It was a ton of fun to play a small role in this project lead by the brilliant Marta Ewa Lech & @jonassjuul.bsky.social. A lot of drama & change in the world of music reflected in the song-dynamics of the Billboard Hot 100!

New paper out in EPJ Data Science! We analyze 65 years of Billboard Hot 100 data to ask: 🎵Are songs moving differently up and down the chart nowadays? 📉 Are hits shorter-lived? 📈 Or do superstars dominate more than ever? Paper: epjdatascience.springeropen.com/articles/10.... 🧵 1/7

🎶 If you want to kiss the sky, better learn how to kneel On your knees, boy … She's the wave, she turns the tide She sees the man inside the child … It's all right, it's all right, it's all right She moves in mysterious ways 🎶 (Unless you normalize using the pair distribution function)

In this article, Boucherie et al. apply physics-based models to the arrangement of locations to study how geography shapes human movement. They find an underlying pattern in how people choose to move, independent of geographical layout.

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.

🔊 More from our recent @nathumbehav.nature.com article from the Technical University of Denmark: Our study shows that behind the apparent complexity of human mobility lies a simple rule shaped by geography and distance. 🔗 www.dtu.dk/english/news... DOI: 10.1038/s41562-025-02282-7

* Decoupling geographical constraints from human mobility * 🌍🚶 How much of our movement is about human choice and how much is constrained by geography and the spatial layout of locations? Our paper (out in Nature Human Behavior) gives you a practical way to tell: www.nature.com/articles/s41...

A pro-Russia content aggregation network is churning out at least 3 MILLION pieces of propaganda per year, all on sites that are virtually unusable by humans. So what's the goal? We explore the idea that it might be to flood LLMs with pro-Russia content: static1.squarespace.com/static/6612c... 1/

Visiting @mpidr.bsky.social this week—super excited to see what’s happening in Demographic Studies (don’t miss my talk!). Also, I’ll be in Berlin on Feb 2, Helsinki from Feb 3-6, and Copenhagen from Feb 10-12. Let me know if you’re around and up for a coffee 🧪🔬☕️

I disagree with perplexity.ai CEO Aravind Srinivas about the importance of sourcing in search results, but boy does he have Google's number here. Search for something they can't sell, you get an AI summary. Something they can, you don't. Try it yourself. From: www.fastcompany.com/91125423/per...

Dear academics We could dramatically reduce our administrative workload if we all just agreed not to ask for reference letters until we made our list of finalists. This is massive collective action problem has already been solved by… *checks notes* …every other industry on earth.

This is interesting. People are starting to do distributed training runs of big models. Still problematic in terms of energy use and overall safety (!), but it seems to mean that all the LLM action doesn't need to be concentrated within a few big companies. www.primeintellect.ai/blog/intelle...

One of the best pieces we published this year—a deep (and surprisingly moving) story about AI chatbots and the people who love them.

Great move! Foursquare just open-sourced their 100M+ place point of interest dataset. location.foursquare.com/resources/bl...

If you're looking for a postdoc, I cannot recommend Esteban's group highly enough. Esteban is awesome, the work is cool and innovative, & being at the Network Science Institute puts you near the center of the Network Science Universe.

I teach a network science class where students create a short video to present their final project. This one blew my mind and restored my faith in humanity! (I recommend watching with sound on!)
