I tre sermoni in apertura di Nature<\/em> oggi meritano riflessione (e qualche dissenso):
\n– Universities challenged<\/a> <\/strong>riassume l’inserto “The University Experiment<\/a>” che comprende un articolo – impensabile soltanto dieci anni fa – sulla riforma delle universit\u00e0 cinesi;<\/p>\n

Ultimately, there are two possible universities of the future. There is the theoretical one: the institution devised in the abstract by selecting the most-innovative technologies and most-appealing ideas and packaging them together. This is the future of flying cars and Mars colonies. It may come to pass, but it is hard to see how. Then there is the university of the future that remains firmly rooted in the university of the present and the past; a place where students, teachers and scholars gather to share and seek information, and where both the information and the process that uncovers it have value.<\/em><\/p>\n

– Dust to Dust<\/a> <\/strong>riguarda le tracce di onde gravitazionali trovate dall’esperimento BICEP2, e il lancio mediatico della presunta scoperta:<\/p>\n

science not by press conference but presented as an event. What in reality is a long, messy and convoluted process of three steps forward and two steps back is too easily presented as giant leaps between states of confusion and blinding revelation. At the heart of this theatre is the artificial landmark of a peer-reviewed paper. Fixed print schedules and releases to journalists under embargo (with or without champagne videos) help to lend the impression that the publication of a paper is the final word on a question \u2014 the end-of-term report on a scientific project that details all that was achieved.<\/em><\/p>\n

Se ne discute da domani<\/a> al convegno annuale del Council for the Advancement of Science Writing.<\/p>\n

– Migliorare la peer-review ricompensando i peer-reviewers (competenti) \u00e8 il tema del terzo editoriale<\/a><\/strong> nel quale intravvedo solo io una coda<\/a> di paglia<\/a>?<\/p>\n

– Erwann Michel-Kerjan \u00e8 un economista specializzato in gestione del rischio alla Penn State e visto il nome che pi\u00f9 bretone di cos\u00ec … avrei un bias favorevole. Per\u00f2 a proposito di come rendere la “nostra economia a prova di terrorismo”\u00a0scrive_<\/a><\/strong><\/p>\n

Thirteen years later (l’11\/9 ndt) \u00a0terrorism risk insurance remains a peculiar, yet crucial, business. Governments want their citizens and corporations to have financial protection. But, for security reasons, they are reluctant to share information about a terror threat that is dynamic in nature: terrorist organizations morph and adapt to governments\u2019 foreign policies and countermeasures. Yet to decide on a cost-sharing agreement, and to make sure that compensation will be in place, all involved in the negotiations must have some idea of the probable impact of a possible terrorist act.<\/em><\/p>\n

Crede davvero che i governi arrivino a “condividere” quelle informazioni o che semmai lo far\u00e0 un Edward Snowden? E che creeranno una cassa comune per un rischio difficile da quantificare? Quando non sono in grado di farlo per i cambiamenti climatici o per quello quantificato in\u00a0Ebola by numbers<\/a><\/em>?<\/p>\n

Citazione:<\/p>\n

\u00a0Within the epicentre, authorities have made some progress in slowing transmission \u2014 but the disease is resurgent in places where it had seemed under control, such as in Conakry, Guinea\u2019s capital. Meanwhile, the estimated cost of fighting the disease is spiralling upward. UN secretary-general Ban Ki-moon warned on 9 October that \u201cat least a 20-fold surge in assistance\u201d was needed to confront the outbreak. But \u201cthings will get worse before they get better”, he warned. Just how much worse will depend on the international community \u2014 which has been widely criticized for its belated response, a<\/em>nd its slow translation of pledges into concrete action.<\/em><\/p>\n

Tradotto: 20 volte i $2 miliardi che arrivano a rilento. Quanti ne servivano in marzo per limitare l’epidemia a un quartiere di Conakry?<\/p>\n

David Heymann (“un’autorit\u00e0<\/a>“) spera ancora<\/a> che si traggano lezioni dalle strategie servite a\u00a0circoscrivere la prima epidemia di Ebola nel 1976, quando se ne era occupato da inviato dei CDC di Atlanta.\u00a0<\/span><\/p>\n

Oltre a quello sull’evoluzione genetica che consente alle farfalle monarca di migrare dal Messico al Canada e ritorno (che fisico, che muscoli alari!), \u00a0c’\u00e8 un\u00a0bel paper <\/a><\/strong>di Tomasz Kazimierczuk et al<\/em>. in\u00a0fisica sperimentale dei semi-conduttori e dei laser: hanno misurato eccitoni eccitatissimi con atomi giganti di Rydberg (un elettrone + un “buco”) in un cristallo di ossido di rame senza farci i buchi prima. Bozza gratis<\/a>:<\/strong><\/p>\n

We are convinced that the observation of these giant excitons opens a new field in condensed matter spectroscopy.<\/em><\/p>\n

Hanno anche altre idee, il finale \u00e8 un programma di ricerca in varie scienze. Adesso Giancarlo De Marchis mi smentisce e dice che \u00e8 un lavoro banale. Forse, mica leggo le riviste specializzate, comunque sono proprio contenta che ci siano riusciti fisici di universit\u00e0 “minori”.<\/p>\n

\nIl rame mi ha fatto pensare al TPR2 e di palo in frasca, o meglio di Ascoli65<\/a> in Nasturzio<\/a>, sono approdata anch’io all’esilarante report <\/a>di Daniele Poponi, del Sistema di informazione per la sicurezza della Repubblica,<\/p>\n

l\u2019insieme degli organi e delle autorit\u00e0 che, nel nostro Paese, hanno il compito di assicurare le attivit\u00e0 informative allo scopo di salvaguardare la Repubblica dai pericoli e <\/em>alle minacce provenienti sia dall\u2019interno sia dall\u2019esterno.<\/em><\/p>\n

sugli “Strategic Impacts of Breakthrough Energy Technologies” dette BET, nelle quali include le<\/p>\n

low-energy nuclear reactions (LENR), or nuclear technologies that have already been subject to some research (thorium-based fission or muon-catalized fusion).<\/em><\/p>\n

Fin qui ochei, anche se la fusione muonica per ora consuma pi\u00f9 energia di quanta ne produca.<\/p>\n

As far as LENR are concerned, such processes and related technologies have already been under the\u00a0scrutiny of intelligence organizations. An unclassified report prepared for the US Defense \u00a0Intelligence Agency (DIA) \u201cassesses with great confidence that if LENR can produce nuclear origin energy at room temperatures, this disruptive technology could revolutionize energy production and storage, since nuclear reactions release millions of times more energy per unit mass than do any <\/em>known chemical fuel\u201d.<\/em>
\nThe DIA analysts further highlight that \u201cthe potential applications of this phenomenon, if commercialized, are unlimited. LENR could serve as a power source for batteries that could last for decades, providing power for electricity, sensors, military operations and other applications in remote areas, including space\u201d.<\/em><\/p>\n
