Head-tail planaria morphologies are influenced by the electric potential differences across animal's primary axis, as evidenced e.g. voltage-sensitive dyes and functional experiments that create permanent lines of 2-headed but genetically wild-type animals. However, bioelectrical biochemical models make predictions on what would happen in case spatial chimeras made tissue transplantation from different (different species head shapes) lacking. Here, we use a model to qualitatively describe effects shape regenerated head. To this end, assume cells may have distinct sets ion channels ascribe system outcome axial distributions average cell potentials over morphologically relevant regions. Our rationale is signaling ions molecules spatially coupled with multicellular potentials. Thus, long-time downstream transcriptional events should be triggered short-time processes. We show relatively small between channel characteristics could eventually give noticeable changes profiles expected morphological deviations, which suggests timely actions significant effects. approach based observed relationships regionalization gradients body-plan studies.

Abstract A critical aspect of evolution is the layer developmental physiology that operates between genotype and anatomical phenotype. While much work has addressed mechanisms evolvability specific genetic architectures with emergent complexity, one not been sufficiently explored: implications morphogenetic problem-solving competencies for evolutionary process itself. The cells works are passive components: rather, they have numerous capabilities behavior because derive from ancestral unicellular organisms rich repertoires. In multicellular organisms, these must be tamed, can exploited, by process. Specifically, biological structures a multiscale competency architecture where cells, tissues, organs exhibit regulative plasticity—the ability to adjust perturbations such as external injury or internal modifications still accomplish adaptive tasks across metabolic, transcriptional, physiological, problem spaces. Here, I review examples illustrating how physiological circuits guiding cellular collective impart computational properties agential material serves substrate then explore ways in which intelligence during morphogenesis affect evolution, providing new perspective on search This key feature software life helps explain remarkable speed robustness sheds light relationship genomes functional phenotypes.

The ideas of self-observation and self-representation, the concomitant idea self-control, pervade both cognitive life sciences, arising in domains as diverse immunology robotics. Here, we ask a very general way whether, to what extent, these make sense. Using generic model physical interactions, prove theorem several corollaries that severely restrict applicable notions self-observation, self-control. We show, particular, adding observational, representational, or control capabilities meta-level component system cannot, even principle, lead complete representation whole. conclude self-representation can at best be heuristic, self models general, empirically tested by systems implement them.

Morphoceuticals are a new class of interventions that target the setpoints anatomical homeostasis for efficient, modular control growth and form. Here, we focus on subclass: electroceuticals, which specifically cellular bioelectrical interface. Cellular collectives in all tissues form networks via ion channels gap junctions process morphogenetic information, controlling gene expression allowing cell to adaptively dynamically pattern formation. Recent progress understanding this physiological system, including predictive computational models, suggests targeting interfaces can embryogenesis maintain shape against injury, senescence tumorigenesis. We propose roadmap drug discovery focused manipulating endogenous bioelectric signaling regenerative medicine, cancer suppression antiaging therapeutics.

Previous studies show that city metrics having to do with growth, productivity and overall energy consumption scale superlinearly, attributing this the social nature of cities. Superlinear scaling results in crises called 'singularities', where population demand tend infinity a finite amount time, which must be avoided by ever more frequent 'resets' or innovations postpone system's collapse. Here, we place emergence cities planetary civilizations context major evolutionary transitions. With perspective, hypothesize once civilization transitions into state can described as one virtually connected global city, it will face an 'asymptotic burnout', ultimate crisis singularity-interval time becomes smaller than innovation. If develops capability understand its own trajectory, have window affect fundamental change prioritize long-term homeostasis well-being over unyielding growth-a consciously induced trajectory 'homeostatic awakening'. We propose new resolution Fermi paradox: either collapse from burnout redirect themselves prioritizing homeostasis, cosmic expansion is no longer goal, making them difficult detect remotely.
