Researchers at the University of St Andrews have made a surprise discovery using light beams that can travel around corners.


The academics have developed the concept of moving particles within light beams that follow curves rather than go along straight lines building on their work in the area of optical manipulation.


Professor Kishan Dholakia of the School of Physics and Astronomy commented, "Physics holds many surprises; our understanding of how light moves and behaves is challenged by such beams and it is exciting to see them move into the interdisciplinary arena - light has thrown us a curve ball!” source...
