Scientists have managed to trap beams of infrared light in a lattice of specially engineered atoms that's just 42 nanometers thick. That's around 2,000x thinner than a human hair or an even thinner sliver of a standard sheet of paper. The impressive feat, led by a team from the University of Warsaw in Poland, promises significant implications for light-based electronics , as technology components continue to become smaller and more precise. It's also a notable advance in the study of infrared
