Per i 50 anni dello Science Citation Index inventato da John Garfield, e proprio mentre gli scienziati ne contestano usi e abusi, Nature<\/em> ha chiesto a Thomson – Reuters, che ormai ne \u00e8 proprietario, quali sono i 100 papers pi\u00f9 citati dal 1900 a oggi. Dei primi venti, ho letto solo quello di Sanger, Nicklen e Coulson<\/a>…<\/p>\n

The exercise revealed some surprises, not least that it takes a staggering 12,119 citations to rank in the top 100 \u2014 and that many of the world\u2019s most famous papers do not make the cut. A few that do, such as the first observation\u00a0of carbon nanotubes (number\u00a036) are indeed classic discoveries. But the vast majority describe experimental methods or software that have become essential in their fields.<\/em>
\nThe most cited work in history, for example, is a 1951 paper describing an assay to determine the amount of protein in a solution. It has now gathered more than 305,000 citations \u2014 a recognition that always puzzled its lead author, the late US biochemist Oliver Lowry. \u201cAlthough I really know it is not a great paper?\u2026?I secretly get a kick out of the response,\u201d he wrote in 1977.<\/em><\/p>\n

Tecniche e strumenti di lavoro sono pi\u00f9 citati dei grandi classici. D’altronde se si parla di relativit\u00e0 generale o di doppia elica del Dna, la nota bibliografica \u00e8 superflua.<\/p>\n

Editoriale<\/a><\/strong> su Ebola, che ripete “Time for Action”, ma<\/a><\/strong>… Tim Inglis<\/a> <\/strong>riassume le reazioni nei paesi ricchi, Australia in particolare:<\/p>\n

The Ebola outbreak has pitted rational science against fear and superstition. We see this in Africa: the murder last month of eight people working to raise awareness of the disease close to the town of Nzerekore, in southeastern Guinea, is a tragic example. But we see it in the supposed scientific superpowers too.<\/em>
\nIn the United States, for example, the debate over how the nation should respond is being undermined by media hype and political panic over domestic cases; there are calls for total bans on flights from the outbreak region. And here in Australia, the government is reluctant to send people to help to control the spread of the disease until it can get guarantees from nations closer to the outbreak that those people would be able to receive treatment in the event that they became infected. Worse, health-care workers who voluntarily went to the affected region to help have been criticized on their return to Australia. These people \u2014 including a nurse who developed a fever after her return (but tested negative for Ebola) \u2014 have been turned on by politicians and the press for putting fellow Australians at risk, despite having followed expert guidance and quarantined themselves.<\/em><\/p>\n

Erika C. Hayden<\/a><\/strong> racconta la protesta<\/a><\/strong> di medici e ricercatori contro<\/p>\n

the state of Louisiana’s decision to effectively ban doctors and researchers who have recently returned from Ebola-affected areas from attending a major meeting in New Orleans.\u00a0On 29 October, Louisiana officials told organizers of the annual meeting of the American Society of Tropical Medicine and Hygiene that recent returnees from the three West African nations most affected by the Ebola epidemic would be asked not to attend the meeting, which is to be held in New Orleans from 2 to 6 November. (…)<\/em>
\nMotivo, prevenire un rischio di cui la ministra locale per la sanit\u00e0 e quello per la sicurezza sanno che non esiste:
\n\u201c<\/b>From a medical perspective, asymptomatic individuals are not at risk of exposing others; however, the State is committed to preventing any unnecessary exposure of Ebola to the general public,\u201d Kleibert and Davis write in their letter to meeting organizers.<\/em><\/p>\n

L’ASTMH ha tolto il programma <\/a>dal suo sito, ma si pu\u00f2 ricostruirlo partendo dai nomi dei partecipanti previsti<\/a>\u00a0o per tema. Nel frattempo \u00e8 uscito l’aggiornamento <\/a>dell’OMS (mancano 5 giorni di dati per la Liberia): 13.703 casi, 4.922 vittime.
\nIn Liberia, sta rallentando<\/a><\/strong> la diffusione o rallentano i ricoveri<\/a><\/strong>?<\/p>\n

Vien da disperare anche leggendo l’<\/span>articolo<\/a><\/strong> di Erika H. sui ricercatori che anni fa avevano avvisato che un’epidemia di queste proporzioni era molto probabile, e sulle “domande” poste da Ebola e dai filovirus in generale, alle quali ancora non ci sono risposte. <\/span><\/p>\n

Per esempio, quale meccanismo immunitario protegge i sopravvissuti (la pi\u00f9 difficile, si sta ancora cercando di capirlo per l’HIV…)? Quante e quali sono le specie\u00a0 “serbatoio”? Qual \u00e8 il tasso di mutazione dei ceppi di Ebola attuali? \u00a0Ci lavora il gruppo di Pardis Sabeti, che dorme sulle brande e fa i turni 8×4 cos\u00ec le macchinette della PCR son sempre in funzione – ma per ora i dati sono “ambigui”.<\/span><\/p>\n

Simone Russo et al.<\/em> del JRC, ISPRA, CNR ecc. hanno pubblicato<\/a> sul\u00a0JGR-Atmospheres<\/em> una nuova scala per le ondate di calore, lo\u00a0Heat Wave Magnitude Index,\u00a0un po’ come per i terremoti<\/p>\n

in order to classify the strongest heat waves that occurred worldwide during the three study periods 1980-1990, 1991-2001 and 2002-2012.<\/em><\/p>\n

Per ora ha l’indice pi\u00f9 alto quella russa dell’estate 2010. Per il futuro,<\/p>\n

model predictions reveal an increase in the probability of occurrence of extreme and very extreme heat waves in the coming years: in particular, by the end of this century, under the most severe IPCC AR5 scenario, events of the same severity as that in Russia in the summer of 2010 will become the norm and are projected to occur as often as every two years for regions such as southern Europe, North America, South America, Africa and Indonesia.<\/em><\/p>\n
