Mechanical structures are only as sound as the materials from which they are made. For decades researchers have studied materials from these structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that a structure may be weakening. While researchers have studied individual dislocations in the past, a team from the University of Illinois at Urbana-Champaign, the University of Tennessee, and Oak Ridge National Laboratory has made it possible to understand how dislocations organize and react at nanoscale.

A new 3D imaging technique is enabling scientists to view cells like never before without using dyes or even disturbing them. The method uses conventional microscopes and white light to create high-resolution, three-dimensional images of cells and their internal structures.
