Explore groundbreaking research on the 3D structure of pteropod shells in this 20-minute interview with Steve Weiner, professor emeritus at Weizmann Institute of Science. Discover how advanced imaging techniques revealed a unique microstructure in snail shells, challenging previous assumptions about their helical structure. Learn about the planar layer of nested S-shaped aragonite crystal fibers that form the basic repeating unit, and consider the implications of this discovery for materials science and the development of superior synthetic materials. Gain insights into the collaborative work led by Weiner and Lia Addadi's group, featuring PhD student Odelia Sibony-Nevo's contributions to this fascinating study published in MRS Bulletin.
