Functional Integration and Individuality in Prokaryotic Collective Organisations.
IAS-Research Centre for Life, Mind and Society, University of the Basque Country biotheorists GM, Leonardo Bich and Alvaro Moreno find evidence of a vital relative selfhood even in this primal realm. One could then notice that while bacteria subsist in collective groupings, they yet each retain a reciprocal degree and measure of personal, semi-autonomous identity.
Both physiological and evolutionary criteria of biological individuality are based on the idea that an individual is an integrated whole. However, a good account of functional integration has not been provided so far. To address this, we focus on the organization of two representative associations of prokaryotes: biofilms and the endosymbiosis between prokaryotes. This paper has three aims: first, to analyse the organisational conditions and the physiological mechanisms that enable integration in prokaryotic associations; second, to discuss the differences between biofilms and prokaryotic endosymbiosis and the types of integration they achieve; finally, to provide a more precise account of functional integration based on these case studies. (Abstract excerpt)
wumanomics > Integral Persons > Cerebral Form
In sum, functional integration can be defined as the degree to which the different components of a biological dynamic regime of self maintenance depend on one another for their production, maintenance, activity and reproduction. If we take the eukaryotic cell as the example of new forms of full fledged biological individuality by way of association between prokaryotes, individuality can be understood by the degree, scale and precision of the control and coordination of the parts that collectively make the system a viable functional whole. A cohesive integration between functional tasks is achieved, then, when the differentiation of functions is coordinated at the system level by control and regulatory mechanisms that (1) act across the entities in the association, and (2) are exerted in such a way that the components can contribute through their activity to the maintenance of the system.

Dynamic Representations in Networked Neural Systems.
Akin to Muhua Zheng, et al below, University of Pennsylvania neuroscientists delve deeper into our cerebral endowment to find more consistent, layered repositories of knowing inputs and response. Each paper cites dozens of prior references as our collective, 21st project of retrospective self-quantification proceeds to reveal a macro-uniVerse to micro-wumanVerse familial correspondence.
Recent studies in neuroscience have begun to independently address the two components of information processing: the representation of stimuli in neural activity and the transmission of information in networks that model neural interactions. Yet only recently are studies seeking to link these approaches. Here we review the two separate bodies of literature; we next note progress made to join them. We then discuss how patterns of activity evolve from one representation to another, forming dynamic content that unfolds on the underlying network. Our goal is to offer a holistic framework for understanding and describing neural information representation and transmission along with exciting frontiers for future research. (Abstract excerpt)

Spirituality, Dimensional Autism, and Schizotypal Traits.
Simon Fraser University and University of Alberta behavioral biologists consider Crespi’s research model (search) that generic autistic and psychotic states can be seen to represent diametric psychological poles of incoherent, unrelated pieces or overdrawn whole images. In this paper, such persuasions can also be seen to influence a person’s belief or lack thereof about any abiding, numinous meaning.
The relationships of spirituality with human social cognition, as exemplified in autism spectrum and schizophrenia spectrum cognitive variation, remain largely unstudied. We quantified non-clinical levels of autism spectrum and schizotypal spectrum traits and dimensions of spirituality in a large sample of undergraduate students. We tested the hypothesis, based on the diametrical model of autism and psychosis, that autism should be negatively associated, and schizotypal traits should be positively associated, with spirituality. First, in support of the diametric model, total Spirituality score was negatively correlated with Autism Quotient score, and positively correlated with Positive Schizotypal traits, as predicted. Second, these associations were driven by opposite patterns regarding the Search for Meaning Spirituality subscale. Third, Belief in God was correlated with Positive Schizotypal traits, but uncorrelated with autism traits. The opposite findings for Search for Meaning can be interpreted by cognitive models for understanding autism in terms of weak central coherence, and Positive Schizotypal traits in terms of enhanced salience.

Varieties of the Extended Self.
Consciousness and Cognition.
A La Trobe University, Melbourne philosophical psychologist considers how novel conceptions of one’s personal identity as widely spreading to and involved in web informative and group societal domains might imply an expanded sense of personal identity. In regard, the paper reviews a latest array of integrative and contrasting approaches and opinions.
This article provides an overview and analysis of recent work on the extended self whose boundaries fluidly shift across biological, artifactual, and sociocultural phases. We first offer a sense of a minimal self, person, and narrative self and then look at how philosophers, psychologists, and cognitive scientists see embodiment, cognition, emotion, consciousness, and moral character traits as extended. The main focus is on the link between the extended mind and extended self, which has received the most attention in recent literature. This article thus draws out some conceptual, methodological, and normative implications of the extended self and suggests directions for future research. (Abstract excerpt)

