Originally published on Tue April 29, 2014 3:44 pm

Tornadoes killed at least 17 people on Sunday and Monday. But some managed to stay safe in underground shelters like the one at right in Vilonia, Ark.

Deadly tornadoes have wreaked havoc in the South, leveling homes and claiming at least 28 lives in the past three days. And meteorologists say the threat of more tornadoes won't ease up till Wednesday.

Getting to a safe place is the best thing that people can do to protect themselves and their families. That can mean a specially constructed concrete safe room, a basement, or just a ditch if you're caught outdoors.

Velocity: It's All Relative

The Concorde was fast and changed how we thought about travel here on Earth. In the future, we may well travel at speeds that change our relationship with time itself.

We spend a lot of our lives getting from here to there. Everyday we slog from home to work and back again. Once a week we make the trek to the grocery store. A few times a year we take vacations across the state, the country or even across an ocean. Each trip, large or small, sets us in motion.

We get going.

We get up to speed.

Between Farmers And Frackers, Calif. Water Caught In Tussle

Originally published on Thu May 1, 2014 1:08 pm

Transcript

MELISSA BLOCK, HOST:

Water supplies in California are tight with the state's severe drought and that's putting a spotlight on hydraulic fracturing or fracking. The controversial oil and gas extraction technique uses freshwater, which can mean millions of gallons for each fracking site.

Lauren Sommer of member station KQED reports from California's Central Valley, where tensions between oil and agriculture are on the rise.

Keith Cowing discusses his campaign to save an old 1970s NASA spacecraft from becoming space junk. ISEE-3/ICE is a satellite that was once used to monitor space weather, but it's been unused for decades. NASA doesn't want to spend the money to bring it back to life, but Cowing and his colleagues are determined to do it. If they can raise $125,000 on a crowdfunding site called RocketHub, Cowing says they'll contact ISEE-3/ICE, wake it up and put it back to good use.

Got Gas? It Could Mean You've Got Healthy Gut Microbes

Originally published on Thu May 1, 2014 12:02 pm

Sulfur-rich foods, such as cabbage, bok choy and kale, can be popular with gut bacteria. And we all know how much the critters enjoy beans.
Meg Vogel/NPR

Not long ago, we heard about a catchy idea for a cookbook: "Fart-free food for everybody."

In theory, these recipes would be helpful for some people — and those in their vicinity.

But being a bit gassy may actually be a small price to pay for a lot of benefits to our health.

For the past month, in part of eastern Kansas, the prairie has been burning, as it does almost every spring. On some days, you could look toward the horizon in any direction and see pillars of smoke. The plumes of pollution have traveled so far that they've violated limits for particulates or ozone in cities as far away as Lincoln, Neb.

But here's the twist: Environmentalists have come to celebrate those fires.

This month, NASA revealed new details of the plan to send humans to Mars by 2030. It's an elaborate and expensive mission, involving a giant deep-space rocket, and roping an asteroid into the moon's orbit to use as a stepping stone to Mars.

But there are still some serious questions about a manned expedition to Mars. Namely, is it safe? That's where astronauts Scott and Mark Kelly come in. The Kelly brothers are identical twins, and the only siblings ever to both fly in space.

Huge lines of people, kids in tow, are waiting to get into the Smithsonian's National Museum of Natural History, the world's second-most visited museum.

Right inside the lobby, a cast of the skull of the new Tyrannosaurus rex the museum just acquired is stopping visitors dead in their tracks.

"We wanted to get up here before the exhibit for the dinosaurs closed," says Crystal Epley, who took a three-hour trip from Broadway, Va., to bring her son, John.
