In biology, defects are generally bad. But in materials science, defects can be intentionally tuned to give materials useful new properties. Today, atomic-scale defects are carefully introduced during ...

Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...
