6:30 PM | Thunderstorm of the night of Perseids
The night between 12th and 13th of August should have been a Perseid spectacle, but Moon and thunderstorms stole the show from Perseids. The thunderstoms of last night was easily one of the best thunderstoms shows that I have ever witnessed!

6:20 PM | Astroboy: L'uomo elettrico
L'uomo elettrico, primo vero episodio della serie a fumetti di Astro Boy, è utilissimo per introdurre il discorso tecnico che non ho scritto nel primo articolo della serie.Dal punto di vista narrativo, siamo di fronte a una storia dickiana dal ritmo veloce, un vero e proprio hard boiled degli androidi, nel quale confluisce anche il cinema thriller statunitense alla Hitchcock, basti pensare alla tensione trasmessa dalla sequenza qui a destra (che non è l'unica del suo genere).Anche […]

4:47 PM | New test reveals purity of graphene
Graphene may be tough, but those who handle it had better be tender. The environment surrounding the atom-thick carbon material can influence its electronic performance, according to researchers who have come up with a simple way to spot contaminants.

3:45 PM | Is the P vs. NP problem ill-posed? (Answer: no.)
A couple days ago, a reader wrote to me to ask whether it’s possible that the solution to the P vs. NP problem is simply undefined—and that one should enlarge the space of possible answers using non-classical logics (the reader mentioned something called Catuṣkoṭi logic).  Since other people have emailed me with similar questions in […]

1:21 PM | SEFT-1, Crossing Mexico In A ‘Spacecraft’
Meet SEFT-1, Sonda de Exploración Ferroviaria Tripulada (or Manned Railway Exploration Probe) In the latter part of the 19th Century, the Mexican government partnered with British companies to build a railway line connecting Mexico City with the Atlantic Ocean. Since that time the passenger railways have fallen out of use, leaving thousands of kilometers of […]

8:42 AM | Eat Lead! And Nickel, and Mercury, etc.
Cleaning Up Polluting Mines With Plants–Plants That Then Turn Into Precious Metals Interesting. Though I wonder what happens to animals that eat the plants (or eat the insects that eat the plants), or if the metal content makes them so unpalatable that it isn’t an issue. Or do you just have to fence it all [...]

8:08 AM | A convenient method to chemically modify boron nitride nanotubes
So far, it has been generally accepted knowledge that boron nitride nanotubes (BNNTs) are highly inert to oxidative treatments and can only be covalently modified by highly reactive species. By contrast, oxidation of carbon nanotubes has been proven very convenient and fundamentally important to modify the nanotube structure and morphology via controlled corrosive effects. Now, researchers have discovered a convenient method to disperse and chemically modify the morphology of BNNTs by […]

4:00 AM | L’inquinamento atmosferico come strumento d’indagine per la ricerca di ET
Mai come oggi, l’umanità si trova “vicina” alla soglia della rivelazione di segni di vita extraterrestre su altri mondi. Lo studio delle atmosfere planetarie può rappresentare un ottimo strumento d’indagine per identificare alcuni gas come l’ossigeno ed il metano che possono esistere solamente se vengono riforniti da forme di vita semplici, come ad esempio i microrganismi.

9:55 PM | Astroboy: nascita di Atom
Come per tutti i supereroi che si rispettino, anche per Atom arrivano le sue origini segrete, e in questo caso costituiscono l'inizio effettivo della serie Tetsuwan Atom di Osamu Tezuka, la mitica serie Astro Boy. Parallelamente alla serializzazione di Pluto, reinterpretazione da parte di Naoki Urasawa de Il più grande robot del mondo, uno degli episodi della serie originale, la Panini propone in una serie di 5 volumi la ristampa della serie nota in Italia come Astro Boy. Tale serie di […]
