I discuss our current work disentangling misconceptions around "higher-order" networks: arxiv.org/abs/2602.16937
Explainer thread for the paper here: bsky.app/profile/tiag...
Really looking forward to reading this! I worked on bootstrap percolation on simple networks, and I always found it puzzling that hypergraphs were presented as necessary for modeling group interactions.
New on the arxiv:
“Graphs are maximally expressive for higher-order interactions”
arxiv.org/abs/2602.16937
We clarify central misconceptions in the recent literature on "higher-order networks".

🌍🚶 How much of our movement is about human choice and how much is constrained by geography and the spatial layout of locations?
Our paper (out in Nature Human Behavior) gives you a practical way to tell:

What if #herd_immunity isn’t just about how many people are immune, but how they’re 'spatially' connected? Our new PNAS paper explores this concept. We show how the topology and geometry of social networks influence the dynamics of herd immunity, whether it arises from infection or #vaccination. 1/2
How universal is the mean-field universality class for percolation in complex networks?

Most neuroscience research is exploratory: they search for *something* rather than testing a hypothesis. It's harking. I used to see that as a problem, but not anymore. The 1st papers generate hypotheses; the real testing comes later. Science only make sense collectively, not individually.

Already back from São Paulo after 6 vibrant days lecturing in the School & Workshop about "Synchronization: from collective motion to brain dynamics". Thanks to the organizers and ICTP-SAIFR for such an amazing event!!
Below I post the videos of my lectures and the talk in the workshop.
El despropósito de retirar a Argentina de la OMS (y todo lo que va a seguir si lo dejamos) tiene que ser tomado seriamente. Los decanos de facultades de ciencias de la salud podrían actuar como voceros de una exigencia transversal de parar esta locura.
La salud no entiende de fronteras ni ideologías. Nadie está a salvo si no estamos todos a salvo.
Redoblamos nuestro compromiso con la OMS, que ha sido fundamental para la erradicación de enfermedades, la lucha contra pandemias y el acceso global a la salud.