Multiple Metastable Network States in Urban Traffic.
Proceedings of the National Academy of Sciences.
After two decades of 21st century complexity studies, system theorists from China, the USA and Israel including Eugene Stanley and Shlomo Havlin are able to quantify a common nonlinear dynamics in formative effect even in the seeming chaos of city vehicular congestion. In regard, such exemplary evidence over a widest natural and social span now well implies the deep presence of an independent, universal mathematic source code.
While abrupt regime shifts between metastable states occur in natural systems from areas including ecology, biology, and climate, evidence for this vehicle transportation has rarely been observed. This absence might be due to a lack of methods to identify and analyze multiple states at scales of the entire traffic network. Here, using percolation approaches, we observe such a metastable regime in traffic systems. Based on high-res GPS datasets of urban traffic in Beijing and Shanghai, we find the existence of tipping points in three separate regimes: a global functional phase, a metastable hysteresis-like regime, and a global collapsed state. Our findings provide a better understanding of traffic resilience patterns and, potentially, other complex systems. (Abstract excerpt)

A History of Cosmic Habitability.
Journal of Big History.
This paper presented by the University of Rome Tor Vergata astrophysicist at the Life in the Universe: Big History, SETI and the Future conference in Milan in July 2019 provides a widest scientific retrospective scan of our resultant human worldwide presence. And by a philosophical view, one might wonder about what kind of overall scenario is being revealed to us. Whom are we regnant, curious, valiant peoples to be able to learn this, and for what reason and purpose?
Our understanding of the universe is based on the big bang cosmological model, which describes an expanding universe whose development began 13.8 billion years ago from a hot, dense state. This model introduces a strong evolutionary and historical perspective to the account of many observed physical phenomena, including the origin of life and its possible distribution in the universe. I discuss how properly taking the “big picture” and its temporal unfolding into account is relevant for the scope of astrobiology and SETi. (Abstract)
wumanomics > Phenomenon > Macrohistory
The fact that we live in an expanding universe with a finite age whose average state changed dramatically over time introduces a historical perspective to many of the physical processes that science tries to explain. I have argued that the problem of the origin of life, on Earth and elsewhere, must fully embrace this historical and evolutionary point of view. Investigating the history of cosmic habitability—i.e., of the propensity of the universe to host life—can illuminate many aspects of contemporary research in both astrobiology and

The 21st Century Singularity and Global Futures: A Big History Perspective.
As the summary next says, here are collected essays within a World-Systems Evolution and Global Futures series with a Russian cosmist philosophy (search) context. Their general message is a need for an expansive Earthwide spatial vista, set not only within a historic train but all the way back to cosmic evolutionary origins. By many aspects such as information, mobility, gene sequence, industry, and cities, a consummate, imminent moment for our rarest, cognizant planet then becomes evident. While notice of Ray Kurzweil’s tech takeover (search) is made, a broader, epochal transformation is well sketched. With regard to this resource site, a second ecosmic singular event of universal import does seem in imminent occurrence as Earth life’s emergence reaches its spherical superorganic spherical transformation.
Typical chapters are Singularity of Evolution and Post-singular Development in the Big History Perspective by Alexander Panov, The Twenty-First Century’s Mysterious Singularity” in the Light of Big History by Akop Nazaretyan, Big History as a Roadmap for the Future by Elise Bohan, and Global Brain: A Distributed Singularity by Cadell Last (search).

Future > Old World > anthropocene
This book introduces a 'Big History' perspective to understand the acceleration of social, technological and economic trends towards a near-term singularity, marking a radical turning point in the evolution of our planet. It traces the emergence of innovation rates through global history and highlights transformations throughout the evolution of life, humans, and civilization. The chapters survey historical mega-trends with regard to technology, population, energy, and information, models that can help understand mechanisms, future scenarios, along with paths and decisions that are required, philosophical perspectives on the meanings and implications of trends towards singularity, and finally the Search for Extraterrestrial Intelligence.

Multifractal Structure of the Monthly Rainfall Regime in Catalonia: Evaluation of the Non-linear Complexity.
The rain in Spain stays mainly in the plain was famously sung in My Fair Lady (1956). In 2020 Polytechnic University of Catalonia physicists proceed to quantify predictable patterns by way of advanced topological and computational methods.
The complex non-linear regime of the monthly rainfall in Catalonia is analyzed by means of the reconstruction fractal theorem and the multifractal detrended fluctuation analysis algorithm. Areas with a notable degree of complex physical mechanisms are detected by using the concepts of persistence (Hurst exponent), complexity (embedding dimension), predictive uncertainty (Lyapunov exponents), loss of memory of the mechanism (Kolmogorov), and the set of multifractal parameters (spectral asymmetry, width, and complexity). Besides these analyses permitting a detailed description of monthly rainfall pattern characteristics, the obtained results should also be relevant for new research studies concerning monthly amounts forecasting at a monthly scale.

