Loved this short note from @giulioburgio.bsky.social arxiv.org/abs/2610.08712 This makes a point I had not yet seen. Beyond overselling or the reinvention of old models, some like the language of hypergraphs because: Directed hypergraphs capture the structure of dynamical models in a unique way.

Keeping the interaction structure explicit: comment on ''Graphs are maximally expressive for higher-order interactions"
Peixoto et al. (arXiv:2602.16937v2) stress that graph-based formulations can express any interaction model, a point the literature on higher-order networks (HONs) has often overlooked. We agree with m...

New preprint from the lab: The Latent Simplicity of Microbial Ecological Interactions www.biorxiv.org/content/10.6... We're excited about this one. We find that high-order microbial interactions often obey simple linear laws making microbial communities far more predictable than one might expect

New preprint from our lab Statistical learning of bacterial growth in combinatorially constructed environments, led by brilliant PhD student Andrea Arrabal. www.biorxiv.org/content/10.6... We systematically study nutrient-nutrient interactions in bacterial growth under carbon-limiting conditions.

New preprint on the limits of detecting higher-order interactions in microbial communities. www.biorxiv.org/content/10.6... We find that the dominance of additive and pairwise interactions on community function may not reflect biological simplicity, but fundamental limits of statistical detection.

Many are appropriately outraged by Altman’s comments here implying that raising a human child is akin to “training” an AI model. This is part of a broader pattern where AI industry leaders use language that collapses the boundary between human and machine. 🧵/

I hope people (speaking to myself) will talk more and more about higher-order interactions and less and less about higher-order networks.

p.s., we could not have proven the result above with a standard, node-based mean-field approx, since, in fact, it completely forgets about the interaction structure. For the same reason, it cannot discern repeated interactions with a same agent from a single interaction with many.

e.g., how interactions of different orders are distributed across the network (inter-order correlations) matters for contagions. This is true no matter the representation you choose. I just find easier to think about and communicate it in terms of HGs than BNs. journals.aps.org/prl/abstract...

Choosing one representation among several equivalent is about convenience, in this case to help intuition. Hypergraphs offer a "direct" representation of interactions; bipartite nets, less intuitively, map interactions to new nodes, but preserve a pairwise description and are more flexible.

Glad this piece is out! I never understood why some literature went obsessed with hypergraphs per se when a lot had already been done (and yet ignored) for bipartite nets. What's interesting about higher-order interactions is...🥁...interactions – not how they are represented.

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👇

Very cool interactive story, @jstonge.bsky.social! "[...] real social cascades aren't simply branching processes with fixed rules." A self-reinforcing mechanism is what we propose in a recent piece led by the one and only @lhd.bsky.social.

It might start as a joke, belief, or rumor, easy to dismiss. But then it twists, builds momentum, and spreads like wildfire. Why do some ideas die out while others go viral? A new study by researchers from the University of Vermont and the Santa Fe Institute offers answers: santafe.edu/news

There's amazing work on group effects in higher-order networks, but not a lot of connections to social ontology, collective action, and group selection. Led by @jstonge.bsky.social with expert guidance of @rharp.bsky.social we reviewed and formalized these connections. arxiv.org/abs/2507.02758

Not sure we'll ever understand adaptive systems enough. But what we're sure of is that one basic reason is that you can't even start to describe them properly w/o preserving local dynamical correlations. A fun and frustrating long way to go. w/ the amazing @lhd.bsky.social & @gstonge.bsky.social.

During a pandemic such as COVID19, we hope (but fail) to accurately estimate the incidence of the disease. In this paper, we propose a new approach to machine-learn models of the real incidence from readily available information (tests and detected cases) dx.doi.org/10.1371/jour...

Some decisions are best made quickly and locally. Governance can work better as a higher-order network, not a pyramid around a central state. How should we design these networks? We looked at this with law and complexity scholars and found "effective governance" networks. arxiv.org/abs/2412.03421
Cartoon of a top-down central state combined with a local network of decisions units.Cartoon of decisions as a statisfiability problem (decision network) where each decision is solved by a higher-order network (governance network) of agents with their own opinions on what decisions should be made.
