bsky.social

A stress response can be a great starting point for discovering new biology! By following genes regulated during the chloroplast unfolded protein response, we’re discovering novel factors involved in chloroplast homeostasis. Here’s the first one we characterized: www.pnas.org/doi/10.1073/...

FYI there is no "real" reason why Rome "fell." Its power waned for the usual, mundane reasons: widening gap between rich and poor, inability to maintain infrastructure, incompetent leadership, pointless wars, endless persecution of marginalized groups who performed vital labor, etc.

Excited to share our latest preprint on #PhycologyFriday. We map out the carbon fixation pathway for the first time in a multicellular alga, the green seaweed Ulva, and reveal a unique Rubisco-Linker interaction in the pyrenoid, a chloroplast condensate. Below I summarize some key points. #seaweeds

1/7 New preprint: we found that Chlamydomonas carries a giant and unexpectedly elaborate chloroplast RNA polymerase with 12 previously unknown subunits, overturning the idea that the complexity of this organellar enzyme emerged during plant terrestrialization! www.biorxiv.org/content/10.6...

These little oases are entirely dependent on rainfall. The quillworts that live here have adapted by shortening their life cycle and shifting their growing season to winter and spring. Their spores mature in early summer as the pools dry out and plants enter dormancy.
