The mysteries of the octopus

The octopus is one of the most bizarre life forms on Earth – one of the smartest, most interesting, and most alien. It can camouflage itself in a flash, squeeze its entire body through a one-inch hole, and use their brains (yes, it has nine of them) to think and play. Chip Reid visits scientists at New England Aquarium in Boston, and the Marine Biological Laboratory in Woods Hole, Mass., and talks with Sy Montgomery, author of "The Soul of an Octopus," about these curious creatures.

Gary Clark Jr. on "This Land"

At 35 Gary Clark Jr. is still clearly uncomfortable being heralded as one of the best guitarists in a generation. He's played the White House, and toured with the Rolling Stones and Eric Clapton.

Kristine Johnson talks with the musician who describes himself as a "simple dude from Austin, Texas who picked up a guitar."

He spoke (somewhat evasively) with correspondent Charlie D'Agata about his improbable journey.

Sunday Profile: Kim Novak

Overdue protections for pregnant workers

It's a story told hundreds of thousands of times every year across America: Women can get the job – just don't get pregnant. Even though pregnancy discrimination has been illegal under federal law for more than 40 years, pregnant women are pushed out of their jobs every day, because employers still deny accommodations to pregnant workers. Jan Crawford talks to women who have faced serious choices and sometimes tragic circumstances affecting careers and family; and with two lawmakers trying to change federal law to better protect women in the workplace.
