Talk of the Nation

NEAL CONAN, HOST:

This is TALK OF THE NATION. I'm Neal Conan in Washington. Late last week, North Korea responded to new U.N. sanctions with hyperbolic language. A statement described the new measures as a declaration of war. Pyongyang deserves special vitriol for the United States, our sworn enemy, it said. A new nuclear weapons test would target the United States, and it described its new long-range missile as designed to strike U.S. territory.

As lawmakers in Washington debate job creation, and unemployment rates remain high, the temporary labor workforce continues to grow.

A bipartisan group of senators is released a proposal for immigration reform. The plan specifically addresses creating a path to citizenship, employment verification systems and worker recruitment programs and raises many questions about potential changes for immigrants and employers.

Unusual activity in the atmosphere over the Arctic Circle is triggering snow and frigid temperatures across Canada, the U.S. and parts of Europe. Climatologist Jeff Weber, of the University Corporation of Atmospheric Research, explains why this winter could pack a punch.

Reporting in Nature, researchers write of encoding a variety of files--jpg, mp3, txt and pdf--in strands of DNA. Lead author Nick Goldman says DNA is extraordinarily long-lasting, compared to today's hard drives and magnetic tapes. And if all the world's information were written in DNA, he says, it would fit in the back of a station wagon.

It's that time again, the SCIENCE FRIDAY Book Club. Regulars are gathered here. With me are Flora Lichtman, correspondent and managing editor of video for SCIENCE FRIDAY, Annette Heist, our senior producer. And this month, we had a page-turner, "The Andromeda Strain."

FLORA LICHTMAN, BYLINE: Yes.

FLATOW: It goes very quickly, that book, doesn't it? Poof.

LICHTMAN: It did. I was thinking of 300 and something-odd pages, but I, you know, in one sitting, was halfway through. I couldn't put it down.

We didn't have a chance on Monday to get to our opinion page, so now a special Thursday edition of the opinion page. This week marks the 40th anniversary of Roe v. Wade, the landmark Supreme Court decision. In a recent piece for The New York Times, that newspaper's former Supreme Court correspondent, Linda Greenhouse, wrote that the ruling that legalized abortion across the entire country was much more about the rights of doctors than the rights of women.

This is TALK OF THE NATION. I'm Neal Conan in Washington. In a piece in The Atlantic, neuroscientist Daniel Levitin describes the day a teacher, a famous neuropsychologist, told the class that his colleague, a close friend, had just called him to say he had a brain tumor, would gradually lose his memory and, the teacher said, would soon no longer understand who he was.

The military's lift of the combat ban for women potentially opens up thousands of front-line positions, but many women in uniform argue they've long served in front-line units. Host Neal Conan talks to Lt. Col. Samantha Nerove about what the change may mean and her experiences in the military.
