Features
   
    In the past two decades, the picture of fusion plasmas has changed. Once analogous to an obscure work of abstract art, it is now more like a landscape full of comprehensible features -- Richard D. Hazeltine and Stewart C. Prager
   
    Lightweight yet stiff, metal foams are experiencing a resurgence of interest for applications ranging from automobiles to dental implants -- John Banhart and Denis Weaire
 
    The style of investigation exemplified by Goethe's experiments with color is often undervalued, but has repeatedly proved its worth -- Neil Ribe and Friedrich Steinle

Cover: Diagrams with gray and colored shapes on various backgrounds were among the objects Goethe studied in his investigations of color. The exploratory approach that Goethe and others followed has often proved valuable for science, especially when no overarching conceptual framework exists to guide experimentation. In their article on page 43, Neil Ribe and Friedrich Steinle discuss philosophical and historical aspects of this approach to research.
