Fleeting fluctuations in superconductivity disappear close to transition temperature
(PhysOrg.com) -- As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists at Johns Hopkins University and the U.S. Department of Energy's Brookhaven National Laboratory have measured fluctuations in superconductivity across a wide range of temperatures using terahertz spectroscopy. Their technique allows them to see fluctuations lasting mere billionths of a billionth of a second, and reveals that these fleeting fluctuations disappear 10-15 Kelvin (K) above the transition temperature (Tc) at which superconductivity sets in.

(PhysOrg.com) -- Nebulae are enormous clouds of dust and gas occupying the space between the stars. Some have pretty names to match their good looks, for example the Rose nebula, while others have much more utilitarian names.

Satellites locate seized Italian oil tanker
(PhysOrg.com) -- The Cosmo-SkyMed satellites, operated by the Italian space agency, have acquired the first images of the Italian oil tanker Savina Caylyn since it was hijacked earlier this week by Somali pirates in the Indian Ocean.

Roses are red, but not 'green'
For many Americans, giving your significant other a dozen sweet-smelling roses is the ultimate symbol of Valentine's Day affection, but it might not be the best expression of love for your planet.

Strong quake jolts Chile; magnitude 6.8
(AP) -- A magnitude-6.8 earthquake struck central Chile Friday, centered in almost exactly the same spot where last year's magnitude-8.8 quake spawned a tsunami and devastated coastal communities.

Europe set for landmark launch with robot freighter
A robot freighter is poised to blast into the skies on Tuesday in the heftiest liftoff in Europe's space programme that will also bring its tally of launches to a historic 200.

Study finds massive flux of gas, in addition to liquid oil, at BP well blowout in Gulf
A new University of Georgia study that is the first to examine comprehensively the magnitude of hydrocarbon gases released during the Deepwater Horizon Gulf of Mexico oil discharge has found that up to 500,000 tons of gaseous hydrocarbons were emitted into the deep ocean. The authors conclude that such a large gas discharge—which generated concentrations 75,000 times the norm—could result in small-scale zones of "extensive and persistent depletion of oxygen" as microbial processes degrade the gaseous hydrocarbons.
