Great stuff, still not suitable for cables, though

The International Space Station (ISS) will soon host the coldest spot in the entire universe, if everything goes according to plan.
This August, NASA plans to launch to the ISS an experiment that will freeze atoms to only one billionth of a degree above absolute zero -- more than 100 million times colder than the far reaches of deep space, agency officials said.
The instrument suite, which is about the size of an ice chest, is called the Cold Atom Laboratory (CAL). It consists of lasers, a vacuum chamber and an electromagnetic “knife” that together will slow down gas particles until they are almost motionless.

Attempts to create Bose-Einstein condensates on Earth have been only partially successful to date. Because everything on Earth is subject to the pull of gravity, atoms and molecules tend to move toward the ground. This means the effects can only be seen for fractions of a second. In space, where the ISS is in perpetual freefall, CAL could preserve these structures for 5 to 10 seconds, NASA officials said. (Future versions of CAL may be able to hold on for hundreds of seconds, if technology improves as expected, officials added.)
