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.

What that means is they were caused by a doctor in the course of the treatment.<p>Sometime these iatrogenic injuries are accidental. But sometimes, because of the limits of medical technology, they can be inevitable.

But don't worry — that happens from time to time.<p>"A coronal hole is just a big, dark blotch that we see on the sun in our images," says <a href="http://sdo.gsfc.nasa.gov/mission/team/team_pesnell.php">Dean Pesnell</a>, project scientist for NASA's <a href="http://sdo.gsfc.nasa.gov/mission/team/team_pesnell.php">Solar Dynamics Observatory</a>. "We can only see them from space, because when we look at them [through] a regular telescope, they don't appear."<p>That's because you have to look at wavelengths of light that the human eye can't see.
