🔊 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.

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.

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.
