From reading the abstract, this is doing the same as reported in a 2014 paper in Phys. Rev. B by many of the same authors [1], but with a different material (K3C60). In [1] they propose the hypothesis (hence "possible" in the title here) that: "the light establishes a transient superconducting state over only a fraction of the solid, with a lifetime of a few picoseconds" While certainly an interesting piece of solid-state physics, I don't think it brings us much (if any) closer to useful-for-transporting-electricity room-temperature superconductors. (It could certainly be useful for other things though.) [1] http://journals.aps.org/prb/abstract/10.1103/PhysRevB.89.184516 http://journals.aps.org/prb/abstract/10.1103/PhysRevB.89.184... Edit: this group also had a similar paper in Science in 2011 that might also be of interest: http://science.sciencemag.org/content/331/6014/189 http://science.sciencemag.org/content/331/6014/189
