# trade: positive effects of bubbles during innovations

AA << study is the first to look at the occurrence of bubbles in association with a large set of specific innovations introduced across two centuries, and to measure bubbles using statistical tests. [AA] are also the first to show that firms can benefit from bubbles driven by innovation. This is in contrast to the conventional thinking that that bubbles are detrimental that have few, if any, positive effects. >>

<< Using a sample of 51 major innovations introduced between 1825 and 2000, [AA] test for bubbles in the stock prices of parent firms subsequent to the commercialization of these innovations. [AA] identify bubbles in 73% of the cases. >>

# 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. >>

# trade: the immediate pump and dump in cryptocoin trading activities

<< Dozens of trading groups are manipulating the price of cryptocurrencies on some of the largest online exchanges, generating at least $825 million in trading activity over the past six months - and hundreds of millions in losses for those caught on the wrong side, according to a Wall Street Journal analysis. >>

<< In a review of trading data and online communications among traders between January and the end of July, the Journal identified 175 "pump and dump" schemes involving 121 different digital coins, which show a sudden rise in price and an equally sudden fall minutes later. >>

# gene: a single gene seems to confer reproductive status in ants (Ooceraea biroi).

<< a single gene is consistently up-regulated in queens. This gene seems to confer reproductive status through integration with increased nutrition. In a clonal ant, larval signals disrupt this gene up-regulation, destabilizing the division of reproductive labor. Increasing levels of the associated peptide override these larval signals and establish eusociality. >>

AA << findings suggest a simple model for the origin of ant eusociality via nutritionally determined reproductive asymmetries potentially amplified by larval signals. >>

# ai.bot: AI-BOT machine learning could become as a mystical Oracle of Delphi

<< In January this year, scientists did just that. They used machine learning to accurately predict the outcome of a chaotic system over a much longer duration than had been thought possible. And the machine did that just by observing the system’s dynamics, without any knowledge of the underlying equations. >>

<< Such AI oracles are already guiding self-driving cars and stock market investments, and will soon predict which drugs will be effective against a bacterium - and what the weather will look like two weeks ahead. They will make these predictions much better than we ever could have, and they will do it without recourse to our mathematical models and equations. >>

# game: pulsating as a Toffoli gate: Parrondo's paradox with a three-state coin (heads, tails, and a side)

<< Parrondo's paradox - an apparent paradox in which two losing strategies combine to make a winning strategy - can emerge as a coin game with a single coin in the quantum realm, but only when the coin has three states (heads, tails, and a side) rather than the conventional two. >>

<< In the new study, [AA] have demonstrated a Parrondo's game using a three-state coin, which they represent with a qutrit, a quantum system with three states. >>

quando lessi per la prima volta in bibliografia circa il "Parrondo Game"  mi venne in mente una strategia che avevo immaginato e piu' volte usato a suo tempo - da meta'  anni '70 a tutti gli anni '80 (e oltre) - composta da una sorta di "tit-for-tat stocastico" cioe' una strategia di gioco di  "cooperazione/ defezione" con decisioni di scelta pilotate da "lancio di moneta" all'interno di due (e poi anche tre) scenari riconducibili al tipo Parrondo ... in pratica la generazione di scenari senz'altro di  "frontiera", evolutivi,  immediatamente generabili all'interno di situazioni (se-si-puo-dire ... or, namely, "sire-die-soup") del tipo "standard", supposte "lineari".  Anzicheforse.
