# n-soc: what differentiates human from machine (at least for now)

<< Growth in the first industrial revolution was driven by engineering, the second through electricity and production lines, and the third by technology and information >>

<< As robots increasingly take on manual labor, we will need to foster what differentiates human from machine (at least for now): creativity >>

# gst: apropos of transitions, three distinct new families of long-wave instabilities and potential new pathways to turbulence.


AA << reveal three previously unknown instabilities, distinct from the well-known Kelvin-Helmholtz Instability (KHI) and Holmboe Wave Instability (HWI), in that they have longer wavelengths (..) and often slower growth rates. >>

<< The circumstances under which turbulence can persist in strongly stratified flows remains a fascinating debate within the community. [AA] demonstrated that weakly unstable (very) long waves may trigger turbulence and mixing after long periods of time, even under initially very strongly stratified conditions. >>

# life: apropos of transitions, a leap from chemistry to biology, the hypothesis of self-assembling droplets, the 'droplet world'.


AA << identify conditions suitable for concurrent peptide generation and self-assembly, and (..) show how a proliferating peptide-based droplet could be created by using synthesised amino acid thioesters as prebiotic monomers. Oligopeptides generated from the monomers spontaneously formed droplets through liquid–liquid phase separation in water. The droplets underwent a steady growth–division cycle by periodic addition of monomers through autocatalytic self-reproduction. Heterogeneous enrichment of RNA and lipids within droplets enabled RNA to protect the droplet from dissolution by lipids. >>

<< By constructing peptide droplets that proliferate with feeding on novel amino acid derivatives, we have experimentally elucidated the long-standing mystery of how prebiotic ancestors were able to proliferate and survive by selectively concentrating prebiotic chemicals, (..) Rather than an RNA world, we found that 'droplet world' may be a more accurate description, as our results suggest that droplets became evolvable molecular aggregates—one of which became our common ancestor. >> Muneyuki Matsuo.

# phyto: a molecular compass to coordinate growth

<< Using this protein [protein BASL: Breaking of Asymmetry in the Stomatal Lineage] to detect the polarity field is like switching a light on in each cell across the tissue. It allows us to see that these cells all have a compass, pointing in the same direction across the leaf >>

<< In this way we will find out if, as we suspect, this molecular compass is a conserved mechanism in the development of plant shapes across the plant kingdom which could be co-opted in different ways by different branches of evolution. >> Catherine Mansfield.

# s-brain: behaviour vs. gut e-coli: twenty minutes after

<< Twenty minutes after a meal, gut microbes produce proteins that can suppress food intake in animals >>

<<  (..) gut bacteria may help control when and how much we eat >>

<< The new evidence coexists with current models of appetite control, which involve hormones from the gut signalling to brain circuits when we're hungry or done eating. >>

# brain: immagini #CTZ, cicliche fantasmatiche pervasive visioni ricorrenti

<< Vladimir Putin has trumpeted the growth of national populist movements in Europe and America, crowing that liberalism is spent as an ideological force.

In an FT interview in the Kremlin on the eve of the G20 summit in Osaka, Japan, the Russian president said “the liberal idea” had “outlived its purpose” as the public turned against immigration, open borders and multiculturalism. >>

i giochi fisiologici che si giocano su questo pianeta (forse anche altrove) sono giochi 'aperti', all'interno dei due vincoli del gioco 'legale' (sostanzialmente i due vincoli del casino' [#1,#2]); al di fuori dei due vincoli non c'e' auto-struttura, auto-funzione, auto- manutenzione, e dove non c'e' auto- manutenzione la speranza di sopravvivenza - in funzione del tempo - di qualsivoglia sistema vivente cala, smorza, scema, declina; questa sembra la realta' funzionale di un sistema complesso dove le interne sub-unita' sono in continua interazione (non lineare); la propensione di entita' CTZ sensibili, specialmente quando costrette a fronteggiare bi/ multi- forcazioni, di ricondurre i punti di riferimento decisionali alle classiche, storiche, rituali  tre 'immagini'  (CTZ,  appunto) - il 'Campanile', la 'Terra', la 'Zappa' (da li' l'anagramma: 'ne Campa il ZappaTerra') - e' sostanzialmente illusoria perche' i tre punti di riferimento CTZ non permettono all'entita' transeunte di risolvere / reimpostare in modo soddisfacente i suoi problemi, veri o presunti tali; talvolta si ha l'illusione di una risoluzione, che sara' tuttavia irreversibilmente instabile rispetto al tempo; il Campanile e' una immagine che per sua intima natura e' relativa, le teoretiche che lo giustificano, lo sostengono, hanno contorni s-fumati, che scricchiolano (evaporano) dalle troppe contraddizioni interne; la Terra 'trema', anch'essa per sua intima natura, e' transitoria, si incendia, congela, sbricciola, frana, si allaga, viene spazzata periodicamente da vortici d'aria, e' sensibile a imponenti  forze esterne, cosmologiche, percio' partecipa attivamente alla  compromissione della stabilita' di qualsivoglia Campanile (Totem, Lampione ...); la Zappa e' per sua intima natura un oggetto 'techno', dipende dallo stato dell'arte tecno-scientifica, e attualmente e' in mutazione verso le graziose forme del 'robota', oggetto prospetticamente autonomo,  fisicamente, neuralmente (culturalmente?) ...

Il bravo (e fortunato) dr. Albert - Albert Hofmann, chimico con il pallino dell'azzardo sperimentale, un classico ... - aveva forse trovato il giusto approccio, la giusta 'medicina' per offrire 'respiro' anche a lungo termine alle moltitudini entita' CTZ-dipendenti (neuralmente, geneticamente dipendenti?), specialmente se e quando  coinvolte in contesti di accidentale modalita' accelerativa transeunte; e' davvero disdicevole che la molecola di Hofmann (LSD [#3]) presenti effetti collaterali non insignificanti; se gli effetti 'epigenetici' sono fisiologicamente troppo lenti per fronteggiare una realta' mutaforma dirompente e pervasiva, allora forse servirebbe una nuova 'magica stringa' [#4] farmacologica o di natura genetica, farmaco-epigenetica, allo scopo di alleviare almeno quegli stati confusionali, depressivi e i comportamenti a-priori lesivi- autolesivi tipici dell'entita' CTZ-dipendenti; anche e senz'altro per quell'altre entita', ben mimetizzate, a loro dire solo apparentemente illusoriamente insensibili a visioni / vincoli CTZ.

Davvero disdicevole accadimento (per i non pochi) lo storico 'salto' dallo 'standard' entita' nomade esploratrice erratica verso il qualcos'altro, ...  non e' vero?
