This week on UnDisciplined, we're talking about biofuels ... and tattoos.
We're introducing an archaeologist and a chemical engineer, and if that doesn't already sound like a strange pairing, just consider what these guys study.
Andrew Gillreath-Brown is a doctoral candidate at Washington State University in Pullman, Washington. Writing in the Journal of Archaeological Science Reports, he and his colleagues recently announced the identification of a 2,000-year-old tattooing needle — one of the oldest such instruments ever discovered.
Swomitra "Bobby" Mohanty is an assistant professor of both chemical and metallurgical engineering at the Univeristy of Utah. He and his team recently described their super-fast method of turning algae into biocrude in the journal Chemical Engineering Science.
