For the rest of the hour, we're going to talk about meteorites. They are more than just a chunk of rock. They can be a time capsule, or ancient secrets of our solar system may be locked up in its core. And it turns out - I didn't know this - that one of the largest meteorite collections, the largest one, the largest collection held by any university is just up the road from us in Tempe. And joining us now to talk about the collection is Meenakshi Wadhwa.

(SOUNDBITE OF THEME MUSIC)
SIMON: All that cheering. Florida Gulf Coast Eagles got eaten by the Gators yesterday, but the Cardinals are still flying high. Louisville, Florida, Michigan and Duke move on to men's college basketball Elite 8; and baseball season opens tomorrow when the Texas Rangers face the Houston Astros.

This is WEEKEND EDITION from NPR News. I'm Scott Simon and we'll have to wait until June to learn what the U.S. Supreme Court has decided on the two gay marriage cases before it.

We're joined now by NPR legal affairs correspondent, Nina Totenberg. Thanks for being with us.

When does a story about science become science fiction? Cosmologist Lawrence Krauss and theoretical physicist Brian Greene discuss how to spin a yarn about string theory or the Big Bang, without hyping the science.

The Sonoran Desert, which spans some 100,000 square miles in southwestern North America, is one of the most diverse desert ecosystems in the world. Host Ira Flatow and guests discuss some lesser known desert creatures, and explore the secret life of that American southwest icon, the saguaro cactus.
