11:30 AM | Happy Easter SUN day!
Today is Easter Sunday, a Christian holiday. It actually has a tie-in with astronomy, since it’s celebrated on the first Sunday after the first full Moon after the March equinox. The equinox was Mar. 20, and the full Moon was Monday (during the lunar eclipse, not so coincidentally), so here we are. As is the case with most holidays in America, there’s a secular component to it as well. In this case, the Easter Bunny (which originated in Germany, incidentally) started out with […]

9:52 AM | Misurare la luce, senza assorbire fotoni
È possibile misurare l'intensità della luce senza utilizzare nemmeno un fotone? Sembra impossibile, eppure è proprio quello che hanno fatto Francesco Morichetti e Marco Carminati, due giovani ricercatori del Politecnico di Milano, che hanno realizzato e brevettato il primo “osservatore di luce” non invasivo, che non necessita di assorbire fotoni. Una scoperta estremamente importante nel campo dell'elettronica, come messo in evidenza anche da un articolo su […]

4:56 AM | silent storms
Happy Easter Sunday: the first Sunday after the Full Moon that occurs on or after the vernal equinox. they really take the hot cross buns tradition seriously here in australia. i've eaten SO MANY in recent weeks since they're all over the farmer's markets. i dont think i knew what they actually were until i moved here - small, square fruit bread. yum! now enjoy this timelapse of some fantastic northern lights sequences over norway.

10:52 PM | Eta Carinae 04 / Il "figlio" dell'Homunculus
Passando dall’esterno all’interno della Nebulosa Homunculus, uno studio pubblicato nel 2003 su The Astronomical Journal a firma di molti autori annunciava alla comunità scientifica la scoperta di un “omuncolo” più piccolo, opportunamente battezzato “Little Homunculus”, annidato in quello più grande.La scoperta nasceva dall’attento confronto di una serie di osservazioni di Eta Carinae fatte tra il 1998 e il 2000 con lo […]

7:39 PM | Overfishing Remains Biggest Threat to Mediterranean, Study Confirms
Marine Ecologist Sala says a new study produced by a dozen researchers supports the projection that the Mediterranean is on a trajectory to become a sea dominated by small tropical species that no one likes to eat. "Fishes will not be abundant, and the native species that the Greeks and Romans started to fish commercially will be rare -- and most fisheries and the jobs they support will collapse. But this could change if we stop all the irrational overfishing, including both legal and illegal […]

11:30 AM | That’s No Moon… Well, Actually, Yeah It Is
So there’s a picture you don’t see every day. Clearly, Vader’s forces were not at all happy about the lunar eclipse.  I know, it really does look like the Moon was shooting out a laser at a passing ship, but that’s an illusion: in fact, that laser is hitting the Moon, and it was sent from Earth. While you and I were busy watching the total lunar eclipse on Monday, a bunch of astronomers were zapping it with high-powered lasers. They do this every now and again to […]

April 14 – 18 Our boy, Abstruse Goose, becomes as one with his electronic devices.  Truer than he knows.  Well.  I don’t know what he knows.  Truer than you might think, anyway. Poor Jessa, age 35, thinking about losing her math abilities.  And yes, mathematicians do have the reputation of topping out young.  But Jessa, […]

6:44 AM | Nuove memorie magnetiche per abbattere i consumi
Una nuova tecnica promette di rivoluzionare il funzionamento delle memorie digitali (come i dischi rigidi dei computer), aumentandone incredibilmente l'efficienza e diminuendo di conseguenza i consumi energetici. La scoperta arriva dal centro di ricerca Elettra Sincrotrone Trieste di Area Science Park, ed è frutto del lavoro di un gruppo di ricerca internazionale, a cui hanno partecipato il Consiglio nazionale delle ricerche (Cnr) e il Politecnico di Milano. L’esperimento, […]

1:07 AM | Incredibe: SpaceX Dragon Capsule Video Taken from the Ground!
Thierry Legault is a gifted astrophotographer renowned for his footage of the International Space Station and (once upon a time) the Space Shuttle that he takes through his telescope. His ability to capture these rapidly moving objects is nothing short of spectacular, and I always think there's no way he can top what he's already done. Then I see this: Video of the SpaceX Dragon capsule in orbit a mere 25 minutes after launch! Incredible. This is seriously amazing work; being able to spot the […]

2:49 PM | Ecco il drone stampato in 3D
In gergo tecnico si chiama unmanned aherial vehicle (Uam). Più colloquialmente, è un drone di un metro e mezzo messo a punto dagli ingegneri dell'Advanced Manufacturing Research Centre (Amrc) alla University of Sheffield: la sua particolarità è che è stato stampato in 3D grazie a una nuova tecnica sviluppata dagli scienziati britannici, chiamata fused deposition modelling. Le versioni attualmente in produzione, spiegano gli autori della ricerca, richiedono […]

2:47 PM | Il complesso ruolo della guaina mielinica
La guaina mielinica è una struttura biancastra che avvolge gli assoni dei neuroni, e permette di trasmettere velocemente i segnali nervosi all'interno del cervello. Fino ad oggi si riteneva che tutti i neuroni avessero lo stesso tipo di guaina mielinica, ma un nuovo studio dell'Università di Cambridge, a cui hanno collaborato anche i ricercatore dell'Università di Torino, mette oggi in dubbio questo paradigma. I risultati, pubblicati sulle pagine di Science, suggeriscono […]
