Science Friday: DNA Testing

We’re very excited to bring you this weekly feature – Science Friday, a science talk show produced by NPR. Each week, a new video takes on a different on science topic, in an effort to bring an educated, balanced discussion to bear on the scientific issues at hand.

You may remember that we started this feature more than a year ago – but technical difficulties kept us from making it a regular appearance. Thanks to the fine folks at SciFri, however- I think we’ve got it figured out. Hopefully, we’ll be bringing you the science-y goodness every Friday from now on.

This week we follow two high school students from New York as they perform a DNA test on foods to see just what ingredients are in our everyday meals. They review if goat milk really comes from goats, the origin of caviar, and what exactly goes into New York City hot dogs.
