Peer-Reviewed Publication

Loneliness and social isolation are linked to a range of serious health problems, but their overall toll on healthy life has been hard to quantify until now. In a first-of-its-kind study published in Nature Communications, Tulane University researchers analyzed data from 277,489 UK Biobank adults tracked for more than a decade. They found men experiencing both loneliness and social isolation lost up to six years free from depression and anxiety. Women, meanwhile, lost roughly four fewer years.

In House primaries, organized groups matter more than voters, new book finds

Annenberg Public Policy Center of the University of Pennsylvania
Book Announcement

With the vast majority of the 435 U.S. House seats considered safe for one party or the other, the primary is the election that usually determines who goes to Congress — and it is the election Americans know the least about. A new book finds that voters are rarely the most important influence on the outcome. "Parties on the Ground: A Study of Nominations for the House of Representatives" (University of Chicago Press, September 2026) finds that the organized groups anchoring each party’s coalition do the work of vetting candidates, coordinating behind them, and supplying the money and volunteers a nomination requires. Their goal, the authors find, is not ideological purity but reliable representation: a nominee who will faithfully represent their interests.
