Really happy to see this out, done during my wonderful visit to @lhd.bsky.social in Vermont🍃🍁❄️ Including temporal group dynamics in higher-order contagion reshapes the phase portrait, and when using features from real-world data, multistable active phases emerge naturally 🤩🤩

🚨 🚨 How do group dynamics shape contagion onsets and multistable active phases under collective reinforcement? 👉 arxiv.org/abs/2603.28566 @santiagolaot.bsky.social @federicomalizia.bsky.social @leahkeating.bsky.social @gstonge.bsky.social V. Latora @gomezgardenes.bsky.social & @lhd.bsky.social

🚨 New preprint showing that viral evolution 🦠 leads to superexponential growth 📈 and, as a consequence, challenges control policies, potentially worsening outcomes vs no action 👉 arxiv.org/abs/2603.18801 @santiagolaot.bsky.social A. Arenas @gomezgardenes.bsky.social & @sorianopanos.bsky.social

We are excited to see our work featured on the cover of @commsphys.nature.com! “Genotype networks drive oscillating endemicity and epidemic trajectories in viral evolution” by @gotham-lab.bsky.social. What a cool thumbnail 😁

🚨🚨 ¡Atención! 🚨🚨 La IV edición del congreso FisEs Joven, un congreso online dedicado a jóvenes investigadores e investigadoras en física estadística, comienza hoy! Programa: fisesjoven26.gefenol.es

Here's another new article in @commsphys.nature.com, this time about higher-order interactions! We demonstrate that sparse group-based interactions, which are commonplace in today's digital societies, promote social polarisation. This is especially relevant given the current tense situation.

No os perdáis el FisEs Joven! El mejor congreso para conocer la investigación de los jóvenes investigadores 🏆

DEADLINE FISES JOVEN!!! Ampliamos el plazo para el envío de contribuciones hasta este viernes, 16 de enero. Toda la información disponible en: fisesjoven26.gefenol.es Si tienes cualquier duda, no dudes en escribirnos a [email protected]

1/6 And another article out in @commsphys.nature.com Sparse group interactions polarize…but dense group interactions moderate!! Polarization emerges as a structural effect of how groups are organized: www.nature.com/articles/s42...

I'm really happy to see this article being published! I find it very intriguing that the topology of genotype networks, which reflects the exploration of the antigenic space, can alone be enough to explain seasonality in epidemic trajectories.

1/7 🚨 New article out in @commsphys.nature.com We show that viral 🦠 evolution is best captured through complex genotype networks, whose topology alone can drive oscillatory endemic dynamics and epidemic variability: www.nature.com/articles/s42...

🚨🚨 ¡Atención! 🚨🚨 La IV edición del congreso FisEs Joven, un congreso online dedicado a jóvenes investigadores e investigadoras en física estadística, se celebrará los días 10, 11 y 12 de marzo. (1/2)

Really happy to see this out in PRX Life! There you can find an eco-evolutionary framework integrating the evolution of viral infectiousness and antigenic features. While the former determines contagion events among hosts, the latter tells us how quickly viruses can escape population immunity 1/4👇

¡Comienza la cuenta atrás para la IV edición de FisEs Joven! Este encuentro reúne a jóvenes investigadores en física estadística y áreas afines, fomentando el intercambio y la colaboración desde las primeras etapas de la carrera científica. (1/2)
