The First Room-Temperature Superconductor Has Finally Been Found (sciencenews.org) 102
Dias and colleagues formed the superconductor by squeezing carbon, hydrogen and sulfur between the tips of two diamonds and hitting the material with laser light to induce chemical reactions. At a pressure about 2.6 million times that of Earth's atmosphere, and temperatures below about 15 degrees C, the electrical resistance vanished. That alone wasn't enough to convince Dias. "I didn't believe it the first time," he says. So the team studied additional samples of the material and investigated its magnetic properties.
Superconductors and magnetic fields are known to clash -- strong magnetic fields inhibit superconductivity. Sure enough, when the material was placed in a magnetic field, lower temperatures were needed to make it superconducting. The team also applied an oscillating magnetic field to the material, and showed that, when the material became a superconductor, it expelled that magnetic field from its interior, another sign of superconductivity. The scientists were not able to determine the exact composition of the material or how its atoms are arranged, making it difficult to explain how it can be superconducting at such relatively high temperatures. Future work will focus on describing the material more completely, Dias says.

Do you rejoice when you get an email about an upgrade of the vending machines in the company cafeteria, or do you worry about the new machines not carrying the kind of soft drinks or candy bars you're used to? That's basically how a typical office worker feels about computers. Spend a week working helpdesk and you'll understand that very very clearly.
That's why when you manage a large pool of workstations you want the bare minimum that users need to do their work, and why you want that bare minimum to be set in stone. Otherwise you're just annoying users and adding more support tickets to your queue.
I could not agree more.

Submission + - Lawsuit over quarter horse's clone may redefine animal breeding (latimes.com)
Texas horse breeder Jason Abraham and veterinarian Gregg Veneklasen sued the American Quarter Horse Assn., claiming that Lynx Melody Too should be allowed to register as an official quarter horse. A Texas jury decided in their favor in 2013, but a three-judge panel of the U.S. 5th Circuit Court of Appeals reversed that ruling in January, saying there was "insufficient" evidence of wrongdoing by the association.
The Jockey Club, which registers thoroughbreds, has banned them from racing. But clones are allowed in other competitions, such as dressage and rodeo. There is little uniformity among other animal groups. The American Kennel Club has banned clones; the Cat Fanciers' Assn. has no policy yet since no one has tried to register a cloned cat.
