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!

Resurrected nitrogenases recapitulate canonical N-isotope biosignatures over two billion years - Nature Communications The study shows that nitrogenase enzymes have maintained stable isotope signatures over billions of years, revealing how ancient microbes shaped Earth’s nitrogen cycle and offering a new experimental ...

Our new paper, out today! We resurrected ancient nitrogenases first used by life on Earth 3 billion years ago. We combined synthetic biology and geology & validated their chemical #biosignature in rocks that helps reveal ancient life on Earth!(and beyond!)

Researchers led by Jun.-Prof. Dr. Julie Zedler at #UniJena have developed a sustainable alternative to synthetic food colourings: they have modified cyanobacteria so that they produce yellow natural colourings from light and carbon dioxide alone.
