# life; a hypothetical externalization of knowledge effects; humans are thought to have decreased in brain volume since the end of the last ice age (3,000 y.ago)

<< Human brain size nearly quadrupled in the six million years since Homo last shared a common ancestor with chimpanzees, but human brains are thought to have decreased in volume since the end of the last Ice Age. The timing and reason for this decrease is enigmatic. Here (AA) use change-point analysis to estimate the timing of changes in the rate of hominin brain evolution. (They) find that hominin brains experienced positive rate changes at 2.1 and 1.5 million years ago, coincident with the early evolution of Homo and technological innovations evident in the archeological record. But (AA) also find that human brain size reduction was surprisingly recent, occurring in the last 3,000 years. >>

# s-phys: the beryllium anomaly, hypothesis of a fifth force

<< Earlier this year, an experiment in Hungary reported very unusual behavior in the decays of beryllium-8 nuclei. The experimental collaboration suggested that their results may come from the effects of a new force of nature. If confirmed, this would have far-reaching consequences on fundamental physics including grand unification, dark matter and the experimental strategy for pushing the frontier of human knowledge. >>

# brain: understanding of zero even among honey bees

AA << trained individual honey bees to the numerical concepts of "greater than" or "less than" using stimuli containing one to six elemental features. Bees could subsequently extrapolate the concept of less than to order zero numerosity at the lower end of the numerical continuum. Bees demonstrated an understanding that parallels animals such as the African grey parrot, nonhuman primates, and even preschool children. >>

could save in short-term, perhaps, the world from this big trouble (i.e.  'grande impiccio').

Here there are three simple questions: 

(a) Why in anticipation of the 'great tea trolley disaster' (after SARS appearance in Nov 2002, Guangdong, China; after MERS in Nov 2012, Gedda, Saudi Arabia) spray forms of antiviral drugs (e.g. remdesivir,  remdesivir like) have not been prepared?

e.g.  https://pubmed.ncbi.nlm.nih.gov/?term=antiviral+drugs+sars-cov-2

(b) Why in the meantime, hitech reusable anti-viral anti-bacterial fabrics not been studied and tested?

(c) Does it seem serious to propose a vaccine - to treat every six/eight months eight billion people inside a window of 15/30 days - to confine (sic) a mutant virus (one mutation every week) that is transmitted by air?

# age: cryobiosis; long-term nematodes survival (30-40k y.) from late pleistocenic permafrost (P. aff. detritophagus - Rhabditida - and P. aff. parvus - Plectida).

AA << have obtained the first data demonstrating the capability of multicellular organisms for longterm cryobiosis in permafrost deposits of the Arctic. The viable soil nematodes Panagrolaimus aff. detritophagus (Rhabditida) and Plectus aff. parvus (Plectida) were isolated from the samples of Pleistocene permafrost deposits of the Kolyma River Lowland. The duration of natural cryopreservation of the nematodes corresponds to the age of the deposits, 30 000-40 000 years. >>

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?
