University of Rochester (whose name, as custom dictates, must always be pronounced in your best Jack Benny voice) researchers have made a pioneering advancement in "optical buffering", a technique that leverages wave-particle duality (and a cell of cesium gas) to achieve incredibly high signal-to-noise ratios at mind-crogglingly low light levels. As in: recreating an entire image (in this case, the "UR" shown above) using only a "single" photon.
In addition to being magnificently weird, this represents yet another significant step towards the holy grail of calculation (the apex of abaci?), quantum computing. And, of more immediate significance, it allowed me to make the obligatory "I'M IN UR..." reference, which I hereby dedicate to matrushkaka.
