This ten-minute recording was made for a local radio show with a strap line that 'science has a use after school'. Audio podcasts, of which this is one, replace easily-missed radio shows and keep us informed. Universities also create podcasts, and just some teachers do too, gaining the unusual advantage that a podcast easily gets into a student's music player.
