Fresh Air on KRVS

There's enough DNA in the human body to stretch from the sun to Pluto and back. But don't confuse DNA with your genes, says writer Sam Kean.

"They are sort of conflated in most people's minds today but they really are distinct things," he tells Fresh Air's Terry Gross. "Genes are like the story and DNA is the language that the story is written in."

As a child, astronomer Jill Tarter would walk along the beaches of western Florida with her father and look up at the stars.

"I assumed, at that time, that along some beach on some planet, there would be a small creature walking with its dad and they would see our sun in their sky, and they might wonder whether anyone was there," she tells Fresh Air's Dave Davies. "But I never thought about it professionally until graduate school."

Many jazz musicians, the kind who wear jackets and ties on stage, are often carelessly referred to as playing bebop. In reality most of them are post-boppers, who build on that dynamic style that burst forth after World War II, without bringing it back in pure form. It's the rare modernist who gets an authentic bebop sound on alto saxophone, who catches some of the raw explosiveness and rapid-fire grace of jazz god Charlie Parker. And then there's Jesse Davis.
