This article has a number of amazing things, including some incredible engineering feats that are tossed out as just things that had to be done to do the really cool things.

"For their experiment, the scientists manufactured periodic stacks made of alternating layers of 57Fe and non-resonant 56Fe, the most commonly occurring isotope of iron, each less than two nanometres thick."

>From another section: "Thanks to this apparatus, the scientists managed to measure the two new resonances, which are separated by only 37.3 nano-electronvolts and which can be attributed to the creation of polaritons."
