From a spaghetti-like jumble of microfibers and water comes a promising new material

Tue, 05 Dec 2017 12:34:28 -0500

Princeton researchers are researching hydrogels that form through the shearing effect of fibers sliding against each other when forced through a syringe. This chemical-free method points toward a new class of injectable hydrogels that perform tasks such as plugging and treating wounds.

Frymer discusses 'Building an American Empire'

Wed, 29 Nov 2017 13:58:22 -0500

This fall, Princeton politics professor Paul Frymer’s latest book, “Building an American Empire: The Era of Territorial and Political Expansion,” was published by Princeton University Press. The book examines the politics of American expansion, showing how the federal government's land use policies — particularly those regulating the process of population settlement and removal — were critical to the nation's racial formation.

How global warming is drying up the North American monsoon

Wed, 11 Oct 2017 13:39:00 -0400

Previous researchers have concluded that global warming was simply delaying the North American monsoon, which brings summer rains to the southwestern U.S. and northwestern Mexico.  But a new, high-resolution climate model that corrects for persistent sea surface temperature (SST) biases now suggests that the monsoon is not simply delayed, but that the region's total rainfall is facing a dramatic reduction.
