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?

# ecol epidem: deforestation vs. increase of infectious diseases, a new hypothesis

<< Habitat loss is associated with emerging infectious diseases.
Most hypotheses to explain this association focus on ecological drivers and community structure; however, none have been developed to consider coevolutionary selective pressures across a fragmented landscape.
The 'coevolution effect' proposes that, within habitat fragments, shifts in population structure among hosts, obligate parasites, and pathogens function in parallel and act as 'coevolutionary engines', accelerating pathogen diversification, and therefore increasing pathogen diversity across a degraded landscape. When combined with bridge vectors (e.g., mosquitoes and ticks) this increases the probability that pathogens with zoonotic potential may spill over into human communities. >>

# brain: 'moral emotions' as a hypotetical diagnostic tool for dementia

AA << shows a particularly marked impairment of moral emotions in patients with frontotemporal dementia  >>

<< Frontotemporal dementia is a cognitive and behavioral disease caused by degenerative alteration of anterior regions of the brain. The disease is characterized by behavioral disorders such as a progressive apathy, loss of interest, social withdrawal, loss of inhibition and the processing of emotions. >>

AA << have known for a long time that these patients demonstrate impairment of emotion recognition and of theory of mind i.e. the ability to figure out the mental states of others: what they think, what they feel, what they like ... >>

<< Moral emotions can be defined as  "affective experiences promoting cooperation and group cohesion" including emotions such as admiration, shame or pity. >>

<< The results show that moral emotions are much more impaired than emotions without moral valence. In contrast, patients with Alzheimer's disease had no impairment as compared to healthy subjects and they had similar performance with moral and extra-moral emotions. >>

<< A new program-writing AI, SketchAdapt, offers a way out. Trained on tens of thousands of program examples, SketchAdapt learns how to compose short, high-level programs, while letting a second set of algorithms find the right sub-programs to fill in the details. Unlike similar approaches for automated program-writing, SketchAdapt knows when to switch from statistical pattern-matching to a less efficient, but more versatile, symbolic reasoning mode to fill in the gaps. >>

<< Rather than rely on experts to define program structure, SketchAdapt figures it out using deep learning. The researchers also added a twist: When the neural networks are unsure of what code to place where, SketchAdapt is programmed to leave the spot blank for search algorithms to fill. >>

# gst: "diffusing wave paradox",  synthetic microswimmers can mimic the behavior of Amoeba

<< Amoeba are unusual creatures that form when a dispersed population of cells spontaneously comes together and reorganizes itself into a multicellular macroscopic organism. To do this, a few leader cells emit chemical pulses that cause the other individual cells to move in the direction opposite to that of the traveling pulses (the "diffusing wave paradox," ), leading to the formation of dense clusters. >>

<< In experiments, the researchers used spherical particles that are half-coated by a carbon cap and placed in a viscous liquid. When illuminated by light, the particles propel themselves forward with the cap in front. >>

<< At low pulse speeds, the particles have enough time to reorient themselves, if needed, so that their caps are facing in the same direction as that of the traveling pulses. This orientation ensures that the particles travel in the same direction as the pulses. >>

<< At high pulse speeds, on the other hand, the pulses come too quickly for the particles to reorient themselves before the next one comes. This is because the speed of the particles' rotation is limited by the friction of the viscous liquid. So if the particles' caps are initially facing the oncoming pulses, the particles will move counter to the direction of the traveling pulses, resembling the behavior of amoeba in the diffusing wave paradox. >>
