WHERE THE RUBBER MEETS THE ROAD A new technique reveals microscopic details of the interface between two surfaces that are in contact. It uses high frequency sound or pulses of heat to probe the interface, which is inaccessible to conventional microscopes. The technique, reported in the December Physical Review B, could be a valuable tool for polymer scientists and biologists alike. Thomas Dehoux et al., Phys. Rev.
