Light is all around us and it is being used in incredible ways in medicine and biology. Light can be used to image microscopic objects such as cells, bacteria and small organisms. In healthcare, light can be used to treat a number of medical conditions, such as certain types of cancer. Light is also a useful research tool. Laser beams can be used to trap and move tiny objects and to punch holes in them.

How do we see the unseeable? How are scientists shining a light on cancer? How can laser beams be used as tweezers and scissors?

Discover this and more through our resources, interactive activities and events. You'll be amazed how light is changing our lives!

Project Overview

‘Seeing life through a new light’ is a science outreach project from the School of Physics and Astronomy, University of St Andrews. The aim is to enthuse and excite the general public about light and its use in medical and biological applications. Interactive shows, lectures and workshops are being delivered throughout Fife, Scotland and the UK to school, family and adult audiences to show how light is changing our life.

Themes include imaging techniques for studies of cells and tissue, optical healthcare treatment techniques and the use of light as a tool in cutting-edge research.

The project is funded by the Engineering and Physics Sciences Research Council (EPSRC) through a Partnership for Public Engagement (PPE) Award.
