4:22 AM | Talk - 3D printing with atoms?
A recent University of Nottingham Science Lecture featured a fascinating talk by Prof Philip Moriarty. The talk was entitled "3D printing with atoms?" and looked at how researchers can now image and manipulate individual atoms to create rudimentary atomic scale structures. This post is based on the talk, with some added linkage thrown in... Prof Moriarty began by explaining that the "?" in the talk title was important - and that the answer was no, we cannot currently "print" with individual […]

4:01 AM | Few Words with Much Meaning
  In 1972, Chief Jimmy Bruneau of the Tłı̨chǫ First Nation attended the opening of the school that would bear his name. As part of the ceremony, many dignitaries got up to the microphone before him and gave long-winded speeches. Bruneau was an old man and very ill (he would die three years later), so […]

10:00 PM | Fracking Chemicals And Tradesecret Protection.
A US Department of Energy advisory panel has stated that oil and gas companies should not seek trade secret exemptions to conceal the nature of substances added to fluids used in fracking. Fracking (more formally known as “hydraulic fracturing”), is a process by which fluids (commonly water) are mixed with sand and chemicals and then … Continue reading →

3:39 PM | Perché alcuni di noi sono più suscettibili allo stress?
Perché alcuni di noi di fronte alle difficoltà soccombono allo stress, sviluppando ansia o depressione, mentre altri sembrano resistere senza problemi? Una possibile risposta potrebbe arrivare da uno studio condotto da Carla Nasca, una giovane ricercatrice Italiana che oggi lavora alla Rockefeller University di New York. La ricerca, pubblicata sulla rivista Molecular Psychiatry, ha identificato infatti i meccanismi molecolari del cosiddetto Stress Gap, una scoperta che potrebbe […]

3:35 PM | Ice to See You
The last place in the solar system you’d expect to find ice (except maybe on the Sun, duh) is Mercury. Rocky, barren, airless, and very, very hot, Mercury doesn’t sound like the ideal location for storing vast quantities of frozen water. But in the 1990s evidence started coming in that perhaps Mercury was holding a surprise. At its north pole are deep craters, and because of their high latitude, the low Sun never reaches the crater floors. They’re permanently dark, and because […]

2:29 PM | Google offrirà servizi medici?
Sembra che Big G si prepari a lanciare un nuovo servizio che mette in contatto diretto pazienti e medici, attraverso delle videochat. La prima indiscrezione è emersa grazie a uno screenshot pubblicato sul forum Reddit ed è stata poi confermata da Google su Endgadget e Gizmodo. Attualmente il servizio è nella fase di test. Il sistema, a partire dalle query effettuate sul motore di ricerca, dovrebbe proporre la possibilità di parlare con uno specialista. Per esempio, […]

1:24 PM | HD 97658b, una super-Terra identificata con la tecnica della spettroscopia
Gli studi effettuati sul nostro Sistema Solare non ci permettono di arrivare a conclusioni certe in merito alle caratteristiche che esso può avere in comune, o meno, con gli altri sistemi planetari. Tuttavia, da quando la NASA nel 2009 ha messo in orbita il satellite Kepler, le cose stanno cambiando e oggi abbiamo una lista di […]

1:12 PM | The E-cat: cold fusion or scientific fraud? (Synopsis)
“There’s a mark born every minute, and one to trim ‘em and one to knock ‘em.” -David W. Maurer, The Big Con (1940) But how could you tell? There’s lots of amazing science going on out there, and none of us can be experts in it all. Moreover, even when we think we know how things…

1:11 PM | What happened in the first instants after the Big Bang?
One of the biggest science stories of 2014 came out of the BICEP2 cosmic microwave background polarization experiment. Last spring, the BICEP2 researchers announced they had measured something known as B-mode or tensor-mode polarization, a particular twisting of light that is the hallmark of primordial gravitational waves. Those waves in turn would be a strong […]

12:14 PM | Dos Andes Peruanos às Galáxias e à origem do Universo
Há um século o nosso Universo era apenas a Via Láctea, mas hoje sabemos que existem bilhões de galáxias como a nossa espalhadas na imensidão do cosmos, e sabemos que o Universo está em expansão e que teve origem no Big Bang. Os Andes Peruanos tiveram um papel fundamental nessas descobertas.Edwin Hubble demostrou há menos de um século que certas "nebulosas" eram na verdade galáxias como a nossa Via Láctea. Ele […]

11:30 AM | To Pluto … AND BEYOND!
In July of 2015, the New Horizons space probe will whiz past Pluto, traveling at 40,000 kilometers per hour. For several weeks before and after the close flyby—it’ll pass within 10,000 km above the tiny world’s surface—it will examine Pluto, its moons, and the environment around it. But this is not an orbiter, or a lander. Pluto is 5 billion kilometers from Earth, and the only way to get a probe there in any decent amount of time was to strip it down as light as possible […]

4:29 AM | From the Peruvian Andes to galaxies and the Big Bang
A century ago our universe was just a little village called the Milky Way. Today, we know that there are billions of galaxies in the cosmos, and that the universe is expanding due to the Big Bang. The Peruvian Andes played a fundamental role in those discoveries.Less than a century ago, Edwin Hubble showed that certain "nebulae" are actually galaxies like our Milky Way, by using the so-called period-luminosity relationship of variable stars known as cepheids, that allowed him to estimate […]

12:36 AM | A Comet Passes by Mars; An Eclipse of the Sun
 On Thursday afternoon, Oct. 23, there will be a partial eclipse of the Sun, visible from the U.S. Different amounts of the Sun's area will be covered by the Sun. (For example, 40% of the Sun will be covered from the San Francisco region.) I have put question-and-answer introductions to the eclipse at: http://www.astrosociety.org/society-news/2014-eclipse-fact-sheets/ You can consult the national sheet for the degree the Sun will be eclipsed in your area. Here's wishing everyone […]
