While researchers have usually modeled complex systems as networks of one-on-one interactions, recent advances in higher-order networks allow them to also describe groups of three or more units. However, this added complexity isn't always necessary. (1/2)

When should we favour a model with higher-order interactions over classical pairwise ones?

While we’re banning apps, Microsoft Teams is right there.

Completely agree! If we admit that online forums at this point are a necessity, there should be (at least) a public-funded/owned alternative to make online discussion basically a citizen right with citizen control over it

A great 2-yrs coll. with @federicomalizia.bsky.social, @santiagolaot.bsky.social, M. Frasca, V. Latora & @gomezgardenes.bsky.social

I teach a network science class where students create a short video to present their final project.

This one blew my mind and restored my faith in humanity!

(I recommend watching with sound on!)
