      abstract     = {The unique mechanical performance of animal cells and
                      tissues is attributed mostly to their internal biopolymer
                      meshworks. Its perplexing universality and robustness
                      against structural modifications by drugs and mutations is
                      an enigma in cell biology and provides formidable challenges
                      to materials science. Recent investigations could pinpoint
                      highly universal patterns in the soft glassy rheology and
                      nonlinear elasticity of cells and reconstituted networks.
                      Here, we report observations of a glass transition in
                      semidilute F-actin solutions, which could hold the key to a
                      unified explanation of these phenomena. Combining suitable
                      rheological protocols with high-precision dynamic light
                      scattering, we can establish a remarkable rheological
                      redundancy and trace it back to a highly universal
                      exponential stretching of the single-polymer relaxation
                      spectrum of a "glassy wormlike chain." By exploiting the
                      ensuing generalized time-temperature superposition
                      principle, the time domain accessible to microrheometry can
                      be extended by several orders of magnitude, thus opening
                      promising new metrological opportunities.},
