| Clues to growth of colossus in Coma cluster of galaxies Posted: 19 Sep 2013 11:21 AM PDT Astronomers have discovered enormous arms of hot gas in the Coma cluster of galaxies. These features, which span at least half a million light years, provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the Universe held together by gravity.  |
| In water as in love, likes can attract Posted: 19 Sep 2013 06:37 AM PDT Researchers have shown that, contrary to the scientific axiom that only opposite charges attract, when hydrated in water, positively charged ions can pair up with one another.  |
| Are both the economic development and spatial impacts of High Speed Rail worth it? Posted: 19 Sep 2013 05:56 AM PDT With the High Speed Rail project being debated widely in both the U.K. parliament and the media, it is important to review and understand the economic impacts of HSR. Scientists now make the link between past studies on HSR economic impacts and future predictions, while evaluating both the positive and negative effects of HSR on Planning and Urban form transformations.  |
| Posted: 19 Sep 2013 05:54 AM PDT It is quite simple for pianists like the Chinese virtuoso Lang Lang: Whether it is music by Mozart, Rachmaninoff or Tchaikovsky, they can play the piano quickly. Researchers transferred this skill in piano playing to text entry by developing a computational approach that assigns words and letters to notes and chords. In this way experienced as well as hobby-pianists can enter text as fast professional typists.  |
| Glass or plastic? Container's material properties affect the viscosity of water at the nanoscale Posted: 19 Sep 2013 05:52 AM PDT Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially other fluids, whether the container is made of glass or plastic does make a significant difference.  |
