  • The relaxation dynamics of granular materials is more like that of complex fluids than that of thermal glass-forming systems, owing to the absence of the ‘cage effect’.

  • Colloidal suspensions are used as the model systems to study the gelation dynamics because colloidal particles are large and thermal. Here, Li et al.show an alternative system, wet granular packing, whose local structures exhibit fivefold symmetries similar to those observed in colloidal gels.

  • Glass transition shows dramatic dynamic slowdown, but its origin remains unclear. Here, Xia et al. observe in granular systems the rapid growth of a geometrically frustrated polytetrahedral order with packing fraction, which is spatially correlated with the slow dynamics.

  • It is a general consensus that the structural defects are the plasticity carriers in amorphous solids, but its microscopic view remains largely unknown. Cao et a. show that highly distorted coplanar tetrahedra act as defects in granular packings, which flip under shear to carry local plasticity.
