1:03 PM | Failure Is Always An Option
Do not try this at home. A Russian Proton-M launch goes wrong – and it can happen to anyone (wait for the shock wave). A rocket is a controlled bomb. The fully fueled Saturn V ‘moon... -- Read more on ScientificAmerican.com

11:43 AM | Cosa c'era a bordo del razzo Antares
Come ha assicurato la Nasa, l'esplosione del razzo Antares di ieri non dovrebbe rappresentare un problema per l'equipaggio della Stazione Spaziale Internazionale, che nei prossimi giorni riceverà nuovi rifornimenti da un veicolo dell'agenzia spaziale russa. Se gli astronauti dell'Iss possono tirare un sospiro di sollievo, per altri l'incidente rappresenta invece un problema più serio. Tra le vittime dell'esplosione c'è infatti Arkyd 3, un piccolo veicolo spaziale progettato […]

11:15 AM | Popeular Science
On Monday, Pope Francis was speaking at the Pontifical Academy of Sciences and dropped something of a bombshell: He said that the Big Bang and evolution are not contrary to Catholic beliefs. What’s funny to me is that for people paying attention, these statements aren’t bombshells at all. To me it’s not newsworthy that he said these things, it’s newsworthy that people think they’re newsworthy. Part of it is understandable. After all, it was the Catholic Church that […]

8:50 AM | Video, esplode un razzo diretto alla Stazione spaziale
Erano da poco passate le 6:22 p.m. (22:22 GMT) alla Wallops Flight Facility della Nasa (Virginia) quando il razzo Antares della Orbital Science Corporation carico del veicolo di rifornimento per laStazione spaziale internazionale (senza equipaggio) Cygnus èesploso. Era passato appena qualche secondo dal via e poi una palla di fuoco in aria, e quindi di nuovo sul trampolino di lancio. Bruciando anche il carico a bordo del razzo è andato […]

7:07 AM | Deepwater Horizon: un quinto del petrolio è sul fondo del mare
Un disastro totale. Iniziato male e finito anche peggio. Le conseguenze dell'incidente della Deepwater Horizon, la piattaforma petrolifera di proprietà Transocean affondata il 20 aprile 2010 nel Golfo del Messico, come vi abbiamo raccontato, sono state tremende. Oltre a costare la vita a 11 persone, l'incidente ha provocato un gravissimo danno ambientale. In mare si sono riversati circa 5 milioni di barili di petrolio, che hanno provocato la distruzione di un intero ecosistema. L'oro […]

6:00 AM | Forward by Failure
A few years ago, I decided to take up hunting. This was kind of a big deal, because I’d spent the first decade-plus of my adult life as vegetarian. I became a big game hunter for the same reason I raise chickens — to know where my food comes from and ensure that it’s raised […]

4:00 AM | Ancora domande aperte sul quark-top
In un post dello scorso mese di Febbraio, ho pubblicato la notizia relativa ad un metodo trovato dai fisici che lavorano agli esperimenti CDF e DZero presso il Fermi National Accelerator Laboratory che ha permesso di produrre un quark-top attraverso l’interazione debole. Oggi, dopo quasi 20 anni dalla sua scoperta, avvenuta proprio al Fermilab nel 1995, gli scienziati sono ancora […]

1:09 AM | The Conquest of Space is Worth the Risk
Orbital Sciences Mission Explodes 6 Seconds Into Launch No doubt you’ve seen the video below, showing the Orbital Sciences Corporation Cygnus cargo spacecraft expl0ding shortly after liftoff. This is an unfortunate catastrophe for Orbital Sciences, but also for the many people (including a number of students) who had experiments and other instruments aboard. NASA, the […]

11:14 PM | BREAKING: Antares Rocket Explodes on Takeoff
Update, Oct. 29, 2014 at 01:30 UTC: A NASA press conference was held a few hours after the explosion; here's a rundown. They told people not to pick up any debris they might find near the launch site, because it might be dangerous. The launch pad was damaged by the explosion, but it's not clear yet how badly (night fell around the time of launch, so it's dark in the area). As expected, they won't comment on the possible cause of the accident, but did say the astronauts on ISS are in no danger; […]

