A mathematical model explains virus persistence and fading in cell cultures infected by HCV. As a novelty, the model distinguidhes between three diferent viral fitness traits: replicative, infective, and dispersive. More at: www.biorxiv.org/content/10.6...

Where are all the intermediate forms between animals & plants? Our new paper with @jordiplam.bsky.social suggests evolution can split sharply between sessile, photosynthetic and mobile, sensing strategies. If so, what does this imply for claims of plant intelligence? www.biorxiv.org/content/10.6...

The model combines a Boolean gene-level description with spatial dynamics. This has been a long journey that started five years ago with @guimaguade.bsky.social and @qmartib.bsky.social, developed by Gianluca d'Addese and @frazambelli.bsky.social and with the coll of @josepsardanyes.bsky.social.

Can the structure of knowledge evolve like life itself? In our new MBE paper, we show that the Gene Ontology evolves through mechanisms shared with cultural and technological systems—reuse, modularity, and curator-driven restructuring. Here’s what we found: 🧵
