If you’re at work, I hope you have headphones; if you don’t, check in once you get home. Here are a couple of audio recordings of good science.

• John Rennie speaks out on stem cells on an Australian program, the Science Show.
• I reviewed her new book a while ago, and now you can hear Christiane Nüsslein-Volhard lecture on basic developmental biology. She has a very nice light German accent that makes it especially pleasant to listen to, I think.
