Il numero di oggi sembra uno speciale sulla nuova “civilt\u00e0 delle macchine” e un omaggio imprevisto a Marvin Minsky.<\/p>\n
Dall’editoriale “Digital Intuition”:<\/p>\n
computer scientists at Google DeepMind in London\u00a0unveil the successor to Deep Blue<\/a>. It is a program called AlphaGo, and in October 2015 it\u00a0beat the human Go champion of Europe<\/a>\u00a0by five games to zero. To put that into context, in Deep Blue\u2019s time, a human beginner with just a week\u2019s practice could easily defeat the best Go computer programs. A match between AlphaGo and the world\u2019s most titled player of the decade\u00a0is lined up for March<\/a>.<\/em> Oh dear.<\/p>\n Articolo <\/a><\/strong>di Elizabeth Gibney, reazione<\/a><\/strong> di alcuni campioni di go, il paper<\/a><\/strong>\u00a0di David Silver et al. e, ciliegina sulla torta, il racconto in ultima pagina \u00e8 intitolato “Robot Burial<\/a><\/strong>“. E i robot ci sono anche nel paper sulla batteria a litio <\/a><\/strong>che si auto-riscalda:<\/p>\n We expect the all-climate battery to enable engine stop\u2013start technology capable of saving 5\u201310 per cent of the fuel for 80 million new vehicles manufactured every year. Given that only a small fraction of the battery energy is used for self-heating, we envisage that the all-climate battery cell may also prove useful for plug-in electric vehicles, robotics and space exploration applications.<\/em><\/p>\n *<\/p>\n Algoritmi simili farebbero comodo in altri campi. Nella “Perpective”, Reto Knutti e altri amici di Steph\u00a0scrivono<\/a><\/strong> che un aumento di 2 \u00b0C della temperatura globale non rappresenta quello su scala regionale e i suoi impatti fisici e sociali. Fanno modelli-scenari per macro-regioni, per es. il Mediterraneo e ne elencano anche i cinque problemi (caveat) principali. Comunque<\/p>\n We focus here on regional changes because local stakeholders and decision-makers are more likely to be able to relate to them than to global mean temperature changes. However, we stress that this does not imply that countries should only be concerned about climate changes affecting them directly in a geographical sense. Indeed, because of globalization, major climate disruptions in some countries can strongly affect others, for instance owing to political unrest, migration, impacts on global food production, supply chains and trade.<\/em><\/p>\n *<\/p>\n Come ogni settimana o quasi, esce un miglioramento della tecnologia CRISPR-Cas9 per il “genome editing”. Finora modificava geni o inseriva la correzione anche dove non doveva, ma\u00a0Benjamin P. Kleinstivern<\/a><\/strong> et al. usano quella dello\u00a0Streptococcus pyogenes <\/i>che stando agli effetti “rilevabili” sembra arrivare solo sul bersaglio.<\/p>\n *<\/p>\n Shaoni Bhattacharya ha indagato<\/a>\u00a0<\/strong>sulla strage illegale degli uccelli migratori a Cipro:<\/p>\n It wasn’t until I saw the blade glinting in the sunlight that I realized how grave the situation was. Broad and belligerent in army fatigues, the man strode along the track, ranting in Greek. Behind his back, his hands flexed a knife blade in and out of its wooden handle. This man was a trapper, a poacher of birds \u2014 and he clearly didn’t want company. \u201cWhat are you doing here?\u201d he demanded.\u00a0<\/em> *<\/p>\n Nelle news, David Cyranovski<\/a> <\/strong>si chiede se i macachi geneticamente modificati da\u00a0Z.

\n… the new technology relies on a suite of deep neural networks. These were trained to mimic the moves of the best human players, to reward wins and, using a probability distribution, to limit the outcomes for any board position to a single verdict: win or lose. Working together, these machine-learning strategies can massively reduce the number of possible moves the program evaluates and chooses from \u2014 in a seemingly intuitive way. (…)<\/em>
\nWhen a conventional computer tells an engineer to place a rivet or a weld in a specific place on an aircraft wing, the engineer \u2014 if he or she wishes \u2014 can lift the machine\u2019s lid and examine the assumptions and calculations inside. That is why the rest of us are happy to fly. Intuitive machines will need more than trust: they will demand faith.<\/em><\/p>\n
\nMy companions and I had come to this dry scrubland on the Mediterranean island of Cyprus to look for evidence of songbird trapping. The birds are caught illegally and eaten in a traditional dish called\u00a0<\/em>ambelopoulia\u00a0\u2014 and I was joining a September trip to monitor the extent of trapping.<\/em><\/p>\n
\n Chianti, Toscana<\/a><\/strong>: una bambina di 6 anni che non pu\u00f2 essere vaccinata non pu\u00f2 nemmeno andare a scuola perch\u00e9 otto bambini su diciotto non sono vaccinati.

\nDal momento che\u00a0le misure vaccinali rappresentano l’unico strumento in grado di tutelare l’organismo di fronte alla possibile insorgenza di patologie virali e batteriche<\/strong>, il giovane (Cristiano Gianessi) ha dunque voluto lanciare il suo accorato appello pro-vaccini, ribaltando per un attimo i tradizionali luoghi comuni del Web, dove fa pi\u00f9 notizia un presunto caso di paziente danneggiato dalla misura di migliaia di veri malati che soffrono per l’assenza di coperture specifiche<\/em>.<\/p>\n
