The KEY🔑 to regulating Rubisco phase separation in the Chlamydomonas algal pyrenoid. Beautiful work by Shan He, @mjonikas.bsky.social, and friends. #PhaseSeparation #CO2 #PlantScience 🧪 🧶🧬 🌾 🌍

Martin Jonikas @mjonikas.bsky.social · 20h

Algal pyrenoids—condensates that mediate ~1/3 of Earth’s CO2 fixation—change size and number as cells divide. Our data suggest a simple control mechanism: a kinase that continuously ejects material from the condensate! ☀️🌍🔬💧 #Biophysics #Photosynthesis

What happens when the cell's powerhouse gets stressed out? 💪🥵 Great visualization in this #Mitochondria #TeamTomo study! Congrats @denkenny.bsky.social @ruferbus.bsky.social & crew 🧪 🧶🧬 🔬

Kenneth Ehses @denkenny.bsky.social · 4d

✨Excited that the main project of my PhD is now available as a pre-print on #bioRxiv

Here, we used #CryoET to visualise mitochondrial proteostatic stress and together with SPA #CryoEM shed light into the functional cycle of the Hsp60:10 chaperone system. #TeamTomo

Out in Science Advances: Our #cryoEM structure of HFTV1, a virus infecting the halophile #archaea. *First full atomic structure (containing all structural proteins) of any tailed virus!* Congrats and thanks to all co-authors and our fantastic collaborators! www.science.org/doi/10.1126/...

Cryo-EM resolves the structure of the archaeal dsDNA virus HFTV1 from head to tail

This structure of an archaeal tailed virus (arTV) provides detailed insights into arTV assembly and infection mechanisms.

#TeamTomo ❄️🔬 meets #MassSpec Imaging 🧬🔬. Super cool, and great potential for EM grids with mixes of different cell types. For example -- environmental samples! @embltrec.bsky.social 🌍 🧪

Jakob Meier-Credo @meiercredo.bsky.social · 23d

Check out our new preprint on an integrated pipeline combining in situ #cryo-ET with MALDI #MSImaging for single-cell identification and classification from previously analysed EM-grids.

Can they make eggs from male skin cells? Or sperm from female skin cells? Now that would be interesting….

I think it has something to do with conservative lawmakers taking aim at liberal-leaning social media. See this announcement that my friend got. Did you get something similar? X is not affected by this law, and that place is swarming with misinformation and porn bots. No free speech = Hot Garbage 🔥🗑️

But there’s a curious loose end to this story. Scientists have been looking at PSII organization in thylakoids for over 50 years (including some really stunning freeze fracture 🔬😍). Sometimes PSII looks randomly oriented, and other times it forms extended 2D crystalline arrays in the membrane 💠

Love it! 🧪🤓 Ya know, thylakoids can also play this paracrystalline lattice game. In plants, they emerge from the prolamellar body during de-etiolation 🟡➡️🟢

An interesting parallel: Rod outer-segment disk membranes are highly packed with a membrane protein (rhodopsin) 👁️, similar to the stacked domains of thylakoids (PSII-LHCII) 🌱. And isolation of disk membranes may cause rhodopsin to crystallize into 2D arrays 💠
