They managed to get carbon to superconduct at tempertures higher than liquid nitrogen (with potential for even higher temperatures), is potentially cheaper than other types of superconductivity and could be easier to work with then the copper-oxide ceramics.
If things keep advancing like they are, it won't be too many years until we get superconductive wire available to the general public. I would love to be able to run down to radio shack and pick up a spool of superconducting wire for all sorts of home projects.

Well, slight correction. Liquid nitrogen is liquid at, what, about -70F? The story cites the experiment as achieving superconductivity at -243F, higher than liquid *helium* (and thus a hell of a lot cheaper to reproduce), but still well below liquid nitrogen. And it isn't like you can get a spool of this stuff to superconduct; it has to be immersed in two different super-cooled chemicals to remain in that state.
This isn't even the highest-temperature superconductivity ever produced - but it does appear to be the cheapest, and that's a major advance in and of itself.
Sure does. And this phenomenon is not just confined to Slashdot either. The links to the Yahoo! articles also show that two very similar articles were published on this very topic no more than sixteen minutes apart (2:03PM ET and 2:19PM ET). The only difference in the articles was the source - the earlier article's source was Associated Press whereas the later article's source was Reuters.

Actually, the boiling point of nitrogen is -196C (about 70 K), well below the temperature required for this superconductivity. Ya gotta love when articles use degrees Fahrenheit as the units in a scientific article. It never fails to confuse somebody.

... it's about 117 Kelvin.
Relatively inexpensive, and getting warmer all the time. I'm looking forward to the day...
It may look like I'm doing nothing, but I'm actively waiting for my problems to go away.

Looks like they can also be used to cause slashdot writers to post the same story twice in one week.
