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.

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.

* 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:

If you are working with street/planar/spatial networks, this will solve *so* many problems! Many of my projects had this bottleneck - […]

The numbers are in. @bsky.app research sharing volumes vs X Formerly Twitter

In March 2024, on most days, Bluesky hosts more posts linked to research published in 2025 than X.

By quite a lot.

This was a fun experiment we conducted while developing The AI Scientist-v2. With the permission of ICLR, we submitted an AI-generated paper to an ICLR workshop that passed the peer-review process.

We documented the entire process and what we have learned in a blog post: sakana.ai/ai-scientist...

🎉 New paper in PNAS: Urban highways are barriers to social ties
https://www.pnas.org/doi/10.1073/pnas.2408937122

Highways are barriers that cut opportunities for social ties. We quantify this effect by overlaying the US highway network with millions of social ties from Twitter.

Can simple closed-form mathematical models predict human mobility as well as deep learning? In a new paper in
@naturecomms.bsky.social we show that the answer is YES

Human mobility is well described by closed-form gravity-like models learned automatically from data www.nature.com/articles/s41...

We're hiring a postdoc in the &-Lab at Northeastern's Network Science Institute!

Looking for a curious, collaborative scholar to work on computational social science questions, at the intersection of data justice + network science.

Have been using Cursor for writing LaTeX documents for a while. The idea was simple: Cursor is helpful for coding, and TeX is code in a way, so I gave it a try, and it worked perfectly.

It does require some configuration, so I'm sharing mine here: github.com/yang3kc/curs....
