  A recent article in "The New York Times" claimed that IBM has recently
made breakthroughs in the new oxide-type superconductors yielding huge
current densities.  I can't remember the exact figure, but I think it 
was in the hundereds of thousands of amps.  The article commented that
superconductors with small current densities weren't extremely useful
and that the IBM development was a major breakthrough.

  In fact, I've been kind of surprised at all the attention that
superconductor research has been getting in the "Times".  There have
been at least 5 front-page articles about superconductors in the past
3 months.  The most recent article (last Tuesday, I think) claimed
that new materials superconduct at dry ice temperatures and that these
same materials exhibit small amounts of superconductivity at room
temperature!
