 | We Americans take the electric current behind our power buttons for granted, and assume the juice will be there when we need it. Will it? DHS S&T is funding a superconductor technology that will make sure it is. ...> Full Article |
If you are curious about the potential of quantum computing, you will want to keep your eye on "Harnessing Quantum Physics." This is one of many panel discussions coming your way as part of the Quantum to Cosmos Festival, running on-site, online and on TV from October 15-25, 2009.

Despite their popularity in the science fiction genre, there is much to be learned about black holes. In a paper published in the August 20 issue of Physical Review Letters, the flagship journal of the American Physical Society, Dartmouth researchers propose a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts.

 | University of Utah mathematicians developed a new cloaking method, and it's unlikely to lead to invisibility cloaks like those used by Harry Potter or Romulan spaceships in "Star Trek." Instead, the new method someday might shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures from tsunamis. ...> Full Article |
 | A special three-day symposium focusing on the neutrino, a strange subatomic particle that could help answer some of the universe's most compelling questions, is scheduled for Aug. 16-18 at the 238th National Meeting of the American Chemical Society in Washington, D.C. ...> Full Article |
 | NIST physicists have improved an experimental atomic clock based on ytterbium atoms, which now about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock. ...> Full Article |

 | Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically ?? but has up to five levels of energy instead of the usual two. The findings are published in the Aug. 7 issue of Science. ...> Full Article |
 | Scientists have measured the largest effect of the "weak interaction" -- one of the four fundamental forces of nature -- ever observed in an atom. ...> Full Article |
CERN 's Large Hadron Collider will initially run at an energy of 3.5 TeV per beam when it starts up in November this year. This news comes after all tests on the machine's high-current electrical connections were completed last week, indicating that no further repairs are necessary for safe running.

In the classic fairy tale, "The Emperor's New Clothes," Hans Christian Andersen uses the eyes of a child to challenge conventional wisdom and help others to see more clearly. In similar fashion, researchers at the University of Illinois have now revealed the naked truth about a classic bell-shaped curve used to describe the motion of a liquid as it diffuses through another material.

A well-established physical law describes the transfer of heat between two objects, but some physicists have long predicted that the law should break down when the objects are very close together. Scientists had never been able to confirm, or measure, this breakdown in practice. For the first time, however, MIT researchers have achieved this feat, and determined that the heat transfer can be 1,000 times greater than the law predicts.
