The new generation of superconductors will allow the researchers from MIT and Commonwealth Fusion Systems (CFS) in Cambridge to strengthen the magnetic field that contains the hot-plasma fuel used in conventional\u00a0tokamak reactors<\/a>. That could pave the way for reactors that are smaller, cheaper and easier to build than those based on previous designs, including the\u00a0troubled international ITER project<\/a>\u00a0[…]<\/p>\n

La CFS, una spin-off del MIT<\/p>\n

has attracted $50 million from Italian energy giant ENI, and plans to invest $30 million of that sum in research and development at MIT over the next three years.<\/p>\n

L’investimento dovrebbe suscitare l’interesse e ulteriori finanziamenti del governo sperano i fondatori dell’azienda, tutti con dottorati (veri) e anni di ricerca alle spalle. Dicono che un prototipo del reattore SPARC produrr\u00e0 elettricit\u00e0 entro 15 anni<\/a>.\u00a0Dal com. stampa<\/a> del MIT:<\/p>\n

\u201cToday is a very important day for us,\u201d says Eni CEO Claudio Descalzi. \u201cThanks to this agreement, Eni takes a significant step forward toward the development of alternative energy sources with an ever-lower environmental impact. Fusion is the true energy source of the future, as it is completely sustainable, does not release emissions or long-term waste, and is potentially inexhaustible. It is a goal that we are increasingly determined to reach quickly.\u201d<\/p>\n

Questa l’ho gi\u00e0 sentita.
\nQuarant’anni fa, un neo-laureato in filosofia inventava un metodo per trasformare i rifiuti in petrolio. Dopo aver tentato invano di piazzarlo in altri paesi, nel 1982 firmava con l’ENI l’accordo commerciale per sfruttare il metodo in tutto il mondo. Dopo un anno e mezzo di esperimenti, i tecnici dell’ENI concludevano che<\/p>\n

la scadente qualit\u00e0 dei liquidi prodotti ne rende problematico l’utilizzo senza ulteriori e costosi trattamenti,\u00a0inoltre\u00a0la presenza di composti clorurati rende improponibile la possibilit\u00e0 di impiego nei forni industriali.<\/p>\n

Questa settimana l’Economist<\/em> celebra<\/span><\/a><\/span> le nuove tecnologie con le quali saranno sfruttate le risorse degli oceani; da accompagnare a “Protect the neglected half of our blue planet<\/span><\/a><\/span>” su Nature<\/em> un mese fa, in cui Glen Wright et al. spiegano come quelle risorse vengono devastate in assenza di accordi internazionali.<\/p>\n

Su Nature Communications<\/em>, Amanda Dawson e altri ricercatori australiani\u00a0scrivono<\/a>\u00a0<\/span><\/span>di aver sottoposto l’Euphausia superba,<\/i>\u00a0il krill antartico, a una dieta di<\/p>\n

PE [polietilene] microbeads (27\u201332\u00b5m diameter) along with an algal food source to determine the fate of microplastics ingested by a planktonic crustacean of high dietary flexibility and ecological importance.<\/p>\n

Dopo cinque giorni in vasca senza plastica, avevano eliminato le microsfere sotto forma di nanosfere:<\/p>\n

We examine exposed krill and their faecal material microscopically to (1) quantify the size of particles present in the krill digestive system and in egested material, (2) identify where these particles are localised within the digestive system, and (3) examine the effect of particle size on egestion. We find that Antarctic krill are capable of fragmenting pristine PE microbeads into significantly smaller fragments, showing that nanoplastics can be generated by the ingestion of microplastics in a marine species.<\/p>\n

Dal Guardian<\/span><\/a><\/em>,<\/p>\n

Unfortunately, Dawson said, krill were unlikely to provide a solution to the levels of plastics and microplastics polluting the oceans.\u00a0\u201cIt\u2019s not necessarily helping plastic pollution, it\u2019s just changing it to make it easier for small animals to eat it,\u201d she said. \u201cIt could be a new source of plastics for the deep ocean.\u201d<\/p>\n

Il Guardian<\/em> ne conclude che nell’Oceano meridionale le balene non mangeranno gamberetti infarciti di microsfere. Anche perch\u00e9 prima di evacuare nanosfere, capita al krill di essere pompato dalla superficie per fornire mangime agli allevamenti ittici o per estrarne gli omega 3\u00a0 e altri lipidi che, stando alle r\u00e9clame,<\/p>\n

favoriscono la regolare funzionalit\u00e0 dell’apparato cardiovascolare, il controllo dei lipidi plasmatici (trigliceridi), influiscono sulla funzione cognitiva, sul processo visivo e sostengono la mobilit\u00e0 articolare.<\/p>\n

Oh my… lo storico David Bell chiama lo psicologo Steven Pinker “The Power Point Philosophe<\/a>“:<\/p>\n

Enlightenment Now<\/em>\u00a0…\u00a0 is a dogmatic book that offers an oversimplified, excessively optimistic vision of human history and a starkly technocratic prescription for the human future. It also gives readers the spectacle of a professor at one of the world\u2019s great universities treating serious thinkers with populist contempt. The genre it most closely resembles, with its breezy style, bite-size chapters, and impressive visuals, is not 18th-century\u00a0philosophie<\/em>\u00a0so much as a genre in which Pinker has had copious experience: the TED Talk (although in this case, judging by the book\u2019s audio version, a TED Talk that lasts 20 hours).<\/p>\n","protected":false},"excerpt":{"rendered":"
