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.
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. And novelist Ian McEwan, whose books touch on neurosurgery and quantum field theory, talks about what science offers to fiction.
You're listening to SCIENCE FRIDAY. I'm Ira Flatow. And for the rest of the hour we're going to talk about collisions, space collisions, space impacts, with Erik Asphaug, who's Ronald Greeley chair of planetary geology, School of Earth and Space Exploration at Arizona State University. Welcome to SCIENCE FRIDAY.
ERIK ASPHAUG: Thanks very much, Ira.
FLATOW: You must be very busy since this last collision in Russia of this asteroid.
Driving in northern New Mexico requires special caution on Good Friday. Tens of thousands of people — some walking all night — are converging on the village of Chimayo to pray inside a 200-year-old chapel before a carved wooden image of Jesus.

The cyclist, Andree, is on her way to pose for an elderly Impressionist painter, Pierre-Auguste Renoir (Michel Bouquet), whom she somewhat startles by claiming to be an artist herself.
A New York landmark of sorts is in danger of being wiped off the map. The building now known as Broken Angel was an ordinary 19th-century brick structure until self-taught artist and sculptor Arthur Wood started building on top of it in the late 1970s. Now Wood faces eviction from his own masterpiece — a towering structure that looks like a cathedral built out of salvaged junk.
When fortunes rise in the housing industry — as they currently are — it tends to lift sales for other businesses, too. Home construction, sales and prices are all improving. And according to many analysts, the market is gaining steam.
