⚠️New genomic model for #coccolithophore biology: the haploid genome of Calcidiscus leptoporus! Its genome, resolved alongside six recurrent phycosphere bacteria, reveals a distributed B-vitamin network linking host genomic gaps to microbial capacity.

Not all nuclei are the same. We went to some of biology’s most exceptional nuclei 👉 dinoflagellates with genomes 80× ours 👉 Giardia’s twin nuclei 👉 ciliates carrying two nuclei in one cytoplasm & asked a simple question: what sets nuclear density? 🧵 Preprint: www.biorxiv.org/content/10.6...

🌊 We celebrated #CoccolithophoreDay at the Nikola Tesla Technical Museum in Zagreb! Our team from the Ruđer Bošković Institute brought the fascinating world of coccolithophores to life through microscopy, VR, puzzles and hands-on activities for all ages! 🔬 #ScienceOutreach #protistsonsky

Out today in @nature.com: our review on how single cells evolve into multicellular organisms. With Ozan Bozdag, @kaitong25.bsky.social, Peter Yunker, and @matthewherron.bsky.social. rdcu.be/9ZuiKow9twKa For an overview, check out the video below.

Peter Hegemann and Georg Nagel – awarded the 2026 medicine prize – discovered a remarkable protein, channelrhodopsin, in a single-celled alga. Hegemann wondered how Chlamydomonas, a single-celled alga, is able to swim towards a light source.
