Multiscale feedback drives viral evolution and epidemic dynamics
We introduce a minimal multiscale framework that links within-host virus dynamics to population-level susceptible-infectious-recovered-susceptible (SIRS) epidemiology through explicit, bidirectional c...

Thanks Sergi!
Sergi Valverde@svalver.bsky.social · last yr.Congratulations, Blai Vidiella (@blaividiella.bsky.social), on being nominee for the FRCCS Thom Young Research Award 2025! Blai is an exceptional complex systems researcher and one of my most valued collaborators. iutdijon.u-bourgogne.fr/ccs-france/t... #EvoBio #Ecology #ComplexSystems
Exciting paper from Sergi showing similarity in the scientific progress and the technological evolution! 🧪 #EvoBio
Sergi Valverde@svalver.bsky.social · last yr.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: 🧵

Structural Changes in Gene Ontology Reveal Modular and Complex Representations of Biological Function
Abstract. The Gene Ontology (GO) is a central resource for representing biological knowledge, yet its internal structure is often treated as static—or as a

Again, face to face with chaos. Now in a simple non-autonomous model with cooperation and habitat loss. Working hard in the manuscript !

How can biological systems anticipate future events? In our new paper with @jordiplam.bsky.social, we show how a simple genetic circuit can predict future trends through a simple (and perhaps widespread) mechanism @drmichaellevin.bsky.social @koseskalab.bsky.social www.biorxiv.org/content/10.1...

Metabolic early warning signals of epigenetic tipping points under chromatin modifier competition
The maintenance of epigenetic landscapes (EL) requires the precise regulation of chromatin-modifying enzymes (ChME). Competition for ChME can lead to degradation of ELs, triggering large-scale changes...

Another day, another funky gene regulatory network behaviour! In our latest paper, we show how the mushroom bifurcation can encode an ultra-long biochemical timer. Even more interestingly, extrinsic noise can be used to improve timing precision! 🤯 @mathsmaret.bsky.social @josepsardanyes.bsky.social
