Our article on the #mechanics of "active" entropic biopolymer networks [possibly including #actomyosin, this is debated experimentally] is now published in J Elas.
Compared to enthalpic models, we're able to go right from the #thermodynamics of an unbiased #molecularMotor activity (in the spirit of the model by #JacquesProst for #myosin) at the molecular scale to a network-scale model in a closed form.
And we derive a method for solving quite easily the (usually tough) #viscoelastic #liquid model that we obtain, using #deformationGradientDecomposition.

I’m getting preoccupied by the parallels between the design theorist Christopher Alexander’s metaphysics of form and Margaret’s Archer morphogenetic approach. The best critique of Archer I’ve read is Mouzelis arguing that she systematically prioritises time over space, leading her to neglect the spatialised exercise over power. I’m increasingly wondering if Alexander’s (somewhat power-blind, it seems to me) architectural theory of morphogenesis as a spatialised process, could be integrated into Archer’s morphogenetic approach.
From Christopher Alexander’s The Process of Creating Life, pg 509:
Why is freedom associated with the morphogenetic character of social processes? Because it is the shape-creating, organization-generating, aspect of process which ultimately allows people to do what they want, what they desire, what they need, and what is deeply adapted to life as it is lived and to experience as it is felt. The humanity of the environment comes about only when the processes are morphogenetic, are whole-seeking, are placed in a context that gradually allows people to work towards a living whole in which each person plays a part. If this point is not clear from what you have read in this book, please read Book 1, chapter 10, to understand more fully what I mean.
I believe we may take on this task, collectively, and can gain effective, instrumental knowledge of our generative system, and thus some measure of awareness and control over the system of processes that generates the world. I choose to define society as that system which creates the human world, and say that its primary ongoing function, and the criterion we should use to judge it by, is its capacity to create and re-create a living world for us.

Sir, ma'am, do you have a minute to talk about #evolution?
In these gloomy days, teaching #evolution is the safe harbour. Tomorrow the lecture is online, because I (and many students) are going to a strike in #Utrecht against budget cuts to higher education 🟥 , but I hope they will still enjoy these absolute classics:
Niklas, Karl J. "Evolutionary walks through a land plant morphospace." Journal of Experimental Botany 50.330 (1999): 39-52.
I still remember being awe-struck by the work of Karl Niklas on plant #biophysics and #morphogenesis when I was a 1st year student at the University of Warsaw. This was truly a portal to a world where everything in nature could be explained and had an underlying principle.
Budd, Graham E. "Morphospace." Current Biology 31.19 (2021): R1181-R1185.
While I am learning my part in French to explain #simulations of #evolution in Brussels for a Science is Wonderful show by @ERC_Research later this week.

This is a useful concept from Andrew Dryhurst in a recent paper in JCR. I’ve been prone to arguing for the same framing by talking about the need to historicise AI, in terms of a broader history of digitalisation then platformisation. I think Dryhurst’s framing here helps me account for how a particular framing of AI emerges both from failing to historicise it, as well as contributes to making it more difficult to do so in the future:
Traditionally, a large amount of philosophical functionalism has pervaded the AI space (Bryson Citation2019; Searle Citation1984), which has served to underpin an instrumentalist understanding of AI technology in much of the social science literature on the topic. Instrumentalism here refers to AI being understood as a tool and solely in terms of what it does. This is of course necessary at a certain level, given the wide-reaching scope of AI-use cases, the diversity of models and training sets, and the opacity that frequently surrounds AI’s societal deployment (O’Neil Citation2017). Nevertheless, instrumental notions of AI are inescapably presentist in their analytical scope, and it is important to consider that different AI are themselves embedded in an enormous variety of material relations and processes. AI are constructed and deployed by agents who are imbued with their own structural and institutional contexts, interests, ideals, and situational logics. A particular company’s AI systems are necessarily intertwined with the dynamics of (inter)national regulations, supply chains, and (national) accumulation regimes, as well as corporate agents’ reflexive and culturally conditioned actions in and through time. That is, AI are open complex systems embedded in other open complex systems.
https://www.tandfonline.com/doi/full/10.1080/14767430.2023.2279950#abstract
I think you can make this point without the CR vocabulary but it is a very important point which is very powerfully made here:
there is a research gap to be filled through tracing AI’s conceptual and material development in relation to the morphogenetically derived systemic imperatives traversing the political economy of the Internet and its history. For example, the ubiquitous deployment of AI models across all aspects of society presupposes questions about attribution concerning the datasets that are fed into different models; the transparency of data collection and processing; and the complex regulatory challenges that widescale AI deployment creates
And this is exactly what I’m interested in addressing, particularly the notion of models as cultural technologies, even if I arrived there through a slightly different route:
Similarly, the recursive and emergent consequences of people’s interactions with powerful AI models across industry and society make the models akin to cultural substrates from which particular worldviews may be inscribed and cultivated. To paraphrase Marshall McLuhan, the model may well be the message (Bratton and Agüera y Arcas Citation2022). All of these connote significant economic and social outcomes, and also exemplify a situation where the rise of powerful AI companies, possessive of their own intellectual property, datasets, and modelling practices, ought clearly to be situated within the accumulation imperatives and systemically persistent dynamics shaping the Internet’s development in capitalism because they are intertwined with and shaped by AI’s regulation and deployment as well.

Centuries ago, I published a manuscript on BioRχiv about the love/hate relationship between variability and robustness in embryogenesis.
And now, it's published in Science! I am so proud 🥳
https://www.science.org/doi/10.1126/science.adh1145
We went through three (3!) rounds of revisions. Although we did not change a comma in the abstract, the revisions improved the quality of the work very much (we nearly doubled the sample size and added an entire figure).
