  • Visualizing dynamical changes in glassy systems is challenging because of the time and length scales involved. Now, atomic force microscopy is shown to be a viable method for obtaining a spatio-temporal description of the relaxation of a glass.

  • The transition from a glassy to a liquid phase is normally assumed to take place cooperatively across the whole material. But now, experiments show that, under certain conditions, isolated regions of liquid can form in the glassy matrix first.

  • Some ultrastable glasses films had been observed to lack the “universal” low-temperature anomalies of glasses, but the role of their anisotropy was unclear. In this article, by measuring the specific heat of an organic material in different glassy states at low temperatures, it is shown that the suppression of two-level systems in glasses depends on the degree of stability, not on anisotropy.
