This is SCIENCE FRIDAY. I'm Ira Flatow. We're here in California, broadcasting from the California Academy of Sciences in San Francisco. And just outside the Golden Gate, of course, is the Pacific Ocean. It is the largest body of water on Earth, and its trenches are also the deepest. You could put Mount Everest into some of them, and the top would not even peek out.

JOHN DONVAN, HOST:

This is TALK OF THE NATION. I'm John Donvan in Washington. Earlier this month, nine immigrants suspected of being illegally smuggled into the United States were killed in a car crash. That journey came to a violent and sudden end. But there have been, and there will be others bent on crossing the Mexican border north to the U.S. who will make that very same journey and with a similar setup.

Columnist Crawford Kilian advises aspiring writers to avoid Jack Kerouac's On the Road, Ayn Rand's Atlas Shrugged and eight other well-known novels.

But Kilian isn't saying they're bad novels — quite the opposite, actually. In a piece for the Canadian online daily The Tyee, Kilian writes, "their readable styles look so easy that they might seduce a young writer into imitating them."

The son of Ruby Dee and the late Ossie Davis, Guy Davis initially followed in his famous parents' footsteps. But then he discovered the blues in college, and now travels the world performing in places untouched by the genre, from Greenland to the Galapagos Islands.

Known as "The Ambassador of the Blues," Davis talks with NPR's John Donvan about his new album, The Adventures of Fishy Waters: In Bed With the Blues, and his passion for blues music.