Introduction to the Special Issue on the Statistical Mechanics of Climate.
Journal of Statistical Physics.
As another instance of the 2020 confirmation of complex dynamic systems in effect at every phenomenal phase, the University of Reading mathematician (search) introduces 24 papers such as Nonequilibrium Oscillations, Probability Angular Momentum and the Climate System, Extreme Sensitivity and Climate Tipping Points, and Phase Transitions and Extreme Events which contribute highly technical studies of local and global weather. And I log this in as hurricane Isaias with embedded tornados passes over my western Massachusetts, a very rare climate change result.
We introduce the special issue on the Statistical Mechanics of Climate by presenting an informal discussion of some theoretical aspects of climate dynamics that make it a topic of great interest for mathematicians and theoretical physicists. In particular, we briefly discuss its nonequilibrium and multiscale properties, the relationship between natural climate variability and climate change, the different regimes of climate response to perturbations, and critical transitions.

Does New Physics Lurk Inside Living Matter?
After his 2019 award-winning book The Demon in the Machine, the Arizona State University veteran natural philosopher once more alludes to “deep universal principles” that are implied as the presence of self-organizing informational, algorithmic programs at work becomes increasingly evident. See also Formal Definitions of Unbounded Evolution and Innovation Reveal Universal Mechanisms for Open-Ended Evolution in Dynamical Systems by Alyssa Adams, et al in Nature Scientific Reports (7/997, 2017) from Davies’ collegial group at ASU and beyond. In some participatory way we peoples who altogether can learn such theories might well be the universe’s way of intentionally continuing its co-pro-creative genesis.

Exploring Chemical Compound Space with Quantum-based Machine Learning.
Nature Reviews Chemistry.
We cite this entry by University of Basel, Berlin and Luxembourg material scientists as an example, largely unawares so far, of humankinder abilities to take over and begin a new physical, elemental and in/organic chemical co-pro-creation.
Rational design of compounds with specific properties requires understanding and fast evaluation of molecular properties throughout the huge set of all potentially stable molecules. Recent melds of quantum-mechanical calculations with machine learning show promise for exploring wide swathes of chemical compound space. We propose that significant progress in the understanding of chemical reactivity can be made through a systematic combination of physical theories, comprehensive data sets of microscopic and macroscopic properties, and modern machine-learning methods.

Towards Computer-aided Design of Cellular Structure.
Center for Cellular Construction researchers (see below) in league with UC Berkeley and UC San Francisco biophysicists including Wallace Marshall scope out this frontier 2020s phase when collective human intellect can begin a new, second, palliative, respectful genesis procreation.
Cells are complex machines with salutary potential for applications in medicine and biotechnology. Although much effort has been devoted to engineering the metabolic, genetic, and signaling pathways of cells, methods for systematically engineering the physical structure of cells are less developed. Here we consider how coarse-grained models for cellular geometry at the organelle level can be used to build computer-aided design (CAD) tools for cellular structure. (Abstract excerpt)
Future > New Earth > second genesis
Welcome to the Center for Cellular Construction, an NSF Science and Technology Center. Our mission is to advance cell biology by learning how to engineer the physical structure and interactions of living cells, so they become living bioreactors and modules of novel self-organizing devices. Accomplishing these goals will provide a new basis for tackling important global challenges of the 21st century.

Controlling Matter at the Molecular Scale with DNA Circuits.
Annual Review of Biomedical Engineering.
Johns Hopkins University biophysicists continue to advance (search) their studies of the many, seemingly unlimited, structural, computational and electronic capabilities of nucleotide biomolecules much beyond their genetic role. In regard, might these innate propensities imply a deep natural fertility which we cocreative peoples are meant to learn, avail to take forth anew?
In recent years, diverse mechanisms have been developed that allow DNA strands to sense information inputs so to control material assembly, disassembly, and reconfiguration. These sequences could serve as the inputs and outputs for DNA computing circuits which can act as chemical processors to program complex material behaviors. There are interfaces that can release strands of DNA in response to chemical signals, wavelengths of light, pH, or electrical signals, as well as direct the self-assembly and dynamic reconfiguration of nanostructures, and manipulate DNA crystals, hydrogels, and vesicles. These interfaces can enable chemical circuits to exert algorithmic control over responsive materials so they can grow, heal, and interact with their environments. (Abstract)
