| Solved: Mystery of the nanoscale crop circles Posted: 02 Mar 2012 07:18 AM PST A useful alloy of gold and silicon, called a eutectic, melts at a far lower temperature than either of its components. Until now, however, its odd behavior on the nanoscale has confounded researchers. By analyzing peculiar "nanoscale crop circles" formed from ultra-thin layers of gold on silicon, scientists have discovered the eutectic alloy's unique properties, including its special promise for engineering and processing nanoscale materials. |
| Pasta-shaped radio waves beamed across Venice Posted: 02 Mar 2012 05:30 AM PST A group of Italian and Swedish researchers appears to have solved the problem of radio congestion by cleverly twisting radio waves into the shape of fusilli pasta, allowing a potentially infinite number of channels to be broadcast and received. |
