# s-behav: individuality among Amazon mollies

<< Genetically identical Amazon mollies raised individually and under identical environmental conditions, nevertheless develop different personality types. Additionally, increasing the opportunity for social interactions early in life appears to have no influence of the magnitude of personality variation. >>

AA << team used the Amazon molly, a livebearing Poecilid species. These animals are natural clones, meaning all the offspring of one mother have exactly the same genetic material. >>

# s-brain: all rely on one central function: emulation

<< Our brain's fronto-parietal network is responsible for a range of highly diverse functions, from planning and executing movements to mental rotation, and from spatial attention to working memory. But how can a single network participate in such a wide variety of functions? >>

[AA]  << have recently put forward an original hypothesis — all these cognitive functions rely on one central function: emulation. This function creates an abstract dynamic 'image' of movements, thereby enabling the brain to strengthen its motor skills and construct a precise and lasting representation of them. >>

Acting and thinking — are they the same for our brain?

# e-ai: an intriguing hypothesis: cheating that system will become near impossible

<< Blockchain is an online global  database that anyone with an  internet connection can use  anywhere in the world. Unlike  traditional databases that are  owned by central figures like  banks and governments a  blockchain doesn’t belong to  anyone. And with an entire  network looking after it, cheating  the system by faking documents, transactions and other  information will become near  impossible. >>

# e-web: a space-based quantum internet, the begin

<< a team of physicists reports that it sent eerily intertwined quantum particles from a satellite to ground stations separated by 1200 kilometers, smashing the previous world record >>

<< Entanglement involves putting objects in the peculiar limbo of quantum superposition, in which an object's quantum properties occupy multiple states at once: like Schrödinger's cat, dead and alive at the same time. Then those quantum states are shared among multiple objects. Physicists have entangled particles such as electrons and photons, as well as larger objects such as superconducting electric circuits >>

# n-soc: inside a demonetized world, every(?)thing cheap or free, by Peter ...

<< At Singularity University's Exponential Finance Summit in New York [..], Diamandis [Peter Diamandis] talked about the broad and specific trends he believes are leading to a demonetized world >>

<< The counterbalance to technological unemployment [..] is the demonetization of living — in other words, pretty much everything we need and do in our day-to-day lives is becoming radically cheaper, if not free, and technology's making it happen >>

# s-phys: beyond the Standard Model, a hypothesis

<< A fundamental assumption of the Standard Model is that the interactions of these elementary particles [ leptons: electrons, muons and taus ] are the same despite their different masses and lifetimes >>

<< A new review of results from three experiments points to the strong possibility that lepton universality — and perhaps ultimately the Standard Model itself — may have to be revised >>

<< The rates for some decays involving the heavy lepton tau, relative to those involving the light leptons — electrons or muons — were higher than the Standard Model predictions >>
