Polymer fibers extruded by microbes found in an abandoned Wisconsin iron mine serve as templates for the manufacture of microscopic crystals of hairlike proportions. The unusual crystals and how they are made may provide key insight into how nature makes some of its most durable materials, substances such as teeth, bone and shell. The work was reported in the March 12 issue of Science by a group led by Jill Banfield of UC-Berkeley and Gelsomina De Stasio, professor of physics at UW-Madison. Photo date: February 2004

Physics Professor Gelsomina "Pupa" DeStasio (R) can barely contain her excitement after analyzing new research data on her computers that suggests a break through in her research at the Synchrotron Radiation Center. DeStasio is joined here by her visiting Italian friend and colleague from the National Research Council Tiziana Parasassi (black) and graduate students Rachel Cannara and Brad Frazer (L).
