Evolution of bow-tie architectures in biology
Tamar Friedlander, Avraham E. Mayo, Tsvi Tlusty +1
Bow-tie or hourglass structure is a common architectural feature found in biological and technological networks. A bow-tie in a multi-layered structure occurs when intermediate lay…
Anomalous Microfluidic Phonons Induced by the Interplay of Hydrodynamic Screening and Incompressibility
Tsevi Beatus, Roy Bar-Ziv, Tsvi Tlusty
We investigate the acoustic normal modes ("phonons") of a 1D microfluidic droplet crystal at the crossover between 2D flow and confined 1D plug flow. The unusual phonon spectra of…
Phonons in a one-dimensional microfluidic crystal
Tsevi Beatus, Tsvi Tlusty, Roy Bar-Ziv
The development of a general theoretical framework for describing the behaviour of a crystal driven far from equilibrium has proved difficult1. Microfluidic crystals, formed by the…
Pearling in cells: A clue to understanding cell shape
Roy Bar-Ziv, Tsvi Tlusty, Elisha Moses +2
Gradual disruption of the actin cytoskeleton induces a series of structural shape changes in cells leading to a transformation of cylindrical cell extensions into a periodic chain…
Molecular Model of the Contractile Ring
D. Biron, E. Alvarez-Lacalle, Tsvi Tlusty +1
We present a model for the actin contractile ring of adherent animal cells. The model suggests that the actin concentration within the ring and consequently the power that the ring…
High-Fidelity DNA Sensing by Protein Binding Fluctuations
Tsvi Tlusty, Roy Bar-Ziv, Albert Libchaber
One of the major functions of RecA protein in the cell is to bind single-stranded DNA exposed upon damage, thereby triggering the SOS repair response.We present fluorescence anisot…
