This is SCIENCE FRIDAY. I'm Ira Flatow. We're here at the Wisconsin Science Festival at the Institute for Discovery in Madison and talking about a trip to America's dairy land, of course. Inevitably you're going to talk about food and fermentation. In the form of Wisconsin, it's famous for fermentation, one of the oldest ways of preserving food. It's also a way to get really unique flavors.
This is SCIENCE FRIDAY, I'm Ira Flatow. We're broadcasting from the Wisconsin Institutes for Discovery in Madison, home this week of the Wisconsin Science Festival. Astronomers and astrophysicists have traditionally, for centuries, looked upwards to the sky to learn more about the universe. We've launched telescopes into space. We have sent probes beyond our solar system to study dark matter, colliding galaxies, how the planets formed.
We've been talking about the Stone Age but now we're living in what some scientists are calling the anthropocene. Maybe you've never heard of that word.
