For our end of term science trip, we take the podcast on the road to London's Royal Institution.
In the Faraday lecture theatre, we speak to Chris Bishop who is giving this year's Christmas lectures. The theme this year is making the ultimate computer.
James Randerson is the Guardian's only science correspondent who remembered to bring his permission slip allowing him to be unchained from his desk.
We also visit the Science Museum's new exhibition on GM technology - Future Foods. Tim Lang, professor of food technology at London's City University, tells us why the GM industry in the US is at risk. Hear more on the exhibition in our Science Weekly Extra podcast.
