Doctors at Leiden University hospital reenact Frank Lillie’s early placental dyeing method used as a diagnostic tool for assessing placental anastomosis. Used to study a biological phenomenon in genetically female cows born from a dizygotic twin pregnancy, called freemartinism, the dyeing technique maps the exchange of blood and hormones across the placental connection that renders the female twin intersex and unable to conceive.

Department

Artifacts, Action, Knowledge

Department Artifacts, Action, Knowledge studies the history of knowledge and action considering the interchangeable role of artifacts as texts, objects, and spaces. Collaborative working groups focus on project-based outputs that promote discussion and debate on the production of knowledge across all domains of life. Our research structure is organized around three key facets of knowledge: material artifacts, social action, and formalized epistemic expressions.
