Santiago (AFP) Feb 28, 2013 – Astronomers using a powerful telescope in southern Chile said Thursday they have captured the first direct image of a protoplanet forming around another star, still embedded in thick gas and dust. An international team of researchers said the disc of gas and dust surrounding the young star HD 100546, located 335 light years from Earth in the Milky Way galaxy, would be a gas giant similar to … more

Tungstenite triangles emit light
London, UK (SPX) Feb 28, 2013 – Researchers in the US have succeeded in growing single atomic layers of the naturally occurring mineral tungstenite for the first time. The sheets appear to have unusual photoluminescence properties that might be exploited in optics devices like lasers and light-emitting diodes. 2D materials have dramatically different electronic and mechanical properties from their 3D counterparts and so … more

Force is the Key to Granular State-Shifting
Raleigh NC (SPX) Feb 28, 2013 – Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It’s because granular materials – like sand or dirt – can change their behavior, or state. Researchers from North Carolina State University have found that the forces individual grains exert on one another are what most affect that transition. Physicists have explored the changing … more

Theory of crystal formation complete again
Eindhoven, Netherlands (SPX) Feb 28, 2013 – Exactly how a crystal forms from solution is a problem that has occupied scientists for decades. Researchers at Eindhoven University of Technology (TU/e), together with researchers from Germany and the USA, are now presenting the missing piece. This classical theory of crystal formation, which occurs widely in nature and in the chemical industry, was under fire for some years, but is saved … more
