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.
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.
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.

Last August, Jeffrey Lewis saw a North Korean propaganda video, posted in April 2012, which showed its missile launchers holding intercontinental ballistic missiles, shot from an oddly-shaped building.
He was curious. So with a team of students, he modeled what the building would look like and searched for what North Korean defectors had said about the building where the missile launchers were supposedly made.
"I will admit I got a little bit obsessed with this," he says.
The online magazine Ozy covers people, places and trends on the horizon. Co-founder Carlos Watson joins All Things Considered regularly to tell us about the site's latest feature stories.
This week, Watson talks with host Arun Rath about a new texting service that promises tight security. While Snapchat has become a popular way to text photos that disappear after a number of seconds, recent hacks have raised questions about its security. A service called Privatext provides an alternative that has gained interest among some professionals.

It has been an ugly winter. In the past two weeks, a pair of storms has made life miserable across the Eastern U.S. On Thursday, much of the south and northeast were buried in snow and ice.
