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…
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…
Fluctuation-Driven Morphological Patterning: A Novel Approach to Morphogenesis
Oded Agam, Erez Braun
Recent experimental investigations into Hydra regeneration revealed a remarkable phenomenon: the morphological transformation of a tissue fragment from the incipient spherical conf…
