In June 2017, physicists achieved ‘liquid light’ at room temperature for the first time ever, making this strange form of matter more accessible than ever. This matter is both a superfluid, which has zero friction and viscosity, and a kind of Bose-Einstein condensate - sometimes described as the fifth state of matter – and it allows light to actually flow

Researchers from Montreal’s National Institute of Scientific Research (INRS) just published a study in Optica detailing a new approach to invisibility cloaking. Their device, called a spectral invisibility cloak, is the first to manipulate the color (or frequency) of the light waves that interact with an object, rendering it invisible. “Our work represents a breakthrough in the quest
