Have there been any recent breakthroughs in superconductor research?

Question

I recently skimmed an article on superconductors; I think it said a major breakthrough had been made, but I didn't note the date and have forgotten the link.

Answer 1

How old is the article. There was a major breakthrough in the 80's with high temperature superconductores (> 77 K), but progress on practical applications (requires increasing flexibility) have been incremental since then.
