Long before railroads stitched continents together, mules and their Afro-Indigenous arrieros moved silver, sugar, cotton, and environmental knowledge across borders. In Distillations, @roguechieftan.bsky.social traces the mule as a tool of empire and a symbol of Black and Indigenous resistance. ⬇️

A 1700s book on color experiments reveals a vibrant magenta stain, likely from cochineal dye. Modern dyers confirm cochineal-alum makes a similar magenta. Read our latest Collections Blog post, as this stain tells the story of how New World ingredients transformed Old World dyes. ⬇️
Judith Kaplan's case study focuses on Science in American Life, an exhibit that opened in 1994 at the National Museum of American History.
As she notes, the exhibit's stakeholders (e.g., curators, donors, the public) had different goals--commemoration, historical educ., sci. literacy, etc. #HSS2025
Smith uses @sciencehistory.org's upcoming exhibit on fireworks (Flash! Bang! Boom!) to highlight many themes familiar to historians of science (e.g., links b/w military & civilian tech; advances in mat. sci & mfg., the creation of safety standards)
