# p-usa: #POTUS race: Donald presidency scares him to death, by Stephen

<< Author Stephen King spoke to Ron Charles, editor of The Washington Post's Book World, during a Facebook Live interview Saturday >>

<< If there's one man who would seem immune to fear, it's Stephen King, the best-selling author and master of horror fiction. But after more than 50 novels, hundreds of short stories and numerous film adaptations of his voluminous work, the 69-year-old still gets spooked >>

<< "A Tump presidency scares me more than anything else," King told Ron Charles [..] "I'm terrified that he'll become president" >>

<<  "I would have laughed three or four months ago, but I think that Trump has a real shot" >>

# s-behav: fertility, in a wide view of an open system

<< Male  peacock  spiders  know  how  to  work  their  angles  and  find  their  light. The  arachnids,  native  to  Australia,  raise  their  derriere  —  or,  more  accurately,  a  flap  on  their  hind end  — skyward  and  shake  it  to  attract  females. Hairlike  scales  cover  their  bodies  and produce  the vibrant  colorations that make peacock spiders so striking >>

# n-socsci-ai: a Study Panel to assess the current state of Artificial Intelligence

<< The One Hundred Year Study on Artificial Intelligence, launched in the fall of  2014, is a longterm investigation of  the field of Artificial Intelligence (AI) and its influences on people, their communities, and society. It considers the science, engineering, and deployment of  AI-enabled computing systems. As its core activity, the Standing Committee that oversees the One Hundred Year Study forms a Study Panel every five years to assess the current state of  AI. >>

# s-evol: pinnacle of nastiness, an example of natural flexibility

<< [..] venom genes might not be consistent even within a single species of rattlesnake, perhaps because snakes in different areas specialize in different prey. One western diamondback rattlesnake that Carroll’s team [Sean B. Carroll] sampled had unexpected extra genes that the other western diamondbacks didn’t have. >>

<< As for the ancestral rattlesnake, it’s impossible to say exactly how powerful the now-extinct reptile’s venom was, Carroll says. But the wider variety of enzymes this rattlesnake could hypothetically produce would have given it more flexibility to adapt its poison to environmental curveballs — an ability that Castoe [Todd Castoe] describes as “the pinnacle of nastiness.” >>

FonT: nella costellazione di "ricette" anti- invecchiamento la restrizione alimentare, intesa non come "dieta" ma come "stile di vita", e' l'approccio che nel corso degli ultimi decenni ha avuto (e ha tuttora nella letteratura scientifica internazionale) conferme sperimentali significative; uno stile che sa  associare (giornalmente) controllo alimentare bilanciato e attivita' fisica "dolce" (secondo una generica pratica zen, ad es.) sembra  l'approccio meno rischioso e il piu' efficace tra quelli proposti.

<< For millions of years the Australian jewel beetle's reproductive strategy proceeded very effectively. Then, Homo sapiens - and its habit of dumping used beer bottles - entered the picture. Unable to distinguish between these brown glass containers and the shell of a potential mate, the male beetles began attempting to copulate with discarded vessels. "They nearly went extinct" ... >>

# s-tech: a BZ skin for squishy bots

<< The potential to develop “materials that compute” has taken another leap (..) researchers for the first time have demonstrated that the material can be designed to recognize simple patterns. >>

<< This responsive, hybrid material, powered by its own chemical reactions, could one day be integrated into clothing and used to monitor the human body, or developed as a skin for “squishy” robots >>

<< The computations were modeled utilizing Belousov-Zhabotinsky (BZ) gels, a substance that oscillates in the absence of external stimuli, with an overlaying piezoelectric cantilever. >>

<< This (..) is an example of this groundbreaking shift away from traditional silicon CMOS-based digital computing to a non-von Neumann machine in a polymer substrate, with remarkable low power consumption. >>
