When you say “science outreach,” most people think of working with K-12 students. Reaching adults is just as important, since adults decide how much our society values science, but this can be much more difficult. Even adults who bring their children to science fairs and care about STEM engagement can find it hard to relate to demonstrations and lessons designed for kids. Science by the Cup, an outreach initiative run by the Princeton Graduate Molecular Biology Outreach Program and supported by an ASBMB Outreach Seed Grant, is targeted specifically for adults to address this outreach gap.

One way that Science by the Cup differs from a science cafe, another event class typically aimed at adults, is that Science by the Cup events are not led by scientists. Rather, they are led by an expert with a specialized skill that requires knowledge of the underlying science. The first Science by the Cup event was a tour of Rojo’s Roastery, a small batch coffee maker in Princeton, NJ, that was led by its founder J. David Waldman. Mr. Waldman discussed the chemicals behind coffee’s flavor and aroma, as well as how coffee beans are harvested and processed. Graduate student volunteers complemented the tour by discussing how taste receptors function, the genetic basis of flavor, and subjectivity and bias.

The second Science by the Cup event was a tour of a brewery and a discussion of the biology of fermentation, leading to a discussion of the technology behind genetically modified yeast and other organisms and the ethics behind this work. Science by the Cup has been very successful and plans to continue holding events to showcase local experts and the science behind their skills.
