Dynamical noisy canalization in morphogenesis: lessons from Hydra regeneration
Oded Agam, Erez Braun
Developmental robustness is framed as progress through a fixed Waddington-type landscape. We argue that in morphogenesis this landscape evolves through coupled bio-signaling, mecha…
Rupture-Repair Cycles in Regenerating Hydra Tissues
Oded Agam, Erez Braun
Destructive mechanical breakdowns and fractures are ubiquitous events in driven physical matter; living tissues, by contrast, can rupture repeatedly while restoring integrity. Here…
The Dual Nature of Body-Axis Formation in Hydra Regeneration: Polarity-Morphology Concurrency
Oded Agam, Erez Braun
The formation of a body-axis is central to animal development and involves both polarity and morphology. While polarity is traditionally associated with biochemical patterning, the…
Anomalous Thickness Dependence of the Vortex Pearl Length in Few-Layer NbSe2
Nofar Fridman, Tomer Daniel Feld, Avia Noah +16
The coexistence of multiple types of orders is a common thread in condensed matter physics and unconventional superconductors. The nature of superconducting orders may be unveiled…
Pattern formation in e. coli through negative chemotaxis: instability, condensation, and merging
Nir Livne, Ady Vaknin, Oded Agam
Motile bacteria can migrate along chemical gradients in a process known as chemotaxis. When exposed to uniform environmental stress, Escherichia coli cells coordinate their chemota…
