I'm a fan of the The Naked Scientists podcast with Chris Smith. This is a fun, English podcast with features such as 'kitchen science' experiments for kids to try at home and quizzes for listeners.
For weekly podcasts on Science with a more serious tone, my new favorite is Chris Smith's Nature podcast. Many of the topics are related and the sponsers are the same. The difference is more in-depth interviews with scientists on their latest discoveries.
