Robyn Sue Fisher's ice cream shop, Smitten, in San Francisco's Hayes Valley, may at moments resemble a high school chemistry lab, but that's because Fisher uses liquid nitrogen to freeze her product.

The new bird flu in China has come with a long list of questions.

Are the 82 cases reported so far just the tip of a larger outbreak? Why does the virus cause mild symptoms in some people and severe pneumonia in others?

In his cover story for the April 29 issue of The New Republic, "The Hell of American Day Care," Jonathan Cohn writes that "trusting your child with someone else is one of the hardest things a parent has to do — and in the U.S., it's harder still, because American day care is a mess. And about 40 percent of children under 5 spend at least part of their week in the care of somebody other than a parent."

Kim Richey performs live on Mountain Stage.
Brian Blauser Mountain Stage

Singer-songwriter Kim Richey makes her fourth appearance on Mountain Stage, recorded live at the Culture Center Theater in Charleston, W.Va. Richey first emerged in the early 1990s as part of the growing alt-country movement — and, as such, remained difficult to classify. Nevertheless, Richey's music didn't go unnoticed in Nashville: Many of her songs ended up recorded by mainstream heavyweights such as Trisha Yearwood and Brooks & Dunn.
