Information Dynamics in Urban Crime.
Universidad Distrital Francisco José de Caldas, and Pontifical Xaverian University, Bogota, Columbia scientists provide a novel systems analysis for this endemic scourge, particularly in their home country, and nations in both hemispheres. Our further interest is to recognize that by such studies, as long intimated, there exists a deeper, independent, mathematical fundament to our daily lives, which our chaotic personal and communal days and nights hold to and express. See also Netto, et al below, and Matjaz Perc elsewhere for similar views.
Information production in both space and time has been highlighted as a way to record the footprint of complexity in natural and socio-technical systems. However, its relation to urban crime has barely been studied. This work uses multifractal analysis to characterize the spatial information scaling in urban crime reports and nonlinear processing tools to study temporal behavior. Our results suggest that information scaling in urban crime exhibits dynamics that evolve in low-dimensional chaotic attractors, which can be observed in several spatio-temporal scales.

Cities, from Information to Interaction.
By way of the latest complexity sciences, seven urban and ecosystem theorists from Brazil, Germany, and Switzerland scope out via a tandem synthesis of relative knowledge and social pattern and process. See also Melgarejo and Obregon above for another version whence a full contribution of scientific reason might so palliate and advise.
From physics to the social sciences, information is now seen as a fundamental component of reality. However, a form of information seems underestimated, that which is encoded in the very environment we live in. This paper addresses three related problems if we are to understand the role of environmental information: (1) the physical problem: how can we preserve information in the built environment? (2) The semantic problem: how do we make this information meaningful? and (3) the pragmatic problem: how do we use it in our daily lives? We introduce a three-layered model of information in cities, namely environmental information in physical space, in semantic space, and the information enacted by interacting agents. Our results suggest that ordered spatial structures and diverse land use patterns encode information, and that aspects of physical and semantic information coordinate interaction systems.

Major Transitions in Planetary Evolution.
Ikegami, Takashi, et al, eds.
ALIFE 2018 Conference Proceedings.
Cambridge: MIT Press, 2018.
A select paper from this online volume by Arizona State University astrogeobiologists who perceive life’s oriented development as a nested iterative scale of relative informational genomes and aware organisms in communal groupings. A further worldwide emergence could be our linguistic personsphere sapience via a cumulative geonomic culture which is able to reconstruct all this.
Earth has undergone a succession of stages driven by physical, chemical, geological, biological, and social processes. Among the most significant transitions in Earth’s planetary

evolution are the emergence of life and subsequent biochemical innovations, social behavior and cognition, and of technology. After life emerged, planetary processes became much more complex due to diverse biogeochemical possibilities. With the advent of collective cognitive societies, many planetary processes became controlled by life. With higher technologies, intentional steering of the environment commenced. In each stage, new mechanisms of control, mediated by novel information processing architectures, are added to existing levels on the biosphere environment. We can classify these evolutionary stages of planets into matter-dominated, life-dominated, and agency-dominated phases, where each is distinguished by how much information processing systems might affect planetary processes.

In this paper we characterize physics, life, intelligence, and technology from each other in terms of the ole of information in controlling matter, and how this shapes the planetary environment, allowing the possibility of placing these phases on the same continuum. This suggest three phases of planetary evolution for comparison: matter-dominated (no life), life-dominated, and intelligence-dominated, where transitions between these correspond to
changes in the organization of information in physical systems, and how that organization constructs and controls the planetary environment. (101) Humanity’s ways of storing, sharing, and using information are transitioning Earth from a life-dominated planet to an agency-dominated planet. (102)

U.S. Climate Report Warns of Damaged Environment and Shrinking Economy.
New York Times.
A front page headline about a penultimate document entitled the Fourth National Climate Assessment which details brute evidence from hurricanes in Florida and fires in California to every erratic weather event in between that an epic unmitigated peril is occurring in our midst. This is Volume II, after a 2107 Climate Science Special Report, as a mandated culmination of the Global Change Research Act of 1990. The 1500 page report, which can be accessed from this article, stresses that much more damage will be done to any economy by the longer it is denied and ignored. This large document appears concurrently with another noted in the November 2018 Nature Climate Change article by Camila Mora, et al herein.

