Su Nature Climate Change<\/em><\/span><\/a>,<\/span> Manfred Lenzen dell’universit\u00e0 di Sidney et al. aggiungono un capitolo a\u00a0Travel & Tourism: Economic Impact 2017 <\/i><\/a>pubblicato dal\u00a0World Travel & Tourism Council:<\/p>\n

Here, we quantify tourism-related global carbon flows between 160 countries, and their carbon footprints under origin and destination accounting perspectives. We find that, between 2009 and 2013, tourism\u2019s global carbon footprint has increased from 3.9 to 4.5Gt CO2e, four times more than previously estimated<\/strong>, accounting for about 8% of global greenhouse gas emissions. Transport, shopping and food are significant contributors. The majority of this footprint is exerted by and in high-income countries.<\/p>\n

Grassetto mio. Commento di Sid Perkins,\u00a0Science<\/em><\/a>,<\/p>\n

The United Nations World Tourism Organization has previously suggested two ways to reduce the carbon footprint of global tourism: Travelers could choose destinations closer to home and use more public transportation, and governments could offer tourism providers incentives to boost their energy efficiency. To date, neither approach has been wildly successful, the researchers note.<\/p>\n

Due anni fa gli psicologi Matthew Hornsey, Emily Harris e Kelly Fielding dell’universit\u00e0 del Queensland, hanno chiesto on-line a 5323 persone di 25 paesi (Argentina, Australia, Brasile, Canada, Cile, Cina, Francia, Germania, Hong Kong, India, Indonesia, Irlanda, Giappone, Messico, Nuova Zelanda, Filippine, Polonia, Portogallo, Singapore, Sudafrica, Corea del Sud, Spagna, Svezia, UK e USA) se condividevano opinioni “complottiste” su una serie di eventi e come si situavano politicamente.<\/p>\n

we find that positive correlations between climate scepticism and indices of ideology were stronger and more consistent in the United States than in the other 24 nations tested.<\/p>\n

Davide Castelvecchi<\/span><\/a><\/span> spiega perch\u00e9 il CERN ha organizzato una competizione tra esperti di intelligenza artificiale. I dati diventeranno sempre di pi\u00f9, i computer faticano gi\u00e0 oggi a starci dietro, gli algoritmi del machine learning potrebbero accelerare non le particelle ma le tracce delle loro collisioni nei rilevatori del LHC:<\/p>\n

To help find the best solution, Jean-Roch Vlimant and other LHC physicists teamed up with computer scientists including Germain to launch\u00a0the TrackML challenge<\/a>. For the next three months, data scientists will be able to download 400 gigabytes of simulated particle-collision data \u2014 the pixels produced by an idealized detector \u2014 and train their algorithms to reconstruct the tracks.<\/p>\n

Participants will be evaluated on the accuracy with which they do this. The top three performers of this phase\u00a0hosted by Google-owned company Kaggle<\/a>, will receive cash prizes of US$12,000, $8,000 and $5,000. A second competition will then evaluate algorithms on the basis of speed as well as accuracy, Vlimant says.<\/p>\n

Nel caso gli algoritmi siano poco accurati<\/p>\n

Vlimant and other physicists are also beginning to consider more untested technologies, such as\u00a0neuromorphic computing<\/a>\u00a0and\u00a0quantum computing<\/a>. \u201cIt\u2019s not clear where we\u2019re going,\u201d says Vlimant, \u201cbut it looks like we have a good path.\u201d<\/p>\n

“Crappy”<\/strong>
\nAvete sentito dire che l’agopuntura\u00a0\u00e8 efficace e non ha effetti collaterali? Se vi viene il dubbio che sia bullshit, ne trovate la conferma da Real Clear Science<\/span><\/a><\/span>:<\/p>\n

\u00a0A new\u00a0meta-analysis<\/span><\/a><\/span>\u00a0published in\u00a0PLoS ONE<\/em>\u00a0comparing acupuncture and drugs for the treatment of chronic constipation is one of the worst studies I have ever seen.<\/p>\n

Secondo me lo studio peggiore rimane quello dei ricercatori del Dip. di Medicina all’universit\u00e0 di Bologna sullo sciroppo omeopatico della Boiron, cmq:<\/p>\n

Chinese researchers from Longhua District Central Hospital in Shanghai, China found that “acupuncture is more effective than drugs in improving chronic constipation and has the least side effects,” but they came to that conclusion by employing misleading tactics intended to produce that result.<\/p>\n

