3:02 PM | Scoperta la causa della malattia di Erdheim-Chester
La malattia di Erdheim-Chester, una patologia rara in cui alcune cellule del sistema immunitario (gli istiociti) invadono e distruggono diversi tessuti dell’organismo, da oggi ha una causa nota. In uno studio pubblicato sugli Annals of the Rheumatic Diseases, i ricercatori dell'Ospedale San Raffaele di Milano hanno ricondotto la malattia ad una mutazione del gene Braf, capace di attivare un processo infiammatorio incontrollato nelle cellule portatrici. La malattia di Erdheim-Chester ha […]

1:56 PM | Esercizi fisici per curare l'eiaculazione precoce
Un rimedio “naturale” per i tre milioni e mezzo di italiani che soffrono di eiaculazione precoce: la ginnastica. È quanto emerge da un nuovo studio presentato da Antonio Pastore, urologo della Sapienza Università di Roma, al Congresso Europeo di Urologia di Stoccolma: esercitare i muscoli del pavimento pelvico sembra essere efficace per durare più a lungo sotto le lenzuola, anche nelle persone che non rispondono ai trattamenti farmacologici tradizionali. Secondo […]

1:55 PM | Contro l’artrite meglio le erbe cinesi dei farmaci
Un antico rimedio a base di erbe medicinali cinesi sembrerebbe più efficace delle terapie farmacologiche prescritte dai medici per l’artrite reumatoide. È il risultato che emerge da uno studio pubblicato on-line dai ricercatori del Peking Union Medical College Hospital di Pechino sugli Annals of the Rheumatic Diseases. L’erba medicinale esaminata è il Tripterygium wilfordii Hook F (TwHF), nota come “vite del dio del tuono”, usata nella medicina […]

12:38 PM | Intel community willing to allow higher resolution commercial imagery
For the last few years, commercial satellite remote sensing company DigitalGlobe (and, before its merger with DigitalGlobe, GeoEye) has been lobbying the government to allow it to sell sharper satellite imagery that it’s currently allowed. DigitalGlobe is currently restricted to selling imagery with resolution no sharper than 0.5 meters per pixel, but has been pushing [...]

11:30 AM | Look! It’s a Car on Mars!
Right now, there are five spacecraft at or on Mars (and two more on the way). One of the spacecraft on the surface is of course the rover Curiosity, the plutonium-powered Mini Cooper–size mobile chemistry lab. One in orbit is the Mars Reconnaissance Orbiter, equipped with the fantabulous HiRISE camera, capable of seeing objects a half meter across on the Red Planet. Hey! Curiosity is bigger than a half meter. A lot bigger. Can MRO see it? Why yes. Yes it can. Can you find the rover in the […]

11:27 AM | Una proteina contro la celiachia
Tra le intolleranze alimentari, la celiachia è una delle più comuni e conosciute. Si stima che colpisca circa una persona su 500 e l’unica terapia efficace è una dieta completamente priva di glutine. Almeno per il momento. Una recente ricerca pubblicata sull’American Journal of Gastroenterology propone infatti un metodo innovativo per trattare la celiachia tramite l’elafina, una proteina antinfiammatoria naturale. La strategia è stata sviluppata in […]

8:00 AM | A Hometown Hero, A Foreign Flag
Last Saturday, my daughter and I went to the opening day of Little League season. In our small town of White Salmon, Washington, it’s a day for classic Americana: The players chase their coaches around the bases, the Boy Scouts raise the Stars and Stripes, we sing the Star-Spangled Banner, and a local celebrity throws […]

7:48 AM | Top 25 Wild Bird Photographs of the Week #65
We cannot overstate the dedication of wild bird photographers around the world. Birds are extremely risk-averse and getting close is a time-earned skill born of years learning about their behaviour. Knowledge of your camera is essential with no room for error before this bird takes off. The wild bird photographs in this week’s collection are…

7:14 AM | Le piccole braccia del tirannosauro
13 metri di lunghezza, sette tonnellate di peso, e mascelle enormi, con zanne affilatissime lunghe anche 30 centimetri. Eppure, anche nell’identikit del più terrificante predatore della storia, il Tyrannosaurus Rex, c’è un particolare stonato. Ammettetelo, prima o poi ce lo siamo chiesti tutti: ma cosa ci faceva con quelle inutili braccette atrofiche? Oggi un gruppo di ricercatori della University of Wisconsin–La Crosse ha trovato la risposta a questa domanda, […]

5:35 AM | Cannabis: quali sono gli effetti sul cervello?
Fumare marijuana fa male? E quanto? È un tema su cui si discute da decenni, ma i dati scientifici a riguardo continuano a rimanere contraddittori. Oggi, uno studio della Northwestern University sembra portare nuove prove in favore dei possibili effetti negativi a lungo termine della sostanza. I risultati, pubblicati sulle pagine del Journal of Neuroscience, dimostrerebbero infatti che nei giovani il consumo ricreativo della cannabis può provocare l'alterazione della densità […]

This isn’t rocket science, it’s brain surgery!”  -The Simpsons I bet you’re one of those people who hears a term like “nuclear physics” and thinks that’s hard stuff, way over your head. But in many ways, it’s the easiest of all…

3:55 AM | The romance of mathematics
A couple of weeks ago, I found myself describing to someone how badly I had wished to be a mathematician in college.  Mathematics, I said (much to her surprise!), is the most romantic subject in the world.  As scientists, we explore and describe the nature of reality.  Mathematicians are bound by no such limit.  Like the greatest authors, they get to create entire worlds, realms that simply spring forth from their minds.  But math goes so far beyond even the […]

How did planets originate? This is a question that has puzzled scientists for centuries, but one which they have been able to tackle directly only in the last few decades, thanks to two major developments: breakthroughs in telescope technology and ever-increasing computing power.

7:40 PM | Africa’s Illegal Charcoal Trade Engulfs Cheetah Habitat
In rural northern Tanzania, an African country famous for charismatic megafauna, including free-roaming cheetah and other big cats, impoverished and under-employed Swahili villagers struggle to survive. One way to earn money and make cooking fuel is to cut forests for wood that can be turned into charcoal. It’s an economic and environmental disaster, illegal because it is not sustainable for either wildlife or people. Meet the team that is looking for new ways to create livelihoods while […]

5:54 PM | Vannoni si candida alle europee
C’è uno strano tempismo in tutte le vicende che ruotano attorno al caso Stamina. Qualche giorno fa veniva annunciata la notizia che Davide Vannoni intendeva candidarsi alle europee, proprio mentre i medici di Brescia sospendevano i trattamenti del discusso metodo. Notizia però presto smentita da chi avrebbe dovuto accoglierlo tra le proprie file. Oggi invece arriva l’ufficialità: Vannoni si candida […]

3:42 PM | Watch and/or Hear Me Speak at You About Things
I did a couple of interviews recently that I figured I should let y’all know about. First, I spoke with my pal Desiree Schell on her Science for the People podcast about the recent BICEP2 news about cosmic inflation, as well as the new Kuiper Belt Object that was found in the outskirts of the solar system (I wrote about both stories: here and here, respectively). Desiree also talked to Paul Bogard and my good friend Nicole Gugliucci about other astronomy things in that same […]
