St Andrews science in national spotlight
Imagine a beam of light that can trap and manipulate microscopic objects like the tractor beam in Star Trek. Science fiction? No, science fact, thanks to the 'optical tweezers' used at the School of Physics and Astronomy at the University of St Andrews.

Lasers put tiny objects in a spin
University of St Andrews scientists have designed a novel way of spinning the most delicate microscopic objects - from a hamster chromosome to a glass bead - without damaging them.
Government grant for high-tech laser research
A range of infra-red lasers with commercial implications for gas leak detection and medicine are to be developed by University of St Andrews scientists.
