This week, the studio is invaded by a Dalek…. well not really, it’s actually Nicholas Briggs, the man behind the voice of the Daleks on Doctor Who. He talks to us about the technology used to generate the voices of the Daleks and how they are operated. Our final Back to Black profile looks at neurosurgeon Ben Carson and our STEM Ambassador of the Week is Dr. Hefin Jones from the School of Biosciences at Cardiff University. Finally, in our regular Astronomy feature with Chris North and Hugh Lang from the School of Physics & Astronomy at Cardiff University, Chris talks to Ed Gomez about the possibility of alien life on other planets and Hugh gives us a preview of the night sky in November.
