  • Analysis of the best available data on the behaviour of a large number of glass-forming organic liquids suggests that the widespread belief that a glass ceases to flow below its transition temperature could be wrong.

  • Scaling of the phonon damping with the wavevector in glasses is found to be different from the traditionally assumed Rayleigh scattering, and related to surprising, long-range correlations in the local elasticity matrix.

  • A simulation study of a model that mimics certain colloidal particles reveals a surprising low-temperature triumph of entropy, whereby the liquid state persists down to zero temperature.

  • A unified description of the dynamics of structurally disordered materials is challenging. Simulations of model systems now show that percolation theory provides a framework unifying the two most prominent relaxation processes in supercooled liquids and glasses.

  • Physical ageing in glassy materials can be described in a linear way through the concept of material time. Multispeckle dynamic light scattering is now shown to provide experimental access to the material time, in terms of which fluctuations become statistically reversible.

  • Researchers refer to the approximate invariance in the structure and dynamics of simple liquids among different pair models as quasi-universality, while little is known about its origin. Here, Becher et al.show that the pair potential as a sum of exponential terms fulfils the quasuniversality.

  • The temperature dependence of the viscosity of most glass-forming liquids is known to depart significantly from the classical Arrhenius behaviour of simple fluids. The discovery of an unexpected correlation between the extent of this departure and the Poisson ratio of the resulting glass could lead to new understanding of glass ageing and viscous liquid dynamics.

  • Melting is a classic first-order phase transition, but an accurate thermodynamic description is still lacking. Here, Pedersen et al. develop a theory, validated by simulations of the Lennard-Jones system, for the melting thermodynamics applicable to all systems characterized by hidden scale invariance.

  • Supercooled liquids near the glass transition show remarkable non-Arrhenius transport phenomena, whose origin is yet to be clarified. Here, the authors use GPU molecular dynamics simulations for various binary mixtures in the supercooled regime to show the validity of a quasiuniversal excess-entropy scaling relation for viscosity and diffusion.

  • The Prigogine–Defay ratio quantifies how many parameters are needed to fully characterize the glass-transition behaviour of a viscous liquid. For a single parameter, this ratio is unity, but it has never been clear whether any real liquid has such a value. A discovery of a connection between this ratio and the density scaling behaviour of silicone oil suggests it does.
