If I am reading the article correctly, it is implying that this research may eventually tell scientists how high-temperature superconductors work?
I hope that is what it really says. I don't know how hopeful that is if that is what it is really saying.

In this article they are talking about effective mass, which isn't quite the same as "real" mass.

I think the only way for an electron to gain 'real' mass is to accelerate like a bat out of hell and get to within a hair's breath of c.

That's relativistic mass. 😉
