What are the origins of slow-light research and where is the field heading? Nature Photonics spoke to Robert Boyd to find out. Actually, ideas about slow and fast light go back at least 170 years.

New research reveals light can behave as a supersolid, paving the way for advancements in quantum computing and optical ...

A series of new animations by a NASA scientist show just how zippy - and also torturously slow - the speed of light can be. Light-speed is the fastest that any material object can travel through ...
