Our work on #hornwort #pyrenoids is finally out in @science.org! 🎉 We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...
Apply now! @vbcscitraining.bsky.social offers more than 25 fully-funded PhD positions! GMI group leaders are also recruiting new students.
Interested in the most recent developments in plant science? Join the Mendel Early Career Symposium on May 21-22 at the @viennabiocenter.bsky.social to exchange with experts about their science and career trajectories. Register by March 13th for a talk. More here: www.oeaw.ac.at/gmi/news-eve...
@embl.org at its best: collaborative, open, transformative, and just the right amount of crazy. Dreaming of mechanistic cell biology *in the natural environment*? Dream no more, rent the AML.

Long in the making, but happy to present the Chlamydomonas chlororibosome!
Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins.
bioRxiv 📖: shorturl.at/q44tG
This suggests greater chlororibosome diversity than expected!

What a great collaboration this has been!
How does molecular valency shape condensate assembly and function? We used the CO2-fixing organelle in algae—the pyrenoid—to find out… 🧵

How do diatom cells maintain a constant supply of carbon for photosynthesis? Our microelectrode measurements of the phycosphere around individual diatom cells show that diatoms can rapidly switch between distinct carbon acquisition pathways. @thembauk.bsky.social www.science.org/doi/10.1126/...

Researcher Florian Wollweber standing next to a cryo-focused ion beam microscope in a laboratory, with technical infrastructure visible in the background.
The origin of eukaryotic cells continues to be one of the greatest mysteries in biology.
EMBL Grenoble is excited to welcome Florian Wollweber, who will use cutting-edge imaging techniques to study Asgard archaea — microbes closely related to our earliest ancestors. 🦠🔬

Poster of the EM course in Naples with marine samples. The Electron Microscopy Hands-On Course: sample preparation and imaging of marine environmental samples arises from a very strong and active collaboration between the Stazione Zoologica Anton Dohrn and the EMBL in Heidelberg. The aim of the course is to provide a theoretical and practical training on electron microscopy starting from the basics to the preparation of samples with high pressure freezing and image acquisition using TEM and SEM.
If you are interested in electron microscopy, registration is still open for the
"Electron Microscopy Hands-On Course: sample preparation and imaging of marine environmental samples"
at Stazione Zoologica in Naples.
WIth great teachers from Naples […]
