911½ñÈÕºÚÁÏ

In the latest 911½ñÈÕºÚÁÏ Podcast, we visit the Royal Society Summer Science Exhibition and look into the science behind Back to the Future.

Professor Alan Heavens gave a talk on time travel alongside a special screening to mark the film’s 30^th anniversary. We asked him what period of history he would like to travel to.

At the Royal Society, 911½ñÈÕºÚÁÏ researchers showed us their exhibits demonstrating 'audio zoom' technology and advanced techniques for studying individual cells in isolation.

The podcast is presented by Gareth Mitchell, a lecturer on 911½ñÈÕºÚÁÏ's Science Communication MSc course and the presenter of , with contributions from our roaming reporters from the Research Communications group.
