This is a surprising and exciting progress. But I think how to use the long lived photon to the chemistry, like to explore solvated electrons. How about the energy of the photon?
Exactly how do you detect a photon many times without destroying it? Or without reducing its energy? This question is not addressed in the story, which is taken on faith from the French scientists' claim.
