Is it April yet?

There's a 1 April feel about the following story:

Japanese researchers have been immersing iron-based compounds in hot alcoholic beverages such as red wine, sake and shochu to induce superconductivity.

Scientists from the National Institute for Materials Science, Japan, found that immersing pellets of an iron-based compound in heated alcoholic beverages for 24 hours greatly increase their superconducting ability.

But as it appears in the journal Superconductor Science and Technology, published on 7 March, it appears not to be a joke.

Red wine worked best, by the way...