10:00 PM | “He-Man” Writer Is Not The Master Of The (copyright) Universe.
Mattel Inc. has won a copyright case involving a former freelance writer of “He-Man” mini comics. Donald Glut was hired in 1981 to create the comics to develop the backstories of Mattel’s “Masters of the Universe” toy characters, including “He-Man.” After Glut threatened to sue Mattel to enforce his claimed rights in Mattel’s toy line, … Continue reading →

5:24 PM | Into the Woods (Synopsis)
Wandering into the woods unprepared and without a plan sounds like a terrible idea. But if you’re interested in scientific exploration at the frontiers, confronting the unknown with whatever you happen to have at your disposal, you have to take that risk. You have to be willing to take those steps. And you have to…

4:15 PM | Chang'e 5 T1 rounds the lunar farside, returns lovely photo of Earth and the Moon together
The Chang'e 5 test vehicle's short mission is more than half over. It has rounded the far side of the Moon and is on its way back to Earth for a planned October 31 test of lunar sample return technology. It's not a science mission -- it's an engineering mission -- but it has managed to return an absolutely iconic photo of its distant home, seen across the very unfamiliar far side of the Moon.

4:05 PM | Il robot che muove gli oggetti con l'elettricità statica
Avete mai provato a strofinare una bacchetta di plastica - una penna, per esempio - su un panno di lana e ad avvicinarla a un pezzo di carta? È il più classico degli esperimenti scientifici delle scuole elementari. La bacchetta, come per magia, attira a sé la carta: tutto merito dell'elettricità statica, ovvero l'accumulo (nel nostro esempio, dovuto allo sfregamento) di cariche elettriche su un corpo isolante. Se sollevare un po' di carta vi sembra poco, […]

1:35 PM | Tethying Rings
So far over the past week or two I’ve covered a lot of ground in the solar system, from Mercury to Pluto, back to Mars, then in to the Sun. So let’s head back out and see what’s going on at Saturn. Oh, just this: Oh, do I love some good ol’ Saturn photo amazingness! What you’re seeing is Saturn’s moon Tethys right through Saturn’s rings, which are very nearly edge-on in this shot. The Cassini space probe was about 1.8 million km (1.1 million miles) from […]

1:31 PM | La memoria migliora davvero col cioccolato?
Anno dopo anno, col passare del tempo, non è solo il corpo a cambiare ma anche la mente invecchia e la memoria potrebbe iniziare a giocare qualche scherzo: ricordare il volto di una persona appena conosciuta o il posto in cui si è parcheggiata l’auto diventa più faticoso. Ma a risollevare gli animi, specialmente dei più golosi, ci prova oggi uno studio dei ricercatori del Columbia University Medical Center pubblicato su Nature Neuroscience, suggerendo che […]

1:03 PM | La fibra ottica più veloce del mondo
255 terabit al secondo: è questo il nuovo record del mondo di velocità di trasmissione su fibra. A realizzarlo è stato un gruppo di ricercatori olandesi e americani, della Eindhoven University of Technology (TU/e) e della University of Central Florida (Creol), che in un articolo apparso su Nature Photonics ha illustrato le potenzialità di una nuova fibra ottica, che può superare di ben 20 volte la capacità di banda delle reti attuali. Una possibile […]

12:46 PM | Ghostly Physics (Synopsis)
You’ve no doubt heard of quantum entanglement before: the idea that if you create a mixed quantum state that consists of two particles, you can then know the properties of one by measuring the properties of the other. The odd — and counterintuitive — thing about this is that once these particles are entangled, you…

9:47 AM | La supermacchia solare e i brillamenti da record
Macchie così, sul Sole, non se ne vedevano dal 1990. Stiamo parlando dell'eccezionale sunspot (macchia solare) che da qualche tempo è visibile sulla nostra stella, grande più o meno quanto il pianeta Giove. Ma la regione AR2192 non è solamente maestosa: è anche straordinariamente attiva. Negli ultimi giorni infatti ha sparato una serie di potenti solar flares (brillamenti solari), improvvisi lampi di luce altamente energetici. I brillamenti solari sono, […]
