\nMarco Micheli et al. del Centro di osservazione dei Near Earth Objects<\/a> fanno sapere che l’asteroide\u00a02016 WJ1 scoperto il 19 ottobre dal\u00a0Catalina Sky Survey<\/a>\u00a0non – ripeto non<\/strong> – colpir\u00e0 la Terra nel 2065 e neppure dopo.

L’accordo di Parigi sul clima \u00e8 spesso criticato perch\u00e9 confida troppo nella ricerca e lo sviluppo di tecniche per rimuovere CO2 dall’atmosfera, dette “carbon capture and storage” ed eventuale riutilizzo. Fra gli interventi di geoingegneria, mi sembra il pi\u00f9 sensato e non capisco perch\u00e9 escludere che si trovino sistemi adatti a varie scale – un po’ come succede per le celle e i pannelli solari. Su Andgewandte Chemie<\/em> per esempio, Charles Seipp et al. dell’Oak Ridge National Lab\u00a0descrivono<\/a>:<\/p>\n

\u00a0a simple aqueous guanidine sorbent that captures CO2\u00a0from ambient air and binds it as a crystalline carbonate salt by guanidinium hydrogen bonding.<\/p>\n

Poi basta scaldare un po’ i sali per recuperare da un lato la CO2 e dall’altro la guanidina che si pu\u00f2 riusare per altri due o tre cicli.<\/p>\n

Ce n’est qu’un d\u00e9but, dicono anche nel com. stampa<\/a>, anche perch\u00e9 stavano cercando di rimuovere inquinanti dall’acqua e hanno scoperto per caso che del carbonato si formava nella loro soluzione. Ora provano a migliorarla. Anche se Trump taglia i finanziamenti alle ricerche di Clean Energy, non importa: la\u00a0guanidina<\/a>\u00a0costa\u00a0poco.<\/p>\n

***<\/p>\n

Science<\/em> pubblica in open access <\/a><\/strong>il “policy forum” di Barack Obama sull’irreversibile sviluppo delle energie pulite.<\/p>\n

Since 2008, the United States has experienced the first sustained period of rapid GHG emissions reductions and simultaneous economic growth on record. Specifically, CO2 emissions from the energy sector fell by 9.5% from 2008 to 2015, while the economy grew by more than 10%. In this same period, the amount of energy consumed per dollar of real gross domestic product (GDP) fell by almost 11%, the amount of CO2 emitted per unit of energy consumed declined by 8%, and CO2 emitted per dollar of GDP declined by 18%. […]<\/p>\n

Of course, one of the great advantages of our system of government is that each president is able to chart his or her own policy course. And President-elect Donald Trump will have the opportunity to do so. The latest science and economics provide a helpful guide for what the future may bring, in many cases independent of near-term policy choices, when it comes to combatting climate change and transitioning to a clean-energy economy.<\/p>\n

“Non ci servono esperti”, cont.<\/strong><\/p>\n

Su Nature<\/em> di dopodomani,\u00a0Alberto Kornblihtt<\/a> descrive la collisione tra “scienza e nonsenso” che sta avvenendo in Argentina sotto il governo di Mauricio Macri:<\/p>\n

Macri is the son of a powerful industrialist and a former business partner of US president-elect Donald Trump in property development. The Panama papers, a huge cache of tax files leaked last April, showed that he (and his father and siblings) owned several offshore companies. He is bluntly applying the counter-Keynesian plan of opening the economy, reducing the role of the state, increasing foreign debt and creating unemployment to reduce the cost of wages. And\u00a0\u2014\u00a0despite his campaign promises to invest\u00a0\u2014\u00a0the latest national budget bill pushed by Macri and approved by the Congress for 2017 cut funds for science and technology by 30%.[…]<\/p>\n

Kornblihtt cita dichiarazioni ministeriali, del tipo gli scienziati non perdano tempo a pubblicare ricerca di base; si facciano delle start up per commercializzare applicazioni e se non hanno niente da vendere cambino lavoro.<\/p>\n

It gets worse […]<\/p>\n

To complete the landscape of nonsense, the chief of the cabinet of ministers, Marcos Pe\u00f1a, attacked one of the fundamentals of science by saying that \u201ccritical thinking has done too much damage to our country\u201d. He continued: \u201cSome people in Argentina think that being criticalis being smart. Our government believes that being smart is being enthusiastic and optimistic.\u201d<\/p>\n

This is gobbledygook, yet it neatly fits the New Age concept of the \u201crevolution of happiness\u201d proclaimed by Macri as a lubricant for social conflicts.<\/p>\n

Sar\u00e0 gobbledygook, ma ha fatto vincere le elezioni.<\/p>\n

Sulle orme di Condorcet<\/strong>
\nCombinazione, Guruprasad Madhavan, Charles Phelps e Rino Rappuoli – un ingegnere, un economista e un famoso biologo – sono insoddisfatti<\/a><\/strong> dei vari sistemi elettorali usati in democrazia. Raccontano un esperimento all’Institut Pasteur con un loro<\/p>\n

decision-support tool for public officials, corporate executives and donors to prioritize potential vaccines for research-and-development investment.\u00a0[…]<\/p>\n

Field-testing different selection methods in parallel with real voting situations should determine, for example, how often they produce different results and how much voters understand each approach, as well as what the potential consequences are. Such information can help groups to pick which rule would be best for them. Computer simulations could be used to analyse distributions of public preferences, and also situations in which conflicting voting problems actually occur.<\/p>\n

Certo, ma se gli elettori preferiscono promesse irrazionali (1) perch\u00e9 dovrebbero sforzarsi di capire ed eventualmente adottare un sistema basato su scelte e preferenze razionali?
