How do you turn facial expressions into music?

A microscopic water flea that could help monitor our waterways for pollution, turning both quantum circuits and facial expressions into music, and how animals use vibrations to sense the world around them.

These are some of the cutting edge research projects being presented at the Royal Society Summer Science Exhibition in London.

Victoria Gill is joined by Caroline Steel for a special episode from the exhibition, meeting the researchers showcasing their work and getting hands on with the science on display.

We speak to Daisy Shearer from the National Quantum Computing Centre, PhD student Clelia Altomonte from King's College London, Dr Beth Mortimer from the University of Oxford who leads its Animal Vibration Lab (the exhibit was developed with Dr Alice Morrell and Eleanor McKelvey), Dr Katie Reilly from the University of Birmingham, the CEO of the charity Drake Music, Sally Currie, and the designer of the PhotoSYNTH accessible musical instrument, Zenon Olenski.
