Warming Arctic May Be Causing Jet Stream To Lose Its Way

The jet stream that circles Earth's north pole travels west to east. But when the jet stream interacts with a Rossby wave, as shown here, the winds can wander far north and south, bringing frigid air to normally mild southern states.

Floods or Family Conflict? Bad Dreams Differ By Gender

Originally published on Sun February 16, 2014 11:44 am

RACHEL MARTIN, HOST:

I think it's safe to say most of us do not enjoy nightmares - that cold sweat, sitting up straight in bed, our pulse racing. But when Antonio Zadra, professor at the University of Montreal, began working on a study about nightmares he found that the narrative animating those bad dreams tended to be very different between men and women. He is coauthor of a new study that has a lot to say about the differences in the way we dream. He joins us now from Montreal. Welcome to the program.

ANTONIO ZADRA: Thank you for having me.

Scientists Discover Universe's Oldest Star

(SOUNDBITE OF THEME MUSIC, "STAR TREK")

RACHEL MARTIN, HOST:

Scientists have discovered the oldest star in the galaxy. And it's really old, 13.6 billion years. Now to be clear, they had known about this star before but hadn't yet figured out its age. This star is four billion years older than any other star found to date.

Here to more to talk about what this star can tell us about the great beyond is Timothy Beers, of the National Optical Astronomy Observatory in Tucson, Arizona. Thanks so much for being with us.

No Rest For The Snow-Weary: Northeast Braces For Round 2

But wait, there's more: New England is still digging out from the massive snowstorm earlier this week.

The Northeast is in for another winter punch, with the National Weather Service calling for more than a foot of accumulation in many areas through early Sunday. The double-whammy comes even as many areas are still digging out from the last assault a mere two days ago.

Mars 'Jelly Doughnut' Mystery Solved: It's Just A Rock, NASA Says

This composite image provided by NASA shows before-and-after images taken by the Opportunity rover on Mars of a patch of ground taken on Dec. 26, 2013, showing the "Pinnacle Island" rock.

It appeared out of the red, like something dropped by a Martian Homer Simpson. But now NASA has an explanation for the "jelly doughnut" object photographed by the Opportunity rover in December.

First, here's what it isn't: It is not a fungus-like Martian organism, nor is it ejecta shot into the air by a nearby (and unseen) meteor impact.

Instead, it's geologic roadkill. Basically.

"We drove over it," Opportunity's Deputy Principal Investigator Ray Arvidson said in a statement on Friday.

SCOTT SIMON, HOST:

You know, athletes burn a tremendous number of calories in competition and training and with the Olympics underway we got to wondering just what they consume to recover from a workout and fortify themselves for upcoming events. So we're reached nutritionist Nanna Meyer in Sochi. She teaches at the University of Colorado at Colorado Springs and she is the U.S. Olympic speedskating team sport dietician there are the games.

Thanks very much for being with us.

NANNA MEYER: Thanks very much for having me.

A quarter of Americans surveyed could not correctly answer that the Earth revolves around the sun and not the other way around, according to a report out Friday from the National Science Foundation.

The survey of 2,200 people in the United States was conducted by the NSF in 2012 and released on Friday at an annual meeting of the American Association for the Advancement of Science meeting in Chicago.

Illegal, Remote Pot Farms In California Poisoning Rare Wildlife

Fishers are among the small carnivores threatened by rat poisons used to guard plants at illegal marijuana farms.
John Jacobson U.S Fish & Wildlife Service

People who grow marijuana illegally in the backwoods of Northern California use large amounts of rat bait to protect their plants — and these chemicals are killing several species of wild animals, including rare ones, biologists say.

Here's what happens: The growers plant their marijuana in remote locations, hoping to elude detection. They irrigate their plants — with water from streams — which lures animals looking for water. Rodents chew the flourishing plants to get moisture, which kills the plants. Researchers believe that's the prime reason growers use the poisons.
