Network Medicine is entering a new phase: one that demands we rethink how we study, model and ultimately treat complex diseases.

✍️ ¡Nuevo artículo! Issa Luna Pla, @jrncarlock.bsky.social y Harald_Waxecker muestran por qué las redes criminales deben investigarse como sistemas, no como casos aislados. Enfrentarlas exige análisis de relaciones y acciones contra actores centrales.

How “intelligent” is a slime mold? When it solves mazes, it might not be thinking:it’s obeying physics. Our new paper with
@jordiplam.bsky.social shows how it follows a least action principle,letting physics do the job arxiv.org/pdf/2511.08531

The Bak-Sneppen model: species in a circle, each with random fitness. Replace the weakest species (and its neighbors) with new random values. Cascading evolutionary avalanches emerge, showing self-organized criticality from simple rules.

What is the physical basis of death? Can we manipulate cellular rules to avoid it? What does death mean for a machine? Is immortality possible? What does it mean for language, thought, or information to die? My new book @princetonupress.bsky.social is coming soon. press.princeton.edu/books/hardco...

In complex systems, linear tools fail against nonlinear phenomena. You can’t fight smoke with a sword, nor bite water with your teeth—because complexity dissolves brute force. It demands sensitivity, adaptability, and systemic understanding. #complexity

Super excited about our new paper on mobility that's out in Nature Human Behavior www.nature.com/articles/s41...

I love this paper for many reasons, but one is that we find beautiful 1/x power-law that spans 6 orders of magnitude hidden within the "ugly" distribution raw mobility data.

What is emergence? This is one of the most central ingredients of complexity, and a challenging one to formalize. Here's a paper by @seanmcarroll.bsky.social & Achyth Parola that attempts to classify different forms of emergence. @manlius.bsky.social @sfiscience.bsky.social arxiv.org/pdf/2410.15468

What is complexity? Complex Systems made of many interacting units display "emergence", i.e. global properties that cannot be reduced to the properties of the units. A new idea? WM Wheeler was one of the advocates of emergence, back in 1927 @sfiscience.bsky.social

Complexity, as a inherent quality of reality (interconnectedness), is a reminder that nature and knowledge go beyond our disciplinary labels. Science works according to disciplines, but reality just doesn't care (paraphrasing Feynman). #complexity #epistemology
