Annoying Sounds, Washer Lint, and Pushing Objects With Light

 

The Science Magazine podcast called Annoying Sounds, Washer Lint, and Pushing Objects with Light answers some pretty interesting questions about lint, light and irritating sounds.

Why is the sound of fingernails on a chalkboard so painful? How can light be used to move an object? And is washer lint dangerous to ocean ecosystems? Science's Online News Editor David Grimm chats about these stories and more with Science's Kerry Klein. Listen to podcast.
