Trogu_Fig1“Giorgio Scarpa’s Model of a Sea Urchin Inspires New Instrumentation” by Pino Trogu
Giorgio Scarpa (1938–2012) was an Italian designer, artist and teacher who worked in bionics, topology and rotational geometry. This article describes Scarpa’s bionic model of “Aristotle’s lantern”—the mouth of the sea urchin. The technical literature on Echinoidea lacks a detailed study of its remarkable mouth mechanism. Scarpa’s model is the only known analysis and physical analogue of the mechanism. It is a striking example of geometrical analysis and craftsmanship, bridging science and art. Built in the early 1970s and described in 1985 in Modelli di Bionica, his model has inspired designs for a biopsy harvester and for a mini-rover to collect soil samples on Mars.

VIRTUAL MENAGERIES: ANIMALS AS MEDIATORS IN NETWORK CULTURES
BY JODY BERLAND

VirtualMenageries_coverIn Virtual Menageries, Jody Berland examines the role of animals in the spread of global communications. Her richly illustrated study links the contemporary proliferation of animals on social media to the collection of exotic animals in the formative years of transcontinental exploration and expansion. By tracing previously unseen parallels across the history of exotic and digital menageries, Berland shows how and why animals came to bridge peoples, territories and technologies in the expansion of colonial and capitalist cultures.
