"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.

TikTok and the likes transformed how we spend time on our phones. But do they increase mobile use, or just reshuffle what we already do?
We find that adopting TikTok increases total mobile usage and shortens breaks from the phone.
