I think “loses” lends itself to clickbait.

It’s either 0 or massful.

“Loses”, to my eye, implied a continuous ability to remove mass, and led me to wonder if one could achieve negative masses with the experiment’s technique.

But I’ll save you the click: in one direction it’s massless (traveling at the speed of light), and in the other direction it has mass.

Saying "particle" instead of "quasiparticle" is also a little click-baity. Although, admittedly, the general public probably has no idea what a quasiparticle is. Not that the article does a very good job of explaining it.
