For the last couple of months, The Guardian has been producing a weekly science podcast, in which the Guardian science team discusses various topics and interviews experts on the issues of the week. Some examples are
An interview with David Bodanis, who recently won the Aventis science book prize for his book How Electricity Switched on the Modern World (Incidentally, it is worth either listening to or reading about what he did with his prize money, which reminded me of what my friend Paul did with his). (This week's episode, May 22)
A discussion with Vivienne Parry (also nominated for the Aventis prize) about psychedelic drugs (May 1)
The story of the battle to keep Hooke's papers in Britain (April 3).
Whatever one might think about the general trend of science coverage in The Guardian, I think this is a pretty fun idea that is likely to catch on in other places. It's also interesting to see how the lines between various types of media are becoming blurred as new technologies become easier to use.
