Chapel Hill, NC – Every scientist who works in a lab knows that labs have unique characters. The Isotope Geochemistry lab at UNC Chapel Hill was bustling with Ph.D. researchers, graduate students, undergraduate students, and researchers from other institutions, including Appalachian State University and The College of Wooster. We could tell it was a happy lab community by all of the happy faces. The faces weren’t just on the researchers; they were drawn on windows, hoods, and sticky notes. Here are few to brighten your day.
