    Reconstituted cytoskeleton networks linked with catch bonds display increased mechanical strength and crack resistance than those containing slip bonds, and simultaneously being more deformable, which allows for better adaptability to new mechanical environments.

    The liquid nature of hard glasses is demonstrated by broadband stress relaxation experiments. The rheology and dynamic transition of various glass systems can be unified by a universal scaling law in the time–stress–temperature–volume domain.

    The progressive stiffening of the solid–solid contacts that freeze dense colloidal suspensions are shown to cause the macroscopic ageing of such materials.

    Dense suspensions of hard particles readily display discontinuous shear thickening under shear but not reversible shear jamming. Here it is shown that the formation of interparticle hydrogen bonds is crucial for the shear jamming of these suspensions.

    Aggregations of fire ants are viscoelastic with identical elastic and viscous moduli, and exhibit shear-thinning behaviour when deformed beyond the linear regime.

    The cytoplasm of living cells responds to deformation in much the same way as a water-filled sponge does. This behaviour, although intuitive, is connected to long-standing and unsolved fundamental questions in cell mechanics.

    It has been suggested that the cytoplasm of living cells can be described as a porous elastic meshwork bathed in an interstitial fluid. Microindentation tests now show that intracellular water redistribution plays a fundamental role in cellular rheology and that at physiologically relevant timescales cellular responses to mechanical stresses are consistent with such a poroelastic model.

    Toothpaste, mayonnaise and other systems are soft particle glasses. In these, the soft particles are jammed so that the glasses behave like weak solids at rest but at sufficient stress flow like liquids. This has made their theoretical understanding difficult. A new micromechanical model is now able to predict the rheology of these soft particle glasses.

    In most suspensions viscosity decreases with increasing shear rate. The opposite effect, shear thickening, is a problem for industrial applications. An understanding of how particle interactions in suspensions influence shear thickening may lead to a solution of this problem through the design of smart suspensions.

    Experiments have shown that the physical characteristics of the matrix surrounding a stem cell can affect its behaviour. This picture gets further complicated by studies of stem cells and their differentiated counterparts that show that the cells' own softness also has a clear role in how they respond to stress.
