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.

But at All Things Considered, we put on a two hour program, no matter what. So — without a trace of irony — one of our science correspondents offered to help fill some holes in the show with a series of stories about holes. In this edition: Black holes.

I'm Robert Siegel.<p>A program such as ours is timed to the exact second, and occasionally, there are small holes when our mix of news and features doesn't quite fill up our two-hour slot.<p>So NPR's Joe Palca offered to come to our rescue with some short math and sciencey hole-filling stories, stories about what else - holes.<p>JOE PALCA, BYLINE: Today, we're going to talk about doughnut holes, those round things you buy in a bakery.

Sunrise At Honolulu's Fish Auction http://wkms.org/post/wake-and-smell-tuna-sunrise-honolulus-fish-auction If you are up at 5 in the morning in Honolulu and are wondering what to do, I have a suggestion: Head over to Pier 38 and watch the Honolulu Fish Auction. It's quite a scene.<p>Getting up at 5 may seem a bit extreme, but for recent arrivals to Hawaii from the East Coast of the mainland — as I was last Friday — the six-hour time difference makes waking up early easy, if not inevitable.<p>The auction takes place in a low-slung single-story building toward the end of the pier. At about 1 a.m., fishing boats start bringing in their catch. Tue, 07 May 2013 16:04:00 +0000 Joe Palca 31504 at http://wkms.org Wake Up And Smell The Tuna? Sunrise At Honolulu's Fish Auction
