Snow in an Infant Planetary System
Munich, Germany (SPX) Jul 19, 2013 – A snow line has been imaged in a far-off infant planetary system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae, promises to tell us more about the formation of planets and comets, the factors that decide their composition, and the history of the Solar System. The results are published in Science Express. Astronomers using the Atacama Large M … more

Link between quantum physics and game theory found
Bristol, UK (SPX) Jul 17, 2013 – While research tends to become very specialized and entire communities of scientists can work on specific topics with only a little overlap between them, physicist Dr Nicolas Brunner and mathematician Professor Noah Linden worked together to uncover a deep and unexpected connection between their two fields of expertise: game theory and quantum physics. Dr Brunner said: “Once in a while, co … more

Ingested nanoparticle toxicity
Indianapolis IN (SPX) Jul 01, 2013 – Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance. Writing in a forthcoming issue of the International Journal … more

Nanoparticle Opens the Door to Clean-Energy Alternatives
University Park PA (SPX) Jun 18, 2013 – Cheaper clean-energy technologies could be made possible thanks to a new discovery. Led by Raymond Schaak, a professor of chemistry at Penn State University, research team members have found that an important chemical reaction that generates hydrogen from water is effectively triggered – or catalyzed – by a nanoparticle composed of nickel and phosphorus, two inexpensive elements that are abund … more

Sun-Grazing Comet Flies Deep Into Solar Corona
Palo Alto CA (SPX) Jun 12, 2013 – On December 15-16, 2011, a Sun-grazing comet, designated Lovejoy (C/2011 W3), passed deep within the hot solar atmosphere – the corona – effectively probing a region that could never be visited by spacecraft because of the intense heat radiating from the nearby solar surface. In a paper published today in the journal Science, researchers from several institutions – including the Solar and … more

Stretchable, transparent graphene-metal nanowire electrode
Ulsan, South Korea (SPX) Jun 04, 2013 – A hybrid transparent and stretchable electrode could open the new way for flexible displays, solar cells, and even electronic devices fitted on a curvature substrate such as soft eye contact lenses, by the UNIST(Ulsan National Institute of Science and Technology) research team. Transparent electrodes are in and of themselves nothing all that new – they have been widely used in things like … more
