Sting debuts free app, pays tribute to Steve Jobs (AP)

NEW YORK ? Sting has launched an app for the iPad, and he's not charging for it.

The singer introduced STING 25 in honor of his 25-year solo career at the Apple Store in New York's Upper West Side on Monday. The "Appumentary" is a digital documentary of Sting's career. It features over four hours of music videos, concert footage, interviews and more.

Sting says he's releasing it for free "because we don't know how much it's worth."

The app also has video from Sting's 60th birthday party-concert last month at New York's Beacon Theatre, which featured performances with Bruce Springsteen, Stevie Wonder and Lady Gaga.

At Monday's event, Sting performed the song "Fragile," dedicating it to Apple co-founder Steve Jobs and saying, "In some way he's created our future."

Graham: military last guard against nuclear threat (AP)

WASHINGTON ? Sen. Lindsay Graham is siding with a Republican presidential candidate who's calling for military action if all else fails to stop Iran from developing a nuclear weapon.

The South Carolina Republican says he supports "totally, absolutely, without any doubt" former Massachusetts Gov. Mitt Romney's call during a Saturday debate for the military last-resort option to keep nuclear weapons out of Iran.

Graham says in a television interview, quote, "If they develop nuclear weapons, the whole region is going to want a nuclear weapon. If you open Pandora's box, if you attack Iran if they get a nuclear weapon, you empty Pandora's box."

Graham also said it's important to "neuter this regime" by destroying its military and persuading Iranians to demand a regime change.

Graham appeared on CBS' "Face the Nation."

Superconductor may hide long-sought secret

Material could demonstrate existence of a type of particle proposed 70 years ago

Web edition : Monday, November 14th, 2011

A new kind of superconductor can?t make up its mind about how to conduct electricity. Current passes through its interior without any resistance, as in a typical superconductor. But its skin behaves like a metal, conducting electricity but with some resistance.

This split personality, described in an upcoming Physical Review Letters, could be the handiwork of something strange hiding on the surface ? a two-dimensional entity behaving like a Majorana fermion. First proposed more than 70 years ago, a Majorana fermion is a theoretical type of particle that is its own antiparticle. Electrons and quarks and other particles of matter all have twin antimatter partners.

Some theorists who suspect that neutrinos are their own antiparticles would be excited to find evidence that anything can act like a Majorana fermion, even the surface of the superconductor in the new study. Others hope that such particles could be useful for storing information in new kinds of computers.

?This is great,? says Robert Cava, a chemist at Princeton University who wasn?t involved with the study. ?Hopefully it will get people excited about this material.?

Cava and colleagues were the first to create that material, made of copper, bismuth and selenium layered like lasagna. They showed that it?s a superconductor at temperatures within a few degrees of absolute zero. But until now, no one had conclusively proven that this superconductivity is any different from the run-of-the-mill variety discovered in mercury a century ago.

To probe the material, Yoichi Ando of Osaka University and colleagues in Japan injected current into it using a gold wire. This excited electrons at the surface, creating ripples of energy. Conventional superconductors have a dead spot in their surfaces that prevents low-energy, slow-wobbling ripples from forming. But a close look at this material revealed a sea of waves bouncing up and down both quickly and slowly.

Ando says that this pattern of ripples is ?unambiguous evidence? of a type of superconductivity never seen before: topological superconductivity, in which electrons become waves molded into a complex shape that resembles the outside of a doughnut. These waves, says Ando, seem to be behaving like exotic two-dimensional particles at the surface of the material ? specifically, Majorana fermions.

?This is the best evidence so far for Majorana fermions in a solid material,? says Taylor Hughes, a theoretical physicist at the University of Illinois at Urbana-Champaign. Still, the new experiment didn?t actually reveal the flat fermions themselves ? only their supposed influence. No one has yet figured out how to directly detect them in solids. So it?s probably going to take many sources of indirect evidence to make the case that Majorana fermions actually exist in this material, says Hughes.

One way to test the idea would be to use magnetic fields to create swirling vortices on the material?s surface. These vortices should be able to trap a Majorana fermion and reveal it to be located not in a single spot, but stretched between two points like a rubber band.

Being spread out in this way could make Majorana fermions useful for quantum computers. These devices store information in the quantum states of particles, which tend to be fragile. But Majorana fermions can be disturbed only by attacking both of their end points simultaneously, giving them a hardiness that could help future computers solve problems out of the reach of today?s technology, mistake-free.

Stolen wedding album returned 17 years later (Reuters)

LONDON (Reuters) ? A wedding album which went missing when a caravan was stolen in Northern Ireland 17 years ago has mysteriously reappeared at the home of its owners.

Nigel and Gillian Stewart had long given up hope of seeing their wedding photographs which were inside the caravan when it was stolen, but Tuesday the album was left at the gate to their home in a plastic bag, the BBC reported.

"I thought I was seeing things," the BBC quoted Gillian as saying this week. "I was absolutely stunned. Speechless."

The couple recently celebrated their 25th wedding anniversary and the album's reappearance at their home in Gilford, County Down, has been a revelation for their children.

"It's lovely for the children -- they only know their dad with grey hair," Gillian joked.

She said she was extremely grateful to whomever gave the photographs back and wonders all over again who it was that stole the caravan, but added that she bore no grudges.

"You needn't be a bit afraid to come forward to me, because I bear no grudges. The past is the past, the future's the future," she said.

"I would just love whoever it was to come forward, so I could thank them in person."

Google invitations go out: Music store in our midst? (Digital Trends)

google music eventGoogle has begun sending out invitations with a Spinal Tap reference that lead us to believe there is a Google Music event scheduled for next week. While the notice says little besides that the announcement is the 16 and will be broadcast on the Android YouTube channel, all signs point toward a music store accompanying its recently launched streaming and storage service.

A report last month speculated that Music Beta would soon get an MP3 store to supplement its current catalog and users? own music collections. While Music Beta received plenty of enthusiasm prior to its launch, attention has somewhat worn thin as consumers have realized the library options are less than infinite. Without a music content store to make purchases from, Music Beta subscribers are forced to find their songs elsewhere, likely via Amazon or iTunes?both of which offer their own locker and player services.

It would be a significant coup for Google to open up shop, especially for its mobile platform. If Google could get Android users to defer to its own offerings in lieu of iTunes, that?s a victory in and of itself. Google Music is also supposed to integrate with Google+ soon, which might be able to boost traffic for the social network and the streaming service at the same time. Certainly, weaving these applications together is part of Google?s roadmap, but we can?t help feeling like users are getting a little impatient while they wait for the G+ payoff.

Of course, the holdup has been Google?s inability to find an agreement with major recording labels, something it?s still working on. The risk of launching Music Beta when it did had elements of its Google TV debacle: without rights to the content, you?re selling an empty product. But if Google was able to negotiate with record labels (or at least two or three of the big four), then a Google+ integrated service would definitely prompt some renewed interest. ?
