Well, I’ve listened to the first New Scientist Podcast and, frankly, it was rather disappointing. 🙁 A bit too American and glitzy for me and it came as something of a culture shock thinking of that as coming from what has, to me, always seemed a rather more British publication.
A much nicer science podcast (and a lot longer too, about an hour instead of 10 minutes) is the excellent Australian Radio National program The Science Show presented by Robyn Williams (no, not Robin) which isn’t afraid to get into the nitty gritty of a story and also has a great sense of humour. There’s also the fact that Robyn has been doing this since the 70’s, so there are nice touches like them playing extracts from him interviewing Fred Hoyle in 1978 when discussing (in 2005) a new biography of him.
