Space travel, Aids, women in physics

In this week’s podcast: We mark World Aids Day with a chat to Sir Nick Partridge, chief executive of the Terrence Higgins Trust, we discuss the future of space flight with Kevin Fong, from University College London – an expert on space medicine, and we hear from Science Magazine about how women can overcome sexist stereotypes in physics courses.

Presented by Clive Cookson with Andrew Jack.
