4:34 PM | NASA's plan to find asteroids is falling short
The orbits of all currently-known near-Earth asteroids larger than the 140-meter limit set by the US Congress.  (Image credit: NASA/JPL) Our solar system is chock full of asteroids - millions of them.  While most are contained within the asteroid belt that lies between Mars and Jupiter, these rocks can be found pretty much anywhere in the solar system.  Many scientists believe that the majority of asteroids are composed of material left over from the formation of […]

2:35 PM | Pulling secrets from deep-sea, drillbit-eating rocks
Amy West is the science writer and outreach and education officer for the JOIDES Resolution, a drill ship operated by the International Ocean Discovery Program (IODP) that is on a two-month expedition studying the Izu-Bonin-Mariana Arc in the region where the Pacific Plate is descending under the Philippine Plate to form the Mariana Trench and the deepest point in the ocean–the Challenger Deep. This is her latest blog post about the expedition.

2:28 PM | Nel 2015 la cannabis terapeutica prodotta in Italia
Finalmente c’è un accordo: entro il 2015, racconta l’Ansa, i malati italiani affetti da malattie neurodegenerative e che necessitano di terapia del dolore, potranno aver accesso a farmaci a base di cannabis terapeutica prodotti in Italia. Che quindi costeranno molto meno rispetto a quelli attualmente importati dall’estero, il cui prezzo è di circa 15 euro al grammo. Un bel risparmio, insomma. I termini della collaborazione siglata […]

12:53 PM | IgNobel, le ricerche più improbabili del 2014
Secondo un antico proverbio toscano, più che appropriato quando si parla di IgNobel, “la scienza è follia, se il senno non la governa”. E sembrerebbero folli e fuori di senno (ma che fanno anche riflettere) le dieci ricerche scientifiche premiate ieri al Sander Theatre dell’Università di Harvard durante la cerimonia organizzata dalla rivista Annals of Improbable Research, che dal 1991 assegna un premio simbolico alle ricerche più “strane, […]

11:38 AM | Nuovi segni per la materia oscura
Vi ricordate l’Alpha Magnetic Spectrometer (Ams)? Be’, il cacciatore di antimateria (e non solo, qui un ripassino sulle caratteristiche della missione), dopo i segnali resi noto lo scorso anno infatti, potrebbe aver visto ancora qualcosa di interessante. Ams  – sostanzialmente un rivelatore di particelle provenienti dai raggi cosmici, montato sulla Stazione spaziale internazionale – avrebbe rivelato nuovi indizi […]

8:00 AM | The Floating World of Jellyfish
In a dark gallery alongside Baltimore’s Inner Harbor, a horde of glowy, gelatinous bulbs are drifting. A living lava lamp, someone calls them, and that’s what they are – jellyfish, mesmerizingly lit for the benefit of visitors to the National Aquarium in Baltimore. Aquariums have been keeping jellies for years. I first saw them at […]

6:25 AM | Un "robot indossabile" che aiuta a camminare
È leggero, poco ingombrante, costruito con materiali flessibili che si adattano ai movimenti del corpo e si indossa come un paio di pantaloni. Si tratta di un prototipo di esoscheletro al quale stanno lavorando gli scienziati del Wyss Institute for Biologically Inspired Engineering, presso l’Università di Harvard, finanziato dalla Defense Advanced Research Projects Agency(Darpa) con 2,9 milioni di dollari.Il robot, chiamato Soft Exosuit, è pensato per potenziare i […]

5:30 AM | It’s a Galaxy-Eat-Galaxy Cosmos Out There
Monster Galaxies Nibble On Smaller Ones to Get  Bigger Galaxies grow by eating other galaxies — that’s a given in the cosmos. It’s also true that galaxies spend much of their productive lives making stars from the gas they contain. These two galactic activities began with the first proto-galactic “shreds” that began to combine to grow […]

4:00 AM | LHC, prossimo obiettivo le superparticelle
La scoperta della particella di Higgs ha rappresentato una svolta fondamentale per la ricerca nel campo della fisica delle particelle, anche se molti scienziati ritengono che siamo solo all’inizio (post). Infatti, quando il grande collisore adronico (LHC) entrerà in funzione nel 2015, operando ad un livello di energia quasi il doppio rispetto agli esperimenti precedenti, […]

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” -Carl Sagan That might be true: all the heavy elements — in theory — were created after at least one generation…

10:17 PM | Two developments in commercial spaceflight this week
NASA plans to turn to private companies for crew transport.  (Image credit: NASA) With tensions between Russia and the West remaining high, NASA is moving ahead with plans to find a homegrown method for delivering astronauts to Earth orbit.  The agency's own Orion capsule, designed to transport crews to asteroids, the Moon, and beyond is still years from completion, so in the interim it will be up to commercial enterprises to be our taxis.  A field that barely […]

10:00 PM | How The Copyright “Anti-Circumvention” Problem Can Affect You.
The Electronic Frontier Foundation was before Congress asking  lawmakers to abandon or modify the “anti-circumvention” provisions of the Digital Millennium Copyright Act (DMCA).  The “anti-circumvention” provisions of the Copyright Act, bar circumvention of access controls and technical protection measures.  Congress intended the change to stop pirates from defeating DRM and other content access or copy … Continue reading →

7:38 PM | How a Planet Can Mess Up a Star's Looks
Note: An earlier version of this article appeared on Peter Edmonds' blog. Recently, beautiful photos of auroras have been in the news. These colorful light shows were generated by solar storms, and provide a vivid demonstration of activity on the Sun affecting the Earth. The pummeling experienced by our home planet is an example of our one-way relationship with the Sun: it can have a noticeable effect on the Earth, but the Earth has a negligible effect on the Sun. Further afield in the galaxy, […]

Recently, beautiful photos of auroras have been in the news. These colorful light shows were generated by solar storms, and provide a vivid demonstration of activity on the Sun affecting the Earth. The pummeling experienced by our home planet is an example of our one-way relationship with the Sun: it can have a noticeable effect on the Earth, but the Earth has a negligible effect on the Sun. Further afield in the galaxy, this isn't always the case. In a few other systems planets canhave a big […]

4:01 PM | Come affrontare il tumore del colon retto
“Tutti possiamo diventare pazienti a un certo punto della vita: non possiamo quindi permetterci di essere disinformati, pensare che non ci riguardi. A maggior ragione per una patologia come il cancro al colon retto che è molto diffusa, ma di cui c’è molta poca consapevolezza, anche a causa della parte del corpo interessata, una parte di cui nessuno ha voglia di parlare”. Jolanda Gore-Booth è una donna energica, che da 20 anni si batte per i diritti dei […]
