Theoretical explanation and a novel mechanism are given for the observation that viscosity of embryonic non-confluent tissue shows glass-like behavior till a critical cell density and saturates at higher densities.

Localized temperature gradients used as a novel method of active micro-theology that is non-invasive and probe-free, to investigate material responses of cell departments such as the different compartments of a nucleus displaying distinct material properties.

Radio frequency heating induced during magnetic resonance procedures within patients that carry embedded passive orthopedic implants may be accurately estimated through modeling and simulation.
Experimental manipulations and a mechanical model of the fiber reveal that the Reissner fiber is under heterogenous tension in vivo, and interacts with the motile cilia of diverse cells contacting the cerebrospinal fluid.
Habituation to mechanical vibration of crawling Drosophila larvae exhibits distinct time constants that characterize desensitization, re-sensitization, and further adaptation to repeated stimulus patterns.

Cell stretch release generates plasma membrane (PM) evaginations of ≈100 nm, triggering a local event of actin polymerization that flattens and recovers PM shape.
