For people traveling, in the military, without access to water — or just too exhausted to get out of bed — skipping the toothbrush for a day is sometimes inevitable. Pitt undergrads Lauren Yocum and Emily Siegel's winning pitch for a biodegradable chewing gum that kills bacteria and removes and prevents plaque could bridge the gap.

Pitt senior Prachi Patel’s research project encourages refugee youth living in Pittsburgh to share their voices through photography. See the exhibit at Hillman Library through March.