Broad Threat to Humanity from Cumulative Climate Hazards Intensified by Greenhouse Gas Emissions.
Nature Climate Change.
A 23 person team mainly from the University of Hawaii with others in Sweden, the UK, Japan and the USA summarize an immense study of historic deleterious impacts upon some 100 food, water, health, economy, infrastructure, security concerns. See also “Like a Terror Movie:” How Climate Change Will Cause More Simultaneous Disasters about this study by John Schwartz in the New York Times for November 19.
The ongoing emission of greenhouse gases (GHGs) is triggering changes in many climate hazards that can impact humanity. We found traceable evidence for 467 pathways by which human health, water, food, economy, infrastructure and security have been recently impacted by climate hazards such as warming, heatwaves, precipitation, drought, floods, fires, storms, sea-level rise and changes in natural land cover and ocean chemistry. By 2100, the world’s population will be exposed concurrently to the equivalent of the largest magnitude in one of these hazards if emissions are aggressively reduced, or three if they are not, with some tropical coastal areas facing up to six simultaneous hazards. These findings highlight the fact that GHG emissions pose a broad threat to humanity by intensifying multiple hazards to which humanity is vulnerable.

A Stochastic Approach to Shortcut Bridging in Programmable Matter.
We cite this by MA, University of Granada, Sarah Cannon, UC Berkeley, Joshua Daymode and Andrea Richa, ASU and Dana Randal, Georgia Tech as an example of the cosmic evolutionary epic entering a radically novel phase of total makeover, a second Alpha one might say, as our intentional, globally informed, respectful humankinder may begin a new ecosmos (re)creation.
In a self-organizing particle system, an abstraction of programmable matter, simple computational elements called particles with limited memory and communication self-organize to solve system-wide problems of movement, coordination, and configuration. In this paper, we consider a stochastic, distributed, local, asynchronous algorithm for “shortcut bridging”, in which particles self-assemble bridges over gaps that simultaneously balance minimizing the length and cost of the bridge. Army ants of the genus Eciton have been observed exhibiting a similar behavior in their foraging trails, dynamically adjusting their bridges to satisfy an efficiency trade-off using local interactions. Our work gives a plausible explanation of how convergence to globally optimal configurations can be achieved via local interactions by simple organisms with some limited computational power and access to random bits.

Living Machines: A Handbook of Research in Biomimetics and Biohybrid Systems.
Oxford: Oxford University Press,
With a Preface by Terence Sejnowski, the 600+ page volume achieves a conceptual and practical entry to this evolitionary transition (aka Genesis 2.0) via our palliative and beneficial furtherance of nature’s dynamic biologic creativity. A first section reviews how Life self-organizes, reproduces, metabolizes, uses energy, evolves and develops, by way of active organic materials. Attributes such as vision, touch, chemosensation, and strength, along with movement, learning, control, decision making, voice and pattern recognition and more are discussed throughout. Some entries are Self-Organization by Stuart Wilson, Growth by Barbara Mazzolini, A General Theory of Evolution by Terence Deacon, Capabilities by Paul Verschure, Consciousness by Anil Seth, and Ethics by Hannah Maslen and Julian Savulescu.
harness the principles discovered in nature and embody them in new artifacts, and biohybrid systems, which couple biological entities with synthetic ones. Living Machines surveys this flourishing area of research such as self-organization and co-operativity, biologically-inspired active materials, self-assembly and self-repair, learning, memory, control architectures and self-regulation, locomotion in air, on land or in water, perception, cognition, control, and communication. In all of these areas, the potential of biomimetics is shown through the construction of a wide range of devices and animal-like robots. Biohybrid systems is relatively new but is likely to shape the future of humanity.
