🚨🚨 New preprint just dropped! In collaboration with @colltoaction.bsky.social, Cliff Joslyn, @fralotito.bsky.social, Audun Myers, Joshua Pickard, Brenda Praggastis, and Przemysław Szufel, we define a new data sharing standard for higher-order networks. arxiv.org/abs/2507.11520

Alexandra Puchalska introducing pangraphs: in this case, hyperedges can also be nodes, and hypergraphs can also be nodes? 🤯🤯 wild times in network science.

Some beautiful results: sublinear consensus times for the higher-order voter model in comparison to linear in the pairwise case. With regard to a paper he found: "I used Google. I don't use GPT whatever" 🔥

Some really interesting results: overwhelmingly "redundant" architecture in the brain, but evidence for synergistic interactions, which typically seems to correspond to 0 Pearson correlation coefficient.

Unlike other higher-order dynamics (sync, contagion, etc.), where discontinuous transitions emerge when including 3-hyperedges, discontinuous transitions occur only when hyperedges of size 4 and larger are included (!)
