Naomi Chayen and John Helliwell describe how recent advances in protein crystallography are providing new insights into their structure and properties. The curious phenomenon of sonoluminescence has puzzled theorists and experimentalists alike. Seth Putterman explains how the rapid pulsations of a gas-filled bubble can transform sound into light. Soft lithography and microfabrication Researchers at Harvard University have devised a new set of techniques that extend the capabilities of traditional lithography.
Soft lithography allows complex nanoscale structures to be formed, even on curved surfaces.
