Joe Palca en The Scientist Who Makes Stars On Earth Transcript <p>AUDIE CORNISH, HOST: <p>From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.<p>On the outskirts of Albuquerque, New Mexico, scientists are doing something astonishing. They're creating a white dwarf star - not a whole star but enough of one to study in minute detail.

He says it's relatively easy to make membranes that can filter the bacteria out of water.

We've always been told that magnets have two poles, north and south. But theory suggests there should be something called a magnetic monopole, a magnet that has either a north pole or a south pole but not both of them. So far no one has found this elusive magnetic monopole.<p>As part of his project, Joe's Big Idea, NPR's Joe Palca brings us the story of scientists at Amherst College in Massachusetts. They have created a synthetic magnetic monopole.

For the past 31 months, the spacecraft has effectively been asleep. Most of its instruments were shut off to save energy, including the radio for communicating with Earth. Mission managers can now start preparing Rosetta for a rendezvous with a comet later this year. NPR's Joe Palca has more.<p>JOE PALCA, BYLINE: Rosetta went into hibernation in June 2011.

NPR science correspondent Joe Palca will be one of those obsessed, screaming fans. It's not often Joe gets to do a story that mixes science and soccer, but as part of his new project, Joe's Big Idea, he found a computer scientist who actually studies soccer using robots as players.

So a straight wire made from one of these "shape memory alloys" might change back into a spring when heated, or vice versa. But the alloys that exist today change shape at low temperatures. Materials scientists at Sandia National Laboratory have developed new alloys that don't change shape until they reach hundreds of degrees, opening the door to thousands of new applications.

I'm Robert Siegel.<p>Car companies have already begun to design cars that can drive themselves. But to make these smart cars really useful, they'll also need smart roads. As part of his series, "Joe's Big Idea," NPR science correspondent Joe Palca has this story about some computer scientists who were designing a smart traffic intersection. How smart?