Le tattiche ingannevoli sono una mathturbation, per dirla con Tamino, un po’ ingenua.<\/p>\n

The vast majority of the laxative studies were double-blind, randomized, placebo-controlled trials published in peer reviewed journals.\u00a0\u00a0On the other hand, all of the acupuncture studies were unblinded, four were not peer-reviewed, five were published in questionable journals like the\u00a0Shanghai Journal of Acupuncture and Moxibustion<\/em>, and all were based in China, which is\u00a0notoriously friendly<\/a>\u00a0to acupuncture and alternative medicine.<\/p>\n

Gli studi sull’agopuntura non parlano quasi mai di effetti collaterali, in questo caso gli autori ne hanno trovato solo 1 su 12:<\/p>\n

They apparently neglected to read\u00a0numerous<\/a>\u00a0studies which\u00a0documented side effects<\/a>\u00a0like bleeding, bruising, or dizziness in roughly 7.4 percent\u00a0of cases<\/a>, as well as\u00a0rare, but serious events<\/a>\u00a0like traumatic lesions.<\/p>\n

Come di rito per le medicine alternative, scrivono che servirebbero studi “di qualit\u00e0” per confermare la maggiore efficacia e l’assenza di effetti collaterali dell’agopuntura,<\/p>\n

\u00a0but those studies will almost certainly never be done.\u00a0If they were,\u00a0the evidence would show that acupuncture doesn’t actually work<\/a>. The present study is a textbook example of what acupuncture proponents do to give their profession a veneer of scientific legitimacy: publish a crappy study in a journal with lax peer review.<\/p>\n

Steven Ross Pomeroy conclude:<\/p>\n

No doubt this shoddy, dishonest meta-analysis will be used to trick laypersons to seek acupuncture to cure their chronic constipation,\u00a0which is a growing problem<\/a>\u00a0in the United States and results in 700,000 trips to hospital emergency departments each year. By publishing this study, PLoS is complicit in promoting pseudoscience and leading people away from effective, evidence-based treatments for chronic constipation.<\/p>\n

Quando l’ha saputo, Steven Salzberg\u00a0si \u00e8 dimesso<\/span><\/a><\/span>\u00a0dal comitato di redazione di\u00a0PLoS One<\/em> che gli ha risposto<\/p>\n

Thank you very much for bringing these concerns to our attention. We are looking into this matter and will also be in touch with you separately to discuss further.<\/p>\n

Siccome PLoS One<\/em> ci ha messo ben\u00a0quattro anni<\/span><\/a><\/span> a ritrattare la\u00a0r\u00e9clame <\/span><\/a><\/span>di Oleg Epstein e al. della\u00a0Materia Medica Holdings<\/span><\/a><\/span>\u00a0per i propri prodotti omeopatici, Orac accelera la procedura con una post-peer review particolareggiata<\/span><\/a><\/span>.<\/p>\n

Maria Gloria Alcover Lillo, “un nome piuttosto noto”<\/strong>
\nDopo Germana Durando, l’omeopata hameriana condannata in prima istanza per l’omicidio di Marina Lallo, scrive Sofia Lincos <\/span><\/a><\/span>di Micromega,<\/p>\n

La procura di Torino\u00a0ha reso noto<\/a>\u00a0il nome di una nuova indagata per la morte di Marina Lallo: si tratta della dottoressa\u00a0Maria Gloria Alcover Lillo<\/a>, specializzata in omeopatia a indirizzo unicista, un nome piuttosto noto nel mondo delle medicine alternative. Il giudice per le indagini preliminari del Tribunale di Modena Stefano Vitelli, dove la donna risiede e lavora, ha anche disposto la sospensione dalla professione medica per la donna, considerata la \u201cmaestra\u201d della Durando, e per cui sussisterebbe la condizione di \u201ccolpa gravissima\u201d.<\/p>\n

Secondo quanto ricostruito dalle indagini anche lei avrebbe visitato Marina Lallo sconsigliandole di sottoporsi all\u2019intervento chirurgico. Agli atti, ad esempio, risulta una e-mail del 3 settembre 2014 in cui la dottoressa rimproverava la paziente per essersi sottoposta all\u2019asportazione del tumore e dava la colpa della produzione di metastasi a questa sua scelta \u201csconsiderata\u201d…<\/p>\n","protected":false},"excerpt":{"rendered":"
