Thanks @sfiscience.bsky.social for an accessible coverage of our paper!
Through modeling the growth process and empirically estimating key parameters, we find that while systems differ in how they add new functions, once a function is introduced, its growth follows a common sublinear preferential attachment process.
New paper in PNAS: We find Heaps' law, empirical regularity first identified in how diversity of vocabulary scales in books, also describes function diversity in cells and many human organizations (with cities being a notable exception). w/ @sfiscience.bsky.social www.pnas.org/doi/10.1073/...

Between 1985--2023, MIT's faculty grew 9%. Administrative staff grew 189%. 📈 Why? In new @pnas.org paper, we use dynamical system model to show administrative bloat can emerge without empire-building--just from well-intentioned problem-solving gone awry

Mastering a skill can take decades, but learning unfolds across timescales from moments to days. A new paper by three former SFI postdocs presents a theoretical model of nested timescales of learning, offering a unified, multi-scale account of skill acquisition. www.santafe.edu/news-center/...
