Sailing in @biorxivpreprint.bsky.social ready for summer, our study on the iconic Portuguese man o' war 🪼 is out: www.biorxiv.org/content/10.6.... We use (epi)genomics to understand a critter that fascinates me since childhood. Massive team effort with @obog.bsky.social, Cummins and Neely groups. 🧵

Integrative genomics of the siphonophore Physalia utriculus reveals the regulatory logic of colonial division of labour and the molecular basis of venom activity
How a single genome gives rise to specialised multicellular individuals that function as an integrated organism remains a fundamental question in the evolution of complex coloniality. Siphonophores re...
