JPL Researchers Unveil Superconductor-Based Light Detector
Source: NASA/JPL Posted: 10/26/03 A new and improved way to measure light has been unveiled by physicists at NASA’s JPL.The technology exploits the strange but predictable characteristics of superconductivity, and has a number of properties that should lead to uses in a variety of fields, from medicine to astrophysics.
The 2003 Nobel Prize in Physics
Source: Nobel Posted: 10/22/03 The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2003 "for pioneering contributions to the theory of superconductors and superfluids" jointly to three scientists, Abriskosov, Ginzburg and Leggett.
Researchers Find That Superman’s Teeth Can Superconduct
Source: UWarwick Posted: 10/14/03 Researchers at the University of Warwick have found that phosphorus, an element commonly found in teeth, can act as a “superconductor” – but you would have to have the strength of Superman to clench your teeth hard enough for it to work.
Saturn-Bound Spacecraft Tests Einstein's Theory
Source: NASA/JPL Posted: 10/13/03 An experiment by Italian scientists using data from NASA's Cassini spacecraft, currently en route to Saturn, confirms Einstein's theory of general relativity with a precision that is 50 times greater than previous measurements.
For quantum confinement, size matters, but so does shape
Source: WUSTL Posted: 10/13/03 Size matters, but so does shape, at least in the world of semiconducting nanocrystals, report chemists at Washington University in St. Louis. Their findings, published in the August 2003 issue of Nature Materials, demonstrate experimentally that the shape of a semiconductor nanocrystal can affect its electronic and optical properties.
NASA research propels development of new glass

World's biggest gamma radiation telescope begins operation
Source: INFN Posted: 10/7/03 On October 10th the Magic Telescope (Major Atmospheric Gamma Imaging Cherenkov telescope) will be inaugurated. With his 17-meter-diameter-mirror and 240 square meters surface, it’s the largest telescope in the world dedicated to ‘gamma astronomy’, that is devoted to the detection of gamma rays.
'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
