Ripped from the pages of a sci-fi novel, physicists have crafted a wormhole that tunnels a magnetic field through space. "This device can transmit the magnetic field from one point in space to another point, through a path that is magnetically invisible," said study co-author Jordi Prat-Camps, a doctoral candidate in physics at the Autonomous University of Barcelona in Spain. "From a magnetic point of view, this device acts like a wormhole, as if the magnetic field was transferred through an extra special dimension."
The idea of a wormhole comes from Albert Einstein's theories. In 1935, Einstein and colleague Nathan Rosen realized that the general theory of relativity allowed for the existence of bridges that could link two different points in space-time. Theoretically these Einstein-Rosen bridges, or wormholes, could allow something to tunnel instantly between great distances (though the tunnels in this theory are extremely tiny, so ordinarily wouldn't fit a space traveler). So far, no one has found evidence that space-time wormholes actually exist
The new wormhole isn't a space-time wormhole per se, but is instead a realization of a futuristic "invisibility cloak" first proposed in 2007 in the journal Physical Review Letters. This type of wormhole would hide electromagnetic waves from view from the outside. The trouble was, to make the method work for light required materials that are extremely impractical and difficult to work with, Prat said.
So the team designed a three-layer object, consisting of two concentric spheres with an interior spiral-cylinder. The interior layer essentially transmitted a magnetic field from one end to the other, while the other two layers acted to conceal the field's existence.

The article is misleading. They shouldn't be drawing a parallel between this clocking mechanism and wormholes. Wormhole are supposed to fold space-time. This does no such thing. This is merely a way to channel a magnetic field along a cloaked path.
Don't get me wrong, I find this to be a fascinating new discovery that the Military-Industrial complex will use against us, but no quantum mechanics here.

Then why title the article "Wormhole created in lab" ? No way what I read is this a wormhole.....very misleading.A wormhole is a theoretical occurrence in certain models that link 2 points in the space/time fabric together. And not much to do with cloaking or magnetism.
