10:54 AM | Graphene reinvents the future
For many scientists, the discovery of one-atom-thick sheets of graphene is hugely significant, something with the potential to affect just about every aspect of human activity and endeavour.

10:50 AM | New DARPA 'Atoms to Product' program seeks to develop advanced nanotechnology
New program also seeks to develop revolutionary miniaturization and assembly methods that would work at scales 100,000 times smaller than current state-of-the-art technology.

9:27 AM | Optical microscope technique confirmed as valid 3D nano-measurement tool (w/video)
Recent experiments have confirmed that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional (3D) shape of objects at nanometer-scale resolution - far below the normal resolution limit for optical microscopy.

9:00 AM | RHIC rivela evidenze indirette di ‘barioni strani ultra pesanti’
A seguito di un recente esperimento realizzato presso il RHIC del Brookhaven National Laboratory, un gruppo di ricercatori ha trovato alcuni indizi relativi ad una particella misteriosa che è stata a lungo ipotizzata e che però non è mai stata rivelata. Finora, queste particelle elusive, denominate “barioni strani ultra pesanti”, non sono stati mai osservati […]

8:11 AM | Researchers film protein quake for the first time
One of nature's mysteries is how plants survive impact by the huge amounts of energy contained in the sun's rays, while using this energy for photosynthesis. The hypothesis is that the light-absorbing proteins in the plant's blades quickly dissipate the energy throughout the entire protein molecule through so-called protein quakes. Researchers have now managed to successfully 'film' this process.

8:00 AM | That’s So Hot
Finally got my FLIR One thermal-IR camera working (the issue was with the phone to which it’s attached), and it’s amazing. This is my kitchen sink, with a bowl full of room-temperature water in it, along with some utensils, and the water on hot, aimed so it hits the basin rather than going straight into [...]

6:00 AM | DES inizia per la seconda survey del cielo sud
Dopo gli ottimi risultati già ottenuti nel corso della sua prima stagione, è già iniziato il secondo anno della missione spaziale denominata Dark Energy Survey (DES), che avrà come obiettivo la survey del cielo meridionale con una accuratezza senza precedenti. Grazie alla risoluzione di 570 megapixel della Dark Energy Camera (DECAM), montata presso il telescopio Victor M. Blanco […]

2:00 AM | The Cold Spot is not particularly cold
(and it probably isn't explained by a supervoid; although it is still anomalous)In the cosmic microwave background (CMB) there is a thing that cosmologists call "The Cold Spot". However, I'm going to try to argue that its name is perhaps a little, well, wrong. This is because it isn't actually very cold. Although, it is definitely notably spotty.That's the cold spot. It even has its own Wikipedia page (which really does need updated).Why care about a cold spot? This spot has become a thing to […]

1:58 AM | Government Graphics Galore; How much of our tax dollars are going towards science?
Click to expand: A taste of what is to come...This graphic offers an international comparison of the percent of their GDP that countries invest in the defense and non-defense categories of their R&D budgets. As someone who's salary is coming directly from the National Science Foundation (NSF), I am a fan of the government dollars. This also means I'm a little fed up with Congress' love of cutting funding for the sciences. In the aftermath of the sequester, and the […]

8:37 PM | Woodpecker Bodies Cushion Collision Impact On Bird Brains
Originally published: Aug 25 2014 - 10:30am, Inside Science News ServiceBy: Katharine Gammon, Contributor(Inside Science) -- Woodpeckers are some of the most industrious birds in nature. Their intense tapping -- all an elaborate effort to procure food -- can happen as rapidly as 20 pecks per second, with each strike transmitting a seemingly brain-rattling force of up to 1,200 times the force of gravity at Earth's surface.Yet, despite those repetitive impacts, woodpeckers typically show none of […]

ContextTechnology,Neuroscience,Computing by Tom Siegfried 5:00pm, August 26, 2014 René Descartes was a very clever thinker. He proved his own existence, declaring that because he thought, he must exist: “I think, therefore I am.”But the 17th century philosopher-mathematician-scientist committed a serious mental blunder when he decided that the mind doing the thinking was […]

In particolare uno tra ATLAS e CMS, i due esperimenti giunti agli onori delle cronache per la scoperta del bosone di Higgs.E' possibile, infatti, da un paio di settimane, giocare a Particle Clicker, un bel gioco gestionale che fa comprendere quanto sia complesso, ma anche gratificante gestire un esperimento scientifico come uno dei due citati prima.Innanzitutto la schermata: è suddivisa in quattro frame. Da sinistra a destra: nel primo sono elencati i risultati di ricerca ottenuti con […]

7:13 PM | Scientists craft atomically seamless semiconductor junctions only three atoms thick
Researchers have demonstrated that two of these single-layer semiconductor materials can be connected in an atomically seamless fashion known as a heterojunction. This result could be the basis for next-generation flexible and transparent computing, better light-emitting diodes, or LEDs, and solar technologies.

5:59 PM | Our Neighboring Superstars
The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the Sun, it is also extremely volatile and is expected to have at least one supernova explosion in the future. As one of the first objects observed by NASA's Chandra X-ray Observatory after its launch some 15 years ago, this double star system continues to reveal new clues about its nature through the X-rays it […]

3:59 PM | Black holes into darkness
Black holes are gravity at the extreme. As such, many of their properties lie at the edge of our knowledge of physics. At the event horizon — the boundary beyond which nothing can return to the outside Universe — we must grapple with the combination of gravity and quantum physics, a problem we have yet […]

3:39 PM | Holometer, un esperimento per studiare la natura dell’Universo
Se vedete in dettaglio lo schermo del vostro televisore noterete dei pixel, piccoli punti di dati che formano una immagine senza soluzione di continuità se ci allontaniamo. Gli scienziati ritengono che l’informazione contenuta nell’Universo sia contenuta allo stesso modo in una specie di “pixel spaziali” la cui dimensione naturale è 10 trilioni di trilioni di volte […]

2:59 PM | More magnet work and a bit of attenuation: Lab Book 2014_08_26
Summary:  It was a somewhat uneventful day.  Current carrying cables to connect the power supply and the iron yoke magnet were constructed.  A detector longer run was made with the Cd 109 source, but the peak resolution did not improve. If you're new to the experiment, scroll to the bottom for background.Six gauge quarter inch copper crimp lugs were attached to the ends of two lengths of cable.  These cables will transmit current from the power supply to the magnet.To Do:Add […]
