72 hours. 7 teams. 7 new preprints. 🚀 The 2026 Complexity 72h Workshop brought researchers together in London to tackle complex systems questions, and produce a paper in just three days. All seven preprints are already on arXiv: tinyurl.com/v9xtrva6 Congrats to all participants and the NetSI team! 💯

🏆 Congrats to all winners! 🎉 🗣️ People’s Choice Award Best Presentation 🎶 Natalia – Best Complexitune ❤️ 🏅 Complexiads 72m – Best Individual & Best Team And yes… Best Team also got People’s Choice 😂 Mens sana in corpore sano Thanks all for the amazing energy at #Complexity72h 💙

The clock is ticking and the end of the 72h is drawing ever closer 😱 While ideas take shape, models evolve, and final presentations come together, here’s a glimpse of each team as they race towards the finish line 👥🧠🏭📚🗳️🤖🏀

The essay was never just words on a page. It was a promise. My new post, "The Student Who Wasn't There," is about what AI does to that promise, and how to keep it. baronca.substack.com/p/the-studen...

⚓ Almost there! #Complexity72h London starts next week: 80+ researchers, 8 projects, 72 hours. Looking forward to welcoming everyone to Northeastern University London! @complexity72h.bsky.social @nunetsi.bsky.social

Quest’oggi arriva in edicola il numero di maggio de Le Scienze. Al suo interno, trovate un mio articolo sulla Network Science. Dal modello di Grafo Aleatorio fino agli HONs, passando per leggi a potenza, epidemie e network temporali. Disponibile anche al link 🔗: www.lescienze.it/riviste/2026...

Our lab is looking to fill a post-doc position to do research on human-AI interaction. More details here www.christophriedl.net/jobs.html

How complex should network models be? 🚨 In our latest paper we quantify (if and) when higher-order interactions are informative versus reducible to pairwise structure without losing functional signal (e.g., diffusion behavior). 👉 www.nature.com/articles/s41... 1/

In a brief 𝘕𝘢𝘵𝘶𝘳𝘦 𝘊𝘰𝘮𝘱𝘶𝘵𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘚𝘤𝘪𝘦𝘯𝘤𝘦 piece, E. Valdano and I discuss recent progress in automated scientific discovery of governing laws for complex networked systems, where neural symbolic regression can extract interpretable laws from high-dimensional dynamics. www.nature.com/articles/s43...

Discovering the laws behind complex networked systems - Nature Computational Science

A recent study shows that neural symbolic regression offers a route to automated discovery of governing equations for network dynamics across high-dimensional complex systems.

A follow-up article by NGN offers a window into the curiosity and inspiration behind Iacopo Iacopini’s food-focused research. news.northeastern.edu/2025/11/12/w...

Cuisines can be broken down into simple 'culinary fingerprints,' research finds

Network scientist Iacopo Iacopini looked to understand how different cuisines have congregated around certain core ingredients and flavors.

🗞️ The latest NGN features a discussion with I. kiss on our latest paper "Disentangling the Role of Heterogeneity and Hyperedge Overlap in Explosive Contagion on Higher-Order Networks" recently published in PRL [https://doi.org/10.1103/z3d5-94zb] news.northeastern.edu/2025/11/24/w...

Why do the latest fads spread like wildfire? Research explains

Network scientists found that the social overlap between groups plays a major part in how fast a phenomena or contagious illness transmits.

We found a nice way to accurately solve the SIS model. Rather than expanding in space with ever larger moment closures (pairs, triples, ...), we expand in time. No more difficult than pair-approximations yet much more accurate. arxiv.org/abs/2509.11706

The threshold and quasi-stationary distribution for the SIS model on networks

We study the Susceptible-Infectious-Susceptible (SIS) model on arbitrary networks. The well-established pair approximation treats neighboring pairs of nodes exactly while making a mean field approxima...
