🔊 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.

DOI: 10.1038/s41562-025-02282-7
There is a hidden simplicity behind how people move
DTU scientists show that once you account for geographical restraints, there are consistent patterns behind human mobility.

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.

"Urban Highways Are Barriers to Social Ties" out on PNAS!
The 1st large-scale measure of how highways weaken social connections between the communities they separate. This barrier effect is strong in the 50 largest US cities--especially for low-income Black communities.

Love this. In his “I Agree” installation Dima Yarovinsky-Yahel took the content from terms of service statements for companies like Facebook, Snapchat, Instagram, Tinder and printed them out on A4 paper with a standard font size for legal contracts to demonstrate the length of these agreements.

Today, the SFI Press published Vol. 4 of Foundational Papers in Complexity Science. This concluding book follows Volumes 1 & 2 in May and Volume 3 in September & contains papers published between 1989 and 2000 — when complex-systems science had become a fledgling field of study in its own right.

Thank you @natureportfolio.bsky.social for making my review of the Anxious Generation open access for parents, policy-makers, and the public. The story told in this book runs counter science and is leading to poor policy decisions that will ultimately fail our kids. www.nature.com/articles/d41...
The great rewiring: is social media really behind an epidemic of teenage mental illness?
The evidence is equivocal on whether screen time is to blame for rising levels of teen depression and anxiety — and rising hysteria could distract us from tackling the real causes.
