This is TELL ME MORE from NPR News. I'm Michel Martin. Coming up, you've heard the pundits and the politicians give their take on the new S-word - sequestration. We'll ask the Barber Shop guys for their perspective on this later in the program. But first we want to talk about another big topic in Washington this week. That is the challenge to the landmark Voting Rights Act of 1965. That's before the Supreme Court, specifically section five of the act.

This fall, health insurers in a few states will be seeing stars.

Not the celestial kind, but stars that reflect their scores on quality measures picked to help consumers make informed decisions when buying health coverage.

As I just mentioned, the automatic spending cuts go into effect today, covering much of the federal budget, and we were trying to talk with Lamar Smith about where those cuts might come, obviously across the board. Well, someone who might be more forthcoming or know more about it is here with us, Michael Lubell. He is professor of physics at City College at the City University of New York, director of public affairs at the American Physical Society. He's here in our New York Studio. Good to see you again.

Rep. Lamar Smith (R-Texas), Chairman of the House Committee on Science, Space and Technology, discusses the nation's top science priorities, including the importance of research on how to protect Earth from dangerous asteroids. But in a tight budgetary climate, who will pay?

Whole wheat, stone-ground, multi-grain. Have food labels got you confused? Joanne Slavin, a nutrition professor at the University of Minnesota, and David Ludwig, a pediatrician and obesity doctor at Boston Children's Hospital, discuss the meaning of "whole grain," and whether intact grains like wheat berries pack more nutritional punch than their ground-up counterparts, such as whole wheat flour.

Far above the Earth's surface, two doughnuts of radiation surround the planet, charged particles zipping around in stable belts - that's the shape of them - and they were discovered in 1958 by James Van Allen and now bear his name. They are the Van Allen Belts.

Robert Langer is sort of a modern-day Thomas Edison. He holds over 800 patents. He's launched two dozen startups making an eclectic variety of stuff from tumor-zapping nanoparticles to biosensors and blood tests, synthetic spinal cords, even anti-frizz hair products, all of this originating from the same lab. And recently, President Obama awarded him the National Medal of Technology and Innovation. He's already won the National Medal of Science, after all.
