Princeton recognizes advanced degree recipients in a time of ‘unprecedented challenges’ Denise Valenti, Office of Communications May 24, 2021 4:44 p.m. Princeton University’s graduate degree recipients and their mentors, family and friends gathered virtually on Monday, May 24, for the Graduate School’s 28th Hooding Ceremony. Many had also gathered in person on Sunday, May 16, for Princeton’s socially distanced Commencement, held for the first time at Princeton Stadium. Due to the COVID-19 pandemic, this was the second consecutive year in which the Hooding Ceremony was pre-...

‘See-Through Soil' Could Help Farmers Deal With Future Droughts In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers. Hydrogel beads, tiny plastic blobs that can absorb a thousand times their weight in water, seem ideally suited to serve as tiny underground reservoirs of water. In theory, as the soil dries, hydrogels release water to hydrate plants’ roots, thus alleviating droughts, conserving water and boosting crop yields...

Adam Hadhazy, Office of Engineering Communications Feb. 18, 2021 12:59 p.m. Princeton researchers used tiny glass beads as a substitute for soil, so they could observe the behavior of hydrogels — tiny plastic blobs that can absorb a thousand times their weight in water — whose success in agriculture has been puzzlingly uneven. The researchers used a chemical that compensated for the distortion caused by the round beads, resulting in a perfectly clear view of the hydrogel.
