Nematode towers that you can get to grow in lab using C. elegans. Maybe a new, tractable model system for studying self-organization in the lab. 🧪

Towering behavior and collective dispersal in Caenorhabditis nematodes
Perez et al. report that self-assembling nematode towers occur in nature and can function
as collective dispersal structures. Using Caenorhabditis elegans, they establish a
tractable empirical model t...

Check out the beautiful work of my colleagues Meghana and Marco! It showcases how transcription independent propagation (!) of an active chromatin mark is essential for faithful ZGA
✨ Excited to share my latest preprint on how H3K4 methylation promotes transcriptional memory from gametes to embryos across a transcriptionally silent window — crucial for proper zygotic genome activation and development. 🐸🧬✨

H3K4 methylation-promoted transcriptional memory ensures faithful zygotic genome activation and embryonic development
In the life of a vertebrate embryo, gene expression is initiated for the first time at zygotic genome activation (ZGA). Maternally expressed transcription factors present in the embryo are essential f...
